  • Molecular beam generator using thermal decomposition for manufacturing semiconductors by epitaxy
    Patent number: 4699083
    Abstract: Arsine or phosphine are thermally decomposed to form a molecular beam of arsenic or phosphorous by using the inside surfaces of a thermal decomposition duct (11) made of quartz or of boron nitride and heated on the outside by radiation from a filament (30). Pierced internal partitions (6a, 6b, 6c, 6d) having successive circumferentially offset holes (6p, 6q, 6r, 6s) increase the decomposition surface area and prevent a molecule from passing through the duct along a straight line.

    Assignee: Compagnie Generale d'Electricite
    Inventors: Daniel Huet, Marc Lambert
  • Process for the manufacture of solutions of halogens
    Patent number: 3975284
    Abstract: Installation for the production of chlorine or chlorine dioxide water or of solutions of a mixture of halogen and halogen derivatives, characterized by a closed circuit under pressure in which circulates water to be enriched, with an over-pressure produced by a pump, the basic chemical element being permanently injected into this circuit by means of a water-ejector, the discharge of the terminal solution, which leaves the reactor under pressure, being compensated by a supply of water to the closed circuit.Application to the treatment of water for drinking, for industrial use and for swimming pools.
