A jet pipe assembly containing at least one joint provided with a seal assembly to isolate, substantially, the fluid flowing in the pipe from the fluid external to the pipe. The dynamic member of the seal assembly is provided with both radial and cylindrical sealing surfaces.

A fluid controller, wherein the recessed port (25) of a body (22) is formed of larger diameter part (25a) near an opening and a small diameter part (25c) continued to the lower part of the large diameter part (25a) through a step part (25b). A flow passage forming disk (26) is fitted to the recessed portion (25). The fluid passage forming disk (26) comprises a large diameter cylindrical part (31) fitted to the large diameter part (25a) in the recessed portion, a connection part (32) supported by...

A portable fluid heating tool capable of heating a flow of water under mains pressure to about 107 degrees Celsius and has a connection to a water supply via a hose. Water flows through an electrical heater within the tool, then to a thermally controlled pressure regulating valve (80) and then to the outlet nozzle. This valve (80) has a moveable member such as a diaphragm (83) sealing off a pressure chamber (88). Movement of the diaphragm (83) causes a valve (85) to open or at least partly close...

Fluid control apparatus and method of controlling fluid flow. The fluid control apparatus comprises an elongate tube having a first flow opening at an end of the tube and at least one second flow opening along the length of the tube, and a sleeve arranged to slide along said tube during fluid-flow conditions. A gap is present between the tube and the sleeve to allow some fluid to pass through the gap to displace the sleeve from the tube and to allow some flow even when in a fully closed conditio...

An ophthalmic fluid containing at least one triglyceride, diglyceride, or monoglyceride which is chemically similar or compatible with compounds found naturally in the lipid layer of the tear film of an ocular substrate. Preferably the glycerides are derived from a fatty acid containing at least one unsaturated bond in a cis-configuration in the fatty acid residue. The ophthalmic fluid is arranged in use to provide a protective film across a tear film of an ocular substrate. Furthermore, the oph...

The invention discloses a method of predicting the fluid level at a predetermined location in a fluid flow network (10) having at least one regulator (16, 18) to control the flow of fluid along fluid flow network (10). The method includes the steps of collecting data based on timed measurements of fluid levels upstream (24, 28) of at least one regulator (16, 18), fluid levels downstream (26, 29) of at least one regulator (16, 18) and the opening position (30, 32) of at least one regulator (16, 1...

A fluid machine for a waste heat collecting system for an internal combustion engine has an object to make most use of the collected waste heat and an operation of a compressor, an alternator or the like by a rotational driving force from an expansion device function well even during an engine running is stopped. The fluid machine according to the present invention has a pulley connected to the engine, an expansion device for generating a rotational driving force from the collected waste heat, a...

An apparatus for separating a first fluid from a mixture of fluids in a container, the first fluid being substantially immiscible with respect to one or more other fluids in the mixture comprises an endless strip of material having an affinity for the first fluid, a pair of members for advancing successive portions of the strip into and out of contact with the first fluid and a means for maintaining the successive portions of the strip in contact with the first fluid as the successive portions o...

A fluid tank fluid is provided which includes a bubble removing device provided therein to remove bubbles from the fluid. The bubble removing device includes a cyclone chamber for generating a swirling current in the fluid flowing therethrough to separate bubbles from the fluid. At least one outflow port is provided through which the fluid from which the bubbles have been separated flows from the cyclone chamber. And an exhaust port is provided through which the bubbles separated from the fluid ...

An apparatus for measuring the viscosity and temperature of a fluid, for example an engine oil, comprises a transducer, which is arranged to vibrate when provided with a drive signal to produce an ultrasonic shear wave; an impedance matching layer that is inserted into the fluid and which couples at least a portion of the ultrasonic waves produced by the transducer into the fluid and from which at least a portion of the wave is reflected back to the transducer; a detector which is adapted to det...
