Abstract: Disclosed is a system for measuring and controlling the thickness of asphalt roofing materials during manufacturing. Light beams are used to generate a time of flight signal that is used to determine the thickness of the asphalt roofing layer. A controller generates a thickness control signal that controls a coater to modify parameters of the coater to produce the asphalt roofing layer with a desired thickness.
Abstract: A deck board support bracket includes a drainage channel in a top surface of the bracket and deck boards are secured in an end to end manner with a space between two deck board ends centered over the drainage channel. Water presented on the deck surface at two deck board ends passes therebetween and to one side of a supporting joist. The deck board support bracket can be used with various deck board fastening arrangements and preferably is made of an injection molded plastic material.
Abstract: The present invention is directed to an aqueous-based fire inhibitor formulation comprising potassium salts and high nitrogen-based constituents encapsulated with a binder. The formulation contains no halogenated or toxic materials and is considered safe around adult humans and animals. The solvent is water-based and the dry state of the formulation emits virtually zero volatile organic compounds.
Abstract: A top mounted column placement element includes a plumb bob hanging element to allow a plumb bob to hang from the top mounted column placement element and identify a corresponding portion of a bottom mounted column placement element. The top mounted column placement element defines a column perimeter. The bottom mounted column placement element also defines a column perimeter. Once the top mounted column placement portion and bottom mounted column placement element are in place, the column can be placed and set to conform to both defined column perimeters, ensuring the column is properly positioned.
Abstract: Disclosed are asphalts that are suitable for making shingles and other roofing material, i.e., coating asphalts, from harder paving asphalts, without oxidation of the paving asphalts. This is achieved by using various additives, including polyethylene waxes, low density and high density polyethylene materials, hard paraffin polyethylene, Sasol waxes, that are made using the Fischer-Tropsch process, and thermoplastic polyolefins that reduce brittleness at cold temperatures.
