Title: Fuel compositions
IPC: C10L1/14
Filed: 1956-08-22
Abstract: A fuel composition comprises a hydrocarbon material boiling in the gasoline, kerosine or gas oil range, and a minor proportion of an at least partially hydrolysed copolymer of a vinyl ester of an aliphatic carboxylic acid having not more than 5 carbon atoms in the molecule and an alpha-olefin having from 10 to 42 carbon atoms in the molecule, the ratio of the number of polar groups to the number of non-polar groups in the hydrolysed copolymer being between 0.5:1 and 10:1.  The vinyl ester may be vinyl formate, vinyl acetate or vinyl propionate.  The olefin may be 1-octadecene, 1-dodecene, or a mixture of straight chain C13 to C18 alpha-olefins.  The polar groups are the hydroxyl and carboxylate groups, and the non-polar groups are the alkyl groups are the parts of the olefin molecules other than the terminal CH1 = CH- groups which enter the copolymer chain.  The ratio of the polar to the non-polar groups is the mole ratio of the vinyl ester to the olefin in the copolymer before hydrolysis.  The copolymer is hydrolysed by reacting with an alcohol and an alkali metal alcoholate to convert some of the carboxylate (or alkanoyloxy) groups to hydroxyl groups, and between 50 and 95 per cent of the groups are hydrolysed.  The copolymer may have an average molecular weight between 4000 and 100,000.  The fuel may be a gasoline, particularly an aviation gasoline, or an aviation turbine fuel, such as kerosine or a gas oil fraction, and contains between 0.1 and 100 parts per million of the copolymer. The composition may also contain tetraethyl lead, iron carbonyl, dicyclopentadienyl iron, xylidene, N-methyl aniline, ethylene dibromide, ethylene dichloride tricresyl phosphate, dimethyl xylyl phosphate, N,N1 - disecondary - butylphenylene diamine, N - n - butyl - p - aminophenol, 2,6 - ditertiarybutyl - 4 - methyl phenol, N,N1 - disalicylal-1,2-propane diamine, polymerized linoleic acids, and alkyl boronic acids.

Title: Signal comparators
Inventor: HIRST ROBERT
IPC: H03J7/30
Filed: 1969-05-20
Abstract: 1,207,098. Automatic frequency control; radio receiving circuits. STANDARD TELEPHONES & CABLES Ltd. 20 May, 1969, No. 25702/69. Headings H3A and H3Q. In a stop on signal receiver (Fig. 1, not shown) the signals, reduced to an intermediate frequency are applied simultaneously to a narrow band filter NF, and a wide band filter WF, e.g. one having a band width three to four times that of the narrow-band filter. The outputs of the two filters are applied to an AND gate, such that when the output levels from the two filters are equal, or within a predetermined degree of equality, there is an output from the AND gate gate which causes relays RL1, RL2 to operate. Relay contacts RL1 then close to allow the output from the narrow band filter NF to reach output circuits, e.g. an AFC circuit, and relay contacts RL2 open to stop the search control motor M. The arrangement ensures that the searching is stopped and the AFC circuits brought into operation when the narrow-band filter passes a wanted carrier and prevents operation on a sideband of lower level (Fig. 2, not shown): it may also be used in frequency synthesizers to avoid locking to a spurious signal.

Title: A method of starting diesel engines under load, particularly diesel engines acting directly on the driving axles of locomotives
IPC: F01L13/00
Filed: 1935-09-17
Abstract: 465,943. Starting. MASCHINENFABRIK AUGSBURG - NURNBERG AKT.- GES. Sept. 17, 1935, No. 25797. Convention date, Sept. 22, 1934. Drawings to Specification. [Class 7 (v)] In a method of starting Diesel engines under load, and particularly Diesel engines acting directly on the driving axles of locomotives, throttled compressed air is introduced into the cylinders before or during the compression stroke, whilst the exhaust valve is still open, the air being so preheated that its final compression temperature, after compression to approximately 10 to 18 atmospheres, is at the commencement of fuel ignition somewhat above the ignition temperature, and further compressed air being introduced subsequently to ignition at a pressure higher than the compression pressure when the combustion pressure has fallen to the level of the pressure of the additional air. The two supplies of compressed air may be taken from separate compressors or from the same compressor ; in the latter case, only the first of the two supplies is throttled. The preheating of the compressed air may be effected in a heat-exchanger or by the combustion of fuel injected into the air. In four-stroke engines, the preheated compressed air is admitted through the inlet valve, which is opened just sufficiently to effect throttling, or through an independent throttle valve, and is partly forced out again through the exhaust valve. If the engine is to work on a twostroke cycle during the starting period, the engine is scavenged and charged by the throttled compressed air entering while the inlet and exhaust valves are open. In a two - stroke engine having piston-controlled inlet and exhaust ports, the preheated throttled compressed air is admitted through additional ports, and the cylinder is scavenged in the outer dead-centre position of the piston, either in the known manner or by the heated and throttled compressed air.

