Title: Effect yarn and textile fabrics made therefrom
IPC: D01D5/42
Filed: 1963-08-29
Abstract: 989,590. Yarns and threads. DOW CHEMICAL CO. Aug. 29, 1963 [Sept. 19, 1962], No. 34187/63. Heading D1W. [Also in Division B5] An effect yarn consists of or contains an oriented, thermoplastic, microporous filamentary material which has densified or compressed areas and undensified or uncompressed areas, the microporous filamentary material, which may be pigmented, being a microtape having a labyrinthian cross-sectional configuration. Said microporous filamentary material may be a foamed or expanded extrudate, and the densified or compressed areas may be formed by the application of pressure to intermittent, selected areas of the material prior to orientation. Elevated temperatures may be used during the application of the pressure. Specified materials include interpolymers of vinylidene chloride with one or more other ethylenically unsaturated monomers, especially acrylonitrile or lower alkyl acrylates e.g. ethyl, acrylate and butyl acrylate, or with vinyl stearate, styrene, vinyl oxazolidinone or methyl vinyl oxazolidinone, vinyl chloride, vinyl acetate, vinyl propionate, cycloalkyl and aryl acrylates, acrylic acid, acrylamide, vinyl alkyl ethers, vinyl alkyl ketones, acrolein, allyl esters and ethers and chloro-propene. Textile fabrics, woven or non-woven, may be made incorporating the effect yarn. In woven fabrics the effect yarn may form either the warp or the woof or both. In preparing the microtapes, the latex is continuously coagulated into a coherent coagulum which is washed, slit into tapes, dried, faced, shaped and oriented. Alternatively, microporous, thermoplastic filaments useful in the invention may be made from the above materials, or from an intimate powder mixture of vinylidene chloride polymers with minor amounts of trisodium aconitate, by melt-extrusion through a die to form filaments which are then orientated by stretching. In a preferred method, microtapes which have been folded, rolled or wound to the cross-sectional shapes of Figs. 3-7, or flat ribbons which have been plaited are passed through the nip formed between the groove of the grooved shaping roll 12, which may be heated, suitably to 170-205‹C. and the intermittent tape contacting roll 13, to produce a spaced densification effect on the microtape, oriented and collected.

Title: Universal joints
IPC: F16C33/78
Filed: 1956-11-09
Abstract: 842,100. Universal joints. GELENKWELLENBAU G.m.b.H. Nov. 9, 1956 [Sept. 1, 1956], No. 34281/56. Class 80 (2). [Also in Group XXVI] An inner sealing ring 5 held between a shoulder 6 on a universal joint trunnion 1 and a bearing bush 2 has a frusto-conical face engaged by a mating outer sealing ring 7 axially movable in the trunnion cap 4, rotation of the joint causing centrifugal force to act upon the outer sealing ring and engage it more firmly with the ring 5. The outer sealing ring 7 may be biased to engage the inner ring 5 by a spring 9 or may be retained in the trunnion cap 4 by a circlip 8. The outer ring may be segmental and may be made of a phenolic resin, a polyamide, a metal or of graphite.
Patent GB-1058551-A (GB)
Title: Improvements in and relating to the production of bulky yarns
Inventor: GARNER STEPHEN JOSEPH
IPC: D02G1/16
Filed: 1962-09-07
Abstract: Slubbed, bulky yarn is produced by feeding at least one (so-called "core") bundle comprising cotinuous filaments (or yarn(s) thereof) to a turbulent air zone, separately feeding intermittently, perhaps at random intervals and/or at varying rates, at least one (so-called "effect") bundle comprising staple fibres (or yarn(s) thereof) to the zone, and withdrawing all the bundles therefrom as a single assembly. The continuous filaments and the staple fibre may be of regenerated cellulose, cellulose acetate, polyamide, polyolefin, polyester, or acrylic polymer or staple thereof, wool or cotton, and of similar or different colour and/or material.  A "scaffold" thread (which is undisturbed by the action of the turbulent air) may be incorporated as part of the continuous filament bundle or by twisting it with the bundles after they have left the zone.  The intermittent feed may be obtained by moving the bundle into and out of gripping engagement by feed rollers, or by passing the bundle through a tensioner and a pair of rollers which are grooved or not circular in cross-section so that, during relation of the rollers, the bundle is alternately gripped and released.

