Patent number: 7057140Abstract: An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a substrate to heat the substrate which in turn heats the water flowing through the heating chamber. The heater is highly efficient due to the direct contact of the wet heating surface with the water and provides a smooth seamless inner heating surface by eliminating the need to pass electrical leads into the wet region of the heater. This virtually eliminates the risk of leaks in the water heater due to bulkhead fittings. The invention further eliminates the need for a heating element to be contained in the inner wet region of a spa heater, thereby reducing the risk of corrosion.Type: GrantFiled: June 29, 2001Date of Patent: June 6, 2006Assignee: Balboa Instruments, Inc.Inventor: Robert Pittman

The fluid circulates through numerous tubes positioned within the tank having respective inside surfaces which are each provided with a heating unit therein for collectively heating fluid as the fluid passes between each respective inside surface and heating unit. The tubes have dimples formed therein for more efficiently heating the fluid.Type: GrantFiled: May 1, 2002Date of Patent: August 10, 2004Assignee: Watlow Electric Manufacturing CompanyInventor: George B.

Patent number: 6721497Abstract: An apparatus for heat generation includes a vessel having a working chamber with a flow of working fluid passing therethrough. A source of pulsed light and a light-reflecting surface wettable by the working fluid are situated within the working chamber. A thermal energy is released into the working polar fluid by the pulsed light irradiation of the working fluid in the vicinity of the light-reflecting surface. The released thermal energy is continuously removed from the vessel by the flow of working fluid.Type: GrantFiled: June 10, 2002Date of Patent: April 13, 2004Assignee: Future Energy Corp.,Inventors: Valentin A. Gruzdev, Pavel V. Efremkin

Publication number: 20040062532Abstract: A device (10) for isolating a surface for welding in an underwater location or in high fire risk areas. The device comprises a housing (27) which is arranged to be mounted on the surface and a sealing means (30) to provide a seal between the housing and the surface. The housing (27) is provided with a sealed inlet (50) for receiving a welding apparatus, a fluid inlet (32) for the passage of gas into the housing, and a fluid outlet (34) for the passage of gas and/or liquid out of the housing. A heating means FIG. 3 is not figure) for providing heated gas to the fluid inlet is also provided. In use, an ingress of heated gas through the fluid inlet (32) facilitates an egress of gas and/or liquid, contained in a space defined by the housing and the surface, through the fluid outlet (34) in the housing. In this way an in situ dry gaseous environment is provided for welding the surface.Type: ApplicationFiled: June 16, 2003Publication date: April 1, 2004Inventor: Clive Graham Langley

Publication number: 20040018010Abstract: A vehicle or stationary liquid, water or oil tank heater teaches that a hot fluid may be passed through a metal body placed in the water piping or in the vacuum piping, thereby melting any ice in the system and preventing further freezing. The system may be advantageously used with manifolds, valves, scrubbers, pipes or the water tank itself. The coolant flow path may be optimized for ease of production and/or efficient heat transfer. The invention may be used with an external source of hot liquid, or it may be used with a cuff which may slipped over any of a variety of devices in need of de-icing.Type: ApplicationFiled: March 26, 2003Publication date: January 29, 2004Inventor: William Garland Latham

Patent number: 6643454Abstract: A temperature maintenance heater assembly for maintaining the temperature of a heated fluid circulating through piping of a bath, including a pipe section, a base plate, a control assembly, a heater assembly cover, and a heating element. The heater element is mounted within the pipe section. The control device assembly is electrically connected to the heater element and to a source of power. The control assembly includes a flow switch operable to interrupt the supply of power to the heater element under certain operating conditions, such as when the fluid flow through the pipe section is less than a pre-selected threshold value. By interrupting the supply of power to the heating element under certain operating conditions, the temperature maintenance heater assembly provides operational safety measures to the user.Type: GrantFiled: October 1, 2002Date of Patent: November 4, 2003Assignee: Alpha-Western CorporationInventor: Gary P.
