The front rail 4 similarly has flanges 17, 18, the upper flange 18 having a backwardly bent portion 19 to which the front cover is secured by rivets 20, which also secure a. metal guide 21 for a title strip 23 and covering transparent sleeve 22. A flexible spine cover 24 may be secured by the rivets 16, 20 or other means. The hook members 10 may be formed from a plate 25 of hook shape, riveted to the ends of the channel part of the rails, and the protruding part of the hook is covered with rubber or flexible plastic 26 to form a buffer and the lower edge is turned over at right angles at 27 to form a rounded bearing surface. As shown in Fig. 6, papers 38 are clamped between bars 37 by means of a cord 39 and friction grips 40, the bars 37 being threaded through pockets 36 on strips 32 folded inwardly from stiff paper board covers 31.

Title: Improved roll system for the treatment of artificial filaments and yarns
IPC: D01F6/62
Filed: 1947-10-01
Abstract: <PICT:0633455/IV (a)/1> In a roll system for the drawing and relaxing of an artificial yarn or filament, the relaxing rolls are replaced by a non-driven tension device which makes use of the balloon tension engendered in the yarn or filament by the rotating cap or traveller of a cap or ring spindle, to apply a relaxing tension to the yarn. In the Figure, the yarn 1 is drawn by passing it between rolls 2 and 3, round pin 4 and then three times round rolls 5 and 6.  The yarn is then relaxed by passing it over hot-plate 7 to the tension device 8, which may consist of two pins through which the yarn passes, and through a lappet eye 9 to a yarn package 10 mounted on a ring p spindle.  The amount of relaxation may be varied by increasing or decreasing the arc of contact the yarn makes with the two pins. In an example, polyethylene terephthalate yarn is hot drawn with the pin 4 at 80 DEG  C. and then relaxed using the hot-plate 7 at 200 DEG  C. Specification 578,079 is referred to.

Abstract: 1,255,210. Control systems for magnetic chucks. A. K. LITTWIN. 27 May, 1969 [26 June, 1968], No. 26773/69. Heading H2H.  Apparatus for magnetizing and demagnetizing a magnetic device such as a magnetic chuck for a machine tool comprises means whereby the device is demagnetized in discrete steps, in each step the direction of the demagnetizing force is reversed and reduced. A magnetic chuck comprisesa permanent magnet member associated with an electromagnetic winding which is fed from a three-phase A.C. source by way of a transformer, a pair of reverse-parallel connected thyristors, a rectifying bridge and the contacts of a relay having two stable states. To magnetize the chuck a push-button is provided which when operated controls the thyristors. to conduct for maximum periods thereby fully magnetizing the chuck. A second push-button is provided which when operated initiates the demagnetizing cycle of the chuck. The control circuit for the demagnetizing operation includes a stepping switch and a number of stepped biasing resistors, the operating members of which are ganged and driven by a solenoid. The solenoid is controlled by a relay itself controlled by two auxiliary relays and a timing circuit including capacitors, resistors and thyristors. Initiation of the demagnetizing cycle operates the relay causing its contacts in the chuck circuit to reverse the current supply thereby reducing the magnetization of the chuck to zero and magnetizing the chuck in the opposite direction. At the same time the solenoid is operated to step the stepping switch and biasing resistors one step thus the opposite magnetization of the chuck builds up to a level reduced from the prior magnetization. This is effected by the bias produced by the biasing resistor on the firing of the reverse parallel connected thyristors in the chuck supply circuit. The opposite magnetization is sensed by a transformer and the relay is then caused to once more reverse its contacts and the solenoid operated so that the demagnetization continues until the cycle is complete.
