Abstract: An aperture unit for a particle beam device, in particular an electron beam device, is disclosed. Deposit supporting units are arranged at the aperture unit, with which deposit supporting units contaminations can be bound in such a way that the contaminations can no longer deposit at an aperture opening of the aperture unit. Coatings which can be arranged on the aperture unit make it possible to reduce interactions which cause contaminations to deposit at the aperture opening.

Abstract: An exemplary turbocharger system for an internal combustion engine is provided. The turbocharger system includes a first turbine and a second turbine. The first turbine is in fluid communication with the internal combustion engine. The first turbine receives a first portion exhaust gas discharged from the internal combustion engine and provides a first turbine exhaust gas. The second turbine is in fluid communication with the first turbine via an inter-stage channel. The inter-stage channel transports the first turbine exhaust gas from the first turbine to the second turbine. The inter-stage channel is in thermal connection with an exhaust gas recirculation channel defined between an inlet and an outlet of the internal combustion engine. The first turbine exhaust gas flowing through the inter-stage channel is capable of being heated by a second portion exhaust gas discharged from the internal combustion engine and flowing through the exhaust gas recirculation channel.

Abstract: An exemplary compressor is provided. The compressor includes a plurality of blades, a hub defining a front surface and a back surface, and a first flow restriction structure provided at the back surface of the hub. The plurality of blades are arranged in a predefined manner on the front surface for receiving input air flow at a first pressure and compressing the input air flow to provide an output air flow at a second pressure higher than the first pressure. The first flow restriction member is configured for preventing at least a portion of the output air flow at the second pressure from entering into the back surface of the hub to reduce an air pressure at the back surface of the hub.

Abstract: A radial magnetic bearing for magnetic bearing of a rotor has a stator which includes a magnetically conductive stator element, arranged circulating around a rotor. The stator element has recesses running in the axial direction of the stator element in which electrical lines from coils are arranged, wherein magnetic fields can be generated by the coils which hold the rotor suspended in an air gap arranged between the rotor and stator.

Abstract: A particle beam system 1 for cleaning itself comprises an irradiation system to direct electromagnetic radiation onto the surfaces to be cleaned and a supply system 61 to supply a precursor gas to the interior of the vacuum chamber 11 of the particle beam system 1. The precursor gas is activated in a vicinity of the surfaces to be cleaned and is converted into a reaction gas which reacts with the contaminants present on the irradiated surfaces such that said contaminants may be pumped out then.

Abstract: The object of the invention is to provide an economical vane-type camshaft adjuster system that meets the various requirements of various motors. For this purpose, according to the invention a modular system is provided for the valves of a vane-type camshaft adjuster system. Two different embodiments of valves are proposed. With one embodiment, a valve with mid-locking and without mid-locking may be constructed using the same bush. With the other embodiment, a valve with and without special utilization of the camshaft alternating torques may be constructed using the same bush.

Abstract: The present invention relates to an arresting brake (10) for arresting at least one rotatably mounted component (12, 14) with respect to a housing (32), and is suitable in particular for use in an agricultural or industrial utility vehicle. The arresting brake (10) comprises an electromagnet (26), two armature components (40, 42) and two rotatably mounted components (12, 14). The electromagnet (26) preferably has a core (26) and a coil (30; 50, 52). The armature components (40, 42) are arranged such that they can move in relation to the electromagnet (26) and are rotationally fixed with respect to the housing (32). The electromagnet (26) is arranged between the armature components (40, 42), in order to arrest the rotatably mounted components (12, 14) using the arresting brake (10), in each case an armature component (40, 42) can be engaged with, in each case, one rotatably mounted component (12, 14).

Abstract: A control lever controls movement of a system to be controlled. The control lever includes a manually operable handgrip attached to a platform. At least six connecting elements are arranged between the platform and a fixed console. Length sensors sense the length of the connecting elements, and/or force sensors sense forces acting on the connecting elements. A control unit evaluates the sensor signals and generates a control signal for controlling movement of the system. The connecting elements are be arranged in the form of a hexapod. The connecting elements may be telescoping members or rigid fixed length members.

Abstract: A gas-tight joint for pipe linings and risers inside a bore, consisting of a neck with an outside thread and of a matching collar with an inside thread, with a groove in the vicinity of the thread on the collar and/or of the thread on the neck to accommodate a deformable gasket that, when the joint is screwed tight, is demarcated and deformed by the base of the groove in the neck and/or in the collar and by the contour of the thread on the other component. The cross-sectional area demarcated by the base of the groove in the neck and/or collar and by the contour of the thread on the other component once the two components have been screwed together remains constant along the groove and is equal to or larger than the cross-sectional area of the deformable gasket before the components are screwed together.
