US Patent:

59891700, Nov 23, 1999

Filed:

Nov 25, 1997

Appl. No.:

8/978042

Inventors:

Charles M. Hart - Streetsboro OH
James D. Rogers - Mantua OH
Harry L. King - Hudson OH
John J. Bartholomew - Mentor OH

Assignee:

Global Consulting, Inc. - New Castle PA

International Classification:

F27D 2300

US Classification:

492 48

Abstract:

An insulating roller cover is now disclosed that provides a highly desirable combination of features. The cover is free from asbestos and is therefore of more desirable construction for handling and use. For the roller cover, at least substantially ceramic fiber is highly compressed, providing a dense and refractory, elevated temperature resistant insulating cover. The cover may itself serve as a load bearing surface; or may provide a foundation or protective media for annular discs or 10 sleeve members made of various, load bearing materials. These load bearing materials may be unable to resist direct contact with the shaft due to thermal shock or the differences in their respective expansion and contraction rates. Where impregnant is utilized with the highly compressed fiber, such will often comprise a colloidal substituent.

Appl. No.:

6/626451

Inventors:

Harry L. King - Hudson OH

Assignee:

Eltech Systems Corporation - Boca Raton FL

International Classification:

C22C 2912

US Classification:

75233

Abstract:

A cermet is produced by providing a bulk reaction mixture of particulate reactants plus elemental metal, which reaction mixture is in admixture with a ceramic diluent that is the same as ceramic material formed during sintering of the reaction mixture. Sintering produces a boride-oxide ceramic with the oxide being a metal oxide of the elemental metal. However, the elemental metal is present in the reaction mixture in substantial excess over that amount stoichiometrically required. Sintering is conducted under inert atmosphere, generally after pressing. The invention is particularly directed to boride-based ceramics containing aluminum, which materials are suitable as components of electrolytic cells for the production of aluminum by molten salt electrolysis.

Filed:

Inventors:

- Sanibel FL, US

International Classification:

B22F 3/10

C25C 3/08

Abstract:

Compositions suitable for use in an electrolytic cell for producing aluminum are provided. The compositions can contain a powder blend of boron oxide, a titanium dioxide, aluminum, and titanium diboride. The powder blend can be compacted into tiles and arranged as a cathode surface. The boron oxide and the titanium dioxide in the tiles can be made to react under low temperature molten aluminum to produce titanium diboride in situ. The reaction yields a dense dimensionally stable wettable cathode substrate that can reduce the power consumption in the aluminum electrowinning process.
