20080089676 - Microstructured apparatus for heating a fluid: In a microstructure apparatus for heating and atomizing a fluid with an inner body received in an outer tube, circumferential microstructure passages are formed into the inner surface of the outer tube or the outer surface of the inner body so as to form a flow passage which is provided... Agent: Klaus J. Bach

20080085103 - Dispersion device for dispersing multiple volatile materials: A dispersion device for dispersing volatile materials includes a housing and a plurality of receptacles containing volatile material therein. The device also includes a means for generating or permitting two or more airflows that exit the housing and a switch for adjusting the airflows with respect to speed or path.... Agent: S.c. Johnson & Son, Inc.

20080085104 - Polyolefin sealing gasket: A semi-rigid polyolefin water heater gasket is employed to increase the speed and reduce the cost of installing a urethane leakage barrier between an inner water heater vessel and an outer shell. The gasket comprises a strip of polyolefin material that is wrapped around the exterior of an inner water... Agent: Charles Y. Lackey

20080085105 - Multi-passage electric heater using ceramic foam as a diffuser and method of use: A multi-passage electric heater for heating a gas flowing through the passages uses electric heating elements disposed in the passages for gas heating. One of both of the inlet and outlet of the heater includes a ceramic foam material as a diffuser. The diffuser on the inlet side effectively distributes... Agent: Clark & Brody

20080085106 - Two-stage water heater assembly: A two stage water heater assembly comprising a tankless stage, which preheats water, and water storage tank stage, which stores the preheated water and maintains the water at a desire temperature. This water heater assembly provides the user with an unlimited supply of hot water on demand while doing so... Agent: Timothy B. Smith

20080080844 - Apparatus and method for detecting condition of a heating element: A control for an electric water heater detects a condition of a heating element when the heating element is not being energized. A switching module is operable to interrupt power to the heating element, which de-energizes the heating element. A detector module detects the condition of the heating element when...
