Abstract: A quick connector includes a female pipe having a flange in the outer peripheral part thereof, a male pipe having a retainer mounting part, and a retainer slidably mounted on the retainer mounting part of the male pipe to slide at a right angle to the axial direction of the male pipe, in which the female pipe and the male pipe are connected with each other by the retainer holding the flange of the female pipe, and the retainer is allowed to move from a temporarily fixed position to a completely pushed-in position on the retainer mounting part only when the female pipe and the male pipe are in a completely connected state, so that a worker can easily and reliably check whether the pipes are in an incompletely connected state or in a completely connected state by means of hand feeling only without relying on a visual check.

Abstract: The sawing machine according to the invention comprises a double portal structure (11) with two pairs of uprights (11.1), along which slides a respective ram (13). The rams (13) bear four support shafts (15), superposed in pairs and each supporting a coaxial roller, respectively a plurality of coaxial pulleys (18), mutually juxtaposed in packet fashion, having coplanar races according to respective vertical planes. A shaft (15) rotates integrally with the respective roller, or with the respective packet of pulleys (18). The other rollers, or packets of pulleys (18) are idle. On sets of four coplanar races is wound a corresponding wire or cutting tool (19) in closed loop, to execute the cut in a corresponding vertical plane of a block of material (B).

Abstract: The invention relates to a high-hardness palladium alloy for manufacturing semi-finished products to be used in goldsmith's art or jewels to be obtained by the lost wax casting method, which comprises, in the following concentrations, expressed in thousandths by weight (‰): palladium from 948 to 990‰; copper from 0.0 to 50‰; indium from 0.0 to 50‰; gallium from 1 to 48‰; aluminium from 0.8 to 49.5‰; ruthenium from 0.0 to 50‰; rhenium from 0.0 to 50‰; silicon from 0.1 to 1.2‰; platinum from 0.0 to 40‰; nickel from 0.0 to 50‰; iridium from 0.0 to 40‰. In the manufacturing process of the above alloy, the component elements of said alloy are placed in a crucible, respectively made of zirconia, boron nitride or other ceramic material, and are melted using the induction method and using a protective atmosphere, respectively of argon, nitrogen or other inert gas.

Abstract: A connection structure for a resin pipe, in which leakage of fluid from between a metal pipe and the resin pipe fitted on the metal pipe is prevented for a long time. In the connection structure, at least two diameter-expanded sections (10, 11) are formed with a spacing on an end region of a metal pipe (1), the spacing between the two diameter-expanded sections (10, 11) functioning as a circumferential groove (12) in which a seal ring (SR) is received, and a resin tube (2) is fitted up to a position beyond a far side diameter-expanded section (11) of the two diameter-expanded sections (10, 11). A back ring (BR) is received in the circumferential groove (12) together with the seal ring (SR). The diameter-expanded sections (10, 11) of the metal tube (1) are formed by bulging or spool shape-forming process.

Abstract: A method for concentration of fine particles dispersed in a dispersion into an ionic liquid comprising, adding an ionic liquid, especially an organic ionic liquid at ordinary temperature, e.g., a salt of 1-butyl-3-methylimidazolium with PF6? to a dilute dispersion of fine particles so as to concentrate the fine particles into the ionic liquid.

Abstract: A problem solved by this invention is to enable prevention of damage to a connector in a fluid transfer tube that is made by mounting a connector to an end of a tube, even when an outside air temperature falls below freezing point. The problem is solved as follows. In a fluid transfer tube that is made by mounting pipe joints to ends of a tube that has elasticity, tube connecting portions of the pipe joints and sections of the tube in the vicinity of the tube connecting portions are covered with heat radiation preventing covers to thereby delay freezing of a fluid inside the tube sections that are covered by the heat radiation preventing covers.

Abstract: The invention relates to unglycosylated folded C-terminal fragments of a multidomain serine protease of the complement cascade obtainable by expression in a bacterial host, wherein said serine protease is capable of binding a recognition molecule of the complement cascade, e.g. C1 or MBL. The invention also relates to methods and bacterial expression vectors for the preparation of said fragments, uses of said fragments for raising antibodies and screening substrates or inhibitors of said serine proteases and uses of the fragments in research and treatment of complement related disorders. The invention also relates to assay methods for assessing MASP-1 and MASP-2 levels in a sample of biological origin. The invention provides for research tools, assays and diagnostic kits useful in complement research and research and diagnosis of complement related disorders.

Abstract: In general, the invention is directed to systems and techniques for assessing a risk of ventricular tachyarrhythmia in a patient by measuring one or more biochemical markers that reflect the health of a patient. Typically, the patient submits a sample, such as a blood sample, which is tested for one or more biomarkers. Based upon the results of the tests, the patient's risk of ventricular tachyarrhythmia may be assessed. When the patient is found to be at risk, the patient may receive an implantable medical device or drug therapy to address the risk.
