Title: Hybrid Direct/Indirect Water Heating Process and Apparatus
Inventor: KHINKIS MARK J
IPC: F24H1/10
Filed: 1996-03-08
Abstract: A hybrid direct/indirect liquid heater and a process for heating a liquid in which an unheated liquid is introduced into a direct contact chamber of a hybrid direct/indirect liquid heater where it is directly contacted with hot flue gases exhausted from a cyclonic combustor-heat exchanger.  The unheated liquid in the direct contact chamber condenses any moisture in the hot flue gases, forming contaminated liquid droplets and the contaminated liquid droplets are introduced into an indirect heating chamber of the hybrid direct/indirect liquid heater where they are indirectly heated by contact with the exterior of the combustor-heat exchanger, forming heated contaminated liquid.  Gaseous contaminants are separated from the heated contaminated liquid, forming decontaminated liquid which is accumulated in a hot liquid storage.

Patent CA-2191009-A1 (CA)
Inventor: WATT RONALD
IPC: A01K63/04
Filed: 1996-11-22
Abstract: A protein skimmer for removing impurities in a body of water comprising a first elongated passageway, a second upwardly extending elongated passageway, a fluid path between the passageways to allow fluid travelling in said first passageway to enter the second passageway and a source of air bubbles in fluid communication with the first passageway.   The protein skimmer of the present invention allows for the combination of the co-current and the counter-current skimming actions without the need for additional  air  feeding  means.    This  is  achieved  by displacing a body of water upwardly by the use of the air bubbles, which results in a co-current skimming action, and by providing an area for the body of water to flow downward, which, with the air bubbles' tendency to rise, results in a counter-current skimming action.
