The containment space for the scrap is increased by this wall arrangement and provides an impetus in the bunker for scrap flow to an underlying scrap delivery chute. The scrap delivery chute is formed by an elongated scrap carrying trough having a greater width than the exit width of the scrap holding bunker for delivering scrap to a charging opining for an electric arc furnace A superstructure supporting the scrap holding bunker at an elevated and lateral spaced location from the electric arc furnace. A ram controlled by a drive incrementally advances scrap along the scrap delivery chute for introducing successive preselected volumes of scrap to a charging opining for an electric arc furnace.

Abstract: A high temperature bolting system for clamping steam turbine housings and similar high temperature parts together while operating at a temperature of 800° F. to 1200° F. An elongated fastener shank and housing material have similar coefficient of thermal expansion. The shank has a tensile strength several times greater than the housing to maintain a clamping force during thermal excursions. The diameter of the shank is reduced due to the large creep strength difference between the elongated fastener shank and the clamped parts. The reduced shank diameter allows an increased in the clamping load by providing an increased surface area in the clamped part. A stress generating flange is provided with jackbolts to establish the clamping load at room temperature. A threaded sleeve is interposed between the threads at the end of the shank and the threads of the housing so that the housing threads have a sufficiently large area for withstanding the clamping load.

Abstract: A hand-held tool for forming a rivet head at the plain end of a rivet includes an elongated handle having an elongated internal cavity with a guide wall surface extending to an adjacent guide wall surface in an insert having an end wall. The end wall is provided with a predetermined thickness and contains an aperture to house a shop head formed on the plain head of a rivet. An inertia block is slidably guided by the guide wall surfaces of the handle and insert for reciprocation between a displaced position remote from the end wall and a position for contact with the end wall. A spring located in the elongated handle urges the inertia block against an end of a rivet when protruding from the aperture in the end wall and arrests recoiling movement of the inertia block after impact with a rivet end in a direction away from the end wall.

Abstract: Jackbolts for multi jackbolt tensioner embody a thread construction which taper from a maximum diameter adjacent to torque receiving end of the jackbolt when threadedly engaged with a threaded opening in the outer peripheral part of a jackbolt body. The threads of the jackbolt have a different thread pitch than the threads in the jackbolt body and the tooth flank of the jackbolt threads for an angle with the tooth flanks of the thread in the jackbolt body. By this thread construction, there is formed a helical volume of ever increasing size along the jackbolts commencing at a metal to metal relation at the torque receiving end. Stressing of the jackbolt closes the helical volume bringing the threads to a metal to metal load transfer relation. The end of the jackbolts has a protruding central end portion that elastically flattens under stress to reduce torque requirements.

Abstract: Workpiece rotators are constructed for decoration registration control in spaced apart decoration stations for bottles rotatably supported by carriers of an endless chain conveyor. A screen drive at each decorating station linearly reciprocates a decorating screen to decorate the bottle. A squeegee is positioned to maintain line contact between the decorating screen and a bottle for applying decoration during each screening cycle. The workpiece rotator is coupled by a drive controller to the screen drive to rotate a bottle synchronously with linear travel of the decorating screen. The drive controller uncouples the workpiece rotator from the screen drive at times other than the application of decoration to a bottle.
