Abstract: 1384142 Drawing BENTELER-WERKE AG 16 June 1972 [26 June 1971] 28282/72 Heading B3P  In a method of drawing a tube through a train of drawing dies 8 by an electric motor driven drawing drum for each die, the tube follows a substantially rectilinear path between the drums and the relative torques of the drum motors are controlled to maintain in the tube section 4a between each die 8 and the preceding drum a predetermined tension providing a counterpull. A steel strip (1) (Fig. 1, not shown) is skelped by rolls (2) and longitudinally welded by a device (3) to form a tube, which is continuously drawn through a number of dies 8 and finally coiled on coilers (7, 7a). The tube may be reduced 30- 50% in area at each die 8 and is passed around each drawing drum once only. Successive pairs of the drums are arranged at right angles to each other, the drums in each pair being positioned on opposite sides' of the tube. A constant counterpull is maintained in the tube section 4a by monitoring the tension in the section 4a by a dancer roll 24 which causes the speed of the motor of the drum 5a to be regulated. Each drawing die 8 is mounted in a holder 10 which is supported on a roller 14 and mounted on a horizontal hinge pin 11 rotatable about a vertical swivel pin in a bearing 12 to. enable proper alignment of the die 8. A floating plug (20, 20a, 20b) (Fig. 4, not shown) is arranged within the tube at each die 8, each plug except the last (20b) in the drawing direction having an axial bore (23, 23a) to allow the passage of lubricant supplied through a pipe (22). Lubricant is also introduced into the tube interior by a pipe (21) and into a sleeve 16 mounted in front of the die 8.

Abstract: 1500232 Data transmission MARCONI CO Ltd 2 May 1975 [4 July 1974] 29590/74 Heading H4P In a digital data transmission system of the type in which double adjacent errors arise during transmission, the errors are corrected by first converting each block of data bits into a codeword of N bits B 1  to B n , the bits B 1  to B n  being related to the bits P 1  to P n  of a codeword of any code, such as a BCH code, capable of correcting errors occurring at random. This relation is effected by making the ith term P i  equal to the sum modulo 2 of the first i terms B, to B i , so that when the codeword P, to P n  is recovered by cumulatively summing received bits B 1  to B n  and decoded to correct for errors occurring during transmission, the resulting computed bits constitute a word of the random error correcting code, with a single error for each error pair in the codeword B, to B n . Such errors can then be detected and corrected by standard techniques. The mathematical operation involved in the design of suitable encoders is described with reference to Figs. 5 to 10 (not shown).

Abstract: 1386597 Controlling extrusion cutting apparatus FREDERICK SQUIRE Ltd 23 June 1972 [24 June 1971] 29617/71 Heading B5A [Also in Division G3] In an electro-pneumatic control system, e.g. for controlling the cutting apparatus of Specification 1,386,596 cutting equal lengths of strip or rod material, current to a solenoid valve 7 is controlled by a timer switch 23, a normally closed micro-switch 26 and a switch device (e.g. a photo-cell device which closes when a predetermined length of material has passed a cutter head) connected to a plug unit 29. In operation, with a switch 15 closed to the right hand side the timer 23 after a preset delay, connects the solenoid to the live line L, assuming the external switch device is closed. The solenoid valve opens and air is passed from a duct 2 to a poppet valve 6 which is thereby opened passing air to the cutting machine via a pipe 1. In addition, air is passed via a valve 10 to a pilot cylinder actuator 11 which opens the micro-switch and de-energizes the solenoid. Valve 10 introduces a time-delay in the actuation of the micro-switch. Air supply is thus cutoff from the pipe 1 and actuator 11. After a further delay determined by valve 10 the piston of actuator 11 is retracted and the cycle is repeated. The delay introduced by the timer 23 is arranged to be sufficient to allow a cut length to fall away from the cutter. A counter 33 counts the number of cut lengths. The above arrangement is suitable where the feed rate of material is variable. If however the feed-rate is constant, the switch 15 is switched to its left-hand position (as illustrated) whereupon a timer 19 will control the solenoid valve 7 so that cutting occurs at constant intervals and equal lengths will be produced.
