Title: Manufacutre of an integrated semiconductor circuit
IPC: H01L21/00
Filed: 1971-04-19
Abstract: 1324554 Semi-conductor devices COMPAGNIE GENERALE D'ELECTRICITE 19 April 1971 [23 March 1970] 24777/71 Heading H1K An integrated semi-conductor circuit comprises a chip of monocrystalline silicon 1 over whose surface a silicon dioxide layer 2 is formed, e.g. thermally, and is selectively removed by etching over a photolitho mask to expose the silicon in predetermined zones. Thereafter the exposed silicon is etched into a groove leaving the oxide untouched, after which germanium is epitaxially deposited from gas phase to deposit in monocrystalline form 6 in the groove, and in polycrystalline form 5 overlying the oxide (Fig. 3); the latter being removed by abrasion down to the monocrystalline layers. Portions of the chip are masked by coating with photoresistive resin and exposure to ultra-violet light through a mask covering the germanium-silicon interfaces 7 and other interfaces 8. After development and fixation the substrate is exposed at 7, 8 for etching into recesses. Thereafter an insulant layer 9 of, e.g., silica, alumina, silicon nitride, is formed over the entire surface (Fig. 5) and a polycrystalline silicon layer 10 is deposited thereon, e.g. by reduction of silicon chloride, and the opposite face is abraded down to the polycrystalline silicon in the recesses (Fig. 7) to form capsules of monocrystallinegermanium 6 and monocrystalline silicon 12 supported on polycrystalline silicon substrate 10 and insulated by oxide layers 9. A further insulating groove may be formed and filled with, e.g. gallium phosphide; and the capsules are separately disposed on the substrate (Fig. 8). Diodes and transistors may be formed by thermal doping through an oxide mask into the gallium phosphide and germanium, and by ion implantation into the silicon. The integrated circuit may comprise a germanium infra-red sensitive photodiode, a silicon transistor amplifier, and a gallium phosphide photoluminescent device for conversion to visible light. In the detector germanium is replaceable by silicon, and in the emitter gallium phosphide is replaceable, e.g. by the arsenide, arsenophosphide, or alumino arsenide.

Title: Combining or blending short staple fibres with an endless filament
Filed: 1936-09-12
Abstract: <PICT:0487394/IV/1> <PICT:0487394/IV/2> A continuous filament is rendered tacky and short staple fibre, e.g. rabbit hair and fur, caused to adhere to it while in the tacky condition and the filament being then hardened.  As shown, the filaments 10 are passed between heated rollers 11, 12 to which the short fibre is supplied by nozzles 16, 17.  Excess fibre is collected by a shield 18 and drawn away through a suction pipe 19 and the cooling and hardening of the filaments as they leave the rollers may be accelerated by cool air supplied through nozzles 20, 21.  In a modification the filaments are rendered tacky by passage through a softening bath and are then passed through a trough or apron containing the short staple fibres; the filaments are finally passed through a tank containing hardening solution and the solution may also be sprayed upon the filaments as they leave the trough or apron.  The short staple fibre may be blended with the filaments while they are being formed, the individual filaments 10, Fig. 3, as they leave the spinneret 43 passing into a nozzle 40 to which the short fibres are delivered in a fluid medium through the pipe 45; water or air is used to convey the short fibres according as to whether the filaments are wet or dry spun.  In a further modification the short staple fibre and the spinning solution are both supplied to the spinneret and the fibres may be coated so that they will be impervious to alkalis and acids.

Title: Method of obtaining preparations of castle's intrinsic factor of enhanced potency and preparations obtained thereby
IPC: A61K31/00
Filed: 1953-09-09
Abstract: Animal tissues containing Castle's intrinsic factor are extracted with water at a pH of from 2 to 4, and the aqueous extract is fractionated with a liquid organic precipitating agent consisting of an aliphatic monohydric alcohol or ketone having less than 5 carbon atoms to obtain as a precipitate an intrinsic factor concentrate of enhanced potency.  Hog duodenum or stomach tissue may be employed as the starting material, and it may be comminuted by hashing, or grinding; the frozen tissue may be ground in the presence of dry ice to prevent any loss of activity. The extraction may be carried out at below 15 DEG C.  To the filtered extract ethanol, methanol, acetone methyl ethyl ketone or other aliphatic monohydric alcohol or ketone having less than 5 carbon atoms may be added until its concentration in the extract is between 20 and 60 per cent by volume, the temperature being held below 0 DEG C., and the pH between 4 and 6. The precipitate containing the Castle's intrinsic factor may be separated by centrifuging and purified by solution in ice-cold water and lyophilization.  The pH adjustment for the extraction step may be made by addition of hydrochloric, sulphuric, phosphoric, lactic or citric acid and for the fractionation step by addition of sodium, potassium or calcium hydroxide or sodium or potassium carbonate or bicarbonate.  Detailed examples of the procedure are given.

