Title: Apparatus for singularizing stacked dielectric  receptor sheets for latent images
Inventor: KROEBEL HEINZ
IPC: G03G15/00

Abstract: 1950-87a ABSTRACT OF THE DISCLOSURE      Apparatus for feeding dielectric receptor sheets and/or sheet-like carriers for receptor sheets to the ionography imaging chamber of a radiographic system from a nearly upright stack of overlapping sheets has a set of suction heads which are mounted on a first lever pivotally mounted on a second lever.  The first lever is repeatedly pivoted relative to the second lever to thereby move the suction heads, which attract a portion of the outermost sheet of the stack below the upper edge face of such sheet, along an arcuate path to thereby flex the upper part of the outermost sheet away from the neighboring sheet.  The second lever is thereupon pivoted to complete the separation of the outermost sheet from the neighboring sheet and to introduce the upper edge face of the separated outermost sheet into the nip of two advancing rolls which transport the sheet toward or into the interelectrode gap of the imaging chamber.       A stripping device is adjustably mounted in the path of movement of outermost sheets with the suction heads relative to the second lever to flex such sheets between the suction heads and the respective upper edge faces whereby the outermost sheets are even more likely to become separated from the neighboring sheets.  A pivotable lever is provided to maintain the stripping device in such position that the latter is located at a fixed distance from the paths of upper edge faces of successive outermost sheets, irrespective of changes in the thickness of the stack.

Abstract: ABSTRACT          This invention relates to a belt conveyor comprising a convey-ing belt suspended in a plurality of suspension points in a stand, which belt includes energy-absorbing elements and a flex-ible belt portion located therebetween and has the object to bring about such a belt conveyor, which renders it possible to transport therewith goods not only in an open but also in a closed way. This object is achieved by the present invention substantially in that rollers are arranged in the conveyor stand to co-operate with the energy-absorbing elements and to carry the belt in an endless path, in which the belt is driven by driv-ing rollers arranged in the stand, and the energy-absorbing ele-ments are designed with the same section as a V-belt, while every roller co-operating with such a V-belt section of the belt ex-tends with its axle substantially in parallel with that side of the V-belt section, to which the roller abuts with its running surface, and every driving roller for driving the belt includes at least one V-belt groove for driving engagement with one of the V-belt sections of the belt, which is held in this driving engagement by means of at least one pressing roller.

Thin wall tubes consisting of one of the metallic elements of the alloy material, or an alloy of such element are provided.  If an alloy tube is selected, all elements in the tube alloy must also be materials included in the over-all formulation of the alloy material.  The type and quantity of the materials contained in the tubes is deducted from the quantities set forth in the over-all formula and the balance of the formula is melted and poured as a core in the tube using the tube as a mold.  The resulting master charge is cut into unit charges each of a predetermined weight.  These unit charges are then used in a subsequent casting operation by melting the entire unit charge to cast precision products of an alloy which consists of the mixed and alloyed materials of both the tube and the core.
