Filed: 1973-09-20
Abstract: 1430282 Electric component assemblies SIEMENS AG 20 Sept 1973 [22 Sept 1972] 44179/73 Heading H1R A component assembly for use in telephone exchange systems comprises a plurality of electronic components such as inversion gate 18, signal lines for the assembly on levels 2 and 5 and A.C. supply and return lines for the assembly constituted by laminar strip conductors 3, 4 in parallel planes, the spacing of conductors 3, 4 being less than their width, the spacing 12 between capacitors 7 bridging conductors 3 and 4 and/or the shortest distance 13 between the edge of the conductors and the nearest bridging capacitor being sufficiently small that low-pass filters formed by adjacent capacitors 7 and the section of the conductor between them and/or by a capacitor 7 and the conductor section lying between it and the edge each exhibit a higher cut-off frequency than the maximum frequency of the frequency components of parasitic voltages produced in the strip conductors during operation of the assembly. The surge impedance of the strip lines is low because of their short distance apart and the bridging capacitors, accordingly the resistance of components such as 18, whatever their switching state, will be much higher than the surge impedance and, as explained in the Specification, this renders the amplitude of parasitic voltages produced on switching very low. The high cut-off frequency of the filters ensures that there is no local storage therein of parasitic voltage energy. Known remedial measures for suppressing parasitic voltages may be used in addition. For example series resistors may be inserted in the strip lines or as shown, shunt capacitors 10 whose internal resistance 9 is matched to the surge impedance of the strip lines with the bridging capacitors 7 may be connected at the terminals 6 end of the assembly. Similarly shunt capacitors 8 with internal series resistance 9 matched to the surge impedance may be connected at the opposite end. The capacitance of such capacitors, though relatively high compared with that of capacitors 7, may be much lower than in known assemblies since they are associated with the arrangement according to the invention. Preferably, the distances 12, 13 are lower than the theoretical length a parasitic voltage would run along lines 3, 4 bridged by capacitors 7 during switching of 16, assuming the assembly were long enough. Preferably the length of the strip conductors is less than this theoretical length. As shown, line 4 occupies the width of the assembly and line 3 comprises two parallel strips bridged at both ends. The distance apart of lines 3, 4 is preferably less than their distance from levels 2, 5 carrying signal circuitry. Additional levels 14, 15 may be provided. Component 18 may be a C-MOS component which, in addition to having a sufficiently high resistance, is constructed so that the D.C. supply input is substantially independent of the switching state, e.g. by using a low capacitance shunt capacitor.

Abstract: 1,001,644. Electric correspondence control systems. D. NEMAK, R. MIHALYI, and B. BAJAKI. Dec. 11, 1961 [Dec. 15,1960], No. 44271/61. Heading G1N. [Also in Division H2] In a position control system of the type in which the extent of rotation of the motor of a Ward Leonard set is regulated by a control signal, excitation windings of the Ward Leonard generator are arranged in a bridge network to receive both the control voltage and, in opposition to this, a voltage proportional to the generator output voltage, the arrangement being such that errors in the system such as those resulting from residual magnetism are compensated for. As shown, a bridge network has adjustable resistors R 1 , R 2  in one pair of opposite arms and generator excitation windings I and II in the other pair of arms. The diagonal of the bridge receiving the control signal U R  includes a further excitation winding III in series with an adjustable resistor R 3 ; the other diagonal receives, over an adjustable resistor R 4 , the generator voltage U G . Resistors R 1  and R 2  are so adjusted that the voltage U G  produces no current in winding III which is thus responsive only to the control voltage. Resistor R 4  is adjusted so that the voltage U G  produces currents in windings I and II which differ from the currents produced in those windings by the voltage U R  by an amount producing a field sufficient to eliminate the residual magnetism error of the system. In an embodiment used for positioning a ship's rudder (Fig. 2, not shown), the windings I, II and III are the exciting coils of an amplidyne supplying the generator field circuit and the initial magnitude of the control signal is dependent upon the setting of a rudder adjuster, the signal being automatically reduced to zero as the rudder takes up its selected position.
