A valve having a trim comprising a plurality of a vortex flowpaths, each flowpath comprising a central vortex chamber and having three tangential inlet passages is provided. As the fluid flows through the inlet passages and enters the vortex chamber the flows start to turn and impinge upon one another, i.e., the flow entering via inlet passage will impinge upon the flow entering via inlet, the flow entering inlet will impinge on the flow entering inlet and the flow entering inlet will impinge on the flow entering inlet. As the flow entering vortex chamber impinges on another fluid flow as opposed to a wall of the flowpath the vortex can be used to create a flowpath with reduced erosion. The flow from the inlets combine in a radial flow within the vortex chamber and exit via the outlet which is substantially axial to the vortex chamber.

A connector includes a main conduit and a gas conduit. The main conduit includes an inlet portion and an outlet portion that form a passage for supply of a first gas in a forward direction. The inlet portion is adapted to receive a supply of the first gas and deliver the first gas to the outlet portion. The gas conduit has a first end and a second end that form a second passage for supply of a second gas. The first end of the gas conduit is adapted to connect to a second gas supply, and the second end is adjacent the outlet portion of the main conduit and delivers the second gas into the main conduit such that the second gas is directed to flow in a forward direction.

A system for validating a coin has a passageway through which the coin passes, in use; an oscillator having a component positioned relative to the passageway for the frequency and amplitude of oscillation of the oscillator to be varied, in use, by passage of the coin along the passageway; a period (or frequency) determining unit for determining the period (or frequency) of an oscillating signal provided by the oscillator when influenced by the coin and for supplying a determined period (or frequency) value; an amplitude determining unit for determining the amplitude of the oscillating signal provided by the oscillator when influenced by the coin and for supplying a determined amplitude value; and an assessing unit for assessing if the determined period (or frequency) and amplitude values lie in a predetermined window of period (or frequency) and amplitude values.

The present invention relates to a newly identified receptor belonging to the superfamily of G-protein-coupled receptors. The invention also relates to polynucleotides encoding the receptor. The invention further relates to methods using the receptor polypeptides and polynucleotides as a target for diagnosis and treatment in receptor-mediated disorders. The invention further relates to drug-screening methods using the receptor polypeptides and polynucleotides to identify agonists and antagonists for diagnosis and treatment. The invention further encompasses agonists and antagonists based on the receptor polypeptides and polynucleotides. The invention further relates to procedures for producing the receptor polypeptides and polynucleotides.

The invention provides apparatus having a sensor system for providing sensor information for a monitoring, control or other operating function of the apparatus. The sensor system comprises: a transducer (16) adapted to be responsive to a predetermined environmental characteristic of the apparatus for providing an electrical output, and means (18) adjacent to the transducer to accentuate the said characteristic. At least one sensor (20) is arranged to be operated by power derived from the electrical output for generating a detection signal, and means (38, 40) arranged to be operated by power derived from the electrical output and responsive to the detection signal are also provided for communicating sensor information to a processing unit remote from the sensor system and associated with the said function.

A multi-cartridge powered dispenser includes a frame having base and top cartridge supports, wheels and a handle. A piston/cylinder is mounted on the frame and at least three cartridges are clamped between the support plates. Each cartridge has a shuttle at the lower end and a discharge opening at the upper end. The piston/cylinder assembly has push rods extending through the base support to move the shuttles in the cartridges. A pressurized fluid supply conduit is connected to the piston/cylinder, and a valve in the fluid supply conduit controls the flow. Discharge cannulae communicate with the outlets the cartridges. Discharge conduits extend between the cannulae and a handpiece for applying the contents of the cartridges to a work surface. The application handpiece can be a sprayer, a roller applicator, or a pour/extrude applicator.
摘要:
Controlled dispense of a flowable reagent in a diagnostic system is characterized by placing in the diagnostic system at least one cartridge containing a reservoir of reagent and carrying an identifier device that has information pertinent to the reagent in the reservoir. The diagnostic system automatically reads the information contained in the identifier device and uses the information to control the diagnostic system in dispensing the reagent. The information contained in the identifier device may consist of one or more of an identification of the reagent in the reservoir; the expiration date of the reagent the active shelf life of the reagent; the volume of the reagent in the reservoir; an identification of the origin of the reagent; and the maximum storage temperature of the reagent.
摘要:
A tap for a urine drainage system, having a body, a lever and a barrel with a through bore which is mounted in the body for rotation between a position for through flow of liquid and a position which obturates fluid flow. The lever is mounted directly on the body for reversible rotation therearound, the arrangement being such that, on rotation of the lever, the barrel is movable between the two positions.
