Patents by Inventor Barry Watson

Barry Watson 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: 4666644
    Abstract: Asymmetrical layered structures such as asymmetrical films are disclosed. The main body section contains a multitude of pores (voids). A thin surface skin is free of pores. The entire structure is fabricated from a polyalkylene sulfone resin in which the alkylene moiety contains 6 to 18 carbon atoms. Processes for preparing the structures also are disclosed. The structures are semi-permeable to gases and are used as membranes to enrich the oxygen content of oxygen/nitrogen mixtures.
    Type: Grant
    Filed: September 23, 1985
    Date of Patent: May 19, 1987

  • Patent number: 4172770
    Abstract: An electrochemical system using a flow-through electrode design employing a dual separation method to lower electrode poisoning due to large chemical species and interference current due to small electroactive species is disclosed. The system includes a fluid inlet to a reaction chamber and a fluid outlet from the chamber, with the chamber in contact with an electrode system. The electrode is protected from poisoning and interference by a membrane system comprising a semipermeable membrane having well defined pore ranges therethrough which allow diffusion of only selected size small molecules. A unique sample stream flow control coupled with the size selective membrane combine to remove large, or macromolecule poisoning species and substantially reduce small species interference at the active surfaces of the electrode means.

  • Patent number: 3995835
    Abstract: An inline magnetic mixer for flowing fluids. A magnetic particle is contained within a flow tube through which a fluid passes. A coil made of electrically conductive material is positioned in close proximity to the flow tube and outside the flow tube. A low voltage, oscillating electrical supply energizes the coil. This sets up an oscillating magnetic field within the flow tube which causes the magnetic particle to oscillate longitudinally within the flow tube, thereby mixing the fluid stream passing through the flow tube.
