Patent number: 4600728Abstract: Elastomer compositions are provided which contain high molecular weight water-insoluble humic acid humates. The compositions show improved bloom resistance in both the uncured and the vulcanized or otherwise cured state. Methods to make sponge rubber are also disclosed in which the humic acid humate is the gas producing agent. A predominantly humic acid humate containing composition maintains a clean mold, and curing an uncured article coated with the humate at elevated temperature will clean metal molds which have dirty surfaces, particularly when green coated articles are vulcanized in contact with the mold's surfaces.Type: GrantFiled: July 24, 1985Date of Patent: July 15, 1986Assignee: Alfred D. Lobo Co., L.P.A.Inventors: Harold R. MacKeighen, Vincent T. Cortesi

Patent number: 4594384Abstract: The present invention relates to an adhesive composition for manufacturing glued laminated beams and wood constructions. One component of the adhesive composition is resorcinol-phenol resin. Resorcinol-phenol adhesives are as such known in the prior art. The main ingredients of these adhesives are resorcinol, formaldehyde and phenol. Among the drawbacks in the use and production of resorcinol-phenol adhesives are their high price and the fact that the raw materials are difficult to obtain. The purpose for employing the adhesive composition of the invention is to eliminate some of the difficulties connected with the availability of the raw materials, particularly resorcinol, and to help produce a new, more economical resorcinol-phenol based adhesive composition.Type: GrantFiled: December 21, 1984Date of Patent: June 10, 1986Assignee: Valtion Teknillinen TutkimuskeskusInventors: Harri Kilpelainen, Pentti Kankaanpaa

Patent number: 4526911Abstract: This invention relates to an improved coating composition for application to aluminum cell cathodes, wherein said composition comprises a Refractory Hard Material, and a thermosetting resinous binder system.The resinous binder system is characterized by a char yield greater than 25 percent, while the coating composition exhibits expansion characteristics such as to adhere to a cathode block at temperatures up to and including those normally encountered in the operation of an aluminum cell. The ablation rate of the carbon system utilized is essentially equal to the combined wear and dissolution rate of the Refractory Hard Material in an aluminum cell environment.Type: GrantFiled: July 22, 1982Date of Patent: July 2, 1985Assignee: Martin Marietta Aluminum Inc.Inventors: Larry G. Boxall, William M. Buchta, Arthur V. Cooke, Dennis C. Nagle, Douglas W. Townsend

Patent number: 4521555Abstract: Plastisols useful for automobile undercoatings, anti-noise compositions, adhesives, sealing compositions and coatings for untreated, pretreated, phosphated, primed and prelacquered metal bases are improved by the addition of coke dust and coal dust fillers. The carbon dust fillers have a particle size of about 0.5 to 1000 microns and they are used in a concentration of about 9 to 90% by weight based on the total weight of plastisol and carbon dust. The carbon dust filled plastisols have a specific gravity of about 1.1 to 1.3.Type: GrantFiled: January 13, 1984Date of Patent: June 4, 1985Assignee: BASF Farben & Fasern AGInventors: Rainer Blum, Max Seitz, Friedrich Kaczinski

Patent number: 4511689Abstract: This invention relates to a blend of an olefin/alkyl acrylate copolymer and hardened extract which has a saturated hydrocarbon content of not more than 10% by weight and articles made therefrom, e.g. linings for reservoirs and for water proofing roofs. The new products are easier to manufacture since they resist gelation, do not suffer from problems of shrinkage and are appreciably cheaper.Type: GrantFiled: December 3, 1982Date of Patent: April 16, 1985Assignee: The British Petroleum Company p.l.c.Inventor: Alan C. G. Aldred
