Abstract: A material flow design system for a mixed-model demand flow manufacturing line is presented. The material flow system utilizes a replenishment card/replenishment container system of material management. The material flow design system defines the size of replenishment containers and the location of material deduct points in the production path. The material flow design system may further include a design system for designing an inventory control system. The inventory control system involves locating backflush and intermediate backflush locations on the production path and deduct points in the material flow sequence. An inventory monitoring system monitors material flow, deducts material from inventories at deduct points, and credits material to inventory indicated by the deduct points when products produced by the manufacturing line flow through material backflush points defined in the manufacturing line.

Abstract: A demand-driven, mixed-model manufacturing line design system utilizes Demand Flow Technology to design an efficient mixed-model manufacturing line. Concurrent manufacture of several products in a continuous flow, mixed-model product line designed utilizing the design system exhibits essentially none of the inefficiencies associated with mixed-model, batch-oriented manufacturing lines.

Abstract: A system that determines the total demand for a product for each day over four time periods specified by the user of the system. Within the first time period, from the current date up to a demand fence, the total demand cannot be altered. For the next three periods, called the flex fence periods, the total demand for each day can vary by a percentage amount set by the user. If an order exceeding capacity is received for a date beyond the demand fence, the system will recalculate total demand for all days beyond the demand fence and prior to the order date to attempt to produce the total demand quantity necessary to fulfill the order. In calculating the increased quantities, the system uses a formula that prevents the total demand quantity for any day from exceeding the amount of material that was ordered for that day.

Abstract: A polyarylate is formed by reacting a mixture of a diester of a dihydric phenol, at least one aromatic dicarboxylic acid and an inert diluent comprising a poly(fluorinated alkylene oxide). Polyarylates of improvided color can be formed and the diluent can be easily separated from the polyarylate and reaction byproducts.

Abstract: A process is described for producing shapable aromatic polyesters derived from bisphenol A and a dicarboxylic acid comprising isophthalic acid, terephthalic acid, or a mixture of the two, comprising forming a mixed anhydride of said dicarboxylic acid and acetic acid, and subsequently reacting said mixed anhydride with bisphenol A while drawing off acetic acid by-product to obtain said aromatic polyester.

Abstract: Greenbodies are produced by a RIM injection molding process wherein a homogeneous mixture of finely divided ceramic or metallic material and a polymerizable monomeric binder is injected into a mold and held at an elevated temperature for a sufficient time to polymerize the binder and form the greenbody. A preferred monomeric binder includes di- and tri-acrylate or -methacrylate esters of polyols. The low viscosity of the monomeric binder allows a loading of ceramic material of greater than 50 vol. % without adversely affecting the ability to injection mold the mixture.

Abstract: An emulsifiable concentrate of Imidan, an acrylic resin, a surfactant and a common organic solvent functions as a controlled release insecticide when applied to plant foliage.

Abstract: Thermosetting resin coatings are provided which cure rapidly and exothermically at ambient temperatures. Accelerated crosslinking is accomplished by the reaction of oxalic acid esters with amine-containing polymeric compositions.

Abstract: The use of acrylate or methacrylate esters of polyalkylene oxide derivatives of alkyl/aryl phenols as wetting agents and adhesion promoters in ultraviolet curable systems is disclosed. These materials may be added to the ultraviolet system in a quantity between about 5 and 50 weight percent, based on the total weight of the ultraviolet curable composition.

Abstract: This invention provides a process for preparing self-pigmented ultraviolet cured coating compositions, which involves preparing a dispersion of water in certain polyunsaturated ultraviolet curable monomers at a solids level of about 35 to about 85 weight percent, applying the dispersion as a coating on a substrate and curing the substrate coating by exposure to ultraviolet light. These cured compositions have utility as self-pigmented protective coatings.

Abstract: The preparation of rapidly curable ultraviolet coating compositions utilizing, in addition to standard photoinitiators, an aromatic sulfide is disclosed. Utilized in conjunction with the aromatic sulfide may be a triplet state sensitizer, such as a fused ring aromatic compound.

Abstract: This invention relates to the irradiation of compositions comprising non-ethylenically unsaturated brominated and chlorinated aromatic polyester fibrous materials with low intensity ultraviolet light radiation for relatively brief periods of time under appropriate conditions to yield a product of enhanced solvent resistance. The irradiation of the halogenated polyesters (as defined) generates free radicals within the fibrous material which react to produce sufficient cross-linking to enhance solvent resistance without a significant detrimental change of other product properties.

Abstract: There is disclosed a direct roll coating technique whereby a continuously revolving silk screen is interposed between the roll coating roll and the substrate to be coated. This silk screen serves to eliminate ridges which are usually formed when a direct roll coater is used. This technique is of special usefulness where ultraviolet curing of the coating on the substrate is contemplated.

Abstract: An improved process for applying an ultraviolet curable coating to tin free steel is disclosed in this invention, whereby prior to applying the main ultraviolet curable composition, a thin pre-coating of a monomer containing at least one ultraviolet polymerizable site of alpha beta ethylenic unsaturation and at least two carbonyl groups is first applied to the surface to be coated, to a thickness of at least about 10.sup..sup.-3 microns, and heated at temperatures ranging from 50.degree. to 125.degree.
