Patent number: 5382476Abstract: Cured aminoplast resins are recycled by a process in which said resins, which may contain fillers, are treated with an aqueous sulfite, hydrogen sulfite or disulfite solution and the resulting low molecular weight degradation products are used in chemical processes. The resulting low molecular weight degradation products of cured aminoplast resins are used for coating moldings, for tanning leather and skins and for the production of moldings which contain cured aminoplast resins or consist thereof.Type: GrantFiled: May 20, 1994Date of Patent: January 17, 1995Assignee: BASF AktiengesellschaftInventors: Juergen Weiser, Wolfgang Reuther, Erwin Hahn

Patent number: 5376459Abstract: The invention concerns graft copolymers, useful for the treatment of leather, comprising monomers of the formula ##STR1## grafted onto a base polymer comprising monomers of the formula ##STR2## wherein R.sub.1 and R.sub.2 stand for a hydrocarbon group having 2 to 24 carbon atoms, with the proviso that the groups R.sub.1 and R.sub.2 have van der Waals volumes which differ from one another by less than 30 percent.Type: GrantFiled: December 1, 1993Date of Patent: December 27, 1994Assignee: Rohm GmbHInventors: Juergen Christner, Harald Bauer, Maria L. Weber, N'Gueyilb acu/e/ : Victor

Patent number: 5344692Abstract: A flexible laminate, wherein a substrate of leather carries a coating which enhances the appearance and/or the quality of the substrate, is formed between an anvil and a ram in a press. The coating has an inner layer which overlies and fills or nearly fills scratches and/or other unevennesses in one side of the substrate, and an outer layer which overlies the inner layer can be made of a plastic material. The outer layer is first applied to a flexible plastic or paper carrier, and the inner layer is sprayed or otherwise applied to the outer layer before the resulting coating is introduced into or conveyed through the clearance between the anvil and the ram. The exposed surface of the outer layer can be smooth or it can be profiled to imitate the grain of a particular type of leather, such as ostrich leather or alligator leather.Type: GrantFiled: April 8, 1993Date of Patent: September 6, 1994Inventor: Helmuth Schmoock

Patent number: 5316799Abstract: Methods for treating siliceous and carbon central structures with a water repellant composition and a paint are provided. An effective amount of water repellant composition is dispersed in paint or in paint and water, and the mixture then is applied in a continuous process after mixing to the object to be treated.Type: GrantFiled: October 30, 1992Date of Patent: May 31, 1994Assignee: Advanced Chemical Technologies, Inc.Inventors: Dean E. Brunken, Arnulf P. Hagen

Patent number: 5316824Abstract: Building materials such as concrete can be protected from the growth of algae by being treated with a compound containing tin covalently bonded to a silylating group such that cleavage of the covalent bonds due to hydrolysis or photolysis is minimized, thus making the treatment ecologically safe. One such compound is (n-Bu).sub.3 SnCH.sub.2 CH.sub.2 Si(OEt).sub.3. The tin compound can either be incorporated into raw materials from which building materials are to be made, or it can be applied to the finished building materials. When the tin compound is applied to a building material that is algae streaked, the streaking should disappear.Type: GrantFiled: December 16, 1991Date of Patent: May 31, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventors: Billy L. George, Katherine A. Brown-Wensley

Patent number: 5314755Abstract: A concrete surface having at least a residual amount of sodium fluorophosphate. A method to reduce scaling due to freezing and thawing is also disclosed. The method comprises contacting the surface of a concrete with a system containing at least sodium fluorophosphate. The sodium fluorophosphate closes the pores to water and other foreign matter.Type: GrantFiled: October 15, 1992Date of Patent: May 24, 1994Assignee: Domtar, Inc.Inventors: Bernard Malric, Rejean Beaudoin, Chantal Berthelot
