Filed: 1974-08-08
Abstract: 1485836 Supplying liquid and gaseous fuel to IC engines NATIONAL AERONAUTICS & SPACE ADMINISTRATION 8 Aug 1974 [10 Aug 1973] 34938/74 Heading F1B [Also in Division C4-5] Combustible mixture is supplied to an I.C. engine  by an induction system which includes gas supply means (20), Fig. 8 (not shown) connected to supply hydrogen rich gas at a substantially constant rate and an elevated pressure to fuel mixing means and liquid fuel supply means connected to supply liquid fuel to the fuel mixing means which includes an atomizer 46. The rate of supply of liquid fuel to the atomizer is controllable by control valve 40 up to a maximum rate which is determined in relation to the air flow-rate by an over-ride means 48, 60-68 so that the equivalence ratio of the air fuel mixture does not exceed a predetermined value. The liquid fuel passes to the mixing means via a pipe 26 and its flow to a passage 76 of atomizer 46 is controlled by lever 43 in conjunction with the air fuel mixture flow-rate controlled by throttle valves 54, 56. The maximum distance the lever 43 can move to the right is greater for greater air flow-rates because a cam 68 is caused to rotate by a piston 60, which responds to Venturi vacuum. Of the three positions shown for the lever 43, the left corresponds to closed throttle, the right to maximum throttle at maximum RPM and the intermediate solid line position corresponds to maximum throttle at idle RPM. Under idle conditions, the fuel supplied to the engine is substantially entirely gas and at full load and RPM mainly liquid hydrocarbon fuel. The hydrogen rich gas is formed by supplying a mixture of gasoline, water and atomizing air to a chamber enclosed by a wall (106) via pipes (94), (96) and (118), Fig. 8 (not shown) for a steam reforming reaction with a mixture of gasoline and air supplied via pipes (94) and (110) to an atomizer (104) and air supplied via pipe (92), a spiral passage surrounding the wall (106) and passages in an air swirler (112).

IPC: B27K3/52
Filed: 1968-07-23
Abstract: 1,270,659. Chlorinated phenol/chromic acid salt preservative compositions. ALBRIGHT & WILSON Ltd. 23 July, 1969 [23 July, 1968], No. 35200/68. Heading A5E. A process for preserving woody cellulosic materials comprises applying to the material an organic solvent solution of a chlorinated phenol having one or more hydroxy groups bound to a benzene ring and 1-5 chlorine atoms bound to the same benzene ring which is optionally substituted by one or more hydrocarbon groups of a salt of such a phenol soluble in the solvent, and a salt of chromic acid with an organic base which contains at least one straight or branched chain containing at least 6 carbon atoms, which salt is sufficiently soluble in the solvent to provide a solution containing at least 0.2% w/v CrO 3  (equivalent) at 20C. Suitably the organic bases are primary, secondary and tertiary amines, quaternary ammonium bases, substituted guanidines, biguanides and s-triazines possessing at least one branched chain in the molecule. Preferred salts are formed from the secondary or tertiary alkyl primary amines (C 6-22 ) or guanidine derivatives thereof. Exemplified are 2 - ethyl - n - hexylamine, di(2 - ethyl - n - hexyl) amine, tri (3,5,5 - trimethyl - n - hexyl) amine, mixtures of tertiary alkyl primary amines (C 12-14 )   and (C 18-22 ) and their 1,5-dialkyl biguanide and N,N'N"-trialk and a mixture of secondary alkyl primary amines derived from n-undecane. The salts have the general formulµ B 2 H 2 CrO 4  or B 2 H 2 Cr 2 O 7 , where B represents one molecule of a monoacidic base. The invention provides that the chromium salts may be employed singly or in admixture one with another. The chlorinated phenols employed are preferably tri-, tetra- or pentachlorophenols but tri and tetrachloro cresols, chlorinated bis phenol A, the trichloro xylenols, tetrachloro o-phenyl phenol and chlorinated hexyl phenols may be used. Other preservatives agents may also be used in the composition, e.g. copper naphthenates, solubilised copper 8-quinolinate, triorganotin compounds such as tributyltin oxide and its derivatives, and solvent soluble salts of arsenic acid with suitable organic bases, e.g. the mixtures of tertiary alkyl primary amines containing either C 12-14  or C 18-22 . The cellulosic material may be treated by applying the composition by brushes or rollers or by dipping. Alternatively the material may be impregnated by exposing the material to be treated to a solution of the treating material under pressure. Suitable solvents include aromatic hydrocarbons, petroleum hydrocarbon solvents, or mixtures of petroleum hydrocarbon solvents with aromatic hydrocarbons and/or ketones. The composition may also include insecticidal agents such as lindane and anti-blooming agents such as dibutyl phthalate. The invention finds particular application when the cellulosic material is wood, plywood, chipboard or hardboard.

Abstract: 1,137,354. Semi-conductor devices. MULLARD Ltd. 28 March, 1966 [19 Aug., 1965], No. 35625/65. Heading H1K. A semi-conductor device comprises a layer of an A III  B V  compound epitaxially deposited on a layer of a substituted A III  B V  compound of narrower band gap formed by diffusing the substituent into an A III  B V  compound body. In one embodiment indium is diffused into the surface of a tin-doped N-type gallium arsenide wafer to convert it to indium gallium arsenide to a depth of up to 10Á. P-type zinc doped gallium arsenide is then epitaxially deposited from a reaction mixture of hydrogen and the chlorides of gallium and arsenic. Subsequently a silicon oxide layer is deposited by reaction of dry oxygen with tetraethyl silicate and the wafer heated to redistribute the impurities and the diffused-indium. As a result the PN junction is relocated in part of the epitaxial layer converted to indium gallium arsenide by out diffusion of the indium. Holes are etched in the oxide to the epitaxial layer using photoresist techniques and gold-zinc alloy electrode material vapour deposited over it. After covering the alloy in the holes with a cerric resist and removing the remaining alloy the assembly is heated to bond the alloy to the layer and the wafer diced to form individual photo-diodes. These are soldered to headers and encapsulated after removal, if desired, of the oxide masking. Photo-diodes may similarly be formed by deposition of gallium arseno-phosphide on the diffused wafer, or of gallium phosphide on a gallium arsenide wafer surface diffused with phophorus. The junctions may also be used as the collectors of opto-electronic transistors. Thus a P-type collector region may be formed by diffusing indium into the walls of a cavity in one face of a gallium arsenide wafer, the base by epitaxially growing the arsenide in the cavity and the emitter by diffusing acceptor into the base.
