摘要： A fluid coupling that attaches to a threaded component. The body portion of the fluid coupling has an end that defines a flow path along an axis and includes a first seal groove. An extension of the fluid coupling is mounted onto the end. The extension rotates about the axis and moves axially relative to the body portion. The extension includes a threaded tip for threadably coupling the threaded component. The extension also has a radially extending face adjacent the tip that includes a second seal groove. A first seal of the fluid coupling is positioned in the first seal groove and is adapted to provide a seal between the body portion and the extension. A second seal of the fluid coupling is positioned in the second seal groove and is adapted to provide a seal between the extension and the threaded component.

摘要： A check valve assembly is disclosed for use with a pool or spa plumbing system and includes first and second hub sections connected together by a nut member. An insert member carrying an elastomeric diaphragm is sandwiched between the first and second hub members to permit fluid flow in a first direction and prevent fluid flow in a second reverse direction. The assembly is designed such that the nut member may be moved longitudinally along one of the hub sections to expose and permit removal of the insert member in a direction transverse to the longitudinal axis of the hub sections. The nut member and insert are configured to cooperate with each other such that the insert may only be mounted in the assembly facing in a predetermined direction.

摘要： Method of making grooved, bell-ended thermoplastic pipe. In order to remove the core from undercuts, most of the molded article is cooled until substantially rigid while the bell-end is cooled more slowly. The article is ejected from the mold while the bell end is still soft enough to be deformed during ejection but recovers its shape after removal from the mold.

摘要： There is described a process and apparatus for treating oleaginous seed materials, such as soybean flakes with an extraction solvent, which includes an extraction zone, a desolventizing zone, and a miscella treating zone. In the extraction zone, the oleaginous seed material is subjected to concurrent contact with a carbohydrate-selective extraction solvent in a plurality of extraction vessels arranged in countercurrent fluid relationship therebetween with the expression of treated solids being effected after each extraction. The expressed solids from the last extracting vessel are passed to a desolventizing zone wherein residual solvent is vaporized by the respective indirect and direct contact with a heat transfer medium, such as steam, to produce a protein concentrate having a concentration (moisture free basis) of proteinaceous matter of at least about 70% by weight (6.25 times the total nitrogen content by the Kjeldahl method).The miscella is passed to a miscella treating zone which includes fractionating columns operating at different pressure levels in a multiple effect type of distillation system. The miscella is first introduced into a low pressure fractionating column and passed in indirect heat transfer relationship with the gaseous overhead from a second fractionating column to evaporate a portion of the extraction solvent. The bottoms from the low pressure fractionating column are then passed to the second fractionating column operating at a higher pressure and are passed in direct heat transfer relationship with steam and reboiled vapors to evaporate substantially all of the remaining portions of the extraction solvent with the liquid bottoms or whey being withdrawn for further processing.
