Title: Synthetic rubber latices
IPC: C08F236/04
Filed: 1968-03-18
Abstract: 1,220,384. Copolymer latex. FARBENFABRIKEN BAYER A.G. 18 March, 1968 [20 March, 1967; 25 March, 1967], No. 12880/68. Heading C3P. A copolymer latex contains in emulsified form a copolymer of 40 to 98 parts by weight of a conjugated diene, 0À1 to 50 parts by weight of at least one olefinically unsaturated comonomer, 0À1 to 10 parts of an olefinically unsaturated carboxylic acid having 3 to 6 carbon atoms and 0À1 to 10 parts by weight of a carboxylic acid or a mixture thereof, having 10 to 30 carbon atoms. The diene may be butadiene, isoprene or chloroprene. The olefinically unsaturated monomer may be acrylonitrile, methacryonitrile, ethyl acrylate, methyl methacrylate, vinyl acetate, vinyl chloride, styrene or α-methylstyrene. The olefinically unsaturated acid may be acrylic or methacrylic acid. The carboxylic acid may be a mixture of C 12  to C 18  aliphatic carboxylic acids. The latex may be prepared by emulsifying the components in an aqueous medium and polymerizing the mixture in the presence of a free radical forming catalyst at 5‹ to 100‹ C. at a pH of below 7. In the examples butadiene, a solution in styrene, (meth)acrylonitrile or methylene glutarodinitrile of a long-chain fatty acid mixture of acids containing 12 to 18 carbon atoms, and methacrylic acid are emulsified in an aqueous medium using at least one anionic emulsifier. The emulsion is polymerized with a redox catalyst system and the polymerization terminated using an aqueous solution of sodium dithionite and the sodium salt of ethylene diamine tetra-acetic acid. The latex is stabilized using styrenized xylenol and diphenylamine, and the latex is then creamed followed by the addition of vulcanizing agents, pigments and fillers. The latex mixture formed as above is used to form shaped articles by the dip-tank process.

Title: Improvements relating to p-n junction semi-conductor devices
Inventor: CUMMING HARRY WYNDHAM LISTER
IPC: H01L21/304
Filed: 1958-04-24
Abstract: 881,499. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 25, 1959 [April 24, 1958], No. 13063/58. Class 37. A multiple junction semi-conductor device is made by locally melting part of a semi-conductor crystal of one conductivity type containing an acceptor and a donor impurity, the dominant one of which has a much lower segregation coefficient which, however, increases more rapidly with increase of growth rate than that of the other impurity. On recrystallization the impurity of higher segregation coefficient predominates in the initially recrystallizing material, but as the growth rate increases with the decreasing temperature gradient across the solid-liquid interface resulting from cooling of the crystal, the other impurity again predominates to give rise to a second PN junction. After recrystallization is completed the outermost zone of said one conductivity type is cut or ground to form a flat surface and an activator pellet characteristic of the opposite conductivity type fused to it to form a further PN junction. Methods of grinding and lapping a number of bodies simultaneously are described. In the embodiment the starting crystal is of N type germanium doped with gallium and antimony and the local heating is effected in inert gas such as nitrogen by an oxyhydrogen torch. The progressive increase in growth rate is controlled by varying the rate at which the torch is withdrawn or by separate cooling means. The final junction is formed by fusing indium to the outer N zone in a two-stage heating process. Nickel leads are finally simultaneously tin soldered to the main body and fused to the indium pellet respectively to form a twoterminal device exhibiting the forward characteristic shown in Fig. 6. Specifications 727,900, 752,457 and 781,795 are referred to.

IPC: D04H17/00
Filed: 1918-08-15
Abstract: 129,496. British Thomson - Houston Co., (General Electric Co.). Aug. 15, 1918. Winding-machines; stop-motions.-A machine for making gear-wheel blanks from textile fibres as described in Specification 113,103, [Class 80 (i), Gearing, Belt &c.], comprises means for winding cotton or other slivers helically on a flat mandrel to form a thin strip, a nd for winding this strip edgeways on a drum. Two or more slivers 6 are contained in cans 5 mounted on a rotary table, and are drawn through helical spring guides 64 and through tubes 65 in a hollow rotary shaft 15 by a winding-head 16, by which, after passing over pulleys 71, 72, the slivers are wound round a flat stationary mandrel 70 sup. ported by a rigid bar 68 extending through the shaft 15. A core 75 consisting preferably of two wires, is drawn from two spools 76 through guide tubes 81, 82 along the bar 68 to the mandrel, and the ends are secured to a drum 37 on which the flat coil formed on the mandrel 70 is wound edgeways. The coil is pushed off the mandrel and delivered to the drum by a series of gripping- fingers 83, Figs. 1 and 9, pressed together by springs 88 fastened to the upper parts 87. The fingers are all mounted in a carriage which is reciprocated by a lever 92 provided with an adjustable pivot. operated by a cam 33. During the movement away from the drum the fingers are separated to release the grip on the coil by cams 89 operated by a cam on the shaft 31. The coil is received by the overlapping ends of a presser 61 which encircles the drum 37, being adjustably mounted on a rod 60. The coil is thus consolidated on the drum on which it is bound by its wire core. The drum 37 is driven by worm gearing 45 and is counterweighted so that it descends on a guide 49, Fig. 13, as the coil is wound. The guide 49 is secured by clamps 47 to a rotary table 42 secured in position by an adjustable stop 48. On withdrawing the slide 41 the drum 37 can be removed from the machine. By loosening the clamps the drum can be rotated independently of the table 42. When two or more blanks are to be formed in one winding operation, a sheet of paper or other separator is inserted at the proper place between the coils of the helix to prevent the adhesion of adjacent coils, the machine being stopped automatically when a helix of the desired length has been wound. The machine is driven by an electric motor 21 controlled by a switch 110, Figs. 1 and 23, actuated by a pivoted spring- pressed latch 114, which is moved to stop the machine by a block 120 on a toothed wheel 119 rotated by a pawl 118. A projection 116 on the table 42 engages an arm 117 at each revolution and advances the wheel 119 one step. A movable stop 123 is inserted in holes 122 corresponding to revolutions of the drum, to determine the number of coils to be made before the switch is actuated, the wheel 119 being turned back by hand after each operation until the block 120 engages the stop 123. The switch is re-set by a push 115.
