Patent number: 6145764Abstract: A nozzle assembly includes a readily replaceable nozzle tip which is replaced within a firnace adjacent an installed furnace-side end of a supply nozzle. The nozzle tip is provided with a pair of opposed, spring-loaded pivot pins which snap into apertures in the wall of a stationary nozzle conduit to removably secure the tip to the conduit. The pivot pin connection permits tilting of the tip relative to the stationary conduit in a vertical plane about a horizontal axis extending through both pivot pins. A link arm used for tilting the nozzle tip has a hook-shaped end which connects to a pin extending from the nozzle tip. The hook-shaped end of the link arm permits removal of the nozzle tip without having to remove the link arm from a lever assembly.Type: GrantFiled: October 29, 1999Date of Patent: November 14, 2000Assignee: RV Industries, Inc.Inventors: Daniel Gonzalez, James W.

Patent number: 5407646Abstract: Hydrogen sulfide or other gaseous component is removed from a gas stream containing the same by distribution of the gas stream in the form of fine bubbles by a rotary impeller and stationary shroud arrangement at a submerged location in an aqueous iron or other transition metal chelate solution, or other suitable catalyst, contained in an enclosed reaction vessel. Sulfur particles, or other insoluble phase product, of narrow particle size range formed in the reaction are floated off from the iron chelate solution. An oxygen-containing gas stream also is distributed in the form of fine bubbles by a separate rotary impeller and stationary shroud arrangement at a separate submerged location in the iron chelate solution. The second submerged location generally is separated from the first by a baffle extending downwardly in the reaction vessel from a top closure towards a bottom closure.Type: GrantFiled: April 19, 1993Date of Patent: April 18, 1995Assignee: The University of Toronto Innovations FoundationInventors: James W.
