Patent GB-1064161-A (GB)
Title: An improved process for the production of crimped yarn
IPC: D02G1/00
Filed: 1964-05-20
Abstract: A process of crimping a monofilament or multifilament yarn comprises feeding an undrawn or incompletely drawn yarn - for example nylon or polypropylene - from a package to a set of crimping members or pins which with the yarn lying between them in a substantially zig-zag configuration, are moved towards and away from one another to deform and draw the yarn.  As described, yarn from a package is first drawn over a heater before passing to the pins which are secured on the circumference of, and parallel to the respective axis of, one of two discs which are mounted on skewed axes so that the circumferentially spaced pins on one disc intermesh with the pins on the other disc to provide a point of maximum separation and a point of maximum intermeshing displaced 180 DEG  from the first point.  After the maximum lateral distortion the yarn initially relaxes a little, but thereafter due to the grip of the pins on the yarn lessening any slack in the yarn is taken up by a ringtwister or other winding apparatus.  The yarn produced by this process has a high potential shrinkagee.g. higher than 8% -, a high potential crimp contraction upon exposure to heat, and, when viewed through a polarizing microscope, a uniformly interrupted fringe pattern.

Power factor for a load 10 (Fig. 1) fed from a source 11 over lines 13, 14 is measured by a bridge 19 comprising series assisting, e.g. germanium diode rectifiers 21, 22, 23, 24, of which one diagonal is fed with a saturating current from the secondary of a current transformer 16 whose centre tap is returned to the junction of line 14 with the primary in series therewith. The remaining diagonal shunted by a centre zero meter 36 is fed from the ends of a resistor 34 whose centre tap is energized in quadrature with the line current from a capacitance resistance phase shift network 31, 32 across the load.

Abstract: 1,087,338. Control circuits for multi-electrode arc welding apparatus. GENERAL ELECTRIC CO. May 21, 1965 [May 25, 1964], No. 21591/65. Heading H2H. [Also in Division B3] A control circuit for arc welding apparatus generally similar to Specification 955,247 and having a plurality of sequentially-energized electrodes 55A . . . 55E enclosed by a shielding chamber 59 comprises time delay relay coils TD1, TD2 which operate in a " flip-flop " manner and which respectively control the duration of welding current flow to a selected electrode and the time during which the workpiece 56 is allowed to cool. Energization of relay TD1 fires an ignitron 48 (through contacts CR3A) to cause the welding current source 50 and the high-frequency arcstarting supply 60 to be connected to the electrode 55A (at the commencement of a welding sequence) through a switch C1 After a predetermined time, relay TD2 is energized and the welding current is disconnected by the ignitron 48, after which the switch C1 is moved to the next electrode position by a stepping motor SM1 whose controlling relay CR4 is operable by a stepping switch SS1A associated with synchronously moving switches SS1B, SS1C of which the former controls indicator lamps 1 ... 10. Switch SS1C is connected to a manually-set switch D1 whose position determines the number of electrodes energizable in a welding sequence, the arrangement being such that when contacts 65, 68 coincide further operation of timer TD1 is prevented and switches SS1A, SS1B, SS1C, and C1 are stepped rapidly back to their initial positions to await a further operating sequence initiated by closing a start switch 47. The above-mentioned re-setting operation may be initiated by closure of a switch 70 should a welding sequence be interrupted by actuation of an emergency stop switch 46. The invention may be applied to control plasma arc welding, and may be modified so that the switch C1 does not have to break the high-frequency current from supply 60.
