Abstract: A suction gripping device for picking up a plurality of substrates which are flat and flexible includes: a base body, which defines a plane; at least one gas suction vacuum module which is arranged on the base body and has at least one gas suction opening configured for withdrawing gas by suction and for generating a first vacuum so as to suction a respective one of the plurality of substrates against the suction gripping device; and at least one gas ejection vacuum module which is arranged on the base body and has a gas ejection opening configured for ejecting gas and for generating a second vacuum so as to suction the respective one of the plurality of substrates against the suction gripping device.

Abstract: Systems and methods for object-based data storage are provided. There may be a read/write cache configured to cache objects to be written to an object-based data storage. A document in the read/write cache may have a lock state set to unlocked, thereby allowing the document to be deleted. Or, the document in the read/write cache may have a lock state set to locked, thereby preventing deletion of the document.

Abstract: An exhaust gas aftertreatment system with an exhaust gas inlet, at least two exhaust gas aftertreatment elements, and a flow chamber. The exhaust gas inlet, the at least two exhaust gas aftertreatment elements, and the flow chamber are arranged relative to one another and fluidically connected together such that exhaust gas flowing through the exhaust gas inlet into the flow chamber can be distributed to the at least two exhaust gas aftertreatment elements. The exhaust gas passes through at least one first of the at least two exhaust gas aftertreatment elements along a first flow direction, and the exhaust gas passes through at least one second of the at least two exhaust gas aftertreatment elements along a second flow direction, wherein the first flow direction and the second flow direction are oriented at least diagonally to each other, preferably anti-parallel to each other.

Abstract: The invention concerns a Wells turbine, comprising a hub with a plurality of rotor blades having a drop-shaped profile orienting from a profile nose; the rotor blades are attached to the hub in a rotary fashion by means of a foot part such that the rotor blade angle is variable with respect to the plane of rotation, wherein the associated rotational axis intersects the chord for each profile section in a threading point, which is located in a region between the profile nose and the aerodynamic center of the profile; the adjustment of the blade angle is made passively by the equilibrium occurring during the operation of the wells turbine between the aerodynamic torque, acting on the rotor blades, and the centrifugal torque, wherein the average density of the rotor blade is selected to be less than 2700 kg/m3 and/or the mass distribution within the profile is selected such that the surface centrifugal torque of the rotor blade is reduced relative to a profile made from a solid and/or the surface centrifugal to

Abstract: A device for fixing an additional device, such as a scope or laser sighting device, to a firearm free of play and able to accommodate the ever-changing (recoil and spring-back) forces that occur on the engaging mechanism of the fixing device. In addition to a recoil lug contacting a first stop surface of a first groove, a further adjustable stop is provided, engaging a stop surface in a different groove in a direction opposite, along the line fire, to the first stop surface.

Abstract: A golf bag includes a bottom part, a cylinder part with stabilizing longitudinal webs, a head part, a support device with toggle lever mechanism or another mechanism and a clamping system for folding out and folding in support legs, a pull-out grip and a belt system. The golf bag combines in itself all components for stable standing, rolling, sloped support, carrying on the shoulder or on the back and for transport in the lying or upright position without additional actions on the part of the golfer. The golf bag is easy to handle and can be transported in a compact manner.
