DEPARTMENT OF DEFENSE
 

Availability of Exclusive, Partially Exclusive or Non-Exclusive 
Licensing of U.S. Patent Concerning Explosive Stemming Device

AGENCY: U.S. Army Engineer Waterways Experiment Station, DOD.

ACTION: Notice of availability.

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

SUMMARY: In accordance with 37 CFR 404.7(a)(1)(i), announcement is made 
of the availability of U.S. Patent Number 5,092,245 awarded March 3, 
1992 for licensing. This patent will be assigned to the United States 
of America as represented by the Secretary of the Army, Washington, DC.

ADDRESSES: U.S. Army Corps of Engineers, Waterways Experiment Station, 
ATTN: CEWES-CT-C, Vicksburg, MS 39180-6199.

FOR FURTHER INFORMATION CONTACT:
Ms. Norma E. Logue, (601) 634-3076.

DATES: Proposals will be accepted until July 5, 1994.

SUPPLEMENTARY INFORMATION: This patent concerns a device for stemming 
explosives in a borehole to obtain improved coupling of the energy of 
the explosives into the soil or rock adjacent to the borehole. The 
device includes a cylindrical member having a flexible sleeve-like 
liner that conforms to the interior of the cylinder. One end of the 
liner is turned around an end of the cylindrical member so that the 
inner flexible sleeve will evert and empty, thus dropping the granular 
material that is prepackaged in the tube around the detonating line and 
on top of the explosive charge. The stemming device can be lifted to 
the surface or can remain in the shothole.
    The system has potential use in placing explosive or priming 
charges for subsurface seismic investigation or quarrying. The device 
is considered to be useful in that it improves coupling and can be pre-
packaged with selected stemming materials. The unit should reduce the 
probability of having the stemming material bridge the borehole and 
produce a cavity above the explosive charge.
    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, U.S. 
Code, the Department of the Army as represented by the U.S. Army 
Engineer Waterways Experiment Station wishes to license the above-
mentioned technology in an exclusive, partially exclusive or non-
exclusive manner to any parties interested in manufacturing and selling 
devices covered by the above-mentioned patent.
    Each interested party is requested to submit a proposal for an 
exclusive, partially exclusive or non-exclusive license. The proposals 
for manufacturing and selling the device covered by the above-mentioned 
patent will be evaluated using the following criteria: demonstrated 
knowledge and capability to manufacture materials used in blasting 
operations, evaluation of the applicant's plan to construct the 
explosive stemming device employing the patent technology, time 
required to bring device to market and production rate, royalty 
offered, technical capability of applicant's staff in mechanical and 
explosives engineering as judged by resumes of full time staff, and 
small business.
    Proposals will be accepted for a period of 90 calendar days from 
the date of notice in the Federal Register.
Kenneth L. Denton,
Army Federal Register Liaison Officer.
