Abstract: A machine for straightening anode rods has a portal-like frame through which the rods are transported in succession with the aid of a suspended rail conveyor. Jaws which engage on the sides of the rods are used to squeeze the rods. Beneath the jaws there is a rotatable fork which can engage and entrain with a shaped end piece on the lower end of one of the anode rods. The fork and its rotary drive is raised and lowered and guided for this reciprocal movement. An anode rod can thus be transposed through 90.degree. enabling the jaws to squeeze against all the sides of the rod.

Abstract: A pivotal connection between a handle and a housing, where the handle includes a cylindrical opening, and the housing includes a pair of cylindrical openings on opposite sides of the housing and concentric with the handle opening. A sleeve with a central tubular opening is disposed within the housing and handle openings, and has an outer diameter substantially equal to the diameter of the housing and handle openings. A cylindrical pin has an outer diameter greater than the inner diameter of the sleeve tubular opening and is wedged into the sleeve tubular opening to bulge the sleeve outwardly into beveled portions of the handle opening. The connection is formed by first aligning the handle between housing portions so that openings therethrough are disposed substantially concentric to one another. Then, a tubular sleeve is located within the housing and handle openings. Finally, a pin having an outer diameter greater than the inner diameter of the tubular sleeve opening is wedged into the sleeve opening.

Abstract: A door dampening assembly for dampening the swinging motion of a vehicle door includes a timing plate, a mounting bracket, and an expandable and contractible link connected to and between the timing plate and the mounting bracket. Operator access doors on construction vehicles can cause damage to the door hinge, the door frame, or the door itself, if left unrestrained during swinging movement of the doors from an open position to a closed position. The subject dampening assembly allows the vehicle door to swing freely from a fully open position to a partially open position. The timing plate and the expandable and retractable link decelerate the door to a partially open positon, thereby preventing any damage to the door or other vehicle components.

A mechanism is provided for fixing the container relative to the movable crosspiece during extrusion so that auxiliary jacks, provided for moving the container independently of the crosspiece, can be used during extrusion to assist the main jack.

Abstract: A vehicle-repair apparatus has a floor-mounted generally rectangular track having two long and two short sides that are spaced apart sufficiently to accept a vehicle within the sides. A long portal having a pair of upright leg members and a cross member spans the track between the short sides and a similar short portal spans it between the long sides. These portals can be moved perpendicularly to each other along the respective sides. It is possible to lock each of the legs at the respective side to the track, and to lock the cross members of the portals together. A support can be secured to any of the legs or cross members and a jack in turn can be secured to it to pull or push out a dent in a vehicle standing within the track.

Abstract: An extrusion die mounted in a die holder is fitted onto the end of the press stem of an extrusion press by apparatus which has a swing arm which receives a die holder in a first position, then pivots to a second position where the die holder is aligned with the extrusion press stem, rotates the die holder so that it is correctly oriented relative to the press stem and then pushes the die holder axially onto the press stem.

Abstract: In order to prevent heat loss by conduction from the billet and billet container in an indirect extrusion press, the sealing plate, which closes off one end of the billet container bore, is made in two parts which are spaced apart when an extrusion stroke is not taking place so that an air gap appears between the two parts to interrupt the path of heat conduction through the sealing plate to the rest of the extrusion press. The air gap may be produced in the pressure plate, between the sealing plate and the moving cross-head, instead of or in addition to the gap in the sealing plate.

Abstract: A process and device for carrying out the process allows for the extrustion of composite sections comprising a beam-like section made of a light metal and at least one insert made of another metal which provides a facing on at least one surface of the beam-like section. The beam-like section, which may be a conductor rail, is produced by extruding through a shape-giving die whereby at least two composite sections are produced simultaneously and the facing strips are positioned pairwise between opposite lying parts of the beam-like sections. The present invention allows the facing strips to be introduced into the extrusion device without the extreme bending previously experienced. Brittle materials which could not withstand the extreme bending experienced heretofore can now be used for facing material.

Abstract: A process and device allows long as-cast billets to be extruded, with the help of a container which is divided into at least two segments which can be opened and closed radially with respect to the main axis. In the closed position, the segments grip the part of the billet inside the container and, as a result of a relative movement between a die mounted on a hollow stem, the said die is forced into a length of the billet inside the container as a result of which at least one section is extruded. On opening the segments, the billet is advanced to fill the container again whereupon the segments close, clamping onto the billet, and the extrusion sequence is repeated.

Abstract: In tube extrusion presses, there are two steps in production. Firstly, a mandrel pierces a hole through the center of a billet, the tip of the mandrel ending up just within the opening of the extrusion die. Secondly, the now hollow cylindrical billet is extruded through the die and over and around the tip of the mandrel to produce a tube. To limit the movement of the mandrel, stroke-limiting rods are provided which pass through bores in a part attached to the mandrel and in a fixed part of the press. The rods can be held fast in one or both of these bores, or released to slide through them, depending on the stage reached in the extrusion process.

Abstract: A cyclically operable machine having a work station where a blank is deformed into a work product and in which the work product is ejected on to a conveyor oscillated between that station and another conveyor to which the work product is delivered synchronously.

Abstract: An alignment system for non-adjustable motor vehicle front end suspensions, such as those employing McPherson struts, has a support assembly anchorable relative to an adjacent vehicle being repaired, with a connector arrangement provided on the support assembly for permitting one of the struts to be restrained relative to the support assembly while the other of the struts is being pulled into proper position. Once the struts have been correctly positioned in accordance with factory specifications, the sheet metal forming the fender wells, and the like, can be welded or bolted in place while pressure is maintained on the struts so as to re-unitize the vehicle body portions with which the suspension system is employed.

Abstract: Disclosed is a mandrel for a high pressure tube extrusion press. The mandrel comprises a tip member providing a tip adapted to be positioned in the die opening of the press to present an annular gap for tube extrusion, and a carrier for the tip member. The carrier has a threaded central tip member receiving bore for threadably receiving a threaded segment of the tip member therein. A divided ring shaped element is disposed between a flange on the tip member and the carrier in an annular space provided at the mouth of the bore to facilitate the assembly and disassembly of the mandrel and prevent inadvertent separation of the tip member from the carrier.
