Abstract: A wood-based blasting material is formed for introduction into a blasting fluid by mixing high-density pellet particles of various sizes. The pellet particles are formed from sawdust or fiber pressed under high pressure, resulting in brittle pellets. The pellets may then be crumbled and screened into particles of an appropriate size. The particles do not disassociate into their constituent materials when mixed with the blasting fluid, and thus maintain their density during use in the abrasive blasting process.

Abstract: A wood-based cement additive is formed by mixing high-density pellet particles of various sizes. The additive is to be introduced into a cement source to create a slurry mixture. The density of the mixture of pellet particles is selected to be less than the density of the particular cement type in which the pellet particles are introduced. The pellet particles are formed from sawdust or fiber pressed under high pressure, resulting in brittle pellets. The pellets may then be crumbled and screened into particles of an appropriate size. The particles do not disassociate into their constituent materials when mixed with the cement, and thus maintain their density during use in the cementing process.

Abstract: A wood-based loss circulation material is formed with a density matched to the density of the drilling fluid to which the loss circulation material will be added. The material is formed from sawdust or fiber pressed under high pressure into high-density pellets. The resulting pellets are brittle, and may be crumbled and screened into particles of an appropriate size for a particular drilling fluid application. Different particle sizes may be employed to prevent seepage or fill voids during the well drilling process. The particles do not disassociate into their constituent materials when in the drilling fluid, and thus maintain their density during use.

Abstract: A golf club head is disclosed. The head has a shell with an inner surface defining a hollow interior portion. The inner surface has a plurality of inwardly extending ribs made of resin and a single continuous filament located in the resin.

Abstract: A golf club head and a method of making a golf club head are disclosed. The method provides for winding a single continuous filament multiple times about a soluble core. The wound core is located in a mold and pressure coated with a pure or non-continuous fiber filled resin. The resin is allowed to cure to form a filament and resin shell about the core. The soluble core is removed leaving the continuous filament in the shell.

Abstract: A clumping animal litter comprises an organic material, a surfactant, and a clumping agent. The clumping agent may be a combination of carboxymethylcellulose (CMC) and guar gum. The material may comprise 1–2% CMC, 3–6% guar gum, 1–5% surfactant, and the remainder wood fiber. The material is formed into pellets with a uniform distribution of the various ingredients. The pellets are then crumbled to improve absorption characteristics. The mixture results in a fully-biodegradable, organic-based litter product with improved clumping abilities, natural odor control, and ease of litter pan maintenance.

Abstract: Producing an encapsulated glazing unit having a weather-stable film on an exposed surface of the gasket. There is provided a two-part mold whose sections cooperate to define a mold cavity for receiving the peripheral margins of the transparent glazing unit upon which the gasket is to be formed. A sheet of the weather-stable film is positioned over the mold section having the portion of the cavity which defines the surface to which the film is to be applied. With the mold closed, a flowable gasket forming material is injected into the mold cavity behind the film to deform the film into conformity with the mold surface. As the gasket cures in situ, the film fuses to its surface. The encapsulated unit is removed from the mold and the excess film is trimmed from around the gasket.

Abstract: Molded composites, useful for manufacturing for example entry way doors, furniture components, building decorative or structural components, etc., are produced by a process in which a substrate and surface finishing film are placed in a mold, the mold is closed, and reactive polymeric precursors are injected between the substrate and the surface finishing film. The injection pressure and the autogenous pressure incident to the curing of the reactive polymeric precursors deform the surface finishing film into intimate contact with a surface of the mold cavity, and simultaneously the polymeric precursors chemically bond to the surface finishing film.

Abstract: A window assembly includes two or more glass sheets and a gasket formed by curing a polymeric gasket material in situ on the glass sheets to encapsulate a marginal peripheral edge thereof and form a hinge between the glass sheets. The hinge is formed as a narrow cross sectional area between portions of the gasket adhered to adjacent peripheral edges of the two glass sheets. The hinge permits the glass sheets to be moved relative to one another. Thus, the glass sheets and gasket can be formed in a substantially planar configuration, can be shipped in said planar configuration, and then can be adjusted to fit into openings in a vehicle or building in a desired configuration.

