Title: Anchoring Device for Tubing String
Inventor: OBREJANU MARCEL
IPC: E21B23/01
Filed: 1993-02-03
Abstract: A device anchors a tubing string within a stationary well casing against rotation in a predetermined angular direction. A housing is installed in-line in the tubing string. Anchoring mechanisms are spaced circumferentially about the housing. Each anchoring mechanism includes a recess and an anchoring member free-floating within the recess. The anchoring member has a fulcrum portion and a bite portion external to the recess. Retaining rings partially overlaying the recess prevent the anchoring member from escaping. A spring urges the anchoring member against the retaining rings and urges the bite portion to contact the well casing such that rotation of the tubing string displaces the anchoring member. Rotation of the tubing string in the predetermined direction seats the fulcrum portion in a seating structure within the recess and causes the bite portion to bite into the well casing, locking against further rotation. Rotation of the tubing string in an opposite direction displaces the anchoring member to a non-locking orientation in which the bite portion slides relative to the well casing.

Inventor: LATURELL DONALD R
IPC: H04B3/23
Filed: 1993-04-22
Abstract: An improved transformer-less electronic isolating transformer is obtained with an output subcircuit that outputs a controlled current rather thanvoltage. Specifically, the improved hybrid comprises an output drive subcircuit that receives an ac signal and creates a corresponding current that is passed to the line that supports two way communication. The subcircuit not only converts the applied voltage to current but includes means for effecting gain. Signals arriving to the hybrid from the line are applied directly to a near-end echo circuit that is also responsive to the signal applied to the output drive subcircuit. Both the input of the output drive subcircuit and the output of the near-end echo subcircuit are isolated with opto-isolators that employ photodiodes in their photo-voltaic mode.

Abstract: The provision of an electric rotating machine which can reduce the mechanical and thermal loads applied thereto. Coil arms (534, 537, 20b, 21b, 20d, 21d) and coil trunks (533, 536, 20e, 21e) are provided in roughly parallel orientation to the end faces of an armature core (520, 11) only through insulating rings or spacers (560, 590, 20a, 21a, 20c, 21c). Metal brush (910, 81) is disposed on coil arms, whereby the overall length of the armature can be remarkably shortened. In addition, a commutator, conventionally necessary, can be eliminated, whereby the length of the production process for the armature can be reduced.     Moreover, in an arrangement where projections (534c) of the upper coil arm are fit in holes of the insulating spacer, as the displacement of the upper coil arm towards the outer periphery is regulated, the length of axial protrusions of the upper coil arm from the end face of the armature core can be minimized. In addition, as extension portions (538, 20g, 20h) and of the coil trunks are strongly pressed against and fixed to the side of armature core by fixing members (570, 30), the resistance to the centrifugal force can be remarkably improved. Furthermore, as the extension portion of the lower coil arm is fit in a recessed part of the insulating spacer, the displacement of the lower coil arm in the axial direction towards the outer periphery can be prevented.
