The fluorinated compound preferably contains a perfluoro group, has a boiling or decomposition temperature above 120‹ C., contains at least one fluorine atom for each carbon or silicon atom in the molecule and preferably contains at least one chain containing at least 6 carbon atoms. The fluorinated compound may be aliphatic and selected from fluorinated hydrocarbons, alcohols, ethers, aldehydes, ketones, fatty acids and esters thereof, amines and amides and derivatives thereof containing halogens other than fluoride as substituents. Suitable fluorinated aromatic organic compounds are hydrocarbons and halogen, nitro, amino, carbonyl, carboxyl and hydroxy derivatives thereof though preferably fluorinated hydrocarbons are substituted by aliphatic radicals containing a -CF 3  group. Suitable fluorinated heterocyclic compounds include fluorinated cycloamines, cycloethers and substituted pyrroles and pyridines. Fluorinated polymers such as fluorinated polyhydrocarbons, polyethers, polyesters or polyamides may also be used. The fluorinated compound may be applied by contacting the dry coated pigment or an aqueous slurry thereof with the compound in a liquid, molten or dissolved form. Alternatively the fluorinated compound may be emulsified for contact with the aqueous pigment slurry. Preferably successive quantities of the fluorinated organic compound are applied to the pigment.

Title: Improvements in or relating to methods of producing moulded articles of sponge polyurethane
IPC: B29C33/62
Filed: 1961-10-30
Abstract: 940,803. Moulding skinless articles of sponge polyurethane. ROTH FRERES S.A. Oct. 30, 1961 [Nov. 9, 1960], No. 38718/61. Heading B5A. Skinless sponge polyurethane articles are moulded from a mixture of an isocyanate resin and activators, in a mould lined with a film which will adhere to the mould surface and to the skin which forms upon the article during polymerization. The moulding mixture is introduced into the lined mould and the mould heated to partially polymerize the mixture. The partially polymerized article is then removed from the mould during which process the skin formed on the article adheres to the lining film, and is retained within the mould with said lining. Polymerization is then completed outside of the mould. The mould lining film and its adherent skin are easily removed for speedy re-use of the mould. Such a film may be obtained by brushing or spraying a fluent substance, e.g. a solution of rubber latex or a pulp suspension on to the mould surfaces and allowing it to dry. The film may be preformed and applied to the mould surfaces by a vacuum technique.

Abstract: <PICT:0361173/III/1> Hard asphalt is made by distilling asphalt - containing materials such as crude petroleum or residues thereof, with a heat carrier which is liquid, and is free from volatile constituents at the distillation temperature, for example asphalt from a previous distillation.  Petroleum residue is fed by a pump 2 through a pipe 3 in which it is mixed with asphalt fed through a tube 11. The mixture passes through a heater 4 and a pipe 5 to a separator 6 in which the volatile constituents are removed through a pipe 7. The asphaltic residue, which has a melting-point of about 140 DEG C., may be removed through a tube 8, or may be used as a heat carrier and recycled through a tube 9, pump 10, and tube 11.

Abstract: 1357528 Gripper axminster looms QUAYLE CARPETS Ltd 3 Aug 1971 [15 Aug 1970] 39424/70 Headings D1E and D1K In a gripper Axminster loom, rows of short and long pile tufts are selectively obtained by moving a carriage 12 mounting carriers 11 away from the grippers 14 after they have gripped the yarn ends by either a short or a longer distance. When a long tuft is desired the carriage is moved back by plunger rod 18 which is driven from a cam shaft of the loom, until it comes-into contact with an abutment 44 (Fig. 3, not shown) and when a short tuft is desired, a Jacquard controlled wire 50 lowers a plate 47 slidably mounted on carriage 12, which comes into contact with abutment 43 before the carriage does, (Fig. 2, not shown). A spring biassed lost-motion device 27 in the plunger rod 18 then takes the driving force for the carriage. By this means J-shaped tufts are inserted into the fabric, and weft-wise raised or depressed strips may be produced in the pile. Some of the carriers may have empty pile yarn apertures which may be brought by the Jacquard into register with the gripper on certain picks so that a group of high tufts may be formed in a background of low tufts.