Abstract: A process for manufacturing tooling, e.g., molds, from individual laminations which when stacked in the proper sequence and bonded together define a forming surface. In producing a mold, cut-outs are made by a 4 or 5-axis cutting means in the individual laminations to provide the shaping surface and optionally passageways adjacent the surface through which a heat transfer medium can be made to circulate. Also, selected ones of the laminations may be spaced in the thickness dimension of the mole to provide communication between the mold cavity and a source of pressurized air or vacuum, or the atmosphere.

Abstract: Fiber reinforced molded plastic articles, without fiber readout surface defects, are prepared in either resin transfer molding or reinforced reaction injection molding processes, by disposing a surface finishing film across the mold cavity prior to the insertion of the fiber preform and the injection of the curable polymeric precursor materials, thereby producing a finished article wherein the surface finishing film is bonded to the surface of the article filling the areas between those fibers near the surface which would otherwise cause fiber readout.

Abstract: Coated plastic products are prepared by chemically bonding a protective coating material to at least a portion of the surface of a plastic substrate, by disposing a web of a protective coating material over the cavity of a mold, and thereafter injecting polymeric precursor materials into the mold behind the web thereby conforming the web to the surface of the mold cavity. As the polymeric precursor materials react in situ to form the plastic substrate, they also chemically bond to the protective coating material.

Abstract: An insert which forms the show or finish surface (this surface exposed to the weather) for an elastomeric gasket in an encapsulated window assembly is thermo formed from a sheet of plastic and placed in the lower half of a mold. A sheet of glazing material is also placed in the lower mold half and an upper mold half is utilized to close the mold cavity. Gasket forming material is injected into the mold cavity to form a gasket in situ which adheres to both the peripheral marginal areas of the transparent sheet and the insert. The insert can be formed with a gate portion which extends into the gate area of the mold and prevents the gasket forming material from flowing onto the surface of the insert which is to be exposed in the final glazing. In one embodiment, the insert can be formed in its final configuration with a central opening leaving the transparent sheet exposed.

Abstract: Molded plastic articles are prepared by disposing a mold release membrane across a mold section, closing the mold, injecting polymeric precursor materials behind the membrane causing it to conform and adhere to the mold cavity surface, and thereafter parting the mold sections and parting the molded plastic article away from the release membrane which remains adhered to the mold cavity surface. Subsequent injections may be used to prepare additional molded plastic articles, thereby reusing the release membrane which at all times remains adhered to the mold cavity surface.

Abstract: The preformed assembly of a transparent sheet material and a gasket adhered to the periphery thereof, and the method for producing the assembly. Preferably, the sheet material is glass and the gasket is formed of a thermosetting polyurethane material. The material, curable to produce the gasket, is injected into a mold cavity and thence by controlling the attendant parameters, the autogeneous pressure incident to polymerization causes the material to be urged into intimate contact with mold cavity and the sheet material. After the material has been cured sufficiently, the resultant assembly is removed from the mold cavity.

Abstract: A window assembly includes a transparent glass sheet and gaskets formed by curing a polymeric gasket material in situ on the glass sheet to encapsulate a marginal peripheral edge portion thereof. A glass sheet to be utilized in a vehicle door has a front edge, rear edge and a lower edge to each of which is adhered such a gasket. In addition, a bracket means for attachment to a scissor linkage for raising and lowering the window can be secured to the lower edge of the window. The gaskets are formed in a mold with the transparent sheet and bracket means, typically by a reaction injection molding process. Each of the front and rear gaskets may have a flange portion thereon for insertion in an opening in a gasket attached to a frame of the window opening in the vehicle door.
