Title: Improvements in and relating to methods of detecting radiation
IPC: H01L31/00
Filed: 1965-02-09
Abstract: 1,087,274. Photo-cells. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 9, 1965 [Feb. 12, 1964], No. 5534/65. Heading H1K. A radiation detector consists of a photosensitive semi-conductor body with an intermediate energy level in the forbidden gap through which electrons can be raised from the valence to the conduction band in two transitions, associated with a source of photons capable of causing one of the transitions but of insufficient energy to cause direct transitions. Radiation to be detected has to include photons able to cause the other transition. In a typical arrangement the photon source and photosensitive body are included in a common P-type gallium phosphide body 1 (Fig. 4) by alloying tin pellets 6, 23 to it to form PN junctions. An ohmic contact is formed simultaneously by a zinc doped gold pellet 8 alloyed to the body in 1 second at 400-700‹ C. Alternatively the junction 25 providing the photons may be in a separate body. In this case the junction may be formed in the same way or by alloying zincdoped indium and tin to N-type gallium arsenide or indium phosphide to form the PN junction and ohmic contact respectively, though the junction may also be formed by zinc diffusion. In either case, the body may be formed on the gallium phosphide body by epitaxial deposition. Another possibility is to form photon source and detector junction on opposed faces of a base body by diffusion or epitaxial deposition. The source, which may also be a tungsten lamp with a monochromatic interference filter, and the photosensitive body, which need not include a PN junction, are preferably mounted in a common housing.

Abstract: Compositions comprise plasticised vinyl chloride polymers or copolymers, butadiene-acrylonitrile copolymers and electrically conductive carbon black.  Specified carbon blacks are lamp black, acetylene black and furnace blacks such as Philblack A and Philblack O.  Specified plasticisers are tritolyl phosphate and dioctyl phthalate.

Title: Method of polymerizing acrylonitrile
IPC: C08F20/44
Filed: 1963-02-13
Abstract: Acrylonitrile is polymerized in dimethyl sulphoxide solution and, when the extent of polymerization is from 70-90%, unreacted monomer is evaporated from the solution while maintaining the solution in the form of a film or layer not more than 2 cm. thick, at a temperature of 20-60 DEG  C. and a pressure of 30-500 mm. Hg. The monomer recovery is effected in an evaporator fitted with revolving discs and into which a gas, e.g. air, inert to the polymerizing solution, is continuously introduced.  The acrylonitrile may be copolymerized with up to 15% of at least one other ethylenically unsaturated monomer of which methyl acrylate and sodium allyl sulphonate are exemplified.  A number of other such suitable monomers are listed and include ethylenic hydrocarbons, carboxylic acids, amides, chlorides, acetates and sulphonic acids. Catalysts such as azobisisobutyronitrile and lauroyl peroxide, colouration inhibitors such as tin compounds, acids and sulphuric dioxide gas, and chain transfer agents such as dodecyl mercaptan and sodium b -styrene sulphonate may be used.

Title: Means and method for reclaiming or re-fining petroleum oils
IPC: C10M175/00
Filed: 1934-02-22
Abstract: <PICT:0433876/III/1> A method of reconditioning used lubricating oils, by heating a mixture of the oils with clay to drive off volatile constituents while agitating by a gas stream and filtering the residue, is characterized by the additional step of contacting the oil after filtration with a cooler metal surface to remove carbonaceous and like suspended matter.  As shown, a mixture of oil and clay such as "Bentonite" in a container B is transferred to a still C, heated electrically or by a burner 10, and, after removal of volatile constituents to a condenser F, is filtered under pressure in a chamber E and passes thence through a copper or like cooling pipe 9 in a vessel A, which may contain oil awaiting treatment. Gas stream agitation in the still C is effected by introducing water in controlled quantities through a pipe X into a closed tube Y within the still and introducing the steam so produced into the oil through a coaxial pipe Z and a pipe 8.  The filter chamber E contains a filter sheet 5, and an underlying screen 15 supported by a plate 6, having an annular clamping rib 24 co-operating with a groove 14.  The plate 6 is carried by a link 16, connected at one end by a link 17 to a lug 18, and at the other end to a screw-threaded link 19.  The link 19 passes through an apertured lug on the filter casing and a spacing block 20, and engages a nut 21 rotatable by a ratchet 22 to tighten the plate 6 against its seating.  U.S.A.

