US Patent:

51887142, Feb 23, 1993

Filed:

Nov 12, 1991

Appl. No.:

7/790952

Inventors:

Jeffrey Davidson - Millburn NJ
Robert Sherman - New Providence NJ

Assignee:

The BOC Group, Inc. - Murray Hill NJ

International Classification:

C25F 324
C21D 174
C23C 1100

US Classification:

20412935

Abstract:

The present invention provides a method for surface passivating stainless steel articles against the effects of corrosive materials having activities anywhere from aqueous salt solutions to corrosive gases such as hydrogen chloride and silane. Additionally, after the treatment and exposure of the article to moisture, when the article is subsequently flushed with a dry gaseous fluid, the time that the article takes to exhibit an acceptable moisture outgassing rate is reduced over an untreated article. In accordance with the present invention, the surface to be passivated is flushed with a dry gaseous fluid, chemically non-reactive with the stainless steel and containing essentially no oxygen. During such flushing, the articles is baked and cooled. The baking is accomplished at a predetermined temperature and time (preferably between about 250. degree. C. and 500. degree. C.

6/108411

Inventors:

Robert F. Sherman - Brooklyn NY

International Classification:

E04G 300

US Classification:

2482891

Abstract:

A mud flap mounting device for use with a tractor trailer truck is disclosed comprising a frame member adapted for attachment to the tractor truck and having an upper surface with a trough therein, a generally L-shaped support rod having a first leg adapted for attachment to a mud flap and a second leg rotatably mounted to the frame member to rotate between a first position wherein the mud flap is adjacent a wheel to a second position 180. degree. therefrom, and biasing means for yieldably maintaining the support rod in the first position and alternatively in the second position.
