Title: Automatic temperature control systems
IPC: G05D23/275
Filed: 1960-12-05
Abstract: 907,345. Automatic temperature control systems. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 5, 1960 [Jan. 15, 1960], No. 41751/60. Class 38 (4). A temperature control system for a heating unit 10 comprises a main cycling switch 16 controlling the average wattage delivered to the unit, and a second cycling switch 33 which is responsive to the temperature of a vessel 11 heated by the unit 10 and which controls, over a circuit 31 energized from a transformer 32, a heating element 23 associated with a bimetal 17 of the switch 16, the arrangement being such that the switch 33 increases the heat output of element 23 upon increase in temperature of the vessel 11 and the switch 16 operates in response to such increase in heat to decrease the average wattage to the unit 10 until an equilibrium point is reached. The desired temperature is set by positioning a manually-operated knob 13 associated with cams 14, 29 and 45 acting respectively upon line contacts 15 which are open in the " off " position, main cycling switch contacts 21, 22, and control circuit contacts 46 which are also open in the " off " position. The control circuit may include a potentiometer 43 for varying the instantaneous wattage applied to the element 23. The switch 33 comprises control contacts 41, 42 in series with the element 23, a bimetallic element 34 attached to a metal element 35 which can engage the vessel 11 to sense the temperature thereof, a bimetal 37 carrying a heating element 38, and a bimetal 39 carrying the contact 41. Energization of the heater 38 causes bimetal 37 to heat and deflect in contact opening direction, whereupon the control circuit opens and bimetal 37 cools and then deflects in the contact closing direction. The contacts 41, 42 are thus cyclically opened and closed. Specification 805,410 is referred to.

Title: Anti-skid control device
IPC: B60T8/90
Filed: 1971-09-08
Abstract: 1337158 Anti-skid devices ALFRED TEVES GmbH 8 Sept 1971 [16 Sept 1970] 41833/71 Heading F2F In a dual circuit brake anti-skid device, an hydraulically actuated separating valve, controlled by a signal from a sensor, interrupts fluid communication between each wheel cylinder and its corresponding master cylinder, and in each line to the wheel cylinder there is a connection to a common cylinder bore on either side of a floating piston, a chamber of each line being allowed to expand in the bore by controlled movement of a separating piston, associated with the floating piston and having a stepped profile corresponding to an identical profile of the bore. Fig. 1 shows the device in a position whereby fluid passes from a tandem master cylinder 29 through lines 1, 2 and 1<SP>1</SP>, 2<SP>1</SP> to wheel cylinders 30, 30<SP>1</SP> respectively, the separating valves, 4, 4<SP>1</SP> controlled by electromagnetic valves 15, 16, being open. Valve 15 is closed to stop fluid from an accumulator 32 from operating the valves 4, 4<SP>1</SP>, and the valve 16 is open to a reservoir 31. An actuating piston 20 abuts the separating piston 10 which in turn abuts the floating piston 7 by fluid pressure from the accumulator 32. Upon wheel skid, a signal closes valve 16 and opens valve 15, thereby closing the separating valves 4, 4<SP>1</SP>. Simultaneously pressure fluid from the accumulator 32 enters a chamber 11 between the separating piston 10 and the cylinder bore to push the piston downwardly. This causes proportional movement in the floating piston 7 to allow the fluid in the lines 2, 2<SP>1</SP> to reduce pressure on the wheel cylinders 30, 30<SP>1</SP> by volume expansion at the chambers 8, 9. The actuating piston 20 and the separating piston 10 may be integral. Fig. 3 shows a two part separating piston 35, 37 to avoid foaming due to negative pressures in the chambers 8, 9 of the system is being checked when braking does not occur. During braking, the inner part 37 of the separating piston moves down with the outer part 35, if skidding occurs, by brake fluid pressure at its upper face. However during checking, if the actuating piston and the outer part 35 move down, an opening 36 in the outer part prohibits movement of the inner part 37 which obviates negative pressures in the chambers 8, 9.
