Abstract: A curable composition and method for producing a tear resistant, yet soft and deformable in-the-ear product yielding the user greater comfort and durability. The curable composition incorporated into a hearing aid apparatus provides a deformable, yet tear resistant housing, which may be mated to a soft tip component. The hearing aid housing provides better comfort, durability and acoustic performance for a variety of ear canal shapes. The curable composition that provides these properties includes at least one urethane acrylate oligomer, at least one reactive diluent and a cure system. The composition when cured desirably produces a tear strength of at least about 75 pli and a hardness of about Shore A 60 to about 75.

Abstract: A dispensing apparatus provides for the dispensing of product from a collapsible tube. The apparatus includes a body for supporting the tube. The body has a forward end for accommodating a dispensing end of the tube and rearward end for accommodating a closed end of the tube. An elongate actuatable plunger is supported by the body. The plunger includes an elongate rod and a base attached to the rod. Actuating means is provided for effecting movement of the plunger in a first direction along the body for engagement with the collapsible tube wall thereby deforming the tube wall and dispensing the contents of the tube from the dispensing end. The actuating means also provides for retractable movement of the plunger in the second direction opposite the first direction. The base is positioned on the rod for dispensing engagement with the tube upon movement of the plunger in the first direction and movable out of dispensing engagement with the tube upon in a second direction.
Abstract: A sheet product is provided which comprises a scrim embedded in a continuous layer of a foamed resin. The sheet material is useful as a drawer liner or a shelf liner and is fabricated without need for lamination of separate layers to a scrim material.

Abstract: In accordance with the present invention, there are provided novel benzoxazine compounds and thermosetting resin compositions prepared therefrom. Invention compositions are particularly useful for increasing adhesion at interfaces within microelectronic packages. Invention benzoxazines are useful for the preparation of invention compositions with properties which are associated with increased adhesion at interfaces, such as, for example, low shrinkage on cure and low coefficient of thermal expansion (CTE). In another aspect of the invention, there are provided die-attach pastes having increased interfacial adhesion. Invention die-attach pastes include benzoxazine-containing thermosetting resin compositions. In further aspects of the invention, there are provided methods for enhancing adhesive strength of thermosetting resin compositions and methods for enhancing adhesion of a substrate bound to a metallic surface by a thermosetting resin composition.

Abstract: The present invention involves a hand-held cutter device that is adapted to be held by a human hand, over a human finger, or between the human fingers. The cutter device includes a generally cylindrical inner sleeve slideably engaged with a generally cylindrical outer sleeve, where each sleeve includes an open end and a closed end. The inner sleeve has an extended position and a retracted position. A blade for cutting various materials is attached to the closed of the inner sleeve. A biasing element is confined between the sleeves and urges the inner sleeve into the retracted position. The closed end of the outer sleeve may include a plurality of flat guide surfaces, at least one straight guide groove, and or at least one guide rib. At least two of the plurality of flat guide surfaces may intersect at about a 90 degree angle and the at least one straight guide groove may be located within any of the plurality of flat guide surfaces.
Abstract: The present invention provides a high output LED assembly including a heat sink (18) and an LED (14) mounted at one end of the heat sink (18). The LED (14) is in electrical engagement with the heat sink (18). The assembly also includes a conductive reflector (12b) mounted to the heat sink (18), surrounding the LED (14). An insulative member (19) is provided between the reflector and the heat sink. The assembly further includes an electrical engagement directly connecting the LED (14) to the reflector (12b) to provide an optimum connection for a high output LED assembly.

Abstract: A shelf liner (10) with a natural appearance includes a skid-resistant first major surface and a decorative second major surface. The shelf liner includes a scrim (12) and a foamed resin (14), which is in contact with the scrim. The resin leaves at least a portion of the scrim exposed on the second major surface.
Abstract: The reaction of diner acids, C10-C20 dicarboxylic acids, and alkylene diamines having from 2 to 8 carbon atoms provides polyamides having good oil and solvent resistance, high heat resistance, flexibility, and relatively low melt viscosities.
Abstract: An acid inhibitor concentrate is provided which contains water, at least one polyamino-aldehyde resin such as a quaternized polyethylenepolyamine-glyoxal resin, and at least one compound selected from the group consisting of acetylenic alcohols, ethoxylated fatty amines, ethoxylated fatty amine salts, and aldehyde-releasing compounds (such as hexamethylenetetramine). Such concentrates form useful metal cleaning and pickling solutions when combined with aqueous acid, wherein such solutions, when contacted with a metal surface, are effective in removing scale, smut and other deposits from the metal surface but exhibit a reduced tendency for the aqueous acid to attack or etch the metal itself.

Abstract: In accordance with the present invention, it has now been found that glycidyl epoxy resins containing substitution on the epoxide ring can be used with conventional epoxy curing agents and fluxing agents to produce underfill adhesives that are suitable for use with silver-based alloys. Owing to the structural similarity of the new materials to conventional epoxy resins, physical and material properties of the invention formulations are altered little, if at all, relative to products currently in use, and so are highly compatible with existing processes.
