Abstract: A carbon material is formed by heat-treating a carbonaceous material in a reaction mix of oxides of boron and boron nitride in a nitrogen atmosphere to temperatures of 1600 to 2000° C. The surface of the carbonaceous material is transformed into a carbon material that is resistant to oxidation to temperatures of 900° C., enabling machined components to be utilized for weeks at that temperature. The carbon material is also stable in inert or vacuum environments to temperatures in the range of 1500 to 2000° C., enabling its use as aluminum evaporative boats and the like.

Abstract: A modular display system for display devices, especially flat screen monitors which is a hub and spoke design whereby multiple monitors are mounted at the same hub height. The display system has means for locking the height of each display device using a cam and brake concept adjusted using a jackscrew. For quick change-out of display devices, a bayonet mount is used to attach the display device to the spokes.
