Abstract: A carburetor throttle and choke control mechanism incorporating a choke-throttle cold-start fast idle setting latch mechanism having, in a first embodiment, a blade of a fast idle lever specially contoured for creating upon interengagement with a tang on a throttle lever initial torque resistance to co-rotation of the fast idle lever toward latched condition and then effecting force reversal for creating aiding torque to accelerate the fast idle lever relative to choke lever and thereby open a gap in the push coupling that remains in the latched position of the choke and throttle valves. The choke lever has a relatively rigid pusher leg portion adapted for abutment in push relation with a fast idle lever tang. In a second embodiment an extension of the leg portion in the form of a generally U-shaped resilient spring hook portion is adapted to overlap the tang and releasably hook engage the same when the leg portion is brought into full push abutment with said tang.

Abstract: An illumination assembly and a method for making it. The basic assembly includes an elongated waveguide and an enclosure operative to support an illumination source, where the enclosure defines at least one opening. The waveguide includes light-directing structure operative to direct light out of the waveguide in a pre-determined direction. The end of the waveguide and the opening of the enclosure are each shaped so that the waveguide may be inserted into the enclosure in only one rotational orientation. The method includes the basic steps of: modifying the waveguide to include light-directing structure along the waveguide to direct light out of the waveguide in a predetermined direction; forming an opening having a predetermined shape; and forming the end of the waveguide to have a corresponding shape, where the shapes of the opening and the end permit mating of the end into the opening in only one rotational orientation.

Abstract: A rotary throttle valve carburetor for a two cycle engine reroutes a portion of intake air and introduces the air around the circumference of a fuel feed tube. A rotary throttle, rotatable and vertically moveable, fits into a cylindrical chamber intersecting an air intake channel through a carburetor body. A needle supported by the rotary throttle fits into the fuel feed tube which extends from a fuel metering chamber within the carburetor body into a throttling bore extending laterally through the rotary throttle. An intake portion of the air intake channel expands conically toward an upstream side. An air guide tube is aligned co-axially and radially outward from a fuel feed tube forming an air passageway there between. The intake air portion flows through the air passage from the intake portion of the air intake channel and into a bottom space of the cylindrical chamber beneath the rotary throttle.

Abstract: A method of illuminating an object with a waveguide system includes directing a beam of light into a waveguide. The waveguide includes a light input region, a front lenslet array having individual lenslets with a radius of curvature, and a rear surface. The beam of light directed into the waveguide is reflected off of the front lenslet array. A portion of the beam of light passes to the rear surface so that the portion leaks out of the waveguide. The portion that leaks out is reflected laterally through the waveguide by an external reflector.

Abstract: An electronic compass is described for use in vehicles. The compass employs a magnetoresistive sensor for sensing the earth magnetic field and the sensor is operated in alternate set/reset bias modes. In a first embodiment, the compass is provided with deviation compensation by a closed loop system including measurement of the sensor output signals and an offset current strap for nullifying the vehicle deviation field. In a second embodiment, deviation compensation is provided by operation in an initial calibration mode and by operation in a normal compensation mode to adjust compensation, as needed, on a long term basis during normal operation of the compass. In the initial calibration mode, while the vehicle is being driven, the signal peak values are adjusted to a nominal earth field level by changing the offset current. Then, compensating signal reference values for each axis are determined as each peak for that axis is determined.

Abstract: A two stroke combustion engine, equipped with fuel injection apparatus and ignition timing controlled by throttle position, has a charge forming device which delivers a rich fuel mixture from an integral float-type fuel chamber. The fuel injection apparatus typically comprises a tuned injector tube that communicates between a crankcase injector port and a cylinder injector port. The vast majority of fuel mixes with air in an injector mixing passage of the charge forming device where it is subsequently delivered to the tuned injector tube which directly injects the rich fuel mixture into a cylinder of the engine. The rich fuel mixture supplied by the charge forming device injects into the combustion chamber through the cylinder injector port via a reflected pressure wave generated from the previous combustion cycle.

Abstract: A bending and hemming apparatus configured to both bend and hem a sheet metal panel to form a body closure member at a single station. The apparatus includes a hemming machine movable between a retracted position spaced from a bending machine and advanced positions adjacent the bending machine to assist in the bending operation and to hem the body panel into a finished product. The apparatus also includes an anvil assembly pivotably supported on the hemming machine. The anvil assembly is movable between a lowered position where it engages the workpiece when the hemming machine is advanced to a bending position adjacent the bending machine. In the lowered position, the anvil assembly provides a fulcrum around which the workpiece is bent. The anvil assembly is pivotable to a raised position to allow the hemming machine to be advanced to a hemming position adjacent the bending machine from which the hemming machine can engage the bent workpiece to hem the workpiece.

A safety latch is provided to avoid inadvertent removal of the support body from the chamber of the housing.

Abstract: A fuel injection system for a two-stroke small engine has a charge forming device with an injector mixing passage which forms a rich fuel and air mixture supplied to a tuned injector tube connected adjacent one end through a port to the engine cylinder and adjacent the other end to the engine crankcase. The charge forming device has a high speed fuel circuit which supplies at least a majority of the fuel to the mixing passage under wide open throttle operating conditions and preferably a minor portion of the fuel is also supplied by an idle fuel circuit which under engine idle conditions preferably supplies essentially all of the fuel to the engine. A separate inlet air flow passage of the charge forming device also supplies primarily air to the crankcase of the engine for transfer to the cylinder.

Abstract: A parison handling device has a pair of opposed arms with each arm having at least a pair of grippers to selectively engage an extruded parison and transfer it to a second location such as to a mold of a blow molding machine. At least one gripper on each arm is both slidably and generally pivotally movable relative to the arm to facilitate initially engaging and gripping the parison and subsequent closing and stretching of a gripped end of the parison to more efficiently distribute the material of the parison such that after blow molding of the parison, the molded product has a substantially uniform wall thickness throughout. Preferably, a follower attached to each movable gripper is responsive to a profile or contour of a cam carried by each arm to guide the movement of the gripper corresponding to the profile of the cam.

Abstract: Apparatus for molding blocks with laterally projecting, undercut side features includes a mold box having split mold parts defining a mold cavity open at the top and bottom. A top plate overlies the mold parts and is formed with an opening aligned with a cavity. Moldable block material is charged into the cavity from a feed box, and the material is compacted and shaped between a lower pallet and upper stripper head which are moved to close the bottom and top of the cavity during vibration of the mold. The mold parts are retractable beneath the top plate to release the block for stripping through the bottom of a mold. A plurality of fluid outlets in the top plate communicate with problem areas of the recessed mold parts which are prone to accumulate residual block material. Pressurized clean-out fluid, such as air is directed through the outlets onto such problem areas to cleanse the mold surfaces of the block material between mold cycles.
