US Patent:

43465560, Aug 31, 1982

Filed:

May 12, 1980

Appl. No.:

6/148904

Inventors:

Hal H. Rice - Birmingham MI
Gary A. Kruger - Troy MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01N 714
F01N 716
F01N 718

US Classification:

60272

Abstract:

An insulating liner for use in an exhaust port of an internal combustion engine or the like consisting, in a preferred embodiment, of a formed thin wall tubular body of rigidized fibrous ceramic such as fibrous alumina-silica material (Fiberfrax) with an abrasion resistant ceramic coating fused onto the inner gas-exposed surface of the body. The coating comprises a mixture of fused silica cement and fine glass frit sintered in place on the body inner surface at a temperature below that which would damage the thin walls of the body.

Appl. No.:

6/926157

Inventors:

Hal H. Rice - Birmingham MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B22C 108

US Classification:

164529

Abstract:

A foundry mold for casting to size a material-forming die of a zinc-base alloy is formed by compacting and sintering a particulate mixture composed predominantly of alumina particles and containing raw kyanite particles. During sintering, the raw kyanite particles react to expand the mold by an amount sufficient to compensate for shrinkage of the solidified alloy during cool down.

Filed:

Sep 5, 1978

Appl. No.:

5/939457

Inventors:

Harry R. Mitchell - Bloomfield Hills MI
Hal H. Rice - Birmingham MI

Assignee:

General Motors Corporation - Detroil MI

International Classification:

F02B 7508

US Classification:

123669

Abstract:

Internal combustion engine pistons are provided with aluminum bodies with highly insulative ceramic inserts cast in place in the upper combustion chamber defining wall. In each of the disclosed embodiments, the ceramic insert has tapered edges to dovetail the insert in place. A fibrous ceramic cushioning layer applied around the insert edge before casting distributes cooling stresses and allows limited relative expansion and contraction of the aluminum body and ceramic insert without overstressing either of the members. Other features are also included.

Filed:

Jul 2, 1987

Appl. No.:

7/070146

Inventors:

Hal H. Rice - Birmingham MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

C21C 544

US Classification:

266281

Abstract:

A foundry furnace lining is formed using an improved ramming mix composed predominantly of raw kyanite particles and alumina particles. The particulate mix is sintered to form a silica slag-resistant lining, which sintering is accompanied by reactions that produce compressive forces that strengthen the product lining.

US Patent:

Filed:

Sep 15, 1975

Appl. No.:

5/613474

Inventors:

Harry R. Mitchell - Bloomfield Hills MI
Hal H. Rice - Birmingham MI
James R. Abel - Birmingham MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01N 310

US Classification:

60282

Abstract:

An exhaust reactor manifold having a reaction chamber formed by a hardened insulative ceramic liner which is supported within a protective housing. The liner walls are protected and insulated by compessible fibrous insulation. Springs and wedges in the housing act through the insulation blanket to load the liner walls in compression. Inlet and exhaust ports are provided through angled sealing surfaces of the liner which are urged by the compressive loading of the liner into engagement with mating surfaces of a ported mounting portion of the housing.

Appl. No.:

5/729000

Inventors:

Hal H. Rice - Birmingham MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

C04B 3514

US Classification:

106 69

Abstract:

A method for forming contoured refractory bodies characterized by a low coefficient of expansion, high flexural strength and resistance to thermal shock, wherein a fused silica material is pressed into the desired shape in a porous die at a pressure not greater than about 1500 psi, the batch composition consisting essentially of from about 70-85 parts by weight fused silica of -325 mesh, from about 15-30 parts by weight clay, together with from about 20-28 parts by weight de-ionized water and from about 0. 1-0. 6 parts by weight of at least one of the organic plasticizers selected from the group consisting of hydroxyethyl cellulose, hydroxypropyl cellulose, ethylene oxide resin and propylene glycol alginate, the composition containing less than 0. 3% by weight on an after-fired basis of alkali and alkaline earth metal oxides, the green body being dried and then fired at about 1123. degree. C. for about 6 hours.
