Title: Improvements in and relating to the production of wound yarn packages suitable for use in knitting operations
IPC: D01D10/04
Filed: 1949-02-15
Abstract: Yarn is obtained in a condition suitable for use in knitting operations by twisting the yarn while winding it on to a hollow perforated holder, subjecting the wound yarn package to a twist-setting treatment, and exposing the package, before or after the twist-setting treatment, to a mist of fine particles of a lubricant whilst the pressure within the holder is reduced, so that lubricant is drawn into the package and spread over the surface of the yarn.  The yarn may be made of natural or synthetic fibres, e.g. viscose rayon fibres.  The lubricant may be a <PICT:0669191/IV (c)/1> mixture of sulphated arachis and white oil.  It should be in the form of very fine particles floating in the air.  The perforated holder may by a cylinder, e.g. of papier mach<\>ae, and it may be open at both ends during the twist-setting operation.  This operation may be effected by placing the holder in a steam cabinet or by exposing the wound package to an electric field of high frequency.  During the lubricating step one end of the holder is closed and the other end is fitted on to a suction pipe.  A number of wound packages may be placed on a conveyer which carries each package through an atmosphere containing a mist of lubricant whilst the air is being withdrawn through the holder.  As shown, the yarn package 1 wound on perforated tube 2 is exposed in chamber 12 to a mist of lubricant whilst the pressure is reduced within tube 2.  A suction-pipe is connected to the interior of tube 2.  A platform 7 carried on rollers 10, 11, forms a movable base to the chamber 12.  The yarn packages may thus be mounted on the platform 7 outside the chamber and then carried through it. The chamber may be closed at each end by doors and at each side by flexible strips 13, 14.  The platform may form part of a circular table or a continuous belt, and its movement may be continuous or intermittent.  Lubricant is injected through jets 15, 16, to form a mist.  It may be atomized by passing through a single small hole of diameter 0.009 inch in each jet.  Specifications 297,000 and 320,025, [both in Class 15 (i)], are referred to.

Title: Improvements in or relating to crepe threads and fabrics containing artificial filaments
IPC: D02J1/22
Filed: 1934-02-08
Abstract: Crape threads are formed by applying to artificial yarns, comprising organic derivatives of cellulose, an organic softening agent for the substance thereof, stretching the yarns beyond their elastic limit uniformly along their length, and subsequently imparting to the yarns a high degree of twist; if desired, wet spun cellulose derivative yarns may be stretched to the desired degree during coagulation in a bath containing the organic softening agent.  The yarns may be stretched in the presence of aqueous formaldehyde and to at least 120 per cent of their original length and may be subjected to a shrinking treatment, e.g. as described in Specification 380,504 after the stretching operation.  The yarns may be subjected to a partial saponification treatment, e.g. as described in Specifications 316,521 and 318,468, [both in Class 2 (ii)], after the stretching operation.

Title: Variable frequency oscillators
Inventor: WILLIAMS JOHN LLEWELLYN
IPC: H03B27/00
Filed: 1965-02-05
Abstract: 1,136,481. Transistor oscillating circuits; automatic frequency control systems. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 1 Feb., 1966 [5 Feb., 1965], No. 4395/66. Headings H3A and H3T. [Also in Division H2] A multi-phase variable frequency oscillator comprises a number of substantially identical variably tuned active stages coupled together in a closed loop by phase-shifting networks. Each of the transistors 37, Fig. 1, has as collector circuit the parallel-connected primaries of a pair of saturable - core transformers 35, the corresponding secondaries being connected in series to provide one phase of a three phase output: the frequency is controlled by variation of the D.C. in series-connected control windings 61, the windings for each pair of transformers being so connected as to balance out A.C. components. The transistors are coupled together, to form a three-phase oscillator, by similar R.C. phase-shifting networks 36, 39. A push-pull version of the oscillator is also described in the Specification (Fig. 2, not shown). Automatic frequency control.-The output of one phase of the oscillator is fed to a network comprising series resistor 62, Fig. 3, and reversely-poled rectifier diodes 67 and Zener diodes 66 to produce a square wave of constant amplitude which is fed via capacitor 68 to one transistor 78 of a differential amplifier comprising transistors 78 coupled by a common emitter resistor 79. A stabilized potential is applied to the other transistor 78 from Zener diode 76 and adjustable potentiometer 75, and a control potential is derived from the collector circuit resistor 80 and applied to vary the base bias of a further transistor 81, the collector current of which comprises the current through all the transformer control windings 61. Alternatively, the differential amplifier may be replaced by a single transistor with the stabilized voltage applied to its base and the oscillator output also applied thereto via a current limiting resistor, the base being connected to earth via an integrating circuit and a rectifier diode.

The member 1, which is generally cup-shaped, has a peripheral wall 10 provided with equi-spaced slots 13 to allow the escape of the propellant gases from a rocket 46 seated on a step 14 within the wall 10. A rod 15 screwed into the wall 10 passes through a ring 47 on the rocket and guides its initial travel. An electric socket device 16 is secured in the base of member 1 and comprises an insulated metal socket 20 from which extends a contact 21 abutting a contact 32 of a dry cell 30 itself in contact with a cell 31 supported by a spring pressed plunger 33 within the grip 2. The dry cells are housed in a metal sleeve 27 closed at its lower end by an insulating plug 36 and surrounded by a sleeve 37 of synthetic resin supported by a spring 38 bearing against a collar 39 secured by a grub-screw 40. A casing 41 of synthetic resin forms the outer cover of the hand grip 2. By pressure on a knob 44 extending throrgh a slot in the casing 41, the sleeve 37 can be retracted, whereupon by squeezing a trigger 22 mounted on the receiver 1, a contact button 26 is moved through an opening 45 into contact with sleeve 27, to complete the circuit through an electric igniter placed in the device 16 and so fire the rocket 46. An annular disc 48 may be clamped between receiver 1 and the sleeve 3 to protect the hand holding grip 2. Instead of being held in the hand the devce may have a base for mounting it on a support or on the ground.

Title: Making glass fibre articles

Abstract: 1,144,020. Moulding reinforced resin articles. GENERAL MOTORS CORP. 1 Feb., 1968 [16 Feb., 1967], No. 5228/68. Heading B5A. [Also in Division F2] Reinforced synthetic resin articles are formed by impregnating glass fibre rovings with liquid synthetic resin, flexing and bending the rovings to wet them with the resin and expel air, heating the rovings, forming them into a mass and moulding the mass to the desired shape. The rovings are preferably under tension during impregnation, and the tension is removed before moulding. The resin may be phenolic, a polyester or an epoxy and preferably forms 24-30 wt. per cent of the finished article. As shown, impregnated rovings 10 pass over and under steel rods which cause them to bend and flex. Excess resin is removed at the outlet end of the bath and the rovings which are still separate, are heated in oven 16 to the temperature at which the resin has minimum viscosity, assisting the removal of air bubbles. The rovings are pulled through an open-ended die 18 causing them to form into one mass and the mass is shaped under heat and pressure between dies 56, 54 after relief of tension by rollers 48 and 50. The process may be used to form leafsprings.
