Abstract: A circular scan reader utilizes oscillating mirrors and associated optics to generate a circular scan pattern of laser light focused to a small spot. The angle of the scan emanating from a point just inside the reader through a window forms a conical shape which permits scanning inside a yarn tube without inserting any portion of the reader into the tube. When the scan passes over a bar coded label, the changes in reflection of light between the bars and spaces are detected by a photodetector mounted on the face of the window. These fluctuations in light which correspond in width to the bar and space width are converted to an electrical signal that is amplified, and decoded. A driver circuit for the oscillating mirrors controls the scan rate and scan pattern. The scan rate is modulated to cause a variation in the sweep depth in the tube thus providing an area scan. The area scan reduces the need for accurate label placement in the tube core.

Abstract: A web of undulate wire is converted into a series of coherent C-shaped binders of the type known by the trademark Wire-O and used to bind stacks of paper sheets or the like in the making of steno pads, brochures, calendars and similar stationery products by continuously moving the web lengthwise at a constant or variable speed, by imparting to successive increments of one marginal portion of the moving web a concavo-convex shape in stepwise fashion so that the one marginal portion resembles (in cross-section) one-half of the letter C, and by thereupon imparting to successive increments of the other marginal portion of the moving web a concavo-convex shape in stepwise fashion so that the thus converted other marginal portion becomes a mirror image of the converted one marginal portion. The imparting steps include deforming the respective marginal portions from the inner toward the outer edges thereof.

Abstract: An improved industrial multistage recirculating-fluidized-bed reactor for producing chlorine and iron oxide having an initial "dense" zone and a downstream "dilute" zone. In the dense zone, a fuel is burned, reactants and recirculated iron oxide particles are heated, ferric chloride is vaporized and at least 50% of the ferric chloride is converted to chlorine and iron oxide. In the downstream dilute zone, a solids fraction from 0.005-0.05 is maintained, along with a superficial gas velocity from 1.5-6 meters/second which is from 5-25 times the superficial gas velocity in the dense zone, and the conversion of ferric chloride is continued to greater than 95% completion.

Abstract: To a dispersion of a complex of 3 moles of 4,4'-methylenedianiline with 1 mole of a specified inorganic salt in an inert liquid, which still contains some free methylenedianiline, there is added, with agitation, at least 0.5 equivalent of an organic isocyanate per equivalent of free methylenedianiline. Then, there is added, while continuing agitation, at least 0.5 weight % of lecithin. The resulting dispersion is a good curing agent for isocyanato-terminated polyurethane prepolymers. Compositions containing both the prepolymer and the curing agent of this invention have good shelf stability at room temperature and cure to polyurethane products having good physical properties and hydrolytic stability.

Abstract: The present invention relates to high chromium ferritic stainless steels having improved corrosion resistance and weldability.

Abstract: The instant invention relates to a process for preparing novel insecticide-polymer particles. The process consists essentially of dissolving the insecticide, methomyl, and a polymer in a solvent in which both are soluble. The solution is then comingled with a non-solvent for both the polymer and the methomyl under high shear conditions. A particulate product is formed consisting of irregularly shaped particles having methomyl embedded in a polymer matrix. The irregularly shaped particles may be dispersed, e.g. in water, and sprayed readily into an area of insect infestation.

Abstract: Imidazolylethoxy derivatives of quinoline-2- or 4-methanols having the general formula ##STR1## and their acid addition salts are useful as antifungal and antibacterial agents.

Abstract: Polyurethane prepolymers having free isocyanate groups are treated with polyfunctional isocyanate-blocking agents to cause branching prior to or simultaneously with the addition of a curing diol. The composition containing the curing diol is molded in a conventional equipment at a conventional temperature, e.g., 100.degree.-120.degree.C. The resulting shaped article can be demolded in a fraction of the time required in the absence of the blocking agent. The shaped article is then post-cured within a temperature range of about 25.degree.-150.degree. C., during which time the curing diol, if present in sufficient amount, displaces the blocking agent and forms a cured, linear polyurethane. A typical suitable blocking agent is a substantially uncrosslinked phenol/formaldehyde resin. The curable composition can be prepared in one step from the diisocyanate, glycol, and blocking agent; and a composition containing all the components, including the curing diol, can be prepared in one or more steps.

