Title: Transit exchange for asynchronous data
IPC: H04L25/04
Filed: 1974-07-29
Abstract: 1480906 Data exchanges TELEFONAKTIEBOLAGET L M ERICSSON 29 July 1974 [10 Aug 1973] 33464/74 Heading H4P In a transit exchange for transmission of asynchronous data signals with a given character structure and data rate from sending terminal equipments to receiving terminal equipments the exchange comprises switching equipment SU, Fig. 1, and sampling equipment SA, common to sending terminal equipments T101- T416 and working in a time division multiplex manner to sample over incoming lines the momentary values of received data pulses by means of sampling pulses. The switching equipment includes a detector AA, Figs. 1 and 3, which works synchronously with the sampling device SA and consists of decoder logic AKL which works in time division manner and a decoder memory AKM arranged so that by successive processing of sampling pulses it establishes the binary information content in each data pulse and in correspondence with the established value produces a binary indication signal. The switching equipment further includes an intermediate memory FM which stores the values of the indication signal in an address belonging to the respective receiving terminal equipment, regeneration devices RA 101-RA 416 each associated with a respective receiving terminal equipment and a read out  equipment UA which cyclically transfers the values of the indication signals from the intermediate memory FM to the regeneration devices to form from the received indication values data pulses which alter their value in step with the indication signals. For character elements arriving from A or B subscribers information is stored in addresses 101 and 416 of the decoder memory AKM. On write-in in the buffer memory BM of the intermediate memory FM which comprises a parallelseries converter the element information derived from the A subscriber is placed in the B subscriber's memory cell and vice-versa. For this purpose address information is used which has been stored in the address register memory ARM during a switching phase during which selection information has been received from the A subscriber and analysed by the control processor SU. The control processor SU has a switch memory KM in which received character elements are temporarily stored while being processed  by a logic equipment KL. The capacity of the transit exchange can be extended by employing three sampling devices (SA1-SA3, Fig. 5, not shown) three detector (AA1-AA3) and three corresponding readout devices (UA1- UA3) successively operated in cyclic pattern. Alternatively the capacity can be extended by increasing the capacity of the buffer memory BM and output buffer UB in a number of identical units of the type described in Figs. 1 and 3 and interconnecting these units with one another with OR circuits (G1-G3, Fig. 6, not shown). Specification 1,480,907 is referred to.

Title: Improvements in or relating to electromagnetically operated switching arrangements
IPC: H02M1/28
Filed: 1953-12-04
Abstract: 744,225. Converting. SIEMENS-SCHUCKERTWERKE AKT.-GES. Dec. 4, 1953 [Dec. 5, 1952], No. 33837/53. Class 38 (2). [Also in Group XXXVII] An electromagnetically-operated switch, used for example in a contact converter system, is closed by the movement of a contact in several stages. In a system in which a D.C. load 9 is energized from a polyphase A.C. supply 12 through contact converters of which one is .shown having a movable contact 3, this contact, which may also form an armature, is moved by energization of windings 6, 7 a part of the distance towards closure, and by energization of windings 4, 5 the remaining part. As this final distance is small, high energization with consequent great force acting on the contact does not result in sufficient kinetic energy to produce bounce, but gives good contact pressure. Winding 6 is energized from two phases of the supply through a phase chamber 15 which determines the time of initiation of contact movement and through saturable chokes 13, 14 of unequal ratios to produce current of trapezoidal waveforms with unequal lengths of the positive and negative halves, the negative half being opposed by the M.M.F. produced by winding 7 which carries the D.C. saturating current of chokes 13, 14. The intermediate position reached by the contact 3 is determined by the opening spring. The final closing operation is initiated by the firing of valve 18 which results in energization of windings 4, 5.