Title: Motor vehicle power transmission mechanisms and controls therefor
IPC: F16H61/02
Filed: 1935-10-03
Abstract: 463,684. Change speed gearing. GENERAL MOTORS CORPORATION. Oct. 3, 1935, No. 34533/36. Convention date, Oct. 8, 1934. Divided out of 463,643. [Class 80 (ii)] Change-speed gearing for vehicles comprises three units in series, one R, Fig. 4, for selecting neutral, forward, or reverse drive, another unit M under manual control for a change of driving- ratio, and a further unit A for effecting a change of ratio under the control of a speed-responsive device or governor 211, Fig. 18, there being a unitary control means or lever 232, Fig. 1a, on the steering column for the reverse and manual units. The description is the same as in Specification 463,643. The units M and A in the arrangement shown are planetary and controlled by alternative plate clutches and wrapping band brakes. The unit M has stepped planets 71, 72, Fig. 4, connecting an intermediate shaft 32 to a driven shaft 64. This unit is in low speed with the brake 74 applied unless a slide valve 140<1>, Fig. 18, has been shot over to the left from the position shown so that pressure oil entering at 136 can pass up a duct 1451 and along another 1431 to depress a piston 1381, Fig. 10, and so release the brake 74, Fig. 4, and engage clutch packs 46a, 46b so that the unit M turns solid on high speed. The valve 140<1>, Fig. 18, is opened, and normally held open for low speed by a spring 1641 acting on a toggle 157<1>, 158<1>, the fixed pivot of which is at 156<1>. To change the unit M to high, a lever 192 is rotated clockwise about its pivot shaft 186 so as to extend the bias spring 1641 until a toggle spring 160<1> effects the quickthrow-over of the valve. The turning of the pivot shaft 186 is done by pulling a rod 190 left of Fig. 10. That is, to change up in the unit M a rod 225 is pulled left of Fig. 10 and upwards of Fig. 1a. The changing of the unit M is between points " High " and " Low " of a quadrant 235<1>, corresponding to the movement of a bowl lever 250, Fig. 10, upwards from the position shown and with lost motion clear of a fork 254 for operating the reverse unit R. To bring in reversed drive, the lever 232 is moved to position "REV," Fig. 1a, which brings the bowl 251 from the neutral position shown in Fig. 10 down to position 251<11>, and owing to a lever 226 passing over a dead centre, the pivot control shaft 186 of the unit M is not then operated. When the hand lever 232 is moved onto position " 3rd," Fig. 1a, an over-riding downshift in the unit A is imposed as described in the Specification referred to, this unit being normally controlled by the governor 211, Fig. 18, acting at one fulcrum 169 of a floating lever 166 and by the accelerator (not shown), acting at another fulcrum 175 so as jointly to control the valve 140 of the servomotor 138 of the unit A. A booster valve is described with reference to Figs. 15-17 (not shown), to prevent the wrapping brakes 74, 42 of the units M and A from being unwound during the reversed drive.

[Class 98 (ii)] [See also Group XXXVIII] Synchronization marks are provided on picture and sound films (for use, for example, when a sound record is pro. duced to accompany synchronously a previously prepared picture film) by making on one of the films, whilst it is still in the form of blank or "raw" material, a number of different synchronization marks that are located preferably at regular intervals along substantially the whole length to be recorded, and transmitting the marks to the other film or films in such a manner that they are separated from the records made on these films. The Figure shows a blank film provided along a margin with perforations 1, 2 similar to Morse signal indications. The markings enable corresponding parts of the negative sound and picture films to be cut out before the production of a combined positive film. Synchronization marks may be made by applying suitable colouring matter to an unexposed sensitized emulsion. As the marks are exposed to light whilst being scanned during the recording operation, the colouring matter is preferably such that it is dissolved out during the subsequent development or after-treatment of the film.
