Abstract: A machine and method for subdividing into individual substrates a wafer which is prescored with a pattern of intersecting score lines defining the substrates. The wafer is progressively directed over a first wafer-engaging surface substantially paralleling one set of score lines, and this surface cooperates during a breaking operation to impart a localized force at a score line in the set.

Abstract: An apparatus is disclosed for breaking apart, pre-scribed chips in a semiconductor wafer. The apparatus comprises a plurality of ball elements having a diameter substantially smaller than the diameter of the wafer, mounted in a support beneath the contacting plane.

Abstract: A tube separator has two blocks with vertically and linearly aligned protrusions to which joined tubes are attached for separation into individual tubes. The protrusions are interdigitally arranged when the blocks are adjacent each other. A chain drive engages one block and pulls it from the other block which is locked in a fixed position. A guiding means maintains the blocks in an upright position. An ejecting means for separating the tubes from the protrusions engages the driven block and ejects the tubes from the protrusions. The fixed block is pushed by a driven block from a succeeding cycle and also engages the ejecting means for removing the tubes from the protrusions. The chain drive returns a block along the guide means so that an operator may reuse them with other tubes.

Abstract: The pre-grooved plates e.g. of chewing gum are advanced over a stationary breaker edge into the path of a rotating, polygonal (preferably triangular) breaker shaft whose apices form breaker edges which rotate past the stationary breaker edge. Each facet of the shaft is provided with a stop positioned to be engaged by the leading edge of the advancing plate. The distance across a facet from the respective stop to the respective rotating breaker edge is equal to the width of a strip to be broken from the plate at the next groove in the plate. The axis of rotation of the breaker shaft is transversally displaced from the level of the plate, by an amount sufficient to provide the rotating breaker edge, at the site where the breaking occurs, a velocity component in the direction of advance of the plate which approximately matches the velocity of advance of the plate. Accordingly, the advance and rotary breaking may proceed continuously.

Abstract: There is provided a process for recovering block shaped graphite fuel elements made of a graphite block with a parallel cooling channel and which block contains the fuel arranged in separate zones. The process is especially useful for such fuel elements in which the cooling channels and the fuel zones are distributed in a screenlike manner adjacent to each other and wherein these fuel elements are first comminuted mechanically and then are reconditioned by burning and wet chemical separation into fissile material and waste material. For the mechanical comminution of the graphite block conical pins (or mandrels) are simultaneously pressed into several cooling channels until the block is broken apart along the entire length of these cooling channels.

Abstract: A pair of endless moving link chains have respective spans which are disposed in opposed relationship and driven in the same direction. One of the pair of the link chains carries thereon outwardly projecting blank holding pins at intervals along the length of the chain, while the other link chain carries thereon outwardly projecting sheet product pushing out pins. The spans of the link chains are disposed in converging relationship with respect to the moving direction of the spans. A blank comprising at least one sheet having cut lines defining a sheet product is supplied into the space between the spans at the upstream end of the space with respect to the moving direction. As the blank is conveyed between the spans the sheet product pushing out pins move transversely relative to and toward the blank holding pins because of the convergence of the spans and finally push out the sheet product from the remaining part of the blank which is being held by the blank holding pins.
