Abstract: A retention pin assembly may include a stud having a head, a shaft, and a deformable end. The shaft may include a stepped surface having a greater diameter than the deformable end. The assembly may include a support member having an opening for receiving the deformable end. The support member may include a pocket. The stepped surface of the shaft may position the stud in relation to the support member. The deformable end of the stud may be operable to be melted to form a mechanical retainer within the pocket without forming a metallurgical joint between the stud and the pocket.

Abstract: A ball joint structure according to an exemplary embodiment of the present invention includes: a ball stud having a ball formed at one end thereof; a bearing including a first bearing coupled to the ball providing an interior surface thereof to slide on an exterior surface of the ball and covering a portion of the exterior surface of one side of the ball, and a second bearing coupled to the ball providing an interior surface thereof to slide on a portion of the exterior surface of the ball and covering an exterior surface of another side of the ball; and a ball housing which is insert-molded together with the bearing to cover the outside of the bearing.

Abstract: An integrated throttle body for an electronic fuel injection (“EFI”) system and its method of manufacture. The integrated throttle body of the invention comprises a molded throttle body housing in which the throttle valve, shaft, bore and motor housing are all molded in a single shot from a suitable thermosetting resin or thixomolded from magnesium.

Abstract: The present invention relates to a color cathode ray tube provided with a pressed-type shadow mask. As material for constituting the shadow mask 6, a single plate body made of a composite gradient alloy plate consisting of three layers 6A, 6B, 6C or more in which an alloy element has the concentration gradient which is continuously changed from one surface to the other surface is used. The present invention can realize a pressed mask having a large radius of curvature by self-correcting the thermal deformation such as a doming or the like.

Abstract: The invention relates to a bimetallic casting serving as a wear piece in vertical mills and its method of manufacture. It includes a core (13) made of a ductile cast iron and provided with mechanical bonding elements in the form of pins (15) which are rendered integral with an outer casing (17) by casting, the outer casing being made of a non-ductile wear material having a high chromium content. Such castings are used for being mounted on the hub of a roller of a so-called vertical-axis crushing mill.

Abstract: Chain forming dies having inner surfaces shaped to form a desired number of linked chain elements. The dies are adapted to close against one another and a casting gate to each chain element forming section is provided. The connection for the chain elements are formed by a die insert inserted in a groove between each chain element forming section. The die insert simultaneously forms holes on extrusions of each chain element and axial posts on the mating end of each adjacent chain forming element. Means are provided to position the die insert when the chain forming dies are closed against each other. Mating coupler elements are formed by coupler-shaped sections in the chain forming dies.

Abstract: A locking pulley assembly includes a pulley adapted to be affixed to a surface, a pull handle, a swivel hook, and a cord extending between the swivel hook and the handle around the pulley wheel. The pulley includes a unitary pulley wheel having locking grooves and coaxial frustoconical bearing surfaces, the pulley wheel being mounted for rotation in a unitary frame having inwardly facing frustoconical bearing surfaces engaging the bearing surfaces of the pulley wheel to form a rotatable joint. The handle is comprised of a cylindrical member having a central axial hole with reduced diameter at its central portion for holding a knotted end of the cord. The handle also has a slot at each end thereof of width slightly less than the diameter of the cord, to enable the handle to hold the cord. The swivel hook has a first element adapted to be affixed to the other end of the cord, and a hook pivotally mounted on the first member.
