Title: Rod and tube temperature sensor for controlling the heating means of an oven or the like
IPC: H01H3/24
Filed: 1967-03-06
Abstract: A thermal switch controlling the heat cleaning operation of an electric cooker in response to a rod and tube temperature sensitive element comprises a snap action switch assembly, Fig. 3, which is allowed to open when the end member 27 of the rod moves to the left as the temperature rises. The contacts 42, Fig. 6, of the switch are carried by a forked member 32 pivoting about lugs 38 engaging slots in the switch casing. A lever member 48 is pivoted to the switch casing by lugs 50, and its free end is connected to the contact member 32 by springs 55. The operating temperature can be adjusted by a screw 53. Leaf spring switches 29, 30 are normally held closed by plungers 61, 62 engaging lever 48, but are released when the snap action switch opens. The fixed contacts of switches 29, 30 are adjustable. The cooling operations are controlled by a second rod and tube element operating a snap action switch similar to that just described through a fluid pressure transmission, Fig. 5, comprising a bellows 82 and a chamber 112 having a flexible wall carrying a stud 113 operating the switch. The operating temperature of the switch is adjusted by a knob 103 moving the chamber 112 and stud 113 towards or away from the switch. The spindle of knob 103 carries a cam actuating limit switches through toggles 133, 137. A flexible capsule 91 is arranged to compensate for ambient temperature variations. A single rod and tube element may be arranged to actuate switches in the cooking, heat cleaning and warming circuits of the oven. The end member 211 of the rod, Fig. 10, of the temperature senser operates a switch 234 through a fluid pressure transmission as described in connection with Fig. 5. A knob 114 sets the operating temperature for switch 234 and operates switch toggles 144, 148. A snap action switch 212 similar to that shown in Figs. 3 and 6 is operated by an adjustable pin 222 at the lower end of a lever 215 pivoted to the end part 211 of the temperature senser rod. The upper end of lever 215 carries an insulating block 221 arranged to allow leaf spring switches 213, 214 to open when the temperature rises. In another embodiment, the setting of a thermal switch is controlled from a remote knob by fluid pressure transmission, the movable end of the temperature senser rod carrying a fluid chamber with a flexible wall to which the switch actuating stud is secured. In this embodiment additional switches are operated by a lever pivoted to the cooker frame and secured at one end to the end of the temperature senser rod.

Title: Improvements in or relating to hydrostatic steering systems, particularly for motor vehicles
IPC: B62D5/32
Filed: 1967-07-29
Abstract: In a hydrostatic or telemotor steering system comprising a twin-output control pump 3 driven by a steering-wheel 1 and acting as a proportioning means, and a device which includes a pair of control valves 4, 5 and is operated in dependence on the movements of the steering wheel to control the direction of fluid flow from a servo-pump 8, two hydraulic circuits are supplied by the control pump 3 and each circuit comprises the two control valves and a servomotor 6, 7. As shown, each circuit is controlled by one-half of the control pump 3 and by both control valves 4, 5. On rotating the steering-wheel 1 clockwise firstly the ring gear of the epicyclic gear train 2 moves the valve spools 40, 50 of the valves 4, 5 to the right and left to determine the direction of fluid flow and secondly the sun-wheel of the gear train 2 rotates the control pump 3 which accepts from lines 13, 18 high-pressure fluid which is supplied from the servo-pump 8 through grooves 411 and 42 and through a groove 511, bore 551 in the valve spool 501 and grooves 541, 54 and directs it to the servomotors 7 and 6, respectively, through a line 17, grooves 52, 521 and a line 19 and through a line 14, grooves 44 and 431 and a line 16. Exhaust fluid from the servomotors is returned to a reservoir 9 through the control valves 4, 5 and lines 12. Should one of the lines 15, 16, 19, 20 break a respective valve may be operated manually to return the fluid being supplied to the broken line to a line 12 and the reservoir 9. Due to the reduction in pressure at the respective outlet of the control pump 3 the pump tends to act as a motor thereby indicating the breakage to a driver. In the neutral position of the steering wheel the control pump 3 blocks communication between the control valves 4, 5 holding the servomotors stationary. A valve 10 permits operation of the steering system manually should the pump 8 be inoperative.

Title: Transistorized vertical deflection circuit
IPC: H03K4/71
Filed: 1972-10-31
Abstract: Transistorized vertical deflection circuit employs output stage of class B, push-pull, complementary symmetry configuration. Miller integration approach is used for sawtooth wave generation, with feedback waveform derived from yoke current sampling resistor. Diode, coupled between ground and base of the (NPN) output transistor which conducts during retrace and first half of scan, operates in Zener region during retrace to hold voltage at joined emitters of output pair at s substantially constant voltage during retrace output waveform is thereby stabilized against effects of B+ changes due to line voltage variations or loading extremes, and remaining (PNP) output transistor dissipation is held substantially constant in the face of such changes. Diode in feedback path, forward biased when retrace ends, ensures rapid turn-on of driver stage when discharge transistor cuts off oppositely poled diode in shunt with first feedback diode completes low impedance capacitor discharge path during retrace. One winding half of vertical deflection yoke is shunted by a capacitor of a value selected to introduce cancellation of horizontal frequency components across yoke/pincushion circuitry, in order to minimize feedback of interlace-disturbing horizontal components in deflection circuit.
