Filed: 1955-05-20
Abstract: In the copolymerization of an alkene having 3 to 5 carbon atoms and a polymerizable compound containing one olefinic linkage and an aromatic nucleus in the presence of a lower alkyl halide diluent and a Friedel Crafts catalyst at a temperature below 0 DEG  C., the two reactants are mixed in liquid phase in approximately the desired proportions, the resulting feed mixture is adjusted to the specific gravity of a mixture of monomers in the desired proportions at the same temperature, the mixture is diluted, cooled and the catalyst added to effect polymerization.  In a modification the specific gravity of the diluent-reactant mixture may also be adjusted. Specified monomers are isobutylene, methyl-2-butene-1 styrene, p-methyl, p-ethyl and p-chloro-styrenes, vinyl naphthalene, indene and dihydronaphthalene.  Suitable solvents are methyl, ethyl or propyl chloride or the low boiling fluorides, and Friedel Crafts catalysts such as aluminium chloride and boron fluoride are described.  In an example, styrene and isobutylene under pressure are mixed in approximately the desired proportions, adjusted accurately by the specific gravities at 97.5 DEG  F., and the methyl chloride diluent added.  The proportions are again adjusted at 97.5 DEG  F. (i.e. the temperature at which methyl chloride and styrene have the same specific gravity) to the final proportions required, the blend cooled to - 100 DEG F. to - 150 DEG F. and polymerized in a continuous batch process.  The copolymer may be recovered by passing into hot water to form a slurry and flashing off the solvent.

Title: Improvements relating to the crimping of artificial filaments by the compression process
IPC: D02G1/12
Filed: 1960-04-28
Abstract: 888,786. Crimping fibres. BARMER MASCHINENFABRIK A.G. April 28, 1960 [April 30, 1959], No. 14979/60. Class 120(3) In apparatus for compressively crimping artificial filaments by supplying the filament to the crimping chamber at constant speed and regulating the withdrawal of crimped filaments therefrom in dependence on the chamber filling or vice versa, supply or withdrawal is effected alternately at one and then the other of two specific and slightly different speeds which span the necessary mean winding speed. A changeover device, actuated by fluctuations in the volume of filamentary material in the chamber, initiates the speed alternation by mechanical, electrical or electromechanical, or hydraulic adjustment means, e.g. a friction disc or eddy current coupling or a regulating circuit, which permits or causes a motor shaft to rotate at one of two slightly different speeds or changes the motor speed, e.g. by connecting the motor to two different voltages or frequencies. As shown, a filament 1 is fed by constant speed rollers 2 and 3 into a chamber 5 wherein it is heated and then cooled as it is compressed into superposed convolutions to form a plug 7 against the resistance of an assembly of balls 6 through which the crimped material is withdrawn, past a feeler pin 15, and wound into a package 27 by a roller 17. Variation in the level of plug 7 causes movement of a scanning and setting member 8 (through an arm 9 adjustably positioned by a displaceable carrier 10) which, at a predetermined position, actuates and releases a micro-switch 13 to energize and de-energize the coil 32 of a magnetic change-over switch 31 which thereby connects a three-phase supply R<SP>1</SP>S<SP>1</SP>T<SP>1</SP> or RST at a frequency of 31 or 28 cycles per second to a motor 22 which thus drives roller 17 at corrective speed. A feeler plate 16 of the member 8 may be hollow and/or drilled for the passage of crimped filament therethrough. In another modification, the switch 13 is mounted directly on the rim of the chamber and the pushbutton therefor is formed as a feeler pin. The supply frequencies may be predetermined by adjustment of gearing between component units of a motor-generator set and multiple crimping units may operate from common, multiphase, alternate supplies, Fig. 3 (not shown).

