Abstract: The improved method and apparatus for longitudinal orientation of a tubular thermoplastic film as it leaves an annular extrusion die aims at a better control of this orientation. On its travel between the exit orifice (21) and the draw-down means, the at least partly molten film passes an annular frictional device (101), and the frictional force set-up hereby is variable in controlled manner. This device is cooled from its interior (105) in controlled manner by means of a fluid cooling medium. The friction may be controlled by airlubrication with air pressed through holes (123) in the frictional device or through microporous metal, (102) or alternatively by sucking the film against the frictional device.
Abstract: A pusher accessory for assembly conventional elongated product display hooks configured at one end for anchorage on a supporting panel or board and supporting in suspended fashion along their length a multiplicity of product items for removal from the opposite free end of said hook. The pusher accessory has a stationary component for attachment in fixed position adjacent the free hook end; a movable component mountable on the hook for free sliding movement there along; and an extensible tension spring affixed at one end to the stationary component and carried at the other end by the movable component. When extended by separation of the movable component and intervening product packages suspended from the hook, the spring applies spring tension force to the movable component and intervening packages and advances the latter as product packages are removed. Preferably, the spring is a flat coil spring carried at the coil end by the movable component.
Abstract: A holder for displaying a thin advertising placard on a fixture exhibiting merchandise for sale, has an elongated shank shaped at one end for detachable fixation to the fixture, and carrying at the other end a three-dimensional head for holding the placard. The head has at least one, preferably more, substantially linear slot extending across a portion of its periphery and inwardly into its interior for receiving a marginal portion of the placard. Each such slot on its interior is shaped for gripping the placard portion.
Abstract: A method and apparatus are described for coextruding two materials A and B, in which B is extruded on A through a port (3), in which the separating wall between the flows of A and B is formed as a flap closure (4) adapted to act as a non-return valve for the flow of B into A, and further means are provided for extruding B through the port in pulses. The pulses may be effected by opening and closing the closure, by mechanical transmission means or by the effect of imposing pressure difference on the flap (4) by the flows of A and/or B. The pulsing means preferably involves rams (1). The invention is particularly suitable for extruding a low viscosity material B onto a higher viscosity material A, or for making sheets or pipes with alternating segments of differential flexibility, or for coextruding a flow of solid particles with a flow of liquid.
Abstract: A cross-laminate web is formed of two oriented films, the films being arranged so that the main direction of orientation of the first film (A) generally follows the longitudinal direction (D) of the web and the main direction of the second film (B) is perpendicular (F) to that direction. The coefficient of elasticity of the material of the first film, in an unoriented state, is at least 115% lower than that of the material of the second film, and the heat shrinkability of the first film is greater than that of the second film. Bags formed from the cross-laminate have heat seals with improved shock peel strength.
Abstract: The present invention is an improvement in a method of desolventizing a marc resulting from the extraction of a mass of an oil-containing material with a normally gaseous hydrocarbon solvent for the oil therein after completion of the extraction, the solvent is drained from the marc, leaving residual solvent retained in the marc, and gaseous vapors heated above the solvent boiling point are passed through the zone in contact with said marc to volatilize the residual solvent therein. The improvement involves establishing within the extraction zone a desolventizing region defined between an inlet port and an exit port for the heated vapors and progressively displacing the desolventizing region from adjacent one zone end to adjacent its opposite end, whereby only a fraction of the marc within said closed zone is contacted with the flow of heated gaseous vapors at any given time.
Abstract: Multiple sclerosis in a human patient is treated by the administration via a pharmacologically effective route of an essentially pure opiate receptor antagonist, preferably an essentially pure opiate receptor antagonist exhibiting a substantially higher blocking effectiveness against Mu opiate receptor sites than against Delta receptor sites, exempliefied by Naltrexone and Naloxone, at a low dose concentration which produces therapeutic results corresponding to those produced by Naltrexone when administered in the range of about 1 mg to about 10 mg and at a lelel at which Delta blocking activity is small while Mu blocking activity is significant and most preferably substantially exclusive.
Abstract: Cancer of the prostate in human male patients even at an advanced state with metastasis to other organs, is treated by the administration, preferably at bedtime, to the patient by a pharmacologically effective mode of an essentially pure opiate receptor antagonist, typified by Naltrexone and Naloxone, exerting substantially higher blocking action for Mu opiate receptor sites than against Delta opiate receptor sites at a low dose concentration which produces therapeutic results corresponding to those obtained by the administration of Naltrexone at a low dosage level in the range of 1.0 mg. to 10 mg. per day and at which Delta receptor blocking activity is at most small and Mu receptor blocking activity is substantial. Naltrexone is suitable for oral administration and is preferred.
