Patent number: 5527409Abstract: An inexpensive, durable, and easily applied roofing material for commercial establishments prepared from waste and used tires, wherein the tires are shredded into small particle size, and thence uniquely compacted into large log-like article of substantial size and weight, as on the order of 2,000 pound and four feet in length. The logs are cut in a peeling manner to form wound up rolls of thin rubber tire sheeting, which are then cut and laid as roofing. Sealant applied over the roofing ensures waterproofing, enhances ultraviolet ray protection, adds to overall fire resistance, and helps to prevent leakage at the sheeting joints.Type: GrantFiled: March 3, 1995Date of Patent: June 18, 1996Inventor: Robert R. Lanphier

Patent number: 5397524Abstract: A concrete form molding is formed of a molding body of closed cell extruded polystyrene material. The molding body includes at least one molding face comprising an extruded molding face formed in the polystyrene material extrusion process. The concrete form molding may also include one or more cut molding faces that are formed after the material is extruded. Each cut molding face is also made up of substantially all closed polystyrene cells. The apparatus of the invention includes an arrangement for precisely supporting a sheet of closed cell extruded polystyrene material vertically and horizontally with respect to a series of laterally spaced apart forming elements. The apparatus also includes structure for advancing the sheet through the forming elements so that the forming elements make contact with the polystyrene material and melt the material. The molten polystyrene material closes substantially all of the cells intersected by the forming elements to form the cut molding faces.Type: GrantFiled: October 12, 1993Date of Patent: March 14, 1995Assignee: Godonco Industries, Inc.Inventor: Richard M. Phillips

Patent number: 5362435Abstract: A process of molding multi-durometer footwear soles which includes forming elongated components from compression moldable compounds, each component having a different hardness (Shore A). The components are configured and dimensioned such that the softer component will be positioned on top of and within the configuration of the bottom, harder component. The assembled components are placed in a compression mold and covulcanized together.Type: GrantFiled: August 6, 1993Date of Patent: November 8, 1994Assignee: Quabaug CorporationInventor: John F. Volpe

Patent number: 5356573Abstract: A high performance ski base material is made of ultra high molecular weight polyethylene having a molecular weight of at least 500,000. After heating, quenching and light tensioning operations, this material exhibits low crystallinity and high transparency characteristics. Such material is ideal for professional high speed skis because of its excellent wax retention quality. The invented ski base material is ideally suited for product-identity purposes because of its outstanding ability to clearly reveal detailed inscriptions placed on the running surface of a ski board.Type: GrantFiled: November 23, 1992Date of Patent: October 18, 1994Assignee: Yamaha CorporationInventor: Norihiko Kageyama

Patent number: 5035761Abstract: A method for preparing cross-sections of yarn samples along the plane perpendicular to the yarn's longitudinal axis is disclosed. This method involves the steps of passing the yarn through a hollow capsule so that the axes of the yarn and the capsule are aligned in parallel, tensioning the yarn to remove any crimp, forming a solid stub inside the capsule to fix the position of the tensioned yarn, and then cross-sectioning the stub perpendicular to its longitudinal axis.Type: GrantFiled: November 30, 1989Date of Patent: July 30, 1991Assignee: E.

Patent number: 4893424Abstract: An identification marker (17) is described for use in permanently identifying an individual histology sample (21), the marker including columnar indicia (18) mounted on a base (19) having a location flange (20). A specially adapted cassette having a slot (16) to receive the identification marker is described together with apparatus and method for moulding the indicia in a protein such as agar agar. The use of the identification marker is described firstly mounted in the cassette (11) during treatment of the sample (21) and later mounted beneath the cassette (11) in the slot (16) for wax embedding of the sample and identification marker. The marker (17) is sectioned simultaneously with the tissue sample (21) by means of a microtome (31), each section taken being identified by a section through the identification marker embedded alongside the sample.Type: GrantFiled: November 9, 1987Date of Patent: January 16, 1990Inventor: William McLean

Patent number: 4850844Abstract: An apparatus for making tapered plastic shingles including a conveyor for moving a block of plastic shingle material along a linear path and at least one heated wire extending transversely across the path to cut the block into two or more tapered shingle slabs. The shingle slabs are thereafter cut to form shingles or slotted to resemble individual shingles of desired widths. One end of the wire is adapted to be adjusted vertically to selectively vary the acute angle of the wire relative to the horizontal plane to thus vary shingle taper. A mechanism is also provided for continuously reciprocating the wire vertically to impart a textured surface to opposed, cut surfaces of the shingle slabs.Type: GrantFiled: September 11, 1987Date of Patent: July 25, 1989Inventor: William E.