Title: Sewing machine attachment for overcasting and serging
IPC: D05B21/00
Filed: 1951-06-25
Abstract: 698,982. Sewing-machines. JACOBSON, P. June 25, 1951 [June 29, 1950], No. 15031/51. Class 112. An attachment for reciprocating the work laterally for overedge stitching comprises rotary work grippers, provided with teeth and rubber bands, arranged to hold the work flat, the grippers being rotated by contact with the work as it is fed by the usual dog and being reciprocated laterally by connections from the needlebar of the machine. Means are provided for lifting the usual presser-foot during lateral feed of the work, which takes place while the needle is out of the work and before or after the feeddog is in engagement with it. In the form shown a base-plate 83, fixed to the bed of the machine and formed with an aperture through which the feed-dog engages the work passing over it, carries a housing 22 in which are mounted a shaft 36, rotated intermittently through a ratchet wheel 45 by a lever 57 connected to the needle-bar, a sliding bar 62 with an angularlyadjustable cross-bar 63 supporting L-shaped arms 59, and a lever 34 with an adjustable endpiece 31 for engaging the usual presser-lifting lever of the machine. The arms 59 are pressed downwards by springs 65, which are adjusted by rotating the cross-bar 63 by means of a fingerlever 66 and securing it by a set-screw 61, and carry the spindles of two work-engaging wheels 72, 72a, which are interconnected by three idler gears supported by a bridge 81 pivoted on the front spindle 58 and resting on the rear spindle 58, being secured by a latch 76; the middle idler gear carries a work-engaging wheel 73 closer to the bridge than the wheels 72, 72a so that it can act when the end of the work has passed the wheel 72. The bridge is vertically adjustable on the front spindle by a screw 78 to lift the wheel 73 clear of the work, and the whole wheel assembly may be lifted about the cross-bar 63 by a finger-piece 77. Each wheel has a rubber band 70 to engage the extreme edge of the work and teeth to engage the adjacent portion, the teeth on the wheels 72 and 73 being formed so that these wheels are rotated by the moving work and those on the other wheel 72a being arranged to feed the work; the latter wheel is slightly larger than the former so that the work is kept taut under the needle. The bar 62 is reciprocated, for the lateral feed of the work, by a cam on the shaft 36, and the lever 34 is lifted by a second cam. The lever 57 may be modified to suit different machines, and the ratchet drive may be reversed; the housing 22 may be provided with alternative slits 21 for the presser-lifting lever 34 so that it may be placed according to the direction of rotation of the shaft 36.

Title: Improvements in patterned hosiery and method and apparatus for making the same
IPC: D04B9/26
Filed: 1957-05-13
Abstract: 855,060. Knitting. TEXTILE MACHINE WORKS. May 13, 1957 [May 15, 1956; July 17, 1956 (3); July 18, 1956], No. 15141/57. Class 74 (2). Intersia fabric, for example, a leg of a sock, is knitted on a four feeder circular machine by reciprocatory knitting and has overplaid yarns incorporated in it as it is produced. In the case of a sock, diamond-shaped areas are knitted simultaneously by reciprocation at each side of the sock followed by the simultaneous reciprocatory knitting of diamond-shaped areas at the front and rear. The shaping of the areas is achieved by needle selection and the various areas are joined together by sutures. In knitting two opposed areas on the machine a body yarn 26 is fed to one group of needles 24 to 25 and knitted at a No. 1 feed, Fig. 5, followed by the feeding of an overplaid yarn d to selected needles 30 of the group and the knitting of it by these selected needles at a No. 2 feed the other needles remaining inoperative. Simultaneously, an opposed group of needles 27 to 28 knits a body yarn 29 at a No. 3 feed followed by the selected needles 33 knitting an overplaid yarn g at a No. 4 feed. On reverse movement of the needles they again take and knit the respective body yarns except that the selected needles 30 and 33 and further selected needles 32 and 31 remain at low level and the body yarn is allowed to float over their wales. Continuing their movement the further selected needles 32 and 31 take and knit further overplaid yarns h and c at the No. 4 and No. 2 feeds. During the next stroke of the machine all of the selected needles are held low and the remaining needles knit the body yarn so that further floats are produced across the wales of the selected needles. Prior to the needles approaching the No. 2 and No. 4 feeds a further selection is made of the needles and the sequence of operations is repeated. These operations result in a fabric as illustrated in Fig. 3 being produced. Alternatively all of the needles of a group may knit the body yarns in each course followed by the selected needles taking and knitting the overplaid yarns. After completing one pair of opposed diamondshaped areas the feeds are reversed so that No. 2 and No. 4 feeds supply the body yarns and No. 1 and No. 3 feeds supply the overplaid yarns for completion of the other pair of opposed areas. Where the first and last portions of each diamond-shaped area do not include an overplaid yarn the first portions of one pair of opposed areas may be knitted simultaneously with the last portions of the other pair of opposed areas so that four areas of fabric are produced simultaneously by reciprocatorily knitting a body yarn at each of the four feeds. The overplaid yarns knitted in one diamond-shaped area are floated vertically over the intervening areas until they are again incorporated in the diamond-shaped area immediately below the one above.
