摘要:
A fuel injector comprises a body having a longitudinal axis, a length-changing actuator that has first and second ends, a closure member coupled to the first end of the length-changing actuator, and a compensator assembly coupled the second end of the actuator. The length-changing actuator includes first and second ends. The closure member is movable between a first configuration permitting fuel injection and a second configuration preventing fuel injection. And the compensator assembly axially positions the actuator with respect to the body in response to temperature variation. The compensator assembly utilizes a configuration of at least one spring disposed between two pistons so as to reduce the use of elastomer seals to thereby reduce a slip stick effect. Also, a method of compensating for thermal expansion or contraction of the fuel injector comprises providing fuel from a fuel supply to the fuel injector; and adjusting the actuator with respect to the body in response to temperature variation.
摘要:
Disclosed is a device for continuing detecting blood parameters. The device includes a catheter adapted to be introduced into the artery of a patient. A sensor is arranged in the catheter. A tube us adapted to be coupled to a vein of a patient and is also connected to the first catheter. A device controllably maintains blood flow across the sensor, the device being controlled such that initially the flow of blood to the first catheter via the tube is prevented so long as the detective blood parameters indicated a sufficient amount of fresh arterial blood is flowing around the sensor. In the event that a detective blood parameters indicate that an insufficient amount of blood flows around the sensor, then blood flow through the first catheter to the vein of the patient via the tube is then established.

A peptide consisting of 7-17 amino acids and including the adjacent hexamer TX1EX2X3E, where X1, X2 and X3 can be any natural or non natural amino acid, wherein the peptide does not exhibit TNF-receptor-binding activity and is cyclic, for the treatment or prevention of vascular complications in diabetes patients.
摘要:
The invention relates to a method, particularly suitable for the extraction and enrichment of a volatile component from a liquid, solid or gaseous sample for subsequent introduction into an analytical device, for example, a gas chromatograph. The sample is flushed through a packing of extraction material for extraction of the analytes of interest. A suitable device comprises a syringe with a hollow needle. A chamber is provided between the needle and syringe, in which the extraction material is arranged.

摘要:
A hydrocarbon reformer system for a fuel cell system comprising a feedstream delivery unit (FDU) and a hydrocarbon catalytic reformer (CR). The reformer includes a catalyst disposed in a housing. Ahead of the catalyst is the FDU including a mixing element in the shape of a cone for receiving any or all of air, hydrocarbon fuel, anode tailgas, and steam. The cone has tangential entry slots for the reactants. Addition enclosures combine reactants prior to entry into the cone through the slots. Fuel is metered into the reactants in the enclosures. A manifold having a tangential entry for receiving reactants surrounds the cone. Swirl flow within the cone creates an intense low-pressure zone within the cone, causing turbulence and mixing of the reactants. Homogenized reactants leave the cone in a sheet flow nearly uniform in temperature that enters the catalyst and allows uniform catalysis over the entire catalyst surface.
