Publication number: 20010052019Abstract: A video mail delivery system for generating and transmitting video mail between a sender computer and a receiver computer over a communications network, such as the Internet. A video mail file containing audio and video content is recorded in a standard audio video interleave format and is then reformatted and compressed into an advanced streaming format. A video mail message window on the sender computer display enables the addition of an electronic text message to the video mail. A hyperlink to the compressed video mail file is inserted automatically into the video mail message window. When the video mail message is sent, the compressed video mail file is transmitted to a video store and forward server that stores the video mail file until it is accessed by the destination receiver computer.Type: ApplicationFiled: February 5, 2001Publication date: December 13, 2001Applicant: OVT, Inc.Inventors: Robert J. Walters, Richard E. Bennett

Patent number: 5550175Abstract: A solvent-free hot melt process, for preparing a non-thermosettable, pressure-sensitive adhesive from a tackified non-thermoplastic hydrocarbon elastomer. The process employs a continuous compounding device that has a sequence of alternating conveying and processing zones. The processing zones masticate and mix materials in them. Non-thermoplastic elastomers having high molecular weight may be readily compounded into adhesives in the process.Type: GrantFiled: May 5, 1995Date of Patent: August 27, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Timothy D.

Patent number: 4645711Abstract: The pressure-sensitive adhesive layer of the novel tape, like that of Silver U.S. Pat. No. 3,922,464, comprises a copolymer of alkyl acrylate such as isooctyl acrylate and a small amount of emulsifier monomer. The novel tape differs from that of Silver by incorporating tackifier resin, thus better resisting lifting forces at elevated temperatures while also being cleanly removable.Type: GrantFiled: August 26, 1985Date of Patent: February 24, 1987Assignee: Minnesota Mining and Manufacturing CompanyInventors: Louis E. Winslow, Richard E. Bennett, Thomas S. Overstreet

Patent number: 4454179Abstract: A dry transfer article comprising a carrier film bearing a graphic design in the form of one or more layers of ink and an actinic radiation responsive adhesive overlapping the design, the ink serving as a mask to actinic radiation such that only adhesive in non-ink areas is exposed to radiation creating a differential adhesive tack which allows the article to be positioned on the substrate and the carrier film and exposed adhesive to be selectively removed leaving the graphic design and underlying unexposed adhesive bonded to the substrate.Type: GrantFiled: May 10, 1982Date of Patent: June 12, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventors: Richard E. Bennett, Donald V. Flatt
