Abstract: This invention relates to a process in which a composition is coated onto a substrate and crosslinked so as to form a PSA by means of polymerizing free radically polymerizable monomers from covalently attached pendent unsaturation in the polymer component of the composition. The coating can carried out by a wide variety of industrial methods because the process of the invention allows for compositions with a wide degree of possible viscosities.

Abstract: The present invention provides a fastener which does not generate noise when it is engaged to an article and vibration is applied thereto.The fastener comprises a base portion, a stem portion implanted and interconnected to the base portion in a spaced-apart relationship by a predetermined distance from the base portion, and a head portion interconnected to the distal end of the base portion. At least a part of the stem portion or the head portion comprises (1) a polyphase polymer material having a first polymer resin and a second polymer resin, or (2) a polymer resin that increases the flexural modulus of the fastener.Since the fastener does not generate noise during vibration, it is useful as a fastener particularly for fitting automobile components together.

Abstract: A granular material is presented comprising inorganic particles coated with an organometallic polymeric binder, the organometallic polymeric binder comprising the reaction product of water with at least one component of a binder precursor composition. The binder precursor composition is selected from the group consisting of 1) a first composition comprising an inert organic polymer and a hydrolyzable liquid organometallic solvent; 2) a second composition comprising a water reactive organic polymer dissolved in an inert organic solvent; and 3) a third composition comprising the water reactive organic polymer dissolved in the hydrolyzable liquid organometallic solvent.

Abstract: An antenna adapted for placement in the window of a vehicle includes a flexible substrate having a pair of opposing surfaces, at least one of which is provided with electrically conductive metal traces in the form of a pattern configured to receive and transmit one or more electromagnetic signals. The pitch, trace width, and thickness of the metal traces are selected such that the antenna has an area-averaged resistivity of no greater than about 1 ohm/square for a pre-determined area-averaged transmission value in the visible region.

Abstract: An efficient, light-weight airbag inflation filter includes a gas-permeable, substantially rigid support tube having a plurality of uniform perforations therethrough. A filtering element formed from a continuous inorganic ceramic yarn or roving is helically cross-wound around the support tube to form one or more layers covering the perforations of the support tube. A wire screen, having openings therethrough smaller than the perforations in the support tube, is disposed between the filtering element and the support tube to act as a gas diffusion layer for the gases passing through the inflation filter.

Abstract: The present invention is an apparatus and method, for improving the ability of a person to handle a piece of sports equipment, which uses one or more gloves operatively adapted to make each hand wearing a glove develop a heightened sense of touch and/or improve the person's ability to concentrate on handling the sports equipment, when the sports equipment is handled for a sufficient period of time while wearing the glove. The present invention enables a person to handle the sports equipment with more confidence and authority. The present method includes the steps of providing at least one such glove, wearing the glove on a hand, and handling the sports equipment with the gloved hand until the ability of the person to handle the sports equipment, with the glove removed, is improved.

Abstract: An improved fibrous glass insulation assembly (10) having a fibrous glass body (12), a moisture barrier (14) that substantially encloses the fibrous glass body (12), and a desiccant (18) positioned adjacent the fibrous glass body (12) and within the moisture barrier (14). The fibrous glass body (12) is sufficiently encapsulated or enclosed by the moisture barrier (14), the moisture barrier (14) sufficiently retards the passage of moisture therethrough, and the desiccant (18) is disposed in a sufficient quantity so that enough moisture is removed to improve the recovery performance of the fibrous glass body (12), from a recoverable compressed state, and/or to improve the stiffness performance of the fibrous glass body (12), once the glass body (12) has recovered.

Abstract: Apparatus and methods for enhancing an electronic audio signal by adding enhancing harmonics to the electronic audio signal. The present invention includes a field inducing coil through which input electronic audio signals are to be transmitted to set up an electromagnetic field. The field inducing coil is weakly coupled to an electromagnetic field receptor such that when an input electronic audio signal is transmitted through the inducing coil only a small portion of the electromagnetic field cuts or passes through the field receptor in order to produce an induced electronic audio signal having a greater harmonic content than the input electronic audio signal.
Abstract: A cleat for mounting onto the working face of a wheel of a compaction machine. The cleat has a cutting face, two ends, two side faces and a bottom face. Each of the side faces is located on either side of the cutting face and slope downward toward the bottom face and generally toward opposite ends of the cleat.
