Abstract: A method for deployment of a geophysical sensor includes moving a ram having a ground penetrating bit at a movable end thereof to a selected geodetic position. The ram and the ground penetrating bit are extended to create a hole in a ground surface while measuring extension of the ram. The ram is retracted, and if the measured extension of the ram indicates successful creation of the hole, then the geophysical sensor is moved to a position beneath the ram and the ram is extended to urge the geophysical sensor into the hole.

Abstract: An apparatus and method for orienting and for coupling geophones relative to soil. A hammer device oriented to the vertical drives a head into the soil to generate a case opening. Vertical orientation of the case opening and depth automatically orients a geophone case to vertical and further controls the coupling of the geophone to the soil. Such combination facilitates orientation of the geophone to the selected compass heading and significantly reduces corrective data processing. Control over case opening placement in different soil conditions is automatically provided, and data regarding local position and orientation is recorded for future data processing. Operator errors are reduced and overall production efficiency is enhanced.

Abstract: A control valve assembly including a no-bleed pilot valve is disclosed. The pilot valve includes a pressure responsive valve adapted to move in connection with a control parameter, such as downstream fluid pressure. The pressure responsive valve selectively connects certain ports with upper and lower chambers of a control valve actuator so that the upstream and downstream fluid pressures may be used to operate the actuator.

Abstract: A fluid control valve having a valve body, a cage, and a flexible elastomeric diaphragm with a formed convolution to fully open the cage opening. An elastomeric diaphragm regulator with a flow diverter in the fluid flow path to reduce fluid flow separation and thereby reduce the required flow recovery area before pressure throttling. A raised knife edge seat located on the cage top in a position of stagnant fluid flow to reduce the build-up of contaminants on the seat. An elastomeric diaphragm regulator with a valve actuator coupled to a guided valve stem attached to the regulator diaphragm.

Abstract: A pressure unloading pilot operated fluid pressure regulator having a throttling element for controlling fluid flow. A pilot amplifier senses regulator outlet pressure and supplies suitable loading pressure coupled from an inlet supply pressure line through a variable flow restrictor to the throttling element. A check valve has a preset differential pressure defined between the check valve inlet and outlet and is mounted in parallel flow with the flow restrictor to limit the maximum differential pressure across the throttling element to the preset differential pressure of the check valve.

The conveyer units each include integral interconnecting cables having an hermaphroditic connector at each end, analog seismic sensor inputs and signal processing circuitry disposed within a watertight housing forming part of the cables. The circuitry includes analog-to-digital conveyers connected to the analog inputs, a buffer for digitized signals transmitted to one converter unit from other converter units interconnected to the conveyer unit opposite to the control unit connection, a digital transceiver for retransmission of digitized sensor signals and the buffered signals at a first data rate to the control unit. The control unit includes a second buffer for signals from the conveyer unit and for signals retransmitted from other control units serially codected to the control unit.
