Title: Controls for Overcenter Motor-Pump Unit
IPC: F16H61/46
Filed: 1968-08-01
Abstract: 1,198,014. Hydrostatic transmissions. GENERAL SIGNAL CORP. 1 Aug., 1968 [7 Aug., 1967], No. 36723/68. Heading F2D. A swash plate unit 1 operates alternatively as a pump and a motor to transmit energy back and forth between a flywheel 3 and a pressure compensated system 2, e.g. a hydrostatic transmission including a pump and motor (not further described), movement of the plate 7 being automatically controlled by motor assemblies 12, 14 in response to systems pressure 4. When the pump in system 2 can satisfy the flow demand from its motor, systems pressure rises above a predetermined value, e.g. 3050 p.s.i. for a system compensated to 3200 p.s.i., and unit 1 acts as a motor to drive flywheel. However, when the flow demand exceeds the pump capacity, the pressure 4 falls below a second predetermined value, e.g. 3000 p.s.i. and the unit 1 functions as a pump driven by the flywheel 3. When systems pressure 4 is between these values, unit 1 is in neutral. Control.-A one-way flow control valve 31 limits the rate of flow to unit 1 to prevent overspeeding of unit 1 and flywheel 3 during motoring. The unit 1 operates as a fixed displacement motor or a variable-displacement pump. The motors 12, 14 are controlled by valves 15, 24 which connect them to systems pressure 4a or exhaust 5, and which are controlled by a servomotor 22, systems pressure, and a spring 29. The servomotor 22 is controlled by a valve 23 which connects the motor to systems pressure on exhaust. Valve 23 opens at pressures above 3050 p.s.i. to energize motor 22 to shift valves 15, 24 to the left against spring 29 to vent motor 12 and biasing means 11 and energize motor 14 to move the swashplate 7 to its maximum motoring position with unit 1 driving the flywheel. When the pressure falls below 3050 p.s.i., valve 23 closes, venting motor 22, and allowing valve 15 to move to the right to supply pressure to motor 12. If the pressure is between 3000 and 3050 p.s.i., systems pressure holds valve 24 to the left maintaining motor 14 actuated, and the swashplate assumes a neutral position. When the pressure falls below 3000 p.s.i., valve 24 is moved to the right by spring 29 to vent motor 14 and allow unit 1 to be driven as a pump by flywheel 3. A one-way brake 10 or a delay valve prevents reverse rotation of flywheel 3 on start-up.

Title: Electronic timepieces
IPC: G04G9/12
Filed: 1976-09-06
Abstract: 1521409 Electronic timepieces DAINI SEIKOSHA KK 6 Sept 1976 36841/76 Heading G3T [Also in Division G5] In an electronic timepiece with an electrooptical display device (e.g. liquid crystal) for displaying various time information, the colour of the display is determined by the pulse duty ratio of alternating drive voltage selectively applied to the display device, the colour indicating the nature of the time information displayed. The timepiece may incorporate an alarm (e.g. buzzer or Piezo-electric sound producer) and the pre-set alarm time may be selectively displayed. In Fig. 1, the 1 Hz output of a frequency divider 2 steps seconds, minutes and hours counters 3, 4, 5. Times at which an alarm is to operate are pre-set in a memory circuit 6 comprising mins and hours counters. The mins and hours BCD signals from counters 4, 5 and the memory circuit 6 are fed to a coincidence circuit 8, comprising Ex OR gates and NOR gates (not shown), and upon coincidence a circuit 9 is actuated to operate an alarm. Each time a function selecting switch SW 1  is closed, a pulse from a latching circuit 15 advances the logic "1" output of a ring counter RT to the next stage, the outputs of RT providing control signals Ï 1 -Ï 4 . These signals are used to control a display driving voltage selecting circuit 18 which combines various outputs from the f-divider 2 to provide different display drive voltage waveforms. The signals Ï 2 , Ï 3 , Ï 4  are also used to control a switching circuit 7 to apply either the contents of counters 4, 5 or of the memory circuit 6 to a decoder 11. The decimal segment electrode output signals of the decoder are applied to AND gates in segment drive circuit 13 via Ex-OR gates, in a circuit 12. The Ex-OR gates and an AND gate 16 connected to the display common electrode, also receive output signal N of the divider in order to provide alternating voltage drive G-F(a), Fig. 2 (not shown) for the display device 14. The state of the control signals Ï 1 -Ï 4  controlling AND gates A 1 -A 4 , determines the output waveform of the voltage selector circuit 18 which in turn determines the duty ratio of alternating voltage pulses applied across liquid crystal material between selected segments and the common electrode, without change in amplitude (e.g. 10 V) of the applied voltage. The displayer device 14 is a mixed crystal device of the DAP (Deformation of Vertically Aligned Phases) type, wherein a colour change is obtained by change of the double refraction characteristics resulting from a change in direction of crystal molecules.

