Abstract: A magnetic brush development apparatus for applying pigmented marking particles to a latent image charge pattern on a dielectric member (D). The magnetic brush development apparatus comprises a housing (12) defining, in a portion thereof, a sump (12a) for containing a mixture of magnetic carrier particles and pigmented marking particles. A mixer is located in the sump of the housing for mixing magnetic carrier particles and pigmented marking particles so as to effect a triboelectric attraction of the pigmented marking particles to the magnetic carrier particles. The mixed magnetic carrier particles and attracted pigmented marking particles are attracted to an intermediate member (16), transported by the intermediate member from the sump, and then separated by the intermediate member such that the magnetic carrier particles are returned to the sump. A magnetic brush development roller (22) including a magnetic core (24) and a shell (26) rotatable relative to one another, has the shell coated with a prescribed layer (L) of magnetic carrier particles and an electrical bias applied to the shell. The marking particles are attracted from the intermediate member to the magnetic brush and then transferred to a latent image charge pattern on the dielectric member to develop such pattern.

Abstract: A high aperture finite conjugate lens system has a high numerical aperture on both object and image sides of the lens system. The lens system comprises an aperture stop located approximately as the center of the system and a plurality of lens elements centered on an optical axis and arranged into two lens groups of positive power to provide the high numerical apertures on both the object and the image sides of the lens system. The two lens groups are located on each side of the aperture stop and each lens group comprises an outer-most lens element and an inner-most lens element. The inner lens elements are located in close proximity to the aperture stop and each of the inner-most lens elements have a convex surface facing towards the aperture stop. It is also an object of the invention to provide a printer, for example, a laser thermal printer, using such a lens system.

Abstract: Disclosed is an improved process for the preparation of phenylhydroquinone wherein hydroquinone is first alkylated with cyclohexene to produce cyclohexylhydroquinone which is then dehydrogenated to obtain phenylhydroquinone. The improvement comprises carrying out both the alkylation and dehydrogenation reactions in the presence of a solvent comprising diphenyl ether, biphenyl or a mixture thereof. The solvent possesses selective solubility for hydroquinone and cyclohexylhydroquinone which permits the separation of unreacted hydroquinone from the alkylation reaction product. The boiling point of the solvent also permits the dehydrogenation reaction to be performed at substantially atmospheric pressure.

Abstract: A photoelectrographic element for electrostatic imaging, containing a conductive layer and a photosensitive layer, is produced using photosensitive layer materials which form a barrier to charge injection where exposed to near-infrared radiation. As a result, exposed areas can be charged, while unexposed portions cannot. The photosensitive layer contains an organic photoconductor, a near-infrared radiation sensitizer, and, optionally, an organic binder. A method of forming images with this photoelectrographic element is also disclosed.
