Title: Electrical remote control system
IPC: G05D3/14
Filed: 1946-02-06
Abstract: 647,943. Control of D.C. motors. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. Feb. 6, 1946, No. 3800. Convention date, April 10, 1945. [Class 38(iii)] [Also in Group XXXVIII] In a system in which the reversible motor driving a directional aerial may be controlled, at will, to run continuously, or to operate under the control of an electric follow-up system involving interconnected potentiometers, or' to impart to the aerial a continuous scanning movement about the point selected by the followup system, it is arranged that the potentiometers are mechanically disconnected from the motor and the control handle respectively while the motor is set to run continuously. The electrical system therefore remains balanced in readiness for the switch-over to follow-up control. With the ganged switches S1, S2, S3, S4 in position III, an A.C. voltage, adjustable in amplitude and reversible in phase is derived at potentiometer 34 and is applied to a device 10 which preferably comprises a pair of grid-controlled rectifiers, arranged as described in Specification 647,580, and produces a reversible direct current in the field winding 14 of a Ward-Leonard generator feeding the aerial driving motor 5. With the switches in position II the input side of the device 10 is connected to the receiving potentiometer P2 of the follow-up system and the sliders of the potentiometers P1, P2 are clutched respectively to the control handle 50 and to a shaft coupled by an electrical synchronous control or otherwise to the driving motor. At the same time, the sending potentiometer is connected to the A.C. source in place of potentiometer 34. In position I of the switches, the motor remains under the control of the follow-up system but the output of the latter is supplemented by a voltage derived from a potentiometer 52 via reversing contacts of relay 55. Consequently the balance point is shifted to one side or the other of the point selected by the control handle. When the new balance point is reached, the reversing relay changes over and shifts the balance point to the other side of the manually selected point and this action is repeated. In a further embodiment, Fig. 2, not shown, the system is carried by a 'vehicle and the receiving potentiometer is controlled jointly by the driving motor and by a gyro to compensate for yawing movements of the vehicle.

Title: Improvements relating to fluid pressure control apparatus
Inventor: SHATTOCK CHARLES FREDERICK BAI
IPC: B61H9/00
Filed: 1962-02-01
Abstract: 1,006,942. Fluid pressure systems for brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 21, 1963 [Feb. 1, 1962], No. 3860/62. Heading F2F. A fluid-pressure system for rail vehicle brakes comprises two control valves A, B, a setting valve means SVA, SVB connected to the control valves, the setting valve means controlling the actuation of a changeover valve CV for supplying fluid to a brake cylinder BC on the operation of either of the control valves. In the construction shown the setting valve means consists in two valves SVA, SVB each valve including two chambers 6, 7 separated by a diaphragm 3 and connected through a throttle 8. The diaphragm carries stems 4, 5 which co-operate with spring-loaded valves 9, 10 when a pressure difference is created across the diaphragm. Each fluid output from the valves SVA, SVB communicates with a chamber 17A, 17B of a piston 17 of the changeover valve CV, each chamber possessing a venting port 11, 12. On actuation of the control valve A fluid enters chamber 6 of valve SVA to move the diaphragm and stem 5 to open valve 10 which allows fluid to flow from line MR through a chamber 16 to chamber 17A to hold piston 17 on a diaphragm and its associated changeover stem in the position shown in the drawing. Fluid enters the brake cylinder BC through lines AO and 18A. Pressure in chambers 6, 7 will equalize slowly through the throttle 8 whence the diaphragm will return to its equilibrium position. If a higher braking pressure is introduced into the line AO the valve SVA will operate again to keep piston 17 in its actuating position. On release of the brake pressure the diaphragm and associated stems 4, 5 will move in the opposite direction to that above to maintain the changeover valve in the correct position. If the control valve B is operated, valve SVB is actuated to allow fluid to pass to the chamber 17B of the changeover valve CV such that the piston 17 and valve stem 18 are moved to connect the line BO to the brake cylinder BC. The venting channels 11, 12 may be uncovered only at the end of the piston or diaphragm stroke. The changeover valve device may also be provided with detents to retain it in one or other of its extreme positions when fluid pressure is released from it.
