Abstract: An autothermal direct air capture system (ADAC) is disclosed. The ADAC includes a chamber, a water reservoir, and a sorbent that releases water under ambient conditions, binds water under a first moisture level higher than the ambient moisture level, binds CO2 under ambient conditions, and releases CO2 under at least one of an elevated temperature and the first moisture level. The ADAC is movable between a capture configuration and a regeneration configuration, the capture configuration including the sorbent being exposed to a gas volume having CO2 under ambient conditions, the sorbent binding with CO2 while desorbing water, the sorbent selected so the sorbent material extracts heat while the ADAC is in the capture configuration, resulting in the thermal charging of the sorbent. The regeneration configuration includes the sorbent inside the chamber and in contact with water, the sorbent releasing carbon dioxide while binding water and depositing heat into the chamber.

Abstract: The present invention relates to a centrifuge rotor, in particular a laboratory centrifuge rotor, including a rotor body, wherein the rotor body at least partially includes a porous metal or a porous metal alloy and an armoring located radially outside with respect to the rotation axis of said rotor body is provided. The centrifuge rotor allows centrifugation to be performed in a shorter time than previously and at a higher rotational speed. This results, inter alia, in higher RCA (relative centrifugal acceleration) values and thus in a very rapid separation of the constituents of the substances to be centrifuged.

Abstract: The present invention relates to a chain drive, in particular camshaft/camshaft drive for an automotive engine, the chain drive comprising at least two chain gears and a drive chain. Such a chain drive shall be made more compact without excessively great losses in its low-noise characteristics. To this end at least two chain gears are arranged in laterally offset relationship with one another in axial direction. The drive chain is a multiple-track chain.

Abstract: A gearwheel, in particular a chain wheel, for the transmission of torque from one shaft to another, has a form-locking fastening device for fixing it on the shaft in a defined position. The fastening device is a bowl-shaped driver part and has a damping device for the damping of torsional oscillations, the damping device including of a leg spring with two legs which are angled parallel to one another and surround, under prestress, a driver extension on the driver part and a driver nose on the gearwheel. The angular position of the gearwheel on the shaft is defined by the force of the prestressed leg spring, the torsional oscillations bringing about a deflection of the gearwheel on the shaft through a particular angle of rotation in both directions of rotation and therefore being smoothed. The cost-effective and space-saving form of construction of the gearwheel, which forms a structural unit with the driver part and the leg spring, is advantageous.

Abstract: A switch device for switching an electrical connection between two connection parts is disclosed. Conventional switch devices comprise a contact lever having a switch contact, the flow of current taking place by way of the contact lever when the switch device is closed. To achieve a rapid switching process, a low mass inertia of the contact lever is required. However, this generally leads to a lower current capacity. By arranging the lever-side switch contact on a separate electrical connection device, it becomes possible to separate the function of current conduction from the function of contact guidance. Since the contact lever therefore no longer performs any current-conducting function, it may be optimized in mechanical respects exclusively.

For reducing vibrations in the link chain, a bearing bushing is provided having an axial damping area on at least one end face area thereof, the damping area being formed integrally with the bearing bushing, and the bearing bushing being arranged such that the damping area rests against the axial retaining device.

Abstract: The invention pertains to a contact lever for an electrical switch designed for automatic adjustment of the main contacts. During assembly the pivot shaft is inserted in an oblong opening in the contact lever. The switch position is changed from open to closed by rotating the contact lever on the pivot shaft.

The conical shoulders and chamfers comprise a portion of the bearing surface between the contact lever and the pivot shaft. A sliding bearing pair is formed during switch operation wherein the contact lever is limited to a centrally aligned position in the open position and allowed additional freedom of motion at the end of the closing operation. The additional freedom of motion allows for precise automatic contact alignment.

The bearing is insertable into the first opening portion in a direction different from the direction of compression and then movable in the direction of compression to produce an interlock connection with the second opening portion of the opening.
