Abstract: ABSTRACT OF THE DISCLOSURE       The disclosure relates to a label on a closured bottle, including a pilfer-proof feature.  The neck label comprises a secondary closure in the form of a sleeve of a shrinkable oriented thermoplastic material shrunken snugly over the bottle and its closure skirt.  The label stock is preprinted in a web and rolled as a supply, the roll width representing the label height.  The label stock is (1) scored a partial depth of its thickness extending lengthwise along a line that is at a predetermined height in the final label and (2) pleated transversely at spaced intervals therealong.  The pleats are spaced so that a predetermined number thereof appear in each label blank cut from the stock.  Label blanks are cut to length, wound to an annular sleeve shape so that the trailing end of the blank overlaps the leading end and the overlapped ends united at an axial seam.  The sleeves are placed over the neck and closure skirt of a closured bottle such that the score line of weakening in the material is adjacent the lower edge of the closure skirt.  Heat is applied to shrink the label into snug surface engagement with the underlying surfaces.          The pleats, especially on smaller sizes of ware, avoid wrinkles in the shrunken label and enhance a smooth appearance thereof.          Preferably, the pleating in the label comprises at least a pair of pleats disposed on opposite sides and near the axial seam.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for repairing windshields and the method for using the apparatus wherein a liquid, curable resin material is forced into cracks in the windshield, using an apparatus mounted directly to the windshield, and which provides a high injection pressure and subse-quently a vacuum so that the crack is completely filled, and air bubbles are removed from the filling resin during the time the resin cures.  The apparatus in one form includes a disposable, simple-to-make injector that seals positively around the opening of the crack so that the resin is forced into place, and by reversing the injector, a suitable vacuum can be applied to the injected resin for removal of air bubbles.

Abstract: Improvements in or relating to Visual Display Apparatus Abstract The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators.  The apparatus provides binocular vision of a display projected onto the inside of a part-spherical shell which surrounds the pilot and carries a concave retro-reflective screen.  The display covers an area of interest determined by craft position and attitude and the viewer's instantaneous line of view.  The image or images are projected from points horizontally in line but vertically displaced above the viewer's eye positions.  If the retro-reflective screen material has a very small angle cone of reflection, light is reflected back to the projection point rather than to the viewer's eyes.  The invention provides a screen reflection characteristic modified in all vertical planes by the use of an optical grating in combination with a highly retro-reflective screen material.

Abstract: ABSTRACT            Method and apparatus for imaging charged electrophotographic member by electrostatic techniques using information which is derived from a source of binary data.  The binary data may be achieved by imaging a pattern or may he synthesized electrically to represent that which it is desired to reproduce on the electrophotographic member.          The binary data is applied to a pixel generator which is constructed and arranged to produce an output in the form of signals for driving an electro-optical deflector that in turn deflects a laser beam to form a composite of rays.  The composite of rays represent the columns of a pattern to be applied to each pixel which is generated, the rows of the pixel being produced by a shaft encoder that is synchronized with the rotation of a cylinder carrying the electrophotographic member.  The pixel generator produces hexagonal pixels and the pattern in each pixel represents density information derived from the binary data originally received by the pixel generator.  The patterns in the pixels are arranged to prevent undesirable moire effects.  The invention is embodied in a digital laser printing plate maker wherein an electrophotographic member receives the composite laser beam from a carriage which moves in synchronism with the rotation  of the cylinder and the rate at which the composite beam is applied.  The resulting latent image is toned and fused on the cylinder.  After certain processing, namely, hydrophillizing of the non-imaged areas, a plate suitable for printing is formed.

Abstract: ABSTRACT            A method of replicating data from a master transmissive optical data storage medium whereby the resulting pro-duct displays areas of low reflectivity and high re-flectivity.  Actinic radiation is shone through trans-missive areas onto a silver-halide emulsion photo-sensitive medium.  The photosensitive medium is then chemically developed black.  Next, the developed medium is fogged to create a latent image layer of silver pre-cipitating nuclei.  Finally, the fogged medium is placed in a monobath comprising a weak silver-halide reducing agent and a rapid-acting silver-halide solvent for partial chemical development and substantial physical development.  The resulting product displays areas of low reflectivity, which correspond to the transmissive areas of the master, in a reflective field.

Abstract: (59-8) ABSTRACT           A belt tensioning device for an endless drive belt for a vehicle accessories drive system.  A bracket, which terminates in a pair of outwardly extending end flanges, is adapted to be mounted on a vehicle engine adjacent the drive belt.  A cylindri-cal cup-shaped housing is mounted on each of the bracket flanges and contains a pair of volute springs.  A plunger is operatively engaged by each of the volute spring pairs and is biased out-wardly from an open end of the housing toward the oppositely mounted spring housing.  The axes of the plungers are parallel to each other and spaced apart.  A lever is pivotally mounted on the bracket intermediate the spring housings and extends from the bracket perpendicularly with respect to the axes of the plungers.  The plungers are connected to the lever, one on each side of the lever pivot point.  An idler puller is rotatably mounted on the extended end of the lever and is moved in a belt tensioning direction for engagement with the drive belt by the biasing actions of the volute springs.  The volute springs pro-vide and maintain a generally constant tensioning force on the drive belt, and also provide a damping effect due to the unequal load rate deflection of each spring coil and due to the sliding friction between the individual spring coils.

Abstract: SERIAL ENCODING-DECODING  FOR CYCLIC BLOCK CODES          Abstract of the Disclosure Means for serially encoding and decoding cyclic block codes having minimal parity check bits and single error correcting capability are disclosed.  Encoder comprises: serial shift and divide means for generating parity check bits to append to the data word and thereby form the channel word; input buffer for storing bits of the next channel word during evaluation of the parity bits of the previous word; and output buffer registers for storing bits of the channel word for eventual transmission. Certain registers are partitioned into a parallel arrange-ment of register segments of predetermined lengths so as to effect full loading of each segmented register prior to the request for transmission from each register.  Decoder comprises: means for shifting and dividing the received word to generate the syndrome as well as iteratively shifted versions of the syndrome; means, alternating operation with the shifting and dividing means, for comparing the characteristic polynomial of the code with the iteratively shifted versions of the syndrome; and means for correcting, in response to a predetermined output from the comparing means, the received word by inverting the bit in the received word depending on the number of iterations performed in generating the iteratively shifted versions of the syndrome.  The decoder comprises two substantially identical sections each having two modes of operations.  The sections alternate modes of operation so that two contiguous blocks are processed during a given interval.
