Abstract: A system and method is described for importing data from a source computer system, manipulating and transforming of that data, and exporting the data to a target computer system under control of a script processor using stored metadata definitions. Metadata is used to describe the properties of the data being manipulated. The system includes a means for manipulating the metadata definitions. The metadata definitions are created to import data into the system, export data from the system, create views of the external data, store generic format data within the system, manipulate generic format data within the system and to control data flow through the system. Data is imported into the system using an import data definition to map the external data into an import data bag. Data imported into an import data bag becomes independent of the original data source. Data is manipulated within the system using script control commands and data is transformed within the system using rule sets that act upon data bags.

Abstract: The pinion (10) on the pin shaft (11) and/or the pinion shaft bearings to either side of the pinion and/or the pinion shaft pillow blocks (12, 13) are supported by elastically deformable components (15, 16, 22, 23) so as to automatically adapt radially in an elastically compliant manner to variations in the meshing of the pinion with the rim gear on the driven rotary drum of a tube mill or the like.

Abstract: This invention relates to an internal combustion engine with intake and exhaust valves (6, 7) and one nozzle mount (4) per cylinder (2) for an injection nozzle (5) injecting fuel into a combustion chamber, the nozzle mount being connected to a fuel supply line (14) and a return oil line (19), the nozzle mount (1) being screwed into a first recess (13) in the cylinder head (1), and the cylinder head (1) exhibiting a second recess (17) approximately normal to an engine longitudinal plane (16) containing the cylinder axis (3), which second recess, extending from a first cylinder head longitudinal side wall (15a), intersects the first recess (13) approximately radially. In order to make possible a reliable fuel supply to the nozzle mount (4) with minimal space requirement and short fuel supply lines (14), the second recess (17) continues up to the second cylinder head longitudinal side wall (15b) lying opposite the first cylinder head longitudinal side wall (15a) and forms in this region the return oil drain.

Abstract: A solvent composition and corresponding method for extracting cesium (Cs) from aqueous neutral and alkaline solutions containing Cs and perhaps other competing metal ions is described. The method entails contacting an aqueous Cs-containing solution with a solvent consisting of a specific class of lipophilic calix[4]arene-crown ether extractants dissolved in a hydrocarbon-based diluent containing a specific class of alkyl-aromatic ether alcohols as modifiers. The cesium values are subsequently recovered from the extractant, and the solvent subsequently recycled, by contacting the Cs-containing organic solution with an aqueous stripping solution. This combined extraction and stripping method is especially useful as a process for removal of the radionuclide cesium-137 from highly alkaline waste solutions which are also very concentrated in sodium and potassium.

Abstract: A cutting tool having a body that is cylindrical in shape having a shank at one end and a cutting end opposite thereof. The cutting end has an even number of flutes thereon with every other flute being a cutting flute, such as a knuckle flute including a radial knuckle flute and a flat crested knuckle flute, or a diamond cut flute that cuts material. Every other flute therebetween the cutting flutes are wiper flutes that wipe or clean the cut material. The wiper flutes have a larger diameter than the cutting flutes thereby enabling the wiper flutes to remove any unnecessary debris and finish the material in a single step.

Abstract: An apparatus for feeding articles, comprising: a surface; a plurality of conveyor belts spanning the surface; a motor driving the conveyor belts for transporting the articles along the surface; a barrier bar positioned above the surface for preventing further transport of the articles along the surface; and an actuator connected to at least one of the conveyor belts. The actuator raises at least a first portion of the conveyor belt a distance above the surface and lowers the conveyor belt back to the surface. Raising the actuator propels one of the articles past the block. The article feeding apparatus can be one component of a larger article handling system.

Abstract: A compact reversing flow catalytic converter for reducing noxious substances in exhaust gases produced by internal combustion engines is described. The catalytic converter includes a valve unit which reversibly directs exhaust gases through a container filled with catalytic material. The container defines a U-shaped gas passage which communicates with two ports at a top of the container. The valve unit is mounted to the top of the container and includes an intake and an exhaust cavity. The valve unit includes a valve disk having two openings therethrough and rotates around a perpendicular central axis between a first and second position. In each position, each opening communicates only with one of the cavities and one of the ports. In the first position, the exhaust gases enter the exhaust cavity from an exhaust pipe and pass through one of the openings into the gas passage where they contact the catalytic material as they travel through the U-shaped gas passage and enter the exhaust cavity.

Abstract: A conversion system for converting a spark ignition engine to operate on gaseous fuel is disclosed. The conversion system includes an electronic controller which operates on several novel principles to provide superior performance/responsiveness and to reduce exhaust emissions. The controller in accordance with the invention assumes complete control of spark ignition timing when gaseous fuel mode is enabled and generates independent spark ignition signals tailored to the gaseous fuel. The controller also generates an independent pulse width modulated gaseous fuel injection signal that controls a high performance electronic solenoid injector valve to supply gaseous fuel to the engine. Variable injector speed is used to compensate for the dynamic range of the engine. A novel dual array block learn scheme is used to provide efficient fuel control in engines equipped with closed-loop monitoring systems and exhaust gas recirculation.
