Abstract: Method and apparatus for making certain types of parts which are stepped in one plane and curved in other planes transverse to the planes in which they are stepped. The invention uses a specially shaped billet which is formed into the part in a closed flashless die set at warm forging temperatures.

Abstract: A clip is provided for use in the suspension filing of magazines, journals and like articles having sheets or pages held together in a spinal portion. The clip comprises a bifurcate part having two fingers engageable respectively inside and outside the spinal portion of a magazine to grip the spinal portion between them, and a hook part engageable over a side rail of a suspension filing system. By inserting a clip at each end of the spinal portion of a magazine and engaging the hooks over the two parallel rails of a suspension filing system, the magazine can be suspended with its spinal portion performing the function of the normal cross-bar in such a system.

Abstract: A segmented female die for use in a closed die set comprising a pair of similar center segments and a pair of similar "half moon" shaped outside segments. The four segments also define the ejector pin opening. The die segments are prevented from relative motion between themselves by interlocks comprising closely mating protrusions and guideways which, in cooperation with other means, produce a rigid female die. The interlocks permit the use of relatively simple manufacturing techniques such as grinding as opposed to more sophisticated techniques such as electrical discharge machining.
