Title: Improvements in or relating to electrical remote control systems or the like
IPC: H02J13/00
Filed: 1927-12-06
Abstract: 307,443. General Electric Co., Ltd., and Clark, H. C. Hannam-. Dec. 6, 1927. Selective distant control systems. - In a system for the selective control and supervision of apparatus at a remote station of the type described in Specification 282,858 wherein a selective signal sent from the control station to the remote station is repeated back to the control station and an operation at the remote station dependent upon the selection is automatically performed only if the signal received corresponds to that sent out, the selective operations of the synchronously operated switches at the control and remote stations are effected by direct current impulses through the intermediary of equivalent alternating current impulses in the line circuit. The line wires may also be employed as power or telephone .lines. Figs. 1 and 2 show the apparatus at the control and remote stations respectively. Relays 56, 74, 73, 79, 57 at the control station and relays 502, 531, 530, 518, 506 at the remote station function in a manner corresponding to similar relays described in Specification 282,858. Thus operation of the selective switches at each station is effected by a system of reciprocal impulse control wherein operation of relay 57 transmits an impulse to energize relay 502 which through the intermediary of relay 506 operates relay 56 over line wires 1, 2 to bring about the transmission of another impulse by relay 57. At each operation of the relay 57 a source of alternating current 303 is coupled to the line circuit 1, 2 through transformers 304, 308, a line balance 309 being provided to ensure that alternating current is not applied to the circuit 310, 311. The alternating current impulses transmitted by relay 57 are applied through a filter circuit 410, 411 to an amplifying valve 419 the plate circuit of which is tuned to the frequency of the source 303 by the circuit 423, 424 and is coupled to a rectifying valve 425. The valve 425 controls the operation of a relay 429 which impulses the direct current circuit 430, 431 including relay 502. At the substation a source of alternating current 403 having a frequency which differs from that of the generator 303 is coupled to the line wires and is controlled by the relay 506 consequent upon operation of relay 502 to transmit alternating current impulses over the line wires to operate relay 329 through rectifying and amplifying valves 325, 319 and filter circuit 310, 311 and thereby control the direct current relay 56. In the normal operation of the system, a selective signal sent from the control station is followed by a signal reverted from the substation and checking the selection. If the correct checking signal is received stepping switches CS, IS occupy similar positions and relays 73, 530 are operated to energize, relays 74, 531 and cause operation of the selected apparatus unit. Synchronization of the stepping switches is effected by relays 79, 518 in a; manner similar to that described in the previously mentioned Specification.

Title: Improvements relating to vehicle hydraulic brake control valve means
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/26
Filed: 1966-07-23
Abstract: 1,211,201. Fluid pressure brakes; brake indicators. GIRLING Ltd. 23 Oct., 1967 [23 July, 1966], No. 33230/66. Addition to 1,079,505. Heading F2E and F2F. A control unit for an anti-skid braking system comprises an inertia controlled valve for insertion between a master cylinder and wheel cylinders, a differential piston operating in a stepped bore connected in parallel with the inertia valve and a by-pass valve also in parallel with the inertia valve. As shown in Fig. 2, fluid from the master cylinder enters the valve at 54 and passes via passages 40, 38 and lines 39, 51 to the front brake cylinders. Fluid from the master cylinder can also pass via a deceleration valve 30, and passages 34, 37 to the rear brake cylinders. A further passage between master cylinder and rear brake cylinders is available via the normally-open by-pass valve 44 and the passages 54, 40, 38, 39, 51, 50, 37. When the master cylinder pressure acting on the left hand side of a differential piston 41 is sufficient to overcome the force of springs 42, 43, the piston 41 is deflected to the right, so that spigot 52 allows spring 49 to close the by-pass ball valve 47. When the deceleration is sufficiently great, ball 30 moves to the left, closing the second path between master cylinder and rear brakes. Pressure from the master cylinder now acts on the right hand side of differential piston 41, so that the rate of increase in pressure on rear brake cylinders is less than that on the front brake cylinders. The valve may be inclined rearwardly so that the ball 30 is out of contact with the seating 33 or may be formed with an inclined lower surface to chamber 31. Fig. 3 (not shown) relates to an alternative arrangement in which the by-pass is formed by a passage (66) through the differential piston (41), the by-pass valve (63) being closed when the differential piston 41 is deflected by master cylinder pressure. Brake indicators.-A port 35 is provided for connection of a stop light switch. Fig. 1 shows an alternative by-pass valve in which the head 20 is normally biased away from the seating 22 by a spring 21, permitting flow of fluid from the master cylinder to the rear brakes via ports 25 and 26. When the pressure becomes sufficient to displace piston 18 to the left, valve 20 is closed so that the only communication between master cylinder and rear brakes is via a deceleration responsive valve and a pressure regulating piston in block 13.

