In making a quick connection and hermetic seal for coupling low pressure systems of a type such as heat pipes and the like, a pre-installed fitting forming the sealing portion of a quick connection assembly is disposed in a depression formed in the sidewall of the low pressure chamber so that the chamber and the sealing portion of the connecting assembly can be fully processed together. The open end of a second system is coupled into the inserted sealing fitting by means of threads formed about a pipe plug device and carried by the tubular end portion of the second system. Sealant applied between the threads of the plug and fitting so that as the plug advances along the fitting a gas-tight seal will be obtained. The fitting includes a sealing membrane disposed across the inserted end thereof to be upset by advancing movement of the tubular end portion carried by the plug.

An arc heater system for producing high purity silicon characterized by the use of an arc heater into which a silicon halide is injected together with a liquid metal reductant, such as an alkali metal, which are reacted together by projecting them into a reaction chamber to cause the formation of liquid silicon, and the walls containing the system being provided with cooling jacket means for preliminarily heating the reactants.

The formation of voids through interdiffusion in bimetallic welded structures exposed to high operating temperatures is inhibited by utilizing an alloy of the parent materials in the junction of the parent materials or by preannealing the junction at an ultrahigh temperature. These methods are also used to reduce the concentration gradient of a hardening agent.

A method of forming a tubular wick for a heat pipe. The method is characterized by the steps of forming a wick blank of a predetermined thickness comprising a plurality of superimposed layers of stainless steel mesh screen, wet rolling the blank for reducing the thickness thereof, wrapping the blank about an inner mandrel, compressing the blank into a rigid tubular structure, removing the tubular structure from the mandrel and sintering the tubular structure.

Disclosed is a method of casting a shape. A laser or electron gun is directed at a fusible powder in a fluidized bed. The beam melts the powder and the melted powder fuses and solidifies on a surface to form the shape. Also disclosed is apparatus for casting a shape. The apparatus includes a fluidized bed containing a fluidized powder, a surface within the bed on which the shape is cast, an electron beam or laser directed at the surface, which has an energy sufficient to fuse the powder, means for controlling the level of the powder in the fluidized bed relative to the surface, and means for controlling the horizontal position of the surface relative to the beam.

The basic heat pipe principle is employed in a heat pipe combination wherein two heat pipes are combined in opposing relationship to form an integral unit; such that the temperature, heat flow, thermal characteristics, and temperature-related parameters of a monitored environment or object exposed to one end of the heat pipe combination can be measured and controlled by controlling the heat flow of the opposite end of the heat pipe combination.
