Abstract: A mounting plate for an attachment with an insertable plug type tubular connector and a process for making the plate. The mounting plate comprises a sheet metal plate having length, width and body thickness T with a tubular nipple member projecting from one side. The nipple member is cold formed plastically from the body of the plate by a stamping process utilizing a progressive die. One of the intermediate die members is shaped such that it produces a tubular preform having a distal end portion with a wall thickness greater than the wall thickness of the opposite end portion adjacent to the plate. A subsequent die member reduces the excess wall thickness and extends the tubular member to an axial length equivalent to at least 3T measured from the distal end of the neck member to the surface on the opposite side of said plate. Subsequently, another die member precisely finishes a feature located in close proximity to the nipple member.

Abstract: A bale spike frame for lifting and carrying bales weighing 2,000 pounds or more. The frame members are tied together and reinforced at strategic locations by an integrating plate. The frame is a welded assembly made basically of tubular steel stock having a square cross section and also of some steel plate stock. It has elongated tubular top and bottom members joined to shorter length plate members at their ends to form a rectangular frame. A main bale spike mounting socket is provided in the top frame member and two tubular inserts are provided in the lower frame member for attaching bale stabilizing spikes. An intermediate frame member located directly below the socket extends perpendicularly between the top and bottom frame members and is butt welded thereto. Peripherally welded integrating plates extend from below the bottom end of the intermediate frame member over its front and rear faces and onto the top surface of the top frame member.

Abstract: A gas fired melting apparatus for particulate material. The melting apparatus has four successively connected vertically disposed sidewall members, a floor member and a roof member. These members define a cubic melting chamber for containing a freestanding generally conical pile of particulate material to be melted. The sizes, shapes and positions of the chamber radiating surfaces as well as their relative distances from the pile surfaces promote heat transfer to the pile. A high temperature gas fired burner is mounted in each sidewall adjacent to the corner formed by the tail end of one sidewall and the head end of a successive sidewall member. The axis of each burner is parallel with its successive wall member so the combined effect of the burners is to produce a toroidal flow of combustion products in the melting chamber around its central vertical axis.

Abstract: An injection molded fuel injection rail for an automotive engine. The fuel rail is designed to supply fuel to a plurality of electromagnetic fuel injectors oriented at acute angles relative to vertical. The socket inlet apertures through which fuel is fed from the rail interior into the respective fuel injector sockets are located in the bottom of the rail. This prevents the ingestion of vapor, which is normally present in the upper portion of the rail, into the injectors. In order to maintain both sides of these socket inlet apertures at substantially the same level the tilted injector sockets are provided with an occlusive lip along the high side of each inlet aperture. Additionally, the tilted socket axes may be offset laterally downward from the longitidinal rail axis. A plug type fitment is used to close the barrel core pin opening at one end of the rail.

Abstract: An apparatus for atomizing a gasoline-alcohol blend of automotive fuel and supplying a supplemental amount of vaporized fuel to the intake ports of an engine during cold weather start-up. Also a method of making the same. The apparatus comprises a tubular member having a plurality of configured atomizing orifices. It is positioned inside an engine air intake manifold with its orifice facing away from the intake port side of the manifold in an upstream direction. The orifices are formed by a stamping process wherein a die deforms the tube inwardly at each orifice site and ultimately punctures the tube wall producing a "T" shaped orifice opening with burred irregular edges and contoured sides. Preferably, each of the apertures is located between a pair of intake ports. Fuel is supplied to a head end of the tubular member, such as by means of an electromagnetic fuel injector, and the tail end of the member is closed.

Abstract: A fuel rail assembly for distributing fuel to a plurality of electromagnetic fuel injectors which in turn supply atomized fuel to the cylinders of an internal combustion engine. Each of the injectors has a fuel inlet section that is removably held in an injector socket in the rail. Inside the rail a filter member, having a relatively large surface area, is provided at each injector socket to filter only that porton of the fuel which flows into its respective socket immediately prior to the entry of the fuel into the socket. The injector sockets and the filter members are designed so they have mating cylindrical sections which allow the filter members to be telescoped over the corresponding cylindrical sections of the sockets. Each filter member has a dome section which covers a fuel inlet aperture in the socket. The dome section extends from the cylindrical section into an open space above it where the apex of the dome abuts another member of the rail assembly thereby holding the filter member in place.

Abstract: Adjustable fitments for attaching any one of a variety of implements to the ends of the lifting and tilting arms of a tractor of the type normally used with front end loaders.

Abstract: A package for holding frangible particulate material, such as breakfast cereal. The package is designed to separate the crumbs or fines from the larger or unbroken and more palatable particles of cereal and to trap the crumbs so they will not recombine with the more edible portion of the cereal when the container is upended to pour the cereal into a bowl. The package has a partition member insert comprised of an apertured screening section and at least one imperforate ramp section inclined towards the screening section. The screening and ramp sections are supported above the bottom of the container to provide for sifting of the crumbs through the screening section, while the package is in its normal upright position, and to allow the crumbs to gravitate into the trapping space, defined by the imperforate ramp section, the bottom closure and the surrounding walls, when the package is tilted during pouring.

Abstract: A liquid fuel fired apparatus and method for the efficient distribution and utilization of heat in the melting of a particulate feedstock. The feedstock is preheated to an incipient softening point temperature in a vertically disposed shaft. The column of feedstock in the shaft is supported on the top of a freestanding pile of feedstock disposed on the floor of a surrounding melting chamber having downwardly diverging sidewalls. Liquid fuel burners direct hot combustion products towards and around the base and intermediate portions of the feedstock pile causing the outside of the pile to be melted. Gas at a temperature below the softening point temperature of the feedstock is introduced around the top of the pile to prevent the hot gases in the lower portion of the melting chamber from prematurely melting the feedstock.

Abstract: An improved limited slip differential gear assembly for driving each axle of a pair of coaxially aligned vehicle axles at the same rotational speed or at relatively different rotational speeds as conditions require. The assembly includes an improved externally controllable clutch mechanism for preventing excessive relative rotation of the axles. The amount of the clutch force being applied to resist relative rotation may be varied independently of the relative rotational speed of the axles and also of the torque level in the gear assembly. Preferably the clutch mechanism is incorporated in a planetary wheel type differential and is activated electromagnetically. The clutch mechanism may include a cam operated supplemental clutch device for applying an additional clutch force in response to any continued relative rotation which may occur after the first clutching force has been applied by the electromagnet.

Abstract: A mechanism and method for operating a device for crimping a metal outer sleeve of a hose connector around the end of a flexible hose. The device has a constrictor collet assembly for radially inwardly deforming the sleeve in response to axial movement of the collet assembly in a frusto conical die ring. Axial movement is imparted by a ram and a pair of pusher members mounted between the ram face and the collet assembly. The pusher members are swung between open and closed positions by the operating mechanism which has a pair of lever arms connected to the pusher members at one end and to a pintle at the other end. The pintle is slidably mounted for lateral movement in a slot.

Abstract: A low inertia springless check valve suitable for operation at high frequencies in a hot environment against a high cyclic back pressure with a relatively constant low input pressure, such as in an automotive engine exhaust air induction system. The valve has a circular elastomeric diaphragm mounted on a supporting frame by means of a retainer disk, a fastener and a diaphragm limiter. A central portion of the diaphragm is compressed between the disk and limiter to cause the originally flat diaphragm to become dished and biased towards the valve seat. The limiter is designed to stabilize, in the flow direction, a portion of the diaphragm extending along the entire length of an adjacent diameter of the diaphragm. The retainer disk also functions in part as a diaphragm motion limiter in the check direction.