Abstract: Apparatus for heat-sealing polymer films which shrink when heated include provision for moving the zone of application of heat and pressure during the heat sealing process. This allows for shrinking of the polymer film in a region adjacent to the heat seal so that the film thickens and is more resistant to failure in use through peeling. The apparatus includes a pair of sealing bars (4, 5) one of which (4) is wedge-shaped and the other of which (5) is flat. Both bars are heated and one of them can be moved in direction (12) to apply pressure to film located between the bars. At the beginning of the heat sealing step pressure is applied over an initial zone along the apex of the wedge. Subsequently the bare (4) is rolled around an axis located near to the apex of the wedge, in the direction shown by the right hand end of arrow (13), to apply heat and pressure over a wider zone located adjacent to the initial zone.
Abstract: Lymphoproliferative syndrome, including such diseases as malignant lymphoma, chronic lymphocytic leukemia, Hodgkin's lymphoma, and non-Hodgkin's lymphoma, is treated in human patients by the administration by a pharmacologically effective mode or route of an essentially pure opiate receptor antagonist, typified by Naltrexone and Naloxone, exerting substantially higher blocking action for Mu opiate receptor sites than against Delta opiate receptor sites at a low dose concentration which produces therapeutic results corresponding to those obtained by the administration of Naltrexone at a low dosage level in the range of 1.0 mg. to 10 mg. and at which Delta receptor blocking activity is at most small and Mu receptor blocking activity is significant and most preferably substantially exclusive. Naltrexone is suitable for oral administration and is preferred.
Abstract: An accessory for a dental practitioner during a dental procedure utilizing an instrument held in one hand is in the form of a miniature tray-like holder of tough sharp-point penetration resistant, stiffly resilient material, preferably a thermo-formable plastic, formed with a recess containing a flexible absorbent wiping medium for the instrument, such as one or more small elongated cylinders of conventional quilted dental padding or a flexible cellular foam, is anchored to the back of the opposite hand of the practitioner by means e.g. of a layer of adhesive carried on its underface and adhered to the back of the hand or resilient wings downwardly gripping a finger thereof. The recess is contoured to promote retention of the absorbent material therein The holder preferably also has a well for holding a small vial of tooth polishing paste adjacent to the wiping medium recess for ready access during polishing.
Abstract: A method of treating cancers by administering to a patient an anti-tumor effective amount ot at least one of a thermostable macromolecular antigen complex or a fragment of such a complex which is interspecific for microorganisms of the Mycobacteria, Nocardia and Corynebacteria group and which exhibits after immunoelectrophoresis an immunoelectrophoretic precipitation pattern corresponding to that of the antigen complex 60 of Mycobacteria bovis Calmette Guerin Bacillus strain. Preferably, the patient is also treated with an additional therapeutic agent which is specific against the patient's cancer such as a tumoral antigen or a non-proliferative tumor cell.
Abstract: A collectible structure of delicate frangible hollow construction having a circular or other shaped opening in its rear wall is provided with a relatively axially short protective sleeve of tough composition fitting within the opening and retained therein, e. g. by frictional engagement with the opening edges. An illuminating unit having a light source for illuminating the collectible structure from its interior is placed within the sleeve with the light source disposed within the structure interior beyond the inner end of the sleeve. Attached to the unit are resilient spring supporting means therefor, preferably in the form of plural resilient outwardly-directed fingers, in engagement with an interior surface of the sleeve so that the sleeve surface bears the force of the supporting means. Preferably, the sleeve has a short arcuate segment removed from its perimeter to permit the sleeve to be compressed to fit different sized openings.
Abstract: A graphite of anisotrophy selected between substantially isotropic to highly anisotropic, or calcined coke graphitizable to such a graphite, or a pitch convertible into such a coke or graphite, is derived from bituminous coal. A first coal is extracted in NMP or like solvent to give a first extract that when carbonized alone produces a substantially isotropic coke. A second coal (the same or different as the first coal) is hydrogenated and similarly extracted to give a second extract. The extent of hydrogenation is controlled so that the second extract when carbonized alone produces a highly anisotropic coke. Test samples are prepared by combining the two extracts in differing ratios including one sample in a ratio at each range end of the range. The solids of each sample are recovered, carbonized into coke, and then optionally converted into graphite, and its degree of anisotrophy analyzed. Comparison of the analyzed degrees for the different coke or graphite samples gives an correlation (e. g.
