Availability for Exclusive, Partially Exclusive or Nonexclusive
Licensing of U.S. Patents Concerning the Control of the Hardening of
Cements and Binders
AGENCY: U.S. Army Engineer Waterways Experiment Station, DOD.
ACTION: Notice of availability for licensing.
-----------------------------------------------------------------------
SUMMARY: In accordance with 37 CFR 404.7(a)(1)(i), announcement is made
of the availability of U.S. Patents 5,252,266 and 5,268,032 for
licensing. These patents have been assigned to the United States of
America as represented by the Secretary of the Army, Washington, DC.
ADDRESSES: United States Army Corps of Engineers, Waterways Experiment
Station, Attn: CEWES-CT-C, Vicksburg, MS 39180-6199.
FOR FURTHER INFORMATION CONTACT:
Ms. Ruth C. Little, (601)-634-2420.
SUPPLEMENTARY INFORMATION: The patents cover techniques for controlling
the hardening or setting reactions of binders or cements of the type
which require specific alkaline or acidic condition to initiate the
reactions. The techniques described involve mixing an alkali- or acid-
reactive cement with an electrolyte to form a paste. An electric
current is passed through the paste to decompose the electrolyte and
generate an activating agent. The techniques described allow the paste
to be handled and placed prior to the beginning of the setting reaction
thereby avoiding the problems caused by short setting times that can
result in serious flaws in the finished product and/or damaging or
clogging of the mixing equipment. Further, because the activating agent
is first generated at the electrode surface, the techniques are useful
in casting hollow products from the cements and binders mentioned
because there is no need to rotate the mold. The mold can be fabricated
with one electrode in the center and the second electrode forming the
outside of the mold. The acid or alkaline activator can be generated on
the outside edge of the paste. The paste in the center of the mold
remains soft and can be removed. Using this technique there is no need
to rotate the mold to hold the paste out against the mold. The approach
described can be used with starting materials such as ground granulated
blast-furnace slag and a sodium chloride solution.
Under the authority of section 11(a)(2) of the Federal Technology
Transfer Act of 1986 (Pub. L. 99-502) and section 207 of Title 35,
United States Code, the Department of the Army, Corps of Engineers,
Waterways Experiment Station wishes to license the above United States
Patents in an exclusive, partially exclusive or nonexclusive manner to
any party interested in using the technology described in the above
mentioned patents.
Each interested party is requested to submit a proposal for an
exclusive, partially exclusive or nonexclusive license. The proposals
for using this technology will be evaluated using the following
criteria: royalty, technical capability, size of business, and
development plan.

Army Federal Register Liaison Officer.
