US Patent:

49578219, Sep 18, 1990

Filed:

May 30, 1989

Appl. No.:

7/357836

Inventors:

Richard D. Nicholson - Chardon OH
Sandeep Jain - Mentor OH

Assignee:

AMAX Inc. - New York NY

International Classification:

B32B 1501

US Classification:

428651

Abstract:

Aluminum-molybdenum composite sheet is produced by assembling aluminum and molybdenum sheets to form a billet, rolling the assembled billet in a protective atmosphere at a temperature of about 100. degree. to 400. degree. C. to affect a reduction in thickness of at least about 40% to provide a bonded billet. The billet can be further reduced by hot and/or cold rolling.

Martin Marietta Corporation - Bethesda MD

International Classification:

C04B 735
C04B 7352

US Classification:

106 90

Abstract:

A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and an admixture comprising a mixture selected from an olefin sulfonate, an alkylarylsulfonate, an alkyloamide, an ethoxylated fatty amine, an alkanolamine, and a hydrolyzed starch having a dextrose equivalent value in the range of commercial corn syrups, the admixture being present in an amount sufficient to increase the compressive strength of nonplastic cementitious mixes such as those used in making masonry units, pipe and the like. Generally, the additive is present in an amount between 0. 005 and 0. 5 weight percent based on weight of cement.

Appl. No.:

7/525168

Inventors:

Richard D. Nicholson - Chardon OH
Ronald S. Fusco - Mentor OH

International Classification:

B32B 1502
B23K 2002
B23K 2004

US Classification:

148 115Q

Abstract:

Directed to the production of composite copper-molybdenum sheet by assembling at least one plate of molybdenum with at least one plate of dispersion-strengthened copper to form a composite billet, heating the billet in a protective atmosphere to a temperature within the hot working range for copper, working the billet in a protective atmosphere to effect a reduction in thickness of at least about 40% to bond said dispersion-strengthened copper and said molybdenum together and thereafter further working the resulting bonded billet.

Appl. No.:

6/782682

Inventors:

Richard R. Nicholson - Lyndhurst OH
Arthur H. Gerber - Solon OH

Assignee:

Sandoz Ltd. - Basel

International Classification:

C04B 2418
C04B 2422

US Classification:

524 3

Abstract:

Cement mix, particularly concrete mixes, for high compressive strength including early compressive strength, have extended workability without substantial loss in rate of hardening when containing an admixture combination of a sulfonated naphthalene-formaldehyde condensated and fractionated sulfonated lignin, such as ultrafiltered lignosulfonate.
