Patents by Inventor Allen F. Reid

Allen F. Reid 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: 6080309
    Abstract: The method of separating impurities from an aqueous solution by means of rotating the aqueous solution at high speeds until a high pressure and a high temperature is reached. At that time the impurities are separated from the solution. The aqueous solution is kept at high temperatures and pressures until the impurities are separated from the liquid. Preferably, a device providing a centrifugal force, such as a centrifuge, is used to achieve the high temperatures and pressures which should preferably be no lower than 705.4.degree. F. and 3,208 psi, respectively.
    Type: Grant
    Filed: May 11, 1995
    Date of Patent: June 27, 2000
    Inventors: Allen F. Reid, Albert H. Halff
  • Patent number: 5688399
    Abstract: A mechanism for converting impurities or contaminants in a fluid to a non-hazardous or less hazardous condition by raising the fluid to a supercritical state. This is accomplished by a rotatable mechanism having a reaction chamber adapted to receive the fluid and by rotating the rotatable mechanism at a high speed to cause the temperature and pressure of the fluid in the reaction chamber to reach the supercritical state.

  • Patent number: 5082564
    Abstract: The method and mechanism for desalinating seawater and brackish water in which saline water is divided into inside and outside streams. The inside stream is moved through the inside of a transport membrane. The outside stream moves across the outside of the membrane. Ions cross the membrane from one stream to another and more ions are moved from the inside stream to the outside stream than are moved from the outside stream to the inside stream. The process is powered by an Na,K-pump in which Na.sup.+ ions are moved from the inside stream to the outside stream and K.sup.+ ions move in the opposite direction. After the inside stream leaves the transport membrane, the K.sup.+ ions are replaced by Na.sup.+ ions by a suitable ion exchanger.

  • Patent number: 4586339
    Abstract: In heat transfer from a warm water source, efficiency is improved in a thermal energy conversion (TEC) by increasing the temperature of heat supplied to a turbine system substantially above the water temperature. This temperature increase is accomplished in a separate system by reacting gaseous ammonia with water to produce sensible heat at a high temperature; the ammonia is later fractionated from the water using lower temperature heat from the existing heat source. A single-stage temperature increase system (TIS), may be used or there may be an addition of a second stage for raising the temperature of the heat supply even higher.

  • Patent number: 4254743
    Abstract: An improved internal combustion engine and method of operation are disclosed. A method and a means are described for conserving mechanical energy in the engine cylinder during the combustion portion of the engine cycle by automatically adjusting the engine cylinder volume.

  • Patent number: 4161210
    Abstract: The process accumulates heat from a relatively low temperature source to support an endothermic chemical reaction, partially separates the products of the reaction from the reactants, and then releases the accumulated heat in the reverse exothermic chemical reaction at a higher temperature simultaneously restoring the original chemical composition. The forward and reverse chemical reactions are slow enough to prevent substantial reaction during the separation and transfer of the chemicals, but they may be speeded by catalysts within the reaction chambers. The chemicals are separated by standard procedures such as sorption-desorption, distillation, freezing and melting, precipitation, extraction, centrifugation, and reactions with other materials.
