US Patent:

59115645, Jun 15, 1999

Filed:

Mar 31, 1997

Appl. No.:

8/829776

Inventors:

James K. Sawyer - Houston TX

International Classification:

F04B 3500

US Classification:

417369

Abstract:

The present disclosure is directed to a power plant, and especially two or more such power plants connected together. The power plant especially features a piston connected with a reciprocated but non-rotating piston rod which connects with a pump piston at the opposite end. Power is generated by the power piston and imparted through straight reciprocating motion to the pumped piston. Two or more of these power plants are operated together by connecting them together through a connective link so that operation of one times the operation of two or more units slaved to the first. Synchronized operation is obtained.

Filed:

Feb 22, 1984

Appl. No.:

6/582279

Inventors:

Joseph Davidovits - Saint-Quentin, FR
James L. Sawyer - Friendswood TX

Assignee:

Pyrament Inc. - Houston TX

International Classification:

C04B 1904

US Classification:

106 84

Abstract:

An early high-strength mineral polymer composition is formed of a polysialatesiloxo material obtained by adding a reactant mixture consisting of alumino-silicate oxide (Si. sub. 2 O. sub. 5,Al. sub. 2 O. sub. 2) with the aluminum cation in a four-fold coordination, strong alkalis such as sodium hydroxide and/or potassium hydroxide, water, and a sodium/potassium polysilicate solution; and from 15 to 26 parts, by weight, based upon the reactive mixture of the polysialatesiloxo polymer of ground blast furnace slag. Sufficient hardening for demolding is obtained in about 1 hour with this composition.

Appl. No.:

6/708732

Richard E. Heitzmann - Pearland TX
Mark Fitzgerald - Houston TX
James L. Sawyer - Friendswood TX

Assignee:

Lone Star Industries, Inc. - Greenwich CT

International Classification:

C04B 700

US Classification:

106 85

Abstract:

A dry, mineral binder composition is disclosed having from 6 to 25 parts by weight metakaolin, 3 to 30 parts by weight dry potassium hydroxide, 0 to 18 parts by weight slag, 0 to 60 parts by weight of a material selected from the class consisting of fly ash, calcined shale, and calcined clay, and from 1 to 150 parts, by weight, of a finely divided silica, preferably an amorphous silica. The binder is particularly useful in combination with Portland cement for forming concrete compositions.

Appl. No.:

7/533361

James L. Sawyer - Friendswood TX

Assignee:

Lone Star Industries, Inc. - Stamford CT

International Classification:

C04B 728

US Classification:

106708

Abstract:

A hydraulic cement is formed from a Class C fly ash, an alkali metal activator, and citric acid. Mortar and concrete compositions can be prepared with this hydraulic cement. The cement is particularly useful in producing mortar and concrete compositions that achieve high strengths in a short time, in particular, a mortar having a strength of at least 2500 psi in 24 hours, when cured at room temperature.

US Patent:

Filed:

Jan 30, 1978

Appl. No.:

5/873308

Inventors:

James L. Sawyer - Friendswood TX

Assignee:

Lone Star Industries - Houston TX

International Classification:

C04B 702

US Classification:

106 89

Abstract:

A cement with rapid strength gain having normal setting and volume change characteristics and its method of manufacture are disclosed. The cement has substantially all particles over 20 microns removed which advantageously results in higher early strength than normal portland cements. This is important in the prestress and precast concrete industry, and early high-strength cement is desirable for other uses such as patching or resurfacing highways and airport runways or in operations where early form removal is desired. The use of chlorides or other accelerators is unnecessary to obtain early high strengths; although, these and plasticizers can be used if desired.

Inventors:

Richard F. Heitzmann - Pearland TX
Mark Fitzgerald - Houston TX
James L. Sawyer - Friendswood TX

Assignee:

Lone Star Industries, Inc. - Greenwich CT

International Classification:

C04B 700

US Classification:

106 85

Abstract:

A binder composition for Portland cement is disclosed, said composition including 100 parts by weight metakaolin and, based upon said metakaolin, from 20 to 70 parts by weight slag; from 85 to 130 parts by weight of at least 1 material selected from the class consisting of fly ash, calcined shale, and calcined clay; from 70 to 215 parts by weight finely divided silica, preferably amorphous silica; and from 55 to 145 parts by weight of a mixture of potassium silicate and potassium hydroxide, wherein at least 55 parts by weight is potassium silicate. The binder composition can be mixed with Portland cement or with a combination of Portland cement and fly ash to provide a composition curable to a material having a high early strength and a high ultimate strength.

Appl. No.:

7/103755

Inventors:

Richard F. Heitzmann - Pearland TX
Billy B. Gravitt - Katy TX
James L. Sawyer - Friendswood TX

Assignee:

Pyrament, Inc. - Houston TX

International Classification:

C04B 2210

US Classification:

106 89

Abstract:

A blended hydraulic cement composition, curable at low temperatures, including temperatures below the freezing point of water, is composed of portland cement, slag, pozzolans including metakaolin, and admixtures including potassium carbonate and water reducing compositions. The cement is particularly useful in producing concrete compositions which achieve high strength in a brief period of time, and continue curing at ambient temperatures, and temperatures below the freezing point of water.
