Abstract: A method of forming a ball screw member from an elongated workpiece having an outer cylindrical surface, as well as the ball screw member formed by the method. A helical ball screw thread is machined on the outer cylindrical surface, the helical ball screw thread having a helical groove and a helical crest surface. An end journal or other end treatment is formed in the workpiece, the end journal or other end treatment being located during the forming operation relative to the helical crest surface. The outer cylindrical surface of the workpiece may be centerless ground prior to the machining of the helical ball screw thread. The helical crest surface may be ground after the machining of the helical ball screw thread to provide increased concentricity between components of the ball screw member. A high precision ball screw member may be formed from the ball screw member by performing a regrinding operation on the helical groove, the regrinding operation being positioned relative to the helical crest surface.

Abstract: The pieces to be palletized are conveyed by a roller table to bar elements which reciprocally turn the pieces so that they face each other. Grippers then grip the facing pieces which originally lie flat, so as to move them into a vertical parallel position on a conveyor belt. An upper conveyor belt engages the top of the vertical parallel pieces to hold them in correct orientation. An automatic strapping mechanism them applies this strap around the pieces. A roller table is provided for lateral movement of the strapped packages. The roller table which initially receives the pieces pass in a horizontal flat position on the roller table. A section of the roller table has portions of its rollers removed so that undersized pieces fall through the opening thus formed. Only pieces with correct size, that is, unbroken pieces, are conveyed along the parallel passages of the roller table.

Abstract: A method and apparatus for staking a formable projection, for example, a tab or boss, to retain plural articles in a unitary assembly. A projection on a first article is brought into registering position with an aperture in a second article to form the assembly. The assembly is clamped by a spring-loaded clamp pad which bears against the second article and surrounds the projection. The projection is then staked by action of a tool which travels reciprocally within the clamp pad and has a tip which cooperates with the clamp pad to form a cavity of desired shape. The forming stroke of the tool is against the resistive force of the spring, which increases the clamping force of the clamp pad. The formed projection is therefore contained within the inner boundary of the clamp pad and tool tip to thereby promote uniform head formation.

Abstract: A slider applicator has a stopper attached to an end of a slide rod slidably mounted in a pivotable casing for movement parallel to a feed path along which a slide fastener chain is fed through a slider supported on a slider holder. When the stopper is displaced for a prescribed distance by box and insertion pins on the slide fastener chain, a microswitch is actuated to operate an air cylinder for angularly moving the casing to lift the casing out of engagement with the box and insertion pins, which are now allowed to move with the slide fastener chain past the stopper. In the event of improper positioning of one of the box and insertion pins, adjacent endmost coupling elements are jammed in a slider to thereby prevent the stopper from being displaced for the prescribed distance. A sensor switch is then actuated to signal such improper positioning of one of the box and insertion pins.

Abstract: A mounting arrangement for a windscreen glass is shown. Around the top and sides of the windscreen opening, a rubber section is mounted on a bodywork flanged joint, the rubber having embedded in it a metal carrier which has an extension which emerges outside the plastics to provide an exposed stiff metal lip which partially embraces a recess holding mastic. The section of the mounting arrangement along the bottom of the windscreen opening differs in that its metal carrier does not have such extension or the exposed metal lip, and the plastics immediately beneath the recess has a slot into which a stiffening member can be clipped. The windscreen is mounted in position by sliding it upwardly in to the sides and top of the windscreen opening. The glass is thus trapped in position behind the exposed metal lip and sealed and adhesively secured by the mastic.
