Patent number: 6709763Abstract: Articles produced from hydrophobic polymers (e.g., polyethylene) are surface-coated with thin films of starch in order to render the surfaces hydrophilic. The thin coatings form on the surfaces of plastic objects when the objects are placed in contact with hot, aqueous solutions of starch. These starch coatings are extremely adherent to the hydrophobic plastic surfaces under both wet and dry conditions, and they permit the surfaces to be uniformly wet with water. Resultant products have improved biocompatibility, improved compatibility with hydrophilic reagents, reduced build-up of electrostatic charge, reduced blocking, reduced friction, improved absorption of water-based dyes, and improved adhesion properties. The starch coatings are non-toxic, inexpensive and biodegradable.Type: GrantFiled: November 20, 2001Date of Patent: March 23, 2004Assignee: The United States of America as represented by the Secretary of AgricultureInventors: George F.

In order to produce the cellulose acylate film, the solution is applied on a dope band moving in a direction, and dried to contain the solvent between 10-80 wt. % to the cellulose acylate. Thus a film-like material is formed from the solution, and peeled from the dope band. Thereafter the film-like material is further dried to form the cellulose acylate film containing the solvent at between 0.1 and 0.6 wt. %.Type: ApplicationFiled: July 26, 2002Publication date: February 6, 2003Inventor: Yukihiro Katai

Patent number: 6500562Abstract: An electrophotographic transfer sheet having a coating layer on at least one surface base material made of pulp fibers as a main body provided. The elongation of the sheet in the cross direction when the humidity is changed from 25% RN to 90% RH at 20° C. is not higher than about 0.65% and the water content of the sheet at opening its package as measured according to JIS P8127 is approximately in the range from 3.5 to 6.5%. A method of forming a color image using color toners each containing a polyester resin having Mn in the range of from about 1,000 to 9,000 and using the above-described electrophotographic transfer sheet is also provided.Type: GrantFiled: May 18, 2000Date of Patent: December 31, 2002Assignee: Fuji Xerox Co., Ltd.Inventors: Kiyoshi Hosoi, Ryosuke Nakanishi, Tomofumi Tokiyoshi, Masaru Kato

Patent number: 6495248Abstract: A substantially flexible, shape-sustaining cover having a cloth-appearing finish on a surface thereof, the substantially flexible, shape-sustaining cover formed from a flexible, substantially non-shape sustaining laminated material having at least one surface with a cloth-like texture or appearance. The substantially flexible, shape-sustaining cover has a closed lower end, an open upper end with an opening extending therethrough and a decorative border extending outwardly from the open upper end thereof. The substantially flexible, shape-sustaining cover has a plurality of overlapping folds of which at least a portion are permanently connected so that the substantially flexible, shape-sustaining cover may be substantially flattened and then unflattened to assume the original shape of the substantially flexible, shape-sustaining cover.Type: GrantFiled: February 14, 2000Date of Patent: December 17, 2002Assignee: Southpac Trust International, Inc.Inventor: Donald E. Weder

Publication number: 20020123538Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic, or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.Type: ApplicationFiled: August 31, 2001Publication date: September 5, 2002Inventors: Peiguang Zhou, Timothy James Blenke
