The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors (preferably thermistors) and the shape and alignment of the probe enables accurate readings by reducing the occurrence of condensation on the sensors.Type: GrantFiled: June 1, 2000Date of Patent: February 24, 2004Assignee: Fisher & Paykel LimitedInventors: Lewis George-Gradon, Stephen William McPhee, Paul John Seakins, Peter John Leonard

Publication number: 20040004299Abstract: A humidifier including a steam generator with a container for water and an immersed heating module. The heating module has a spherical shape and is formed of a stainless steel outer surface and an aluminum inner body. Electrical heating coils are affixed to the aluminum body to heat the aluminum body and transfer heat through the stainless steel into water. The composite of the inner and outer bodies provides efficient heat transfer for boiling water. The stainless steel resists any permanent adherence of residue to the heating module during the boiling process. Steam from the boiling water transfers through a mixing stack to surrounding air in the humidifier.Type: ApplicationFiled: May 27, 2003Publication date: January 8, 2004Inventor: Dov Z. Glucksman

Publication number: 20030230091Abstract: A user-programmable monitoring and dispensing system for controlling the dispensing of water vapor and various other media into an HVAC air stream in residential or commercial structures. The various media to be dispensed are preferably water-soluble, and mixed with the system water supply to be dispensed with the water vapor added to the HVAC air stream. These materials may be fragrances or aromas, intended to produce an aesthetic effect, or they can be agents capable of pesticidal, bacteriacidal, fungicidal or sporacidal effect for use as acute or prophylactic treatment for infestation. The dispensing system central processor is pre-programmed with a default concentration algorithm for each media to be dispensed. The concentration of media in aqueous solution is initially controlled by this default algorithm at each of several concentration levels, from lowest to highest.Type: ApplicationFiled: April 28, 2003Publication date: December 18, 2003Inventor: Scott Dillenback

Publication number: 20030085478Abstract: A system for reducing the temperature of exhaust gas in an incinerator or boiler equipment having an exceedingly small size and avoiding any difficulties caused by damage to the wall surface of a gas cooling chamber due to adherence of sprayed water droplets and deposition of dust. More specifically, pressurized thermal water with a temperature higher than a boiling point of water under atmospheric pressure is sprayed as temperature reduction water into high temperature exhaust gas Gh in a gas cooling chamber or an exhaust gas duct. The temperature reduction of exhaust gas and the removal of acidic gas in the exhaust gas are simultaneously achieved by spraying pressurized thermal water Wt containing an alkaline solution as temperature reduction water into high temperature exhaust gas Gh in the gas cooling chamber or the exhaust gas duct.Type: ApplicationFiled: November 22, 2002Publication date: May 8, 2003Applicant: TAKUMA CO., LTD.Inventors: Masayuki Kumada, Keiji Mukai

Publication number: 20030034573Abstract: A humidifier includes a housing, a fan assembly, a wick assembly, a first humidity sensor, a second humidity sensor, and a controller. The housing has an air inlet, an air outlet, and a reservoir for holding water. The fan assembly creates an airflow through the housing from the inlet to the outlet. The wick assembly is in fluid communication with the water in the reservoir and extends into the airflow within the housing for adding moisture to the airflow. The first humidity sensor measures an ambient air relative humidity and produces a first signal corresponding to the ambient air relative humidity. The second humidity sensor measures an outlet air humidity and produces a second signal corresponding to the outlet air humidity. The controller is in electrical communication with the first and second humidity sensors. The controller receives the first and second signals and performs calculations to produce an output signal.Type: ApplicationFiled: August 13, 2002Publication date: February 20, 2003Applicant: Hamilton Beach/Proctor-Silex, Inc.Inventor: Patrick T.

Patent number: 6355162Abstract: A wastewater aerating system that conditions air inlet to a blower of the system to adjust the condition of air discharged into the wastewater so as to increase the flocculation rate of suspended solids from the wastewater. The wastewater aeration system includes a conduit having an outlet submerged within a bath of wastewater to be treated, an air duct inlet in flow communication with a source of ambient air, a blower operable to cause air to pass through the air duct and through the conduit to be output through the conduit outlet into the bath of wastewater, and at least one heat exchanger installed in the air duct and adapted to condition, such as condense its vapor and sensibly cool, the air passing through the air duct. A method of treating a bath of wastewater is also disclosed.Type: GrantFiled: December 8, 1999Date of Patent: March 12, 2002Assignee: RWIInventor: Robert L. Longardner
