Abstract: A clip assembly for attachment to a flexible gasket which has at least one opening therethrough, the assembly imparting sufficient rigidity to the gasket for convenient transportation and handling. The assembly consists of two plate members extending in overlaying relation with one another and with the gasket, one member having an expandable protrusion easily slid into the gasket opening and the other member having a projecting pin which produces expansion of the protrusion to thereby secure the gasket to the assembly.

Abstract: A device for transmitting linear motion into rotary motion, particularly as applied to an oil pressure transducer for a vehicle I.C.E. Specifically, the linear movement is produced by action of pressure against a diaphragm as opposed by a yieldable spring. The spring is a wire curved into a helix shape and with the ends attached to a rotary table. The midportion of the spring is operably attached to the central portion of the diaphragm so that linear movement thereof toward the rotary table causes the spring's end portions to progressively engage the table in overlying relation and, accordingly, to produce rotation of the table.

Abstract: A pressure transducer to measure and indicate fluid pressure levels including a housing in which a diaphragm and piston assembly is movable in response to pressure changes, the piston having a portion extending therefrom to engage a switch contact thereby disengaging the switch when the fluid pressure falls below a desired level.

Abstract: This application concerns a turbocharger control system and apparatus in association with a variable exhaust flow type turbocharger in which flow regulating turbine inlet vanes are positioned. The control includes a fluid pressure responsive device for actively positioning the inlet vanes. The device responds to opposing fluid pressure generated forces both of which are regulated in accordance with a program responsive to engine and vehicle parameters. The fluid pressures are the engine's intake manifold vacuum or pressure and the turbocharger's compressor output.

Abstract: In a fill tube of a vehicle fuel tank, an inlet forming device for receiving the nozzle of an associated fuel pump for filling the fuel tank and including an apertured seal member adapted to encircle the fuel nozzle to prevent fuel vapors from escaping therebetween. The device includes at least one vent opening which is normally blocked by an overlying edge portion of the seal member, but which is movable from its overlying position outward to vent fuel tank pressure. The overlying portion of the seal is normally biased to a closed position by the natural resiliency of an adjacent open celled foamed plastic material which also acts as a filter when the overlying edge portion of the seal is moved to a more open vent position.

Abstract: A fluid pressure transducer having a hollow enclosure with an elongated tubular guide supported therein around which a tubular piston moves in response to fluid pressure forces acting on one piston end. A spirally-wound wire resistance coil on the guide is contacted by one end of a conductor carried by the movable piston to effectively charge resistance through the conductor and parts of the coil. The conductor is connected to one end of a metal spring which opposes piston movement due to pressure forces. An opposite end of the metal spring is connected to a terminal to transmit the resistance changes.
