The invention relates to an air guidance system having an air guidance housing and an air passage grating fastened thereto, the air passage grating being held on the air guidance housing by means of a snap-lock connection. In order to simplify maintenance of such an air guidance system it is provided according to the invention that the air passage grating carries at least one latch having a snap-in shoulder that can be engaged in a snap-lock seat of the air passage grating and that the air passage grating pivotally accommodates a handle in a bearing seat, said handle disengaging the latch from the snap-lock seat when set from the locking position to the unlocking position.
摘要:
A control device for a brake system of a rail vehicle, wherein the brake system includes a friction bracket device which is dependent on frictional engagement. The control device determines a braking effect applied during a braking process on the basis of a brake pressure or brake current and at least one further parameter. Also disclosed are a brake system having such a control device and a method for determining a braking effect.

The invention relates to a fan-and-filter unit to be mounted in the wall of a switch cabinet or housing, and includes a fan unit inserted in a fan housing, a filter mat arrangement mounted upstream of the fan unit and a fan cover immobilizing the filter mat. An embodiment advantageous for operation of the fan-and-filter unit may be provided where the fan-and-filter unit has a filter mat monitoring unit which is designed to detect the service life and/or a degree of soiling of the filter mat arrangement and which includes an insert integrated into the fan housing or the fan cover and having an illuminated display visible from the exterior of the fan cover facing away from the fan unit and being designed to display at least exceeding of a predetermined or predeterminable service life and/or a predetermined or predeterminable degree of soiling.
摘要:
A cover for a roller having at least one roller (2) for transporting a substrate (1) in a deposition system and at least one cover means (6), wherein the roller is retractable away from the substrate and the cover means is adapted for at least partly covering the retracted roller against contamination by a substance present in the deposition system. The cover for a roller has the advantage that the uptime of the deposition system is increased.
摘要:
Provided is a hypergolic bipropellant formed by combining a IL fuel having a dicyanamide anion and a nitrogen-containing, heterocyclic-based cation with an oxidizer for such fuel.
摘要:
A compressor includes a motor having a rotor mounted to a free end of a crank shaft and a stator in a motor housing, and a bearing assembly supporting the crank shaft on the crank shaft housing adjacent the motor housing. The bearing assembly includes a bearing housing mounted to the crank shaft housing and including a bore; and a pair of spaced bearings mounted in the bore of the bearing housing and receiving the crank shaft. The space between the bearings is selected to allow the free end of the crank shaft to deform in synchronization with the movement of the stator and maintain a gap between the rotor and stator over the operating range of the motor.

摘要:
An apparatus and method are provided for improved utilization of a sputter target in the longitudinal end regions. The focus of erosion in the end regions is widened, thereby extending the useful life of the target. This provides improved efficiency and reduces waste because a greater proportion of the target material in the more expansive central region can be harvested, because the target is utilized for a longer period of time.
