Mud pulser with poppet valve, having linear displacement determination means

ActiveUS20160208953A1Slow changeReduce non-linearityOperating means/releasing devices for valvesSurveyServo actuatorEngineering

A measurement-while-drilling servo-actuator for use in mud-pulse telemetry, which determines linear position of a poppet valve therein without counting revolutions of a stepper motor which positions said poppet valve. A sensor senses a magnetic field intensity value, or an inductance value, which is proportional to the position of the poppet valve relative to the sensor. A look-up table of reference outputs corresponding to known position of the poppet valve is used to determine the position of the poppet valve. A method of determining a position of a poppet valve in a mud pulser is further disclosed.

Method and apparatus for releasable fastening and for modification of the relative positions of two components with respect to one another

ActiveUS20050047857A1Eliminate disadvantagesRopes and cables for vehicles/pulleySighting devicesEngineeringMechanical engineering

A method and an apparatus for releasable fastening and for modifying the relative position of two components (1, 1′, Bf, G; 2, 2′, Bk, Br), which have a common connecting surface forming a contact surface (5, 5′), is described. Two screws (3), which in coaction with specially configured V-shaped notch zones (9a₁, 9a₂; 9b₁, 9b₂; 9a₃, 9a₄; 9b₃, 9b₄) permit a relative positioning in zero-backlash and accurately aligned fashion, serve as the fastening means. It is thereby possible to perform a linear displacement and/or a rotation and/or a tilt in simple fashion.

Damaged cable/concentrated load recognition method on basis of linear displacement angle monitoring

InactiveCN103604647AStructural/machines measurementApparatus for force/torque/work measurementLinear relationshipLinear displacement

The invention relates to a damaged cable/concentrated load recognition method on the basis of linear displacement angle monitoring, which is based on angle monitoring. Bracket linear displacement, cable structure temperature and ambient temperature are monitored to determine whether a mechanical calculation reference model of the cable structure needs to be updated, thereby obtaining a mechanical calculation reference model of the cable structure counting in the bracket linear displacement, cable structure temperature and ambient temperature; and the calculation is performed on the basis of the model to obtain unit-damage monitored quantity value change matrix. The noninferior solution of the evaluated object current nominal damage vector is calculated according to the near linear relationship among the monitored quantity current value, monitored quantity current initial value vector, unit-damage monitored quantity value change matrix and unknown evaluated object current nominal damage vector, thereby eliminating the influence of interference factors and recognizing the concentrated load variation and damaged cable in the presence of bracket linear displacement and temperature change.
