4 Claims.

This invention pertains broadly to statistical systems, and more specifically relates to apparatus for verifying statistical data recorded upon records, in the form of index marks, which records are adapted for use in statistical machines,

v.the said index marks controlling the statistical operations of the machines.

It has been suggested to employ a continuous photographic lm record having coded data desin the individual frames orareas of the film record, for controlling the operations of various statistical machines. The individual frames or areas of data designations, which designations may be in the form of photographic spots or marks, are formed at successively spaced intervals along the lm and will be referred to as individual records. It has also been suggested to employ colored photographic lm records having the data designations formed thereon in different colors for controlling` the operations of satistical machines. In the present invention the said individual records will be shown to comprise groups of data designations in the form of discrete and differently colored spots or marks which are disposed in different positions in different columns on the photographic lm records, so as to represent by their relative positions thereon the values thereof. The photographic records described in the present application are claimed in a separate and copending application, Serial No. 282,209, filed June 30, 1939 now Patent No. 2,268,499 issued December 30, 1941.

The subject matter of the instant application relates solely to the means for verifying the photographic records bearing the dilferentially positioned and colored index marks or spots. Means are provided whereby the verifying or I comparing data is set up and stored for controlling the verifying operations. Such means, in the instant disclosure, comprise manually operable keys, which upon depression are latched in a depressed position for maintaining the selection of control circuits associated with the said keys. Differentially timed impulses, which are initiated by suitable record sensing means upon sensing the photographic marks or spots, are routed through the Various verifying circuits set up by the said keys, by means of a commutation device operated in synchronism with the record sensing means, whereby control relays are energized upon the disagreement of the sensed and stored data. indicating lamps are provided, and the energization of which are controlled by the said relays indicating the numerical and color values of the data sensed on the records, which data are in disagreement with the data set up in the verifying keyboard. Additional means are provided to mark or perforate those records containing data thereon found to be in error.

Therefore, an object of the present invention resides in the provision of means for verifying the ycolor anddata values of the colored data designations which are sensed on individual control records.

Another object of the present invention resides in the provision of means for indicating the relationship of both the color and data values of the compared or veried data designations.

Another object of the present invention resides in the provision of means for normally preventing further verifying operations of the machine upon the detection and indication of. a disagreement between the sensed and verifying data designations.

Other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principle of the invention and the best mode, which has been contemplated, of applying that principle.

In the drawings:

' the circuit connections of the machine.

Photographic control records' I Referring now to Fig. 1, the photographic .con- I trol element 20 shown thereinis a fragmentary section of a continuous strip of photographic color film, provided with the usual feed apertures 24, upon whichlm are formedv a plurality of individual'recordsV a to c comprising groups of data designations 22 in the form of discrete and differently colored control spots. One type of color film which is suitable for the purpose described in the instant application is the Agfacolor film, which comprises a single unitary film structure consisting of a support upon which is coated in thin superimposed layers a plurality of light sensitive emulsions, each particularly sensitive to one of the primary colors. By exposing such a lrn to a colored object, three separate color records are recorded. simultaneously, each sensitized layer recording the image to which it is coler= sensitive. The color formation is brought about by the development of the film. Assume that the film 2Q has been suitably exposed to record the` data thereon in color, and that the color formation of the data as designated is brought out by development of the recorded lm.

The spot representation 2l on each record represents supplemental control data, and the spot representations 22 represent amount data. The data represented by the reference character 23 is shown merely for interpreting the associated coded control spots and are not used for controlling machine operations. Assume that the data shown in the individual records a and b are formed in red color, the data in record c in blue, the data in record d in green, and the data in record e in black.

The spot representations 2| and 22 are photographic machine control spot representations, and each set of numerical data comprises one or more control spots in such relative position, in different columnar areas, upon the lm record as to represent by their relative position thereon l the numerical control value thereof. In practice and according to the embodiment shown, such numerical spot representations are shown on the film in index point relation in general conformance with the manner in which index perforations are disposed on perforated record cards in the Hollerith accounting system. That is, the differential position of a control spot representation delineates the numerical value of a particular numeral. This will be clear by referring to the figure and particularly record a, wherein the data represented by the designations or control spots 22 represent the amount twenty-seven.

