Patent GB-498267-A (GB)
Abstract: 498,267. Voting-apparatus. KULCSAR, J. Dec. 8, 1937, No. 33955. [Class 106 (iv)] The apparatus is energized before the registration of each vote by the closing of contacts 13 upon the depression of a control button 12 by an official. The voter then closes one of a series of switches 5. A corresponding vote counter 14 and a grand counter 16 are thus advanced and the contacts 13 opened even though the control button is held depressed. The control button 12 closes the contacts 13 through toggle levers 35, the contacts being held by a latch 40 on an armature 38 urged to the left by a spring. When a vote has been registered, a releasing electromagnet 29 is energized to attract the armature 38 and so release the contacts 13 and break the toggle. When the control button is depressed, signals 18, 32 operate. The voters' switches 5 are closed by plungers, a crowding lock in the form of a flexible tape preventing more than one plunger being depressed at any one time. The circuit of the releasing magnet 29 is completed at contacts 25, 28 when any counter 14 and the grand counter 16 are actuated. The apparatus is stated to be portable.

Abstract: 1482678 Telegraphy; D.C. systems SIEMENS AG 20 Nov 1974 [4 Dec 1973] 50220/74 Heading H4P A switching circuit for establishing several different current values between a pair of conductors comprises a plurality n (where n is an integer #2) mechanical or electronic switches S1-S4 arranged serially and alternately with n - 1 diodes D1-D3 mutually unidirectionally poled whereby one pole of each diode is connected via a separate resistor, e.g. R1 to one conductor and the other pole also via separate resistors, e.g. R2 to the other conductor i.e. there being 2 (n - 1) resistors. With such arrangement 2<SP>n</SP> different current values are possible with n switches with unidirectional polarity across the conductors or if the polarity is reversible 2<SP>(n+1)</SP> current values can be obtained. Alternatively polarity dependent electronic switches may be used hence allowing (2n+1) values. Such polarity dependent switches may be poled to conduct current in the same direction as the diode. The circuit may be employed in remote switching devices of teleprinter or data transmission systems, in which case a diode bridge (DB) (see Fig. 4, not shown) may be employed to avoid polarity dependence. In this arrangement four resistance values are possible (including infinity) by utilizing two switches, two resistors and a diode. Electrical isolation (not shown) may be incorporated in the circuit. Other arrangements employing either mechanical switches and/or transistors are envisaged in the Specification.

Abstract: 1,030,830. Automatic control. VAPOR CORPORATION. April 9, 1964 [May 28,1963], No. 50578/65. Divided out of 1030810. Heading G3R. [Also in Division G1] A device for detecting the cooling effect of a gas stream comprises temperature sensing means in the form of a mercury containing bulb 11 communicating with a capillary tube 12, the bulb 11 being mounted in a conduit 10 in the gas stream, a resistance coil 25 surrounding the bulb to supply heat thereto at a constant rate, a first electrical conductor 14 on the tube 12 normally in contact with the mercury therein, a second electrical conductor 16 for contact with the mercury at a preselected temperature of the bulb and a circuit including a signal lamp 20 which will be lit when the cooling effect of the gas stream falls to a predetermined level. As the coil 25 supplies heat at a constant rate to the bulb 11 if the temperature of the gas stream rises or if the flow rate decreases then the bulb temperature will rise and eventually complete the lamp circuit. A further conductor 21 is provided on the tube 12, so that if the cooling effect still continues to fall, an electromagnet 23 will be energized to open a switch 27 in the heater coil circuit thus preventing damage to the device. The device may be used to control the cooling effect of the gas stream. In Fig. 2 an item 28 is cooled by air from a conduit 43 containing a device 45 similar to that shown in Fig. 1. Air from a conduit 32 passes either along a conduit 35 or through a cooler 38 the relative proportions being controlled by a valve 36. The device 45 has six contacts such as those indicated by 16 in Fig. 1 and these are connected to an indicator 48 calibrated in suitable units. The indicator 48 may also control the valve 36 to maintain the cooling effect of the gas stream at a selected valve.

In a solid state converter (Fig. 2) for conversion in either sense, additional commutation reactance is provided, when operating as a rectifier, by inductors 45, 46, 47 each having a reactance X R . When operating as an inverter, switches 35, 36, 37 are closed thus shorting these inductors so that the circuit commutation reactance comprises the A.C. supply system reactance indicated by inductances 13, 14, 15 each having a reactance X s  and the leakage reactance of the transformer only indicated by inductances 31, 32, 33 each having a reactance X L2  A master control unit 22 controls all the converters in the system, supplying information to respective bridge control units 23 as to firing angle for required output and mode of operation. The bridge control sends gating pulses to the valves 25-30 (each of which may be a plurality of SCR s) in dependence upon instantaneous phase voltages sensed by transformer 24. The master control 22 also actuates a relay 38 which operates a switch unit 40 via a switch trigger unit 40 to close the switches for inverting operation. The switches will not close however unless the trigger unit 39 also receives synchronizing signals from current transformers 43 or from the potential transformer 24 depending on whether voltage or current disturbances, which could cause commutation failure, predominate in a particular converter circuit. Voltage disturbances are more of a problem in inverters. The switches may be closed sequentially at zero current instants in the respective phases, and may have a jet of plasma injected between the mechanical contacts thereof at the instant of opening or closing.
