Robert J. Belock 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).

  • Elongated flexible detonating device
    Patent number: 4085676
    Abstract: There is provided an elongated, flexible unitary detonating device of indeterminate length for detonating a selected explosive material within a bore hole. The detonating device includes, in combination, a detonating cord capable of detonating the selected explosive material when initiated while in direct contact with the selected explosive and a flexible energy absorbing layer formed around and carried by the detonating cord. The energy absorbing layer is formed from an energy absorbent material and has a radial thickness sufficient to preclude detonation of the selected explosive in direct contact with the energy absorbing layer when the detonating cord is initiated. In addition, an arrangement is provided for allowing stripping of the energy absorbing layer from the detonating cord at any selected position along the detonating cord to expose a portion of the detonating cord.
    Type: Grant