It Will be understood that the completed film has photographic reproductions thereon at successively spaced intervals along the lm, and that the reproductions are in extremely compact form, accordingly, a large` quantity of statistical information can be placed on an extremely small controlling record.

Method of analyzing color of data designations Referring now to Fig. 2, the method of analyzing the Colored control spots formed on the lm Will noW be explained briefly. Assume thatthe film is advanced in the direction shown by the arrow past the sensing station which is rep.- resented by an aperture 25 in the opaque member 26, and that the color of a control spot presented to the said sensing station is red. Light` rays4 sume that the lter 3l is a cyan color filter designed to pass the different colored rays excepting red rays which are absorbed by this filter, that the filter 32 is a magenta color filter permitting the colored rays, with the exception of green to pass therethrough, and that the filter 3 3 is a yellow color filter permitting the colored rays, with the exception of blue, to pass therethrough.

Now, since the red light rays are directed by the individual legs of the quartz member 30 to the individual lters 3i to 33, it is understood that the said rays are permitted to pass through the magenta and yellow filters to impinge upon the associatedy photocells 29h and 29e, respectively, but are absorbed by the cyan filter so that no light rays aretransmitted to the associated photocell 29a. Upon presentation of a blue control spot to the sensing station, it is seen that the cyan and magenta filters permit the rays to be transmitted to photocells 29a and 29D, respectively, Whereas no blue light rays are transmitted by the yellow filter to the photocell 29C, and upon sensing a green control spot, light rays are transmitted to photocells 29a and 29e but not to photocell 29h. In the event that a black control spot is presented to the sensing station, no light rays are transmitted to any of the three photocells, namely, 29a to 29e.

Suitable amplifiers 34 `are connected to the said photocells 29a to 29e (see Fig. 9a), in a manner well known in the art, so that it is considered necessary only to state that when light rays are impinging on the photocells the associated ampliers are conditioned so that no current iiovvs in its output circuit, Whereas, When no lightl rays are transmitted to the photocells the associated amplifiers are conditioned so that current flows in the output circuits thereof as long as the light rays do not impirige thereon. The purpose of this arrangement will be understood as the description progresses.

Film feeding and sensing means Referring now to Figs. 3, 4 and 5, the photographic color nlm 2l] is Yshovvn disposed on a sup.- ply spool or reel 35. The nlm is attached to a talefup reel 355, and may be advanced by suitable driving connectionsl cooperating with shafts 31 and 38, by means of suitable ilmfeeding sprockets 3 9 and 4G secured to the said shafts, respectively, which sprockets cooperate with the film feed apertures 24 in the film. The lm is fed past the analyzing station comprising the sensing aperture 25Y and transilluminated by the light rays emanating from the light source 2l and directed thereto by the condenser 23. The said scanning aperture is arranged to present an opening sufcient to permit the scanning of a single transverse row of data or control spots only, and is provided to extend transversely across the film record to any desired extent so as to permitthe desired columns o-n the film to be sensed. The reference characters 29o, lila, and 62a designated inFig. 4 represent the plurality of rows of photocells which are disposed at the analyzing station `and controlled by thelight rays impinging thereon. Each row of photocells, in the present illustration, comprises three photocells, for example, in Fig. 3, they are designated 29a to 29e. It is understood for eachv columnararea on theviilm, three individual photocells are provided and arranged 1 as described. For each row. or orderrof photocells, a three way light conducting member. 30, is` provided,v saidmember comprises a quartz rod .member having. three conducting legs for. transmitting the light rays from the sensing aperture to the associated photocells. Thesaid quartz members are suitably supported by the block 43, and as mentioned the legs thereof extend fromeach photocell to the analyzing station where the common legs are positioned adjacent to one another along the sensing aperture. The spacing of the common legs of the quartz members along the said aperture is so arranged that each leg is positioned opposite'one of the columns of control spots disposed `on the lm. In this manner, the light rays directed to the sensing aperture can be conducted to the associated photocells to condition the latter for machine control operations during the sensing operations.

