Abstract: 586,294. Fluid-pressure controlled brakes. WILD & CO., Ltd., M. B., and BATTY, A. W. H. Sept. 6, 1944, No. 17049. [Class 103 (i)] [Also in Group XXX] In a winding drum brake mechanism of the kind in which brakes co-operating with drums are applied by weights and released by hydraulic or pneumatic means, additional hydraulic or pneumatic means counteract in part the brake applying weights and are put into and out of action by valve mechanism. As shown the winding drums a are on a common shaft and clutching means (not shown) are provided so that both drums may rotate together or alternatively one drum may remain stationary while the other rotates. Brake shoes b are applied by weights c and are released by the action of hydraulic or pneumatic pistons d and cylinders e. The weights c are counteracted in part by cylinders n driving pistons m secured to the pistons d. The supply of fluid to the cylinders n is controlled by a valve s the setting of which is determined by the relative position of levers u, t which also operate respective isolating valves q controlling fluid supply to the cylinders e. In operation when the levers u, t are set to position the isolating valves q to supply fluid pressure to both the cylinders e, the valve s is set by a linkage y coupled to the levers u, t to supply fluid to the cylinders n. Normal control of the brakes is effected by the pistons d under the control of a valve p and lever v. When one drum is to remain stationary the respective lever u, t is manipulated to cut off pressure from the respective cylinder e and due to the linkage s this causes pressure to be cut off from both cylinders n so that the full force of the respective weight c is applied to the brake of the active drum The force exerted by either piston m may be half the corresponding weight c.

Abstract: 952,015. Gas-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. May 4, 1962 [June 15, 1961], No. 17176/62. Heading H2B. A gas-blast switch which may be similar to that described in Specification 885,932 has its high pressure chambers 13 connected to a high pressure tank 25 maintained between pressure limits by a temperature compensated pressure switch 42 controlling a compressor 36 which extracts gas from the low-pressure container 2. The tanks 25 are provided with valves 48 which open when the temperature in the tank falls and the consequent reduction in pressure operates the switch 42 so that the compressor operates to supply gas which is heated by the compression and raises the temperature in the tank 25 to reclose the valve 48. This is particularly applied to sulphur hexafluoride circuitbreakers in order to prevent the liquefaction of the gas. A heat exchanger 85 brings the low-pressure gas to ambient temperature and a heater 58 may be operated by a bi-metal switch 38 if the temperature is low. The valves 48 may be fitted in the chambers 13 (Fig. 2, not shown), or electromagnetic valves may be energized through bi-metal switches (Fig. 6, not shown).

Title: Improvements in remote angular position control systems
Inventor: LUDBROOK LESLIE CARTER
IPC: G05D3/12
Filed: 1956-06-07
Abstract: 817,332. Electric control systems. BRITISH THOMSON-HOUSTON CO. Ltd. Aug. 28, 1957 [June 7, 1956; Sept. 13, 1956], Nos. 17631/56 and 28022/56. Class 40 (1). An angular position control system comprises a. selsyn transmitter having a short-circuited single-phase rotor winding and a receiver the rotor of which carries an excited winding and a pick-up winding in space quadrature therewith, the excited winding being supplied through a resistor with single-phase A.C., and an error voltage induced into the pick-up winding being amplified and used to operate a servomotor which rotates the receiver rotor into a null position. As shown, the error voltage produced in the pick-up winding 7 on the receiver rotor, the magnitude and phase of which are determined by the angular divergence # between the shortcircuited transmitter rotor winding 2 and the excited winding 5 located on the receiver rotor 90 degrees apart from the pick-up winding 7, is amplified at 8 and fed to the control winding of a two-phase A..C. motor 9 coupled to the receiver rotor. Alternatively, a reversible D.C. motor may be used, in which case the amplifier 8 includes a phase-conscious rectifier. The value of a resistor 6 in the receiver rotor energizing circuit is high compared with the reactance of winding 5, to limit the current taken and to ensure that the error voltage is substantially in. quadrature with the A.C. supply. Equilibrium is reached every 90 degrees of #; alternate states are, however, unstable, according to the polarities chosen. To reduce the possibility of 180-degree ambiguity occurring, a permanent magnet 10 may be incorporated in the transmitter rotor to introduce a second harmonic component into the receiver voltage, which may be used to give warning of, or to inhibit, balance at the undesired position. The second harmonic voltage may be filtered off from the terminals of winding 5, or the pick-up winding 7 may be displaced slightly from its true quadrature relation with winding 5, the second harmonic voltage being taken from winding 7.
