Patent number: 4334592Abstract: A hydraulic drive system for an underwater vibrator has a hydraulically driven mass for generating a seismic wave into the seabed. The hydraulic drive system for the vibrator is accomplished by filtering sea water, conveying the filtered sea water to the hydraulic pump where the sea water under pressure is supplied through a control valve to the hydraulic vibrator. The output from the control valve is coupled to the sea water. The hydraulic system provides hydraulic fluid which will not need to be cooled, thereby eliminating the normal cooling system along with several necessary accumulators and sump which are used in a closed hydraulic system.Type: GrantFiled: December 4, 1980Date of Patent: June 15, 1982Assignee: Conoco Inc.Inventor: Delbert W. Fair

Patent number: 4333499Abstract: Apparatus for dissipating the pressure of a confined fluid has a housing with a sidewall in a substantially circular cross-sectional configuration with a top and bottom. Inlet means is formed into the sidewall so that the axis of the inlet is tangent to a diameter of the sidewall. An outlet extends through the bottom and an opening extends through the top. High pressure fluids entering the inlet form a vortex around the sidewall and between the top and the bottom and pass out the outlet under low pressure. Air is introduced through the openings in the top to prevent cavitation within the housing. A device may be coupled to the outlet to reduce the velocity of the fluids leaving the outlet.Type: GrantFiled: April 15, 1980Date of Patent: June 8, 1982Assignee: Conoco Inc.Inventors: Jeffrey L.

Patent number: 4308597Abstract: A method for removing an undesired surface wave from a reflected wave in a method for seismic exploration is accomplished by placing first and second detector arrays at a location on the surface of the earth in the direction of movement of the surface wave. The array has a length less than the length of the shortest wave length of the interfering wave to be eliminated. Signals from both arrays are recorded and processed by first adding the received signals to form a first output, subtracting added signals to form a second output, shifting one of the output signals by 90.degree., adjusting its amplitude and subtracting the phase shifted and adjust signal from the remaining signal thereby removing the surface wave.Type: GrantFiled: December 19, 1979Date of Patent: December 29, 1981Assignee: Conoco Inc.Inventor: Harold A.

Patent number: 4281547Abstract: The integrity of mine roofs and rock bolts is tested by determining the natural frequencies of the roof and bolt. The roof is struck at a plurality of locations and the resulting vibrations sensed with accelerometers. The output of each accelerometer is separated into a plurality of signals of different frequencies by a comb filter having selected band passes. The amplitude of the outputs of each of the band passes of the filter are used to determine the condition of the roof and bolt adjacent each accelerometer. The high amplitude signal resulting from the initial impact of the striking implement is electrically gated from the accelerometer output.Type: GrantFiled: May 10, 1979Date of Patent: August 4, 1981Assignee: Conoco, Inc.
