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: An insulating strip is disclosed. The insulating strip includes a support layer and a plurality of insulating material strips secured to the support layer where the plurality of insulating material strips are spaced apart from each other.

Abstract: The invention proposes a finger lever (1) for actuating a gas exchange valve (4) of an internal combustion engine, said finger lever (1) being composed of side walls (11), a valve contacting element (12), a roller axle (8)/roller (9) and a joint socket element (13). According to the invention, the side walls comprise through-openings (15, 16) that are aligned to each other in pairs and in which each of the valve contacting element and the joint socket element are retained after the manner of a pin and bore connection by respective axle ends or axle stubs (18, 19) pointing in a transverse direction of the side walls.

Abstract: The chain according to the invention comprises a plurality of linking members arranged one behind the other so as to form a closed loop, each linking member comprising two end links intended to come into contact with truncated surfaces of the continuously variable transmission, as well as intermediate links, while pivot pins are provided, allowing the mutual pivoting of two adjacent linking members, which extend through the openings made at least in these intermediate links.

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. Each of the offset chain gears has assigned thereto a separate track of the multiple-track chain due to the lateral offset. The tip diameters of the offset chain gears are overlapping.

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: The invention relates to a method and a device for interlocking stackwise plastic bags, especially bags for automatic machines, by welding, wherein welding is effected by an interlocking device (21) integrated into the grip hand (17) of a robot (16) with the purpose of simplifying welding.

Abstract: A link chain having chain links interconnected at respective hinge points by a hinge bolt, at least one bearing bushing arranged on a hinge bolt, at least one roller arranged on said bearing bushing such that it is rotatable about the hinge bolt, and an axial retaining device attached to the hinge bolt and used for axially securing the bearing bushing and the roller. 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: In a mechanical chain tensioner (K) which comprises a molded part having fastening openings and abutments, as a basic body (G) on which a tension bracket (B) can be mounted on the abutments, the basic body (G) is an integral molded part of filled or reinforced, injection-moldable plastic.

Abstract: In a tension or guide rail (S) for a chain drive, especially in an internal combustion engine, with the rail comprising a carrier (T) formed from filled or reinforced plastics for carrying a slideway lining body (B) of plastics which is connected to the carrier in form-fit and friction-locked fashion, the carrier (T) and the slideway lining body (B) are separately prefabricated constructional units, and the prefabricated slideway lining body (B) is subsequently connected mechanically to the prefabricated carrier (T) by means of form-fit and friction-locking elements.

Abstract: There is described a hydraulic tensioner (1, 101) for endless transmission elements, in particular a chain tensioner for internal combustion engines. The tensioner includes a housing (2, 102), a pressure chamber (3, 103) arranged in the housing, a piston (4, 104) which is movable in the pressure chamber (3, 103), a hydraulic fluid supply to the pressure chamber (3, 103), a check valve (20, 120) which is arranged within the hydraulic fluid supply and is acted upon by pressure in the pressure chamber (3, 103), and a means (11, 111) for automatically reducing the pressure in the pressure chamber (3, 103). To provide such a tensioner with a pressure-relief valve (11, 112) for automatically reducing pressure in the pressure chamber (3, 103), i.e., in a manner which is simple under constructional and technical manufacturing aspects and also reliable, the check valve (20, 120) should be connected to the valve member (12, 122) of the pressure-relief valve (11, 111).
