A nut includes an internal thread and at least two parts, each of the parts having a section of the internal thread which can be pushed onto an external thread in the radial direction. The parts may have connecting elements which interact and permit a relative displacement of the parts in a direction running radially to the axis of the internal thread into a position of use. The connecting elements may have guide surfaces which are inclined at an angle to the plane running radially to the axis of the internal thread and guide the parts in a rotational movement about an axis of rotation running transversely to the axis. A part may have a locking arm with a guide surface only on one side which produces the rotational movement during the displacement of the parts and bears against a complementary guide surface of the other part.

A speckle composition for use in particulate laundry detergent compositions comprising a porous granular carrier, and at least 0.01 wt % photobleach, preferably at least 0.05 wt %, more preferably at least 0.1 wt %, based on the active ingredient the composition being layered with a finely divided high carrying capacity particulate material and / or a water-soluble material. The most preferred photobleach is a blend of Zn and Al sulphonated phthalocyanine.

Provided is an emission treatment system and method for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The emission treatment system has an oxidation catalyst upstream of a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia. Also provided is a method for disposing an SCR catalyst composition on a wall flow monolith that provides adequate catalyst loading, but does not result in unsuitable back pressures in the exhaust.

An implantable medical device includes a porous metal foam or foam-like structure having pores defined by metal struts or webs wherein the porous structure has directionally controlled pore characteristics. The pore characteristics controlled include one or more of the metal structure porosity, pore size, pore shape, pore size distribution and strut thickness. The pore characteristics may vary in one or more directions throughout the structure. Preferably the pore characteristics are controlled to match the porous metal structure to various mechanical and biological requirements of different regions of the structure in order to optimize aspects of the implants performance and may vary not only over the surface of the porous structure but through the depth of the porous structure. The thickness of the porous metal structure may also be modified to establish a thickness profile that optimizes mechanical and biological requirements of the implants performance. Acetabular cup embodiments of the invention are described. Various methods of manufacturing implants having directionally controlled pore characteristics are described.

A mode selector mechanism is provided for a rotary power tool for selecting between an impact mode and a drill mode. The power tool includes a housing, a motor oriented in the housing, an input shaft and an output shaft both rotationally mounted in the housing. An impact mechanism connects the input shaft to the output shaft for imparting a rotary impact to the output shaft when the torque load exceeds a predetermined torque capacity of the impact mechanism. A stopping member is shiftable by a user between a first orientation that permits the impact mechanism to operate in the impact mode and a second orientation that prevents a coupler of the impact mechanism from retracting, thus maintaining the connection of the input shaft and the output shaft in the drill mode.

This invention relates to a thermally conductive moldable polymer blend comprising a thermoplastic polymer having a tensile at yield of at least 10,000 psi; at least 60% by weight of a mixture of boron nitride powders having an average particle size of at least 50 microns; and a coupling agent. The composition displays a thermal conductivity of at least about 15 W / m DEG K and it is capable of being molded using high speed molding techniques such as injection molding.

Sensors and detection systems suitable for measuring analytes, such as biomolecule, organic and inorganic species, including environmentally and medically relevant volatiles and gases, such as NO, NO2, CO2, NH3, H2, CO and the like, are provided. Certain embodiments of nanostructured sensor systems are configured for measurement of medically important gases in breath. Applications include the measurement of endogenous nitric oxide (NO) in breath, such as for the monitoring or diagnosis of asthma and other pulmonary conditions.

The present invention provides minimally invasive imaging probe / medical device having a frictional element integrated therewith for reducing non-uniform rotational distortion near the distal end of a medical device, such as an imaging probe which undergoes rotational movement during scanning of surrounding tissue in bodily lumens and cavities.

The invention discloses a super-power five-cylinder plunger pump. The super-power five-cylinder plunger pump comprises a power end assembly, a fluid-power end assembly and a reduction box assembly; the power end assembly adopting a sectional type structure design includes a crankshaft box body, a crosshead box body and a space-stop rack, one end of the crosshead box body is connected with the crankshaft box body, and the other end of the crosshead box body is connected with the space-stop rack; the fluid-power end assembly is arranged at one end of the space-stop rack, and the fluid-power endassembly passes through the space-stop rack and the crosshead box body in sequence and is connected with the crankshaft box body through bolts; and the reduction box assembly is connected with the crankshaft box body, a crankshaft in the crankshaft box body is forging alloy steel, the crankshaft includes six shaft necks and five crank threw, each crank throw is arranged between two adjacent shaftnecks, and the distance between the crank threw and the rotating center of the crankshaft is 110mm to 160 mm. The super-power five-cylinder plunger pump has the beneficial effects that the rated inputpower of the super-power five-cylinder plunger pump is 5000 hp, so that the problem that high-power motors cannot be matched with the plunger pumps of corresponding specifications in electric drive fracturing is solved, and the contradictions that the conditions in oil and gas well fields are limited and the matching of fracturing equipment is much is further solved at the same time.
