DEVELOPMENTS AT NIST Researchers at the National Institute of Standards and Technology (NIST) have developed a number of new devices and methods involving a variety of technologies. In certain cases other parties have participated in the development of these technologies .NIST may enter into a Cooperative Research and Development Agreement (CRADA) with interested parties to perform further research on the invention for purposes of commercialization. NIST may grant CRADA Partners an option to negotiate for exclusive licenses to any jointly owned inventions which arise from the CRADA as well as an option to negotiate for exclusive royalty-bearing licenses for NIST employee inventions which arise from the CRADA. Anyone interested in the further development of any of these technologies or in applying for a license to commercialize these technologies should send a written request for further information, referencing the NIST Docket Number and Title, to: National Institute of Standards and Technology, Industrial Partnerships Program, Building 820, Room 213, Gaithersburg, Maryland 20899; Telecopy: 301-869-2751. This is not an announcement of a contract action or a grant. NIST DOCKET NUMBER: 95-007PA, Title: Development of High Temperature Ultrasonic Transducers for the In-Situ Measurement of Deformation of Materials During Hot Isostatic Processing, Description: This aluminum nitride film ultrasonic transducer measures deformation of materials in a high-temperature, high-pressure environment such as a hot isostatic pressing (HIP) vessel. It can emit and receive ultrasound at temperatures above 940 degrees celsius and at pressures above 155 Mpa. NIST DOCKET NUMBER: 95-044PA, Title: Sensing and Gas Metal Arc Welding Process Characteristics for Welding Process Control, This method for sensing the characteristics of constant-voltage gas metal arc welding Description: (CV-GMAW) allows control of the welding process so that fluctuations adversely affecting weld quality can be corrected. The algorithms of this invention extend the sensing and process control mechanisms already developed for pulsed-current gas metal arc welding (PC-GMAW), US Patent No. 5,221,825. NIST DOCKET NUMBER: 95-047, Title: Non-Contact Method and Apparatus for Inspection of Inertia Welds, Description: An electromagnetic acoustic transducer (EMAT) provides a means of non-contact inspection to detect internal inertia weld defects and web defects in spool-shaped aluminum airbag inflator igniter canisters. The method is non-destructive, efficient, reliable, and readily implemented. NIST DOCKET NUMBER: 95-050, Title: Fabrication of Embossed Diffractive Optics with Reusable Release Agent Description: By this technique of chemically modifying the surface of a commercial master diffractive grating with a suitable release agent, replica gratings are inexpensively embossed onto float glass, ion diffused, polymer, semiconductor, and other types of optical waveguides. NIST DOCKET NUMBER: 96-029, Title: Cryogenic Current Comparator Based on Liquid Nitrogen Temperature Superconductors, Description: Electric currents maintained in a precise integer ratio by a cryogenic current comparator (CCC) can be used to measure WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm.
