An oral irrigator handle has a handle housing with a swivel assembly for connection to a hose further connected to a fluid source. A tip for directing a focused stream of fluid is releasably connected to a first end of the handle. The swivel assembly is received within the housing and fluidly coupled to tip. The hose is connected to the swivel assembly and fluidly coupled to the tip via the swivel assembly. The swivel assembly prevents translation of rotational movement of the handle or the hose to the other.

A hydraulic hose fitting comprises a hydraulic hose engaging portion and a hydraulic port engaging portion. The hydraulic hose engaging portion includes a body having an axial bore extending therethrough and a stem press-fit into the axial bore. The hydraulic port engaging portion is coupled to the hydraulic hose engaging portion. The hydraulic port engaging portion may be a swivel nut.

A fluid swivel that includes a stationary annular structure defining upper and lower annular seal recesses, and a rotatable outer housing operatively connected to the stationary annular structure, the outer housing defining an annular passage that has upper and lower surfaces. Upper and lower seals are positioned between the stationary annular structure and the rotatable outer housing and disposed in the upper and lower seal recesses. An inner housing bore is disposed in the stationary annular structure and arranged to provide fluid of pressure P to the annular passage, the fluid exerting a first force (Fv.sub.1) longitudinally inwardly on the outer surface of the outer housing, and a second force (Fv.sub.2) longitudinally outwardly on the upper and lower surfaces of the annular passage, the second force (Fv.sub.2) having a greater magnitude than the first force (Fv.sub.1) so the outer housing deflects outwardly, pushing the upper and lower seals into the upper and lower seal recesses.

An anhydrous ammonia nurse tank coupling had a locking collar for securing a flow nozzle to a nurse tank fitting. A nipple is threadingly secured to the fitting and has a hexagonal-shaped section. A nozzle coupling extends about said flow nozzle for threadingly securing to the flow nozzle to the nipple. The nozzle coupling and the nipple have acme threads which are secured together, with a seal element extending between the nipple and the flow nozzle. A locking collar slidably disposed on said nozzle coupling, for moving from a retracted position disposed aside of the hexagonal-shaped section of the nipple to an extended position disposed adjacent to the hexagonal-shaped section and non-rotatably securing the locking collar to the nipple. The locking collar is non-rotatably secured to the nozzle coupling in the extended position, and non-rotatably secures the nozzle coupling to the nipple when in the extended position.

A method of providing a drain pipe passageway through a concrete slab wherein a plastic pipe of predetermined diameter, which is greater than the underlying drain pipe, is positioned in an upright manner within a location of a concrete slab to be poured. Concrete is poured around the pipe to a desired level leaving a portion of the pipe exposed above this level, and the concrete is permitted to solidify. Thereafter the exposed portion of the pipe is cut off leaving an upper opening of the pipe flush with the upper surface of the concrete slab. The upper opening of the pipe is closed off with a plastic cap and a passageway of predetermined diameter, which is smaller than the pipe diameter, is drilled through the cap at a newly calculated position of alignment, and a plastic pipe having an outside diameter which will mate with this smaller diameter of the passageway is inserted through the cap passageway and cemented in position.

The present device provides a composite rotary union assembly which overcomes the disadvantages of prior art rotary union assemblies. The composite rotary union assembly of the present invention provides for supplying water or gas to a rotatable reel assembly, it also provides metal inserts for high wear areas of the rotary union assembly, including the threads, for longer useful life of the assembly while providing a resin structure for supporting and placing the metal portions.

A fluid conveyance system connector includes a body and a tube positioned within the body through which a conveyed fluid flows. A moveable adapter is received in a first space between the body and the tube. The moveable adapter sealingly cooperates with the body and tube to define outer and inner variable volume chambers. The inner chamber communicates with one of an external environment or the conveyed fluid through a first port and the outer chamber communicates with the other of the conveyed fluid or the external environment through a second port such that the pressure in the inner chamber is the pressure exhibited by the external environment or the conveyed fluid and the pressure in the outer chamber is the pressure of the other of the conveyed fluid or the external environment. A differential pressure comprising a difference between the pressure of the conveyed fluid and the pressure exhibited by the external environment applies an inwardly or outwardly directed force to the moveable adapter.

The present invention describes a tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop includes a bend with a bend radius that is from two to four times the diameter of the scoop. The scoop defines a scoop face that is parallel to an axis of the tubular of the scoop. The scoop is mounted with a threaded connection that seals around the tubular. An additional seal comprises a compression nut that allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut.

A sealed joint assembly for transmitting high temperature and high pressure fluid between adjoining ducts in, for example, an aircraft bleed air system, includes a gimbal ring and two annular clevises. Each clevis includes a pair of axially-extending lobes that each includes a bore hole extending therethrough. The bore holes of the clevis lobes may each align with a respective bore hole formed within the gimbal ring, through which a pin may be inserted to couple the clevises to the gimbal ring. The clevises and gimbal ring may be formed using additive manufacturing. The gimbal ring may include a strut or truss network, and may be comprised of an inner gimbal ring and an outer gimbal ring.