Title: Semiconductor devices and methods of fabricating them
IPC: H01L21/331
Filed: 1964-09-28
Abstract: 1,072,778. Transistors. RADIO CORPORATION OF AMERICA. Sept. 28, 1964 [Oct. 24. 1963], No. 39456/64. Heading H1K. A transistor in which the base includes a plurality of conductive paths constituted by semi-conductor material of the same conductivity type but lower resistivity than the remainder of the base, and the emitter consists of a plurality of discrete but interconnected emitter regions, is made by a process of successive diffusions of impurity into the surface of a semi-conductor body. Fig. 1l shows a portion of such a transistor after the final diffusion stage of the process. On an N- type silicon substrate 10 a high resistivity N-type collector layer 14 has been formed either by epitaxial deposition or by diffusion of impurity into all surfaces of the substrate and removal, by cutting and/or etching, of the diffused layer from all but one surface. Into the region 14 boron has next been diffused, through an etched oxide mask, to form a P-type base zone 16 which covers all but the periphery (not shown) of the surface of the layer 14. A further oxide masked diffusion of boron into the base zone 16 produces the P+ zones 19 to provide the conductive paths in the base layer; these zones extend partly into the collector layer. It is possible to reverse the order of diffusion of zones 16 and 19, first forming strip-like P-type zones 19 in the collector surface and subsequently diffusing further boron into the major part of the collector surface to provide the P-type base zone 16 and thus at the same time increasing the conductivity of the already present zones 19. A subsequent diffusion of phosphorus into spaced portions of the base 16 between the zones 19 provides the plurality of N-type emitter zones 21. After this diffusion the etched oxide mask 25 is formed in which mask there is an aperture 35 over part of the surface of each emitter zone 21 and strip-like apertures 38 over at least some of the conductive paths 19 in the base zone. An aluminium or gold layer is then vapour deposited over the oxide and partly etched away to provide two inter digited electrode layers 42, 44 (Fig. 6, not shown) of which one interconnects the emitter zones and the other contacts at least some of the zones 19 in the base, the two electrodes being insulated from each other by remaining portions of the oxide layer 35. The completed device may be encapsulated. In the above described process N-type zones may be P-type and vice versa; silicon may be replaced by germanium or an alloy such as germanium-silicon, gallium arsenide or indium phosphide; and the silicon oxide coatings may be replaced by coatings of magnesium oxide or fluoride. The process may be used to form a hundred or more transistors simultaneously in one semi-conductor wafer which is subsequently divided into separate transistors.

Dec. 20, 1957 [Dec. 21, 1956], No. 39701/57. Class 69 (2). In an hydraulic system of a machine having tools actuated by cams through dual-line telemotors, each telemotor line 13 . . . 16, is connected to one end of a cylinder 11 having a compensating piston 12, the other end of the cylinder communicating with a line 17, 20 common to all the cylinders and pressurized by a spring- loaded piston 22, the loading of which is adjustable. If the pressure in a telemotor line falls, the associated piston 12 is moved to the position shown in Fig. 2 in which liquid is supplied to the telemotor line from a common supply line 19 via a groove 23 and a passage 35 in the piston. If the pressure in a line rises, the associated piston 12 is depressed until groove 23 registers with a common exhaust line 18. If a sudden rise in pressure occurs, as when a tool is obstructed or breaks, the associated piston 12 is moved to its lowermost position in which a switch 27 . . . 30 is actuated to stop the machine and operate an indicating device 31 ... 34. Replenishing liquid is supplied through line 19 by a spring-loaded piston 38. If pistons 22, 38 reach the end of their stroke they operate switches 25, 41 to stop the machine and operate indicators 26, 42. Fresh liquid can be supplied to line 19 through a feed nipple 43.
