  • Water motion powered seismic energy source and method for seismic surveying therewith
    Patent number: 8353383
    Abstract: A seismic energy source includes an inlet aperture and an inlet pipe in fluid communication with an outlet of the inlet aperture at an inlet end of the inlet pipe. The inlet pipe is in fluid communication with an accumulator at an outlet end of the inlet pipe. An outlet pipe is in fluid communication with the accumulator at an inlet end of the outlet pipe and is connected to an outlet valve at an outlet end of the outlet pipe. The outlet valve is actuated by fluid pressure in the outlet pipe. An actuation pressure of the valve, and diameter, length and material properties of the outlet pipe are selected to cause a reflected water pressure wave resulting from closure of the valve to travel within the outlet pipe at a selected velocity. Motion of the seismic source through the water provides water pressure to operate the source.

  • Electrical resistors
    Patent number: 4322710
    Abstract: An electrical resistor comprises a tube of resistive material having a closed end. An electrical connection is made to the open end of the cylinder, and a further connection comprises a conductor passing through the open end of the cylinder and connected to the closed end. A pair of voltage-measuring connections are made to the outer surface of the cylinder.
