Rotary Patents (Class 73/152.34)
  • Patent number: 8836534
    Abstract: An autonomous drilling rig (200), including a carriage including a mast (204), a rotary head (202) configured to traverse up and down the mast (204), and a wireless transmission system. The wireless transmission system includes a wireless transmitter (208) mounted on the rotary head (202) and configured to send a wireless signal to a wireless receiver (210). The wireless transmitter (210) includes a first connector (209) configured to engage with a first sensor, wherein the sensor measures at least one operating parameter. The wireless transmission system further includes the wireless receiver (210) configured to receive the wireless signal from the wireless transmitter (208), wherein the wireless signal comprises the at least one measured operating parameter, and a display unit (610) operatively connected to the wireless receiver (210) and configured to display the measured operating parameter.

  • Patent number: 8800384
    Abstract: Flowmeters and methods of measuring a fluid flow or manufacturing flowmeters are presented. A flowmeter has a tool body and one or more spinner arms configured to extend with a first end away from the tool body and a second end joined to the tool body, when deployed to measure a fluid flow. Each spinner arm includes a helical blade configured to rotate due to a fluid flowing substantially parallel to a longitudinal axis of the tool body, around a rotation axis between the first end and the second end.

  • Publication number: 20130298663
    Abstract: A liquid (6) flows through a wedge meter (13). The density of the liquid (6) is measured with a Coriolis meter (14). Density as measured by the Coriolis meter (14) is used in calculating the volume flow of fluid (6) through the wedge meter (13).

  • Publication number: 20110162446
    Abstract: A fluid flow meter is responsive to measured torque force imposed by fluid flow over a static impeller. Exponential torque relationships imposed upon a static torque shaft by fluid flow over a static impeller are linearized by a resilient torque shaft restraint and translated to flow rate values by torque measuring means.

  • Patent number: 6951262
    Abstract: Methods and apparatus for suppression of wave energy within a fluid-filled borehole using a low pressure acoustic barrier. In one embodiment, a flexible diaphragm type device is configured as an open bottomed tubular structure for disposition in a borehole to be filled with a gas to create a barrier to wave energy, including tube waves. In another embodiment, an expandable umbrella type device is used to define a chamber in which a gas is disposed. In yet another embodiment, a reverse acting bladder type device is suspended in the borehole. Due to its reverse acting properties, the bladder expands when internal pressure is reduced, and the reverse acting bladder device extends across the borehole to provide a low pressure wave energy barrier.
