Patent number: 5725723Abstract: In an apparatus for forming pipe insulation discrete panels of generally rigid planar board insulation are fed through a sizing apparatus to control thickness, then fed into a vertically oriented conveyor where adjacent ends of the panels are adhered to one another to form a continuum of panels passing through the conveyor. A horizontally moving severing station cuts the panels into transverse trapezoidal segments, such that each succeeding segment is reversed relative to the adjacent segments with the severing plane being common. A tipping mechanism tips the segments according to their orientation such that all of the segments are received on a horizontal conveyor in the same orientation. An accumulator conveyor abuts the base of each segment against each adjacent segment such that a solid surface is formed for the application a backing to integrate the trapezoidal segments. Alternatively, the panels are sized and end glued on a horizontal conveyor prior to forming a series of trapezoidal segments.Type: GrantFiled: May 20, 1996Date of Patent: March 10, 1998Assignee: Mineral Products & Technology, Inc.Inventors: George C.

Patent number: 5098624Abstract: Fiber reinforced thermoplastic molded products, sheets, and the like, having a glossy surface are produced by intimately blending discrete reinforcing fibers (e.g. fiberglass) and thermoplastic fibers (e.g. polypropylene or polycarbonate) into a web. The web is heated to the melting point of the thermoplastic fibers while applying pressure, to eliminate air and press the web into a consolidated structure. Breakage of the reinforcing fibers is minimized by limiting the thickness of the web and limiting the pressure so as to produce a consolidated structure with minimal fiber breakage and a Notched Izod of at least one. Layered consolidated structures, some without reinforcing fibers, may be heated and pressed together to form a final structure having a thickness greater than the individual structures. The great majority of the fibers are provided so that the fibers of each type are within the range of about 0.5-5 inches.Type: GrantFiled: October 31, 1990Date of Patent: March 24, 1992Assignee: C.H.

Patent number: 4217327Abstract: Plastic films or sheets having tear lines formed therein are disclosed. These films are made by forming a score along a predetermined line in the surface of a plastic film to form a tear line and then restoring the scored film surface without eliminating the line of tear. The products tear very easily along predetermined lines even though the restored plastic films have enhanced impact strengths. By restoring the surface of the scored film, score lines become invisible to the naked eye and the useful life of the film is extended. Single-ply or multi-ply products are disclosed including products having an embossed or textutred surface, still without eliminating the capability for a smooth line of tear. The products have many utilities as structural materials which may be sized or torn by hand, including wall coverings, window shade coverings, rupturable packages and envelopes, to mention a few.Type: GrantFiled: March 27, 1978Date of Patent: August 12, 1980Assignee: Clopay CorporationInventors: Leo V.

Patent number: 4157562Abstract: A gate-controlled bidirectional switching device has two main terminals on opposite major surfaces of the device. A single gate terminal located adjacent one of the main terminals on one of the major surfaces receives a signal biased with respect to said one terminal to trigger the device into conduction. The device conducts current in either direction through the main terminals, depending on the polarity of an applied bias potential across the main terminals. By controlling the resistivities or the widths of two base regions in the device with respect to each other, a trigger current for switching the device from a nonconductive state to conduct current in the one direction is adjusted with respect to that required to switch the device to conduct current in the other direction.Type: GrantFiled: October 13, 1977Date of Patent: June 5, 1979Assignees: Western Electric Company, Inc., Bell Telephone Laboratories, IncorporatedInventors: Frederick A.
