Abstract: A method for executing an application on a distributed system architecture having an application client for receiving input data and for providing output data; a local application server on the application client; at least one remote application server for receiving input data from the application client for processing input data for the application client and for returning processed input data to the application client; and an application manager for assigning the application to the local application server or to the at least one remote application server. The method includes determining a first round-trip time, determining a second round-trip time, determining a tolerance time for receiving and processing input data for the application, comparing the two round-trip times with the tolerance time, and assigning the application to the local application server or to the at least one remote application server based on the comparison.

Abstract: To take stock or monitor the inventory of stored objects or merchandise, a storage place or an optically scannable identifier, by which the object or the piece of merchandise can be identified, are assigned to a stored object or piece of merchandise. An electronic image is recorded at a given moment in time to determine whether the storage place is occupied or scan the identifier. A signal characterizing the recorded electronic image is transmitted to an evaluation unit via a mobile communication interface. A stock indicator that is assigned to the storage place or the identifier is adjusted by the evaluation unit based on the transmitted signal.

Abstract: The invention relates to a method for electrochemically processing a workpiece (61) in which a pulsating or alternating electrical voltage is applied between the workpiece and a workpiece electrode (62) which are arranged at a distance from one another in an electrolyte. A distance range is defined by precisely dimensioning the mean value of the applied pulsating voltage and of the voltage amplitudes measured with regard to this mean value. A double layer charge reversal on the workpiece which is sufficient for bringing about the desired electrochemical reaction results within said distance range, whereas workpiece areas situated at further distances do not experience a sufficient double layer charge reversal. The dimensions of the space between the workpiece and the workpiece electrode are proportioned in such a way that only points of the area of the workpiece to be processed lie within said distance range.

Abstract: Colored objects are represented by digitized color histograms which are used for the segmentation of digital color images. In this case, the binary values of the color histograms correspond to the decision as to whether a pixel can or cannot belong to a given object segment. Model-based parameterizations of these color histograms are preferred for the efficient execution of the segmentation. In particular, they permit adaptation of the color histograms to temporally varying lighting conditions with acceptable expense.

Abstract: A furnace closing mechanism for industrial furnaces is composed of a furnace door that can be latched to the furnace shell and a heat-insulating door fastened to the furnace door. This heat-insulating door renders the thermal insulation of the furnace interior gastight. Loss of material caused by friction is prevented by bayonet joints. The heat-insulating door provided by leaf springs and a threaded hub is screwed onto a threaded spindle, which is mounted on the furnace door and can be operated from the outside.

Abstract: A vacuum furnace for heat treatment of metallic workpieces wherein the heat conductors are formed as conduits fitted with bore holes and connected by electrical insulators to coolant gas distributor.

Abstract: A holding element for heating bars in industrial furnaces must be as flexible as possible so that it can accommodate the thermal expansion of the heating bars. Circular rings or circular-ring sectors provided with bores and made from a flexible graphite laminate plate are used for this purpose.

Abstract: A process for heat treatment of metallic workpieces by heating in a vacuum furnace followed by quenching in a coolant gas under above-atmospheric pressure and with coolant-gas circulation.

Abstract: There is described a loading apparatus for conveying charging grates in heat treatment furnaces has one or more chain strands which run in guide rails which also extend into the heat treatment furnace; at the end of the chain strands facing toward the furnace, the chain links have pivoting rocker arms on which there are secured support segments; the raising and lowering of the support segments is carried out by means of support blocks and retaining cams.

Abstract: There is provided a vacuum oven with a gas cooling device with which the heat treated charge for cooling is blown on with a cooling medium from nozzles arranged around it in which the nozzles in the heating chamber are arranged parallel to the axis of the oven and are placed on gas inlet tubes rotatable around its axis.
