Patent GB-816184-A (GB)
Title: Method and apparatus for guiding webs into positions of correct registration
IPC: B41F13/02
Filed: 1957-03-20
Abstract: 816,184. Automatic position control systems. MASCHINENFABRIK GOEBEL G.m.b.H. March 20, 1957 [March 20, 1956], No. 9208/57. Class 38 (4). In a method of controlling longitudinal web registration, the web is periodically stopped and clamped and the clamp support moved in a direction to correct the error. The web 1 is fed through drive rollers 2, 3 under a jockey roller 4, across a table 6 and through feed rollers 7, 8 to a processing machine 9. Signals from a photoelectric scanner or other type of web registering apparatus 11 are fed to control unit 12. During processing in machine 9 the web is arrested by clamps 10 and rollers 8 are raised to remove the drive. As rollers 2, 3 are in continuous motion the loop under roller 4 increases during this part of the operation, but decreases again when the web is fed into machine 9 prior to the next operation. The registration detector may operate just before or just after the web is stopped. In the former case, the web being in motion, a time comparison is made between signal pulses initiated by marks on the web and by a rotary contact device 13 in the machine 9. In the latter case the scanner detects a position error by the differing illuminations of a photocell. The error signal from unit 12 energizes one or other of electromagnetic clutches 15, 25 coupled to constant speed motor 17. This transmits drive through worm and nut mechanism 20-22 and leverage 24 to the table 6 which moves correctively along slides 14. A proportional movement is imparted to pivoted roller 4 to allow for the resulting web travel, and is also given to the differential cage 29 via rod 28. The latter movement alters variable ratio gearing 33'and so adjusts the speed of drive rollers 2, 3 to further compensate for web movement and to remove the source of the error. To limit the travel of table 6 switches 39, 40 are suitably placed and engaged by a projection 41. They energize a motor 42 which adjusts the driving roller speed so that an error of opposite sign will occur and cause the table to return to its normal position.

Title: Improvements relating to electrical computing instruments
Inventor: WALKER DONALD FERGUSON
IPC: G06G7/22
Filed: 1950-04-18
Abstract: 688,772. Electric analogue calculating systems. FERRANTI, Ltd. April 17, 1951 [April 18, 1950], No. 9426/50. Addition to 650,718, [Group XXXVIII]. Class 37. In an electrical computing instrument (Fig. 1) for solving triangles using the equation r<SP>2</SP> =p<SP>2</SP>+q<SP>2</SP> - 2pq cos R, as shown in Fig. 2 of Specification 650,718, [Group XXXVIII], the reversing auto-transformer 11 is replaced by a large resistance 80, approximately 2000 times the value of resistances 7 or 8 or the cosine potentiometer 14, which is connected between the junction of resistances 1 and 7 and the free end 84 of potentiometer 14. The input of a high gain amplifier 81 is connected between the mid-point 82 of resistance 80 and the common lead 6, and the output thereof is connected between point 84 and the junction of two neutralizing resistances 83, 85 in series between the junction of potentiometer 14 and resistance 8, and the common lead 6, so that the voltages developed at points 82 and 84, referred to the common lead 6, are phase opposed, and heavy negative feedback is applied across the amplifier. The remainder of the circuit is unaltered, and since the feedback maintains point 82 at approximately zero voltage, referred to the common lead 6, the voltage V 1  across resistance 7 develops a similar phase opposed voltage at point 84, so that the voltage developed between one end of the cosine potentiometer 14 and its mid-point 16 by voltages V 1  and V 2  across resistances 7 and 8 is ¢(V 1 +V 2 ) as described in the above Specification. The error in the voltage V 2  due to the voltage across potentiometer 14 applied to resistance 8 is corrected by the voltage developed by the amplifier across resistance 83, equal to that across the potentiometer, which causes a neutralizing current to flow in the resistance, and the neutralizing circuit constitutes a bridge network (Fig. 2) comprising potentiometer 14, resistances 80 and 7 in series, resistance 83 equal to the potentiometer; and resistance 85 adjustable for balance; the amplifier output being connected to one diagonal and resistance 8 to the other. The device is applicable to artillery and navigational computation.
