    Abstract: A fixturing and sealing mechanism for holding pipes or other workpieces of various sizes and at the same time affording a vacuum seal. Two arcuate or contoured members are pivoted about end walls of a vacuum chamber so that the radii of the two members abut in sealing relation. Each member contains a semicircular surface aperture of decreasing radius. By rotating the two members, circular apertures of different diameters are created by the intersection of the two members, and a seal is provided in the end wall of the chamber to accommodate different size workpieces.

    Abstract: C02 particles, including small particles for laser chamber cooling and large particles for remote mixing purposes, are injected into the stream of an excited energizing gas in a gas laser, the solid C02 subliming to a gas, becoming excited through resonant collision energy transfer with the energizing gas, and emitting photons so as to generate the laser output.