As mentioned before, individual color lters 3l to 33 are provided to be interposed between the individual legs of the quartz members 3D and the associated photocells. In Fig. 3, the color filters designated 3| to 33 are the cyan, magenta vvand yellow color filters referred to hereinabove yfor the purposes set forth. It is'understood that the three filters are provided for each order and interposed between the legs of the quartz members and associated photocells as shown in Fig. 3.

The lm feeding means and control means therefor, comprise generally the clutch magnet -44 and the associated pivoted armature 45 to which is secured a latch lever 46A normally engaging an extension 41 of the member 48 secured to shaft 38, and the clutch pawl 49, pivotally supported by member 48 and normally disengaged from the clutch element 56 by means of the said latch lever. Upon energization of mag# net 44, the latch lever 46 is caused to release the pawl 49 and engage the clutch element 56 which is rotatably mounted on shaft 38 and rigidly se-A cured to gear 5| which is driven by suitable means such as the gear 52, drive pulley 53 and the associated driving connection 54. Thus it is seen, whenever the driving connections are operated, and the magnet 44 energized, that shaft 38 is rotated and in addition thereto gear 55, which is secured thereto, to rotate gears 56 and 51 the latter being secured to shaft 31, thereby rotating said shaft and causing the respective feed sprockets 46 and 39 to feed the film to the analyzing station. The control spots disposed on the lm are then effective to modify the light rays emanating from the light source as described hereinabove for controlling the conditioning of the associated photocells.

It should be mentioned that film supply control contacts 66 (Fig. 5) are provided and adapted to be closed by the suitably pivoted lever 6I as long as the film is presented to the analyzing station; however, when the lm supply is exhausted the said lever swings to the left as viewed in Fig. 5 to open the contacts 66. Opening of contacts 68 exercises a controlling function whereby further machine operations are prevented upon exhaustion of the lm supply in a manner well known in the art. Such a controlling function is described in U. S. Patent No. 2,196,166. Onshaft 31, a plurality of cams 62 are provided (only one of which is shown in Fig. 3) for controlling the contacts CI to C6 (Figs. 9a and 9b) so that the said contacts are closed at different times durin the machine cycle as indicated in Fig. 8.

Associated with the film feeding means are suitable marking means for marking the individual frames or records of the film which are 4found to be in error, so that they can be readily f located and replaced by corrected records. The .marking means shown comprises punching means (see Fig. 5) for notching the records which are lin error. In Fig. 1, a notch 63 is shown formed in record e and is suitably disposed along the -marginal edge of the film record. The said marking means is located below the sensing station and consists of a punch 64, mounted in a block 65, which punch is held in the position shown by means of a compression spring 66. The punch die 61 is shown as an integral part of the member 26. The operation of the punch 64 is controlled by magnet 68, which upon energization attracts the armature 69 secured to the pivoted lever 10 to cause the said lever to engage and operate the punch`64. In this manner, the individual records can be marked whenever the magnet 68 is energized. The circuits for controlling the energization of magnet 68 will be described hereinbelow. Contacts 1| and 1ml are provided andsuitably positioned in the path of vthe lever 16 so that upon `energization of magnet V68 the said lever will cause the contacts 1I to be openedV and contacts 1Ia. to be closed at the moment the armature 69 engages .the core of the said magnet. The purpose of the said contacts will be understood as the description progresses.

Keyboard section Referring now to Figs. 6, 7 and 9a. the keyboard 'section is shown to comprise a plurality of columns or orders of individual keys. The number of keys in each order can vary as desired, however, in the instant case an individual key is provided for each index mark or point position in the individual columns of the records, and for each color designation appearing on the lm records. The purpose of the keyboard section is to provide means for storing the desired comparing data.

