Filed:

Sep 15, 1995

Appl. No.:

8/528913

Inventors:

James W. Osborne - San Jose CA
Michael D. McDaniel - Sunnyvale CA

Assignee:

Apple Computer, Inc. - Cupertino CA

International Classification:

G06F 944

US Classification:

395702

Abstract:

A PowerPC based Network Operating System Loadable Module (NOSLM) is concatenated onto an Intel-based NOSLM and offsets are adjusted to account for the size of the Intel-based NOSLM. The resulting enlarged NOSLM appears as a typical Intel-based NOSLM to Intel-based servers. When the enlarged NOSLM is loaded by PowerPC-based servers, the offsets are used to point the server to the beginning of the PowerPC-based NOSLM code and the Intel-based NOSLM is interpreted as a machine-specific header.

Abstract:

An improved waveguide flange is disclosed for high power operation that helps prevent arcs from being initiated at the junctions between waveguide sections. The flanges at the end of the waveguide sections have counterbores surrounding the waveguide tubes. When the sections are bolted together the counterbores form a groove that holds a fully annealed copper gasket. Each counterbore has a beveled step that is specially configured to insure the gasket forms a metal-to-metal vacuum seal without gaps or sharp edges. The resultant inner surface of the waveguide is smooth across the junctions between waveguide sections, and arcing is prevented.
