  • Patent number: 9325104
    Abstract: A connector device includes a device body and a pin assembly. The connector device includes a bushing portion with a conductive bus having a first bore, a conductive housing with a second bore that is axially aligned with the first bore, an internal chamber separating the first bore and the second bore, and a gelatinous silicone material enclosed within the internal chamber. The pin assembly includes a non-conductive tip and a conductive pin secured to the non-conductive tip. The pin assembly is configured to move axially, within the first and second bores, between a closed position that provides an electrical connection between the conductive bus and the conductive housing and an open position that provides no electrical connection between the conductive bus and the conductive housing. The gelatinous silicone material inhibits voltage arcing across a surface of the non-conductive tip when the pin assembly is in the open position.

  • Patent number: 8268066
    Abstract: It has been unexpectedly found that the solvent extracted aromatic cut of heavy vacuum gas oil can be oxidized to produce an adhesive composition that has all the needed attributes of a self seal adhesive for asphalt roofing shingles. This self seal adhesive composition offers numerous benefits and advantages over conventional self seal adhesives for roofing applications. For instance, it does not require any volatile organic solvents and is accordingly environmentally friendly. Additionally, it does not contain any asphalt or polymers and will not phase separate and accordingly offers excellent long term stability.

  • Patent number: 7901563
    Abstract: The present invention relates to a method for preparing an industrial asphalt comprising (1) heating an asphalt flux to a temperature which is within the range of about 400° F. (204° C.) to 550° F. (288° C.) to produce a hot asphalt flux, (2) sparging an oxygen containing gas through the hot asphalt flux for a period of time which is sufficient to increase the softening point of the asphalt flux to a value of at least 100° F. (38° C.), to produce an underblown asphalt composition; and (3) mixing a sufficient amount of a polyphosphoric acid throughout the underblown asphalt composition while the underblown asphalt composition is maintained at a temperature which is within the range of 200° F. (93° C.) to 550° F. (288° C.) to attain a softening point which is within the range of 185° F. (85° C.) to 250° F. (121° C.) and a penetration value of at least 15 dmm at 77° F. (25° C.) to produce the industrial asphalt.

  • Patent number: 7900266
    Abstract: It has been unexpectedly found that the solvent extracted aromatic cut of heavy vacuum gas oil can be oxidized to produce an adhesive composition that has all the needed attributes of a self seal adhesive for asphalt roofing shingles. This adhesive composition does not require any volatile organic solvents and is accordingly environmentally friendly. It does not contain any asphalt or polymers and will not phase separate. Thus, it offers excellent long term stability. Additionally, it is made by the simple oxidation of the solvent extracted aromatic cut of heavy vacuum gas oil and is accordingly relatively inexpensive. The subject invention more specifically reveals an asphaltic roofing shingle comprising a back surface and an exposure surface, wherein the back surface is covered with an oxidized solvent extracted aromatic cut of heavy vacuum gas oil.
