  • Patent number: 6594535
    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.

  • Patent number: 5440480
    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.

  • Patent number: 4906424
    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.

  • Patent number: 4360541
    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.

  • Patent number: 4101399
    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.
