Abstract: A storage housing for an electrical energy store of a motor vehicle includes at least one housing part having a circumferential sealing flange, at which the housing part can be connected to at least one additional housing part of the storage housing, The one housing part is formed by a steel frame which is connected to a closing part made of a light metal material, in particular an aluminum material. In order to create a housing part which is optimized in terms of its weight and also in terms of simplicity and sealing, it is provided that the steel frame is designed as a single-piece shaped component made of a steel material.

Abstract: The invention relates to a ventilator which comprises a pneumatic system for conveying ventilation gas in a flow direction (d) to a patient or from a patient, and further comprises at least one light source which is directed, in emission direction (r), at the ventilation gas and/or at a display area and/or at the pneumatic system.

Abstract: Embodiments described herein generally relate to a grinding disc is being rotatably drivable around an axis of rotation. The grinding disc has a front side as well as a rear side facing away from the front side. The grinding disc further includes a multi-layered circular grinding blank packet with a plurality of circular grinding blanks. The grinding blanks are flatly stacked over each other along the axis of rotation and in which each grinding blank includes a central through opening. The central through openings form together a recess of the circular grinding blank packet. Wherein the grinding disc has a backing plate, which is arranged in the recess, and the circular grinding blanks each are fixed individually to the backing plate.
