    摘要： A grey water treatment system includes a first tank configured to receive grey water via a grey water supply conduit and that comprises an overflow, a second tank configured to store grey water, and at least one transfer conduit configured to at least transfer grey water between the first tank and the second tank. A control is configured to maintain a water level in said first tank sufficiently close to the overflow to allow floating contaminants to pass over the overflow. A method of treating grey water includes: receiving grey water in a first tank of a grey water treatment system; transferring grey water via at least one transfer conduit between the first tank and a second tank of said treatment system; and controlling a water level in said first tank sufficiently close to an overflow of said first tank to allow floating contaminants to pass over the overflow.

    摘要： A combination includes a plurality of segments attached to one another end to end around a central space. A channel is disposed between the sides of the segments. A sealing ring is positioned in the channels. A tube has a first end disposed within the central space. A first protrusion extends radially outwardly from the tube and limits the extent to which the tube can extend into the central space. The combination is configured such that an end of a pipe element may be axially inserted into the central space and fasteners can be tightened to draw the segments toward one another.

    摘要： Methods and systems for retaining bonnets on blowout preventers. In one embodiment, a blowout preventer includes a hollow body, a ram disposed in a ram cavity of the hollow body, and a bonnet coupled to the hollow body. The bonnet is fastened to the hollow body with threaded fasteners, which include a threaded shaft and a threaded nut. The shaft and the nut include mating interrupted threads with threaded portions and longitudinal unthreaded portions that can be rotationally aligned so that threaded portions of each of the shaft and the nut are aligned with unthreaded portions of the other of the shaft and the nut to allow the threaded shaft to be received within the threaded nut and the threaded nut to then be rotated with respect to the threaded shaft to cause the threaded portions of the threaded nut to engage the threaded portions of the threaded shaft.

    摘要： A gasket and flange connection structure for a plumbing instrument including a substantially annular core (30) coated with a coating part (31) and formed with annular seal surfaces (32) on both surfaces. These annular seal surfaces (32) are provided so as to be capable of making sealed contact with any of flange surfaces (20, 21, and 22) of a flat seat shape flange, a full-flat seat shape flange, and a grooved-shape flange for allowing shared use. Configured on outer peripheral sides of the annular seal surfaces (32) are extended mounting parts (33) having a plurality of different diameters in accordance with the outer diameters of the various flange surfaces.

    摘要： A pipe coupling device includes: a joint body into which a joining pipe is inserted; a C-ring-shaped retaining ring that includes a flange part protruding from an outer peripheral surface thereof fixed onto an outer peripheral surface of the joining pipe; and a pressing plate having a recessed part for housing the flange part. The retaining ring further includes a second flange part protruding from the outer peripheral surface thereof. The pressing plate further includes a pair of through-holes through which the coupling members penetrate, and a second recessed part for housing the second flange part. The second flange parts are provided with a circumferential center portion of the ring body between them, and the pressing plates are provided with the circumferential center portion between them. The recessed part is located between the through-holes, and the second recessed part is located outward of the through-holes in the circumferential direction.
