Title: Water heater having raw fuel jet pilot and associated burner clogging detection apparatus
Inventor: PEART JACOB A
IPC: F23N5/10
Filed: 2005-03-09
Abstract: A radiant gas burner within the combustion chamber of a water heater has a pilot flame created using a raw fuel jet that impinges on an interior surface portion of a flame holding outer burner wall portion, representatively of a metal wire mesh material, and is mixed within the burner with combustion air delivered thereto from outside the combustion chamber. The resulting fuel/air mixture passes outwardly through the impinged upon mesh wait portion, which functions as a pilot flame stabilizing structure, and is ignited to form a pilot flame on the exterior of the burner body. A thermocouple portion of a clogging detection system senses a change in the pilot flame shape caused by particulate clogging of the metal mesh material and responsively terminates further gas supply to the water heater.

Abstract: [PROBLEMS] To stabilize the survival of transplanted hematopoietic stem cells by using HLA-matched activated lymphocytes. [MEANS FOR SOLVING PROBLEMS] HLA-matched activated lymphocytes in mononuclear cells separated from peripheral blood or umbilical cord blood are proliferated and activated. After separating and collecting, the HLA-matched activated lymphocytes are employed as the main component of a composition for stabilizing the survival of transplanted hematopoietic stem cells. The obtained composition is widely usable in, for example, prevention of insufficient survival of transplanted hematopoietic stem cells and therapy for promoting the survival thereof. Although the dose of the composition varies depending on the age, conditions, etc. of a patient, a humanized antibody is administered in a dose of from 0.2 to 20 mg/kg/day to mammals including humans. The composition is administered by intravenous injection either once a day (single administration or continuous administration) or intermittently 1 to 3 times in a week or once in 2 or 3 weeks.
