Abstract: The present invention is a shelf divider for separating groups of products arranged on display shelves or the like and takes the form of a relatively thin vertical panel or partition which is self-maintained in upstanding condition on the shelf surface by laterally extending stabilizing feet adjacent each end and is preferably molded from tough, durable plastic. The partition is made of two (or more) co-planar sections interconnected in adjacent abutting pairs by at least one telescoping longitudinally extending mating elongated U-shaped tongue and slot connection permitting lengthwise adjustment of the sections to fit different shelving widths. The tongue and slot are held against lateral disengagement by shaping their proximate upper and lower edges as V-shaped (in cross-section) protrusions and grooves which mate together while permitting relative longitudinal movement of the sections.

Abstract: A temperature-time-pressure detecting device for a closed heat treatment zone consists of a sealed discoidal-shaped capsule of substantially transparent material adapted for placement within the zone in a generally vertical position. The capsule is formed of two opposed preferably symmetrical circular shell walls sealed around their common rim and defining therebetween a central core region containing a shaped mass of a fusible indicating material having a defined melting point at least as high as the temperature to be detected. The central core region is surrounded by an inner and an outer annular chamber which are concentric with the core region and with one another.

Abstract: A process for extracting oil-containing nutmeat pieces to reduce the oil content by at least 25% by contacting the nutmeat pieces in an extraction vessel with liquefied hydrocarbon solvent having 3 to 4 carbon atoms under low liquefaction pressure to form a micella, separating the micella from a marc derived from the mass of nut pieces, contacting the marc with a second amount of solvent for at least two hours to form a second micella and separating the second micella from the marc and repeating this step until the oil content of the nutmeat pieces is reduced by at least 25%.

Abstract: Ultra-clean isotropic coke is obtained from bituminous coal by extracting such coal following the extraction procedure described in U.S. Pat. No. 4,272,346, issued Jun. 9, 1981, to Stiller et al., using, for example, N-Methyl Pyrrolidone as the extraction solvent, and subjecting the extracted solids after separation of the solvent to a conventional coking heat treatment. The isotropic coke thus obtained can be ground, mixed with conventional binder pitch and shaped into carbon products which can be used directly, e.g. as carbon electrodes, or can be subjected to a graphitizing heat treatment under the usual conditions to produce isotropic graphite structures of high purity and high quality. The graphitization can be a multi-stage procedure and the porous intermediate stage products can be impregnated with a conventional impregnating pitch for increased density, the impregnating pitch being graphitized in the subsequent stage.

Abstract: A new class of binders for binding finely divided inert inorganic molding particles when shaped into objects by known mechanical shaping techniques such as injection molding. The novel binders are solid polymer solutions containing a major fraction of a low molecular weight solid relatively non-volatile chemical as solvent in which is substantially dissolved a minor fraction of at least one high molecular weight solid polymer. The solid polymer solution binders when molten are homogeneous solutions and can be readily uniformly mixed with the usual inorganic molding particles into a readily flowable mixture which can be shaped and solidified. When solidified, the polymer and solid chemical remain a substantially homogeneous solution without appreciable phase separation.

Abstract: A stack of photographic sheets is arranged between two rectangular sheets of lighttight wrapping foil. The foil sheets are of a size larger than the stack so that their side margins project laterally exteriorly of the stack in sandwiched relation to form flaps on all sides of the stack. The flaps are initially lighttightly closed, e.g. sealed together, along their peripheral margins. The wrapped stack is lighttightly enclosed within a package having a base and a cover. The base has upstanding side walls arranged in a rectangle large enough to contain the wrapped stack and may include a solid bottom wall. The cover is light-impervious and has margins overlying the top edges of the base side walls in lighttight clamping contact therewith with inner regions of the projecting sheet flaps gripped therebetween to lighttightly close said flaps inwardly of their edges. The initial closure along the flap margins can now be removed to free edges of the flaps.

Abstract: In the digital processing of radiographic images, interpretation of the image is aided by converting the pixels of an original radiographic image into electrical signals generally corresponding to the densities of the individual pixels and adjusting the electrical signals for the pixels constituting a diagnostically non-relevant image zone, selectively of the pixels constituting a diagnostically relevant image zone, as determined by observation of a visualization of the original radiographic images, e.g. by a radiologist viewing such image on the screen of a viewing monitor, to a density level such that when the electrical signals including the adjusted signals are visualized into an image for interpretation, the pixels of the diagnostically non-relevant zone are effectively masked out and light from the non-relevant zone is prevented from interfering with viewing of the relevant zone. Various predetermined configurations, e.g.

Abstract: A display stand for display placards includes a support base formed of a preferably flat bottom wall, upstanding opposite side walls, and an interior partition wall defining between them two generally upwardly opening channels separated by the partition wall, and a cooperating pair of resilient transparent normally flat plastic sheets having their respective lower margins engaged in the channels with most of the remainder of their area in face-to-face planar contact for receiving the placard sandwiched therebetween.

