Title: A method and apparatus for drawing and winding a thread
IPC: D01D7/00
Filed: 1969-04-24
Abstract: 1,271,718. Drawing and winding artificial yarns. MASCHINENFABRIK RIETER A.G. 24 April, 1969 [24 April, 1968], No. 20894/69. Heading B5B.  Apparatus for drawing and winding a single filament yarn or a multifilament yarn supplied from a spinning cabinet comprises a group of rolls 12 and a thread guide 16 traversing in a horizontal path forming part of a winding device 17. The horizontal distance BC between the extreme positions of the thread traversing over the length H of the wind-up roll is not greater than one-sixth of the vertical distance from the point where the yarn leaves the roll 15 to the line BC. A bundle of undrawn filaments are withdrawn from the lower end of a spinning cabinet 2, are collected by a guide 5 to form a multifilament yarn 4 which is caused to travel vertically downwards to a driven roll 6 which with roll 7 constitutes a pair of rolls 8 along which the yarn advances in a number of wraps due to the axes of the rolls converging slightly towards the free ends of the rolls. Pairs of rolls 9, 10 and 11  similar to the pair of rolls 8 constitute a group 12 of pairs of rolls extending upwards from the lower to the upper part of the apparatus. Each roll is provided with an internal heating device. The yarn leaving the roll 7 near its free end 14 is forwarded to the left hand roll of a roll pair 9 (Fig. 1) arranged above the roll pair 8. The roll pair 9 are driven at a peripheral speed higher than that of the roll pair 8 whereby the yarn in its passage from roll pair 8 to roll pair 9 is drawn at a draw ratio of 2 : 1 to 4 : 1. The axes of the pair of rolls point upwardly at an angle of 4 to 10 degrees to the horizontal (Fig. 2). After advancing in a number of wraps around the roll pair 9, the yarn is forwarded from the free ends of the rolls to a further pair of rolls 10 which are driven at a higher peripheral speed than the roll pair 9 whereby the yarn is further stretched at a stretch ratio of 3 : 1 to 6 : 1. After advancing from the inner to the free ends of the pair of rolls 10 in a number of wraps, the yarn is forwarded to a pair of relaxing rolls 11 driven at a peripheral speed lower than that of the rolls 10, whereby the yarn is relaxed. After advancing from the inner to the free ends of the pair of rolls 11 in a number of wraps the yarn is then forwarded from the right hand roll 15 of the roll pair 11 downwardly to the horizontally traversing thread guide 16 of known construction forming part of the winding device 17 arranged below the group of rolls 12. Two traversing and winding mechanisms may be arranged side by side below the lowest pair of rolls. Two winding arrangements, each provided with two traversing guide mechanisms traversing parallel with the roll axes and with corresponding drive rolls and bobbins may be arranged below the rolls, the winding arrangement being vertically offset with respect to each other (Figs. 3-7, not shown).

Title: Improvements in or relating to a method and apparatus for magnetic recording
IPC: H04N5/782
Filed: 1952-08-21
Abstract: 748,996 Magnetic recording and reproducing heads. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 21, 1952 [Dec. 31, 1951], No. 21006/52. Class 40(2) [Also in Group XIX] Successive electrical pulses are recorded on a moving magnetic medium (e.g. a wire or tape, not shown) by applying alternate pulses to opposing windings 15a, 15b of a recording head 15 whereby each pulse is recorded by subjecting the medium to a flux in a changed direction. In the recording apparatus, the windings are energized by electron discharge means under control of a bistable electric trigger. As shown in Fig. 4, pulses to be recorded are applied at terminal IN to the bistable trigger pair V5, V6 the anode outputs of which are taken via lines 9, 10, directly and through inverter V9 respectively, to the control grids of pentode drivers V10, V11 connected to the windings 15a, 15b. Either V10 or V11 is conducting so that magnetic flux is generated continually, in one direction or the other according to the condition of the trigger which is switched over by each input pulse. To prevent recording, a relatively positive potential is applied to line 12 which causes inverters V7, V8 to conduct to apply permanent negative potentials to the control grids of both V10 and V11, and to set the trigger pair in the starting condition with V6 conducting. When a binary representation, e.g. "yes" and "no," is to be recorded, two separate tracks are used. The reading' circuit, Fig. 5, comprises opposed windings 16a, 16b connected to triodes V1, V2 arranged to feed in pushpull two pentodes V3, V4 having a common return anode circuit including a relay RL-1. Thus the relay will be energized by change of flux in either direction sensed by reading head 16.
