Patent GB-321239-A (GB)
Abstract: 321,239. Johnson, J. Y., (I. G Farbenindustrie Akt.-Ges.). Aug. 7, 1928. Emulsions, making; disinfectants; vermin-destroying compositions.-Emulsifying agents for tars, oils, fats, resins, cresols, higher alcohols, bitumens or hydrocarbons and their derivatives in admixture if desired with substances such as sulphur, phosphorus, arsenic or selenium, are prepared by treating products, obtained by oxidation of animal, vegetable or mineral waxes with gaseous oxidizing agents, with 20-40 per cent of their weight of chlorine at a temperature below 100‹ C. and subsequently treating the chlorination products with basic reagents. The substances preferably treated are the acid constituents of the oxidation products. Both the oxidation products themselves and their acid constituents may be treated in conjunction with fatty or resin acids. The emulsions when prepared may be employed in road construction, or in disinfection or the destruction of vermin or pests. Examples of the invention are as follow : (1) 100 parts of the products, obtained by oxidizing soft paraffin wax and subsequently isolating the acid constituents by converting into salts, extraction with organic solvents and treatment with acids, are dissolved in carbon tetrachloride and treated at about 70‹ C. with 20-3C parts of chlorine introduced through nozzles, fritted glass &c. The pale yellow product obtained after distilling off the solvent is stirred into 5000 parts of molten Mexican asphalt and then mixed with dilute caustic soda solution to form a stable emulsion. (2) 100 parts of dark-coloured products, pressed or. sweated out of oxidized paraffin wax, are dissolved in 200 parts of carbon tetrachloride and chlorinated as in (1); after washing and removing the solvent the product is mixed with 20 times its weight of resinous lubricating oil, neutralized with 10 per cent ammonia and diluted with water. (3) An emulsifying agent is obtained by chlorinating as above, but at 80‹ C., 100 parts of an air-oxidation produced of montan wax, distilling off the solvent and adding 150 parts of 20 per cent caustic soda solution. (4) 100 parts of an air-oxidation product of montan wax and 50 parts of wool-fat acids are dissolved in glacial acetic acid and treated with 55 parts of finely divided chlorine; the acetic acid is then distilled off and the product mixed with 5000 parts of brown coal tar, 500 parts of finely divided sulphur, and dilute caustic soda solution to form a stable emulsion.

Title: Image display screens
IPC: H01J29/32
Filed: 1958-10-08
Abstract: 899,251. Luminescent screens. SYLVANIA ELECTRIC PRODUCTS Inc. Oct. 8, 1958 [Oct. 8, 1957], No. 32166/58. Class 39(1). A multi-colour luminescent screen has a poisoning agent, such as iron, cobalt or nickel, diffused into the surface layers of at least the phosphor particles of one colour nearest the electron gun, to reduce the luminescent efficiency of this phosphor, so that low velocity secondary electrons, or electrons deflected by the shadow mask, do not excite the phosphor and cause colour de-saturation. The screen may be prepared by photographic printing techniques, the poisoning agent being contained in the light-hardenable substance associated with the relevant phosphor or being applied to the individual phosphor crystals prior to their application to the screen. Alternatively, the screen may be washed with a solution of the poisoning agent, e.g. 0.1 to 0.00005% by weight aqueous solution of ferric nitrate, after only the one or more phosphors whose light-emitting efficiency is to be reduced, e.g. the green and blue phosphors, have been applied to the panel. The poisoning agent may be in the form of a salt solution. As a final step in the screen-forming process, the screen may be baked above 400C. to remove volatile impurities and aid in the diffusion of the poisoning agent into the surface of the phosphor or particles. Suitable known luminescent materials, light-hardenable substances and solvents therefor, are specified. In particular, the luminescent material may comprise sulphides, oxides, tungstates, aluminates, borates, selenides, phosphates or silicates of one or more of zinc, cadmium, beryllium, magnesium, manganese, calcium and strontium, activated by silver, copper or manganese.

