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 by the U.S. Government, 
as represented by the Department of Commerce, and are 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: Marcia Salkeld, National Institute of Standards and 
Technology, Office of Technology Commercialization, Physics Building, 
Room B-256, 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: The inventions available for licensing are:

NIST Docket No. 91-001
Title: Improved Oscillating Tube Densimeter
Description: The oscillating tube densimeter provides a unique 
measurement of fluid density. The invention consists of an electrically 
conducting tube, through which the fluid is passed, surrounded by a 
magnet. A current passed through the tube thus generates 
electromagnetic forces. These forces, in turn, generate a resonant 
frequency in the tube which can be accurately determined through a 
measurement of the induced voltage. Since the resonant frequency is 
dependent on the density of the fluid, it can thus be correlated to 
this induced voltage.
NIST Docket No. 92-008
Title: Sensing of Gas Metal Arc Welding Process Characteristics for 
Welding Process Control
Description: A method of monitoring and controlling the gas metal arc 
welding process. The weld electrical signals contain information on the 
welding process characteristics. This invention monitors the welding 
process using a personal computer and develops control responses from 
the information contained in these signals.
NIST Docket No. 92-036
Title: Oxygen-Containing Organic Compounds As Boundary Lubricants for 
Silicon Nitride Ceramics
Description: Several oxygen-containing compounds have been identified 
as having boundary lubricating capability with silicon nitride 
ceramics. Effective lubrication can be obtained over a range of 
molecular weight and concentration, with some compounds suitable at 
concentrations of as little as 1% in a paraffinic oil.
NIST Docket No. 92-038
Title: Optical Technique for Monitoring Electrochemical Interfaces
Description: This invention allows real time measurement of the 
progress of a chemical reaction at an electrochemical interface. This 
is done by utilizing a coherent light source, without removing the 
solid interface from the sample and without stopping the chemical 
reaction. The light sources used in the invention, which can include a 
helium neon laser or a solid state laser, monitor the progress of a 
reaction by detecting changes in reactionary surface roughness and 
polarizability. A wide range of chemical reactions may be measured, 
including, for example, metal finishing, electrochemical machining, 
corrosion protection, metal deposition, electrochemical production, 
waste water treatment, or electrowining.
NIST Docket No. 92-050
Title: Compton Scattering Tomography
Description: New NIST technology generates tomographic images of solid 
objects that can only be examined from a single side. Based on Compton 
scattering of gamma rays of X-rays, the NIST-generated images reveal 
different densities within a material.
NIST Docket No. 92-051
Title: Methods and Electrolytic Compositions for Electrodepositing 
Chromium Coatings
Description: A new NIST process deposits chromium plating up to 600 
microns thick, without using or generating carcinogenic byproducts. The 
plating process uses non-toxic trivalent chromium and the plating is 
three to four times harder, after heating, than depositions using 
hexavalent chromium.
NIST Docket No. 92-052
Title: Contactless Magnetically Coupled Linewidth System
Description: Linewidth measurements are made on integrated circuit test 
structures via magnetic coupling, removing the need for electrical 
contacts. A potential source of contamination is eliminated which 
reduces the possibility of circuit damage during testing.
