Abstract: A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction.

Abstract: A method for producing compacts containing iron oxide from undersized oxidic iron carriers may include producing a mixture which comprises undersized oxidic iron carriers, bentonite as a binder and water, pressing the mixture and hardening the green compacts obtained by the pressing, as well as to the compacts produced by the method and to the use of the compacts as lump iron carriers. The mixture may be subjected to a kneading process lasting at least 3 minutes and up to 30 minutes, prior to the pressing. The compacts may thus be produced without a maturing process.

Abstract: A vane cell pump having an over vane pump associated with a first consumer and an under vane pump including an under vane pressure area and an under vane suction area which is connected to the over vane pump. The under vane pressure area is separated from the under vane suction area and is associated with a second consumer.

Abstract: The present invention relates to systems and methods for the arrangement of droplets in pre-determined locations. Many applications require the collection of time- resolved data. Examples include the screening of cells based on their growth characteristics or the observation of enzymatic reactions. The present invention provides a tool and related techniques which addresses this need, and which can be used in many other situations. The invention provides, in one aspect, a tool that allows for stable storage and indexing of individual droplets. The invention can interface not only with microfluidic/microscale equipment, but with macroscopic equipment to allow for the easy injection of liquids and extraction of sample droplets, etc.

Abstract: A process for producing agglomerates from fine-grained iron carriers and at least one binder as a charge material for a metallurgical process is shown. In at least one further agglomeration step, the agglomerates are coated with a layer, comprising iron carriers and at least one binder, and heated in such a way that the binder is cured in the region of the surface of the agglomerates. In a process for producing liquid pig iron or liquid primary steel products from charge materials and possibly additions and agglomerates, the agglomerates are preheated in a reducing zone, which has a preheating stage, in such a way that the agglomerates completely harden in the preheating stage.

Abstract: A process for producing pig iron or liquid primary steel products in a smelting unit (1), in particular a melter gasifier. Iron-ore-containing charge materials, and possibly additions, are at least partially reduced in at least one reduction unit (R1, R2, R3, R4) by means of a reducing gas. A first fraction of the at least partially reduced charge materials is melted down in the smelting unit (1), while carbon carriers and oxygen-containing gas are supplied, with the simultaneous formation of the reducing gas. The reducing gas is fed to the reduction unit (R1, R2, R3, R5) and, after the reducing gas has passed through the reduction unit, it is drawn off as top gas. A second fraction of the at least partially reduced charge materials is fed to a smelting reduction unit for reducing and smelting.

Abstract: The invention relates to a fluid separating device with a lower section with a fluid feeding device and a liquid discharging device, an upper section with a fluid feeding device and a gas discharging device, a contact device which is constructed in such a manner that gas, which rises from the lower section into the upper section, comes into contact with liquid which sinks from the upper section into the lower section. Thereby, the rising gases can be depleted of components which are soluble in said liquid. Furthermore, a measuring device for determining the quantity of liquid and/or the alterations thereof is provided.

Abstract: Vibration damper comprising a piston rod, which is guided with freedom of axial movement in a damping medium-filled cylinder and which carries a piston, which divides the cylinder into two working spaces. At least one of the two working spaces has a flow connection leading to a housing, in which a separating element separates at least one chamber from one of the two working spaces, where the volume of the minimum of one chamber in the housing has a size which is variable within defined limits. The separating element executes relative motion with respect to the housing, and is located in a permanent position with respect to the piston rod, whereas the housing is movable with respect to the piston rod.

Abstract: A piston rod with a piston is installed with freedom of axial movement in a damping medium-filled cylinder, where, as a function of the stroke position of the piston, a bypass connects the two working spaces separated from each other by the piston. The piston has at least one through-channel for at least one flow direction, which channel is at least partially covered on the outlet side by at least one valve disk, so that a first pressure-actuated surface to which pressure can be applied in the opening direction is present on the valve disk. In addition to the first pressure-actuated surface, the valve disk has a second pressure-actuated surface, which is separated from the first when the valve disk is closed and which can be actuated via the bypass, in which case the effects of the two pressure-actuated surfaces are additive.

Abstract: A method and apparatus of diagnosing leakage in a fluid power system including a fluid supply line operatively connected to a plurality of valves which are connected to a plurality of actuators. Flow signals generated by a flow sensor disposed in the supply line are processed to obtain fluid consumption over time values and signals used to change the state of the plurality of valves are processes to determine a plurality of episodes. Each of the plurality of episodes corresponds to a pressurization of a particular branch of a particular actuator. The flow signals and the signals used to change the state of the valves are combined to calculate a change in air consumption value for each valve change of state. The change in air consumption values for each episode are compared to a predetermined reference value to determine any deviation corresponding to a particular one of the plurality of episode.

Abstract: A method for transforming multi-dimensional data points into 1-dimensional values which are stored in a 1-dimensional index structure is disclosed. The data space is divided into a first plurality of pyramids each having a center point of the data space as a top and a (d-1) dimensional surface of the data space as a base, wherein the first plurality of pyramids is equal to twice the number of dimensions of the data space. Each pyramid is then divided into a second plurality of partitions. A Pyramid-value for each partition is then computed. Finally, each partition is stored in the index structure using the Pyramid-value as an index key.
