Process For Producing Atomized Powdered Metal Or Alloy
US Patent:
4402885, Sep 6, 1983
Filed:
Apr 30, 1982
Appl. No.:
6/373464
Inventors:
Frederick K. Roehrig - Columbus OH
Dennis L. McGarry - Granville OH
Dennis L. McGarry - Granville OH
Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
B01J 202
US Classification:
264 11
Abstract:
A process for producing atomized, powdered metal or alloy is disclosed. Streams of molten metal or alloy are forced through orifices whose openings are so small that the surface tension of the molten metal or alloy would otherwise prevent the flow of molten metal or alloy through the orifice.
Diffusion Barrier For Bores Of Glass Fiber Spinners Providing High Corrosion And Oxidative Resistance At High Temperatures
US Patent:
5914439, Jun 22, 1999
Filed:
May 8, 1997
Appl. No.:
8/852861
Inventors:
Dennis McGarry - Granville OH
Assignee:
Owens Corning Fiberglas Technology, Inc. - Summit IL
International Classification:
C03B 37095
US Classification:
65493
Abstract:
A durable, corrosion-resistant glass fiber spinner is prepared by applying as a barrier layer a uniform layer of an alloy, compatible with the material of the spinner, on the walls of the spinner bores. A layer of platinum group metal is applied over the barrier layer.
Titanium Nitride Diffusion Barrier For Platinum-Coated Fiberglass Spinner Bores
US Patent:
5385595, Jan 31, 1995
Filed:
Dec 23, 1993
Appl. No.:
8/172358
Inventors:
Dennis L. McGarry - Granville OH
Assignee:
Owens-Corning Fiberglas Technology Inc. - Summit IL
International Classification:
C03B 3704
US Classification:
65515
Abstract:
A durable, corrosion-resistant fiberglass spinner is prepared by applying a uniform layer of titanium nitride to the bores of the spinner by chemical vapor deposition, and applying over the layer of titanium nitride a layer of platinum by transient liquid phase deposition.
Cobalt Based Alloys With Critical Carbon Content For Making And Using In Glass Fiber Production
US Patent:
4904290, Feb 27, 1990
Filed:
Sep 30, 1988
Appl. No.:
7/251281
Inventors:
David J. Gaul - Granville OH
Dennis L. McGarry - Granville OH
Dennis L. McGarry - Granville OH
Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
C03B 3704, C03B 37095
US Classification:
65 1
Abstract:
Cobalt based alloys which include chromium, nickel, tungsten, tantalum, zirconium, carbon and boron are provided which are suitable for forming spinners to be used in forming glass fibers. The alloys contain critically important amounts of carbon which maximizes the stress rupture life of the spinner alloy and minimizes the creep rate thereby making the alloy outstandingly adapted for glass manufacture.
Glass Corrosion Resistant Cobalt-Based Alloy Having High Strength
US Patent:
4820324, Apr 11, 1989
Filed:
May 18, 1987
Appl. No.:
7/029824
Inventors:
David J. Gaul - Granville OH
Dennis L. McGarry - Granville OH
Dennis L. McGarry - Granville OH
Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
C03B 3704
US Classification:
65 8
Abstract:
An alloy suitable for use as a spinner in forming glass fibers is provided. The alloy has outstanding stress rupture-life and is highly resistant to the erosion and corrosion of molten glass. The alloy is a cobalt-based alloy and further includes the following in approximate percent by weight, Carbon 0. 5 to 1. 0; Silicon 0. 01 to 0. 15; Chromium 30 to 40; Nickel 5 to 15; Tungsten (Wolfram) 4 to 7; Yttrium 0. 5 to 1. 5; Tantalum 2 to 5; Boron 0. 005 to 0. 04; Zirconium 0. 1 to 0. 4. The alloy typically will include the following as impurities, the amounts indicated being in percent by weight unless otherwise set forth: Aluminum 0 to 0. 2%; Titanium 0 to 0. 2%; Manganese 0 to 0. 01%; Iron 0 to 1%; Phosphorous 0 to 0. 005%; Molybdenum 0 to 0. 10%; Sulfur 0 to 0.
Manufacturing Glass With A Bushing Having A Directionally Aligned Dispersion Strengthened Tip Plate
US Patent:
4274852, Jun 23, 1981
Filed:
Aug 17, 1979
Appl. No.:
6/067590
Inventors:
Dennis L. McGarry - Granville OH
Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
C03B 3702, B22F 320
US Classification:
65 2
Abstract:
An improvement in the manufacture of fibrous glass products is provided by employing a bushing in which the bottom wall, or tip plate, is fabricated of a properly aligned dispersion strengthened precious metal, or alloy thereof.
Interdiffused Chromium/Nickel Corrosion-Resistant Coating For Fiberglass Spinner Bores
US Patent:
5417735, May 23, 1995
Filed:
Dec 23, 1993
Appl. No.:
8/172338
Inventors:
Dennis L. McGarry - Granville OH
International Classification:
C03B 3704
US Classification:
65492
Abstract:
A corrosion-resistant fiberglass spinner is prepared by applying consecutive, alternating layers of chromium and nickel to the bores of the spinner, and thereafter thermally interdiffusing the chromium and nickel to form a corrosion-resistant coating.

Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
B01J 206
US Classification:
264 11
Abstract:
An increase in fine particle metal production is realized when the descending molten metal stream is caused to impinge upon one of two descending fluid streams at a locus offset from the locus of intersection of the two descending fluid streams.
