Abstract: A loose packing material for the muffler of an internal combustion engine is confined by a mesh, for handling the loose packing as a unit during assembly of the muffler. The openwork nature of the mesh is such that the mesh does not affect the sound or tune of the muffler, such that the original sound of the muffler is the same as its long term sound. The mesh can comprise fiberglass or metal mesh, but preferably includes a heat consumable material such as a thermoplastic polymer. The mesh can be formed as a wholly or partly closed bag with a shape complementary to a muffler cavity, which can be irregular. The heat consumable type of bag is formed by heat sealed seams. The mesh holds the loose packing material clear of peripheral seams or internal points at which structural parts of the muffler are intended to abut. The confined packing and its methods are particularly apt for stamped plate mufflers and are likewise applicable to other forms such as rolled casing and extruded casing muffler structures.

Abstract: A loose fiber packing material for a muffler of an internal combustion engine is temporarily confined in a transfer cartridge, having a shape which is substantially complementary or somewhat smaller than the muffler cavity. The transfer cartridge is adapted to receive a pushing device for discharging the loose fiber packing material from the transfer cartridge into the muffler cavity during manufacture of the muffler. The transfer cartridge allows loose fiber packing to be prepacked, shipped and directly transferred to a muffler cavity without the use of molding resins or packaging materials which would otherwise be inserted into the muffler along with the loose fiber packing material and burned away during initial use of the muffler, causing undesirable smoke and odor.

Abstract: A lightweight body for a dump truck includes a floor with a pair of opposed spaced upwardly extending side walls coupled thereto. An upwardly extending front wall is included and coupled to the floor between the side walls to thereby create a space for carrying a payload and a rearward spillway for dumping the payload. The floor is formed of a plurality of adjacently positioned sections that are either separate pieces or form part of one continuous piece. The sections are arranged in an order of increasing thickness or hardness with the thickest or hardest section located at the spillway. This body structure substantially reduces weight while simultaneously preserving body strength, thereby allowing dump truck payload capability to be increased.

Abstract: A truck includes a chassis with a body movably mounted to the chassis behind a cab. The body is movable between a first position generally parallel to the chassis and a second generally upright position with respect to the chassis. A canopy is movably mounted to the body. The canopy is movable between an extended position and a retracted position. In the extended position, the canopy extends outwardly from the body to cover the cab when said body is in the first position. The canopy is retractable to decrease the overall height of the truck when the body is in the generally upright second position.

Abstract: Apparatus for stance improvement includes an aperture which may have optical sight therein, located in the grip or shaft of a golf club so that the ground or light is visible to the player when the club is properly aligned, the player's feet, knees, hips, and shoulders are properly located; and the player's head is in the correct position to hit a straight golf shot with an iron or fairway wood on which the golfer's downward line of sight intersects the club grip or shaft. The aperture is positioned at the point of intersection between the club grip or shaft and the line of sight. Several such apertures may be formed in the shaft and/or grip to assist the golfer in addressing the ball for different golf shots, such as a straight shot or a draw or a fade.

Abstract: A molded fiberglass product and process for producing that product are disclosed. A fiberglass mat is molded to a desired shape. It is trimmed and placed between two sheets of facing fabric, the facing fabric pretreated with a thermoset binder and a heat activated adhesive. The facing sheets and fiberglass mat are placed into a press with a heated mold where the fiberglass is compressed at its edges and the sheets are sealed to the fiberglass and beyond the fiberglass edges to each other. The resultant workpiece is trimmed and the final product is a completely enveloped molded fiberglass product with all fiberglass surfaces and edges, both external and internal, enveloped in facing, no fiberglass exposed.
