Title: Rotary fuel-injection pump
IPC: F02M41/14
Filed: 1969-04-22
Abstract: 1,262,542. Fuel-injection pumps. BENDIX CORP. April 22, 1969 [April 22, 1968], No.20538/69. Heading F1A. In a fuel-injection pump for an I.C. engine fuel is fed to a chamber 60 between diametrally-opposed pistons 68 within a rotor 30 by a rotary pump 28 through passages 58, 59, said rotor being driven by the engine through a shaft 26 and engaging with an axially-movable valve-member 32, which aided by a variable throttle-valve 33 regulates the quantity of fuel entering delivery passages 83 sequentially from said chamber by way of a passage 81 and axial groove 82. While either of mutuallydivergent grooves 91, 92 is in register with any one of radial passages 85 fuel spills out of the groove 82 through an annular groove 84, said passage, the groove 91 or 92, a groove 93, a chamber 87, a passage 94, an annular groove 95, the valve 33 and a passage 97 into the fuel tank. Owing the divergence of the grooves 91, 92 axial movement of the member 32 changes the time interval during which fuel flows from the groove 82 into the respective passage 83. An orifice 104 in a spring-loaded valve-member 102 of the valve 33 is in a groove 107 so that throttling can be varied by a lever 112. The setting of the member 102 determines the pressure in the chamber 87 and hence the axial location of the member 32 owing to the provision of a spring 90. Axial movement of the member 32 is limited by a slot 89 therein engaging with a pin 88, which is lodged in slots 133 in a sleeve 100 fixed to an adjusting nut 98. Movement of a spring- loaded transverse-plunger 126 in response to changes in the output pressure of the pump 28 (according to engine-speed variations) moves the pin 88 within portions 134 of the slots 133 and thereby partially rotates the member 32 so as to alter the timing of the registration of the grooves 91, 92 with the passages 83. When the engine speed becomes high the pin enters helical portions 135 of the slots 133 and thereby causes axial movement of the member 32 in addition to a further changes in said timing, the axial movement reducing the engine torque to accord with the speed. A by-pass valve 27 regulates the output pressure of the pump 28 and facilitates escape of leakage fluid. The pistons 68 have rollers 71 thereon engaging with a fixed cam-ring 61.

Title: Improvements in the electrolytic recovery of copper from alloys
IPC: C25C1/12
Filed: 1932-07-22
Abstract: 386,896. Electrolytic recovery of copper. LEWIN, T., St. Louis, Missouri, U.S.A. July 22, 1932, No. 20742. Drawings to Specification. [Class 41.] In the electrolytic recovery of copper from brass, bronze and other alloys employed as anodes, the anode slime, containing tin and lead together with some copper, copper sulphate and insoluble copper compounds, is oxidized by roasting and used as an agent for flocculation and precipitation of impurities colloidally suspended in the electrolyte and for restoration of its copper and acid content. The initial electrolyte may contain 8-12 per cent of sulphuric acid and 3-5 per cent of copper sulphate. In an example, a portion of the electrolyte is withdrawn from the cells to a vessel where it is agitated with the roasted slime, which is introduced while still hot. The liquid passes to further vessels into which live steam is introduced. Nodular matter settling from the slimes is returned for reroasting. The liquid then passes to a heat-insulated settling tank from which it is returned to the cells ; the sediment from the tank is withdrawn for treatment. Specification 269,253, [Class 41, Electrolysis], is referred to.

Title: A process for the preparation of nitro compounds of tetrahydronaphthalene and its derivatives
IPC: C07C13/48
Filed: 1920-07-10
Abstract: The Specification as open to inspection under Sect. 91 (3) (a) states that nitro-compounds of tetrahydronaphthalene may be reduced to the corresponding amino compounds by hydrogen in the presence of a suitable metal or metal oxide. The reduction of dinitro-tetrahydronaphthalene in tetrahydronaphthalene solution is described. This subject-matter does not appear in the Specification as accepted.ALSO:Nitro derivatives of tetrahydronaphthalene are obtained by treating tetrahydronaphthalene with a mixture of nitric and sulphuric acid, or other nitrating mixtures such as nitric acid and acetic acid, containing not more than 25 per cent. of water, the temperature being maintained below 50 DEG C. during the earlier stages of the process. The homologues of tetrahydronaphthalene substituted either in the aromatic or cyclobexane ring by methyl, ethyl, &c. groups, and also the amino or hydroxy derivatives of tetrahydronaphthalene substituted in either ring may be nitrated similarly.  Examples are given of the preparation of a mixture of a - and b -mononitrotetrahydronaphthalene, a mixture of dinitrotetrahydronaphthalenes, and a trinitrotetrahydronaphthalene. The dinitro compounds may be used as an ingredient of explosives, in admixture with potassium chlorate, ammonium nitrate, &c.  The Specification as open to inspection under Sect. 91 (3) (a) contains also the following subject-matter.  On oxidation, the dinitro compound yields 3 : 5-dinitrophthalic acid.  Reduction of the nitro-compounds by the usual methods, e.g. by tin or stannous chloride and hydrochloric acid, or by sodium hydrosulphite or by hydrogen in the presence of a catalyst, gives the corresponding amino derivatives of tetrahydronaphthalene etc.; as intermediate stages of reduction may be obtained hydroxylamine, hydrazo, azo, or azoxy compounds, the hydroxylamine derivatives may be rearranged to the p-aminooxy compounds and the hydrazo compounds to the corresponding benzidine derivatives. Examples describe the reduction of the mixture of mononitro compounds to a mixture of a - and b -aminotetrahydronaphthalenes, and of the dinitro compound to the nitroamino compound by sodium hydrosulphide and to the diamino compound by hydrogen in presence of a catalyst. Acetyl compounds of a - and b -aminotetrahydronaphthalenes and benzoyl and benzylidene derivatives of the diamino compound are also described.  This subject-matter does not appear in the Specification as accepted.

