Patent GB-990575-A (GB)
Title: Electric switch
IPC: H01H5/06
Filed: 1961-05-11
Abstract: 990,575. Thermal switches; actuation of switches. M. CLAUSEN, [trading as DANFOSS VED. ING. M. CLAUSEN]. May 11, 1961 [May 11, 1960], No. 17271/61. Heading H2B. A snap-action switch having an over-centre tension spring 3 connecting an operating lever 1, pivoted at 2, to a contact-actuating arm 6, pivoted at 7, has an adjustable stop carried on the lever 1 to provide positive actuation of the arm 6 and to act as a back stop limiting the contact gap. The moving contact 9 is carried on a blade spring 8 biased to the closed position wherein contact 9 engages a fixed contact 11. Spring 3 is capable of overcoming spring 8, however, such that the positions shown in Figs. 1 and 4 are stable. Arm 6 engages blade 8 with lost motion by virtue of the turned-over end 13. A tongue 12 on arm 6 is positioned to reduce contact bounce and oscillation of blade 8. In a first embodiment (Fig. 1) the adjustable stop comprises a screw 18 while in the second embodiment (Fig. 4) a lever 15 is pivoted at 14 on lever 1 such that a nose 16 engages the arm 6 in the contacts-open condition while the other end of lever 15 engages an adjusting screw 17 mounted in the switch housing. The switch is operated by a force P which may be provided by an evaporator thermostat, for example. Since in the contacts-closed condition (Figs. 2 and 5, not shown) the spring 3 does not pass below pivot 2, the mechanism tends to restore to the conditions shown. The arrangement is such that if the force P is completely removed a much larger contact gap than normal results.

Abstract: 1461516 Tandem master cylinders GIRLING Ltd 4 April 1975 [19 April 1974] 17347/74 Heading F2F The interconnection between the main and secondary pistons 3, 5 of a tandem master cylinder includes a stem 19 having a head 20 slidable in a sleeve 13 whose end-wall 16 serves as an abutment limiting axial separation of the pistons. Assembly is effected by passing head 20 through a circular opening 17 in sleeve 13 (see Fig. 2) with the piston axes at right angles, then bringing the pistons in line so that stem 19 passes through a slot 16 in the sleeve. The stem may project forwardly from piston 3 or, as shown, rearwardly from piston 5. Sleeve 13 is screwed to a spigot 31 on piston 3 and the threads are subsequently deformed to prevent unscrewing. The pistons are urged apart by springs 24.

Abstract: 750,620. Fluid-actuated valves. INDUSTRIAL CONTROL VALVES, Ltd. June 21, 1954 [June 24, 1953], No. 17478/53. Class 135. In a pressure regulating valve comprising a body 1 having inlet and outlet passages 2, 3 and a closure member 5 connected to a diaphragm 7 (or a piston), subjected on one face through a passage 8 to outlet pressure and on its other face to the loading of a spring 10 abutting a plate 11, the spring loading may be automatically varied on movement of the plate 11 by electromagnetic or fluid-operable means. As shown, the plate 11 has a pin 13 which bears against the movable core 14 of a solenoid 15 mounted within a spring-loaded cylinder 16 slidable in the body 1. Adjustable stops 17, 18 co-operate with the core and cylinder respectively to limit the minimum and maximum spring loadings. When the solenoid is excited, the plate 11 is moved into the position shown, the spring 10 then exerting its maximum pressure. When no current passes through the solenoid, the plate 11, pin 13 and core 14 are moved upwards by springs 12 until arrested by the stop 17 and the spring 10 then exerts its minimum pressure. The fluid controlled by the valve may be, e.g., liquid or gaseous fuel or air supplied to the combustion chamber of a furnace, and the excitation of the solenoid may be controlled by a switch operable by, e.g., a thermostatic device responsive to combustion chamber temperature or to the pressure of the fluid in the inlet passage 2. The solenoid may be replaced by a fluidpressure servomotor responsive to either of the variable conditions mentioned, or by an electric motor which moves the plate 11 through a cam, screw, &c.

Title: Improvements in and relating to electric valve converting systems for energizing a load circuit through a capacitance
IPC: H02M1/02
Filed: 1942-12-14
Abstract: 563,531. Supply and control systems for resistance welding &c. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1942, No. 17729. Convention date, Dec. 18, 1941. [Class 38 (iv)] Thermionic control.-A welding or other load circuit is supplied with impulses of energy derived from an A.C. circuit through a capacitance which is discharged alternately through each of two primary windings of a transformer to avoid cumulative unidirectional magnetization of its core. A condenser 8 is charged through polyphase connected valves 15 ... 17 until the potential developed at a tapping 21 on a potential divider 20 overcomes the potential applied by a circuit 19 to the grids of the valves. Valves such as ignitions 33, 34 are connected between the condenser 8 and like windings 4, 5 of the transformer 3 supplying the welding circuit 1. Control valves 38, 39 are selectively ignited by impulses applied to transformers 47, 50 through valves 48, 51 energized by D.C. from a condenser 45 when timing impulses are applied to a transformer 55, but a commutating condenser 53 associated with an unbalancing condenser 58 ensures that successive impulses render alternate valves 48, 51 conducting so that the condenser 8 is discharged in turn through the windings 4, 5. Single impulses may be obtained from a condenser 60 by closing a switch 68 whereby a relay 64 controlling the charging and discharging of this condenser is operated and whereby the simultaneous charging of condenser 8 is prevented -by application of negative potential to the control grids of valves 15 ... 17 at contact 75 of relay 70. A series of timed impulses may be applied to transformer 55 by closing a switch 90. This couples a timing valve 86, which conducts intermittently at intervals rendered substantially equal to the time taken for condenser 8 to charge and discharge, and determined by the setting of a resistance 92 ; these periods may be synchronized with the supply circuit voltage by means of peaking impulses injected into the grid circuit of the valve 86 by transformer 93 through phase adjusting means 95, the condenser 8 being prevented from charging during each discharge by a rectified voltage injected into a condenser 115 in the grid circuit of valves 15 ... 17 from the transformer 88. To prevent reversal of potential on condenser 8 due to the inductance of the windings 4, 5, these windings are selectively short circuited when the potentials would reverse by valves 98, 99 controlled by the voltage developed on inductances 109, 110 in a potential divider across the windings, to which divider the grid circuits of control valves 102, 103 may be connected.
