A hose stop and associated assemblies and methods. The hose stop is configured for being mounted on a flexible hose through the deformation of the hose and subsequent reduction of the deformation.

A pipe joint made of synthetic resin includes: a joint body including a male screw portion on an outer circumferential portion; and a union nut including a female screw portion formed on an inner circumferential portion such that the female screw portion is tightened onto the male screw portion of the joint body. An outer circumferential surface of the joint body has a projection portion that is integrated therewith and projects radially outward. An inner circumferential surface of the union nut has a convex or concave engagement portion that is integrated therewith and engages with the projection portion when the union nut is tightened up to an appropriate position.

A flow management system includes an adjustable compactor configured for attachment to a wall surface of a conduit and being adjustable between an extended configuration and a reference configuration, an electric actuator in fluid communication with the adjustable compactor, and a control module. The control module is configured to control the electric actuator to flow a current to the adjustable compactor to generate an electric field that causes extension of the adjustable compactor for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to remove the electric field at the adjustable compactor to cause the adjustable compactor to return to the reference configuration for opening the channel to a fluid flow within the conduit.

Method is for operating fluid-processing plant configured to generate and store pressurized fluid, and spaced apart from body of water. Method includes: (A) positioning variable-buoyancy assembly in body of water in such way that buoyancy force urges variable-buoyancy assembly to move toward surface of body of water; (B) positionally anchoring, at least in part, non-collapsible fluid-line assembly underground in such way that non-collapsible fluid-line assembly extends, at least in part, into body of water; (C) fluidly connecting, via non-collapsible fluid-line assembly, fluid-processing plant and variable-buoyancy assembly together in such way that non-collapsible fluid-line assembly conveys pressurized fluid between fluid-processing plant and variable-buoyancy assembly; and (D) transmitting an anchoring force, via non-collapsible fluid-line assembly, from ground to variable-buoyancy assembly in such way that anchoring force substantially counteracts buoyancy force acting on non-collapsible fluid-line assembly, and anchoring force substantially urges variable-buoyancy assembly to remain below surface of body of water.

An electrically grounded wear resistant liner is described that inserts into a conventional frac sand delivery conduit. The liner allows for conveyance of highly abrasive materials through the liner and conduit while electrically grounding potential static build up from within the liner. Sand, cement and other abrasive slurries may be conveyed through the liner. The wear resistant liner extends the amount of time that the conduit may be used to convey materials without downtime for replacement and repairs. The liner further provides a tri layer construction that includes a middle layer having a color notably different than the outer and inner layers, allowing a user in the fields to quickly determine that the conduit should be replaced.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

Provided is a substrate processing apparatus that includes: a rotary joint including a rotary unit that rotates together with the rotation of the head unit, a fixing unit that is provided around the rotary unit, and a sealing unit that seals a gap between the rotary unit and the fixing unit; and an outlet pipe through which the quenching water is discharged. A first flow passage through which a gas passes and a second flow passage through which the quenching water passes are formed in the rotary joint, and the second flow passage is isolated from the first flow passage by the sealing unit. One end of the outlet pipe communicates with an outlet port of the second flow passage of the rotary joint, and the other end of the outlet pipe is opened to atmosphere at a position lower than the outlet port of the second flow passage.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.
