Abstract: 1,216,726. Fluid-pressure servomotor systems. WHESSOE Ltd. Sept.25, 1969 [Oct.16, 1968], No.48975/68. Heading G3P. [Also in Division F2] An angularly movable valve 2 allows liquid to flow through a drop pipe 12 into a vessel at a limited rate until the rise of the liquid level blocks the lower end of a passage 17 to cause means 8 to reduce the pressure in a pneumatic operating chamber 11 and release a locking device 4 which allows the valve to be moved to the fully open position by the liquid pressure differential thereacross. The means 8 may be a Venturi and the locking device a pair of links loaded by a spring 21 and displaced to the position shown in broken lines by a pressure responsive diaphragm 9 acting through a spring-loaded lever 10 and a plunger 19 mounted in an adjustable nut 6. The lower end of the passage 17 may be closed by a float or by the liquid itself. A flap 16 enables the flow through the valve in the closed position to be adjusted. In a further embodiment, a plunger actuated by the diaphragm locks a quadrant which may be mounted on the valve spindle or connected to it by links. A coiled spring closes the valve when flow ceases.

Title: Signal handling system for minimizing dropout effect
IPC: H04B14/00
Filed: 1974-11-12
Abstract: 1486021 Digital recording SONY CORP 12 Nov 1974 [20 Nov 1973] 48977/74 Headings G4H and G4C In a signal handling system, each of a parallel plurality of pulse signal inputs is switched to successive ones of an equal plurality of outputs at the rate at which input signals arrive. As disclosed, successive samples of an analogue waveform are digitized, each digitized sample being recorded in bit-parallel form on magnetic tape with subsequent read-out and conversion back to analogue form. A drop-out bit is assumed to be equal to the bit of the same weight in the preceding or succeeding digitized sample, and to prevent this bit also being a drop-out, the bits of a sample are cyclically permuted before recording, progressively more from sample to sample, so that bits of the same weight in adjacent samples are recorded in different tracks on the tape, and a reverse permutation is performed after read-out. The permutations are performed by gates enabled by shift registers in which timing pulses progress driven by clock pulses. A timing pulse track may be provided on the tape, or each track may be recorded in self-clocking form (using a transition at the centre of each "1" bit cell and between each two adjacent "0" bit cells), conversion to and from this form being performed after the initial permutation and before the reverse permutation.

Title: Improvements in or relating to variable-ratio hydraulic transmissions, more particularly for motor vehicles
Inventor: PAUL PANHARD
IPC: F04B7/04
Filed: 1963-12-13
Abstract: 1,063,942. Hydrostatic transmissions. SOC. ANON. DES ANCIENS ETABLISSEMENTS PANHARD & LEVASSOR. Dec. 13, 1963 [Dec. 15, 1962], No. 49445/63. Heading F2C and F2D. In a hydrostatic transmission having a constant displacement reciprocating piston pump 78 which supplies liquid through a non- return valve 80 and reversing valve 73 to a constant displacement motor 11, a hydropneumatic accumulator 88 is provided between the pump 78 and non-return valve 80 so that during the delivery stroke of the pump piston 77 liquid is initially supplied to the accumulator until the pressure of gas trapped above the accumulator piston 89 equals the pressure downstream of the valve 80, whereafter the remaining pump displacement is supplied past the valve 80 to the motor 11. The effective displacement of the pump past the valve 80 is thus automatically varied in response to changes in pressure downstream of the valve 80. The effective displacement of the pump is also varied in response to engine condition by varying the initial gas pressure above the accumulator piston 89. The chamber 83 above the piston 89 is normally closed by a spring-pressed valve 91 but is opened whenever the piston 89 reaches its lowest position by a tie-rod 92 to permit adjustment of the initial gas pressure in the chamber 83. As shown, the initial gas pressure is adjusted in response to engine inlet depression which acts against a spring 98 through a piston 97 and lever 99 on a valve spool told which supplies or exhausts pressure liquid to or from the right-hand side of a piston 104, the left-hand side of which communicates with the chamber 83 through valve 91. In Fig. 2 (not shown), the valve spool is in addition acted upon by pressure liquid supplied by an engine-driven pump in opposition to pressure exerted thereon by the accelerator pedal. A second accumulator 12 smooths flow to the motor 11. In Fig. 3 (not shown), two pumps having interconnected pistons are arranged in parallel to supply the motor 11. Fig. 4 (not shown) is a graph of maximum pressures attained in the chamber 83 and useful work done by the pump against transmission ratio for an adiabatic compression of the gas in the chamber 83.
