Abstract: A valve seat for ball valves comprises a ring-shaped or annular body fabricated of sintered metal particles having interparticulate spaces which are substantially completely filled with graphite. The seat is fabricated by pumping a dispersion of colloidal graphite in a liquid carrier through the matrix of a preformed ring-shaped sintered metal body, thereafter heating the body to drive off any portion of the liquid carrier which remains in the interparticulate spaces of the body, and then coining the body to collapse any voids which remain in the body and to mechanically bind into the body the graphite which has been trapped in said interparticulate spaces during the pumping step.

Abstract: An unlatching tool to uncouple the trailer from the tractor of semi-trailer truck rigs, comprising a foldable elongated bar having a hand grasp at one end and a combination safety release arm plus unlatching hook at the opposite working end. The safety release arm extends at a right angle from the working end of the bar and in one direction from the bar, while the unlatching hook extends outwardly from the bar in the opposite direction and set back from the working end a short distance. When the unlatching hook engages the coupling latch which locks the king pin of the trailer to the tractor, the safety release arm extends forward of the unlatching hook just far enough to bear against the safety release mechanism which can be moved to the safety release position by a partial rotation or twist of the bar while at the same time pulling on the bar to draw the coupling latch to the unlatched position. The trailer can then be uncoupled from the tractor.

The lining can be used down to the rim ends at each pad while the pad center still contains lining where the molding holes are located.

Abstract: Components such as lids (9) and electronic chip carriers (10) are assembled by registering respective mating faces of each component. An array of assembly stations (75) are formed on an upwardly extending edge (67) of a base (66) having a special inclination. For example, a lid (9) is supported with its mating face upturned and a carrier (10) is supported with its mating face downturned upon the upturned face of the lid (9) on the base (66). The inclination causes the components to slide relative to each other and the base in a given direction within each station (75). A plate (92) overlies a plate (72), supported on and inclined with the base (66). Plate (72) has an opening (74) and plate (92) has an overlying opening (94) to each station (75). The openings (74) and (94) have respective reference edges for stopping sliding of, and thereby positioning an upturned lid (9) and a downturned carrier ( 10) thereupon with a desired registration.

Abstract: Apparatus for measuring or monitoring the diameter of rod-shaped workpieces comprises two driven and interdigitating pinion rollers for rotating the workpiece about its longitudinal axis and at least one pair of mutually opposite measuring gages adapted to be urged against the workpiece and connected to an electronic evaluating device. To permit a rapid measurement of the workpieces which is independent of the attention and carefulness of an operator, the workpiece is fed via an inclined trough to the pinion rollers so that the workpiece engages an axial stop. The workpiece is then urged against the pinion rolls by a pressure-applying roller, which is radially movable into and out of engagement with the workpiece. By spring force and/or a pressure fluid the measuring gages are jointly moved into and out of engagement with the workpiece when the latter lies on the pinion rolls and is axially located by the axial stop.

The straightedge is made substantially thicker than required for structural strength, to enhance the offset appearance of lines viewed through the prism and thus increase sensitivity of offset indication. The straightedge preferably has two edges on opposite sides and parallel with each other.

Abstract: An apparatus for stunning animals and which has multiple propulsive charges. The apparatus is of the type in which a spike or plunger is projected toward the head of an animal to be slaughtered. The barrel of the apparatus is mounted on a part pivoted to the breech for pivotal movement about an axis parallel to the axis of the barrel.
