Title: Improvements in or relating to yarn packages and processes for winding such packages
Inventor: ROLLASON CHRISTOPHER JOHN
IPC: D01F6/60
Filed: 1967-11-17
Abstract: 1,242,223. Winding processes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 13 Nov., 1968 [17 Nov., 1967], No. 52486/67. Heading D1F. [Also in Division B8] Freshly drawn, single or multifialment, continuous strand or yarn of polyamide is wound, in parallel layers with a long to short build, to form a package, at different balloon (windon) tensions, caused by changes in spindle speed, so as to counteract the forces which develop in the package subsequent to building. In an example, the spindle speed is programmed to give balloon tension starting at one gram, increasing to eight grams at one third of the full package, and then decreasing to one gram again at the full package, the corresponding spindle speeds being 8,500 r.p.m. increasing continuously to 9,200 r.p.m., then decreasing continuously to 5,700 r.p.m. On subsequent unwinding, the shrinkage tension (the tension which occurs when the yarn is held to constant length and heated to a temperature of 190 5C) varies about a mean by not more than 5%, with consequent reduction in dyeing differences in bulked yarn fabrics made from the unwound yarn.

Abstract: 1450963 Chopper control in D.C. motor circuits HITACHI Ltd 27 Nov 1973 [4 Dec 1972] 54980/73 Heading H2J [Also in Division H3] A D.C. motor control circuit comprises the motor 2 and a thyristor chopper 3 in series therewith of the type having a main thyristor 4 and an auxiliary thyristor 5 and commutation capacitor 7 for turning off the main thyristor, the system employing power source 1 supplying current to oscillator 13 which produces a rectangular wave of constant frequency which is passed firstly to a "chopper-on" signal generator 21 to provide triggering pulses to main thyristor 4, and secondly to a differentiating circuit 35 to provide "chopper-off" pulses to the auxiliary thyristor 5, and also comprises a detector consisting of Zener diode 46 and transistor 48 to prevent the "chopper-off" signals reaching the thyristor 5 when the chopper is not conducting. This provides finer control at low motor speeds since otherwise the chopper would be enabled via the auxiliary thyristor during the turn-off pulse period, and this would prevent the mean motor current from falling below a particular level. The device 21 comprises a magnetic phase shifting device 25 having coils 24, 23 fed with a signal indicative of the motor current and of a desired motor current respectively. The leading edge of each output square pulse is retarded more or less according to a comparison of these two values to provide pulses of variable duration, the thyristor 4 turning on at each leading edge of the output pulses from device 21, these pulses ending coincidentally with the unmodified pulses from oscillator 13. The "chopper-off" signal is generated coincidentally with every edge of the pulse train from oscillator 13. If the chopper is off, i.e. the "on" pulse has a zero duration, the pulses from the differentiator 35 are shorted to earth via transistor 48 which is rendered conductive in this event.
