Abstract: A device for cleaning workpieces with a steam jet is proposed, with a special steam generator in which the steam is generated in a hollow cylindrical core, whose outer side is heated and onto whose inner side the water to be vaporized is sprayed by means of a nozzle. The steam generator has a supplementary heating device with a heatable body having a cavity through which steam generated upstream can flow for post-heating it, in order to generate dry steam for dry steam cleaning. An automated cleaning system with this steam generator is also proposed. The device can be adapted flexibly to the requirements of automated synchronized production and requires, in particular, less energy and floor space. The invention can be used, among other things, in industrial cleaning in manufacturing systems engineering, in particular in the production of automotive parts.

Abstract: A complete passenger service unit (PSU) that includes a ducted housing that cools a stepped-down transformer from native 28 V DC aircraft power to 12-36 V DC to power and ultraviolet light producing ultraviolet wavelengths between about 200 nm and 235 nm. The ventilation air provided to all PSU stations is fed into the ducted housing to eliminate the need for additional fans or other cooling means for the transformer.

Abstract: A flexible leak testing machine for tightness testing of a cylinder head, an engine block or similar workpiece has at least one sealing plate, a machine frame with at least one workpiece holding device for the workpiece and an adjusting device with a first drive for bringing together the workpiece and the sealing plate into a test position. The leak testing machine is flexibly usable in that it includes a changeover device for sealing plates. The changeover device has an adjustable holding arrangement on the machine frame, with sealing plate holders and an associated drive for sealing plate changeover.

Abstract: In conventional methods for cleaning the surface of workpieces in automatic production by means of vapor or hot water, the temperature of workpieces can undergo such a change that the dimensions exceed tolerances as a result of the thermal expansion, and subsequent mounting or processing is only possible after a thermal treatment step. Cleaning is performed by scanning a jet of vapor or hot water over the surface of the workpiece and carrying out this process at reduced pressure, so that the residues of condensed vapor or water that are present on the surface evaporate at least partially, and thereby extract from the workpiece heat that has been supplied by the vapor or the hot water. Preferably, the cleaned surface is at the same time dried.

Abstract: The invention relates to elastomer sandwich systems containing at least two components, wherein one component is (i) a thermoplastic polyurethane functioning as a cover layer and, adhering thereto over its area, the second component is (ii) a noncellular cast polyurethane having a density of from 800 to 1800 kg/m3 functioning as a carrier layer, wherein at least one component of the elastomer sandwich system has a tear propagation resistance in accordance with ISO 34-1 of from 30 kN/m to 85 kN/m and an abrasion loss in accordance with ISO 4649 of from 50 mm3 to 5 mm3 and in addition at least the two components have a rebound resilience in accordance with DIN 53512 of 35%-70%, and a process for the production thereof. The invention further relates to metal composite elements containing elastomer sandwich systems, a process for the production thereof and the use thereof as lining elements in the transport sector and mining and mine sector, in particular in hoppers and conveyor belts.

Abstract: An industrial installation and process are provided for cleaning workpieces, in particular engine components or transmission components. The installation has a housing enclosing a workspace and an industrial robot mounted inside the housing, in particular on a platform. An air recirculation device having a vapour condenser and ductwork with one or more intakes for admitting vapour-charged air from the workspace and one or more exits for returning dehumidified air to the workspace. The vapour condenser preferably includes a heat recovery unit. The vapour condenser is arranged at a level below the top of the housing, preferably below the platform and/or each of the one or more intakes is arranged at a level below the upper half of the workspace, preferably on or below the platform.

Abstract: An industrial installation and process for cleaning workpieces, in particular for cleaning components of engines and transmission components using a cleaning liquid, includes a first filter which is a backwash filter (17) for receiving contaminated cleaning liquid. A second filter (18) is arranged for receiving backwashed contaminated cleaning liquid from the backwash filter (17), and for removing solid matter, e.g. chips, from the contaminated cleaning liquid. An oil separator (21) is arranged for receiving contaminated cleaning liquid and for removing oil from the contaminated cleaning liquid. The oil separator (21) is fluidly connected to the second filter (18) and arranged for receiving the contaminated cleaning liquid directly from the second filter (18). The arrangement of the oil separator (21) directly following the second filter improves the filtering efficiency of the system by reducing the flow path distances of the contaminated cleaning liquid.

Abstract: A method and an installation for high-pressure liquid jet deburring are proposed, in which a machined workpiece (44) is deburred by means of a high-pressure/high-speed liquid jet from a high-pressure jet nozzle (30) that is connected to a high-pressure liquid circuit (32). According to the invention, the deburring receptacle (16) has a flooding inlet (48) connected to a liquid supply circuit for flooding the deburring receptacle (16) with cleaning liquid and is configured to contain a bath (46) of cleaning liquid during operation. Prior to deburring, the deburring receptacle (16) is flooded with cleaning liquid via a flooding inlet (48) of the deburring receptacle. Further according to the invention, the machined portion (44) is deburred after flooding and by means of a liquid jet without gas sheath such that the high-pressure/high-speed liquid jet and at least the machined portion are immersed in a bath of cleaning liquid during deburring.

Abstract: A tool for attaching valve keys to a valve stem includes an elongated holder with a longitudinal axis, an inner hollow space and an end opening. An elongated core is arranged in the hollow space of the holder coaxially to the longitudinal axis. An elongated recess for receiving a substantial upper portion of the valve stem is provided in the end region of the core coaxially to the longitudinal axis. The recess of the core issues into the end opening and has a depth which is greater than or at least equal to the axial distance between the end and the annular groove of the valve stem. The core at least partially covers the annular groove, such that the valve keys can be supplied to the lateral surface of a valve stem underneath the annular groove and incorrect engagement can be avoided.

A mechanism for guiding the winding and unwinding of the line wound in a spool. The mechanism ensures that the line is properly wound when the spool is substantially coaxially aligned with the line in order to provide an ergonomically compatible handling of the device. A motor assembly with step-down and step-up gear assemblies that provide the rotational energy to the spool assembly and the reciprocating movement to a traveling pin with a line guiding roller at its distal end. A leg assembly that doubles as a storage compartment for back-up batteries is rotably mounted at one end to the housing assembly.
