Title: Improvements in or relating to pcm time-division multiplex exchange systems
IPC: H04Q11/04
Filed: 1970-03-03
Abstract: 1,263,006. Automatic exchange systems. SIEMENS A.G. 3 March, 1970 [4 March, 1969], No. 10002/70. Heading H4K. In a PCM, TDM exchange utilizing one time slot for transmitting signalling data in respect of connections taking place in the other time slots and wherein each data signal is accompanied by a designation signal for identifying the time slot to which the data signal relates, the designation signal on an incoming highway is decoded so as to allow the data to be switched through at the time slot to which it relates whereafter a new designation signal is added to the data in respect of the new time slot which is allocated to the call on an outgoing highway. If the exchange is a terminal exchange the data may be processed therein by the local control circuitry. In addition, data in respect of an outgoing call may be inserted by the local control circuitry into the data time slot of the relevent outgoing highway. As shown, data and designation signals occurring during a data time slot on an incoming highway PCMe are fed into a shift register SRe. The cyclical output of an address generator ZGe is compared with the stored designation signals so as to read out the related data signals during the relevant time slots. The data passes through a data switching network SKF in synchronism with the corresponding intelligence signal passing through speech switching network KF. The networks may incorporate delay lines for purposes of time slot transposition. At the output side of the network the data is gated into a relevant compartment of a shift register SRs under the control of another cyclically operable address generator ZGs which also inserts the corresponding designation signal into the register. During the data time slot in the outgoing highway PCMs the data in the register is read-out in serial fashion for onward transmission. Additional receiving register SReK and transmitting register SRys are provided for conveying data to and from the local control circuits K, Y when the exchange is acting as a terminal exchange.

Abstract: 825,818. Railway classification yard brake systems. GENERAL RAILWAY SIGNAL CO. March 28, 1958 [March 29, 1957], No. 10115/58. Class 103 (1). In a control system for a gravity-operated railway classification yard, including a group retarder in a stretch of track feeding a group of classification tracks, means are provided for detecting a car passing along the stretch of track and for releasing the retarder when a car within it has had its speed reduced to a selected speed, a car counter being provided for each of the classification tracks, and for controlling, in accordance with the fullness of a classification track, as determined by its counter, the retarder release speed for a car destined for that track, and means controlled, in accordance with whichever classification track has been pretermined as the destination of a detected car for actuating the car counter for that track in response to the detection of that car. As shown in Figs. 1A, 1B and 2, the control system comprises a hump retarder (not shown) and a group retarder, which are normally closed in their braking positions, and each is automatically opened when a car within the retarder has reduced its speed to a predetermined rate. The degree of retardation applied is subject to a control exercized by a weight detector WD, the cars being released from the hump retarder at substantially the same speed, while the release speed for each car in each of the group car retarders is computed in accordance with the rollability of the car and other factors. As a car passes over the detector WD, the relay 21 is actuated by the pulsing of contact 21 by the respective axles of each of the cars, and the weight registrations are passed on to the control circuit generally by the operation of relays BLP, V1, V2 and V3 and transfer relay TN to relays B1 and B2. The control panel is provided with wheel indications of track fullness by means of lamps TK, one being provided for each car (or a pair of two axle cars), that occupy the track. A lamp EK is also provided to indicate the condition when a classification track is entirely unoccupied. The group retarder is subject to the control action of a modifier unit which governs in accordance with track fullness by the shunting of resistors 1R, 2R, 4R and 8R by the back contacts 64, 65, 66 and 67 of relays DA, DB, DC and DD respectively. If, for example, there is only one car counted into the car counter 3VS, the relay DA is picked up when classification track 3 is selected by the storage relays upon energization of a circuit extending from (+), including front contact 78 of TBP, front contact 48 of relay TN, back contact 45 of relay B1, back contact 46 of relay B2, contact 47 of stepping switch 3V5, wire 48, rectifier 49, wire 50 and winding of relay DA to (-).
