  • Patent number: 5352313
    Abstract: In a method of transporting vehicle windows and sealant, the sealant is preferably inserted into a sealant groove formed in a carrier. The carrier thus forms both a mold for forming the sealant and a transport device. The sealant groove includes a release agent such that the sealant easily leaves the groove. The carriers have structure such that they may be stacked in a first orientation wherein a relatively great spacing is provided between the carriers. The carriers are stacked in this orientation when a window and/or sealant is received on the carriers. After the windows and sealant have been removed from the carriers, the carriers are restacked in a second orientation wherein the distance between adjacent stacked carriers is substantially smaller. This orientation is used when the carriers are returned for re-use.

  • Patent number: 5350472
    Abstract: A novel method and apparatus are provided for making an improved welded joint between overlapping lengths of thermoplastic strap. The welded joint includes a central region and an adjacent peripheral region. The pressure on the strap joint during formation is released first in the peripheral region and subsequently in the central region. An embodiment of the apparatus for making such a joint includes an anvil, a central strap-engaging member, a peripheral strap engaging member, and a mechanism for moving the anvil sequentially to three positions. At a first position the overlapping strap lengths are pressed between the anvil and both the central and peripheral strap-engaging members. In the second position of the anvil the peripheral strap-engaging member does not press against the strap lengths while the central strap-engaging member continues to press the strap lengths against the anvil.

  • Patent number: 5350473
    Abstract: A cover forming apparatus for forming a flower pot or flower pot cover from a sheet of material by engaging a sheet of material about the outer surface of a mold, die or pot. The cover forming apparatus includes a plurality of pivotable forming members resting in a surface which supports a sheet of material upon which is positioned a flower pot mold or flower pot. When the forming members are pivotally moved from the storage position to an extended position, the forming members cause the sheet of material to be appressed to or engaged with the mold or pot. The article formed in accordance with the present invention may be separable from the mold or pot and usable as a flower pot or flower pot cover or may be more or less securely attached to the pot by adhesive, cohesive, barbs, friction pinches or other securing means thereby forming a decorative cover connected to a flower pot.

  • Patent number: RE34701
    Abstract: A magnetically detectable plastic, e.g., polyethylene, polyvinyl, etc., pipe for underground use comprises a hollow tubular plastic pipe having particles of magnetic material embedded in plastic and secured integrally with the wall of the pipe. The magnetic particles are of iron oxide or barium ferrite and of a size, shape, distribution and proportion such that the plastic pipe may be easily detected by magnetic detection apparatus on the surface when the plastic pipe is buried at a selected depth under the ground. The magnetic particles are uniformly distributed throughout the thickness and uniformly distributed around the entire circumference of the plastic pipe or the magnetic particles may be distributed in discrete portions of the plastic pipe, as for example, a uniform outer layer of the pipe or in stripes or strips extending along the pipe.
