摘要： Forming a vacuum-tight fused bundle of light-conducting fibers in a compression mold. An elongated mold having a cross cavity with a plunger closing each of the four sides thereof is filled with light-conducting fibers extending along the length of the cavity in side-by-side parallel relationship with each other. The fibers are heated to fusing temperature and the plungers are all simultaneously forced against the fibers toward a central axis through the cavity under uniform high pressure whereby a substantially uniform pattern of individual fiber distortion is produced throughout the resulting fused bundle of fibers.

摘要： A cathode-ray tube for electro-optically reading a moving manuscript. The tube includes a long and thin strip of juxtaposed light-conducting fibers extending through its face with corresponding opposite ends of the fibers disposed internally and externally of the tube envelope. Internal ends of the fibers are coated with a light sensitive electron-emissive material which is surrounded by a layer of electroluminous material. A manuscript moved across the strip of light-conducting fibers externally of the tube is read by scanning the coating of electroluminous material along the length of the strip of fibers with an electron beam produced within the tube. Light from the luminous layer, in passing through the tube face, illuminates the manuscript along the outer face of the strip of light-conducting fibers and light reflected from the manuscript in amounts characterized by the subject matter to be read therefrom is transmitted back into the tube by the strip of light-conducting fibers. The light sensitive electron-emissive material at the innermost ends of the fibers emits a pattern of electrons corresponding to the pattern of intensities of light received thereby. These electrons are collected by a target within the tube and produce an electrical charge in the target which may be used as an electrical reading signal per se or converted into other forms of reading information.

摘要： A cathode-ray tube is provided with a light-transmitting face comprised of a rectangular strip of optical fibers having a long and narrow light-emitting end across which a manuscript is moved for photoelectrically copying subject matter thereon. A flying spot of light produced within the tube is transmitted through the strip of fibers onto the manuscript and portions of this light reflected from the manuscript are received by a prism-lens system adjacent the emitting end of the strip of fibers. This system then directs the reflected light onto a photoelectric transducer for conversion into an electrical signal which is useful as an electrical reading of the manuscript or convertible into other forms of facsimile information.

摘要： PLASTIC LIGHT-CONDUCTING FIBER RIBBONS ARE FORMED OF A TRANSPARENT HIGH REFRACTIVE INDEX STRIP OF PLASTIC MATERIAL COVERED WITH THIN FILMS OF RELATIVELY LOW REFRACTIVE INDEX PLASTIC MATERIAL. THE COVERED STRIP IS HEATED AND ROLLED TO THE CONFIGURATION OF A MULTIPLICITY OF INTERCONNECTED JUXTAPOSED FIBERS FROM WHICH MONOFILAMENTS MAY BE CUT LONGITUDINALLY OF THE RIBBON.

摘要： Producing bundles of optical fiber by winding successive layers of the fiber in the same spiral direction on winding apparatus. The apparatus includes a main winding drum over which a second coaxially aligned hollow drum of larger diameter is moveable along the common axis of the drums. A motor-driven lead screw coupled to the hollow drum is actuable to move the hollow drum back and forth along the winding surface of the main drum from one end to the other thereof while both drums are rotated by a common drive shaft. With the hollow drum positioned at one end of the main drum, the fiber is wound from the opposite end of the main drum along its surface up to and onto the hollow drum. Without interruption of the winding process, the fiber is returned to the beginning of the winding surface of the main drum by moving the hollow drum up to the starting point of the first winding. The hollow drum is then retracted causing the fiber to engage the first fiber winding on the main drum and continue therealong in the same spiral direction. A guide roller moved back and forth parallel to the common axis of the drums controls the pitch of spiral winding.