A drilling machine for drilling a printed circuit-board 26 comprises a table 20, a template 21 mounted on the table, a slide 81 carrying the board, which is slidable on guides 82, 84, and a probe 86 carried by the slide for engagement with holes 23 in the templet, to place board 26 in the required drilling position, under a drill assembly 32. The latter comprises a support 33, Fig. 4, enclosing an airactuated piston 36 carrying a drill bush 38 thereon, and a top drill bush 48 carried by the drill head 44, the latter being adjustably secured to an arm 43 by nuts 46. Drill 42 is driven by a motor 65, and is rotatably mounted in a sleeve 52 which is fed by a rack- and-pinion 53, 54, the pinion being rotated by a further rack-and-pinion 70, 68, actuated by an air cylinder 71. In operation, template 21, and board 26, are positioned by pins 29, and 93 respectively, and probe 86 is registered with the first hole 23 in the templet. An arm 89 on the probe, Fig. 7, actuates a micro-switch 90 to supply air to move piston 36, Fig. 4, against spring 37, and to press board 26 against bush 48, and also to supply air to cylinder 71, thus feeding the drill. When the hole is drilled the probe is lifted from the templet, thus opening switch 90, and cutting-off the air supply to allow springs 55 and 37 to retract the drill and bush 38 respectively, the air during this period being supplied to a nozzle 108, Fig. 11, to blow away the chips. Slide 81, along with board 26, is moved along guides 82, 84 until the probe is aligned with the next hole to be drilled, and switch 90 is again actuated. The air supply is controlled by a solenoid valve 101, Fig. 11, actuated by switch 90, and included in the air circuit is a filter 102, oiler 103 and regulator 104. When valve 101 is energized, air is admitted to support 33 through a regulator 105, and conduit 40, and to cylinder 71 through a meter valve 106, and when valve 101 is deenergized the air passes through a conduit 107 to nozzle 108. A suction conduit 109, Fig. 2, is provided for drawing air and cuttings through openings 110, Fig. 4, in drill head 44. In a modification, two circuit-boards are drilled by having the described members duplicated in the machine.

Patent GB-797981-A (GB)
Title: Improved fuel oil compositions
IPC: F02B3/06
Filed: 1957-02-22
Abstract: A hydrocarbon fuel oil composition contains an oil-soluble polymer or copolymer of an alkoxylated partial ester obtained by partially esterifying an unsaturated dicarboxylic acid with an aliphatic monohydric alcohol, and thereafter reacting the remaining free carboxylic acid groups with an alkylene oxide, whereby the free carboxylic acid groups are neutralized.  The dicarboxylic acid may be fumaric or maleic acid, and is partially esterified with an alcohol having 3 to 20 carbon atoms per molecule by reacting less than 2 gram molecules of the alcohol with a gram molecule of the acid.  The partly esterified acid is then reacted with an alkylene oxide containing 2 to 6 carbon atoms per molecule.  The alkoxylated partial ester is then polymerized, or copolymerized with an unsaturated hydrocarbon, such as styrene, an unsaturated ester, such as vinyl acetate, an unsaturated nitrile, such as acrylonitrile, or the anhydride of an unsaturated dibasic acid, such as maleic anhydride. Such alkoxylated partial esters are described in the parent Specification.  The compounds may be added to gasolines, kerosenes, gas oils, diesel oils and to oils for furnaces, directly or as a concentrate in oil, to provide 0.001 to 0.5 grams of polymer per litre of feed.  In examples maleic acid is partially esterified with a C9 oxo alcohol, reacted with ethylene oxide, and copolymerized with vinyl acetate, and the product added to diesel oil.
