摘要： A backflow prevention device including an upstream shutoff valve configured to allow a user to control the water flow stream through the housing. The upstream shutoff valve includes an obstruction. The obstruction is configured to prevent water flow at a first position and allow water flow at a second position. The obstruction is also configured to rotate about an axis of rotation between the first position and the second position. The upstream shutoff valve also includes a seal. The seal is configured to sealingly engage a sealing surface in the housing at the first position. All points of engagement between the obstruction seal and the sealing surface are located downstream of the axis of rotation of the obstruction.

摘要： A check valve module. The check valve module includes an orifice, where the orifice is configured to allow the water flow stream through the check valve module. The check valve module also includes a clapper. The clapper is configured to allow the water flow stream through the orifice when open and prevent the water flow stream through the orifice when in a closed position by mating with the orifice. The check valve module further includes a fulcrum apparatus about which the clapper is allowed to rotate, a rotational constraint apparatus which directs the rotation of the clapper and a lateral constraint apparatus which directs the motion of the fulcrum toward and away from the orifice.

摘要： Spin-in and spin-out apparatus and methods are presented wherein an oilfield tubular spinner used in combination with a wrench detects the shouldering-up of tubulars during make-up and tubular thread disengagement during break-out. Sensors are employed to quantify measurables indicative of shouldering-up and thread disengagement, the measurables being used to shutdown spin-in and spin-out operations. Thresholds are employed to detect measurable values of interest. Timers are employed to monitor and control the spin-in and spin-out operations.

摘要： An implantable modular orthopedic prosthesis, preferably for hip, knee or shoulder arthroplasty, is disclosed which consists of three components. A first component has an elongated stem with a free end, configured to be situated within the intramedullary canal of a patient's bone, and an opposite end having an articulating portion such as a Morse-tapered member. A second component has another articulating portion which can also be a corresponding tapered member that is matingly engageable with the articulating portion of the first component. A third component has a body with a linearly-extruded channel through which the articulating portions are adjustably received, wherein at least one of the first and second components is radially-expandable to pressure lock against an internal surface of the channel in a selected position and arrest the first, second and third components together as the articulating portions are fully engaged with one another.

摘要： Clay compositions useful for modification of organic and aqueous fluids may be prepared from clays, silicon compounds, onium compounds or combinations thereof. An aqueous clay slurry may be acidified to form an acidic clay slurry. At least one silicon compound may be contacted with the aqueous clay slurry to form a silanated clay composition. In certain embodiments, a silanated clay composition may be contacted with an onium ion to form a silanated organoclay composition. In some embodiments, the silanated clay compositions may be incorporated into monomer and/or polymer systems to make composites with improved performance.

摘要： A control arm for use in a vehicle suspension. The control arm includes a first connection, the first connection configured to secure the control arm to a first external device and a second connection, the second connection configured to secure the control arm to a second external device. An external force expands or contracts the distance between the first connection and the second connection within predetermined limits. The control arm also includes a mechanical bias, where the mechanical bias returns the distance between the first connection and the second connection to a set free length when the external force is removed.
