Abstract:
A photosensitive member having a binder layer comprising photoconductive particles dispersed in an electrically insulating active organic matrix material. The photoconductor comprises a material which exhibits the capability of photo-excited hole generation and injection, with the active organic matrix being substantially transparent and nonabsorbing in the wavelength region of use and capable of supporting the injection and transport of photo-excited holes from the photoconductive particles. The member may be imaged in the conventional zerographic mode which includes charging, exposure to light, followed by development.
Abstract:
A welded web comprising a first edge of a web having at least one aperture overlapping a second edge of a web comprising thermoplastic material on an exposed surface along the second edge to form a region of contiguous contact between the first edge and the second edge, at least a portion of the thermoplastic material at least partially filling the aperture thereby bonding the first edge to the second edge. The web may be formed by a process comprising providing a web having a first edge, providing a web having a second edge, forming at least one aperture in at least the first edge, overlapping the first edge over the thermoplastic material on the exposed surface along the second edge whereby the thermoplastic material on the second edge at least covers the aperture to form a region of contiguous contact between the first edge and the second edge, raising the temperature at least in the region of contiguous contact adjacent the aperture whereby thermoplastic material from the second edge at least partially fills the aperture thereby bonding the first edge to the second edge.

Abstract:
METHOD OF FABRICATING COMPOSITE TRIGONAL SELENIUM PHOTORECEPTOR A method of making a photosensitive imaging device which comprises; vacuum evaporating a thin layer of vitreous selenium onto a supporting substrate, forming a relatively thicker layer of electrically active organic material over said selenium layer, followed by heating said device to an elevated temperature for a time sufficient to convert the vitreous selenium to the crystalline trigonal form. The imaging device is also disclosed.

1470459 Vinyl substituted polycyclic aromatic compounds XEROX CORP 25 June 1974 [27 June 1973] 28048/74 Heading C5E [Also in Divisions C2 C3 and G2] Vinyl substituted polycyclic aromatic compounds of the formula Q-CH = CH 2 (where Q is a polycyclic aromatic group having at least 3 fused ring nuclei) are prepared by contacting an aldehyde Q-CHO with a phosphine ylide Y 3 P=CH#-#Y 3 P + -CH 2 - (where Y is alkyl, phenyl or alkylphenyl). Examples of Q are 1,2- benzanthracene; 1,2,5,6-dibenzanthracene; 1- methyl - 2,3 - benzocrysene; 2,3 - benzocrysene; 3,4-benzopyrene and a crysene group. The reaction may be carried out at 20-85‹ C.
