  • Generation of fluorine via thermal plasma decomposition of metal fluoride
    Patent number: 5207999
    Abstract: A compound MF.sub.n, where M is a metal and n is the valency of the metal and has a value between 1 and 6, is subjected to a thermal plasma at a temperature in excess of 3000 K to dissociate it into the metal and fluorine. Also present in the reactor is an added reactant that will react with the metal or the fluorine to prevent their recombination so that there is formed fluorine gas or a fluoride other than the fluoride of the metal M.

  • 3-D Chopped-fiber composites
    Patent number: 4370390
    Abstract: A low-cost composite structure, having near isotropic mechanical properties, produced by molding a matrix material with a reinforcing fiber element. The reinforcing fiber elements are comprised of three or more fibers to form a three-dimensional figure. In the preferred embodiment at least one fiber is oriented in each of the mutually perpendicular planes similar in appearance to a child's jack. The matrix material may be any material which provides a suitable bond with the reinforcing fiber elements.
