Patent number: 4534926Abstract: The present invention relates to a nonhydrated bentonite intimately contacted with a polypropene, polybutene, or mixtures thereof to provide a formable and shapable non-aqueous bentonite composition particularly useful as a water barrier. The bentonite composition can be extruded in the form of a rope, rod, sheet or the like and is sufficiently tacky for adherence to a wall or conduit, floor or roof in areas of potential water flow to prevent the seepage of water through the bentonite composition. In one embodiment, the bentonite composition includes a polypropene and a polybutene and an elastomer, such as butyl rubber, having sufficient resilience to stretch or expand with the expanding bentonite upon hydration and to aid in maintaining the structural integrity and cohesiveness of the composition. In another embodiment, the composition comprises bentonite, an elastomer, and any plasticizer compatible with the elastomer.Type: GrantFiled: April 27, 1984Date of Patent: August 13, 1985Assignee: American Colloid CompanyInventor: Todd D. Harriett

Patent number: 4522735Abstract: Amines are reacted with phosphorous trichloride to form N-dichlorophosphinoamines that are then reacted with a bisphenol in about equimolar amounts to provide polyphosphoramidite oligomers. The polyphosphoramidite oligomers are effective as stabilizers for polymers such as polyolefins, and form even more efficient stabilizer combinations with hydroxyphenylalkyleneyl isocyanurates.Type: GrantFiled: June 17, 1983Date of Patent: June 11, 1985Assignee: The B. F. Goodrich CompanyInventor: Dwight W. Chasar

Patent number: 4459166Abstract: A silver metallizing paste for attachment of silicon semi-conductive devices in lead-frame packages, specifically ceramic packages, which is less expensive than a gold preform but useable in hermetic packages, and provides better electrical and thermal conductivity, and higher bond strength, than silver polyimides. From 25 to 95% of silver is blended with a low-melting glass, preferably one having 95-96% PbO, and a paste or ink is formed with a suitable vehicle at 75-85% solids. Use of the paste follows conventional practice. Selection of Ag:glass ratio depends on the type of die bonding to be used. The paste is particularly useful in MOS technology, where low contact resistance is required, and also finds applications as a solder substitute and bonding chip capacitors. It is most advantageous in attachment of larger-area integrated circuits in that stress cracking associated with the gold-silicon eutectic is avoided.Type: GrantFiled: May 16, 1983Date of Patent: July 10, 1984Assignee: Johnson Matthey Inc.Inventors: Raymond L. Dietz, Michael Featherby, Peter K. Margetts

Patent number: 4404239Abstract: Water repellent treating compositions are based upon olefin and paraffin materials containing a substantial proportion of compounds containing from 20 to 24 carbon atoms. The treating compositions are especially useful for application to wood. Additives such as wood preservatives, alkyd resins and, in especially preferred compositions, organic ionizable compounds are included. The preferred compositions are useful for application to wood substrates which are subsequently electrostatically sprayed with a topcoating.Type: GrantFiled: August 2, 1982Date of Patent: September 13, 1983Assignee: PPG Industries, Inc.Inventor: John F. Grunewalder

Patent number: RE33760Abstract: A pipe thread sealant paste composition comprising from about 30 to about 80 percent by weight of natural flake graphite particles of a size sufficient to pass through a 100 Tyler mesh sieve and a liquid carrier comprising a mixture of mineral oil and petrolatum. The paste composition preferably having a total ash content of no greater than about 1 percent by weight and containing leachable chlorides in amounts equal to or less than about 50 parts per million. The invention also relates to a method for preparing and applying the pipe thread sealant paste to pipe joints.Type: GrantFiled: September 28, 1990Date of Patent: December 3, 1991Assignee: Ucar Carbon Technology CorporationInventor: Ronald A.
