Abstract: Apparatus for supporting a primary automotive door panel and door trim panel during a manufacturing process includes at least one rest block. The rest block has a rocker provided with first and second arms extending radially outwardly from a pivot axis at an angle to one another and perpendicular to the pivot axis such that adjacent surfaces of the arms form a radially outwardly opening recess. The rocker is supported for pivotal movement from a loading position in which the recess opens laterally to a work-supporting position in which the recess opens upwardly. The inner surfaces of the arm meet adjacent to the pivot axis to define a notch adapted to support a lower edge portion of the primary door panel when the rocker is in the work-supporting position. One of the arms has a shelf adapted to support the trim panel when the rocker is in the work-supporting position. The other arm carries a roller made of a soft, non-abrasive material such as rubber or plastic.

Abstract: A nozzle setting jig useful for aligning and holding a nozzle in proper orientation in an upwardly positioned opening in a sidewall of a pipe or round vessel for welding the nozzle thereto. The jig is useful for use with standard nozzles which nozzles include a short cylindrical section with a flange attached to one end while the other end is contoured cut to coincide with the curvature of a sidewall of a pipe or vessel to which the nozzle will be attached. The nozzle setting jig includes a nozzle flange mounting plate with two length adjustably legs which are self centering and which are adaptable for use with numerous size nozzles. The jig allows a welder to set the proper depth of the nozzle within the opening in the pipe or vessel while also aligning the heavy nozzle both laterally and archingly in relation to the longitudinal axis of the pipe or vessel to which the nozzle will be attached.

Abstract: A quick clamping type vice in which a chuck and a spring are disposed in a main base seat. The chuck is substantially U-shaped and an inner side of the bottom of the chuck is formed with a semicircular thread facing upward. A cover board is disposed on the upper side of the chuck and locked with the chuck to form an integral body. The spring is disposed right under the chuck. The thread rod passes through the main base seat and ride on the bottom of the chuck. The spring pushed the chuck upward to make the thread of the chuck engaged with the thread rod. When the cover board is depressed, the chuck is vertically moved downward and disengaged from the thread rod. At this time, the thread rod is liberated and can be quickly slided. When releasing the cover board, the spring makes the thread of the chuck again engaged with the thread rod. Accordingly, the clamping and loosening operation of the vice can be quickly performed.

Abstract: A pair of pliers includes a body, a movable handle, a movable jaw, a push block, and a pull element. The movable handle and the movable jaw are both connected pivotally to the body so that they can displace about an angle. When the movable handle turns in the direction of the body, it can bring the push block to displace therewith so that a U-shaped end push portion of the push block press against a curved rack portion at the bottom face of the lower portion of the movable jaw, causing the curved jaw teeth of the movable jaw to close in the direction of a fixed jaw. And when the movable handle and the end push portion disengage from the front acting teeth of the curved rack portion, they can press against the rear acting teeth of the curved rack portion to clamp pipes of a larger contact surface. When the movable handle is turned outwardly away from the fixed handle, the pull element is utilized to cause the movable jaw to pull and turn quickly to a desired angle.

Abstract: A wafer polishing apparatus includes one or more wafer carriers each containing one or more wafers mounted on both sides of the carrier. Upper and lower turntables having upper and lower polishing surfaces, rotate to polish the wafers attached to the carriers. Hence, wafers on the top of the carriers, and wafers on the bottom of the carriers are polished simultaneously. This configuration increases throughput; also, thermal deformations in the wafers are reduced, thus improving flatness.

Abstract: A vehicle jack of the type known as "Y-jacks". It has a base plate (1) with perforated fins that receive and fix, in a particular way, the protruding necks on the wings of the jack body. A nut (13) is secured to the end of the body, with easy entrance into the end and fixed by some lugs (14) which are bent over the central portion of the nut. The arm (3) of jack also has two protruding necks towards the interior, on which a cross member is received, formed by a part with a U-shaped section whose wings or sides clasp on to the necks, are made with U-shaped openings. The base of the cross member is controlled by a special easy entrance holder plate on the housing on the arm. An arm (30) of a specially designed shape acts in combination with a holder plate-cross member, whose seating for the vehicle has a metal insert. This holder plate-cross member is provided with an external retainer on which the end of the screw spindle is supported.

Abstract: A closed loop wire saw loop, a method for making the closed wire saw loop, and an apparatus and method for slicing a work piece, in particular, a polysilicon or single crystal silicon ingot, utilizing a closed loop of diamond impregnated wire in which the work piece (or ingot) is rotated about its longitudinal axis as the diamond wire is driven orthogonally to it and advanced from a position adjoining the outer diameter ("OD") of the ingot towards its inner diameter ("ID"). In this manner, the diamond wire cuts through the work piece at a substantially tangential point to the circumference of the cut instead of through up to the entire diameter of the piece and single crystal silicon ingots of 300 mm to 400 mm or more may be sliced into wafers relatively quickly, with minimal `kerf` loss and less extensive follow-on lapping operations. The closed wire saw loop is made by squaring and welding the wire ends together and then twice heat treating the weld at about 1500 F.

The threaded rod is extended through the bores of the plurality of clamp members such that the clamp members are rotatable about the longitudinal axis of the threaded rod. An end cap is coupled against rotation to one of the ends of the threaded rod.

Abstract: A small vehicle lift of the parallelogram type is described wherein parallel pivoting legs are pivotally attached at their opposing ends to a base and a support platform, whereby the lift ranges from a lowered state wherein the support platform is in close parallel relation to the base and a raised position wherein the support platform is in spaced parallel relation to the base. Both the support platform and the base pivotally bear the legs within channels and thereby surround the legs at opposing planes adjacent the planes wherein the legs pivot. The channels within the base also have wheels rotatably mounted therein to allow the lift to be easily transported. Two opposing pivoting legs are affixed together by a bridge member which is pivotally connected to a linear actuator, which is in turn pivotally connected to the base. Actuation of the linear actuator thereby raises and lowers the support platform with respect to the base.

Abstract: A jack includes a base member having a first chamber in which a piston is received, a main cylinder connected to base member and having a tube extending therein to which the lifting piston is movably mounted, a casing mounted to the main cylinder so as to define a second chamber between the casing and the main cylinder. A first path connects the second chamber and the first chamber and a second path connects the first chamber and the tube so that fluid enters into the tube to extend the lifting piston by operating the piston. A protection path extends between the outside of the base member and the second path with a first branch path and a second branch path respectively extending from the protection path and connecting the second chamber and the interior of the main cylinder. The pressure in the tube can be released by unscrewing the bolt threadedly engaged with the protection path so as to let the fluid enter into the second chamber and the interior of the main cylinder.
