Patent number: 5641815Abstract: In order to be able to produce formed elements or building elements with a significantly increased strength with a building material or structural material, it is suggested to provide the material with a largely uniform fine pore structure or a microcellular structure. These fine pores preferably have a diameter in the range of approx. 0.01.mu. to approx. 5.mu. and are self-contained. The material contains a reactive binding agent or a reactive matrix material, which can be a cement/water mixture or also a synthetic resin, for example polyurethane, epoxy resin, etc.Type: GrantFiled: October 11, 1994Date of Patent: June 24, 1997Inventor: Hans Beat Fehlmann

Patent number: 5318837Abstract: Soundproofing materials consisting essentially of zinc oxide whisker particles having a nucleus body and needle crystal portions extending radially from the central body in different plural directions. The materials may comprise a support material for supporting the zinc oxide whisker particles. Such support materials include inorganic materials such as metals, ceramics, glasses, cements, mortars and various fillers in the form of powder, flakes, fibers and the like, and organic materials such as resins, rubbers, waxes and the like. These materials are particularly suitable for sound insulation, sound proofing, vibration damping and vibration insulation.Type: GrantFiled: December 17, 1991Date of Patent: June 7, 1994Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Minoru Yoshinaka, Eizo Asakura, Mitsumasa Oku, Takeshi Hamabe, Motoi Kitano

Patent number: 5250578Abstract: A foamed cellular cementitious composition useful for sound absorbing, thermal insulation and fire proofing is described. The cementitious composition is produced utilizing a mineral cement, an aggregate, water, and a stabilized foaming composition which includes at least one water-soluble film forming agent, and at least one foaming agent. The stabilized foaming composition provides air to the cementitious composition in an amount substantially in excess of that used in conventional air entrainment of cements. The film forming agent is preferably a resin emulsion and the foaming agent is preferably a nonionic surfactant, anionic surfactant or mixture thereof. The cementitious compositions have a density which is substantially lower than the density of a composition composed of mineral cement and aggregate per se.Type: GrantFiled: July 5, 1991Date of Patent: October 5, 1993Inventor: Charles E. Cornwell

Patent number: 5059637Abstract: A water-base endothermic fire protective material comprising a heat curable thermosetting resin, inorganic fibers, an endothermic inorganic filler, and thermoplastic binder resin is disclosed. The material can vary in viscosity from a putty that is moldable or trowelable into place to a thin paste that can be sprayed to form a flexible and stable fire stop seal or coating. The material with essentially no shrinkage retains strength and adhesion qualities before and after exposure to fire and retains superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire.Type: GrantFiled: May 16, 1991Date of Patent: October 22, 1991Assignee: Minnesota Mining and Manufacturing CompanyInventor: Roger L. Langer

Patent number: 4952620Abstract: Sterically hindered cyclic amines which are substituted by a photoactivatable acyl group at the basic nitrogen atom can be deacylated by irradiation with UV light. This is advantageous if the basicity of the amines proves troublesome during application. Examples of such photoactivatable acyl groups are phenylglyoxyl, phenylacetyl or naphthylacetyl groups.Type: GrantFiled: August 12, 1988Date of Patent: August 28, 1990Assignee: Ciba-Geigy CorporationInventors: Godwin Berner, Mario Slongo

Patent number: 4947611Abstract: A wall board structure is formed of one of pulverized straw, pulverized chaff and pulverized palm material having a maximum dimension of from 1 to 3 mm. The pulverized material is mixed with a substantially equal quantity of clay. A fibrous material is added to the mixture, the fibrous material including one or more of palm material fibers, hemp fibers and shredded straw, the fibrous material having a length of from 3 to 5 cm. The mixture of pulverized material and clay and the added fibrous material is poured into a form and then dried. The form preferably includes means for forming one of recesses and through holes in the poured mixture.Type: GrantFiled: January 23, 1989Date of Patent: August 14, 1990Inventor: Michio Otsuka
