Appl. No.:

10/061995

Inventors:

Theodore E. Tedijanto - Cupertino CA, US
Paul Curtis - Atlanta GA, US

Assignee:

Ciena Corporation - Linthicum MD

International Classification:

H04L 12/28

US Classification:

370255, 370236, 370400

Abstract:

A method and system for aggregating a plurality of parallel communications links transmitting data between adjacent nodes in a network is provided. The method simplifies network topology by replacing multiple parallel communications links between nodes in the network with a single aggregated link. The method advertises the available bandwidth of each aggregated link to the network, the available bandwidth being the maximum bandwidth available for any one of the parallel links in the aggregate. The method permits each aggregated link to select which of the parallel links in the aggregate is to be used to transfer data from one node to the other. Aggregating links can be automatic and based on one or more predetermined criteria, such as the service class supported by the parallel links.

Appl. No.:

7/420488

Inventors:

Oscar H. Krikorian - Danville CA
Paul G. Curtis - Tracy CA

Assignee:

United States Department of Energy - Washington DC

International Classification:

F27B 1410
C21B 700

US Classification:

428 358

Abstract:

An improved molten metal containment vessel is disclosed in which wetting of the vessel's inner wall surfaces by molten metal is inhibited by coating at least the inner surfaces of the containment vessel with one or more rare earth oxysulfide or rare earth sulfide compounds to inhibit wetting and or adherence by the molten metal to the surfaces of the containment vessel.

International Classification:

C23C 2002

US Classification:

148248

Abstract:

A process is disclosed for forming a protective metal coating on a metal surface using a flux consisting of an alkali metal fluoride, an alkaline earth metal fluoride, an alkali metal fluoaluminate, an alkali metal fluosilicate, and mixtures thereof. The flux, in particulate form, is mixed with particles of a metal coating material which may comprise aluminum, chromium, mixtures thereof, and alloys containing at least 50 wt. % aluminum and the particulate mixture is applied to the metal surface in a single step, followed by heating the coated metal surface to a temperature sufficient to cause the metal coating material to react with the metal surface to form a protective reaction product in the form of a metal coating bonded to the metal surface. The metal surface which reacts with the metal coating material to form the protective coating may comprise Fe, Co, Ni, Ti, V, Cr, Mn, Zr, Nb, Mo, Tc, Hf, Ta, W, Re and alloys thereof.

International Classification:

G21F 934

US Classification:

588 10

Abstract:

Disclosed is a process for making a ceramic composition for the immobilization of actinides, particularly uranium and plutonium. The ceramic is a titanate material comprising pyrochlore, brannerite and rutile. The process comprises oxidizing the actinides, milling the oxides to a powder, blending them with ceramic precursors, cold pressing the blend and sintering the pressed material.
