Title: Improvements in or relating to electromagnetically operated electric switches
IPC: H01H1/02
Filed: 1938-12-16
Abstract: 522,798. Electromagnetic switches. STANDARD TELEPHONES & CABLES, Ltd. Dec. 16, 1938, No. 36705. Convention date, March 29.

Patent GB-889927-A (GB)
Title: Improvements relating to electrical remote control systems for the operation of devices such as pumps
Inventor: DOBSON JOHN THOMAS
IPC: G08C19/12
Filed: 1959-10-29
Abstract: 889,927. Electric-selective signalling systems. EVERSHED & VIGNOLES Ltd. Oct. 27, 1960 [Oct. 29, 1959], No. 36780/59. Class 40 (1). In a remote control system in order to prevent a field station effecting any operations in response to spurious pulses the control station normally transmits a guard frequency which renders every field station inoperative. As described in a first embodiment a central station 1, Fig. 1, controls one field station 2. Normally a device IT at the central station transmits a guard frequency which energizes a relay 1R at the field station, opening a contact 1R1 which prevents a relay B being energized which, in turn, prevents two control relays 2R and 3R being energized. In order to effect a control the central station must as a preliminary, cease to transmit the guard frequency and transmit a single D.C. pulse by momentarily closing a contact S2. This ceases, respectively, the closure of contact 1R1 and the energization of a relay A, the latter causing the energization, and subsequent holding, of the relay B. The actual control is then effected by one of two transmitters 2T, 3T transmitting a distinctive frequency which causes one of two relays 2R, 3R to respond at the field station. As shown the field station also includes a device 7 which transmits an amplitude significant D.C. voltage to a meter 8 at the control station. In a second embodiment, Fig. 2, each of the relays 2R and 3R is associated with ten relays Y1-Y10 and X1 to X10 respectively, which each effect different controls, and the particular pair of relays X and Y which are to be controlled by relays 3R and 2R is selected by means of a dial P at the control station. Thus in operation the guard frequency is normally transmitted and the field station is non-responsive. To select a particular pair of relays X and Y the appropriate number of D.C. pulses are dialled (the guard frequency still being transmitted) which causes a switch TS at the field station and a switch RS at the control station to advance. Bank RS1, at the control station operates a lamp to indicate the digit dialled. Nothing further occurs until the guard frequency is removed and the single D.C. pulse is transmitted by the control station. This causes a switch TC to advance at the field station until its position coincides with that of switch TS and in so doing it produces pulses which advance a switch RC at the control station. When the position of switch TC at the field station coincides with that of switch TS, the position of switch RC should coincide with that of switch RS and if it does a confirmatory lamp 22 at the control station is energized. The desired control can then be effected by either of the transmitters 2T and 3T. The re-application of the guard frequency causes the homing of the various switches. Specifications 806,514 and 806,515 are referred to.

Abstract: 449,404. Knitting. TAYLOR & CO. (HUCKNALL), Ltd., S., HINCKLIEFF, A. E., and FORD, H. P., King Edward Street, Hucknall, Nottinghamshire. Dec. 24, 1934, No. 36929. [Class 74 (ii)] For making pelerine work in a circular knitting- machine, some of the sinkers or web-holders 12 are provided with cranked offset nebs 14, as shown in Figs. 2 and 3. These sinkers co-operate with adjacent sinkers 17 of a more ordinary character. When a plain stitch is required on a given needle, the sinkers 12, 17 on either side of that needle are retracted and the yarn is fed over the nebs 13, 18 but when a pelerine stitch is required the sinker 12 is projected and the yarn is fed over the upper neb 14. The corresponding needle thus draws a longer loop and, by retracting the sinker 12, this loop 20, Fig. 11, is expanded and brought over the adjacent needle 19. The sinker 17 is projected to trap the pelerine loop between its neb 21 and the crank 15 of the sinker 12 and the two sinkers 12, 17 are retracted together to keep the pelerine loop over the needle to which it is to be transferred, as the needle rises. Fig. 5 shows a sinker for use where the pattern calls for a vertical line of ordinary stitches. Specification 410,810 is referred to.

Abstract: 1324476 Starting I.C. engines BENDIX CORP 16 Aug 1971 [14 Sept 1970] 38382/71 Heading H2H [Also in Division H3] A control circuit for the starting system of an internal combustion engine comprises a mechanical switch 10 having "OFF", "ON" and "START" positions, a first electronic switch 30 for controlling current flow between the mechanical switch and a solenoid 5 which controls the energization of a starting motor, and a second electronic switch 20 for controlling the state of the first electronic switch, the arrangement being such that after an initial energization of the solenoid by placing the mechanical switch in the "START" position, the starting motor cannot be re-energized until the mechanical switch has been moved to its "OFF" position for a predetermined time. When the switch 10 is moved from its "ON" position in which a capacitor 19 is charged from a source 1 to its "START" position, transistors 32, 34 are turned on to enable energization of the solenoid 5. The switch 10 is then returned to its "ON" position so that the collapse of the magnetic field of the solenoid 5 switches on a thyristor 22 thereby turning off the transistors 32, 34. If a second attempt is now made to start the engine by returning the switch 10 to its "START" position the thyristor, since it is still conductive, prevents the switching on of the transistor 34 thus preventing the energization of the solenoid. However, if the switch 10 is placed in its "OFF" position the capacitor 19 discharges through the thyristor until the thyristor is turned off at the end of the predetermined time. The switch 30 is therefore returned to its "ON" state to enable the energization of the solenoid 5 when the switch 10 is placed in the "START" position. Reference has been directed by the comptroller to Specification 1,201,889.
