ANNUAL BELLOWS SEAL Sandia National Laboratories has an intellectual property position on ``Annual Bellows Seal'' (SD-#5691). Through work on DOE-related programs and industry interactions, Sandia is aware that frequently there is a need to seal an annular space (annulus between two concentric tubular, space between cylinder and shaft, etc.) a with a seal that can be engaged and disengaged. We have developed such a technology and are interested in finding potential licensee for its commercialization. Sandia is a government-owned, contractor-operated facility with locations in New Mexico and California. As a research and development laboratory for the Department of Energy (DOE), we have been working on high technology solutions to problems of national importance for over 40 years. Until only recently, the technologies that we developed were kept under lock and key. However, we are now able to negotiate and grant commercial licenses to our intellectual property. Field(s) of use, degree of exclusivity, performance requirements, up front fees and running royalties are all subject to the negotiation process. Sandia's ``Annual Bellows Seal'' overcomes some of the common problems with current annular seals. The most common annular seals operate using Poisson's effect - that produce a seal by squeezing the seal in an axial direction causing the seal to expand in a radial direction. The design of the Annular Bellows Seal is such that higher differential pressures across the seal cause greater sealing capability. Sandia's Annular Bellows Seal element is able to engage and disengage with minimum of force. Potential applications for this technology and the specific technical advantages it possess include: use in tubing or casing plungers, and packers used to seal the annulus between the tubing and casing of a well. In order to satisfy fairness of opportunity requirements, Sandia will widely advertise both the technology and the fact that it may be licensed. Depending upon any prior commitments, the advertised license can take a variety of forms, up to and including the opportunity to negotiate for exclusive rights to the technology. Through a variety of possible marketing venues including: advertisements in the Commerce Business Daily, trade publications, Internet homepages; targeted mail campaigns; and trade show attendance; we accomplish the broad announcement of licensing opportunities. Visit our World Wide Web site at (http://www.sandia.gov/ttrans/ttrans.html). This is not an offer for the sale of a license, but a solicitation of interested parties for potential commercial license opportunities. You and other potential licensees, must express interest in the technology either by writing or faxing us. Sandia will accept commercial license inquiries for this technology until August 30, 1996. In your inquiry, please include any information on your companies' experience and capabilities with similar technologies. Write to: Joanne Trujillo, Sandia National Laboratories, Technology Partnerships Dept., PO Box 5800 - MS 1380, Albuquerque, NM 87185-1380 or express interest by fax at (505) 843-4175. Sandia will evaluate and integrate all respondents; commercial interest in the technology with Sandia's licensing strategy for mutually beneficial agreements. Preference will be given to US based businesses. We look forward to the opportunity to work with you and your company on the desired goal of commercialization of the Annual Bellow Seal technology.
