Title: Apparatus and method for producing bulked slub yarn
IPC: D02G1/16
Filed: 1960-06-08
Abstract: 951,592. Spinning fancy yarns; thread guides. EASTMAN KODAK CO. June 8,1960 [June 8, 1959], No. 20156/60. Headings D1D, D1F and D1W. In the production from two (or more) multifilament yarn ends of a composite yarn containing randomly spaced, sharp, bulky slubs, one end is passed through a guide moving in timed relation to a second guide (so as alternately to store and release the ends), another end is passed through the second guide whereby each end is alternately fed at a faster and slower rate than the input rate, all the ends are then passed through a bulking gas jet wherein they are subjected to a smooth air flow (which is free from transverse components and sudden erratic changes in the direction of flow) so that the slubs are formed, and the withdrawn composite yarn is taken up in package form e.g. on a twister which inserts three turns per inch of twist. In the final yarn, one end at certain intervals constitutes a core yarn and at other intervals the other end forms the core: excess yarn in the slub consists of a tangled mass of continuous filaments and the core yarn at the slub contains few, if any, filament loops. The component yarns may be identical or differ as regards finish, colour and/or material e.g. cellulose acetate, polyacrylonitrile, polyamide, polyester, vinyl resins. In the apparatus shown in Figs. 1 and 2, yarns 1, 2, withdrawn from packages 3, 4, through guides 5, 6, and tension guides 7, are advanced by a constant speed roller 8 and pressure roller 9 through a stationary guide 10, separately through guides 11 and 12 mounted on an adjustably reciprocating slubber bar 13 (shown in successive positions A, B, C) optionally through a collecting guide 26, into a jet 14, and slubbed yarn 15 is wound by spindle 16. More than one end may be passed through each moving guide. In the driving apparatus shown in Fig. 3, rotation of a crank arm 17 on a shaft 18, through connecting rod 27, reciprocates bar 13. A pin 21 integral with shaft 18, is engaged by trigger pins 24 randomly spaced along a roller chain 23 (which drives a continuously rotating idler sprocket 22) to compel rotation of shaft 18 through increments of one half a revolution under control of a brake 25 acting on a drum 19. The speed of chain 23, the throw of arm 17, the length of rod 27 and/or the spacing of the guides and jet may be adjustably varied to regulate the dimensions, form and frequency of slubs. The bar 13 may be driven by hydraulic or air cylinder, one revolution clutch and crank arm or solenoid (not shown). Specification 818, 157 is referred to.

Title: Improvements in terminal boxes
IPC: H02B13/025
Filed: 1963-05-21
Abstract: 1,097,051. Junction boxes. LAURENCE SCOTT & ELECTROMOTORS Ltd., and K. K. SCHWARZJuly 15, 1964 [May 21, 1963], No. 20178/63. Heading H2E. A terminal box made of electrically conducting material for use in supplying three-phase alternating current to electrical equipment, is divided into three compartments 6, each having an inlet aperture 14 for the passage of an insulated conductor 11, carrying current in only one of the three phases, and a second aperture 15 for the passage of an outlet lead 13 to the equipment. The box and its contents are arranged so that if an electric fault occurs within the compartment, arcing occurs between the fault and the conductive walls of the box, this distance being made as small as possible so that the pressure produced by arcing, which is proportional to arc length, is kept to a minimum, and is withstood by a compartment if a fault affecting only a single phase occurs. The current flows from the fault to the compartment, and then through an impedance back to the neutral line and the cable. This current is limited to a low value by the value of the impedance in the neutral line. Accordingly, if a fault develops in a single phase, the compartment can withstand the pressure while the fault current causes external means, e.g. circuit-breakers, to interrupt the current supply. If faults develop simultaneously in two or more phases the impedance earthing cannot limit the maximum fault current and a high pressure is set up before the circuit-breakers can operate, and therefore a vent covered by a diaphragm is provided in each compartment. A steel strip 18 is welded along each side of each compartment about half way up to limit the maximum arc length to approximately half the height of the compartment. A cable consisting of three individually insulated conductors may also be used, in which case a sealing box is secured below the terminal box, the sealing box being filled with compound or oil. The sealing box is also divided into three compartments. In this embodiment a multiphase fault which occurs under the compound or oil can be contained provided the compound or oil can expand upwardly into the sealing box.

Abstract: 1,187,861. Coating with metals. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 4, 1967 [May 7, 1966], No.20715/67. Heading C7F. [Also in Division G2] A metal nobler than cadmium and less noble than mercury, e.g. Co, Pb, Sn, Cu, Ni, Tl, In, Mo, Ge, is deposited selectively on an image of mercury and/or silver nuclei from an aqueous solution containing reducing metal ions, e.g. Fe, V, Ti, Cr or Eu, which in the solution have a reduction potential less than 780mV but more than -43OmV. The process is carried out in a non- oxidizing atmosphere. In an example, a saponified cellulose triacetate foil is sensitized by impregnating in a solution containing per litre 0À4 mol. of the sodium salt of p-methoxybenzenediazosulphonic acid, 0À1 mol. of Cd lactate, 0À1 mol. of Ca lactate, and 0À1 mol. of lactic acid, exposed behind a line negative to a high pressure mercury vapour lamp, and then treated with an aqueous solution containing, per litre; 0À005 mol. of mercurous nitrate, 0À01 mol. of silver nitrate, and 0À01 mol. of nitric acid. After washing, the foil is treated with calcium nitrate to replace silver and mercurous ions absorbed by the cellulose, with calcium ions. After again washing, the latent silver amalgam image is intensified by contacting, in a nitrogen atmosphere, with a solution comprising (parts by volume) 2 of an aqueous solution of (50%by weight) tin hexafluoride, 0À8 of an aqueous solution of 0À5% by weight of each of a cationic and a non-ionic surface active agent, 5À2 of oxygen free water, and 2 of a solution prepared by dissolving vanadyl sulphate in water and then adding sulphuric acid. The resulting tin pattern can be brightened by rubbing.

Abstract: The mixtures of the acids of the formula (I) or (Ia) - the symbols are defined in Claim 1 - contain the individual acids, classified according to the numerical value of n or m and n', in the following amounts: 1)   n = 1 : 10 to 40%      n = 2 : 15 to 35%      n = 3 : 30 to 10% n = 4 : 25 to 10% and      n = 5 : 20 to  5% and 2)   m = 1 and n' = 1 : 10 to 15%      m = 1 and n' = 2 : 20 to 30%      m = 1 and n' = 3 : 15 to 20%      m = 2 and n' = 2 : 25 to 30% and      m = 2 and n' = 3 : 15%   The acid mixtures are used in the form of their heavy metal salts as siccatives; they have the advantage that the theoretical metal content is achieved. They can also be used for separating metal cations from solutions. These mixtures are obtained by free radical teleomerisation of acids (R2)2CHCOOH or R1CH2COOH (R1 = C1-C4-alkyl, R2 = CH3 or n-butyl) with gamma -olefins CH3CH=CH2 or C2H5CH=CH2 in a molar ratio of carboxylic acid : olefin of from 1 : 0.3 to 1 : 1.5 at from 150 to 180 DEG C in the presence of from 1 to 5% of peroxide initiator.