Title: Means for exerting longitudinal thrust on a column, caisson or the like
IPC: E02B17/08
Filed: 1954-11-09
Abstract: 754,318. Driving and withdrawn piles &c. UNITED STATES STEEL CORPORATION. Nov. 9, 1954 [Sept. 10, 1954], No. 32448/54. Class 68(2) In apparatus for driving or withdrawing columns or caissons, more particularly in establishing or removing a barge-platform for off-shore oil-well drilling, the lower gripper, mounted on the barge, comprises a casing with wedging-slips which grip the column, and the upper gripper comprises contractible friction gripper means, poweroperated thrust means on the barge being connected with the upper gripper to produce the required longitudinal movements. The gripper casing 19 is secured to a base plate 16 which is clamped to the deck 11 of the barge 10 by a plate 17, the caisson or column 15 being passed through the grippers and through a well 14 which extends from the deck to the bottom of the barge. The casing 19 has oppositely tapered inner surfaces 21, 22 which co-act with rings of segmental slips 24, 44 which are urged into jamming positions by springs 25. Compressible material is arranged between individual slips 24, 44. The upper slips 44 are supported, when inoperative, upon a ring 45 which is carried by the piston rods 42 of a number of peripherally spaced fluid-pressure cylinders 40. When the rods 42 are lowered, the upper springs 25 bring the slips 44 into operation, and the ring 45 pushes the lower slips downwards out of operation. The cylinders 40 thus permit the grippers 19, 25, 44 to be set for raising or lowering the caisson 15 relatively to the barge 10. The actual relative movement is effected by double-acting fluid-pressure cylinders 34 which are anchored at 35 to the plates 17, the piston rods 36 being connected to a friction gripper assembly 30. This consists of a rubber ring 32 fitted with segmental shoes 33 having serrated gripping faces. The ring 32 is accommodated in a metal body in such a manner that fluidpressure admitted at 31a contracts the ring and segments upon the caisson 15 which is gripped firmly. By contracting and releasing the ring 32 and actuating the cylinders 34, the gripper 30 takes a fresh gripping position on the caisson. either higher or lower, and the slips 24 or 44 are actuated to. hold the caisson between fresh positionings of the gripper 30, by actuation of the cylinders 40. In a modification, Fig. 7, the slips 60, 61 are thrust selectively against the caisson 15 by a wedging-ring 53 slidable within the casing 50 and actuated by a number of screws 54 driven simultaneously by a chain 57a. Aligned slips 60, 61 are connected by links 63. When the barge is raised to the desired height on the caissons, it may be supported by semi-permanent means, eg., bolted brackets, to relieve the slips.

Abstract: 846,705. Two-way transmissions. PINTSCHELECTRO G.m.b.H. Oct. 26, 1956, No. 32719/56. Class 40 (4). [Also in Group XL (b)] A hybrid circuit comprising three pairs of terminals and incorporating a differential transformer 1 also includes a resistive quadripole designed so that the impedance at all three pairs of terminals is identical so that the circuit may be used to connect a two-wire line to a four-wire line. The impedance z at a first pair of terminals i, k connected to the secondary of transformer 1, is half that 2z at the transformer terminals e, f. Said transformer terminals are connected to a matching resistive quadripole wl, w2 so selected that the impedance at the twowire terminals g, h, is also z. As the impedance at the terminals c, d, taken from the centre tap of the transformer, is z, the required conditions are satisfied. The quadripole in addition provides attenuation at terminals g, h to limit the transmitted signals. The network N balances the impedance 2z. In a modification, Fig. 5 (not shown) the transformer and quadripole are symmetrically designed with respect to earth and a resistance divider w3, w4, may be employed to produce a balanced network.

Filed: 1961-09-19
Abstract: 1,029,838. Modified viscose rayon. COURTAULDS Ltd. Sept. 18, 1962 [Sept. 19, 1961], No. 33449/61. Heading B5B. Modified viscose rayon is produced by wet spinning into an acidic coagulating and regenerating bath a viscose containing 10 to 40% of a protein such as casein based on the weight of the cellulose, and 10 to 40% of urea based on the weight of the protein, stretching the filaments and completing the regeneration of the cellulose component. In order to reduce the tendency for the polypeptide to be leached from the filaments in wet processing, the filaments are preferably impregnated with a cross-linking agent for one or more of the components of the filaments and the impregnated filaments are then preferably submitted to conditions causing the agent to react with one or more of the components. The cross-linking agent may be formaldehyde, an alkali metal cyanate or a zirconyl salt such as sodium zirconyl silicate. The viscose may be formed by mixing a protein, urea and alkali cellulose and xanthating the cellulose in known manner, or the protein and urea can be added to the ingredients of the viscose at any subsequent stage of the making of the viscose, including addition of protein and urea to the preformed viscose. As proteins are subject to degradation by caustic alkalis and viscose is alkaline, the protein and urea are preferably added to the viscose immediately before it is de-aerated on its way to an ageing tank or a spinning machine. In an example, 100 parts of a viscose containing 7À6% of cellulose and 6À2% of caustic soda are mixed with 1À52 parts of casein and 0À31 part urea, the mixture is agitated until the casein and urea have dissolved and is then filtered and deaerated. The solution is spun into a coagulating and regenerating bath containing 10% sulphuric acid, 20% sodium sulphate and 1À1% zinc sulphate. The filaments are taken from the bath, stretched by 60% of their original length before they are completely regenerated with hot dilute acid, washed and dried. The modified regenerated cellulose filaments of the invention are dyeable with acid dyes and have higher wet and dry strengths than prior art modified regenerated cellulose filaments.
