Filed:

Mar 5, 2001

Appl. No.:

09/797886

Inventors:

Ronald D. Drake - Lake Arrowhead CA
Michael Helmut Kobler - San Francisco CA
John David Watson - Evergreen CO

Assignee:

Oil Sands Underground Mining, Inc. - Evergreen CO

International Classification:

E21B 4124

US Classification:

299 8, 299 19, 299 18, 299 56, 299 13, 405146

Abstract:

The present invention is directed, inter alia, to devices and methods for excavating valuable materials, particularly soft ores such as oil sands, oil shales, and the like, that use one or more of a number of features, including backfilling for ground support, a small trailing access tunnel, processing of the valuable material in the excavation with the tailings optionally being used as backfill and the valuable material being transported to the surface, a plurality of movable shields for ground support, and/or a movable tail shield to provide interim support to the backfill while additional liner sections are installed and/or formed.

US Patent:

53005694, Apr 5, 1994

Filed:

Feb 10, 1993

Appl. No.:

8/016487

Inventors:

Ronald E. Drake - Grand Junction CO
John M. Labriola - Grand Junction CO

Assignee:

Ricon Resins, Inc. - Grand Junction CO

International Classification:

C08L 3302

US Classification:

525 78

Abstract:

Uncured adhesive elastomeric compositions are provided comprising an unsaturated polymeric dicarboxylic acid or derivative adduct and an elastomer. These compositions are capable of adhesion to a broad, general range of materials and are useful for bonding elastomers to other elastomers, to plastic materials, to metal, fabrics, fibers, paper and miscellaneous substrates. These materials can also be bonded to each other using a film or spreadable liquid comprised of a composition of this invention and curing said film or liquid in contact with said substrates.

Appl. No.:

8/409469

Inventors:

Ronald E. Drake - Grand Junction CO
John M. Labriola - Grand Junction CO

Assignee:

Ricon Resins, Inc. - Grand Junction CO

International Classification:

C08L 2704

US Classification:

525 75

Abstract:

A flowable uncured adhesive elastomeric composition suitable for delivery to assembly sites by pumping through supply lines is provided, which has a tensile strength suitable for formation of a strong bond, comprising: (a) an elastomer having a viscosity higher than flowable; (b) a synthetic resin curable by the same cure system as said non-flowable elastomer in an amount sufficient to lower the viscosity of the mixture to a pumpable level; (c) an unsaturated polymeric adduct of a dicarboxylic acid or dicarboxylic acid derivative in an amount sufficient to provide adhesive properties to the mixture; and (d) a curing agent. Preferably the composition also comprises a crosslink-enhancing coagent in an amount sufficient to lower percent elongation and increase adhesive bond strength of the cured elastomer. The compositions are useful for bonding substrates such as other elastomers, metals, plastics, glass, fibers, paper and fabrics.
