Patents by Inventor William F. Troxler

William F. Troxler 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: 11776703
    Abstract: A gauge is provided for measuring one or more characteristics of a construction material such as a road surface. The gauge includes a detector, a base that carries the detector, and a source housing carried by the base and defining a shield material circumferentially extending inwards. A source rod is positioned within the housing and carries a source that is translatable between a shielded position within the housing and a measuring position external of the housing. The source rod has a source shield on the top thereof and a shield material spaced-downwardly from the source such that the source is completely enclosed when contained within the base.
    Type: Grant

  • Patent number: 6617599
    Abstract: The invention provides a method and apparatus for facilitating calibration of a nuclear gauge by automating the movement of a source rod between a plurality of source rod positions. The apparatus can include a linearly moveable member, such as a threaded rod, a motorized linear actuator, such as a stepper motor, and a source rod grip attached to the linearly moveable member for affixing the source rod to the member.

  • Patent number: 4979197
    Abstract: The present invention provides an apparatus and method for dynamically measuring the density of soil, asphaltic material and the like during the compaction of the material. The gauge includes a nuclear radiation source and a nuclear radiation detector means which are mounted in spaced relation from the surface of the test material to form an air gap therebetween. The gauge also includes means for measuring the size of the air gap between the test material and the source and detector system, and means to compensate for the effect of the size of the air gap to thereby obtain the density of the test material.