Title: Improvements in and relating to thin-film signal translating devices
IPC: H01L29/73
Filed: 1963-07-01
Abstract: 1,035,785. Electric solid state devices. PHILCO CORPORATION. July 1, 1963 [June 29, 1962], No. 25989/63. Heading H1K. An electric solid state device comprises an insulating layer of the order of tens of angstroms thickness having a layer of cadmium sulphide on one side thereof. In one embodiment, Figs. 5A, 5B, a wafer of N-type germanium 10 has a layer 14 of aluminium (or gold) vapour deposited through a mask to a thickness of 100- 400 angstroms to form a rectifying surface barrier 15. The aluminium is then exposed to air to produce a 20 angstrom layer 16 of aluminium oxide. A cadmium sulphide layer 18 is then vapour deposited through a mask to a thickness of 1 micron, followed by a similarly deposited indium electrode 20 to which a connecting wire 22 is bonded by a globule of silver paste 24. A further electrode connection 26 is made by a globule of silver paste 28 through the oxide layer 16 to the aluminium layer 14. To ensure that such a connection is effective two such contacts may be made and the electrical resistance between them checked. A further electrode connection 12 is made to the body 12. In operation, wires 22, 26 and electrode 12 correspond to the emitter, base and collector of a transistor, the emitter current tunnelling through the oxide layer. The mode of operation is similar to that described in Specification 990,037, but the characteristics are generally improved by the use of the cadmium sulphide layer. In a modification, Fig. 12 (not shown), the collector barrier is formed by an insulating layer of silicon monoxide between the collector electrode and the aluminium layer. In a further embodiment, Fig. 9A, the invention is applied to an " edge-type " device operable in the manner described in Specification 1,002,267. The arrangement is generally similar to that previously described with the exception that the emitter electrode 62 lies directly over the edge of the oxide coated aluminium layer 54, being connected thereto by a cadmium sulphide layer 60. The electrode 62 is biased negatively with respect to the layer 54, so that emission of electrons from the former takes place preferentially near the edge of the latter. Fig. 11 shows a multiple edge device in which the aluminium layer 56 is perforated at 70, 72 to provide a plurality of edges.

Title: Improvements in hydraulic control systems
IPC: G05D9/04
Filed: 1947-09-25
Abstract: 628,235. Regulating liquid levels. OAKES, E. C. Sept. 25, 1947, No. 26011. [Class 123(i)] [Also in Group XXIX] A hydraulic control system for maintaining constant the level of water in a reservoir 4 comprises a head of water in the reservoir which tends to hold closed a main valve 14 controlling entry of water to the reservoir 4 from a source of supply, except when this pressure is relieved by the opening of an exhaust passage 27 by a pilot valve 22 due to the pressure difference between two predetermined levels (at the points 8 and 24) in the reservoir acting on the pilot valve 22. The head of water in the receptacle 7 in the reservoir 4 acts through a pipe 9 to hold the double-headed piston valve 14 in pipe 11 in its upper closed position against gravity, and so prevent the flow of water from pipe 1 to pipe 2 which supplies the reservoir 4. The head of water also acts through the pipe 20 against the pressure of water acting through a pipe 23 from a level in the reservoir determined by the position of the joint 24, the two pressures being applied on opposite sides of valve 22 and mutually cancelling one when the reservoir is at its normal level 6. When however it drops, the pressure on the top of valve 22 falls as the liquid level falls towards the point 24, whilst that from receptacle 7 to the lower side of valve 22 remains constant. Hence valve 22 rises and water from the pipe 9 can flow to waste via pipe 27, and hence the main valve 14 falls and allows water to be supplied to the reservoir until equilibrium is re-established.

Title: Process for the preparation of quaternary ammonium compounds and new quaternary salts obtainable thereby
Inventor: BARBER HARRY JAMES
Filed: 1950-10-27
Abstract: The invention comprises a compound of formula <FORM:0723203/IV (b)/1> where R is Me or Et and A is the residue of 2,2 - dihydroxy - 1,1 - dinaphthylmethane - 3,3 - dicarboxylic acid (embonic acid).  It is made by treating an aqueous solution of another salt of the same quaternary ammonium base with a water-soluble embonate and may be used in the purification of salts of formula <FORM:0723203/IV (b)/2> where R is Me or Et and X is an acid residue.  Thus an impure acid-free aqueous solution of a salt of the above formula is treated to precipitate the insoluble embonic acid derivative which is recrystallized, dissolved in hot water and treated with an acid to precipitate embonic acid and to leave an aqueous solution of the required quaternary ammonium salt from which the latter may be isolated.  Sulphate, nitrate, halide, sulphonate, bisulphate, dihydrogenphosphate, adipate (neutral and acid), benzoate, carbonate, chloride, citrates, acid maleate, metho-sulphate, succinate (neutral and acid) and neutral tartrate are specified salts.  In an example hexamethylene diamine is treated with dimethyl sulphate and the product converted to the corresponding dibromide via the embonate. An embonate may also be obtained from 1,6-bis-dimethylaminohexane after quaternating with an ethyl halide.  Specifications 723,204 and 723,210 are referred to.  The Provisional Specification relates to salts of formula <FORM:0723203/IV (b)/3> where R1, R2 and R3 are lower aliphatic groups and X is as above.
