Abstract: An anti-rotation clip for joining a fuel injector body to a fuel rail socket. A C-shaped base is formed to slide into an annular groove in the injector body. A pair of tangs extend from the base to straddle a rib on the injector body to prevent rotation between the clip and the injector. Opposed sidewalls extending from the base include windows for receiving a radial flange of the fuel rail socket to correctly position the fuel injector axially within the socket. Each window is divided by a locking bar for reception in a notch in the socket flange to prevent rotation between the clip and the socket. The radial positions of the injector rib and flange notch are selected such that the injector will be properly oriented with respect to the engine after installation therein.

Abstract: A method and apparatus for interfacing graphically with a user of a computer system having selecting means, and display means, which identifies a relationship structure between physical objects and activities external to the computer system which are related to the information to be manipulated in the computer system. At least one data structure is created which corresponds to the identified relationship structure. A plurality of on-screen objects which correspond to information identified in the physical objects and activities external to the computer system is displayed on the display means. A user selection is detected among the displayed on-screen objects, where each on-screen object has initial size and position states. Intermediate and final size and positions states for each on-screen object are prepared according to the data structures.

Abstract: The invention is directed to a cleaning fan for an agricultural combine having a snap in mounting assembly for attaching fan blades to the cleaning fan. The cleaning fan comprises at least two wheels, with each wheel having a series of radially extending mounting teeth. The mounting teeth are provided with snap in mounting assemblies comprising inner and outer transverse grooves between which are located inner and an outer projections. The inner groove is located at the outer periphery of the wheel and the outer groove is located on the outer projection. A spring is located between the inner and outer projections. The fan blades are provided with rectangular mounting apertures which engage the projections.

Abstract: An electromagnetic fuel injector has an orificed fuel director plate, mounted downstream of a solenoid actuated valve and an associated main orifice passage opened and closed by the valve, to receive fuel when the valve is pulled to an open position from its associated valve seat for controlling and directing flow from the injector. The upper surface of the orifice director plate is provided with a fuel distributing channel system terminating in separate pairs of cooperating injection orifices that are disposed adjacent to one another to direct adjacent jets of fuel which partially intersect one another producing discrete cones of atomized fuel accurately onto separate fuel intake valves of a piston cylinder of an internal combustion engine.

Abstract: A system for chaff deployment which includes a compartmentalized platelet with the bottom of the compartments formed by preformed releasable tang springs and the top of the compartment by a releasable door. The door is released to open the chamber and the tang springs are thereafter released to eject and deploy the chaff contained in the chamber.

Abstract: In an evaporative control system for reducing emission of fuel vapors from an engine fuel system there is provided a vacuum operated valve arrangement having a two-position valve which is spring biased to open to permit venting of fuel vapor from a carburetor fuel bowl to a carbon canister when the engine is not running and is responsive to engine vacuum only above a predetermined negative pressure to close to prevent such venting when the engine is running, and a check valve and bleed valve arrangement which is operable to trap engine vacuum at the two-position valve at a vacuum at or above the predetermined negative pressure whenever the engine vacuum drops below such pressure to thereby maintain the two-position valve in its closed position preventing fuel vapor venting during engine running at low engine vacuum and operating to release the trapped engine vacuum at the two-position valve to thereby permit the valve to open to permit fuel vapor venting when the engine is not running.

Abstract: A vacuum actuated switch has a pair of snap action contacts which are actuated in response to the operation of two vacuum motors. One vacuum motor controls the opening and closing of the contacts in a first predetermined range of vacuum. The other vacuum motor extends the range of operation to a second and larger predetermined range of vacuum wherein one limit of the second range is the same as the first range.
