Thomas B. Margittai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5473892
    Abstract: A fluid pressurizing unit for generating high pressure fluid by utilizing the water weight changes caused by the presence of a wave crest or wave trough directly above the apparatus. The apparatus is positioned under the surface of a body of water having waves and has a plunger having a flat disk at its upper end. The plunger moves vertically with respect to a rigidly mounted cylinder, which defines a fluid chamber having a cross sectional area less than the surface area of the flat disk. A conduit, in fluid communication with the fluid chamber, conducts water from the body of water, or fluid from an inlet tank, to the fluid chamber and pressurized fluid to a collection tank. Inlet and outlet check valves insure that fluid does not flow from the collection tank to the fluid chamber, or from the fluid chamber to the water source or inlet tank. Preferably, a plurality of such units are arranged hydraulically in parallel with one another.

  • Patent number: 5471913
    Abstract: A processor for heating and mixing a liquid product, without changing the chemical and other characteristics of the product, includes a plurality of planar elements, or plates, having a thickness sufficient to be mechanically machined and each having a first fluid flow path defined by a groove formed on the top surface of the planar element. Each planar element includes a second fluid flow path which is isolated from the first fluid flow path and defined by a passage extending through the planar element from the top surface to the bottom surface. A mounting system or device mounts the planar elements adjacent one another so that the bottom surface of one planar element is in contact with the top surface of the planar element just below it. In addition, the plates are aligned such that a first fluid, such as a heating medium, will flow between a first and second planar element and a second fluid, such as a liquid product being heated, will flow between a second and third planar element.

Inlet and outlet check valves insure that fluid does not flow from the collection tank to the fluid chamber, or from the fluid chamber to the water source. Preferably, a plurality of such units are arranged hydraulically in parallel with one another. In this embodiment, a single collection tank collects pressurized fluid from the individual units.

  • Patent number: 4215743
    Abstract: This invention is a heat exchanger device which is an improvement on U.S. Pat. No. 3,612,002, Liquid-Heating Apparatus by the same inventor. The invention is a heating or cooling apparatus for liquids which lends itself to quick disassembly and reassembly and which contains a hollow double flange inlet for the introduction of heating medium, a double helix to lead the heating medium inside of hollow concentric cylinders, and a hollow flange with two chambers for the introduction of fluid. In addition, the apparatus is modified by rounding its internal structure to allow coating of its internal surface with a corrosion resistant film such as glass, plastic or the like. A further modification of the invention comprises the construction of cylindrical elements with spiral paths therethrough.
