Title: Control apparatus for electric heating units
IPC: H05B1/02
Filed: 1950-03-15
Abstract: 675,539. Electrically-tripped switches. PROCTOR ELECTRIC CO. March 15, 1950. [March 17, 1949] No. 6476/50. Class 38 (v). [Also in Group XXXV] A control switch for an electric oven, which allows (1) normal operation with the heating resistors 1a, 1b in series under the control of a thermostat 18, (2) flash heating with the resistors in parallel, followed by normal operation under thermostatic control, and (3) automatic de-energization of another heater 3 during flash operation, comprises spring contact arms 5-7 normally biassed to the right (as seen in Figs. 1a and 9) and co-operating with fixed contacts 9-13, the contact arms being connected by an insulating tie bar 8 and movable to the left (for flash operation) by a cam 16 operated by a control knob 29 which also actuates cams 17, 23 and 27. The tie bar 8, when sufficiently moved to the left, is retained in the flash position by a latch bar 14 engaging the edge of a bimetal latch 15 which then (over contacts 7, 13) shunts the contacts 21, 22 of the thermostat. When the thermostat contacts open the full current through resistor 1b also passes through the bimetal latch 15, which quickly heats up and releases the latch bar 14 so that the tie bar 8 and its associated contact arms spring to the right (cam 16 being so shaped as to allow this) to terminate flashing and establish normal operation. Cams 17 and 27 work on contacts 5 and 26 to isolate the resistors 1a, 1b from the mains L1, L2 when the knob 29 is in the "off" position. Cam 23 controls the setting of the thermostat.

Title: Safety device for motor vehicles
IPC: B60Q5/00
Filed: 1936-03-04
Abstract: 451,646. Automatic safety controlling means for motor vehicles. WELT, A., Fasanenstrasse, Berlin, and GOMPERTZ, H., 8, Marienstrasse, Hanover, both in Germany. March 4, 1936, No. 6605. [Class 79 (v)] [See also Groups XXVII, XXXVII, and XXXVIII] When the driver releases a switch associated with the steering wheel of a motor vehicle an alarm is sounded, the ignition circuit is broken, and the fuel supply to the engine is cut off. A second switch is also provided which has three effective positions, viz.:- (1) the automatic control is operative, (2) the automatic control is inoperative, and (3) the ignition and fuel supply are interrupted, and the closing of the ordinary starting or ignition switch closes an alarm circuit and thus gives warning of the attempted unauthorized use of the vehicle. The second switch may be key-controlled. In the construction shown, switch contacts 4, 5 on the steering hand wheel 1 are separated when the driver releases his grip on a ring 6 below the wheel 1. When the contacts are held together the circuit of a relay coil 12 is completed from the battery 14 through the ordinary ignition switch 13, lead 15, contacts 16, 8 of a switch 9, lead 7, and contacts 5, 4 to earth. The relay armature 20 is raised from the position shown and an insulated strip thereon bridges contacts 23, 24, so that circuits are completed through lines 15, and S<1>, V<1> to the ignition coil S and a coil V which opens the fuel valve of the engine and working conditions are established for the engine. The magneto coil J is also made effective at the same time, as the armature 20 in moving away from a contact 22 breaks the earth connection which is shown made through the armature. When the driver releases the ring 6 the contacts 4, 5 separate, the relay 12 is de-energized, and the fuel supply is cut off and both ignition circuits put out of action. At the same time the armature 20 earths a contact 21 and completes a circuit for the horn H which is sounded until the contacts 4, 5 are brought together again. The switch 9 is rotated through 90‹ for each operation of a knob 11. In the position shown the safety device acts as stated. In the next position, the contact arm 10 bridges contacts 16, 17 and the relay 12 is continually energized independently of the switch 4, 5, so that the safety device is out of action. In the next two positions of switch 9, contacts 17, 18 or 18, 8 are bridged, but the relay 12 is not energized so that (1) the engine cannot be started and (2) the armature 20 completes a circuit for the horn H if the ignition switch 13 is closed, thus giving warning of any attempt to use the vehicle.