Provision is made whereby upon depression of the individual keys 15 against the action of the associated springs 16, they are held latched in the depressed positions by the related latch bars 11 (of which one for each order of keys is provided). Each key bar is provided with a V- yshaped conducting portion 18 adapted to engage normally the related contacts 19. This connection will be referred to as contacts A on the wiring diagram. Upon depression of any selected key 15, the associated conducting portion 18 is disengaged from the related contacts 19, or stated in other Words, upon depression of any selected key the associated contacts A (see wiring diagram) are opened.

The verifying operations of the machine are initiated by the manual operation of a motor bar 86, the depression of which causes the contacts 8| to be closed. By means of a latch lever 82 the depressed bar is maintained so, due tc the engagement of the stem 83 of the bar with the said latch lever. Upon completion of the verifying operations means are provided, such as solenoid 84, to be energized to restore the motor bar to its normal position. It is seen that energization of the solenoid causes the pivoted latch member 82 to be partially rotated in a clockwise direction upon .displacement of the solenoid plunger by means of the link 85 thereby releasing the latched stem 83 of the motor bar.

During the said rotation of latch member 82 and after the release of the motor bar the link 86 causes lever 81 to be partially rotated and in -turn to rotate the shaft 88 in a counterclockwise direction. Rotation of shaft 88 effects displace'- ment of the arm 89 (secured to said shaft) 'and transverse bail 90, which bail, upon being rocked, thrusts the latch bars I1 forwardly (to the left as viewed in Fig. 6) releasing any depressed keys which have been latched down. For a more de'- tailed description of this well known type of key-'- board reference may be made to U. S. Patent No. 2,147,626.

- Operation vof the machine Referring now to Figs. 8, 9a, and 9b, the 'cle'- scription 'of 'the operation of the machine will be given. Assume that, upon closure of switches SI and S2 the light source and amplifiers 34 are provided with suitable potentials, that suitable driving means are effective to rotate continuously the driving gear 52, and furthermore, that the photographic film 20 is properly arranged in the feeding and sensing unit.

The first step in the operation of the instant verifying machine comprises setting up the Verifying data upon the keyboard section. The selected keys 15 representing the verifying data are locked in the depressed positions, as described hereinabove, to maintain the associated A contacts open during the verifying operation. The individual columns of contacts shown in Fig. 9a, and 'indie cated U, T, and H, are controlled by the units', tens and hundreds order keys 'I5 of the keyboard section, respectively. It is seen that numerical and color designating keys are provided. For each record to be verified, the number and color keys are depressed in accordance with the data which is assumed to be recorded and represented on the record and the color designation of the data representing spots. The corresponding contacts A of each order or column of contacts are connected individually to the pickup coils of the associated relays of the groups of relays designated URI to URI4, TRI to TRI4, and HRI to HRI4.

rIhe stationary conducting segments of a suitable commutation device 99 are connected individually to the groups of pickup coils of all the orders representing the different numerical and color designations, so that upon rotation of the conducting brushes I0'I the pickup coils of relays URI, TRI, HRI, UR'2, TR2, HRZ, etc. associated with the individual contacts A are connected successively to the common conducting ring |02 and the pickup coil of relay RI8. It should be mentioned that the brushes IOI of the commutation device are mounted on the shaft 31 of the film feeding unit (Fig. 3) 'and arranged to engage the conducting segments |00 in synchronism with the presentation of the index point positions of the individual records to the sensing station. For example, when the 5 index point positions of a record are presented to the sensing station, the brushes IOI are arranged to engage the "5 conducting segment which is connected to the pickup coils of relays UR5, TR5, and HRS, which coils in turn are connected to the individual "5 contacts A of each order. In this manner, the stored data in the keyboard section can be read out in timed relationship with the sensing of the data recorder on the individual records.

The data verifying capacity of the instant machine as disclosed is limited to three orders. However, it is evident that the capacity can be expanded to any desired extent by providing for each order of data to be veried the connected control elements shown, in the circuit diagram.

