Abstract: 684,471. Valve relay circuits. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 31, 1947. [Oct. 24, 1946], No. 34970/47. Class 40 (vi). [Also in Group XL (b)] In a circuit arrangement for receiving signal pulses comprising at least two valves constituting a trigger circuit and having at least two conditions of stability from either of which it can be triggered by the application of a triggering pulse to one of the valves, an energystoring device is connected between the anodes of the two valves or of two of the valves, and the parameters of the circuit are such that triggering action cannot be completed unless the triggering pulse has persisted for at least one half of the period of a signal element. In the circuit shown in Fig. 1, utilized in an " on-off " signalling system in which received marks and spaces result in the application of a negative voltage via condensers C2, C1 to the terminals b, a respectively, the valves B1, B2 are respectively non-conducting and conducting if a space element has been duly received, and the capacitor C3 has its right-hand plate at a negative potential. If a mark element is now received, the negative potential applied to the terminal b renders the valve B2 non-conducting and current flows over resistor R2 to the righthand plate of the capacitor C3 with a gradually increasing current flow to the grid of the valve B1 which is made conducting after a time dependent mainly on the values of C3, R2. Current flows in the anode circuit of the valve B1 and increases gradually until the capacitor C3 is fully charged in the reverse direction. A further arrangement, Fig. 2 (not shown), for a frequency-shift signalling system comprises three valves reciprocally coupled in pairs and having their respective grids supplied with a positive pulse in response to marking and spacing frequencies and to the no-signal or normal condition. Specification 655,542, [Group XL (b)], is referred to.

Title: Improvements in devices for making and breaking electric circuits
IPC: H01H3/26
Filed: 1922-12-27
Abstract: 212,011. Zweigbergk, T. Dec. 27, 1922. Switches, partly electromagnetic. -A circuitbreaker which may be used in the motor control described in Specification 175,877 [Class 38 (iii), Electric motor control systems &c.] is arranged so that to close the circuit joint mechanical and electromagnetic devices are required, either of which may effect the opening of the circuit. The mechanical device comprises a cam 1 on the motor-driven contactor shaft 41 having a recess 2 co-operating with a roller at the end of a pivoted lever 4. A pair of toggle links 12, 13 extend between the lever 4 and a pivoted lever 16 carrying a contact 17 adapted to co-operate with a fixed contact 18, a spring 19 tending to hold the contacts apart. A link 10 is attached between the common pivot 11 of links 12, 13 and an arm of a bell-crank lever 8, the other arm carrying an armature 7 co-operating with an electro-magnet. 6. When the circuit of the solenoid 6 is closed on moving the master controller from its " off " position the solenoid 6 is energised attracting the armature 7 and bringing the links 12, 13 almost to their dead-centre position. The contact lever 16 is rotated through a small arc, the contact 17 being still some distance from the fixed contact 18 and the spring 19 being only slightly compressed. When the shaft 41 is subsequently rotated the straightened links 12, 13 act as a strut between levers 4 and 16 so that as the roller rides out of the recess 2 the contact 17 is driven home against the fixed contact 18 against the full force of the spring 19. If the master controller is now brought again to the off position the deenergization of the coil 6 and consequent release of the armature 7 allow the links 12, 13 to collapse quickly causing a quick break at contacts 17, 18. A small switch 2 is interlocked with an arm 28 integral with the contact lever 16. The spring-retracted contact lever is pivoted at 23 and operated, when the armature 7 is attracted through a push rod 21. A depending arm 27 of the movable contact member co-operates with a projection 30 on the arm 28 to ensure that this switch is released only after the main circuitbreaker has been opened.

Filed: 1938-12-09
Abstract: 522,577. Mixing valves. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Dec. 9, 1938, No. 35977. [Class 135] A mixing valve device has hot and cold water control valves disposed on opposite sides of the fulcrum of a rocking lever actuated by a thermostatic bellows adjacent the outlet. In the form shown in Fig. 1, the hot and cold supplies are controlled by valves 10, 11 interconnected by a lever 18 held against an adjustable pivot 16 by a spring 21. The pivot 16 is carried by a slidable carriage 15 adjusted by a screwed spindle 13 provided with a stuffing-box 14 and handle 12. An extension 22 of the lever 18 engages the free end of a thermal bellow 23 arranged near the outlet port 9. The bellows is loaded by a spring 25 arranged between an abutment 24 carried by the bellows and an abutment 26 adjustably mounted on a screwed spindle 27 rotatably mounted in the casing, rotation of the abutment being prevented by projections engaging grooves 28 in the casing. Leakage is prevented by a collar 31 on the spindle bearing against a packing 32 under the action of a spring 33 arranged within a knob 30. The knob is internally screwthreaded to co-operate with a slidable indicator 34. In a modification, the two valves are actuated by a three-armed lever turning on fixed pivots. The cold water valve may be fitted with a bellows balancing device. Fig. 5 shows a device adapted to be fitted to the outlet from the mixing valve to direct the outflow either to a shower or to a bath. It comprises a lift valve member normally held to its seat by a spring 41 but removed therefrom when the valve is rotated to cause cam 42 to rise out of a fixed mating recess 43. According to the Provisional Specification the screw 13 can be replaced by a cam.
