Abstract

1,212,780. Automatic flushing of lavatories. TATEISI ELECTRONICS CO. Nov. 19, 1968 [Nov. 27, 1967], No. 54864/68. Heading G1N. An automatic water supply system includes a Colpitts oscillator 10 and a capacitive proximity sensor 12. In operation, approach of a user damps the oscillations so that a direct voltage step appears at terminal a which step turns-off a transistor Tr<SP>4</SP>, to produce a signal (So) to a delay timer, 44, which signal is distinguished from those caused by casual passers-by by its persistence, and thence causes operation of a flushing valve 58. A monostable multi-vibrator 48 controls the duration of the flushing period. Upon withdrawal of the user, the signal (So) disappears, activating a NOT element 50 which causes the valve 58 to be operated again via differentiator 50, multi-vibrator 54 and amplifier 56. A compensating circuit 32 feeds back part of the rectified oscillator voltage to a vavactor diode CV thereby maintaining the potential at a constant for slow ambient charges (e.g. humidity). In operation the signal (So) turns-on a transistor Tr5 after a delay set by C3, R4 thereby energizing a relay RY which opens a contact S1 to render the compensating circuit inoperative. Simultaneously contacts S2, S3 are charged to activate a timer circuit 36 which turns off the transistor Tr5 after a time determined by a monostable multi-vibrator 40, thus effectively resetting the system. Thus if a user provides a continuous signal by leaving a bag (say) in the vicinity of the sensor its presence is nullified by operation of (the timer circuit). Slight circuit modifications are given in Figs. 2, 3 (not shown) whilst Figs. 4, 5 (not shown) illustrates lavatory basins incorporating the system.