It was described hereinabove how the different colored spots on the records are analyzed and conassesses trol the conditioning 'or activation of the photocells. Upon sensing red-spots `in the 'columns on the records, the photocells 29a, '4|a, and 42a, for example, are not activated by the light rays, and thereby render the A'connected 'amplifiers 34 conductive to energize the associated control relays AR, BR and CR. Upon Asensing the green spots the Vrelays AG, BG and C'G are energized, and upon sensing the blue spots, the relays AB, BB, and CB are energized. It was stated, whenever black `spots are sensed, no light rays are transmitted to the photocells. Therefore, it is seen that all the said relays AR, AG, AB, BR, etc. are energized.

The said relays are energized at the different times the control spots are sensed to establish the different data verifying circuits. For example, assume that 'one of the records to be veried has recorded thereon in red colored spots, the number A125, `and 'assume further that the vsaid numbers and `the said color designations are setup in the keyboard section so that the red contacts A and the corresponding 1, 2, and "5 contacts A of fth'ehund'reds, tens and units orders, Vrespectively, are held open during the'ensuing machine cycle. Now, upon depression of the motor bar or start key 80,the contacts "8| are closed to complete a circuit from conductor y|03 to'contacts 8| and RIEb, coil of'magnet f44 to conductor |04, energizing said magnet, and thereby effecting feeding of the record past the sensing station. Upon sensing the differentially disposed data'representing spots, the relays AR, BR and CR are energized at vthe 5, 2, and 1 'points in the machine cycle respectively, to effect operation of the associated contacts `ARI to AR4, BRI to BR4, and CRI to CR4.

Since the brushes IIlI of the commutation device are positionedin'timed relationship with the feeding of the record, the 5, "2, and 1 conducting segments -I00 which are connected to Ithe pickup coils of relays URB to HR5, URS to HR8, and URS to HRS, respectively, 'are engaged successively at the times inthecycle the'contacts CRI, BRI., and AR'I are closed. `It is seen that, under the "assumed-conditions, and due to the `connections ofthe described control circuits, yno

circuits are completed from vconductor |03 through Vthe closed contactsARI, BRI, and CRI, conductors |05, and contacts Ato the. pickupcoilsV of the relays URI I-to'URI-I, TRI to TRI'I,/HR| to HRII, RIS and conductor |04to'effect energization of vany of the said relays. Obviously, the only circuits whichcouldbe energizedunder the 4assumed conditions arecpen1 due to the operated 1, 2, and 5"contacts `A. Due to the arrangement of the verifying 'circuit'sthe numerical data values "are verified first, jafter which the 'verification'of the'colordesignations is effected, -upon the closing of'rcont-acts AR2, ARS, BR2, BR3, -CR2, CR3 and opening of contacts AR4., BRII, and yCR'4., circuits-are completed to effect energization `of'relays R20, R24., and R28. lOne of the circuits can betracedasfollows: conductorl, contacts vART-I, ABB and coil of relay R20 to conductor |04.

Holding circuitsfor the said relays are established immediately through the associated contacts -R20a, R2-4a,R-2a,which are connected bya-com- V'mon conductor |05 `to the 'normally closed cam contacts C6. Contacts'R20b,'R24b-and R28b are also closed to effect partial completion of the vcolor Verifying circuits-upon'closure offcam contacts C2. lHowever, since the 'colorvalu'es to be veried'are lin agreement. no circuits Vare 'completed bythe 'dommutator device when the brushes IIII'l thereof traverseY the f 11, 12, 13 and "14 conducting segments |00 associated with the Ycolor designat-V ing keys and contacts of the keyboards'ection, and corresponding control relays.