Title: Process for preparing a freeze-thaw stable acrylate latex
IPC: C08F22/00
Filed: 1962-05-30
Abstract: 940,366. Freeze-thaw stable acrylate latex. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. May 30, 1962 [June 1, 1961], No. 20823/62. Heading C3P. A freeze-thaw mechanically stable latex is prepared by copolymerizing a monomer mixture comprising from 2 to 60% of styrene or a ring- substituted styrene, from 35 to 97À5% of an alkylacrylate having from 4 to 12 carbon atoms and from 0À5 to 5% by weight of an alpha-beta vinylidene carboxylic acid, in an aqueous emulsion containing a water-soluble anionic emulsifier and an oil-soluble anionic emulsifier, preferably together with a non-ionic emulsifier, the catalyst being a redox catalyst i.e. an oxidising catalyst to which is added a reducing agent, and the temperature of the reaction mixture being maintained between 15 and 85 C. The preferred monomer mixture comprises 4 to 40 % of styrene, 55 to 95 % of an alkylacrylate having from 4 to 7 carbon atoms and from 1 to 3% of acrylic or methacrylic acid. Specified water-soluble anionic emulsifiers are salts of organic sulphates such as an alkali metal salt, e.g. the sodium salt, of an alkyl-aryl-polyethoxy-ethanol sulphate and oilsoluble anionic emulsifiers specified are alkyl esters of a sulphosuccinic acid salt e.g. the dihexyl ester of sodium sulphosuccinic acid. Preferred nonionic emulsifiers are the octylphenolethylene oxide condensation products and condensation products of ethylene oxide with alcohols or other alkylphenols. Oxidising catalysts mentioned are water-soluble or partially water-soluble hydroperoxides or persulphates e.g. tertiarybutyl hydroperoxide and ammonium persulphate while the reducing agent may be ferrous iron or sodium hydrosulphite. Preferably the process is carried out by mixing the monomers together, mixing water and both anionic emulsifiers or both anionic emulsifiers together with part or all of the nonionic emulsifier to provide an emulsion consisting of the monomer mixture, emulsifying agent and the peroxide catalyst and then treating a portion of this mixture with sufficient reducing agent to begin the reaction and then adding further emulsion and reducing agent. When the polymerization is complete, the emulsion is stripped of unreacted monomer and neutralised and then made alkaline with ammonium hydroxide. Additional stabilizers and/or protective colloids or other additives may be added to the emulsion latex e.g. sodium polyacrylate may be added. The acids used in the examples are methacrylic and itaconic.

Title: Digital control of the movement of apparatus parts such as the movable members of x-ray diffractometers
IPC: G01N23/20
Filed: 1965-05-17
Abstract: 1,111,266. Digital control systems. W. HOPPE. 17 May, 1965 [15 May, 1964], No. 20863/65. Heading G4H. In a digital control system for controlling the movement of a part of an apparatus there is a motor for moving the part and coarse and fine digital control arrangements, the coarse control being incremental, operable in accordance with a predetermined number of steps of the motor, and the fine control comprising a digital encoder rotating with the motor to produce a position signal for comparison with a stored coded number representing the desired position of the part. The desired position represented by a decimal number is entered into a store #α, e.g. from a tape. The most significant digits of this number are compared with the contents of a counter 9 which receives a pulse for each pulse applied from oscillator 5 through gate 1 to the motor 6. When the numbers agree an output B from comparator 7 resets flip-flop FF2 to close gate 2 and prevent further pulses reaching the motor. It also initiates the fine control by enabling the digital encoder. This may be done by switching on the lamps L if the sensing is photo-electric, or by energizing a solenoid to bring sensing contacts into engagement with the coded scale if this is conductive. The output of the encoder is compared in diode gates 3 with the least significant digits of the number stored and if further adjustment of the motor is necessary a signal is passed via gate 2 to flip-flop FF2 to open gate 1 and allow another pulse to pass to the motor. This check is made after each pulse until agreement is reached. A number of motors may be controlled e.g. to move parts in three co-ordinates. All the motors are supplied from the same oscillator and a single counter is used. As each reaches its required coarse value it switches to the fine control.
