Title: Production of variably bulked yarns
IPC: D02G1/20
Filed: 1962-06-14
Abstract: 1,005,592. Bulked yarn and fabrics; knitting and weaving. JOSEPH BANCROFT & SONS CO. June 14,1962 [June 30, 1961(2)], No. 22983/62. Headings D1C, D1E, D1F, D1J, D1S and D1W. A variably bulked yarn of continuous filaments of a heat-settable material-for example nylon-is made by tensioning the filaments, when crimped, sufficiently to pull out at least part of the crimp and heating selected lengths only of the filaments to set these lengths in a non- or partially crimped form, and thereafter relaxing the filaments to restore the crimp in the non-selected lengths. The yarn may have been bulked by means of a stuffer box, air jet, false twist, or by being drawn over a sharp edge, and treated-as by heatto set the crimp. Selected lengths of the yarn may be heated by means of fingers 16, Fig. 1 (not shown), which are controlled, through a solenoid, by a programmer which press there lengths against a heated shoe; by passing the yarn across heated cylinder 41, Fig. 2, so that the yarn only contacts the spaced bosses 46, the cylinder being reciprocated to carry the degree of contact; by causing the yarn path to reciprocate across the heated serrated edge of a bar 57, Fig. 3 (not shown) by means of a guide which also causes the yarn to be traversed across the wind-up package; or by heated arcuate rods 64, Fig. 5 (not shown) which press against a yarn package as the yarn is unwound therefrom. Alternatively the yarns may be in the form of a warp sheet being fed to a weaving on knitting machine, with a series of cams 115, Fig. 9 (not shown) mounted on a shaft pressing certain areas of the sheet against a heated shoe; or in the form of a woven or knitted fabric which is passed before being relaxed either over a heated roller having raised pattern sections 211, Fig. 12 (not shown), or together with a stencil 224, Fig. 15 (not shown), under a radiant heater.

Title: Improvements relating to electrical control equipment
Inventor: COLLING JOHN ANTHONY
IPC: G05D16/20
Filed: 1961-06-30
Abstract: 934,120. Automatic pressure control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 19, 1962 [June 30, 1961], No. 23743/61. Class 38 (4). In a system in which change in length of a resistor with change in temperature due to change in ambient pressure operates auxiliary contacts controlling main contacts, a different current is passed through the resistor according to whether the auxiliary contacts are open or closed. As shown, a resistor W located in a vacuum chamber is heated by alternating current supplied through contacts B1, and a pump V exhausting the chamber is operated by current through contacts B2. When pressure falls below a limit determined by the setting of a rheostat R1 the rise in temperature of resistor W due to its lower rate of cooling causes it to expand sufficiently to move a lever D about a pivot G to close contacts E1, E2 and energize a D.C. relay. RLA. The operation of relay RLA energizes a relay RLB to open contacts B2 and stop the pump. The operation of the two relays changes over the positions of contacts A1, B1 causing a greater heater current to pass through resistor W so that the relays do not reset to start the pump again until pressure has risen to a value determined by the setting of a rheostat R2. A slight time delay between the operation of the two relays assists positive operation.
