Government Owned Inventions Available for Licensing

AGENCY: National Institute of Standards and Technology, Commerce.

ACTION: Notice of Government Owned Inventions Available for Licensing.

-----------------------------------------------------------------------

SUMMARY: The inventions listed below are owned in whole or in part by 
the U.S. Government, as represented by the Department of Commerce. The 
Department of Commerce's ownership interest in the inventions is 
available for licensing in accordance with 35 U.S.C. 207 and 37 CFR 
part 404 to achieve expeditious commercialization of results of 
Federally funded research and development.

FOR FURTHER INFORMATION CONTACT: Technical and licensing information on 
these inventions may be obtained by writing to: National Institute of 
Standards and Technology, Office of Technology Partnerships, Building 
820, Room 213, Gaithersburg, MD 20899; Fax 301-869-2751. Any request 
for information should include the NIST Docket No. and Title for the 
relevant invention as indicated below.

SUPPLEMENTARY INFORMATION: NIST may enter into a Cooperative Research 
and Development Agreement (``CRADA'') with the licensee to perform 
further research on the inventions for purposes of commercialization. 
The inventions available for licensing are:

    NIST Docket Number: 97-047US.
    Title: Implementation of Role/Group Permission Association Using 
Object Access Type.
    Abstract: Security administration in a computer system is 
simplified by defining a new and independent entity called an Object 
Access Type (OAT). OATs comprise access control specifications 
associating roles with

[[Page 43355]]

permissions, and associating the roles with a set of objects, such as 
resources or files. Different roles may have differing permissions to 
objects associated with an OAT, and objects may be assigned to plural 
OATs. A mechanism is also presented whereby system administrators are 
provided with the capability to display and manipulate access 
designations by operating only on the independent OATs.

    NIST Docket Number: 98-010US.
    Title: Planar Geometry Superconducting Coil Having Internal Damping 
Resisters.
    Abstract: The invention is jointly owned by the U.S. Government, as 
represented by the Secretary of Commerce, and the University of 
Colorado. The operation of a planar geometry superconducting coil used 
in conjunction with a ground plane is improved by intracoil damping. 
This damping reduces coil resonances. The improvement consists of an 
intracoil shunt, which damps the resonances of the coil by connecting 
each turn, or loop, of the multiturn/multiloop coil with resistors. One 
example of a planar geometry superconducting coil which is effectively 
damped according to the present invention is the input coil to a 
superconducting quantum interference device (SQUID). The intracoil 
shunt may be added to the SQUID at the same time in the SQUID 
fabrication as the junction shunts.

    NIST Docket Number: 98-072US.
    Title: Method For The Chemical Precipitation Of Metallic Silver 
Powder Via A Two Solution Technique.
    Abstract: A method for the chemical precipitation of metallic 
silver powder employs a two solution technique in which a solution of a 
tin salt and a solution of a silver salt are mixed in the presence of 
an inorganic or organic acid, alumina, an anionic surfactant, and a 
colloid to form a precipitation solution at a temperature and pH 
suitable to effect the chemical precipitation of silver. Almost 80% by 
weight of the precipitated powder agglomerate is less than 25 microns 
in diameter, and the individual powder particles which compose the 
agglomerate range in size from 0.2 to 2.0 microns. In addition to the 
favorable size distribution, silver particles precipitated in the 
presence of a gelatin colloid can be used with a minimal amount of 
sieving so that little work hardening is imparted to the particles. The 
powder can be annealed at a temperature of up to 750 degrees C for two 
hours in air with minimal sintering, and the acid-assisted hand 
consolidated of powder produced according to the present technique is 
capable of producing silver compacts which are nearly 80% dense. 
Advantageously, a hand consolidated silver compact which comprises the 
powder of the present invention equals or exceeds the transverse 
rupture strength, shear strength, creep, toughness, corrosion 
resistance, microleakage, and wear properties of conventional silver 
amalgam.
