Abstract: 1,243,886. Distributers. NORTH AMERICAN ROCKWELL CORP. 25 July, 1969 [7 Aug., 1968], No. 37603/69. Heading H4P. A multiplexer which has two groups of input terminals 0-7, 8-15 and two output terminals 28, 29 is operable in two modes. In one mode (mode 1), the input signals on terminals 0-7 are passed successively to terminal 28 and then those on 8-15 successively to terminal 29, and in the other mode (mode 2) signals on one terminal in both groups are simultaneously passed to their respective output terminals, followed by other pairs of signals in succession. Clock pulses at terminal 17 step a binary counter comprising bi-stables 30, 40, 60, 70 whose first three stages feed a gating circuit 50. The last stage feeds a circuit 90 which, dependent on the mode selection signal at terminal 36, generates signals X, Y successively (mode 1) or simultaneously (mode 2). The gating circuit 50 receives #X, #Y and generates signals on its outputs a-p which control the multiplexing of the signals in the selected mode. Lamps 38 indicate the state of the counter, and a signal appears at 49 at the end of a scanning cycle. If an enabling signal (logic 1) is not present at terminal 35, or if there is a clear/reset signal at terminal 19, a circuit 100 resets the counter to zero. The counter can be set to a selected count, after being reset to zero, by a Read signal at terminal 18. The counter is then set to a count determined by signals on the counter terminals SET Q1-SET Q4, counting continuing from this point when the Read signal ceases.

Abstract: 355,622. Fluid - actuated valves. TYLORS (WATER & SANITARY), Ltd., and JONES, A., Belle Isle, York Road, Holloway, London. Dec. 17, 1930, No. 37992. [Class 135.] Valves controlled by pilot or relay valves.-A flushing valve for closets comprises a piston-operated lift valve 7 closed by fluid pressure acting above the piston 8 and having access through a passage 16 controlled by a screw 17. To obtain the flush an auxiliary tilting flush starter valve 14, disposed on or within the main valve 7, is tilted to open position by a handle 25, 41 operating through a hollow spring-pressed sliding plunger 22; the pressure above the piston 8 is thus relieved to the discharge pipe 3 and the valve is lifted and opened by the fluid pressure in the inlet passage 2. When the sliding tubular extension 28 of the starter valve spindle lifts above the opening plunger 22 the starter valve falls back to its closed position and the main valve begins to move downwards and finally closes. The depending tubular extension 28 is adapted to telescope on the spindle 15 whereby any attempt to keep the starter valve open, and thus obtain an unlimited flush, by holding down the handle 41, is counteracted. The rate of flow of the water during the flush is expedited by air admitted to the discharge passage 3 through the vent opening 30 in the handle 41 and the hollow plunger 22.

Abstract: 1479343 Transistor solenoid actuating circuits; amplifiers REGIE NATIONALE DES USINES RENAULT 3 Sept 1974 [5 Sept 1973] 38562/74 Heading H3T A circuit for energizing a solenoid comprises a voltage and current amplifier feeding the solenoid and a switching circuit for selectively feeding three reference voltages to the input corresponding respectively to a stand-by current, a peak energizing current and a holding current. The voltage being raised from its stand-by level to its peak energizing level linearly by integrating a fourth reference voltage. The solenoid 9, e.g. of a fuel injector of an internal combustion engine, is fed by a common-emitter Darlington pair 6, 7 which is itself fed by an inverted Darlington pair 1, 2. A voltage U 4  proportional to the solenoid current is applied to the emitter of transistor 1 so that differences between a control voltage U e  and U 4  cause a change in the collector current of 6 and 7 to keep the difference very small. During stand-by there is no input on 101, transistor 20 is off and 21 on, so transistors 18 and 16 are on. The control voltage at 100 is therefore determined by Zener diode 11 to be (R 4 .Ip) where Ip is the stand-by current through solenoid 9. Energization is initiated by applying a voltage Ti to the input 101. The differentiator circuit 24, 25 turns transistor 22 on for a time 2#. While it is on, the constant voltage produced by Zener diode 26 is integrated by amplifier 27 and capacitor 29 to provide a ramp signal at point 102. The voltage U 4  is compared with the ramp by comparator 30 and when it is below the ramp comparator 30 gives a positive output which applies the voltage (R 4 .Im) determined by Zener diode 12 to control point 100 (where Im is the peak energization current of the solenoid). The ramp signal thus controls the rate at which the solenoid current reaches Im. Holding phase.-At the end of time 2#, transistors 22 and 23 turn off and the solenoid current falls freely from the peak. The control voltage at 100 cannot fall below (R 4 .Id) corresponding to the holding current because ever since input Ti was applied transistor 18 has been off and 19 on. Consequently 17 is on and hence the minimum voltage at 100 is determined by Zener diode 13. De-energization.-When Ti is removed from input 101, transistor 19 turns off, but capacitor 32 prevents transistor 18 turning on immediately so the current in the solenoid falls to zero. When capacitor 32 has charged sufficiently, transistors 18 and 16 turn on and the stand-by condition is restored.