It should be stated-that the cam controlled contacts C| to C4 are closed successively (see Fig. 8) and in synchronism with the successive engagement of the brushes |0| and the 11, 12, 13, and 14 conducting segments |00. In this manner, the different color verifying circuits can be established. The purpose of this arrangement will be understood as the description progresses. Near the end of the machine cycle, the cam contacts C6 are opened and cam contacts C5 are v closed for the duration of onepoint vin the ma# chine cycle. Opening of contacts C6 breaks the holding circuits to relays R20, R24 and R28, thus restoring the said relays to the normal deenergized condition; and upon closure of contacts C5 the key release magnet 84 of the keyboard section is energized to release the data keys and themotor bar latchedin the depressed position. Release of the motor bar causes deenergization of the feed control magnet 44 due to the opening of'contacts 8|, thus preventing further record feeding operations until the motor bar is depressed again to close the said contacts 8 Now, assume that the data'values set up in the keyboard .section and the data recorded land sensed on one of the records are notin agreement. For example,l assume that the s'et up in the keyboard section represents the data V125, and that the color designations represented therein are red, whereas the data recorded on the said record is 126 and the colors of the data representing spots are blue. The motor bar is depressed and contacts 8| are closed as before to effect energization of the feed control magnet 44, thereby rendering the record feeding means and commutator device operative. Since the sensed data, namely 126, and verifying data, namely 125, are not in agree# ment the following circuitsv are established. lAt the time the spot in the 6 index point position in the units column on the record is sensed 'to effect energization of the relay AB, the brushV |0| is engaging the 6 conducting segment |00 which is connected to relays UR4, 'I R4- and HR4, and the associated 6 contacts A; and since the 6 contacts inthe units order of the keyboard section is closed, a circuit at this time is completed from conductor |03 to contacts ABI, conductor |05, "6 contact of the units order of the keyboard section, pickup coil of relay UR4, 6 conducting segment |0I1, brushes |0|, conducting ring |02, pickup coil of relay Rlgand conductorv |04, energizing the saidrelays UR4 and R|8. Holding circuits Vfor the said relays are established from conductor |03, contactsV |01j of a release key, contacts 1|, contacts UR4a, Rla, and related holding coils of relays UR4 Aand RIS, respectively, to conductor'v 04. The following circuit is alsoA established'from conductor |03 to the 6 indicating lamp l0 of the units order, contactsUR4l) to conductor |04, energizing said lamp and indicating that the number 6 sensed in .the units columnl on the record is in disagreement ,with the verifying data.

Continuing now withl the color veriiication, it is understood upon 4sensingV the blue data designation spots that the contacts ABZ, ABV4,YBB2, BB4, CB2, CB4 are closed and contacts ABS, BB3, andv CB3 are opened upon energization of the relays AB, BB, and CB, respectively, to establishcircuits to energize the relaysk-R2|,R25, and-R29 ofthe` group vof relays `R|9 to R30. Holding circuits are f established through the contacts R2la, R250L, R29a and the normally` closed cam contacts C6. Contacts R211), R251) and R201) are closed so that during thelatter part of the'cycle the color values of the data=can be verified. It is understood that at the timev in the cycle, when cam contacts C3 areclosed, the brush |0| engages conducting segment 13, and since the contacts A representing blue data designations are closed theA following circuits are completed, upon closure of cam contacts C3: conductor |03, contacts C3, contacts R2 Il), R251), R291), conductors |09, contacts A representing the blue data designations of all the orders of the keyboard section, pickup coils of relays HRIS, TRI 3 and URI3, conducting segment 13, brushes |0I, conducting ring |02; pickup coil of relay R|8 and conductor |04, energizing relays UR|3 to HR|3 (it is remembered in thepresent example relay RIB is energized and locked). Holding circuits for the said relays are established from conductor |03, contacts |31 of reset key RK, contacts 1|, contacts URISa, TRISa, HR|3a,fand related holding coils of relays UR|3 to HRIS, respectively, to conductor |04. The described holding circuits are maintained until contacts |01 or 1| yare opened. Upon energization 'of the said relays URI|3 to HRIS,` the l associated contacts URlSb to'lI-IRISZ) are closed to permit the associated indicating lamps to be energized, thus indicating that the blue data designation spots sensed in the units, tens and hundreds columns are in disagreement with theV Verifying data. i

Near the end of the cycle the cam contacts C6 are opened as Vmentioned hereinabove, to break the holding circuit for relays R21, R25 and R29 and restoring the said relays to the normal de! energized condition; Cam contacts C5 also are closed near the end of the cycle to effect energiza' tion of the magnet 84 and release thelatche'd data' keys and motorb'ar. Itis seen however, that this operation is not effected whenever relay R|8 is energized, since contacts Rld are open whenever disagreement of the sensed and verifying data occurs. i

' When n o disagreement exists' between the sensed and stored data, the feedl control magnet 44 is deenergized near the end of each cycle' by" virtue of the opening of contacts 8|. However,` it is vnoted inrcases of disagreement of the 'said data additional provision is made in the feed magnet circuit to deenergize the magnet 44 and pre` Vent further energization thereof bymean's ofthe opened contacts RISI).

