  • Patent number: 11555356
    Abstract: A snubber device for reducing shocks and vibrations in a downhole tool. The snubber includes a main body extending between upper and lower connector ends. The main body is defined by one or more cut-out portions. One or more elastomeric elements are held within the one or more cut-out portions. The cut-out portions provide flexibility to the main body. The elastomeric elements absorb shocks and vibrations and are conveniently replaceable when excessive wear reduces their shock and vibration absorbing capacity.

  • Patent number: 11002367
    Abstract: A valve is provided which is based on a stationary sleeve. The stationary sleeve includes at least one coil in communication with an electrical power source and one or more openings in the body of the stationary sleeve open to the hollow interior of the stationary sleeve. The valve has a microcontroller configured to control flow of electrical current independently to the coil and an inner sleeve configured to fit within the stationary sleeve. The inner sleeve has an internal or external magnetized portion and one or more ports open to the hollow interior of the inner sleeve. The inner sleeve is moveable within the stationary sleeve under power provided by a magnetic field generated by the electrical current passing through the coil to either align the ports with the openings to open the valve or to remove alignment of the ports with the openings to close the valve.

  • Patent number: 10224684
    Abstract: A process for manufacturing a rotary connector device for making a plurality of electrical connections includes construction of a male connector component and a female conductor component. The male connector component is constructed by providing a male underlying body having a plurality of longitudinal channels formed therein for holding male conducting wires. Alternating separate male conducting rings and separate male insulating rings are placed on the underlying body with each separate conducting wire occupying a separate channel. The female conductor component is constructed by providing a female body with a central bore having at least one groove formed therein for holding female conducting wires. Separate alternating female conducting rings and separate female insulating rings are installed on a rod and transferred to the central bore of the female body with the female conducting wires occupying the groove.

  • Patent number: 9879528
    Abstract: An actuator for a mud pulse telemetry tool. The actuator includes a solenoid-based servo valve with a coil shaft responsive to data transmitted by a data processor. The coil shaft is movable between an extended position and a retracted position. Movement of the coil shaft to the extended position moves a poppet to close a servo orifice thereby preventing mud flow to a main mud pulse valve of the mud pulse telemetry tool. Movement of the coil shaft to the retracted position moves the poppet to open the servo orifice thereby allowing mud flow to actuate the main mud pulse valve. The poppet is connected to a poppet shaft and the poppet shaft cooperates with the coil shaft in a slide hammer mechanism to amplify force provided by the coil shaft against the poppet shaft with linear movement of the coil shaft to the extended position and to the retracted position.
