Title: A wire flattening mill
IPC: B21B1/16
Filed: 1947-07-08
Abstract: 632,336. Rolling. DECO MACHINERY Ltd., DAFT, H., and KIRK, W. H. July 8, 1947, No. 17943. [Class 83 (iv)] Wire is flattened between a pair of rolls and wound on to a bobbin provided with a traversing guide and driven through a slipping clutch. The bottom roll 4 is directly driven from fast and loose pulleys 5, the top roll being idle. The rolls are so mounted in a housing that, on removal of the top cross plate 51, they may be lifted out together with their bearings. The wire is guided to the rolls between fingers 53 laterally adjustable on a support 54 to provide both for varying the distance apart and the part of the roll surface to which the wire is fed. A dog clutch 49 on the lower roll drives through the compound chain gearing shown in Fig. 2, a shaft carrying a bobbin 10 and a shaft carrying a cam 16 with an endless track for a follower 17 on a bar 13 which is reciprocated causing a grooved pulley 14 to lay the wire evenly on the bobbin. An intermediate tensioning pulley 32 is carried by an arm 33 controlled by a spring 34. The chain wheel 45 drives the bobbin shaft through a friction clutch 37 adjustable by a spring 39 and locknuts 40. Slip is thus permitted as the effective diameter of the bobbin increases. Some of the chain wheels may be removable to enable the speed ratios to be varied. Detectors normally supported by the wire but gravity or spring biassed may operate through some form of servo-apparatus to release a clutch or shift the driving belt into the loose pulley should the wire break or the tension fail for any other reason. Preferably a brake is applied. The bar 13 may be traversed indirectly by the cam to permit the extent of traverse to be adjusted. In one form the cam reciprocates a bar parallel to the bar 13, the two bars being connected by pins and slots to a cross lever with an adjustable pivot. In another form the cam oscillates a lever adjustably linked to a second lever that reciprocates the bar.

Abstract: 1,215,046. Programmed control of machine tools. STARKSTROM ANLAGENBAU KARL-MARXSTADT. VEB. April 18, 1968, No.18398/68. Heading G3N. A numerical control system for controlling operations on a plurality of axes comprises a digital computer and an adjustable timing means for each axis whereby once instructions have been given by the computer an operation commences on each axis and is no longer controlled by the computer, until, by the timing mean associated with the axes, each operation is brought under control of the computer again just before the completion of the operation. As shown, a washing programme, on a punched tape, is read in by an input unit 1 and fed to a digital computer 2, having a calcuting, store and programme control sections connected to control command registers 4À1-4n for the machine axes. According to the time necessary for the programmed operation on an axis of a machine a pulse counter 3À1-3n is set so that it interrupts a subprogramme running in the computer shortly before the completion of the operation. The operation on the axis is then brought under control of the computer and a comparison of actual and desired position values in registers 4À1 -4n carried out until the operation is completed. To avoid chronological coincidence of two axes before the setting of a counter 3À1-3Àn the other counters are explored to ascertain whether a subprogramme would be interrupted, in which event the counter is switched on after a delay through the corresponding command register 4À1-4Àn.
