Abstract: An apparatus and method for expanding a lower string of casing into frictional contact with an upper string of casing, and thereby hanging the lower string of casing onto the upper string of casing is provided. The apparatus substantially defines a lower string of casing having a scribe placed into the top end thereof. The lower string of casing is run into the wellbore, and positioned so that the top end overlaps with the bottom end of an upper string of casing already cemented into the wellbore. The top end of the lower casing string is expanded below the depth of the scribe into frictional contact with the upper string of casing. At the same time, or shortly thereafter, the top end of the upper string of casing is expanded. As the portion of the lower casing string having the scribe is expanded, the casing severs into upper and lower portions.

Abstract: Wind power installation technology has seen dramatic developments in the last 20 years. In the meantime there are installations of the order of magnitude of up to 5 MW and future development leads to an expectation of installations with an even greater nominal power. The present application does not preferably concern such megawatt installations but rather small installations, in particular a small wind power installation of between about 50 and 150 kW nominal power, which can be set up practically at any location in the world as independently as possible of intensive machine support. The object of the present invention is to simplify the erection of a wind power installation. A wind power installation comprising a plurality of installation parts such as rotor, generator, machine casing and pylon, wherein the installation parts are disposed in a container during transport to the building site of the wind power installation and are assembled to form a wind power installation at the location of construction of the wind power installation, wherein the container is such that it accommodates the pylon of the wind power installation and forms the foundation of the wind power installation.

Abstract: A splitter divides an air/product mixture flow, delivered thereto in an air- powered distribution line, between a primary and a secondary distribution channel, which may be flow--coupled to a product hopper or a hose flow-coupled to another product hopper or another splitter. The air/product mixture enters the inlet of the splitter along an angled downward flow path and exits a primary outlet, flow-coupled to the primary distribution channel, along a vertical downward flow path. Air/product flow is exhausted by a secondary outlet, which is flow--coupled to the secondary distribution channel, at an angled upward flow path. The velocity flow vector along which the air/product mixture is exhausted from the secondary outlet is at an acute angle relative to the velocity flow vector along which the air/product mixture is received by the inlet of the splitter.

Abstract: Adherence to exhaust gas limit values for diesel vehicles requires removal of nitrogen oxides from exhaust gas. 'Active SCR process' is a preferred method. Nitrogen oxide conversions achieved by this process are particularly high when an optimal NO2/NOX ratio is set upstream of the SCR catalyst. The invention proposes a process which solves the problem of supplying NO2 in accordance with requirements by temperature control of the precatalyst which is decoupled from the operating state of the engine. In an associated apparatus, a precatalyst which contains at least one oxidation component and whose temperature can be controlled independently of the operating state of the engine, and an active SCR stage comprising an SCR catalyst with upstream metering facility for a reducing agent from an external source are arranged in series. A particle filter can be arranged between precatalyst and metering facility. The precatalyst can contain a nitrogen oxide storage material.

IPC: A61C1/07
Filed: 2009-03-18
Granted: 2016-08-02
Abstract: The present invention describes an ultrasonic dental insert capable of enhanced operating efficiency. A first transducer generates ultrasonic vibrations. A connecting body has a proximal end and a distal end having a tip attached thereto. The proximal end is attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end. The ultrasonic dental insert may be inserted into a handpiece for providing electromagnetic energy to the first transducer to generate the ultrasonic vibrations. The ultrasonic insert, when seated in the handpiece, is substantially decoupled, on a rotary axis, from the handpiece. A rotary force need only be applied to the insert to rotate it in the handpiece. At least one light source substantially proximate or distal to the tip may also be provided.

Abstract: A filter vial and piston are provided where the vial has a cylindrical wall with a closed bottom and open top and with the hollow, tubular piston (10) therein. The piston has a distal end covered by a cup (30) having a proximal cup seal extending outward to engage the walls of the vial to form a fluid tight seal with the vial during use. The distal end of the piston has a pist flange extending outwardly and located adjacent a recess in the piston so th cup forms a snap fit over the piston flange and extends into the recess. The piston flange causes the cup to bulge sufficiently outward to form a fluid tight seal with the vial during use. A filter (16) is placed in the bottom o the cup and abuts an inwardly extending lip on the cup. The filter is held against the lip by a piston support at the distal end of the piston. A cup support at a distal end of the cup also helps support the filter.
