Abstract: 1,225,973. Valves. JOSEPH LUCAS (INDUSTRIES) Ltd. 14 May, 1968 [16 Feb., 1967], No. 7503/67. Heading F2V. [Also in Division G3] A pressure regulator for the supply of gas or a breathing mixture comprises a first valve 13 connected by a U-shaped blade spring 34 to a diaphragm 28 responsive to the pressure in outlet 12 via hole 35, and a second valve 18a connected to a diaphragm 18 which is responsive to the pressure differential across the first valve. The valve 18a is biased into contact with a seat 17 by a spring 19 and a spring-loaded hollow piston 37 is biased into contact with the seat 20 of the first valve to prevent fluid from the inlet 11 passing to the first valve from the chamber below the diaphragm 18 which is connected to the inlet by passages (40), (41) in the housing. The regulator is made operative by pulling the piston 37 downwards by handle 39 to allow inlet fluid to pass through the open first valve which causes a pressure drop across the diaphragm 18 to open the second valve to connect the inlet directly to the outlet. As outlet pressure rises the first valve and thus the second valve move to the closed position, the valves again opening on outlet pressure decrease. Inlet pressure holds the piston 37 in the actuated position, but on failure of inlet pressure the piston will move to abut the seat 20 and render the regulator inoperative. On leakage through the valve causing excess outlet pressure, seat 25 will move away from valve 23a to vent the outlet to atmosphere at 36. In modifications, a passage through the valve member 18a may interconnect the chambers each side of diaphragm 18, the seat 17 may be formed with the knife edge, the valve member 18a being flat and the valve members 13 and 23a may be frustoconical and conical respectively.

Abstract: 1,251,832. Anit-skid control of fluid pressure brakes. AUTOMOTIVE PRODUCTS CO. Ltd. 14 Jan., 1969 [15 Jan., 1968], No. 2077/68. Heading F2F. [Also in Division G3] A control system for an anti-skid fluidpressure braking system for vehicles according to a first embodiment, Fig. 2, combines currents derived from first, second and third transducers P1, P2 and T, representative respectively of vehicle deceleration, I D , axle load or displacement, I A  and brake-fluid pressure, I P , with a bias current, I B , to control the release of the brakes by means of solenoid-operated relief valve B in series with antilock control valve A. The currents are summed at a junction S.J. so that for I P -I B +I A >I D , the input voltage to an operational amplifier A, is negative so that its output potential is positive and is therefore clamped to virtual earth (i.e. the potential of the junction S.J.) by a diode, D2, thus the relay coil R A  is de-energized to maintain the valve B as shown in Fig. 2 i.e. the brakes are released. However when the braking pressure falls so that I P -I B +I A <I D  the amplifier output potential goes negative, its potential being limited with respect to that of virtual earth point X, clamped by a diode D1, by resistor R6, which potential may be amplified at A2 to energize the coil R A  to arrest the release of braking fluid. In a second embodiment, Fig. 5, not shown, wheel speed only is measured by a tachogenerator (20) which supplies an alternative control circuit enabling brake release and re-application signals to be generated for one of three conditions according to the magnitude and phase sense of a reference voltage (Vc). The reference voltage is combined with a differentiated speed signal at a summing junction to control an operational amplifier and relief valve to arrest brake pressure release and hold the brake pressure substantially constant, until wheel speed equals vehicle speed when the brakes are reapplied. A further circuit, Fig. 6, not shown, permits the arrest of relief of braking pressure when wheel speed exceeds that at which deceleration ceased by 5 m.p.h., which time is indicated by a point 3 on the wheel speed curve (k/s) Fig. 4, (not shown), in which vehicle speed is represented by the chain-dot line (V s ). A summing junction (S.J.) receives currents representing instantaneous wheel speed, a wheel speed at which deceleration ceased and a reference current representing a speed difference of 5 m.p.h., the sum actuating a relief valve through an operational amplifier as in Fig. 2. The circuit is arranged to be inoperative when the wheel is not accelerating. Figs. 3a-3d, 7a, 7b, not shown, illustrate details of fluid-pressure valves.

Abstract: 1,258,392. Automatic optimizing control. ROLLS ROYCE Ltd. Dec. 23, 1968 [Dec. 29, 1967], No. 59029/69. Heading G3R. In a system for controlling a vehicle having two propulsion engines, one on each side of an axis of symmetry of the vehicle, closed-loop control systems maintain a predetermined speed and direction of travel and the fuel flows to the propulsion engines are perturbated in opposite senses and compared with the resulting acceleration of the vehicle to derive signals for adjusting the fuel flows in opposite senses to obtain maximum acceleration and hence minimum fuel supply. In Fig. 1, the speed of an aircraft is determined by a signal 106 which is compared with a signal 108 dependent on airspeed so that any difference is effective to adjust valves 114, 115 controlling the flow of fuel to port and starboard jet engines 102, 104. Sections 150, 170 of a digital computer derive ramp pulses from random binary sequences produced at 134 and apply them at 154, 174 to oscillate jet nozzles 164, 184 and/or other variables apart from the fuel supplies. Signals corresponding to the resulting variations in yaw acceleration as detected by an accelerometer 194 are applied to the computer which then produces signals 156, 176 which adjust the nozzles step by step until engine thrusts are a maximum. The heading of the aircraft is determined by a signal 120 which is compared with a signal 122 dependent on the heading so that any difference is effective to adjust rudder 130. A further section 190 of the computer derives ramp pulses from the random binary sequences produced at 134 and applies them at 196, 200 to oscillate fuel valves 114, 115 differentially. Signals corresponding to the resulting variations in forward acceleration as detected by an accelerometer 208 are applied to the computer which then produces signals 198, 202 which differentially adjust the fuel valves step by step until forward acceleration is a maximum.