Upon determination by the operator whether thevindicated -error exists in the sensed lm record or in the keyboard setup the error keyl EK or the release key RK is depressed. If an# error. was made in setting up the stored or verifying data the release key RKis depressed'to break the holdingv circuitfor the groups of relays 'URI 'to URM, TRl'to TRM, and HRI to HRM and relay R'IS, by'opening the contacts |01, thus restoring these circuits'to thenormal deenergized condition, whereby further verifying operations can be effected as described. i" A Upon'deefergization of relay RIB and continued depression of the release key RK'to maintain the contacts |01@ closed, a circuit is established from conductor |03 to contacts |01a, conductor |0311, contacts Rl8d, magnet 84 to conductor |04, energizing said magnet to effect releasing of the' depressed keys of the keyboard section.' y If the error exists in the sensed film record, th error key is depressed to energize the error mag- '75 net 68. Energization ofthe said magnet causes,

the said film record to bel notched as indicated in- Fig. 1 by the reference character 63.

Upon operation of the error'magnet` 68 the contacts 'II are opened to break the holding' circuits to the groups of relays URI to URM, TRI to TRM', and HRI to HRM and RI'8, thus restoring these energized circuits to the normal deenergized condition. Contacts 'Ilia are closed at this time to connect the conductor IIN)` to conductor I03a to effect energizationof magnet 84 upon closure of contacts RISCZ to cause the latched keys to be released. Contacts 'Ilay can be adjusted so that the' make period is sufcien-t to permit contacts R.I8d to close and' eiect energization ofthe said magnet IML` The machine is now conditioned for further verifying operations.

An additional feature of the present machine comprises the provision of means whereby' the film record can be analyzed to determine the presence of unwanted spots or imperfections in the spaces between the index point positions, which imperfections or spots would cause the statistical machines to function improperly, if not detected. To attain this, the brushes IDI of the commutator device are arranged so that the next adjacent segment is engaged thereby before disengagement of the first segment (see arrangement of conducting segments in timing chart). In this way the groups of relays URI to URIII, TRI to TRM, etc. can be energized at any time during the sensing portion of the cycle to indicate the presence of unwanted spots or imperfections in the nlm records. It is,y understood from the above description that the recorded data designations are eifective to operate certain ones of the` control relays AR to AB, BR to BB, and CR to CB whenever the said data designations are sensed. By means of the operated contacts` ARI to ABI, BRI to BBI, and CRI to CBI, which represent or in` dicate the data values of the sensed designations upon their operation, and the described commutator device 99 and the associated control circuits, the sensed data values are compared to the data stored or represented by the contacts A of the. keyboard section. Now, by providing the segments .IDU of the said commutator device to overlap the'next adjacent segment, as indicated in the timing chart, the brushes IBI engaging these segments: can complete circuits through diierent ones of the relays of the groups URI to URIU- HRI to HRW, depending upon the times at which the contacts ARI to ABI, etc. are operated. Thus, any unwanted marks or designations, capable of influencing the control operations of statistical machines, cause circuits to be completed through certain of the relays of the group ARI to URIIL, etc. to effect an indication of disagreement between the designations sensed on the records and the predetermined verifying data represented by the operated keys of the keyboard section as described hereinabove. The described control circuits are also effective to indicate any unwanted marks orY designations formed incolor byy causing certain of the relays URI I to URM, TRI I to TRIII, and HRII to HRM to be energized, whenever the unwanted colored designations are sensed, similarly as set forth hereinabove.
