one former member of the Committee

submitted objections to the NLGA and

wood-treaters memberships. On October

29, 1997, after considering the

Committee’s recommendation and the

comments of those who responded to

the Federal Register notice, the

Secretary of Commerce approved the

recommendation of the Committee to

allow one principal member and one

alternate to represent the NLGA under

Section 9.3.1 of PS 20–94 and one

principal member and one alternate to

represent wood treaters under Section

9.3.3.

Notice of Government Owned

Inventions Available for Licensing

AGENCY: National Institute of Standards

and Technology, Commerce.

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 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: National Institute of

Standards and Technology, Industrial

Partnerships Program, 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

NIST Docket Number: 97–026.

Title: Method and Apparatus for

Diffraction Measurement Using A

Scanning X-Ray Source.

Abstract: This invention is jointly

owned by the U.S. Government, as

represented by the Secretary of

Commerce, and Digiray Corporation.

The present invention relates to x-ray

diffraction measurement by using

moving x-ray source x-ray diffraction.

The invention comprises a rasterscanned x-ray source, a specimen, a

collimator, and a detector. The x-ray

source is electronically scanned which

allows a complete image of the x-ray

diffraction characteristics of the

specimen to be produced. The specimen

is placed remote from the x-ray source

and the detector. The collimator is

located directly in front of the detector.

The x-rays are diffracted by the

specimen at certain angles, which cause

them to travel through the collimator

and to the detector. The detector may be

placed in any radial location relative to

the specimen in order to take the

necessary measurements. The detector

can detect the intensity and/or the

wavelength of the diffracted x-ray. All

information needed to solve the Bragg

equation as well as the Laue equations

is available. The x-ray source may be

scanned electronically or mechanically.

The present invention is used to

perform texture analysis and phase

identification.

NIST Docket Number: 96–042.

Title: High Strength Polymeric

Networks Derived (Meth) Acrylate

Resins With Organoflourine Content

and Process For Preparing Same.

Abstract: Disclosed are fluorinated

materials for use in dental uses and nondental uses, e.g., adhesives or coatings.

Multifunctional monomers and

prepolymers with pendant (meth)

acrylate groups were prepared from

epoxide-ring-opening reactions. Resins

based on the fluorinated monomers and

prepolymers with diluent comonomers,

were photocured as composites with

particulate fillers. Fluorine contents of

the prepolymers ranged from 15 to 65%.

Composites with high transverse

strength (up to 120 MPa), low water

sorption (as low as 0.11 mass %) and

extremely low polymerization shrinkage

(as low as 3.4% by volume) were

obtained. The fluorinated resins may be

employed to produce hydrophobic

dental composite materials with high

strength and low polymerization

shrinkage.

NIST Docket Number: 96–038US.

Title: Fractional Phase Measurement

By Polarization-Dependent

Spectroscopy.

Abstract: The invention provides an

inexpensive, noninvasive optical

method of quantitatively determining

the volume fraction of anisotroic

material in a mixture of anisotropic and

isotropic material, and more particularly

for determining the volume fraction of

noncubic crystalline material in a

mixed-phase specimen having noncubic

crystalline material intermixed with

cubic crystalline material. Polarized

light is impinged on the specimen and

the reflectance or transmission

difference between two orthogonal

polarizations directions is measured. In

cubic regions the reflectance or

transmission is the same along both

polarization directions so the

contributions to the difference cancel,

leaving a signal only from the noncubic

regions. The optical difference can be

measured as a function of wavelength

and critical points in the band structure,

including the band gap, can be profiled.

From the band structure the film

composition can be determined. This

measurement is particularly suited to

measuring III–V nitride semiconductor

specimens having regions with

zincblende symmetry mixed with

regions of wurtzite symmetry.

NIST Docket Number: 96–025

Title: Broadband, UltrahighSensitivity Chemical Sensor Based on

Intra-Cavity Total Reflection.

Abstract: This NIST invention permits

broadband, ultra-sensitive measurement

of optical absorption for any state of

matter by the cavity ring-down

technique using a small, monolithic,

total internal reflection ring cavity. It

significantly advances the sensitivity,

accuracy, and adaptability of optical

absorption spectroscopy for decisive

qualitative and quantitative chemical

analysis, with greatly increased trace

analysis capability.

NIST Docket Number: 95–022.

Title: A Time Stamp Service for the

National Information Network.

Abstract: This NIST invention

consists of a method for applying a

signed time-stamp to a document in

digital format for the purpose of proving

that the document existed on the date it

was signed. Any digital-format

document can be signed including

simple text files, binary files, scanned

images, etc. The document can be

encrypted or encoded. The time-stamp

is accurate to a few milliseconds, and

the accuracy is directly traceable to

UTC(NIST) in real-time. The signed

document can be returned to the sender

electronically and the document can

also be forwarded automatically to any

number of third parties provided only

that the third parties are capable of

receiving electronic mail.
