Title: Process for imparting a soil-repellant and antistatic finish to  textile materials
IPC: D06M13/295
Filed: 1970-10-21
Abstract: 1325164 Treating textiles FARBWERKE HOECHST AG 15 Oct 1970 [17 Oct 1969] 49064/70 Heading DIP  A process for imparting a soil-repellent finish to textile materials comprises treating the material with an aqueous solution of a mixture of an alkali metal salt of a di-aliphatic C 8-20  ester of orthophosphoric acid, and an alkali metal salt of a di-aliphatic C 8-20  ester of ortho phosphoric acid, and subquently drying the material. The mixture of mono and diesters of orthophosphoric acid can be made by reacting phosphorus pentoxide with a mixture of phosphoric acid mono- and di-aliphatic esters at a molar ratio of less than 1:2, preferably from 1:3 to 1:6, and allowing the mixture of acidic phosphoric esters so obtained to react with an amount of an aliphatic alcohol corresponding to the amount of phosphorus pentoxide used. The orthophosphoric acid esters are generally used in the form of the potassium or lithium salts. The finishing agents are applied to the textiles by for example spraying, padding on one or both sides or by immersing. The finish may be applied either to the final goods or during their manufacture. The mixture of salts of the orthophosphoric acid esters may be applied alone or together with other finishing agents used in aqueous solutions or dispersions, e.g. finishing auxiliaries and binding or fixing agents provided that these are compatible with the anonic phosphoric acid esters. Calculated as a dry film, the amount of finishing agents applied is advantageously from 0.05 to 0.6% by weight, calculated on the weight of the goods. The concentrations of the solutions of the salts of the orthophosphoric acid esters are generally from 3 to 50 g. per litre. The textile materials treated may be made from or contain polyesters, polyamides, polyacrylonitriles, polyolefins or cellulose derivatives. In examples (1) a tufted polyamide pile carpet is sprayed with an aqueous solution of a mixture of potassium salts of mono and di-lauryl orthophosphoric acid esters and dried at 130‹C, (2) a tufted felt carpet having a polyamide/polyester upper fleece, wool/polyamide lower fleece and jute basic fabric is immersed in an aqueous potassium mono/di stearyl orthophosphoric ester salt mixture and dried at 140‹C, (3) a tufted polyacrylonitrile carpet having a glass fibre back is padded with an aqueous solution containing the ester mixture of (1), a self crosslinking butylacrylate / styrene / acrylonitrile / acrylic amide dispersion, and melamine-formaldehyde precondensate and dried at 135‹C, (4) a polyester knitted curtain is padded with an aqueous composition comprising the esters of (1) a styrene/acrylonitrile copolymer and an optical brightener and thermal at 195‹C for 30 seconds and (5) a polyester carylonitrile upholstery fabric is immersed in an aqueous solution of the esters of (1), squeezed and dried at 120‹C.

Abstract: 1,038,149. Lasers. VARIAN ASSOCIATES. Dec. 13, 1963 [Jan. 10, 1963], No. 49464/63. Heading H3B. In a laser the laser active material is pumped by radiation from a fluorescent material incorporated in the laser material. In the embodiment of Fig. 1 laser active material and a phosphor are contained in a hollow cylindrical envelope 1 of a flash or discharge tube which produces optical radiation 2 for exciting the phosphor. The resultant re-emission of the phosphor pumps the active laser material to produce stimulated emission 3 reflected by end mirrors 4, 5. The phosphor may be formed as a coating on the laser material or distributed throughout the medium. In addition the phosphor-laser material may be irradiated from a separate lamp. In Fig. 2 the laser material 1 includes an A.C. electroluminescent material such as zinc and calcium sulphide which generates visible radiation under the influence of A.C. source 7 to pump the laser active material. The laser material 1 may be a semi-conductor or insulator, Fig. 3, electrons and holes being injected into the laser material 1 from N and P type alloy contacts 6, 6<SP>1</SP>. When the injected electrons re-combine with the injected holes radiation is generated which optically pumps the active laser material which may be introduced as impurities into the host semi-conducting material, e.g. rare earth ions in a semiconducting host.

Abstract: 1376105 Clamping mechanism RABONE CHESTERMAN Ltd 19 Jan 1972 [22 Oct 1970] 50254/70 Heading B3B  A quick release clamping mechanism, e.g. a woodworking vice, comprises two clamping elements 10, 12 mounted on a shaft 14 for slidable movement relative to one another and detent means for releasably locking the shaft axially relative to one of the clamping elements. The detent means includes a wedge-shaped member 46 acting on the shaft, the shaft being disengageable from the member by limited rotational movement. In the particular embodiment of Fig. 2 the member 46 and the shaft along one surface portion have co-operating serrations 52, rotation of the shaft bringing a smooth surface portion of the shaft into contact with the wedgeshaped member. Means associated with the shaft, such as a clamping nut 32 imparts relative movement between the damping elements 10, 12 and may incorporate a clutch device 60 whereby unscrewing of the nut effects automatically the limited rotation of the shaft (which is limited by, for example a stop 62 on the shaft movable in a slot 64 in one of the clamping elements 10, 12). The clutch may comprise, as shown in Fig. 2, a spring 66 acting on a washer 68 held on the screwed end of the shaft by a pin 70, or a spring clip (72, Fig. 9, not shown) held between bossed washers (78, 80, Fig. 8, not shown) fast on the end of the shaft, or the clamping nut may be replaced by a nut affording a certain resistance to rotation on the screwed end of the shaft. Alternatively, the shaft need not be rotated by the nut but by other means such as the pin 62 which, if extended through the wall of the associated clamping element may be operated manually. The wedge-shaped member 46 is spring- loaded and held in bore 48 by means of a pin 56 engaging a slot (58, Fig. 5, not shown) in the member. One or more such members may be used and engage corresponding serrated portion of the shaft 14. One or more plain shafts 16 may be employed and are fixed to the movable element 10 and slide in the fixed element 12.

In a process for continuously cracking gaseous and/or vaporizable hydro-carbons, e.g. methane, natural gas, and liquefied low boiling hydrocarbons, with steam and optionally with oxygen, to produce H 2 - and CO-containing gases, the feed is passed through a bed of catalyst located in the annular space between inner and outer concentric tubes, the bed being heated by direct firing of the walls of both the tubes. The source of heat for the inert tube is one or more burners, preferably a single longitudinal burner, at one end of the tube, and several burners normal to the external wall of the outer tube. The tubes may be cylindrical or conical, and may be corrugated on the faces contacting the catalyst, which is preferably nickel and may contain alkali metal oxides. Preferred temperatures are 700‹ to 900‹ C., and pressures up to 50 atmos are mentioned. The object of the invention is to prevent a temperature gradient across the catalyst.

Thus in the Figure, mother liquor from 1, solvent from 2 and inert gas or solvent vapour from 3 are passed through dispersing unit 4 (e.g. a nozzle or reducing valve) to form a suspension of liquid droplets which is destroyed as the suspension passes through Raschig-rings or glassfibre packing 5 and the coalesced liquid droplets settle in tank 6. Dense liquid is drawn off through 8 and light liquid is drawn off through 7. Gas or vapour leaves at 11 and liquid trapped at 9 is recycled via 12.
