The invention relates to a syringe-like mixing device, comprising a housing, in which a mixing chamber is formed, a piston, which can be slid in the mixing chamber from the proximal side, and a mixing element, which can be operated from the distal side. In order to ensure simple operation, the mixing device has a sealing cap, which seals the distal open end of the mixing chamber and which has a passage opening, through which an operating rod for the mixing element is guided. The sealing cap can be completely removed from the housing together with the operating rod and the mixing element. In order to discharge the mixing product, a second sealing cap can be placed onto the housing. Accessory parts can be connected to said second sealing cap. The mixing product can then be discharged as with a conventional injection syringe.
A rearview mirror assembly for a vehicle is provided. The assembly has a holding component and clamping parts to clamp the mirror assembly to the holding component. Alternative embodiments of the holding component and clamping parts are also disclosed.
A chain drive for a link chain of mining conveyors or mining extraction machines, in particular for scraper chain conveyors, includes a drive shaft. The drive power or the drive torque is introduced into the link chain by chain tooth elements. The chain tooth elements are set directly in the drive shaft in seats. For that purpose, the chain tooth elements have a lower coupling portion for interlocking engagement in the seats in the drive shaft. Accordingly, a separate chain wheel is unnecessary.
