Title: Improvements in or relating to time division multiplex switching systems
IPC: H04Q11/04
Filed: 1961-06-09
Abstract: 981,338. Automatic exchange systems. SIEMENS & HALSKE A.G. June 9, 1961 [June 10, 1960], No. 20935/61. Heading H4K. In a time division multiplex system having two circulating stores one for calling subscribers' addresses and one for the called subscribers' addresses, pulses therefrom opening the subscribers' multiplex gates in synchronism, a gate is included between the called subscriber's store and his multiplex gate, which gate is only operated after a test is carried out to ensure that the called subscriber is free. As shown connections between calling and called subscribers are established by inserting pulses of the same phase into combinations of delay line stores Ua, representing the calling line, and Ub, representing the called line. The delay lines feed respective decoders Da, Db having an output per line, which open gates such as S1, Sx at the phase in question to establish a pulse multiplex connection between subscribers over lead SM. Connection between the delay lines Ub and the decoder Db cannot however be established unless gates such as Sp1 are pulsed from delay line Ud there being such a gate for the output of each delay line in Ub. Digits representing the wanted subscriber are received from the calling subscriber in the form of voice-frequency combinations in a receiver such as Z1 and each digit as it is received is suitably recoded and inserted in the calling subscriber's phase in the appropriate combination of delay lines of Ub, the store Ub having a combination of delay lines for each digital phase. A scanning device consisting of a cyclically stepping register G sets up each subscriber's identity in turn, each for the duration of a multiplex cycle. Comparators Va, Vb compare the identities of subscribers stored in Ua, Ub at any pulse phase with the identity present in G to give an indication to control circuit E. Thus if E receives an indication from Va, or an indication from Vb at the same phase as a pulse received from Ud it knows that the subscriber is busy. If also at some other phase it receives an indication from Vb but no pulse from Ud it is aware of a request for a connection to be set up. If the line has tested free the control circuit thereupon inserts a pulse in the correct phase in Ud and the output therefrom completes the connection by operating gate Sp1 In a modification the output from Ud enables a gate to pass an accurately timed clock pulse which is applied to enable the decoder as a whole. Specifications 981,335, 981,336, 981,337 and 981,339 are referred to.

Patent GB-212489-A (GB)
Abstract: 212,489. Wood, A. F., Stott, W., and Telephone Manufacturing Co., Ltd. April 14, 1923. Automatic exchange systems; selectors.-A system in which each subscriber has his own connector at the exchange has the following features. (a) Each subscriber has a single speech terminal and a test terminal in the banks and both these are made dead when his connector is off-normal. (b) The test terminals of an idle subscriber are connected to battery over a back contact of his line relay. (c) The line relay is connected over an off-normal contact to the speech terminals and is operated when one of these is seized, to supply ringing current. (d) The test relay is slow acting and is initially energized over one of its own back contacts. (c) The line relay and stepping means are mechanically related so that the line relay when de-energized holds the stepping and holding pawls clear of their respective ratchets and so acts as the release magnet. Selection of wanted subscriber. The substation has three wires going to the exchange. The calling party sets his impulse transmitter to the wanted number and then removes his handset to release it. Line relay 1 energizes, disconnects negative battery from the test terminals and connects positive battery to the stepping magnet 9. The impulse transmitter closes the springs 38 a number of times to bridge the b and c substation wires and the wiper carriage is stepped to the wanted terminals. Off normal springs 23, 24, render the terminals D, E, dead. Busy test. If the wanted line is busy its test terminal is dead and nothing further happens. Supply of ringing current. If the wanted line is idle its test terminal is connected to negative battery and slow-acting relay 14 energizes over interrupter springs 12, 13 which prevented its operation during the stepping impulses. Relay 14 locks up under control of the line relay and connects wiper D<1> to negative battery over the calling a, b loop, thereby energizing the wanted line relay. This relay marks the called party busy by disconnecting his test terminal and at contact 4 completes a circuit over the band c wires for the direct current bell 37 in series with magnet 9, which is not operated owing to the rapid interruptions of the bell. Talking circuit. When the called party removes his handset the circuit shown in Fig. 2, is completed, the line relays 1 serving as feed impedances. Release. When the calling line relay falls back the members 49, 50, Fig. 3, lift the stepping and holding pawls 44, 46 clear of their ratchets and the wiper carriage falls to normal. Operation if a subscriber when called has his number sender off normal. When the called subscriber removes his handset he releases his number dial and operates his connector which at springs 23, 26 disconnects his talking terminals and prevents the original calling party from maintaining the connection. Specification 206,890 is referred to.

Title: Improvements in or relating to Electric Switches.
IPC: H01H9/22
Filed: 1918-12-19
Abstract: 136,650. Joyce, V. E., and Park Royal Engineering Works, Ltd. Dec. 19, 918. Switches, quick-break; switch mechanism interlocking with lids. -Switch mechanism of the. quickbreak type, mounted on an operating-plunger passing through the hinged lid of the box, is combined with means for locking the lid so that it is impossible to open the lid until the switch is in the fully off position, and it is impossible to close this switch until the lid has been closed and looked. The locking-means, which are under the control of the switch mechanism, are operated separately by hand. In the con. struction shown, the movable contact-carrying member is carried by a plunger 9 sliding in an air-tight manner through the lid of the casing and normally held in the off position by springs 18 surrounding guide-plungers 15. The switch is retained in the closed position by spring-pressed steel balls 19 engaging recesses in the plunger. The operating handle is pivoted on the lid and engages with a slot in the plunger, which allows of lost-motion. The plunger passes through a keyhole slot 31 in a sliding locking-plate 23, which is mounted on the lid and has a catch at its other end for engagement with a projection 28 of the box; or, as shown, the locking-plate is linked to a hooked catch 25<a> pivoted on the lid. In the closed positions shown, the plunger completely fills the circular part of the keyhole slot, and consequently the locking-plate cannot be moved to release the catch 25<a>. When, however, the switch is brought to the off position, slots 32 formed in the plunger come into line with the locking-plate, thereby allowing the plate to be moved separately, by hand, so that the rectangular part of the keyhole slot engages the plunger at its slotted part. The lid can then be opened, carrying with it the switching-mechanism. With the lid open, the switch handle may be operated to move the contact member towards the fixed contacts; but this involves sliding back the locking-plate towards the plunger, and, in this position of the locking-plate, the catch 25<a> engages with the edge of the box if an attempt is made to close the lid. If the switch mechanism is restored to the open position, the locking plate can be moved so that the catch clears the box. According to one of the Provisional Specifications, the locking-plate may be held in its two positions bv a projection on the switch handle, and, instead of a plate, a bolt may be used which, in the closed position, slides into a hole in an extension of the box projecting through a hole in the cover.
