  • Publication number: 20030084896
    Abstract: A compact, highly flexible and efficient, multi-positionable, multi-dimensional and multi-stage gas-fired heat exchanger system as described. The system is connectable in a forced air duct regardless of the angular position and size of the duct. The heat exchanger comprises one or more heat transfer tubes which are shaped and dimensioned as dictated by the customized use of the heat exchanger. The tubes are secured to a support panel as well as the gas burner associated with each of the inlet openings of the tubes. A position orientable gas valve is secured to a gas distribution manifold. A turbulator may be associated with at least some of the tubes to cause turbulence in the hot combustion flow in each of the tubes to modify the efficiency in heat transfer along one or more sections of the tubes by directing hot combustion gas along an inner circumferential wall of the tubes.

  • Publication number: 20030055247
    Abstract: In accordance with the present invention, there is provided a novel class of heterocyclic compounds. Compounds of the invention contain a substituted, unsaturated five, six or seven membered heterocyclic ring that includes at least one nitrogen atom and at least one carbon atom. The ring additionally includes three, four or five atoms independently selected from carbon, nitrogen, sulfur and oxygen atoms. The heterocyclic ring has at least one substituent located at a ring position adjacent to a ring nitrogen atom. This mandatory substituent of the ring includes a moiety (B), linked to the heterocyclic ring via a carbon-carbon double bond, a carbon-carbon triple bond or an azo group. The mandatory substituent is positioned adjacent to the ring nitrogen atom. Invention compounds are capable of a wide variety of uses.

  • Patent number: 6465529
    Abstract: An aqueous low temperature oxidation (ALTO) process wherein a catalyst or catalyst precursor constituted of a solids support, or powder component, and a metal, or metals component, inclusive of cobalt, is oxidized, reduced and rendered catalytically active for conducting carbon monoxide hydrogenation reactions. The cobalt catalyst or cobalt catalyst precursor is thus contacted at low temperature with an oxidant in the presence of water (e.g., water to which an oxidant is added), sufficient to oxidize the cobalt metal, or metals component of the catalyst or catalyst precursor. On reduction, the hydrogenation activity of the cobalt catalyst is increased. All or a portion of the cobalt metal of the catalyst precursor is oxidized to form a Co2+ cationic or oxo-anionic species at least during the initial phase of the reaction.
