Title: Improvements in or relating to multiplying devices
IPC: G06G7/164
Filed: 1960-04-22
Abstract: 886,265. Electric analogue calculating systems; power measurements; measuring bridges. LANDIS & GYR A.G. April 22, 1960 [April 25, 1959], No. 14237/60. Class 37. A multiplication device comprises a bridge circuit 5, Fig. 1, fed with direct current, e.g. from a battery 6, having arms comprising identical resistors 3, 4 and identical resistance members 1, 2 whose resistance is much less than that of resistors 3, 4 and which varies with an applied magnetic field, and two series-connected energizing windings 8, 9, the signals U 1 , U 2  representing the two multiplicands being applied across terminals 15, 16 and between terminal 19 and tapping 14 on potentiometer 13, respectively. The resistance of members 1, 2 varies in quadratic relationship with the magnetic field applied by windings 8, 9, and the output voltage of the bridge appearing across terminals 39, 40 is proportional to the product U 1 , U 2 . The device of Fig. 1 may be employed to measure the apparent power in an A.C. mains if U 1  is a direct voltage, proportional to the current flowing in the mains, and U 2  is a direct voltage, proportional to the mains voltage. Fig. 3 shows a device for measuring the active power in a single phase A.C. mains. An alternating voltage proportional to the current flowing through load 27 is applied across terminals 15, 16 by means of a transformer 25, and an alternating voltage proportional to the mains voltage is applied between terminal 19 and the centre tapping 28 of secondary winding 24 of transformer 25. The D.C. supply for the bridge is obtained from the mains by means of a rectifier 33 and smoothing circuit 34, 35, one or more Zener diodes 36 being provided for voltage stabilization. The wattless power in the mains may be measured by introducing an additional phase-displacement of 90 degrees in one of the voltages applied across terminals 19, 20 or 15, 16. Power in a polyphase mains supply may be measured using a plurality of such multiplication devices, the bridge outputs of which are connected in series with an instrument indicating the sum of the outputs. Initial inequalities between members 1, 2 may be compensated by replacing resistors 3, 4 by a potentiometer and including a potentiometer between members 1, 2, the direct current being supplied to the bridge through tappings on the potentiometers. The fields produced by equal voltages across windings 8, 9 may be made equal by connecting an adjustable inductance in parallel with one or both of windings 8, 9.

Abstract: 1,170,735. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd., STANDARD TELEPHONES & CABLES Ltd., and H.M. POSTMASTER GENERAL. 29 March, 1967 [31 March, 1966], No. 14378/66. Heading H4K. In an exchange of the kind described in Specification 1,057,218 in which subscribers' lines and incoming junctions as well as register terminations are scanned continuously for calling conditions and connections are set up under the control of a main control unit in association with a register, arrangements are made to avoid possible mutilation of the first digit received from a step-by-step exchange. After detection of a calling condition, the detection by the control unit during later scans of an incoming impulse before a path has been completed to the register causes the programe to be changed to direct that impulse to a store associated with the register which takes subsequent impulses received directly by the register. If, however, more than one impulse is detected before the path to the register is completed, a busy condition is set up.

Filed: 1968-03-27
Abstract: 1,215,495. Automatic registration control. HURLETRON Inc. March 27, 1968 [May 9, 1967], No.14725/68. Heading G3R. Longitudinal registration error between a plurality of consecutive patterns on a moving web and means for performing consecutive operations on the web is automatically corrected by signals dependent on registration error, web speed, and rate of correction. In Fig. 1, a web 10, previously printed with successive patterns e.g. in a rotogravure press, is fed to a second printing cylinder 38. A computer 16 compares the phase of suitably shaped ramp voltages produced by a signal generator 48 driven by cylinder 38 with pulses from a photoelectric device 44 scanning registration marks on the web. Any variation, representing lack of register, produces a signal which is, in effect, multiplied by a signal derived from a tacho generator 14 in dependence on the speed of the web to produce a signal which determines the rate of correction by a D.C. servomotor 18. This is achieved by a non-linear transistorized follow-up motor circuit which balances the registration error signal against the product of a rate of correction signal from a tacho generator (not shown) driven by servomotor 18, and the reciprocal of the web speed signal. Servomotor 18, the armature current of which is controlled through a magnetic amplifier and SCRs or thyratrons periodically corrects registration by adjusting a pulley 28 and thus varying the length of travel of the web. A meter may be associated with computer 16 to indicate the registration error, and a visual or audio device may be arranged to indicate the amount of correction. The system is made insensitive to slow, long-term changes and is provided with fail-safe and manual/automatic changeover relays. A signal dependent on rate of change of error may be introduced into the control system. In modifications involving resistor-condenser networks, correction is applied for periods corresponding to the magnitude of registration error at rates proportional to the speed of the web, or vice versa.
