Title: Improvements in or relating to apparatus for the production of crimped or bulk yarn
IPC: D02G1/12
Filed: 1959-03-05
Abstract: 930,069. Crimping yarns. KLINGER MANUFACTURING CO. Ltd., and D. A. E. MATTINGLY. June 7, 1960 [March 5, 1959], No. 6122/59. Class 120 (3). Yarn crimping apparatus comprises a pair of rollers which feed the yarn into a bight therebetween on the delivery side thereof and a member which projects into the bight to engage the yarn and continuously travels the length of the bight at a speed less than the peripheral speed of the rollers so that yarn is withdrawn from the bight, to winding apparatus, at a slower speed than it enters and is thus bunched i.e. crimped or compressed in the direction of its length, in the bight. A part of the apparatus e.g. one or both rollers, which engages the yarn whilst bunched is internally heated to set or partially set the yarn. Additional heat setting may be effected after the yarn leaves the member. As shown, yarn 11 is fed by driven, spring- loaded rollers 13, 14 to the nip of driven, spring- loaded, hollow rollers 30, 31, which are heated by electric coils, as at 37, supplied through slip rings, as at 41, 42. The bristles of an adjustably positioned, gear-driven wire brush 46 extend into the bight of rollers 30, 31 and is rotated at such a speed as to cause the yarn to bunch and also to direct crimped yarn over a heated surface 51, between nip-rollers 52, 53, rotating at such speed as partly to pull out the crimps in the yarn, to a bobbin 59 which is driven by roller 58 at such a speed as to straighten the crimp. The brush 46 may be replaced by a rotating disc or an endless band e.g. of strip metal, the edge of which projects into, and extends along the length of, the bight of rollers 30, 31. The edge may be so shaped that its surface may be positioned closely to the roller surfaces and it may be concavely curved in cross-section; the disc edge may be blunt e.g. with a narrow cylindrical surface; the edge surface of the band may be flat. The diameter of the disc or brush may be larger than the diameter of the rollers. Specification'885,473 is referred to. Reference has been directed by the Comptroller to Specification 873,368.

Title: A one-piece rail anchor adapted to prevent creepage of doubleheaded and like rails, and to lock the chair wedges
IPC: E01B13/02
Filed: 1924-03-11
Abstract: 228,093. M. B. Rail Anchor Proprietary, Ltd. Jan. 23, 1924, [Convention date]. Creeping of rails, preventing. - A onepiece anchor for double - headed rails grips the inverted head so that there are three grips on the rail and @@ch gripping- means is carried on a spring arm. The anchor is recessed at 3 to grip the edge of the inverted head 4 and passes under and across the rail in a slightly rearward direction and is then turned forwardly and extended upwardly to form a T- shaped portion 5. The rear arm 7 of the T- head forms a grip bearing on the bevel of the inverted head. The forward arm is extended downwardly and outwardly to form a grip on the edge and bevel of the inverted rail and also an abutment 6 for the wedge of the rail chair. According to a modification the anchor on the side of the single grip is rearwardly and outwardly extended so that it may be placed in reversed position on a rail so as to clear the wedge. According to a further modification the rear arm may be extended and turned outwardly to form an abutment which will bear on the chair wedge if the anchor is placed on the rail in a reversed position.

