Abstract: A camera system for the simultaneous and substantially exact capturing of images of a subject on separate image reproduction mediums wherein an optical member is interposed between a lens group and a pair of separate, discrete image receiving mediums. One of the mediums is a photographic film and the other is a viewing screen for personal viewing or, alternatively, an electronic system for electronic signal generation, electronic viewing and electronic capture of the image. The optical member allows light rays emanating from the object to pass therethrough to impinge upon one of the mediums while simultaneously reflecting light rays to the second medium. This system allows for the simultaneous transfer and reproduction of the object image onto more than one medium without degradation of the image or depth of field. The system accomplishes the multiple image transfer through a stationary device, thereby eliminating the necessity of moving parts.

Abstract: The feedthrough device includes first and second half housing members, each of which has an internal chamber. The feedthrough device further includes a removable header member that fits within the chambers of the first and second half housing members when they are threaded together. The first half housing member has a threaded protrusion which fits into a threaded aperture located in the wall of a sealed structure, such as the wall of a vacuum furnace. The threaded protrusion arrangement includes a first "O" ring which seals the periphery of the aperture in the wall of the sealed structure. The header has first connectable terminals on one end and second connectable terminals on the other end. In between the first and second connectable terminals of the header there is located a plate member which fits along the edge of the first half housing member chamber; and located between that edge and the plate is a second "O" ring.

Abstract: A light beam scanning device and method comprises a first input source for providing a scanning light beam and a flat stationary scanning surface to be scanned by the beam. An f sine theta lens system focuses the light beam onto the flat stationary scanning surface. A galvanometer mirror provides for repetitively scanning the light beam across the flat stationary scanning surface in a first fast scan direction while a pivoting mirror provides for receiving the light beam and scanning it onto the galvanometer mirror in a second slow scan direction perpendicular to the first direction. The cooperative operation of the galvanometer mirror and the pivoting mirror raster scan the light beam onto the flat stationary scanning surface.

Abstract: A scanning device for causing a beam of light to be repetitively swept across a surface includes a laser source for providing a beam of laser light and a pentaprism assembly which redirects the beam of light to the surface. The pentaprism assembly includes a support member and a plurality of pentaprism elements positioned around the periphery of the support member. An arrangement is provided for rotating the support member such that successive ones of the plurality of pentaprism elements are brought into the path of the beam of light and redirect the beam of light to the surface. Movement of each pentaprism element while intersecting the beam of light causes the beam of light to sweep across the surface. The scanning device may also be used without a laser source to scan ambient light which is reflected from a surface and direct the light to a detector.

Abstract: Stereoisomerically pure forms of normorphine analogs which have superior analgesic and nonaddicting qualities are described. In addition, a method of separating diastereomeric forms of N-sec-alkyl-substituted analogs utilizes the hydrocarbyl(1-8C) diesters of the normorphine derivatives. A new method for preparing the N-methylalkylmethyl derivatives of normorphine and norcodeine and their conventional analogs is also disclosed. This method employs the corresponding methyl alkyl ketones and a reducing agent.

Abstract: A unitary magnification lens system for an electrophotographic imaging system including a folded optical system is made of synthetic resin. It has an f/5.6 aperture for increased light gathering power to ease the requirements of the imaging system illumination system and a moderately wide field angle of 64.degree. to image documents of up to 81/2.times.14 inches at a time. The lens system is non-vignetting and includes aspherical surfaces on its four elements, arranged in two pairs, that deviate to as much as the tenth order from the conic.

Abstract: Graphics and text data are combined selectively to discharge incremental areas of a charged electrophotographic member to form thereon a latent text and/or graphics image represented by the graphics and text data, the imaged member thereafter being toned and output from the system so that the toned image may be fused on the member and the member may be used as a printing plate in an offset lithographic printing press. The apparatus includes an optical system that may form a maximum of 22 individual rays which are deflected twice through a field flattening lens and then onto the charged member. The optical system further includes an optical scale or grating which provides electrical signals indicating the precise location of the individual rays along scan lines on the member. The apparatus further includes an electronic system which generates electrical signals from the graphics and text data to form the 22 individual rays.

Abstract: A flat bed scanner system for optically sensing a transparent original image and producing three channels of binary digital data representing the densities of the original image. Each channel produces data in response to one sensing color and sensing of the original image occurs by directing a focused image of a beam of white light onto and across the original image in a pattern of parallel scan lines there being a plurality of sensing positions along each scan line, and producing the digital output data in response to the modulated beam of light transmitted by the original image. There is an optical system which provides for the directing of the beam of white light across the original image and which directs the modulated beam onto sensors. The optical system includes color correction and field flattening of the beam of white light and provides a cylinder condenser lens for the modulated beam of white light.