Title: Manufacture of porous diaphragms
Inventor: MELLISH STUART FREDERICK
IPC: C25B13/00
Filed: 1965-08-31
Abstract: A porous diaphragm of P.T.F.E. suitable for use in electrolytic cells is obtained by mixing a solid particulate additive substantially uniformly into an aqueous dispersion of polytetrafluoroethylene, coagulating the dispersion, forming the coagulum into a sheet and removing the additive.  Additives which suitably have a particle size in the range approximately 5-30 m  include for example starch or calcium carbonate, which are removed by soaking the sheet in hydrochloric acid, or a plastic polymer which may be dissolved out by an organic solvent or hydrolysed or depolymerized and vaporized by heating.  A particulate inorganic filler or particle diameter not greater than 1 m  may also be added to the aqueous dispersion before coagulation and this is not removed from the diaphragm sheet. Suitable fillers include barium sulphate, titanium dioxide and the amphibole and serpentine forms of asbestos and these are used in the range 40 to 70% calculated on the weight of polytetrafluoroethylene. In a preferred process the dispersion may be coagulated by adding electrolyte or a water-miscible organic solvent, e.g. acetone, the coagulum separated from supernatant liquor by filtration, the coagulum dried (hot air oven at 110 DEG  C.), mixed to a stiff paste with a high-boiling hydrocarbon, e.g. petroleum ether b.p. 100-120 DEG  C., made into a sheet by passing through rolls, additive removed and any filler retained.

Abstract: 1364476 Anti-skid braking systems AISIN SEIKI KK 9 Aug 1971 [9 Aug 1970 10 Sept 1970 (2) 16 Sept 1970] 37242/71 Heading F2F A digital type anti-skid braking system includes a sensor 15 producing a pulse signal representing the rotational speed of a wheel or the sum of speeds of different wheels, means for counting the numbers of pulses in signals produced in two time periods and subtracting the number of pulses in the second period from that produced in the first period to obtain the difference which is compared with a predetermined value, the braking pressure being relieved in response to the result of the comparison. The means for counting comprises an addition counter 71, a subtraction counter 72, and a register 74 and a control circuit therefor includes a clock-pulse oscillator 67 operating a counter 68 the binary outputs of which are connected to a control decoder 69 which in each cycle of operation first sets the addition and subtraction counters to zero and opens a gate 77 to allow pulses from sensor 15 to be counted by counter 71, the gate remaining open until it is closed by a pulse from the control decoder 69 at the end of the first time period. The decoder 69 then opens the gate circuit 73 to transfer the count in counter 71 to the subtraction counter 72 after which the gate 73 closes; the gate 76 is then opened and remains open until it is closed at the end of the second time period by the control decoder and the number then in the subtraction counter which is the difference between the two counts is transferred into the register 74 by a set signal from the control decoder; a comparison decoder 78 of a circuit 80 then compares the difference number with a predetermined number and if the number fed into the register is positive indicating wheel deceleration and greater than the predetermined number a latch circuit 79 is operated which applies a signal to a power amplifier 81 which in turn operates a modulator 17 to relieve braking pressure on the wheel. If the number fed into the register is negative indicating wheel acceleration the latch circuit 79 is caused to de-energize the power amplifier to cause braking pressure to be restored if it has already been relieved. If the difference number in the register is positive but lower than the predetermined number the previous state of the modulator remains unchanged. As shown in Fig. 11 a modulator comprises an hydraulic cylinder 31 of which a plunger 37 is connected to the diaphragm 45 of a vacuumsuspended servomotor the operation of which is controlled by an electromagnetically operated valve 30 whose operating coil 57 is energized by the power amplifier to allow atmospheric air to enter a chamber 50 to move the diaphragm against a spring 46 and allow a ball 43 to be pressed on its seat by a spring 42 to cut off the fluid from a master cylinder 12 the movement of the plunger 37 also increasing the volume of a chamber 36 to relieve braking pressure. Vacuum is provided by a connection to the engine intake manifold, a screw 56 providing adjustment of flow rate.
