  • Patent number: 10370899
    Abstract: In accordance with an embodiment of the disclosure, a method includes detecting a first parameter indicative of lateral movement of a top drive system with respect to a rotational axis of the top drive system with a first plurality of sensors and detecting a second parameter indicative of lateral movement of the top drive system with respect to the longitudinal axis of the top drive system with a second plurality of sensors. The first parameter is different from the second parameter. The method also includes transmitting the first parameter and the second parameter to a monitoring system and comparing the first parameter to a first threshold value and comparing the second parameter to a second threshold value with the monitoring system. Detecting the first parameter and the second parameter includes detecting lateral movement of a mud saver valve configured to flow mud through a sealed passage.

  • Patent number: 9784054
    Abstract: A drilling system includes a multi-function sub configured to be coupled to a top drive of a drilling rig and configured to be coupled to a tubular in order to selectively transfer a torque from the top drive to the tubular. The multi-function sub includes a torque sensing component configured to measure the torque provided from the top drive to the tubular via the multi-function sub, a clutch configured to suspend a transfer of torque from the top drive to the tubular when the clutch is released, and a clutch actuator communicatively coupled to the torque sensing component and configured to release the clutch when the torque measured by the torque sensing component is greater than a threshold torque value. The multi-function sub also includes a compensator configured to enable the multi-function sub to move the tubular in an axial direction relative to the top drive.

  • Patent number: 9650880
    Abstract: The present disclosure is directed to systems and methods for rotating a drill string to overcome issues related to static friction during drilling. An embodiment includes a drive system configured to rotate the drill string through variable angular displacements and at variable rotation speeds based on control signals received by the drive system, and a control system configured transmit the control signals to the drive system, wherein the control system is configured to generate the control signals based on pipe characteristics within the drill string and friction values associated with the drill string to establish a rotation pattern of the drive system to approach a desired effective reach of surface torque generated by the drive system on the drill string.

  • Patent number: 7703636
    Abstract: A device and method are provided for dispensing a quantity of food to be cooked. The device includes a freezer, a storage container located in the freezer, means located in the freezer for dispensing a predetermined quantity of food from the storage container into a secondary container, and means for dispensing the quantity of food from the secondary container to a location outside the freezer. The means for dispensing a predetermined quantity of food may be, for example, a magazine with dual spiral flights for dispensing food items one at a time, or a vibratory conveyor cooperating with a device for determining a quantity of food in the secondary conveyor and means for terminating the dispensing when a predetermined quantity of food is sensed. The secondary container may have an opening in its bottom and be movable laterally to align its opening with an opening in the freezer.

  • Patent number: 7343719
    Abstract: An automated food processing system and method is provided that allows food to be dispensed, fried and packaged in a suitable container, which may be an individual portion-sized container. In one embodiment, the system includes separate automated modules for dispensing, frying and packaging the food. In one embodiment, an automated dispensing device dispenses a predetermined portion of food from a bulk storage container or food dispensing magazine. Food is dispensed from the automated dispensing device to an automated fry device that can include at least one circular fry wheel having a plurality of food containing compartments. After the food is fried it is dispensed from the fry device to an automated packaging device. The automated packaging device dispenses food to a container that may be an individual portion-sized container that is retrieved, erected and held into position for filling by an automated container handling system.
