Patents by Inventor Roy E. Resh

Roy E. Resh 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).

  • Moisture tester with probe
    Patent number: 4399404
    Abstract: The tester has a probe to be inserted into granular or fluid materials for measuring instantly permittivity and temperature. The characteristics of materials are measured according to permittivity, the characteristics of moisture of grains being used as an example in the present embodiment.
    Type: Grant
    Filed: February 23, 1981
    Date of Patent: August 16, 1983
    Inventor: Roy E. Resh
  • Multiple-frequency permittivity tester
    Patent number: 4058766
    Abstract: As in prior testers, a capacitive cell in which material is placed to be tested is connected in a voltage divider circuit. However, signal generating means connected to the voltage divider applies voltages at different predetermined frequencies selected for the material being tested, and frequency selective means connected to the cell develop voltages at the applied frequencies having values dependent on the impedance of the filled cell at the respective frequencies. These voltages developed across the cell are applied to a computer that provides an output according to an equation that has been derived statistically from many samples of the material being tested for the substance or quality of the material being measured.