Title: Flashing lamp circuits
IPC: H05B37/02
Filed: 1971-07-17
Abstract: 1399097 Lamp failure alarms CAV Ltd 11 July 1972 [17 July 1971] 33692/71 Heading G4N [Also in Division H3] In a lamp flasher circuit of the kind in which the lamp 15 is switched on by a relay 12 energized when a capacitor C becomes charged to a predetermined voltage, means are provided for sensing the current through the lamp and maintaining the relay energized in the event of failure of the lamp. Closure of switch 16 illuminates warning lamp 17, and allows capacitor C to charge through resistor R4, Fig. 1, until the voltage across it is sufficient to turn on T1 and energize relay 12. Contacts 14 then close to extinguish lamp 17, and illuminate lamps 15. Capacitor C now discharges until T1 turns off and the cycle recommences cuasing warning lamp 17 and lamps 15 to flash alternately. Under normal conditions, closure of contacts 14 will turn off transistor T2, but if one or more of lamps 16 fail, the change in current through resistor R5 changes the bias conditions of transistor T2 such that it does not turn off. T2 nows provides a hold current for relay 12 and warning lamp 17 is extinguished. In a modification, Fig. 2, the transistor T1 is replaced by a Darlington pair T3 which is protected against break down by Zener ZD 1 and against reverse voltages by diode D4. Transistor T4 maintains lamp 17 extinguished during the time the contacts 14 are closed, its base voltage being compensated by Zener ZD2 against variation of lamp current with supply voltage. D6 compensates the base-emitter voltage of T4 for temperature variations, and D5, D7 protect if for reverse voltages.

Abstract: 466,798. Weighing-apparatus. FAIRBANKS & CO., E. & T., HADLEY, H. A., and GULDBRANDSEN, G. Dec. 5, 1935, No. 33696. [Class 143] Printed records, apparatus for giving.-An automatic dial scale having printing mechanism for recording the weight and comprising weight value selector means, recording operating mechanism, means for transmitting the weight value set up by the weight value selector means to the recording operating mechanism and printing mechansim, is characterized in that a single rotatable control cam which is operated independently of the mechanism of the recording scale is adapted in a single revolution to effect successively the entire operations of weight value selecting, weight value transmitting, printing and recording. The spindle of the indicating pointer I, Fig. 1, carries four stepped discs 8 .. 11, Fig. 6, which are rotated with the pointer to a position representing the load. A stepped segment 13 coaxial with the stepped discs is set angularly by a mechanical connection with capacity weights used for increasing the weighing range of the machine. Selector fingers 25, 27 operated from a single cam 45, Fig. 2, by means of corresponding type-bar operatinglevers50pivotedon a shaft 48a are slidable in an horizontal direction to engage the stepped discs and segment. The lower ends of the levers 50 actuate sliding type bars 84 to present the appropriate type 97 above a printing hammer 119. One of the levers 50 also controls the engagement of a finger 26 with a toothed disc 12 on the pointer shaft to justify the stepped. discs prior to printing. In obtaining a printed record of the load, the operator actuates a push button thereby energizing a motor M and coupling-up a one-revolution clutch on the cam-shaft 46. During the rotation, the cam 45 effects the following movements, viz. (1) permits the levers 50 to rock in clockwise direction under spring influence, causing the feeler 26 to justify the pointer shaft and the feelers 25, 27 gradually to move up to the stepped discs 8 .. 11 and segment 13, thereby setting the type bars 84, (2) depresses a printing hammer control arm 126 to engage a cocking dog 135 with a pin 136 on the printing hammer 119 and thus cock the hammer, (3) displaces a feed ribbon arm 161 to feed the ink ribbon 141, and (4) rocks a lever 104 thereby effecting an alignment of the type bars 84 by means of an aligning dog 100 and causing a rod 140 to trip the cocking dog 135 thus allowing the hammer to move under spring action and print a record on an inserted ticket or sheet of paper. The ink ribbon may be rewound after unwinding by rotation of a handle 151.
