Title: Improvements in and relating to automatic exchanges
Inventor: LEVY MAURICE MOIESE
IPC: H04Q11/04
Filed: 1950-11-23
Abstract: 759,689. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd. Nov. 23, 1951 [Nov. 23, 1950], No. 28705/50. Class 40 (4). In an automatic exchange system a calling subscriber is connected to a "calling unit" and thence to a register which, when set by dialled digits, transmits a seizing signal to the called subscriber's line circuit. The latter thereupon seizes a free speech channel and reverts to the calling unit, via the register, a signal indicative of the identity of the seized speech channel, this signal then effecting the connection of the calling unit to the seized speech channel to complete the connection. As shown in Fig. 1, the calling subscriber's line circuit 12 seizes a calling unit 15 which then seizes a free register 23 with the aid of an allotter 24. When the register is set it selects a combination of pulses from the MCDU pulse generator 26 and combines them into a single recurring pulse whose position in its time cycle indicates the number of the wanted subscriber. This pulse is passed over the common calling junction 25 to all the subscriber's line circuits and is gated into the required subscriber's line circuit 13 by a pulse having the same time position provided directly to the subscriber's line circuit by the MCDU pulse generator 26. The subscriber's line circuit 13 is seized thereby, and selects a free called unit 16 permanently associated with one of a series of multiplexed speech circuits 17, 18. Each called unit is supplied with a pair of high frequency pulses d, u from the generator 14 which are combined to produce a gating pulse for gating the speech signals to and from the appropriate channel of the multiplex systems 17, 18. Each called unit is also supplied from the low-frequency pulse generator 21 with a pair of low-frequency pulses d<1>, u<1> identifying the called unit (and hence the speech channel) and these are gated into the identification junction 25<1> and thence to the register during the period of the calling pulse. The d<1> and u<1> pulses are then gated into the register by the calling pulse and transmitted thence to the calling unit 15. The calling unit 15 is provided with a " translator " which is set by the d<1> and u<1> pulses so that it selects the corresponding d and u pulses from the highfrequency generator 14 for combination into a single pulse for gating the speech signals to and from the speech junctions 17 and 18 so completing the connection. Apart from the different pulse gating arrangements the detailed circuits are similar to those of Specification 759,682 with the exeption that in the latter Specification the " translator " is located in the called unit. Busy signalling, metering and release arrangements are similar to those of the above mentioned Specification. Specifications 759,681, 759,683, 759,684, 759,687 and 759,688 also are referred to, for alternative methods of routing the calling signals, transmission of channel identification signals and for seizing a channel in response to such signals.

Filed: 1920-10-14
Abstract: 152,359. Jager, D. Oct. 14, 1919, [Convention date]. Figured artificial stone; concretes and mortars. -Artificial marble is produced bv making several separate mixtures of different colours and consistency, superimposing the mixtures in layers, and stirring them together with or without shaking in such a manner as to avoid complete mixing. A dry mixture of 1 part Portland cement, ¢ part silver sand, and ¢ part pulverized marble is moistened with water to which is added colouring matter free from sulphuric acid to form a comparatively thick mortar. " Flame markings " are produced by mixing a similar composition of different colour with a larger proportion of water, and the composition for veins, with less water. These mixtures are superimposed, and turned over with a trowel or the like to mingle the colours. The mass is then shaken in moulds without compression, and after drying, the face layer is ground off. For reinforced concrete, the marble mass is placed in the mould, and while still moist, the moist reinforced concrete block &c. is superimposed.

