Water Patents (Class 219/688)
  • Patent number: 5387780
    Abstract: An apparatus and method for heating water using a microwave powered boiler. The apparatus consists of a three cabinet arrangement which permits the dry incorporation of wave guides and the tunneling of microwave energy completely around and into a seamless water chamber. The apparatus can be adapted to provide a hydronic heating system, a forced hot air heating system, a tankless domestic hot water supply and a hot water heater.

  • Patent number: 5336869
    Abstract: The present invention is an apparatus for manipulating fluid flow. The apparatus includes a member having a channel through which fluid flows and at least one opening of a predetermined diameter in communication with the channel. The opening controls the fluid flow thereacross. At least a portion of the member is in thermal contact with the opening and is made of a material reactive with electromagnetic energy. There is also a device for providing electromagnetic energy. The providing device is in communication with the portion of the member reactive to electromagnetic energy such that the electromagnetic energy heats the portion of the member. The present invention also pertains to an apparatus for restricting fluid flow. The restricting apparatus includes a member having a first surface, a second surface opposing the first surface and an opening between the first and second surface for restricting the fluid flow therethrough. The member is made of sapphire or ruby.

  • Patent number: 5302794
    Abstract: Microwave energy is used to dry air. Moist air is forced through an absorbing or adsorbing material and the material is regenerated by heat from one or more microwave transmitters. The drying material is placed in a magazine, the greater walls of which permit air to pass and at least one of the walls reflecting microwaves. A drying room placed adjacent the magazine contains at least one microwave transmitter. Moving bodies can be used to spread the waves over the magazine surface for even drying. Several combinations of the above components can be used together in several ways based upon the ground components.

  • Patent number: 5286949
    Abstract: An apparatus and method for providing heated hair rollers wherein the rollers are suspended vertically in a heating chamber of a housing, an amount of water is introduced into the chamber and heated to generate steam which surrounds the rollers and condenses thereon heating and moistening the rollers which may then be removed and applied to a person's hair. The rollers are suspended by a horizontal plate within the housing which defines a steam chamber between the plate and the bottom of the housing. The plate has a plurality of holes sized to allow passage of the rollers. Each hair roller has a head portion which is larger in diameter than the respective hole whereby the rollers are suspended from the plate within the steam chamber such that the head portion of each roller remains outside of the heating chamber to provide a relatively cool handle for easy manipulation of the heated and moistened rollers.
