Abstract: A method of welding a thermoplastic sheet, having a first side and a second side, into a cylinder, the method comprising the steps of folding the thermoplastic sheet into a cylinder such that the first side and the second side overlap, positioning the thermoplastic sheet in a cylinder tube having a longitudinal opening such that the overlapping portions of the first and second sides of the thermoplastic sheet are aligned with the longitudinal opening, and activating a heat welder so that a press of the heat welder moves into the longitudinal opening of the cylinder tube and presses the thermoplastic sheet against an opposing surface to weld the overlapping portions of the first and second sides.

Abstract: A motor vehicle and methods are presented in which side facing laser scanner sensors are used to detect road profile conditions and road obstructions in adjacent lanes and the profile information is used to update a central database for active suspension control in vehicles subsequently traveling along the scanned roadway.

Abstract: A multi-layer closure liner for carbonated beverage containers and the like, including a gas barrier layer, a first tie layer on an upper surface of the gas barrier layer, a second tie layer on a lower surface of the gas barrier layer, a first polyolefinic resin layer on the upper surface of the first tie layer, and a second polyolefinic layer on the lower surface of the second tie layer. In the preferred embodiment, the gas barrier layer is ethylene vinyl alcohol copolymer (EVOH), the first and second tie layers are functionalized polyolefin and the first and second polyolefinic resin layers are ethylene vinyl acetate (EVA). The layers defining the closure liner are preferably simultaneously formed using a co-extrusion process to prevent the gas barrier layer from being exposed to moisture.

Abstract: A separating closure liner comprises a laminate construction of a reusable liner portion and an inner seal portion, each separated by a light tack shearable adhesive. The light tack shearable adhesive enables the reusable liner portion to break away from the inner seal portion after it has been sealed to a container neck. The reusable liner portion remains in the closure of the container for sealing purposes. Use of the light tack shearable adhesive permits the use of polyolefin foamed materials as a reusable liner portion.

Abstract: In order to provide a liner which can be used in place of existing type liners used in a closure for a container, a multiple layer liner sheet is coextruded in a manner wherein the outer layers are skin layers formed of a gas permeable material. These layers enclose a gas barrier layer and a foamed layer which respectively prevent the invasion of oxygen from the ambient atmosphere and remove oxygen from the head space to safeguard the contents of the container. The foamed layer provides the liner with the required resiliency, provides space for the inclusion of an adequate amount of oxygen scavenging material, and also provides a cellular structure which allows the gas molecules the freedom to move and quickly come into contact with the oxygen scavenging material.

Abstract: A cap liner and method for producing a cap liner which is particularly suited for use with a cap employed on a hot filled container. The liner includes a disc having one or more outer layers and an intermediate foamed layer bonded thereto. Preferably, the outer layer is formed of a copolymer of polypropylene and polyethylene. The intermediate layer can include a homogeneous admixture of polypropylene and polyethylene or an admixture of polyethylene, a copolymer of polyethylene and polypropylene and ethylene vinyl acetate. One method for producing the cap liner involves mechanically mixing at room temperature polypropylene and polyethylene to form a desired homogeneous admixture for each layer, and then co-extruding the admixtures at approximately 320.degree.-415.degree. F. to form the bonded outer and intermediate layers. Another method involves extruding the copolymer outer layer to the intermediate layer admixture to form the bonded cap liner.

Abstract: A portable cover apparatus for use in vehicular and outdoor applications where sheltering, such as shading from the sun and other environmental elements is desired. The apparatus includes a flexible cover adequate for the particular environmental covering task at hand, i.e. mesh or closed sheet material, supported by structurally independent mast and base supports. Each independent base support has a horizontal anchoring portion, and a vertically offset mast attachment portion that coacts with a telescoping variable length mast to accommodate various shapes and positioning of the flexible cover. In a preferred embodiment, the cover may be attached to the upper mast ends using hook-ended stretch cords, as a method of compensating for different sizes of objects to be covered as well to absorb stress from wind. The side curtains are detachable from the top cover using mating hook and loop fastening material.
