Fibrous Refractory Composite Insulation

View page
US Patent:
4148962, Apr 10, 1979
Filed:
Sep 8, 1978
Appl. No.:
5/940688
Inventors:
Robert A. Administrator of the National Aeronautics and Space Frosch
Daniel B. Leiser - San Jose CA
Howard E. Goldstein - Saratoga CA
Marnell Smith - San Jose CA
International Classification:
C04B 3580
C04B 3514
C04B 3518
US Classification:
428366
Abstract:
A refractory composite insulating material prepared from silica fibers and aluminosilicate fibers in a weight ratio ranging from 1:19 to 19:1, and about 0. 5 to 30% boron oxide, based on the total fiber weight. The aluminosilicate fiber and boron oxide requirements may be satisfied by using aluminoborosilicate fibers and, in such instances, additional free boron oxide may be incorporated in the mix up to the 30% limit. Small quanitites of refractory opacifiers, such as silicon carbide, may be also added. The composites just described are characterized by the absence of a nonfibrous matrix.

Spray Coating Apparatus Having A Rotatable Workpiece Holder

View page
US Patent:
4312292, Jan 26, 1982
Filed:
Sep 22, 1978
Appl. No.:
5/945040
Inventors:
Marnell Smith - San Jose CA
Victor W. Katvala - San Jose CA
Ernest E. Porter - Saratoga CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
B05C 1100
B05C 1302
US Classification:
118320
Abstract:
A spray coating apparatus is provided for rotating a workpiece relative to a spray station to obtain a uniform coating of the workpiece. In a typical example, the workpiece comprises a ceramic tile which is to be coated with a ceramic coating and the tile is to be used as a reusable component of the thermal protection system for a space shuttle. The apparatus for rotating the workpiece includes a base support having a first rotatable stage for rotation in the horizontal plane and a second rotatable stage for rotation in a second plane inclined at an angle, such as 45 degrees, to the horizontal plane and the workpiece is supported on this second stage. Thus the workpiece is rotatable in both of two planes of rotation. The workpiece support is detachable from the first rotatable stage and the workpiece is readily detachable from the workpiece support to facilitate off loading of the spray coated workpiece. The workpiece holder includes a spray guard extending around the periphery of the workpiece to shield that surface of the workpiece where no coating is desired.

Silica Reusable Surface Insulation

View page
US Patent:
3952083, Apr 20, 1976
Filed:
Dec 26, 1973
Appl. No.:
5/427775
Inventors:
James C. Administrator of the National Aeronautics and Space Fletcher
Howard E. Goldstein - Saratoga CA
Marnell Smith - San Jose CA
Daniel Leiser - San Jose CA
International Classification:
F27D 704
C04B 3514
US Classification:
264 63
Abstract:
A reusable silica surface insulation (RSI) material is provided by bonding amorphous silica fibers with colloidal silica at an elevated temperature. The surface insulation is ordinarily manufactured in the form of blocks (i. e. , tiles).

Adjustable High Emittance Gap Filler

View page
US Patent:
4308309, Dec 29, 1981
Filed:
May 7, 1980
Appl. No.:
6/147700
Inventors:
Robert A. Administrator of the National Aeronautics and Space Frosch
Daniel B. Leiser - San Jose CA
David A. Stewart - Santa Cruz CA
Marnell Smith - San Jose CA
Carlos A. Estrella - Santa Clara CA
Howard E. Goldstein - Saratoga CA
International Classification:
B32B 2302
F42B 1100
US Classification:
428193
Abstract:
A flexible, adjustable refractory filler (1) is disclosed for filling gaps between ceramic tiles (10, 11) forming the heat shield of a space shuttle vehicle, to protect its aluminum skin (20) during atmospheric re-entry. The easily installed and replaced filler (1) consists essentially of a strip of ceramic cloth (3) coated, at least along both its longitudinal edges (4, 5), with a room temperature vulcanizable silicone rubber compound with a high emittance colored pigment. The filler may have one or more layers (2, 3), as the gap width requires. Preferred materials are basket-weave aluminoborosilicate cloth, and a rubber compounded with silicon tetraboride as the emittance agent and finely divided borosilicate glass containing about 7. 5% B. sub. 2 O. sub. 3 as high temperature binder. The filler cloth strip or tape is cut to proper width and length, inserted into the gap, and fastened with previously applied drops of silicone rubber adhesive.

Toughened Uni-Piece Fibrous Insulation

View page
US Patent:
5079082, Jan 7, 1992
Filed:
Jan 18, 1989
Appl. No.:
7/298149
Inventors:
Daniel B. Leiser - San Jose CA
Marnell Smith - San Jose CA
Rex A. Churchward - Mountain View CA
Victor W. Katvala - San Jose CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
B32B 514
US Classification:
4283077
Abstract:
A porous body of fibrous, low density silica-based insulation material is at least in part impregnated with a reactive boron oxide containing borosilicate glass frit, a silicon tetraboride fluxing agent and a molybdenum silicide emittance agent. The glass frit, fluxing agent and emittance agent are separately milled to reduce their particle size, then mixed together to produce a slurry in ethanol. The slurry is then applied to the insulation material and sintered to produce the porous body.

Ceramic/ceramic Shell Tile Thermal Protection System And Method Thereof

View page
US Patent:
4713275, Dec 15, 1987
Filed:
May 14, 1986
Appl. No.:
6/862925
Inventors:
Salvatore R. Riccitiello - San Jose CA
Marnell Smith - San Jose CA
Howard E. Goldstein - Saratoga CA
Norman B. Zimmerman - Los Gatos CA
Assignee:
The United States of America as represented by the Administrator of the
National Aeronautics and Space Administration - Washington DC
International Classification:
B32B 106
US Classification:
428 76
Abstract:
The present invention discloses a ceramic reusable externally applied thermal protection system (TPS). The system functions by using the composite device created by combining an upper shell, thermal insulation and lower tile components shown in FIG. 2. The upper shell effectively separates its primary functions as a toughened outer-surface and load carrier. In a preferred embodiment, a structurally strong ceramic/ceramic upper shell is manufactured from ceramic cloth upon which additional ceramic material has been deposited and maintains the configuration of the upper shell. The lower tile is composed of lightweight ceramic normally acceptable in this application. One or more lightweight rigid or flexible insulation materials are used in the cavity created by combining the upper shell and lower tile. The assembly of the overall tile is facilitated by attachment means effective to withstand the temperature and stress conditions. These attachment means include a self-locking wedge and complementary surface, ceramic pins, augers and the like.
