  • Patent number: 6715250
    Abstract: A plastic panel for attachment to an exterior wall of a building includes a body, an attachment hem attached to the body and defining at least one aperture for a fastener, and a side flange extending laterally outwardly of the body. The side flange defines a fastening slot for attaching the panel to a building wall. The fastening slot extends at a predetermined acute angle relative to horizontal, preferably about 10-20° relative to horizontal, and about 15° in a particularly preferred embodiment. The fastening slot is preferably elongated and narrow so that the head of a metal fastener extends over opposed upper and lower edges of the slot.
    Type: Grant

  • Patent number: 6421975
    Abstract: A molded plastic panel for covering an exterior building wall includes a laterally directed lead fin, a laterally extending groove below the lead fin, and a rearwardly directed middle wall between rows of simulated shingles, all for joining laterally adjacent panels. A side flange extending outwardly of the panel may also be included. The molded plastic panel preferably also includes at least one row of simulated shingles separated by a plurality of gaps each having a randomly varying width in order to camouflage spacings between adjacent panels that change because of thermal contraction and expansion. In a particularly preferred embodiment, the panel body includes a locking tab and a folding flange. The folding flange includes a locking lip for engaging a locking tab on an adjacent panel and a flexible hinge connecting the locking lip to the panel body. The flexible hinge allows the folding flange to be disconnected from the locking tab when replacing a single panel.

  • Patent number: 5762810
    Abstract: A coalescing oil/water separator for removing free and dispersed oil from a wastewater stream with increased separation efficiency and producing a substantially oil-free effluent. The coalescing oil/water separator is self-contained in a tank shell and includes an improved oil coalescing medium for separating oil out of wastewater and a series of baffles and weirs to direct flow, skim the separated oil and control the liquid level in the separator. The improved oil coalescing medium is uniquely designed and sized to maximize the coalescing surface area in and the flow rate through a given volume of medium by including a plurality of molded, stackable perforated sheets or plates having an oleophilic surface and increased coalescing surface area for inducing impingement of oil droplets on the medium surface.

  • Patent number: 5728171
    Abstract: A composite and metal prosthetic component has a metal pyramid insert. The insert part includes a pyramid part and a stem having at least one slot in its bottom. Composite material may fill the spot to prevent rotation of the stem within the composite base. An annular, part spherical aluminum dome is molded onto the composite part at a position to act as a contact surface for parts mating with the pyramid part.
