Title: Improvements relating to vacuum braking systems for railways
Inventor: MOORE IVAN GEOFFREY
IPC: B60T13/46
Filed: 1958-04-14
Abstract: 844,661. Vacuum brakes for railway vehicles. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 14, 1959 [April 14, 1958], No. 11742/58. Class 103 (1). An accelerator valve for the passenger-operable emergency mechanism of a railway vacuum braking system comprises a valve body 1 having a first port 2 for connection to the train pipe 3 and a second port 4 for connection to atmosphere, the interconnection of said ports being controlled by a check-valve 6 capable of being opened in response to a flexible diaphragm 8 subject opposingly to the degree of vacuum in chamber 21 connected via pipe 20 to the train pipe 3 and to the degree of vacuum in chamber 11 connected via passage 15 to a vacuum reservoir 10, a port 14 controlled by a valve member 16 movable by the flexing of the diaphragm 8 is normally in communication with the vacuum reservoir 10 and is connected to a magnet valve means 13 operable by movement of the driver's brake valve to a brake-applying position to open the vacuum reservoir 10 to the train pipe 3; the valve member 16 being movable by the flexing of the diaphragm 8 to close the port 14 when the train pipe vacuum is reduced. due to the operation of the passenger-operable mechanism. So that the driver can have proper control over brake applications by the operation of the driver's brake valve, the accelerator valve is rendered inoperative by a magnet valve 13 when the driver's brake valve (not shown), is moved away from its " running " position towards its " service application " position and thereby opens the vacuum reservoir 10 to the train pipe 3. However, once the check valve 6 has been opened by a reduction in vacuum in the train pipe 3 the valve member 16 closes port 14 and cuts off the connection between chamber 11 and magnet valve 13, thereby ensuring that the driver cannot over-ride the accelerated venting of the train pipe. A manually-operable release valve 17 (Fig. 2), in communication with the vacuum reservoir 10 is provided such that it cannot be operated until the train is stationary. The reservoir 10 is charged (i.e. evacuated) through pipe connection 15, chamber 11, and equalizing check valve 19, joined to the train pipe 3. A modification is disclosed in the Specification wherein a latch mechanism is provided to maintain the check valve 6 in the open position until the train has stopped so that the driver must descend from his cab to manually release the latch mechanism and release the brakes.

Abstract: 737,712. Automatic control systems for supply circuits of electric discharge tubes. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 27, 1954 [April 30, 1953], No. 12023/53. Class 38 (4). [Also in Group XL (c)] The electric supply to the cathode heater of a magnetron is automatically varied inversely to the mean input modulating power to the magnetron. The power fed to the magnetron circuit H, Fig. 1, from a pulse generator is proportional to the current through resistance R1 in the supply circuit to the pulse generator ; the resistance R1 is shunted by condenser C1 to provide a circuit having a long time constant, and a potential corresponding to the current is tapped from VR1 to control the heating current to the magnetron. To allow for variation of the potential of the D.C. supply to the pulse generator, the control knob is ganged to the tap on VR1. The control voltage from VR1 may be applied to the grids of alternately firing thyratrons V1, V2, Fig. 2, to vary the period during which each conducts and thus the average current delivered at H. In Fig. 3, the thyratrons V1<SP>1</SP>, V2<SP>1</SP> are biased from a separate transformer T3 over rectifiers D1, D2 and this bias is opposed by the control voltage.
