Abstract: Pneumatic tire, particularly a two-wheeler pneumatic tire, such as a bicycle tire, which includes at least one rubberized casing that is anchored in beads by wrapping bead cores. A tread is provided. An outer covering has a layer thickness of less than or equal to 0.5 mm. The outer covering has a high tear resistance and extends at least over the tread.

Abstract: A wiping device for wiping cover plates of the headlights of motor vehicles includes a wiping arm carrying a wiper blade and swingable over the cover plate being wiped, and a drive shaft which is releasably connected to the wiping arm by means of an adapter. The wiping arm is comprised of two halves hinged to each other by a hinge the axis of which extends in a plane parallel to the cover plate being wiped. A spring is arranged between two hingeable halves of the wiping arm. The wiping device can be completely moved out from the path of light beams emitted by the headlight.

Abstract: The discharge end of the rotary kiln (24) is surrounded by and gas-tightly sealed to a stationary kiln head (2), which contains a rigid, cooled, inclined grate (1). A container (3) for collecting oversize is mounted on the kiln head (2) and is provided at its discharge end with a gate valve (4). The collecting container (3) is surrounded by and gas-tightly sealed to an outer container (5) and is provided with a gas-tight flap valve (6) and with a fitting (7) for a gas-tight connection to a transport container (8). Under the grate (1) the kiln head (2) constitutes a buffer bin (9) for the particles falling through the grate. The buffer bin (9) is succeeded by a batching bin (10), which is provided with a gas-tight upper shutoff valve (11). On its discharge side, the batching bin (10) is provided with a gas-tight lower shutoff valve (12) and with a fitting (13) for a gas-tight connection to a transport container (14).

Abstract: In order to reduce the wear and to facilitate the replacement, a nozzle block comprises a mounting plate which is connected to the kiln shell, a nozzle tube which extends in the mounting tube and defines a clearance with the mounting tube and with the kiln lining, an abutment surface provided at the lower end of the nozzle tube and engaged by the orifice plate and which is clear of the body of the nozzle tube, a retaining tube which extends in the nozzle tube and defines a clearance with the nozzle tube and with the orifice plate, a gas feed duct attached to the side of the mounting tube and a cover on the mounting tube.

Abstract: The invention concerns a rotating round cooler for the cooling of hot loose material, especially hot iron ore sinter, consisting of a ring-form base plate, which is supported with treadrollers on a circular rail, a holding apparatus fastened to the base plate, a cooling chamber which is fastened movably to the holding device with inner and outer walls permeable to gas, whereby at least the bottom edge of the outer wall is located some distance from the base plate, a horizontal passage to the center of the cooler, a charging apparatus above the cooling chamber, a pick-off above the base plate and in the midst of the cooled material, a drive device for the rotary movement of the cooler, inlet devices for the gaseous cooling medium on the inside of the holding device, as well as blowers for the production of the pressure required for the cooling medium.
