Patent number: 11739312Abstract: In one aspect, the invention is directed to polypeptides having an amylase and/or glucoamylase activity, polynucleotides encoding the polypeptides, and methods for making and using these polynucleotides and polypeptides. In one aspect, the polypeptides of the invention can be used as amylases, for example, alpha amylases, to catalyze the hydrolysis of polysaccharide, oligosaccharide or starch into sugars. In one aspect, the invention provides delayed release compositions comprising an desired ingredient coated by a latex polymer coating. In alternative embodiments, enzymes are used to make biofuels, e.g., ethanol, butanol, propanol, or a gasoline-ethanol mix, including a bioethanol, biopropanol, biobutanol, or a biodiesel, or for any form of fuel or biomass processing.Type: GrantFiled: December 2, 2020Date of Patent: August 29, 2023Assignees: BASF Enzymes LLC, Syngenta Participations AGInventors: Malgorzata Slupska, Geoff Hazlewood, Cathy Chang, Peter Luginbuhl, Ellen Burke, Michelle Cayouette, Uvini Gunawardena, Majid Ghassemian, Aron Silverstone, Yan Zhang

Publication number: 20030121095Abstract: A bathing chair is provided that swivels on a fixed base and includes a leg support assembly. The combination of the leg support and the swiveling action of the chair allows a disabled or handicapped bather to comfortably enter and/or exit a bathtub or a shower stall without the aid of another person. The leg support also allows the legs of the bather to clear obstacles, such as the ledge of a bathtub or the lip of a shower stall, without the aid of another person. The bathing chair also includes a single support assembly that is capable of supporting the bathing chair and a bather without the need for any additional support structures. The need for only a single support assembly to adequately support the chair provides a bathing chair that is sturdy, lightweight and simple to install.Type: ApplicationFiled: December 17, 2002Publication date: July 3, 2003Inventors: Dyan Argento, Jeff Baldasare, Brian Borra, Sean Brennan, Cathy Chang, Derek Conner, Jim Crowell, Jon Faisant, Barry Hartzberg, Paul Hauge, Nathanael Heins, Ben Klaber, Carrie Kuenzig, Jason Listak, Alissa May, Chris Morgan, Cam Richardson, Jeff Storer, Ben Trotter, Adam Viccaro, Erin Williams
