  • Roof insulation system
    Patent number: 4528790
    Abstract: Insulation supporting tubes are suspended from auxiliary support beams extending transversely of and supported by more widely spaced main support beams. The insulation supporting tubes extend all the way across a bay between adjacent main support beams and are supported by two hangers at opposite ends and by a circular hook at midlength. For clamping at eave struts, a hanger assembly is mounted on each eave strut between each two adjacent insulation strips, the hanger assembly including two independently vertically adjustable axle tubes received respectively in adjacent bushings of two adjacent clamping tubes.

  • Melting furnaces
    Patent number: 4528013
    Abstract: A melting furnace is disclosed which heats by joule effect to supply molten material of uniform temperature at the floor of the melter. During formation of molten material, an essentially isothermal condition across a given horizontal plane of the body of molten material is established. Spaced apart opposed electrodes and controlled current flow establish these uniform temperatures and allow molten material to be formed directly from the melter without further processing.

  • Chemically modified asphalts and glass fibers treated therewith
    Patent number: 4528241
    Abstract: Improved chemically modified asphalts are provided of the type which is the reaction product of asphalt, a vinyl aromatic monomer and a rubbery polymer.
