Filed:

Apr 24, 2003

Appl. No.:

10/422154

Inventors:

Robert A. Horton - Chesterland OH
Claude H. Watts - Hudson OH

Assignee:

Precision Metalsmiths, Inc. - Cleveland OH

International Classification:

B28B 736

US Classification:

106 382, 106 3822, 106 3827, 106 389, 164 15, 164520, 164528, 164529

Abstract:

An improved phosphate-type refractory investment material and method for marking solid investment molds especially useful for casting high melting point metals and alloys, such as platinum and the like. The material consists essentially of one or more phosphate salts, one or more water soluble organic acids, and refractory powder. The material can be prepared as a dry powder blend which is easily shipped to the user and mixed with water at the time of investing the flask. Alternatively, the salt and/or organic acid can be combined with the refractory powder at the time of mixing with water.

Abstract:

An improved phosphate-type refractory investment material and method for making solid investment molds especially useful for casting high melting point metals and alloys, such as platinum and the like. The material consists essentially of one or more phosphate salts, a water soluble acidic constituent, and refractory powder. The material can be prepared as a dry powder blend which is easily shipped to the user and mixed with water at the time of investing the flask. Alternatively, the salt and/or acidic constituent can be combined with the refractory powder at the time of mixing with water.

International Classification:

C08L061/00

US Classification:

525153000

US Patent:

Filed:

Dec 20, 1982

Appl. No.:

6/451300

Inventors:

Robert L. Horton - Chagrin Falls OH
George V. Lakey - Bartlesville OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C22B 6002
C01G 4301

US Classification:

423 20

Abstract:

Mineral values, particularly uranium, are recovered from mineral containing ore by separating the ore into a coarse fraction and a fines fraction, adding a diluent solid material, such as a portion of barren coarse fraction to the fines fraction and leaching the thus diluted fines fraction with a leach solution. The coarse fraction is separately leached, preferably under mild conditions of temperature and leach solution concentration. In another aspect, the total ore is leached, preferably under mild conditions, the thus leached ore is separated into a coarse fraction and a fines fraction, the fines fraction is again leached and at least a part of the leached fines fraction from the second leach step is recycled to the first leach step.

International Classification:

B22C 100

US Classification:

164519

Abstract:

A ceramic shell mold having the properties of being easily removed from the metal castings, high permeability, and a fired strength that can be controlled at levels lower than conventional molds, characterized in that the refractory used to make the mold is at least in part hydrated alumina.

International Classification:

C08L 9100

US Classification:

260 285R

International Classification:

B22C 902

B22C 700

US Classification:

164 34

Abstract:

A pattern set-up especially useful for making prosthetic dental appliances is assembled by attaching a plurality of refractory casts to a support member so that adjacent casts along the length of the support member are circumferentially offset with respect to one another. The casts carry expendable patterns that are connected to the support member by gating systems laid down on faces of the casts. The support member has outward protrusions supporting the weight of the casts and may be formed by a plurality of segments fitted together in end-to-end relation.