Abstract: A fiberfill blend for making into a batt for heat-bonding, consisting essentially of three ingredients: (a) two of the ingredients are crimped polyester staple fiber; (1) one of these polyester fiberfill ingredients is slickened with a durable coating; (2) the other of these polyester fiberfill ingredients is unslickened; each of ingredients (1) and (2) constitutes 25 to 75% of the polyester fiberfill (a); (b) the third ingredient is crimped binder fiber of a polymer having a melting point lower than that of the (a) ingredients; the binder fiber is present in amount 10 to 30% of the blend; the remaining 70 to 90% of the blend is the polyester fiberfill. Such blends can be processed on conventional textile machinery, e.g., by carding and cross-lapping, and heated to activate the binder fibers and make a stable heat-bonded batt. Preferred batts, using polyester staple fibers of regular denier, have surprisingly high resilience, which makes them especially suitable for use in pillows and cushions.

Abstract: A spin tuned magnetron (FIG. 2) includes a spinner 3 which interacts with a magnetron cavity to modulate its frequency of oscillation. The spinner runs in bearings 8, 9 around a shaft 7. The lives of the bearings are a controlling factor in the life of the magnetron.The outer races OR are fixed in position relative to each other and to the spinner by spacers, 13, 14 and a spring 15 arranged between an abutment 11 and a circlip 12 on the spinner. The inner races are arranged to be moveable relative to each other and to the shaft by virtue of spacers 10 and 17, a spring 16 between the inner races, and a further spring 18. A pole-piece nose 4 is arranged to be screwed down on the shaft to compress the springs 16 and 18 to provide a desired amount of axial float on the spinner. By setting the axial float the bearing load can be shared as desired and thus increase the lives of the bearings.

Abstract: A coating composition of a urethane polymer has film-forming constituents of an organic polyisocyanate, a low molecular weight hydroxyl-functional acrylic copolymer, and a low molecular weight hydroxyl-functional polyester based on branched-chain glycols. The composition can be applied at environmentally-acceptable solids levels and cured at ambient temperatures to form a durable film.

Abstract: High molecular weight processible polymers derived from 2,6- and 2,7-diacids, diols and diamines of 9,10-dihydro-9,10-ethanoanthracenes and various complementary comonomers are prepared. These are converted into rigid, thermally-stable anthraceno polyesters and polyamides by thermal removal of the 9,10-ethano bridge.

Abstract: An improved rock-bolt grouting composition based on a cross-linkable unsaturated polymerizable polyester resin formulation in one component and a peroxide catalyst in a separate component, contains diffused water, preferably in the catalyst component, in an amount sufficient to provide a weight ratio of resin formulation to water no greater than about 6.0, and a particulate solid filler in both components in an amount sufficient to provide a weight ratio of filler to resin formulation of at least about 3.0. The filled, water-extended composition generally expands during the cross-linking of the polymer, and greater interfacial strength in smooth-walled boreholes has been found. Compositions in which water is the catalyst vehicle are preferred because their shelf life is better than those containing an oil-based catalyst.

Abstract: A branched light-transmission network includes at least one body with a plurality of light-reflecting surfaces meeting in a common point or edge for illumination by a primary light guide, such as a light-conducting filament or foil, emitting a beam which is split among these surfaces into several components directed toward respective secondary light guides. Each reflecting surface is part of an optical system forming two conjugate points respectively coinciding with the centers of the proximal ends of the primary and secondary light guides emitting and collecting the rays reflected by that surface. These conjugate points may be the foci of an ellipse partly defined by the intersection of the reflecting surface with the common axial plane of the associated light guides; alternatively, they are the focal points of two lenses of positive refractivity which define paths of parallel light rays impinging upon and departing from the flat reflecting surface.
