Abstract: An electroluminescent device (10, ... 60) comprises an electroluminescent layer (11, ... 61) together with a p-type silicon layer (13,... 63) and an n-type silicon layer (14,... 64). The layers (11,13,14,... 61,63,64) constitute a heterojunction or transistor-like structure which limits the total device current during operation. This avoids current runaway experienced in prior art devices, and has been found to extend operating life. The electroluminescent layer (21,31,41) may be in contact with a transition metal oxide layer (25,35,45) to provide self-healing of pinholes. The electroluminescent device (30) may include additional p-type and n-type silicon layers (36 and 37) to provide a degree of current control. The p-type silicon layer (43,53,63) may be connected to an ohmic contact (48,58,68) for control of device current. The silicon layers (13,14,... 63,64,36,37) are either crystalline or amorphous.

Abstract: A document sheet feeding and registration apparatus and method is described for deskewing and registering a document sheet (7) relative to a registered copying position on a copier platen (3) by feeding it against a sheet aligning document registration stop (18). Initially the document sheet is fed towards the registration stop (18) with a first document sheet feeder (17) exemplified by a widely transversely spaced pair of high friction sheet feeding rollers, which resist skewing of the document sheet. Then the first document sheet feeder (17) is removed from the document sheet (7) after its lead edge is engaged by a second document sheet feeder (16) and before the document sheet (7) engages the registration edge stop (18) so that final skewing control of the document sheet is only by the second document sheet feeder (16). The second document sheet feeder (16) is a single sheet feeding roller positioned centrally of the document sheet lead edge area and positioned closely adjacent the registration edge (18). This single roller provides a brief low rotational resistance deskewing of the document sheet (7) while driving the document sheet into final alignment with the registration stop (18). All of the sheet feeding rollers are positioned over the document on the platen extending through a backing plate (27) so as to be hidden during copying.

Abstract: The present invention is directed to a method and apparatus for providing raw edge protection on the edge (12) of a paper laminate (10) such as a polyethylene-paper- polyethylene-aluminum foil-polyethylene laminate (14, 16, 18,20,22). Such laminates are useful in forming paperboard containers for foodstuffs or other products which are to be protected against the entry of moisture, bacteria, or other contaminants. According to the method and apparatus of this invention, a laser beam is employed to burn away the exposed edge of the paperboard layer of the laminate as it moves relative to the laser beam. After removal of a strip of the paperboard from an edge of the laminate, the remaining areas of the laminate (40, 42) are pressed together and sealed as by the application of heat. In a modified method, a polyethylene powder stream, or a polyethylene filament, is continuously melted and flows over the remaining edge (44) of the paperboard, to thus seal it. The invention may be applied to a continuous web or single blank of the paper laminate.

Abstract: A method and an apparatus are described for processing and applying a protective foil to a flat sheet made, more particularly of a thermoplastic synthetic material. The protective foil is used to protect the relatively soft surface of the sheet but, during further processing, difficulties arise in that parts of the surface must be freed of protective foil. In order to protect at least certain areas of the sheet as long as possible from external effects or damage, there is provided a protective foil which, before it is applied to the sheet or to a strip from which the sheet is subsequently produced, is formed with perforations. During further processing of the sheet, the parts of the foil corresponding to the areas of the sheet that are to be freed, are removed and the remainder is protected by the remaining parts of the protective foil.
