Abstract: A thermoplastic bag structure comprising a front and rear bag wall, a bottom and an open mouth top portion, said open mouth portion being characterized by having two pairs of single film handle loops each of which are located at opposite ends of said open mouth portion, the handles of each pair being side-by-side and each handle is an integral single film loop extension of said front and rear bag walls. The bag structures can be unitized by providing a detachable tab at the bag mouth opening and unitizing the bag structures through this tab. The method of forming said bags involves providing an end sealed collapsed thermoplastic film tube and removing plastic to form a bag mouth opening and handles at one end thereof.

Abstract: A photosensitive member having at least two electrically operative layers. The first layer comprises a photoconductive layer which is capable of photogenerating and injecting photo-excited holes into a contiguous active layer. The active layer comprises a transparent organic material which is substantially non-absorbing in the spectral region of intended use, but which is "active" in that it allows injection of photo-excited holes from the photoconductive layer, and allows these holes to be transported through the active layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light, and development.