Abstract: 999,467. Storing animal and vegetable materials. WHIRLPOOL CORPORATION. May 9, 1963 [July 2, 1962], No. 25279/62. Heading A2D. [Also in Division B1] Perishable animal and vegetable materials subject to respiratory deterioration changes on storage in air containing normal quantities of oxygen and carbon dioxide are stored in an atmosphere containing an amount of carbon dioxide greater than that found in ambient air and an amount of oxygen less that that found in ambient air, which atmosphere is produced by burning a carbonaceous fuel in the presence of air in amounts necessary to support substantially complete combustion of the fuel and at a combustion temperature that is beneath the temperature of reaction of oxygen with the nitrogen of the air to prevent formation of oxides of nitrogen, and is passed to a non gas-tight storage chamber for the materials where it continuously replenishes atmosphere escaping from the chamber. Animal and vegetable materials mentioned: apples, grapes, berries, tomatoes, peaches, pears, oranges and bananas; potatoes, carrots, celery, asparagus, onions, beans and peas; milk, butter, cheese and eggs; meat and meat products; grains, nuts, cut flowers, flower bulbs and tobacco. Under preferred conditions, the storage chamber is refrigerated, the atmosphere has 25-100% relative humidity (preferably 85-100%), a temperature between 29‹ and 120‹F. (preferably 29-55‹F.), 1-10% by volume oxygen and 1-15% by volume carbon dioxide. The amount of carbon dioxide may be regulated by passing the atmosphere through a scrubbing tower. A cylindrically-shaped catalytic burner 14, Fig. 2, for the combustion of the mixture of air and vapourised hydrocarbon fuel at a temperature in the range from 1200‹ to 2000‹F., below that at which substantial amounts of nitrogen oxides are formed, has an annular catalytic bed 36 mounted between perforated stainless steel annuli 34, 35, an inlet 28 for the mixture, an outlet 15 for the combustion products and an igniter 41. The air and gaseous fuel are pre-mixed by a blower to provide 20-25% excess air over that required for combustion. Ignition at first takes place within the space 40 until this heats the catalytic bed 36 to a temperature high enough to support combustion. The temperature at which the combustion reaction takes place is regulated by circulation of water in a jacket 37. This water may have been previously employed in chilling the flue gas produced. Catalysts mentioned are chromealumina containing 20% chromic oxide in the form of #-inch extruded pellets and platinum-alumina.

Title: Improvements in and relating to the low temperature distillation of fuel
IPC: C10B7/00
Filed: 1926-10-11
Abstract: 260,569. Plassmann, J. Oct. 27, 1925, [Convention date]. Charging. - A device for feeding fuel into a low-temperature distillation chamber 1 comprises a screw 2 extending within the chamber 1 and movable relatively to it and constructed to effect uniform packing of the fuel across the whole width of the chamber 1. As shown, fuel from a hopper 3 is fed by the screw 2, the shaft of which extends within the chamber 1 and carries inclined surfaces 4 which, when the screw, together with its driving gear, is rotated in the direction of the arrow, cause the fuel to pack uniformly within the chamber 1. The screw 2 is driven bv a worm-wheel 5 which consists of spaced discs 8, 11, keyed at 10 to the screw shaft 9 and having bevelled edges in frictional. contact with a toothed ring 12 driven by a worm 7. The speed of rotation of worm 7 is such that, when the maximum packing effect is obtained in the chamber 1, the ring 12 rotates slightly faster than the screw 2, the speed of the latter being adjusted to produce any desired closeness of packing by adjustment of the spring 6 to vary the space between the discs 8, 11 and thus the friction between these discs and the ring 12. A modification is described in which the inclined surfaces 4 are replaced by a tapering extension of the main screw 2. Specification 240,800 is referred to.
