Title: Improvements in or relating to telephone systems
IPC: H04M11/04
Filed: 1945-10-05
Abstract: 601,849. Fire alarm systems. STANDARD TELEPHONES & CABLES, Ltd., and BATES, E. F. Oct. 5, 1945, No. 25986. [Class 40 (iv)] [Also in Group XXXVIII] In a call-box for a single-wire closed circuit telephone system, e.g. an ambulance call or a police call system, a choice of circuit conditions is made automatically, on the initiation of a call, to suit the existing line condition. As shown, Fig. 1, a mounting plate 1 carries two yokes 2, 3 with armatures 5, 6, the latter yoke being fitted with a relay coil LR, while the armature 5 acts merely as a lever. While the door of the box is closed the lever 17 is held rotated anti-clockwise, the spring contacts ds being closed directly thereby, while the plate 15 is moved by the spring 21 to operate the lever 5 and the armature 6 controlling the contacts rr1,2 and lr1,2,3 respectively, the handset being on its cradle, and all contacts being as shown in Fig. 2. After opening of the door operation depends upon the line condition. No fault on line. When the door is opened, LR operates momentarily in the line loop between the opening of ds and the closure of rr1, and is held operated by the latching lever 9. The removal of the handset momentarily opens the line to signal the central station before connecting the microphone T and receiver R in the line loop via lr1. Earth fault on either side of box. Relay LR pulls up momentarily in a circuit between the earth fault and the central station and operation is as above. Open circuit on either side of box or shortcircuit'in the box. Relay LR does not operate and arm 11 prevents latching of armature 6. Earth is connected over rr2, lr3 and gs2 to either LA or LB and thence to the central station. Removal of the handset signals the control station and inserts the telephone set in the earthed circuit.

Abstract: 934,341. Electric selective signalling. CREED & CO. Ltd. July 6, 1962, No. 26059/62. Class 40 (1). [Also in Group XIX] The number of pulses entered into a conventional binary counter BC is read out in Gray code from a set of bi-stable devices F5-F10 by arranging that each bi-stable device is reversed when the associated stage of the counter changes to 1. Inputs to the counter and the bi-stable devices are through gates G1- G7 which are opened with a potential is applied to lead SW.ON. Each bi-stable device has two outputs so that the complement can also be indicated. The counter and the bi-stable devices can be reset to zero. Alternatively, the bi-stable devices can be reset to a different number if a diffrent code is used. The number in a store can be read out by connecting the store to the counter through a comparator which enables the counter until parity is established. Similarly, a store in Gray code can be coupled to the bi-stable devices so as to obtain conversion and read-out from the conventional binary counter.

Filed: 1950-10-31
Abstract: 681,234. Hydraulic brakes. TEVES, A., TEVES, H., and TEVES, E. A., (trading as TEVES MASCHINEN-UND ARMATURENFABRIK KOM.-GES, A.). Oct. 31, 1950 [Oct. 31, 1949], No. 26562/50. Class 103 (i). In a control valve device for vehicle hydraulic brakes, of the type in which the pressure is produced by a variable delivery pump having a plunger 7 reciprocated by an eccentric 2, 3, the delivery being adjusted, as shown, by rotating the plunger 7 so as to alter the position of a groove 11 therein relative to the liquid inlet ports 9, the control rod 16 by which, through the engagement of a toothed section 17 with a pinion 18 the plunger 7 is rotated, is subject, on the one hand to the pressure in the braking cylinder connected to pipe 14 and acting on piston 20, and on the other hand, to the force on an actuator member 26, through the medium of a resilient member such as the spring 25. Movement of ram 26 to apply the brakes causes a compression of the spring 25, resulting in rotation of the plunger 7 so that liquid is displaced through the non-return valve 12. The braking pressure reacts back on the piston 20 and causes the control rod 16, 17 to be displaced against spring 25 until the spring force and braking pressure are in equilibrium. Any variation of force on the ram 26 now results in a corresponding adjustment through the springs 25 of the plunger 7. In a modified arrangement shown in Fig. 3, the control pedal 31 operates the pump control rod 36 through the medium of a single stroke-type hydraulic master cylinder. The hydraulic system connected at port 33 forms the resilient member corresponding to the spring 25 and at the same time permits direct application of the brakes in the event of failure of the pump.
