Filed: 1971-04-19
Abstract: 1351854 Automatic control of registration "SOVERDIA" GES FUR GEMEINWOHL mbH 19 April 1971 [1 April 1970] 25871/71 Heading G3R [Also in Division B6] The registration with which a plate cylinder prints on a web 1 is monitored, and correction of registration errors made possible, by comparing pulses 4 produced by a photoelectric head 3 each timespaced preprinted marks 2 on the web 1 pass the head 3 with two spaced photoelectrically produced pulses produced al each revolution of the plate cylinder. When registration is perfect the pulses 4 from the head 3 are timed between, and in part overlap, the spaced pulses, the periods of overlap at each end of the pulses 4 from the head 3 being equal. An error in registration causes the pulses 4 each to overlap either the preceding or the following of the spaced pulses by more than the other. AND gates 17 separate the periods of overlap into derivative pulses 18, 19 and these are integrated to produce voltages whose difference is displayed by an instrument 32 and used to control a servomotor 44 which acts on registration-setting means associated with the plate cylinder to restore register.

Abstract: 1286434 Electric motors AMPEX CORP 19 April 1971 [2 April 1970] 25869/71 Heading H2A In a machine employing a permanent magnet rotor 134, the current through the stator coils 141 ... 148 is controlled by Hall plates 151, 152 and also by clock pulses generated by ferromagnetic strips 159 passing a magnetic pick-up 161. The sine waves from generator 151, 152 are passed to a decoder 166, Fig. 3 (not shown), where, after amplification and inversion and combination, where necessary, eight sets of rectangular waveforms equally shifted in phase are produced, Fig. 5 (not shown). These are fed to a counter 201, Fig. 4 (not shown), precise timing being effected by the clock pulses derived from shaper 202. The resulting square waves are fed to a series of gates in a circuit 221 to produce precise rectangular pulses lasting 90 degrees of the rotation, so that adjacent pulses overlap by half a pulse width. These pulses control switches 232 connected to the windings, the centre point 242 of which is fed from a motor drive amplifier 244. The circuit is employed in a video tape recorder.
Patent GB-532633-A (GB)
Title: Improvements in or relating to electronic signal distributors
IPC: H04L5/24
Filed: 1939-09-15
Abstract: 532,633. Thermionic distributers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept 15, 1939, No. 25935. Convention date, Sept. 16, 1938. [Classes 40 (iii)] and 40 (v)] A distributer, Fig. 3, for start-stop signalling systems, comprises a series of valves ST1 ... ST5 each rendered conducting upon cessation of current through the preceding valve, and a starting valve ST normally conducting at its anode 39. The action is started by making grid 19 negative, thereby blocking anode 39. Decay of current in primary of transformer T1 forces grid 20 positive so that anode 40 conducts and continues to conduct until condenser K has discharged. Whereupon decay of current through transformer T2 causes valve ST1 to conduct for a short period, and the sequence proceeds to valve ST5, and is only restarted after anode 39 has again conducted and been again blocked. The transmitter, Fig. 3, normally applies potential to the line circuit 38 due to current from anode 39 flowing through resistance 37. Closure of one or more contacts C1 ... C5 causes corresponding relays R1 ... R5 to lock-up, as well as a relay CR. Current through coil CR biases grid 19 negative and so removes the normal potential from the line 38, and starts the distributer. Each valve ST1 ... ST5, when conductive allows current to flow through its left-hand anode and resistance 37 only if corresponding relay R1 ... R5 is actuated. Pulses are thus sent to line 38 corresponding to actuation of contacts C1 ... C5. Anode 50 of valve ST5 when conducting operates relay SR to open holding circuits of relays CR and R1 ... R5 and thus restore distributer to its initial state. The line 38 may be connected directly to the receiver or preferably through a tone-generator thereto. The receiver, Fig. 4, comprises a rectifier 95 for the tone signal, and a valve 97 maintained conducting as long as the tone is received. Cessation of tone causes decay of current in the primary of transformer TT1, whereupon valve RT is rendered conductive. Current through anode 105 causes relay R10 to lockup and prevent signal pulses being applied to transformer TT1, and current through anode 106 causes sequential operation of distributer valves RT1 ... RT5, in a similar manner to valves ST1 ... ST5. Signal pulses received whilst any valve RT1 ... RT5 is conductive pass through the left-hand anode and cause corresponding relay R11 ... R15 to lock-up. Anode 108 of valve RT5 when conducting operates relay R16 to open holding circuit of relay R10 and to complete circuits of receiver magnets Ml ... M5 prepared by relays R11 ... R15 and of relay R17 which after a delay opens the holding circuits of relays R11 ... R15. The receiver is thus restored to its initial state.

[Class 38 (v)] In an electricity meter or other indicating or recording instrument wherein the meter mechanism drives a rotary member a so as to bring one' or more contacts c into engagement with stationary contacts o, in order to avoid the lack of accuracy of the instrument produced by the resistance to rotation of the body a owing to the frictional resistance due to the engagement of the contacts, the contacts are adapted to close an additional circuit to an electromagnet n which then attracts an iron bar e fixed to the rotary drum a. There is lost motion between the bar e pivoted at d and the arms h of the driving mechanism of the instrument so that when the magnet n is energized the bar e leaves the driving arm h and rotates till the contacts c, o become disengaged and the magnet circuit is interrupted. The meter mechanism continues to rotate till an arm h again reaches the bar e and drives it round till the next contact c engages a fixed contact. The drum a instead of carrying a contact c may have a projection which presses a contact spring into engagement with another contact spring.
