Patent number: 8118177Abstract: A product including a web and a method of manufacturing such a product. The product may be for use as an industrial absorbent or a thermal or acoustic insulator and includes a web including scrap and/or recycled cellulose, the cellulose being selected from a source of post-industrial cellulose and/or a source of post-consumer cellulose, the cellulose being treated with a fire-retardant, the cellulose being dry before web formation, and opened, individuated bicomponent fibers mixed with the cellulose, at least some of the bicomponent fibers being thermally bonded to at least some of the cellulose.

Publication number: 20100017599Abstract: Methods and system for managing manipulation of digital content stored in a content server. One method includes receiving a first mutating identifier at a content manipulation device. The first mutating identifier includes a first secret key. The method also includes generating a content request for digital content stored in the content server at the content manipulation device, the content request encrypted with the first secret key and including an identifier of the digital content; transmitting the content request to an authenticator over at least one communication link; transmitting access rights from the authenticator to the content manipulation device over at least one communication link; transmitting the digital content from the content server to the content manipulation device; manipulating the digital content at the content manipulation device based on the access rights; and marking the first mutating identifier as used at the authenticator.Type: ApplicationFiled: February 8, 2007Publication date: January 21, 2010Applicant: IMAGINEER SOFTWARE, INC.Inventors: William R. Sellars, Richard Malina, William Cochran

Patent number: 7627933Abstract: A method and device for depositing fibers on a forming wire. In one embodiment, a device includes a fiber reservoir having an inlet, a first outlet configured to pass air or gas, and a second outlet configured to pass fiber. The device also includes a fiber meter configured to move fiber out of the reservoir to a forming head via mechanical action and along substantially the entire width of the forming head. The forming head includes one or more air inlets and one or more agitators to blend and open the fiber received from the fiber meter. The forming head interfaces with a vacuum source that draws air into the forming head through the air inlets, which can be adjusted to affect volume and velocity of air drawn into the forming head.Type: GrantFiled: December 7, 2005Date of Patent: December 8, 2009Assignee: Sellars Absorbent Materials, Inc.Inventors: David Drapela, William R. Sellars

Patent number: 7376624Abstract: A multiple party system for distributing content. In one embodiment, four parties are involved in the system: a consumer, a service provider, an authenticator, and a content provider. The distribution of content from the content provider to the consumer is carried out using a predefined protocol, mutating IDs, watermarks, and licenses. The authenticator controls the distribution of mutating IDs, verifies the identity of one or more participating parties, and provides tracking information for mapping service providers and consumers to particular, possibly watermarked, content items.Type: GrantFiled: May 26, 2004Date of Patent: May 20, 2008Assignee: Imagineer Software, Inc.Inventors: William Cochran, Samuel M. Gustman, William R. Sellars

Patent number: 6966971Abstract: An absorbent printed paper web and methods for making the printed web, the web having a visually discernible larger pattern, which can be a logo, on at least one surface formed essentially only of a paper web and a strengthening, colored bonding material. The printed web having the larger pattern can be made using the same bonding material and process used to print the background pattern. A double recrepe process using an improved Gravure roll may be used to print both logo and background. One method includes using a Gravure roll having deep depressions for printing a geometric background pattern, which can be a cross hatch pattern defining unprinting surface areas between the repeating deep depressions. The Gravure roll can also have shallow depressions in the reverse image of a logo to be printed, where the shallow depressions can have contiguous logo areas much larger than the size of the repeating deep depressions or unprinting surface areas in the background pattern.Type: GrantFiled: April 26, 2002Date of Patent: November 22, 2005Assignee: Sellars Absorbent Materials, Inc.Inventors: John C. Sellars, William R. Sellars, Richard R. Hepford
