  • Patent number: 4807812
    Abstract: A fuel injector for a petrol engine has an outer annular body and a core member mounted therein. The core member has a central passage which leads from a fuel inlet to adjacent a plate-like valve member which is biased into contact with a seat ring by a spring. The core member is surrounded by a solenoid winding which when energized causes the valve member to lift from the seat ring to allow fuel flow through an outlet orifice. The fuel is conveyed from the inlet to adjacent the valve member by a tubular member which is mounted in spaced relationship within the passage.

  • Patent number: 4807908
    Abstract: A ballot consisting of two or more ballot cards is held together by means of perforated creases. The resulting ballot is printed in columns and rows entirely on one side representing a similar ballot format as presented to the voter on the face of the mechanical or fully electronic machine used in that election jurisdiction. Positions for write-in candidates would normally appear on the back of the ballot. After the ballot cards are punched or marked by the voter, they ar detached from each other. The ballot cards are then machine read and tallied. One end of the ballot cards may be provided with a receipt stub attached thereto by a perforated crease. The receipt stub may be given to the voter for record purposes. Unique pre-punched holes or marks on each card of the total ballot identify to the card reading equipment which part of the total ballot is being processed.

  • Patent number: 4804444
    Abstract: A method of producing both-side electrolytically zinc plated steel strips utilizing a chloride bath including the steps of plating one side of the steel strip in a first plating cell, wetting the thus one-side plated steel strip in a wetting tank, and then plating the other nonplated side of the steel strip in a second plating cell. The method provides for limiting the concentration of zinc in the wetting solution to a range of 0.1-50 g/l so as to improve the zinc coating coverage, glossiness and corrosion resistance.

  • Patent number: 4803764
    Abstract: A process is disclosed in which a rectangular spacer frame (16) for insulating glass is automatically manufactured in that a tubular bar is repeatedly bent in a common bending plane (5) and its free ends (19, 20) are joined. One or both end portions of the tubular bar are deflected out of the bending plane (5) during the final bending operation so that the free ends (19, 20) are moved to such positions that said extremities are laterally spaced apart and extend alongside each other. The end portions (17, 18) of the tubular bar are then gripped and moved to positions in which they are axially aligned and spaced apart. The free ends of said end portions are subsequently joined to each other to form the spacer frame (16), which is subsequently transferred to an overhead conveyor (69) in an automatic operation.

  • Patent number: 4802453
    Abstract: A fuel injection pump of the rotary distributor type has a fluid pressure operable piston connected to a cam ring of the pump for the purpose of timing adjustment. Flow of fluid into or out of one end of the cylinder containing the piston is controlled by a valve member slidable in a bore in the piston. The valve member is pressure balanced and is positioned by means of control pistons in response to variation in fluid pressure. The piston is subject to reaction forces when the cam followeres of the pump engage the leading faces of the cam lobes and the tendency for piston movement is resisted by a ball valve. Opposite reaction forces occur when the cam followers move over the crests of the cam lobes and piston movement is resisted by restricting liquid flow from the other end of the cylinder.
