Abstract: A slat apparatus for use with a chain link fence for providing privacy, wind protection and/or decoration includes a plurality of slat members for positioning in slat receiving channels formed by linking wires of the fence. Each slat member includes a substantially rigid elongated hollow body member having curved side members, at least a pair of curved longitudinal ribs therein and a pair of flexible and resilient wing portions positioned on opposite sides thereof. The ribs in the rigid elongated body member prevents crimping of the fence slat when installed in a chain link fence.

Abstract: A method and apparatus for making U-shaped retaining wall members includes a combination of an extrusion die station, a calibration station, a heavy duty puller such as a tire puller and a travelling saw. The calibration station includes a series of calibration blocks which are spaced apart in an increasing fashion and controllably cooled to subject the extruded product exiting the extruding station to a controlled temperature gradient to prevent thermal shock.

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: Slat apparatus for use with a chain link fence for providing privacy, wind protection and/or decoration, including a plurality of slat members for positioning in slat receiving channels formed by the linking wires of the fence such that substantially no space remains between adjacent slats. Each slat member includes a substantially rigid elongated body member and a pair of flexible and resilient wing portions positioned on opposite sides thereof. The combined width of the wing portions is approximately equal to or greater than the width of the body member to enable easy installation of the slats and to provide complete privacy in a neat and uniform manner. The slat apparatus preferably is formed by co-extrusion of a substantially rigid plastic material for the body member and a flexible and resilient plastic material for the wing portions.

Abstract: A scented pole cover for covering closet poles, shower curtain poles or the like is disclosed. The pole cover is an elongate, hollow object having a slit along the entire length thereof. In operation, the slit is expanded to fit over a pole and the pole cover snaps into snug engagement about the pole. Also disclosed are extrusion methods for fabricating the pole cover of the invention.

Abstract: Slat apparatus for a chain link fence, comprising a plurality of substantially parallel slats extending through the fence wires. Each slat has laterally extending wing portions positioned closely adjacent to the wing portions of adjoining slats to provide privacy by leaving only small spaces between the slats. The slats have apertures extending laterally therethrough rearwardly of the wing portions. The slat apertures are laterally aligned and a flexible belt extends through the apertures to retain the slats in parallel relation on the fence. The wing portions are of less thickness than the slats.

Abstract: The present invention provides a process for hermetically sealing a container having an open top. The process of this invention employs a novel cap liner comprising a backing layer consisting of thermoplastic material, a sealing layer and a bond layer between the backing layer and the sealing layer. The process comprises the steps of: providing a cap adapted to engage the open top of a container; providing a novel cap liner of this invention; inserting the cap liner into the cap; securing the cap to the container such that the sealing layer of the cap liner contacts the container and extends across the open top of the container; and bonding the sealing layer of the cap liner to the container to produce a hermetically sealed container.

Abstract: A cap brim or the like, comprising outer fabric layers joined to an intermediate backing by stitching. The backing comprises a middle layer of a foamed thermoplastic material, and outer layers of solid thermoplastic material bonded to both sides of the middle foamed layer. The outer solid layers serve as wipers to prevent the breaking off of pieces of the middle foamed layer when the outer fabric layers are stitched to the backing.

Abstract: This invention relates to a method for a manufacture of plastic sandwich element in which a first extruder is charged with essential ingredients for productions of foamed cellular plastic at a predetermined temperature. A second extruder is charged with essential ingredients for production of solid plastic at a temperature of at least 25 degrees Farenheit below the predetermined temperature. The resulting sandwich is extruded through an extrusion die forming an integral plastic sandwich with the heat of the foamed plastic layer causing a partial melting.
