Title: Improvements in or relating to fuel supply systems for internal combustion engines or like fuel consuming devices
IPC: F02D9/00
Filed: 1947-07-28
Abstract: 662,848. Spray carburetters ; regulating. BENDIX AVIATION CORPORATION. July 28, 1947 [Aug. 10, 19461, No. 20348/47. Classes 7(iii) and 7(vi) A fuel supply system comprises a gear pump 32 feeding a centrifugal impeller 62 which delivers through a conduit 60 to a valve controlled orifice 74, from which the fuel flows through a metering orifice 24 to a discharge nozzle 97 controlied by a diaphragm-actuated valve 98 subjected through a pipe 118 to the fuel pressure upstream of the impeller 62. The orifice 74 is controlled by a needle 78 carried by a diaphragm 90 and actuated by a cam 86 on the throttlevalve spindle. The diaphragm 106, loaded by a light spring 107, actuates a valve 98 to keep the metered pressure in chamber 70 substantially equal to that in pipe 118, so that the impeller 62 maintains a pressure head across the orifice 24 proportional to the square of engine speed for a constant position of the valve 78. A control valve 130 connects the pipe 118 through a groove 132 and conduit 42<SP>1</SP> to the outlet side of pump 32 during normal operation, but at starting an increased fuel supply is obtained by turning valve 130 so that the groove 132 connects pipe 118 to a pipe 120 leading to the inlet of pump 32, reducing the pressure in space 70 and hence increasing the pressure drop across orifice 24. The valve 130 can also be turned at stopping so that a groove 134 connects the pump outlet 42<SP>1</SP> to its nlet 20. and the impeller 62. is cut off from the pump 32. The needle 78 may be contoured for slow-running and full power enrichment, and the cam 86 may be provided with a depression so that valve 78 is fully open when the throttle valve 14 is wide open. The fuel system may include the economizer, acceleration device, and temperature responsive device described in Specification 662,837, the priming means described in Specification 662,847 and a plurality of nozzles may be fed by a distributer as described in Specification 662,838. The speed of the impeller 62, which may be driven through a fluid.,drive or by variable speed pulleys, may be varied by means responsible to atmospheric pressure to correct the fuel-air ratio for varying altitude.

Title: A process for sensitising electrophotographic layers
Inventor: SIMM WALTER
IPC: G03G13/22
Filed: 1963-05-22
Abstract: 1,020,831. Electro-photographic processes. AGFA A.G. May 22, 1963 [June 16,1962], No. 20476/63. Heading G2H. [Also in Division H1] An electrophotographic material is sensitized by forming an electrostatic charge image on the photo-conductive layer and treating the layer with a sensitizing dyestuff in such an amount that the sensitizing dyestuff is deposited in a practically invisible pattern corresponding to the image. The process is utilized in several ways. In the first, an unsensitized material is given a uniform negative charge, exposed to a picture image, and developed with a positively charged aerosol containing the sensitizing dyestuff. The material is allowed to stand in the dark for some hours and is then recharged negatively and exposed uniformly to a diffuse light source. When developed a reversed image of the original is formed. In the second use, an unsensitized material is negatively charged, exposed to a screen image, developed with a positively charged aerosol of the sensitizing dyestuff, allowed to stand in the dark, exposed to a picture image using light to which both sensitized and unsensitized regions of the plate are sensitive (perhaps to different extents), and developed to obtain a non-reversed half-tone image. In another screen process a multiple screen may be produced by using dyes which are sensitizers for different wavelengths, the differently sensitized regions being formed so that they do not, or at the most only partly, overlap. Materials of this type are used for the subsequent development of multicoloured images. In the particularly described embodiments development at all stages is carried out using electrostatically atomised positively charged aerosols but in general the dyestuff sensitizer may be applied to the photo-conductive layer by known processes using either solutions of the dyestuff or the solid dyestuff. Cascade and dust cloud processes are possible using the powdered dyestuff to form a dry powder image which is fixed by aftertreatment with a solvent, and processes may be used which depend on the different wetting capacities of charged and uncharged regions of the material.

Abstract: 597,107. Oscillating motion gearing. VERZINKEREI ZUG AKT.-GES. Aug. 9, 1945, No. 20495. Convention date, May 25. [Class 80(i)] An oscillating motion gear, e.g. for driving a washing machine having perpendicular driving and driven shafts 1, 4, has a bevel wheel 3 rigid with the shaft 1 and a meshing bevel wheel 8 mounted fast on an arm 9 for oscillation about an axis II which passes through the point of intersection of the axes I, III, of the shafts 1, 4 respectively, the axis of rotation IV of the bevel 8 subtending an angle of less than 90 degrees with the axis I. The bevels are maintained in mesh by a freely mounted arm 10 and a link 11. Rotation of the shaft 1 causes a synchronous rotation of the arm 10, retaining the bevels 3, 8 in mesh, and rotation of the bevel 8 in the opposite sense, and the sum of these two rotations causes the bolt 7 to oscillate in the plane of the axis I thus imparting oscillating motion to the arm 6 of the carrier 5 secured to the driven shaft 4.
