Abstract: L'invention concerne une capsule de bouchage inviolable pour des bouteilles comportant un bourrelet extérieur au voisinage de leur goulot, cette capsule comprenant un opercule en matière plastique muni d'un plateau destiné à s'appliquer sur la face d'extrémité du goulot et d'une partie d'étanchéité en saillie vers le bas sur ledit plateau et destinée à être enfoncée à force dans le goulot pour coopérer avec la surface intérieure de ce dernier, et des moyens déchirables coopérant, avant la première ouverture de la bouteille à boucher, avec le bourrelet du goulot pour retenir l'opercule de façon inviolable sur le goulot. La capsule de bouchage selon l'invention est caractérisée par le fait que le bord extérieur supérieur du plateau est surélevé par rapport à la partie du plateau destinée à s'appliquer la face d'extrémité du goulot de bouteille et que les moyens déchirables sont constitués par une bande de garantie annulaire réalisée d'une seul pièce avec l'opercule, prolongeant la paroi latérale extérieure du plateau de l'opercule vers le bas. Cette bande de garantie présente un bourrelet intérieur d'accrochage au bourrelet du goulot et comporte une languette s'étendant vers le haut jusqu'à hauteur du bord extérieur supérieur du plateau en constituant un secteur de la paroi latérale extérieure du plateau. La bande de garantie est reliée au bord extérieur inférieur du plateau de l'opercule par une ligne de moindre de résistance et la languette est reliée à la paroi latérale extérieure du plateau de l'opercule par deux lignes de moindre résistance dont l'une est prolongée vers le bas à travers la bande de garantie. L'invention s'applique aux bouteilles à bague, notamment à bague à gorge, et assure une inviolabilité parfaite tout en éliminant les risques d'ouverture intempestive, par exemple lors de la manutention des bouteilles.

Abstract: ABSTRACT          A high lubricity codeposit of zinc and graphite, and an improved method for depositing the codeposit, is disclosed.  The coating is characterized by a coefficient of friction equal to or less than .130, and a high resi-stance to corrosion evidenced by no red rust in a salt spray environment for 72 hours and no destruction due to corrosion in an industrial environment, containing sulphur dioxide, for four months.  When the codeposit additionally has a chromate outer coating, the system has a coefficient of friction equal to or less than .112 and has no red rust in a salt spray environment for at least 120 hours.  The codeposit is applied by immersing a cleansed metallic substrate in an acidic zinc plating electrolyte containing at least 40 g/l zinc ions and 30-110 g/1 insoluble bulk graphite, with a pH of 5-5.7.  The cell of which the electrolyte is a part is energized to plate out a co-deposit; the graphite is continuously agitated while in solution, the agitation being periodically interrupted to allow the graphite to settle and saturate the zinc inter-face as it is plating out.

Abstract: ABSTRACT OF THE DISCLOSURE         A system for counting videotape cassette play includes a counter sealed within the cassette to count plays.          A count signal is provided on the tape or a movable part of the cassette.  Coded access circuitry allows retrieval of the count.  Discrimination circuitry discriminates between a count signal passing an internal head at the slowed play speed, as opposed to the fast-forward and rewind speeds.  A rental agent's unit is a decoder that is programmed with the correct digital code word that permits access to the count stored in the cassette's circuitry.  A decoding and display circuit converts the count to a visible numeric display for the rental agent.  Resetting the cassette's counter is pro-hibited except in the presence of the digital code word.          The count signal can be electromagnetically recorded at a frequency distinct from the audio and video content, can be an opening or transparency optically detectable, can be a reflective segment optically detectable, or a conductive segment bridging contacts that engage the tape.  Frequency and duration of the signal provide means to recognize the signal passing the pickup at play speed.  Certain embodiments of the system provide further information such as tape source, rental rate, or title.  This information is contained in the count signal or in separate memory.

Abstract: Abstract This invention relates to infrared transparency films and films for thermal imaging processes, and in particular, to a coating material for such films.         Infrared imaging involves the use of a focused infrared lamp to heat an infrared absorbing image, i.e., the "original", which is in contact with a substrate, e.g., a transparency film, having thermally sensitive imaging chemicals.  Upon absorbing the focused infrared light, the infrared absorbing image heats the thermally sensitive imaging chemicals on the substrate, causing a chemical reaction, resulting in a copy of the original image on the substrate.         When projection transparencies are prepared from originals which are plain paper copies prepared from electrophotographic imaging processes, localized heating of the original results in partial remelting of the toner powder thereon, causing the original to adhere to the transparency.  When the original is separated from the transparency, toner powder from the original is transferred to the transparency film, resulting in partial destruction of the original and irregular black spots on the transparency.         This invention provides thermally imageable film comprising a polymeric substrate, a layer of thermally imageable material coated over at least one major  surface thereof, and a release coating coated over the layer of thermally imageable material.  The release coating is an organopolysiloxane applied from a composition which is curable at temperatures below about 70°C with a curing exposure time of under about 3 minutes, thereby preventing advese effects upon the layer of thermally imageable material.   The release coating serves to prevent the transfer of toner powder from an original to the transparency film.

Abstract: Abstract A surgical drape support for use in eye surgery or other surgery, for maintaining adjustable support of surgical drapes above the patient's nose and mouth, creating a small tent into which oxygen is supplied by a hose, allowing the patient to breathe freely. With the front legs of the support placed between the patient's shoulders and the operating table the greatest stability is achieved and the rear legs find their best location as the support is adjustably positioned for height by raising or lowering the frame on its legs with the locking screws just loose enough for a pivoting motion. The knurled locking screws are tightened to maintain the prefixed position and four point stability of the instrument on the operating table, resulting in a more relaxed state of mind for both patient and surgeon.