Abstract: A cross-laminate of two or more individually stretch oriented films where the directions of orientation of the films are in criss-crossing relation, has a pattern of generally parallel elongated ribs extending lengthwise of the laminate. The ribs are defined between generally transversely coincident convex and concave curved surfaces on opposite faces of the laminate, the concave surface having a radius of curvature greater than that of the convex surface so that the ribs have a thickness greater than the average thickness of the laminate. The laminate material adjacent to lateral boundaries of the ribs is in a tensionless state reversely curved relative to the rib curvature making the material between adjacent pairs of ribs generally flat. The rib pattern is preferably regular with a preferred average transverse spacing between adjacent ribs, measured peak to peak, of about 1-10 mm. The convex surfaces of the ribs can all be on the same side of the laminate or can alternate in series between opposite sides.

Abstract: Acetylcholinesterase and/or a receptor of acetylcholinesterase is immobilized on a solid support and stabilized by covering with a protective film of gelatin and/or albumin containing trehalose. The film is applied by covering the immobilized acetylcholinesterase and/or receptor of acetylcholinesterase with a layer of a gel-forming solution of gelatin or albumin in an evaporable solvent containing dissolved trehalose, and evaporating the solvent to leave the film. The film provides stability against dry heat, organic solvents, proteases and changes in pH. Other additives such as polyhydric alcohols, organic solvents, polymers and/or ionic and non-ionic components may be present to increase stabilization. A diagnostic kit or chromatography column may be formed containing the stabilized immobilized acetylcholinesterase and/or receptor of acetylcholinesterase.

Abstract: Apparatus for processing a photographic sheet material in at least one processing stage which includes a feed roller array for transporting the material to or from the stage. The feed roller array has a pair of rollers supported on shafts for rotation and mounted with one superposed generally above the other. The upper roller is driven in a transport direction by a drive mechanism acting on an end of its shaft. The opposite ends of the shafts of the two rollers are journaled in frame members with the lower roller being supported for limited independent movement toward and away from the upper roller. The lower roller is normally biased into contact with the upper roller and is adapted to be displaced vertically away from the upper roller by a cam arrangement acting on the ends of its shaft. The upper roller is adapted to be shifted axially to disengage an end of its shaft from its journal to permit the upper roller to be removed manually from the apparatus.

Abstract: The present invention provides an assembly of a first panel formed with at least one insertion notch extending inwardly from at least one panel edge and a second panel carrying at least one projecting tab extending outwardly of at least one of its edge and fitting in one of the notches. The tab has on at least one of its sides a shoulder defining an edge which is located along the projecting length of the tab at a position intermediate the free edge of the tab and its base, which usually coincides with the edge of the panel from which it projects. The shoulder edge is in abutting contact with a region of the first panel adjacent the insertion notch in the first panel in which the tab fits and functions to maintain the associated edge of the second panel out of contact with the first panel so that the relative positions of the panels is determined by such abutting contact and is independent of other factors, such as the precise linearity of the panel edge.

Abstract: The present invention provides an assembly of a first panel formed with at least one insertion slot and a second panel carrying at least one projecting tab extending outwardly of at least one of its edges and fitting in the slot. The tab has on at least one of its sides a shoulder defining an edge which is located along the projecting length of the tab at a position intermediate the free edge of the tab and its base. The shoulder edge is in abutting contact with a region of the first panel adjacent one of the insertion slot and thus maintains the associated edge of the second panel out of contact with the first panel so that the relative positions of the panels is determined by such abutting contact. The first and second panels can be positively secured together by means of an interconnection element, preferably in the form of an integral flange bent up from one of the panels, which is attached to one or both other panel by screws, bolts and nuts or similar attachment devices.

Abstract: A double-sided differentially adhesive adhesive tape is applied to the winding core of a web processing machine, e.g. for producing light-sensitive photographic film, by a dispensing unit carried on a linearly movable support. In the unit, first and second tape applicator rollers are mounted for rotation on the support for engagement upon movement of the support to operative position with the core periphery at peripherally spaced apart points thereon, Tape extends from a supply roll to the first and then to the second roller for application of a winding thereof to the core upon rotation of the latter. The second roller is mounted on the support for limited independent movement after application of the tape winding to a position separated from the core and from the tape, such movement being in a direction generally tangential of the core periphery to avoid lifting the tape from the core.

Abstract: Processing liquid supply system for the processing vessel of photographic processing apparatus wherein fresh processing liquid is delivered from and used liquid returned to a liquid storage container via corresponding conduits which may each include a liquid flow pump. The container is equipped with a push-in/pull-out cap penetrated by passageways communicating with the conduits. The cap is insertable into the container mouth and has an expandable resilient seal around its periphery for sealing engagement when expanded with the internal surface of the container mouth. A handle is pivoted on the cap for movement between cap-sealed and cap-unsealed positions. The cap has an internal piston which is linked to the handle and is displaced axially when the handle is pivoted between its positions to thereby alternatively compress the seal to expand the same and seal the container mouth and relax the seal for removal of the cap from the container.
