Abstract: 922,497. Sparking-preventing in switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 26, 1961 [July 8, 1960], No. 23969/60. Class 38 (5).  A high-energy plasma device is used as a D.C. motor to provide a reverse voltage in series with circuit-breaker contacts at the instant of contact separation. As shown, contacts S1 are opened first to connect a plasma device, which may be as described in papers by W. R. Baker and others and K. Boyer and others at the second United Nations International Conference on the Peaceful Uses of Atomic Energy (Geneva 1958), in series with the circuit-breaker contacts S2. The field coil 2 of the device 1 is consequently energized in dependence on a time constant related to the values of its inductance and a parallel resistance R. A switch S3 is then closed to reduce the field and thus the current in the device 1 and the contacts S2 are opened at current zero. In an alternative arrangement (Fig. 1, not shown), the field winding is energized by the discharge of a capacitor fed from a separate supply.

Title: Temperature control system for electrical heating elements
IPC: F24C15/10
Filed: 1954-08-20
Abstract: 753,420. Automatic temperature control systems. GENERAL ELECTRIC CO. Aug. 20, 1954 [Aug. 21, 1953], No. 24311/54. Class 38 (4). In Fig. 4 a heating element 29 of a cooker hot-plate is of the metal sheath-helical resistance conductor type described in Specification 144,767, [Class 39 (iii)]. To detect variations in temperature of a cooking vessel (not shown) supported on the hotplate, thermistors 58, 59 having a high negative temperature coefficient of resistance are embedded in an aluminium button 56 which is mounted on a ring of lava 50 in the centre of the hotplate and maintained in thermal contact with the cooking vessel by a spring 57. Stainless steel heat shields 41 and 53 ensure that thermistors 58, 59 respond only to the temperature of the cooking vessel. A nickel-chrome heating resistor 60 is provided for biasing purposes. Movement of a manually operated control knob 71, Fig. 5, to any of the " Warm," "Boil," or " Fry " positions completes, through switches 91, 92, the supply from a single-phase source 111, 114 to rectifiers 186, 187 providing H.T. to a double triode valve 170. The unbalanced anode currents of this valve then operate a differential relay 190 to close contacts 198 so that a relay 205 is energized to switch on hot-plate heating element 29. Thermistors 58, 59 are combined with variable resistances 84, 85 to form a D.C. bridge circuit the output of which controls the grid potentials of valve 170 so that when the hot-plate reaches a temperature determined by the setting knob 71 the bridge balances and equalizes the anode currents of valve 170, thereby switching off heating element 29. The desired temperature is thereafter maintained by intermittent energization of heating element 29. When operating in the " Fry " range heater 60 is energized to reduce hunting. A preset potentiometer 200 provides a service adjustment facility. If, owing to a fault, the temperature of the hot-plate rises unduly the bridge circuit becomes unbalanced in the opposite sense and relay 190 then energizes the heater 212 of a solder pot to release a resettable circuit-breaker 210. Continuous energization of the hot-plate without automatic temperature control is possible by moving knob 71 to a [" Cut-out " position. Specification 661,675, 'Group XI], also is referred to.
