Abstract: CATHODE RAY TUBE PRINTING APPARATUS AND METHOD                ABSTRACT           Apparatus is described for producing hard copy prints of images displayed on a raster-scanned CRT terminal.  A row of light-fibres are attached to a preselected scan line of the CRT.  The other ends of the row of light fibres are located along the surface of a print roller on which light sensitive paper is supported.  A light pattern pro-duced as a result of an image scan along the preselected scan line is transmitted by the light fibres to the paper which is exposed to form a latent image of the light pattern in a print row on the paper.  In order to print a complete image, the paper is drawn past the print row and exposed successively to each raster scan row of the image to be printed.  The exposed paper is then passed through a developing station where the latent image is developed by heat.  Two modes of operation are described.  In one mode the image display is interrupted during the print cycle, in the other mode both display and printing are performed concurrently.

Abstract: Abstract of the Disclosure A method is disclosed for producing book covers, a folder, a booklet or the like consisting of a blank with at least Gne cover and a spine connect thereto via at least one crease line and a bonding agent or binder for adhering pages or the like inserted in the book covers, folder, booklet or the llke to the inside of the spine.  The binder is placed in the form of a strip on a base so that both longitudinal side edges of the strip are oriented between two creasing elements projecting above the surface of the base, and the blank is aligned into a predetermined position above the base and creasing elements. A press presses the blank against the creasing elements and strip to form the crease lines and to attach the strip to the inside of the spine.  An apparatus for carrying out the method comprises a base for the strip, creasing elements for orienting the strip, and a press.  In an alternative embodiment of the invention, the strip is cut from a roll or sheet of material by a cutter which also serves as a base for the strip while the latter is pressed into adherence against the inside of the spine of the blank, which has been provided with the crease lines during a previous work operation.

Abstract: ABSTRACT           The invention relates to an electrostatic copying apparatus of the type in which an electrostatic latent image is formed on the surface of a photosensitive member.  Specifically, a corona discharge device is used to charge up the photosensitive member and an image of an original document is projected to the charged surface by an optical system including a lamp for illuminating the original thereby to form the electrostatic latent image.  According to the invention, for a specified period of time which runs from the time when the corona discharge device for charging has been deenergized by the completion of the electrostatic latent image-forming step light is irradiated on the surface of the photosensitive member in an area downstream of the corona discharge device for charging and upstream of the developing device along the moving path of the surface of the photosensitive member.

Abstract: HOT SPRUE ASSEMBLY FOR AN INJECTION MOLDING MACHINE                 ABSTRACT OF THE DISCLOSURE           A hot sprue assembly is provided for control-ling flow of molten material into the mold cavity of an injection molding machine.   The hot sprue assembly is particularly designed for use with an injection molding machine for molding  centrally apertured record discs, such as video information discs.  The hot sprue assembly includes a hot sprue bushing cooperating with a disper-sion head  to define  an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc.  Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during solidification of the material within the mold  cavity,  permits the material  within  the mold cavity to solidify up to the gate without substantial solidification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the solidified disc to prevent any surface discontinuities  arising  by retraction  of  the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.