Abstract: 1,140,936. Multiplex pulse code signalling. STANDARD TELEPHONES & CABLES Ltd. 23 June, 1967, No. 29101/67. Heading H4L. In a time division multiplex P.C.M. system each frame comprises n channels each having m bits one of which is used for signalling, o consecutive frames form a super frame with o Î n bits available for signalling, in each super frame some of said o x n bits are used for conveying signals which include a number of bits occurring in successive super frames and relating to the channel in which the bits occur, and a number of said o x n bits in each super frame are used as a common signal channel for signals for any of the channels. As described the system comprises 24 channels and there are 8 bits per channel of which the first bit is used for signalling or synchronizing purposes. 4 frames comprise a super frame in which in the first frame the first bits of each channel transmit signalling information which is associated with the respective channels, in the second frame the first bits are used for data transmission, in the third frame they are used as in the first frame, and in the fourth frame, the first eight of the first bits of the channels are used for order wire signalling and the remaining sixteen bits are used for synchronizing signals. Transmitting equipment.-Incoming speech signals are sampled by gates G1 &c. Fig. 1, and supplied via a common coder 1 and sync. and signal insertion device 6 to the line. Signalling on the incoming line which is associated with the channel is detected at 2 to produce an output OP1 which is supplied to device 6. Order wire signals (which are not associated in time with the corresponding channel) when received at 2 produce an output OP2 and also set a bi-stable T1 which allows the signal to be gated to a signal detector 3 which passes the signal to a store 5 via a coder 4 if a bi-stable T2 is in the reset condition indicating that the store is free. Address codes for the various lines are supplied in sequence to an address store 7 and when the detector 3 detects a potential OP2 it opens the address input gate so that the corresponding address is stored at 7. This also sets the bi-stable T2 via delay D to indicate that the store is busy, and resets T1. The signals from 5 and 7 are inserted in known manner at 6 and may require a number of super frames to complete the transmission. The sync. signals also are inserted in known manner. Bi-stable T2 is reset after the stored signal has beendealt with. Receiving equipment, Fig. 2 (not shown).- This operates in a converse manner to the transmitter and includes an order wire reception store comprising a signal store and an address store associated with signal and address decoders, the address signal gating the order wire signal on to the appropriate output line. An extraction circuit separates the various order wire and other signals and the speech signals in accordance with their time of arrival.

Title: Improvements in electric circuit arrangements for producing sharp edged impulses
IPC: H03K5/01
Filed: 1956-09-26
Abstract: 828,166. Converting; changing wave-shapes. GENERAL ELECTRIC CO. Sept. 26, 1956 [Sept. 26, 1955], No. 29397/56. Class 38 (2). An alternating voltage having one half cycle A of constant amplitude and the other half-wave B part sinusoidal, is developed at the input to choke 15 by adding direct voltage 14 to sinusoidal alternating voltage 11 and shortcircuiting the alternating voltage 14 by rectifier 13 and resistor 12, the voltage drop across resistor 12 being equal to voltage 14. The alternating voltage A, B is applied to pulse transformer 18 which develops a sharp-edged pulse from the leading edge of half-wave A, through a rectifier 16 which blocks half-wave B, and saturable reactor 15 which acts as a switch to control the instant variable over 180 degrees at which half-wave A is applied to transformer 18 bv variation of current in winding 19, and thereby vary its phase. The pulses may be supplied to the grids of gas-filled electron tubes used as rectifiers. So that reactor 15 returns to the same state at the end of each cycle areas A and B are made equal by appropriate choice of relative values of the voltages 11 and 14. Two pulse transformers may be supplied from two similar circuits through separate saturable reactors having their biasing windings 19 in series and so sensed that two trains of pulses 180 degrees apart are shifted similarly, or alternatively that one or other pulse train only is produced in accordance with the polarity of the D.C. applied to windings 19 (Fig. 3, not shown). The derivation of pulses from two phase and three-phase sources by similar circuits is also described (Fig. 5, not shown). D.C. component 14 may be derived by rectification of the A.C. source. A circuit in which the rectifier is connected between the input transformer and the battery, and the asymmetric alternating voltage is taken from between the transformer and resistor has a higher impedance viewed from the load (Fig. 6, not shown). In a further modification a voltage 74 having the wave shape shown in Fig. 8 is derived from the circuit of Fig. 7. This voltage is the algebraic sum of the rectified ripple voltage across inductor 65, which is connected in series with paralleled capacitor 66 and resistor 67 across four bridge-connected rectifiers 61, 62, 63, 64, and a voltage derived from transformer 68. Two such circuits may be associated to produce output pulses from both halves of the supply voltage waves (Fig. 9, not shown). To increase the length of the constant voltage portion A and thereby of the interval over which the phase of the output pulse may be shifted, the circuit of Fig. 1 may be modified by connecting the rectifier to a point on a potentiometer resistor across the battery (Fig. 10, not shown).