Title: Improvements relating to electrically driven slicing machines
IPC: B26D7/22
Filed: 1926-03-06
Abstract: 270,854. Berkel & Parnall's Slicing Machine Manufacturing Co., Ltd., and Thomas, H. March 6, 1926. Driving-arrangements.-An electrically driven slicing-machine is so arranged that it is impossible for the motor to be clutched until it has been switched on at the machine or to be - switched off at the machine before the clutch has been disengaged. The. countershaft B operating the reciprocating carriage through a pinion E .carries loosely a sprocket wheel A driven in the usual manner from the slicing-machine shaft. The sprocket wheel is formed with one element 0 of a clutch and co-operates with a clutch element O<1> fixed on the countershaft. A spring H normally keeps the clutch elements in engagement and control of the clutch is effected by a pivoted lever F. A brake may be provided comprising a washer L between a collar on the countershaft and loose ring K and when the lever F is rotated clockwise. the brake is released and the clutch element 0 moves into engagement. with the element 0<1>. For operating the clutch and the switch, a lever 0 is provided, one arm O<1> of which moves between the arcuate bars S of a gate or quadrant. The bars S are formed with three pairs of notches 9, 10, 11 and the spring-retracted handle R on the arm 0<1> carries a pin 12 to engage with the notches. The lever 0 also has a clutchoperating arm comprising a cam face N with which co-operates an adjustable stud M on the lever F, and an arm 8 which actuates the motor switch T through a pivoted lever 3. When the handle is moved from the inoperative position 9 to the position 10, the switch T is closed, but by reason of the shape of the cam face N, the clutch arm remains stationary. In order to give the motor time to attain its full speed before the clutch is actuated, the bars of the gate are formed with recesses 14 of such a shape that some manipulation of the handle R is necessary in the position 10 before an abutment 13 thereon can clear the uppermost slopes of the recesses, and the necessary delay is thus obtained. As the handle is moved into the fully operative position 11, no further movement of the switch lever 3 occurs, but the cam face N permits the lever F to move under the action of the spring H so that the brake is released and the clutch operated.

Filed: 1948-03-05
Abstract: 643,294. Frequency mediation; valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. March 5, 1948, No. 6865. Convention date, March 8, 1947. [Classes 40 (v) and 40 (vi)] An oscillation generator, of the kind in which the frequency is adjusted by a variable resistance, employs a resistor of bismuth, tellurium, or other metal or alloy exhibiting the Hall effect, its resistance being varied by control voltage applied to a surrounding solenoid. As shown, a pair of valves 3, 4 are reciprocally coupled by resistance capacity circuits, and the grid circuit of the valve 3 includes a resistor R2 and capacity C<SP>2</SP> in parallel. The resistor R2 is formed of the above-mentioned material, and is surrounded by a coil 1 to which a modulating voltage is applied. Variation of the resistance of R<SP>2</SP> alters the phase angle of the network and modulates the frequency of the oscillations produced. In a modified circuit (Fig. 2, not shown), in order to allow a less fragile resistor of lower resistance to be used, the resistor is connected to the low-voltage secondary of a transformer, the high voltage primary of which is connected across the grid circuit of the valve 3. The oscillations may be stabilized by connecting a resistor 6 between the anode of valve 4 and the cathode of valve 3, and by inserting in the cathode lead a resistor 5 such as an incandescent lamp filament possessing a suitable temperature coefficient.

Title: Improvements in or relating to the homo-polymerisation of tetrafluoroethylene
IPC: C08F114/26
Filed: 1961-02-27
Abstract: A process for the production of polytetrafluoroethylene granular powders comprises contacting tetrafluoroethylene with an aqueous polymerization medium containing an inorganic redox initiatior system and 0.02 to 2 p.p.m. by weight of copper ion at 30 DEG  to 80 DEG C. and 0.6 to 4 atmospheres absolute.  Specified redox systems are ammonium and alkali metal persulphates/bisulphite which is preferred; other systems such as periodate/bisulphite and hydrogen peroxide/sulphite are stated to be less effective. The system may also contain an inert halogenated organic dispensing agent e.g. ammonium perfluorocaprylate and a buffer, e.g. borax, to maintain the pH constant and preferably alkaline. The process may be carried out batchwise, semi-continuously or continuously while monomer and polymer may be introduced and withdrawn incrementally. In a preferred embodiment portions of polymer are withdrawn together with some of the aqueous medium and contacted with further monomer in the absence of further catalyst to give a product of higher molecular weight. Granular powders are defined as having a surface of 1 to 4 sq.m./g. measured by nitrogen adsorption.
