Filed: 1928-11-20
Abstract: 329,658. Siemens - Schuckertwerke Akt.-Ges. Aug. 27, 1928, [Covention date]. Divided on 318,095. Systems depending on two or more machines ; transmission, conductor arrangements.-The efficiency of high-potential long-distance lines is increased by compensating the self-inductance of the line by wattless-current, producers in series in the line and compensating independently the selfcapacity of the line by wattless-current producers in parallel to the line. The wattless-current producers are distributed along the line at intervals small compared with the natural wavelength of the currents in the line i.e. the wavelength corrresponding to the constants of the uncompensated line, and may be static condensers c and choking- coils ! l or may comprise synchronous machines, asynchronous phase-shifters &c. They are given fixed values determined by formulµ given in the Specification. The line presents ohmic resistance only, the transmission distance being limited only by this resistance and by heating of the line Bare conductors of large inductance and small self-capacity or cables of small inductance and large self-capacity may be used, the latter being better suited for large outputs and requiring smaller compensating condensers. 3-phase systems may be compensated. Specification 318,095 is referred to.

Title: Improvements in or relating to translating circuits
Inventor: THREADGOLD RONALD
IPC: H04Q3/42
Filed: 1954-03-27
Abstract: 757,049. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Feb. 2, 1955 [March 27, 1954], No. 9003/54. Class 40 (4). In a translator a set of cold cathode tubes, equal in number to the maximum number of routing digits required, is provided for each possible dialled exchange code, all the tubes of a particular set being struck in response to the relevant exchange code and the striking of each said tube causing the striking of at least one of the tubes in one of a number of groups of tubes representative of all possible values of the translated (routing) digits by the application of a negative pulse to its cathode. The invention is described as applied to the translation of three-digit exchange codes into routing digits to a maximum of six. The three exchange code digits select one of a thousand sets of tubes, each containing six cold cathode tubes such as VK1, by applying a positive bias to the trigger electrodes of a column of sets of tubes over a lead such as 10, and a negative pulse to the cathodes of a row of sets of tubes over a lead such as 11 so that only a single set of tubes receives both bias and pulse and all the tubes of that set are fired. Each tube VK2 represents a particular value of one routing digit, there being six groups each of ten tubes VK2. Tubes VK1 (of different sets) which are associated with the same value of a particular routing digit share the same anode resistor R1 and are connected via capacitor C1 to the cathode of the same VK2 tube, so that if any of these tubes VK1 fires a negative pulse is applied to the cathode of the VK2 tube which strikes. The marking derived from a tube VK2 depends upon the code used to indicate the routing digits. If this is decimal each tube VK2 is connected to a particular one of ten output tubes VK3; if binary to one or more of, say, four output tubes VK3. When a tube VK2 conducts it fires the associated tube(s) VK3, the rise in cathode potential marking lead(s) 12. In a modification (Fig. 2, not shown) the isolating tubes (VK2) are omitted, output tubes are fired by a negative pulse on the cathode, and leads from their anode resistors are marked in accordance with the translated digits.
