Title: An automatic water supply system
IPC: H03B5/12
Filed: 1968-11-19
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.

Title: Arrangement for producing electrical pulses from a dc input
IPC: H02M3/337
Filed: 1971-11-26
Abstract: 1362038 D.O.-D.C. converters TELEFONAKTIEBOLAGET L M ERICSSON 26 Nov 1971 [27 Nov 1970] 55108/71 Heading H2F [Also in Division G3] A blocking oscillator produces trigger signals to control the frequency of a D.C. chopper, and controls an integrator which produces a sawtooth signal to determine the width of the chopped pulses in accordance with a predetermined reference. In the circuit shown, a D.C. input U 1  is chopped by power transistors 1, 4 driven by a multivibrator including transistors 2, 3. An output is taken from a transformer winding 20b in the form of square pulses which are rectified, 13, 14, and smoothed, 25, 43. The resulting D.C. output U 2  is compared with a Zener diode 19, and excess voltage turns on a transistor 8 to deliver an error voltage U s  to a blocking oscillator BO. A pulse output U 4  from the blocking oscillator determines the frequency of the multivibrator by producing signals on a winding 22a which terminate the chopped periods. The pulse width is determined by a sawtooth voltage of the same frequency as the signals U 4  and generated by an integrating circuit 17, 26, 27, 36. The resulting waveform is added to the error voltage U 8  to form a bias voltage U 6  which holds a transistor 6 blocked until a threshold voltage is reached. During this delay time, transistor 5 conducts so that a winding 21d is short-circuited and energizing voltages U a , U c  on windings 21a, 21c are inhibited so that both power transistors 1, 4 remain blocked. When the sawtooth voltage has reached threshold value, transistor 5 is turned off and the appropriate power transistor switches on to begin the next chopped pulse. The smoothed output voltage U 2  is thus regulated to a value determined by the Zener diode 19. In further embodiments, capacitors may be connected across the power transistors 1, 4, Fig. 4b (not shown), or four bridge-connected power transistors may be used, Fig. 4c (not shown).
