US Patent:

40362779, Jul 19, 1977

Filed:

Oct 17, 1975

Appl. No.:

5/623411

Inventors:

Kent Woonton - Kitchner, CA
Jeffrey R. Short - Lincolnshire IL
Kenneth N. Roach - Willowdale, CA

Assignee:

J. R. Short Milling Co. - Chicago IL

International Classification:

B22C 1508

US Classification:

164 16

Abstract:

In the production of foundry mold parts by the method described in U. S. Pat. No. 3,739,834, the production rate is increased by employing a foundry sand mix which can be cured by means of a gaseous curing agent and carrying out curing of the pressed mold part while the mold part is supported at the pressing station.

Filed:

Jun 9, 1997

Appl. No.:

8/871672

Inventors:

Raleigh J. Wilkinson - Lockport IL
Jeffrey R. Short - Lincolnshire IL

Assignee:

J. R. Short Milling Company - Chicago IL

International Classification:

A21D 200

US Classification:

426622

Abstract:

Whole kernel corn is ground and sifted to separate a coarse particle fraction which is then heated with lime and water to a temperature of at least 71. degree. C. and below 100. degree. C. , preferably about 99. degree. C. or less, for up to about 15 minutes. A fine particle fraction from the sifting step can be combined with the heat treated coarse fraction. The resulting heat treated mixture is then dried under a vacuum while continuously mixing for at least about 20 minutes to obtain a dried masa flour having a moisture content of about 7% to about 12% by weight. Thereafter, the dried masa flour can be ground while maintaining the temperature below the gelatinization temperature to reduce the particle size of the masa flour without further gelatinization.

International Classification:

B22C 1502

US Classification:

164161

Abstract:

Apparatus for continuous, high speed production of foundry mould parts by pressing them from a continuous bed of foundry sand mix which is based on a curable binder, pressing of the part being carried out at a time when the mix has adequate plastic flowability for pressure moulding and adequate potential curability to assure a strong, rigid cured product. Advantageous embodiments include curing means operating in conjunction with the pressing means.
