Abstract: Modem rotary machine production requires built-in fault detection and diagnoses. The occurrence of faults, e.g. increased friction or loose bonds has to be detected as early as possible. Theses faults generate a nonlinear behavior. Therefore, a method for fault detection and diagnosis of a rotary machine is presented. Based on a rotor system model for the faulty and un-faulty case, subspace-based identification methods are used to compute singular values that are used as features for fault detection. The method is tested on an industrial rotor balancing machine.

Abstract: An apparatus is proposed for the dosed dispensing of a fluid, especially an infusion fluid, comprising a housing (1) with a fluid chamber and a pressure medium chamber (3) by which a flexible wall (4) of the fluid chamber can be pressurized from the outside with a pressure medium. In order to provide a re-useable infusion pump with especially simple means it is proposed that the housing (1) consists of two mutually detachably joined housing parts (6, 7), of which the one comprises the pressure medium chamber (3) and the other receives in an exchangeable manner the fluid chamber configured as a leak-proof infusion bag (2), and that the housing part (6) with the pressure medium chamber (3) is sealed by a membrane (5) against the housing part (7) receiving the infusion bag (2) and is connected to a gas pressure source (11).

Abstract: A remote control electrical device which can communicate with a remote control device. The electrical control device is adapted to fit into a housing which fits into a wall mounting. The remote control electrical device can comprise a control circuit disposed in the housing, a transmitter disposed in the housing, a receiver disposed in the housing wherein said transmitter and said receiver are in communication with the control circuit. There is also a support plate having an inside face facing into the housing and an outside face facing away from the housing body. The support plate is coupled to the housing, wherein there is also an antenna disposed on the outside face of the support plate. This antenna does not receive any power-line AC frequencies or DC, instead it is capacitively coupled to the rest of the electrical components and disposed on the outside face of the support plate.

Abstract: The invention relates to a valve train for internal combustion engines, comprising a camshaft and valve actuation elements for one or more valves, the elements being located in the cylinder head. The aim of the invention is to provide a valve train for an internal combustion engine, with which a reliable stroke adjustment of the valves can be made, without the need for complex technical resources, while at the same time allowing a forward or rear displacement of the valve orifice region. To achieve this, in order to modify the valve stroke curve, the contact point between the transfer member and the cam can be displaced along the periphery of the cam and the contact point between the transfer member and a control curve of the support body can be displaced, forcing the part of the transfer member that interacts with the cam to be guided, by shifting the transfer member in relation to the camshaft.

Metallic U-shaped profiled rails that are open towards the outside are provided between the props along the bottom edge of the load support. The props can be removably fixed to the bottom face of the bottom part of the load support and are provided with a support area for the corner areas of the bottom part as well as an edge which rises vertically from the support area and encloses the edges of the load support at a right angle, pegs being molded onto the free final leg surfaces of the edge to accommodate and fix the U-shaped profiled strips.

Abstract: Disclosed is a connecting rod for a combustion engine, comprising a small connecting-rod eye that is provided with a plain bearing surface and is used for accommodating a piston pin, and a large connecting-rod eye which is provided with a plain bearing surface and embraces a crankshaft journal. In order to very effectively and inexpensively prevent the piston pin and the crankshaft journal of the connecting rod from jamming and wearing off, a self-lubricating coating made of a thermally cured resin which contains embedded solid lubricant particles is applied directly to at least one of the plain bearing surfaces by means of rotary atomization.

Abstract: Disclosed is a multipart, cooled piston for a combustion engine, comprising, in a radially outward direction, an annular cooling duct located on the bottom side that faces away from the piston head. The cooling duct is closed by a cooling duct cover which is embodied as a ring. The cooling duct cover is provided with a tongue in the radially inner zone. The tongue engages into a recess that is molded into the bottom piston part, thus preventing the cooling duct cover from rotating relative to the piston during assembly as well as during operation.

Abstract: A method for the analysis, control, automation, and information management of life-cycle processes of technical products includes an engineering process, an analysis process, a test process, and accesses an information system. The engineering process, the analysis process and the test process, which includes a plurality of test modules, have connections for information exchange exclusively to the control process and information system. For every test of the test modules, the scope and form of the input and output values are determined by data stored in the information system. The data that are input into the engineering process and determined, and the specified values, are processed by the process control, which determines all of the tests to be carried out. The results are passed on to the process control. The analysis process determines if data and specified values input in the engineering process have been reached by a numerical or numerical/statistical calculation.

Abstract: In a method of rehabilitating a ballast bed of a track by excavating contaminated ballast and conveying the excavated contaminated ballast by a first conveyor band unit to a screening unit for cleaning the excavated contaminated ballast, the ballast bed is rehabilitated selectively, in dependence on the degree of contamination of the ballast, in a first or second operating stage. The first operating stage comprises the steps of excavating an upper layer of the ballast by a first excavating device which precedes a second excavating device, in an operating direction, and conducting the excavated upper ballast layer to the first conveyor band unit while, at the same time, the remainder of the ballast is excavated by the second excavating device and is conducted to a second conveyor band unit for disposal.

Abstract: The instant invention overcomes the difficulties encountered with respect to mounting electrical wiring devices to a common box and then positioning the devices relative to each other prior to attaching a wall plate. Some of the difficulties encountered are positioning the wiring devices to be in alignment with each other, locating the wiring devices to be parallel to each other, adjusting the spacing between the different devices to be equal and uniform and fixing all of the devices to be flat against the wall. The alignment pins, when engaged by the close clearance locating openings, accurately positions the wiring devices to allow a wall plate to be placed around the wiring devices without requiring any initial or subsequent adjustment. Each set of alignment pins on the alignment plate can be located on a vertical axis which accurately defines the center for the wiring device. The opening in the wiring device receives and holds captive a set of alignment pins.
