  • Publication number: 20080141898
    Abstract: Improved mopping grade asphalt compositions and methods of preparing them. Methods according to the invention include mixing asphalt with a gelling agent such as attapulgite or other clay and with thixotropic agents such as synthetic or organic fillers, and optionally with one or more of ether amine or other surfactants. Thixotropic agents may for example include cellulose fibers, polyolefin fibers, and mineral wool. The asphalt compositions are mixed in a shearing mixer at a temperature high enough to provide substantially uniform dispersion of each of the mixed ingredients in the completed composition. Inventive compositions provide viscosities suitable for application at 200-350 degrees Fahrenheit or lower, excellent adhesion, and superior sag resistance.

  • Publication number: 20030183955
    Abstract: A flow through humidifier is disclosed having a water distribution tray disposed above an evaporator pad. A drip nozzle is connected with the outlet of a water supply tube and delivers discrete water drops to said water distribution tray. The drip nozzle may be located outside or inside the tray. A humidifier housing is connected with an inlet air duct which extends between a first furnace air duct and the housing and the housing outlet air duct connects with a second furnace air duct. An adjustable damperer is disposed in one of the humidifier housing air ducts for restricting air flow through the evaporator pad. In a second embodiment, water is supplied to the drip tray under control of a float valve which is actuated by a float posed in a water collection reservoir.

  • Patent number: 6306937
    Abstract: Fully oxidized cutback asphalts suitable for application in roofing, waterproofing, and sealing applications in all weather conditions, including as mastics and other sealants. Compositions according to the invention comprise unprecedented proportions of solids and asphalts yet remain workable to temperatures as low as 20° F. or below. In addition to fully-oxidized roofing-grade asphalts, preferred compositions according to the invention also comprise hydrophobic agents selected from the group comprising fatty acids and amine compounds and may be applied in rain or other wet conditions, and include polybutene or fatty acid peptizers to control the glass transition temperature of the completed mastic and thereby permit application of the composition at extremely low temperatures. Preferred embodiments optionally also comprise fillers such as cellulose fibers, diatomaceous earth, limestone, and asbestos for various advantageous purposes.

  • Patent number: 6287672
    Abstract: A bright metallized laminate is disclosed that includes a polyvinylidene difluoride-acrylic film having microscopically smooth surfaces, a discontinuous layer of indium islands deposited on the polyvinylidene difluoride-acrylic film, an adhesive layer bonded to the surface of the discontinuous indium layer opposite the polyvinylidene difluoride-acrylic film, and a thermoplastic backing layer bonded to the adhesive layer opposite the discontinuous layer of indium islands. An associated method is disclosed for forming the bright metallized laminate that includes the steps of casting a polyvinylidene difluoride-acrylic film to a polymeric substrate, depositing a discontinuous layer of indium islands upon the polyvinylidene difluoride-acrylic film, placing a polymeric film onto the discontinuous layer of indium islands, and press polishing the polyvinylidene difluoride-acrylic film and the discontinuous indium layer. The polyvinylidene difluoride-acrylic film demonstrates a roughness average (RA) of about 0.
