Patent number: 9994733Abstract: The invention relates to a method for coating surfaces by enzymatic reaction of a biopolymer, wherein the method comprises the following steps: a) applying an enzyme to the surface of a substrate, and b) contacting the enzyme with the biopolymer to be deposited, wherein the enzyme cleaves the biopolymer, wherein the cleavage gives rise to at least two cleavage products of the biopolymer having different solubility in a solvent, and at least one cleavage product of the biopolymer having relatively low solubility is deposited on the surface of the substrate, and to a coated article obtainable by the method and to a coating composition comprising a biopolymer and at least one component selected from the group comprising binders, fillers, pigments and/or additives, and optionally a solvent.Type: GrantFiled: March 31, 2015Date of Patent: June 12, 2018Assignee: Universität PaderbornInventors: Oliver Ingolf Strube, Wolfgang Bremser, Arne Alexander Rüdiger

Publication number: 20130206034Abstract: A dried distiller soluble based biopolymer, processes for forming the biopolymer, and articles of manufacture thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities and is comprised in part of water-soluble proteins. A biopolymer consists essentially of dried distillers solubles, and an article of manufacture includes a biopolymer consisting of dried distillers solubles and an optional additive. The process of forming dried distiller solubles involves separating whole stillage into a liquid fraction and a solid fraction, wherein the liquid fraction comprises water soluble proteins in an amount greater than the solid fraction, and wherein the solid fraction has a higher solid content than the liquid fraction. The liquid fraction is sprayed at an elevated temperature to remove at least a portion of moisture in the liquid fraction and form particles and granules of the liquid fraction.Type: ApplicationFiled: February 15, 2013Publication date: August 15, 2013Applicant: GS CLEANTECH CORPORATIONInventor: GS CLEANTECH CORPORATION

Publication number: 20130108364Abstract: A method and material for paving a surface, such as a dirt trail, is disclosed. The method includes obtaining raw chert material which is composed primarily of particles of gravel, sand, and clay obtained from a quarry or mine, and which has been screened to remove particles of a size of one inch or more. The screened chert is mixed to achieve consistency of the material, then mixed with a predetermined quantity of an aqueous enzyme solution. The aqueous enzyme solution contains an enzyme fluid mixed with water in the ratio of 0.02 to 5 gallons of enzyme fluid to 400 to 1000 gallons of water. The material-solution mix is than applied to a surface in layers and compacted to achieve a finished thickness of about 6 to 10 inches. After a delay of 48 hours, the paved surface is usable by equipment and vehicles.Type: ApplicationFiled: August 6, 2012Publication date: May 2, 2013Inventor: Barth Campbell

Patent number: 8425728Abstract: Disclosed is a print medium for high speed, digital inkjet printing, which has high brightness and is resistant to yellowing. The print medium includes a base paper formed from a fiber furnish containing at least 30% by weight of mechanical pulp, and a coating layer formed on at least one surface of the base paper. The coating layer contains a metallic salt, a combination of two different binders at a predetermined ratio, and at least one inorganic pigment. A method of making the print medium is also disclosed.Type: GrantFiled: July 17, 2009Date of Patent: April 23, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Xiaoqi Zhou, Xulong Fu, Dave Edmondson

Patent number: 7833915Abstract: In order to provide grease, oil and wax resistance to a paper substrate, a coating containing a binder, a filler material and calcium carbonate is used. The coating of the invention is essentially free from fluorocarbons, which are considered harmful to human and animal populations, and surfactants and other chemicals which may alter the color of the coated paper. The coated paper has a GE brightness level between approximately 50 and approximately 90, while providing superior grease, oil and wax resistance.Type: GrantFiled: June 29, 2001Date of Patent: November 16, 2010Assignee: Spectra-Kote CorporationInventor: Charles W. Propst, Jr.
