Abstract: A composite material for controlling oxygen flux into a thermal cell (10) comprises a bottom sheet (12) formed to have a pocket (14). The bottom sheet  is impermeable to oxygen. A plurality of particles (20) is placed in the pocket. The plurality of particles reacts exothermally when exposed to oxyge n. A top sheet is sealed to the bottom sheet at a flange around the pocket to enclose the plurality of particles such that the particles cannot fall out o f the pocket. The top sheet has a substrate (22) which is highly permeable to oxygen. The substrate is coated with an oxygen permeable silicone based elastomer (24) to a thickness which regulates an oxygen flux into the pocket  when the top sheet is exposed to oxygen. The composite material further comprises an oxygen impermeable barrier film (28) bonded to the top sheet by  pressure sensitive adhesive (27) for preventing exposure of the top sheet to  oxygen until the body warmer is intended to be used. A method for making a t op sheet material involves coating a silicone rubber layer onto a smooth surfac e, partially curing the silicone, pressing a porous substrate against the silicone rubber layer, and completely curing the silicone rubber such that i t adheres to the substrate.

Granted: 2007-08-14
Abstract: The apparatus for wrapping compressible box-like articles (10) such as a stock of newspapers or magazines, with a web-like wrapping material (12). The apparatus has three serially arranged belt conveyors (16, 18, 20), and the second belt conveyor (18) is in the form of a bearing table (24) which can be rotated about a vertical axis (26). The bearing table mounts two pressure-exerting members (30, 32). The article (10') which is to be wrapped is introduced in a compressed state, by the first belt conveyor (16), into a wrap-around channel (42) which is formed by the table (24) and one of the pressure-exerting members (30), and the wrapping material (70) is positioned around the article in the form of a U. At the same time, the article (10), which has been previously wrapped in this way, is transferred to the third belt conveyor (20). A  guide arrangement (62) for the wrapping material is then moved in a downward direction forming a loop of the material which is composed of a first end section (76) and a parallel second end section (78) which is guided along the trailing side (82) of the article. The loop of the material (70) is then severed at the base of the loop and the bearing table (24) is rotated in order that, as the article (10') is transferred to the third belt conveyor (20), the end section (78) is positioned against the article (10') to complete the wrapping. The first end section (76) is positioned to be engaged by the next article as it is advanced onto the table (24).
