    摘要: A braking mechanism includes a wedge selectably engageable with a guide rail, and a frictional surface defined on the wedge configured for selective engagement with the guide rail in an overspeed condition. The frictional surface includes a friction coating of polycrystalline blocky diamond material. An elevator system includes an elevator car, a guide rail along which the elevator car travels, and a braking mechanism located at the elevator car and selectably engageable with the guide rail to slow or stop travel of the elevator car along the guide rail. The braking mechanism includes a wedge having a frictional surface configured for selective engagement with the guide rail in an overspeed condition. The frictional surface includes a friction coating of polycrystalline blocky diamond material.

    摘要: A soldering apparatus, in particular a reflow soldering apparatus, for the continuous soldering of printed circuit boards along a transport direction, including a process channel that has a preheating zone, a soldering zone and a cooling zone, and further includes a base body and a cover hood movable between a closed position and an open position, wherein nozzle plates, fan units with fan motors, air ducts that conduct the process gas, filter elements and/or cooling elements are provided in the base body. The soldering apparatus further includes a drawer, which extends along a pull-out direction running transversely to the transport direction, is provided in the base body, with a bottom, a front wall and a rear side. Air ducts for conducting the process gas, at least one replaceable filter element in a filter region and at least one cooling device are provided in the drawer.
