Abstract: A bleacher seat cover and a bleacher seat containing same are disclosed. The bleacher seat cover is of a resilient polymeric material such as an extruded thermoplastic material. The profile of the bleacher seat cover is formed such that the profile of the cover can be distorted from its original shape to a tensed shape, to allow it to be slid over a bleacher seat. Once released from the tensed shape, the resilience of the cover allows it to exert a spring static force against the side(s) and bottom of the bleacher seat to hold the cover in place. In a preferred embodiment, the cover member has a profile that defines a figure wherein the top portion is represented by a straight line; each side portion is represented by a straight line extending at least ninety degrees therefrom; and each bottom portion is represented by a straight line extending at less than ninety degrees from the side from which it extends.

Abstract: The present invention relates to an extruded fluoropolymer-acrylic composite and a method of producing same. The extruded product of the present invention comprises a layer of at least one first polymeric substance comprising a mixture of: (1) from about 1 to about 70 percent by weight of at least one acrylic material, (2) at least one fluoropolymer, and (3) at least one inorganic pigment in sufficient amount to render the first polymeric substance reflective to infrared light and opaque to both ultraviolet light and light and light having a wavelength of about 350 to about 2500 nanometers; in contact with a layer of at least one second polymeric substance being of a chemical character so as to be amenable to adhesion to the at least one first polymeric substance in the extrusion product. The preferred embodiment of the invention method is conducted under vacuum.

Abstract: A system for shipping product on a vehicle comprising a series of rectangular containment elements surrounding a plurality of products thus together constituting a plurality of units with a T-shaped support positioned between each of the containment elements and thus stabilizing the units and preventing sidewise shifting.

Abstract: An improved flexible joint assembly is disclosed for use in connecting partition members for use in lawn mower drag shields. One of the members includes a receiving groove made of a rigid and heat bondable material. The other partition member includes a resiliently flexible portion which protrudes from a marginal edge thereof. The protruding portion is placed in interfitting heat bonded engagement with the rigid receiving groove so that the latter interfaces and encompassing a substantial area of the protruding portion.

Abstract: Two environmental test zones at different temperatures are separated by an insulated wall. A portion of the wall is rotatable and is designed to hold a test specimen thereon. By rotating this portion of the insulated wall, the specimen is exposed to different temperature zones in recurrent cycles. The two temperature zones are readily separable for ease in removing and installing test specimens.
