  • Patent number: 7717988
    Abstract: A fire resistive coating made Lassenite N Pozzolan and a water based paint. The Lassenite N Pozzolan is present in a range from about 20% by weight of the composition to about 80% by weight of the composition. The water-based paint present in the range from substantially 20% by weight of the composition to substantially 80% by weight of the composition.
    Type: Grant

  • Patent number: 7416589
    Abstract: An air-droppable wildfire retardant composition including Lassenite N pozzolan is a natural siliceous (amorphous) mineral, consisting of the layers of diatoms and volcanic tuffs of Northern California's Cascade Range. The Lassenite pozzolan is mixed with a thickener such as Bentonite clay, a measured volume of water forming a slurr-type mixture capable of suspending the particles of pozzolan in a mixture having a viscosity sufficient to avoid solids separation. The inventive fire retardant contains substantially three innocuous ingredients which have no harmful effects to the atmosphere, plant, or animal life.

  • Patent number: 5567248
    Abstract: A contact arrangement for permitting a plurality of solar cells to be electrically interconnected. The inventive device includes a solar cell having orthogonally oriented outer peripheral edges and oblique angled corner edges. A first pair of negative contacts is secured to a top surface of the cell proximal to a first adjacent pair of angled corner edges, and a second pair of negative contacts is secured to the cell proximal to a second adjacent pair of angled corner edges. A pair of positive contacts is secured to the top surface of the cell proximal to the second adjacent pair of angled corner edges and extends at least partially around the second pair of negative contacts. An elongated positive buss bar extends between the pair of positive contacts and along the top surface of the cell proximal to one of the outer peripheral edges.
