    摘要: A poppet-type check valve for controlling fluid flow, and including a valve housing having an interior and first and second ports therein communicating with the interior of the valve housing for permitting fluid flow from an upstream side to a downstream side thereof. At least one valve assembly is disposed within the interior of the valve housing for controlling the fluid flow therethrough. The valve assembly includes a valve seat positioned in the interior of the valve housing and a seal retainer positioned in the interior of the valve housing downstream from the valve seat and mounted on a stem. The seal retainer and the stem are axially moveable away from the valve seat in response to fluid flow in a downstream direction at a predetermined flow rate, and axially moveable towards and into sealing engagement with the valve seat in response to a downstream fluid flow at a flow rate less than the predetermined flow rate. A plurality of springs is allowed to compress past the position of neutral load for the purpose of elongating the stroke of the poppet. The elongated stroke results in enhanced flow performance.

    摘要: An apparatus for borehole electric field telemetry includes a source of modulated voltage or current, at least one axially extending collar connected between pipe sections in a pipe string, and a system of insulated wireline components providing electrical connections, insulated from drilling fluids, between the ends of the one or more aforementioned insulative collars in the pipe string, to transmit the voltage or current. The source of modulated voltage or current comprises an electrical pulse-producer for producing short duration pulse wave forms selected to obtain optimum transmission characteristics in the underground formation. The electrical connections are to the drillstring, and there are upper and lower instrument housings associated with the electrical connections, which are upper and lower connections. The housings are supported within the pipe string, the upper housing located above at least one of the insulative collars, and the lower housing projecting below the insulative collar. The pulse-producing means is located within at least one of such housings.

    摘要: A telescopic mast is provided in kit form with stays wound on reels in a predetermined order. This order is such that when erecting the mast it is only necessary to walk between the mast and pegs fixed into the ground and not between two pegs at a distance from the mast. This minimizes the amount of walking which is necessary in erecting the mast. Clamps between sections are formed from a strap around the outer of two concentric sections. The ends of the strap are secured together and attached to a member with a pressure face. A camming device between this member and the mast which acts against the pressure face and the mast enables the strap to be tightened thus gripping the outer mast portion against the inner mast portion. The top section of a telescopic mast is less inherent rigidity than the bottom section and this it is preferable to construct it from material with a greater resistance to longitudinal bending than the lower section and to vary the resistance of the intermediate sections accordingly.
