Patent GB-465329-A (GB)
Title: Improvements in and relating to fuel supply systems for internal combustion engines
IPC: F02B39/12
Filed: 1936-07-30
Abstract: 465,329. Spray carburetters. AUTO UNION AKT.-GES. July 30, 1936, No. 21081. Convention date, Aug. 7, 1935. Addition to 446,144. [Class 7 (iii)] In a fuel-supply system operating periodically with suction or supercharging and in which the compressor is provided with a separate suction pipe to permit selection of the optimum sizes of air opening and fuel nozzle therefor, as claimed in the parent Specification, the change over from suction to pressure operation takes place substantially instantaneously after the precompressor has attained or almost attained its full output and the reverse change occurs, after the compressor has been shut off, in the same manner. An induction manifold 1 is supplied alternatively through a suction conduit 2 or a pressure conduit 3 leading from a compressor 4 provided with a separate suction inlet conduit 5. Throttle valves 15, 20 controlling the conduits 2, 3 are interconnected by a link 34 and operated by an extensible rod 42, 43 which connects them with the control of a fuel cock 32 associated with the supply to the compressor. The cock 32 is actuated through a rod 30 by a spring-pressed stud 29, and an arm 23 connected to the rod is adapted to operate a cock 24 in an oil pressure line to actuate a piston 26 which engages the clutch 28 of the compressor. Depression of the stud 29 by an arm 21 on the accelerator pedal 14 simultaneously opens the cocks 24, 32 and tensions the rod 42, 43, the change over valves 15, 20 being locked in the position shown by interengaging hooked arms 37, 40 on the throttle valve 20 and a lover 39 actuated by a piston 17 in communication with the pressure conduit 3. As pressure builds up in the conduit 3, the piston 17 disengages the hook 40 and the rod 42, 43 instantaneously effects the change over. The depression of the accelerator pedal 14 also tensions an extensible rod 12, 13 connecting the pedal to a throttle valve 11 in the suction conduit 2 and thereby permits a rigid two-armed lever 44, 45 to move off a cam 46 and engage its lower arm 45 behind a stop 47 on the rod 30 to look the throttle valves in the pressure operation position. On lifting the accelerator pedal 64, the cam 46 removes the arm 45 from the stop 47 and the change over to suction operation takes place.

Abstract: A synthetic silicate of formula nSiO2, MxOy, mH2O where n is between 0.5 and 15, m is between 1 and 5 and MxOy is a metallic oxide or mixture of metallic oxides, is prepared by reacting a freshly prepared organosol of monomeric silicic acid with a metallic hydroxide so that the medium pH becomes immediately greater than 7, and subjecting the formed organic dispersion to evaporation and drying.  The organosol is prepared by first forming a silica aquasol, e.g. by neutralizing completely or partially a mineral acid or lower aliphatic acid, e.g. formic, acetic, tartaric and glycollic acid, with an aqueous solution of sodium or potassium silicate.  The aquasol is diluted with up to 2 volumes of a strongly polar organic liquid, e.g. acetone, isopropanol and mixtures thereof, adding a water soluble salt, e.g. NaCl preferably to saturation, and separating the organic layer.  The metal hydroxide may be that of an alkaline earth metal, magnesium, aluminium, zinc, zirconium, nickel, magnanese, cobalt or lead.  Aluminium, zinc and zirconium hydroxides are added in solution or suspension in an alkaline lye.  The others may be used as freshly precipitated, or in dispersion in, e.g. the same organic solvent as is used for the organosol.  The hydroxides of lead, nickel, manganese and cobalt may also be added in an alkaline lye.  The dried product may be used as an opaquing filler in papers, resins and paints, as a reinforcing filler in rubber or as an ion-exchanger.ALSO:Synthetic silicates of formula n SiO2, MxOy, mH2O where n is between 0.5 and 15, m is between 1 and 5 and MxOy is a metallic oxide or mixture of metallic oxides, and characterized by the method of their preparation (see Division C1) are used as opacifying fillers for paper.

Abstract: A semi-conductor layer, e.g.Si or Ge, is deposited from the gas phase on a semiconductor body of different electrical properties e.g. Si of different conductivity and then provided with a layer of SiO2 without intermediate exposure to the atmosphere.  The layers may be applied by evaporation in vacuum or by heating the body first in a stream of decomposable compound of the semi-conductor, e.g. a silicon-halogen or silicon-hydrogen compound, or germanium chloride, and secondly in a gaseous compound, e.g. methyl or ethyl silicate or alkoxy silanes, which decomposes to SiO2, with optional intermediate rinsing with H2 or a rare gas.  If the first layer is Si, then moist O2, which oxidizes the surface to SiO2, may constitut the second stream, but it is preferably formed by adding O2, CO2 or H2O vapour to the first stream and modifying the proportions.  Both streams may also contain H2, and then oxygen in the second stream may be added in a form, e.g. SO2CO2, or methanol vapour which reacts with H2 to give H2O vapour. In Fig.1 (not shown) Si body 9 on support 8 of Si or C is heated to 1300 DEG C. in H2.  The temperature is then reduced to 1250-1260 DEG C. and SiCl4 or SiHCl3 is decomposed to form Si layer 13.
