  • Patent number: 9845608
    Abstract: A valve 10, for relieving ground water pressure on a swimming pool for containing pool water. A body 30 defines a flow path. An element 20 is mounted to be moved in a direction from a position, in which at least one feature 22 of the element co-operates with at least one feature 33 of the body to form a sealing arrangement to block the flow path to retain the pool water, to a position in which the flow path is open to allow ground water into the swimming pool. The sealing arrangement defines an effective area over which the ground water pressure acts to drive the element in the direction, and an effective area over which pool water pressure acts to drive the element opposite the direction. The co-operable features are configured such that a ratio, of the effective area over which the ground water pressure acts to the effective area over which pool water pressure acts, has a value of at least 0.9.

  • Patent number: 9845631
    Abstract: Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect drive-fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals.

  • Patent number: 9845643
    Abstract: A cable arrangement for feeding power and signals to downhole equipment, such as an electrically submersible pump (6), within an oil or gas well, comprising an upper suspension element (15), a lower connector (22), a docking station (11?) for the downhole equipment coupled to said connector (22), and a cable (8a), comprising lines for power and signal. The cable extends between, and is coupled to, the upper suspension element (15) and the lower connector (22). The docking station (11?) is adapted for attachment to the inner surface of a production tubing (5), that a narrow gap is formed between the production tubing (5) and the downhole equipment (6). The cable (8) is shaped to fit inside the gap by having a first dimension in the radial direction of the gap, which is smaller than the gap and a second dimension in the tangential direction of the gap, which is substantially larger than the first dimension.

  • Patent number: 9845646
    Abstract: A pipe handler trailer assists with the handling of very large and heavy pipes that are regularly raised to and lowered from an elevated surfaces. A height adjustment assembly sets the maximum height that a skidway will reach when a lift cylinder is fully extended and lift arms are thereby rotated. Located within lift arms are toothed racks. An adjustment block couples the skidway to lift arms through the racks and also supports locking blocks that have teeth complementary to the teeth on the racks. A lock will vary from firm contact with the inner wall of lift arms to having a gap there between. When the lock engages the inner wall of the lift arm this drives the complementary teeth into secure engagement with the rack teeth, which can then rigidly support heavy load without motion.

  • Patent number: 9845653
    Abstract: A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs.

  • Patent number: 9845656
    Abstract: A device and method to control the rate of radial expansion of a compressible sealing element on a packer over the longitudinal length of the sealing element. By varying the rate of compression of the element, the rate of radial expansion of the corresponding portions of the element may also be controlled. Additionally, the rate of radial expansion may also be controlled by controlling the direction and amount of radial expansion along the length of the sealing by reinforcing certain portions of the sealing element while decreasing the rigidity of the reinforcement for other portions.
