  • Patent number: 7021116
    Abstract: The invention provides press brake and press brake tooling technology. Certain embodiments of the invention provide a press brake tool that has an elongated, retractable safety key. In certain embodiments, the invention provides click-in/slide-out press brake tools. In some of these embodiments, the tool has a safety key defining a flat (i.e., a planar wall section/planar surface) that is adapted for sliding along a surface of a tool holder when the tool is dismounted from the holder by moving the tool horizontally out of the holder. In certain embodiments, the flat has a longitudinal length of at least about 0.008 inch (in some cases, at least about 0.010 inch, at least about 0.015 inch, or at least about 0.020 inch), ranging up to the full longitudinal length of the tool. In certain embodiments, the invention provides a press brake tool and a tool holder in combination. Finally, the invention in some embodiments provides methods of press brake operation.

  • Patent number: 6712758
    Abstract: A grounding system for a fiberscope utilizing an electrically conductive braid surrounding at least a portion of a flexible hollow tube containing fiber optic bundles. The fiberscope also includes an electrically conductive member surrounding the bundle end. The system further possesses connections between the electrically conductive braid and the end member. An electrically conductive ferrule underlies and links the fiberscope housing and the electrically conductive braid. A conductor connects to the ferrule, extending to the exterior portion of the housing for accessibility to the user.

  • Patent number: 6478478
    Abstract: A fiber-optic connector utilizing a first tube for receiving a source of light and a second tube separated from the first tube enclosing an optic bundle. A first guide surrounds the first tube and positions the first tube along an axis to place the same adjacent the second tube. A second guide determines radial orientation of the first tube relative to the second tube by engaging planar surfaces on the second guide.

  • Patent number: 4439675
    Abstract: A moisture and density gauge which combines sources of gamma and neutron radiation in a casing which is placed in the medium being analyzed. The gauge includes detectors for the gamma and neutron radiation being placed in end to end configuration within the casing such that the neutron detector is placed between the gamma radiation detector and the source of gamma radiation.

  • Patent number: 4146796
    Abstract: An apparatus for determining the depth of a radiation source within a body of material utilizing a radiation source holder moving the radiation source within the body. A plurality of switches have contacts that are fixed in relation to the movement of the radiation source within the material. Trigger means activates a particular switch at a preselected depth of the radiation source. Means for indicating the activation of a switch would thus produce a signal as a representative of the depth of the radiation source.
