Abstract: To provide stable, accurate time reference signals for control and operation of a well logging instrument (12), a temperature isolation enclosure (14) defines an internal cavity (16) for containing and protecting an electronic time base (10). An electronic timer (10) such as a crystal oscillator is located within the oven cavity (16) and is electronically stable at a predetermined temperature range slightly higher than the highest ambient temperature encountered within the wellbore. A heating element (18), control circuit (22), and a temperature sensor (24) are provided within the oven cavity (16) to maintain the timer (10) within the predetermined temperature range. An automatically energized cooling element (20) may also be provided within the oven cavity (16) for additional temperature control.

Abstract: A grinding machine provided with a spindle (5) rotating under the influence of a cantilever mounted rare earth permanent magnet motor (40). Hydrostatic fluid film bearings (41, 42) are provided between the ends of the spindle (5) and a bronze bearing (64, 65) to support spindle (5) in such a manner so as to eliminate wear. A single oil reservoir (20) is used to supply oil to the hydrostatic bearings (41, 42), as well as to the cooling jacket labyrinth (17) of the motor (40).

Abstract: A method for displaying seismic attributes in an open three-dimensional format is provided. The conventional two-dimensional variable-amplitude traces that represent the magnitude of a selected seismic attribute as a function of time are converted to three-dimensional format (21, 23, 25, 27, 29, 31, 33, 35, 37). The three-dimensional traces are hung beneath a model of their corresponding data-gathering stations (28) to provide a forest of seismic traces in a wire-frame environment (16). The open configuration of the seismic traces permits the interpreter to see a perspective view of the structure of the subsurface of the earth from any desired viewing angle.

Abstract: A three dimensional residual modeling operator is applied to seismic times that have been preprocessed by application of NMO and velocity independent DMO. The residual operator compensates for vertical velocity variation and anisotropy and its use precludes the need for ray tracing.

Abstract: A locking mechanism as shown in the figure for the contouring head assembly (108) of a belt grinding machine that employs multiple, parallel, abrasive grinding belts (62, 64; 66, 68; etc.) and back-up shoes (254) for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly (108) to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball (256) that is carried by the contouring head assembly (108) and a pivotable arm (156) is secured to a shaft (151) that is driven by a rotary actuator, that is powered by a hydraulic motor (150). The socket (266) engages the protrusion (256) to securely support one side of the contouring feed assembly. A hydraulic cylinder (158) forces a tapered plunger (258) against the pivotable arm (156) to enhance the locking action.

Abstract: A seismic energy source (10) for producing pressure pulses is disclosed. The source contains a substantially symmetrical main chamber (22) for storing compressed fluid. Two shuttles (24, 26) adapted to abut against each other are slideably placed around the housing (20) to sealingly enclose the chamber (22). A separate control chamber (46) for each shuttle is formed to urge its associated shuttle against the other shuttle when pressurized fluid is supplied to the control chamber (46). A separate firing chamber (80) is formed for each shuttle between the shuttle and the housing. The firing chambers are activated by the fluid from the main chamber (22) to simultaneously move both the shuttles (24, 26) away from each other to allow the compressed fluid to discharge from the main chamber (22) into the surrounding medium. A separate relief valve (81) is connected between each control chamber and the main chamber which allows the fluid from the control chamber to discharge into the main chamber when the control chamber pressure exceeds the main chamber pressure by a predetermined value.

Abstract: The present invention discloses, in certain aspects, a system and method for improving vibratory source seismic data in which a filter (C) is produced which converts a recorded seismic groundforce signal (118) (including harmonic distortion therein) into a desired short-duration wavelet which is used as the basis for generating a filter (122) for application to the seismic data (124).

Abstract: A seismic acoustic signal source (36) includes a hull (30) that has a wetted surface in contact with a body water (16). When underway, the draft of the hull (30) is substantially zero. An acoustic signal generator (36) is provided with a linear actuator (39) that is resiliently mounted in the hull. The linear actuator (39) is acoustically coupled to the bottom such that when the signal generator (36) is activated, the hull (30) radiates an acoustic wavefield (28) into the water (16).
