摘要:
The present invention relates to an adhesive closure system. More specifically, this invention relates to an adhesive closure system with an abridged release liner. Initially, the abridged release liner allows partial exposure of the single adhesive layer to achieve a temporary bond. When desired, the release liner can be removed exposing the remainder of the adhesive to achieve a permanent bond. This type of closure system has numerous applications including the closure system for pipe insulation sleeves.

An apparatus detects the presence and location of at least one object in a field. The apparatus comprises a rotating arm which spins around the field, a position sensor for detecting the angular displacement of the rotating arm relative to a fixed point, and a processor. The rotating arm includes a transmitter and an opposing receiver array mounted thereon and fixed relative to each other. The receiver array includes a plurality of receivers located horizontally coplanar with each other. The receivers are concentrated towards one side of the receiver array which is aligned with a center region of the dartboard. The transmitter outputs a detection beam that emanates from a single point, such as a divergent beam. The detection beam overlaps the field and is simultaneously received at all times by the plurality of receivers of the receiver array. The receivers detect changes which occur in the field as a result of an object being in the field, manifested by shadows on the field. The processor receives output signals from the plurality of receivers and angular displacement data corresponding to the output signals, and determines therefrom the presence and location of an object in the field. The field may be a dartboard front surface and the detected object in the field may be a dart which lands on the dartboard front surface. The dartboard may be a Bandit.RTM. dartboard. The dartboard may be mounted in a housing wherein the front of the housing includes an outer catch ring area having a plurality of removably attachable catch ring segments made of dart-permeable and dart catching material. The processor detects when a player's turn is over by detecting removal of the darts from the dartboard, and automatically advances a scoring display to the next player.

A flexible thin film battery including a film layer and a porous cathode deposited on a portion of a film and a porous anode deposited on a portion of the film, with an electrolyte and separator layer positioned between the porous anode and the porous cathode. The electrolyte is preferably dried so the battery is activated when liquid contacts the electrolyte and separator layer. In a preferred embodiment, water swellable particles are included in the cell. The film layers are least partially sealed around the edges, confining the anode, cathode, and electrolyte and separator layer. The method of producing such a battery preferably includes printing various inks in a pattern on a polymeric film.

Adhesive laminates and their preparation. According to one embodiment, an adhesive laminate comprising a foamed pressure sensitive adhesive layer and a release liner applied thereto is prepared by applying hot pressure sensitive adhesive material in layer form to a release coated surface of a release paper or other release liner. Moisture is transferred from the release liner to the hot molten adhesive layer, causing the latter to foam. According to a second embodiment, a coextrudate comprising a thermoplastic carrier with an adhesive coating on one or both sides thereof is formed by the coextrusion of the adhesive taking place with the carrier over at least a short distance and at a temperature of about 350.degree.
