Title: Bistable storage elements

Filed: 1971-12-30
Abstract: 1379408 FET data storage circuits SIEMENS AG 30 Dec 1971 [5 Feb 1971] 60810/71 Heading H3T [Also in Division H1] A bi-stable has F.E.T.'s 11, 15, with capacitor loads 12, 16, cross-coupled by voltage-dependent resistors such as F.E.T.'s 13, 17; and input/ output F.E.T.'s 5, 6. Read-write bit lines and the F.E.T.'s 4, 6 charge and discharge C12, C16  so that for example C16 is positively charged, C12 is discharged. When a pulse power supply makes terminal 2 positive relatively to 1 and p-channel F.E.T.'s are used, F.E.T. 15 is held off by the positive potential on C16 applied through F.E.T. 17 which has been turned on thereby. The potentials at 112 (U1, Fig. 2, not shown), rises to a proportion of the pulse power amplitudes (U) determined by the potential divider formed by C12 and the circuit capacitances between 112 and 2. F.E.T. 13 is then turned on (by U1) and applies this potential (U1) to F.E.T. 11 gate to turn it on. Thus C14, C16 are kept charged by the pulse power supply, the state of the circuit being reversed only by fresh inputs from 7, 8.

Patent GB-783876-A (GB)
Abstract: 783,876. Calculating-apparatus. BURROUGHS CORPORATION. Feb. 24,1956, No. 5841/56. Class 106 (1). Aligning mechanism for the differential actuators of a calculating machine is adapted to move the actuators back slightly from their differential stop positions and then to hold them against further advance until cyclically operated means has restored them. The invention is applied to the machine described in Specification 783,869 which comprises actuators 31 moved forwardly (to the left) to differential stop positions when released to the action of springs (not shown) upon forward cyclic movement of a restoring bar 32. A set of aligning rack bars 96 are pivotally carried on a shaft 97 between arms 98 of a yoke pivoted on a shaft 100. A crank arm 114, Fig. 6, secured to the yoke is normally held by a spring 119 against a stop 117 which maintains the bars 96 inactive against the under surface of a fixed plate 105 and clear of co-operating pawls 112 secured to the actuators 31. The crank arm 114 is engaged and rocked clockwise by the bar 32 towards the end of its forward movement and after the actuators have reached their stop positions. The consequent downward movement of the shaft 97 causes the rack bars 96 first to rock downwardly into engagement with the actuator pawls 112, under the action of individual springs 109, and then to move the bars rearwardly slightly. This rearward movement is imparted to the actuators, as they are brought into aligned positions slightly rearward of the stop positions, and releases the pressure of the actuators on, for example, the totalizer wheels in a total-taking operation to permit easy disengagement. A latch 122 engages over a stud 123 on the arm 114 to hold it in its forward limit position with the rack bars 96 engaged during return rearward movement of the bar 32, the pawls 112 ratcheting over the teeth of the rack bars 96 as they are restored by the bar 32. When the bar 32 finally reaches its rearward home position, it trips the latch 122 so that the spring 119 restores the arm 114 to disengage the rack bars 96.

Patent GB-2036186-A (GB)
Title: Gas powered motors and vehicles powered thereby
IPC: F01K25/10
Filed: 1979-08-31
Abstract: A gas powered motor (33) has a reservoir (28) for liquefied gas, a supply passage from the reservoir leading through one side of a heat exchanger (29) to the motor and a container (52) holding a buffer substance in heat conductive relationship with the reservoir. The buffer substance acts to supply heat to the liquefied gas whilst undergoing a chemical, physical crystallographic or other change of state to assist in maintaining the supply of gas to the motor (33) from the reservoir (28). In order to preserve the gas supplied to the motor for re-use without the need of a container of substantial volume the motor exhaust leads to a vessel (36) containing a condensing buffer substance (37) which condenses the gas by adsorbing, persorbing or otherwise associating with the gas accompanied by a release of heat. The condensing buffer substance is in heat conductive relation with the other side of the heat exchanger (29) in the gas supply to the motor to superheat the gas supplied. The condensing buffer substance is capable of releasing the gas when subjected to reduced pressure by a pump (50) provided which may be the gas motor (33) run in reverse to extract the gas from the vessel (36) and return it to the reservoir (28). In another embodiment the condensing buffer substance comprises an isothermal heat sink provided, for example, by a concentrated salt solution. <IMAGE>

Title: Braking system for the control of fail-safe brakes
IPC: B60T13/18
Filed: 1979-10-08
Abstract: A braking system for the control of a fail-safe brake 16, particularly for use on a trailer, includes a source 10 of pressurised fluid connected with a braking effect control valve 12 which is in turn connected via conduits 14a, 14, 15 with first 23 and second 26 fluid pressure operated actuators so that both actuators are subject to an equal level of fluid pressure from the valve 12 at all times. A spacing 30 is provided to apply the brake 16 in the absence of a brake releasing force. The first actuator 23 is arranged to generate a brake releasing force to render the spring 30 ineffective to apply the brake at conduit pressures at and above a first level thus allowing release of the brake. The second actuator 26 is arranged to apply the brake at conduit pressures above a second higher level. The control valve 12 is arranged on activation of the system to raise the pressure in the conduits to a level between the first and second levels to release the brake, and, on receipt of a braking command input signal Y, to raise the pressure in the conduits to a level above the second level proportional to the value of the braking command input signal thus applying the brake. An alternative construction in which the first and second actuators are combined into a single compound actuator 40 (Fig. 2, not shown) is also disclosed. <IMAGE>
