Abstract: A centrifugal pendulum, in particular for arrangement on a drive shaft of an internal combustion engine, has a drive ring which can be mounted on a drive shaft for rotation therewith, and a synchronizing ring which is freely rotatable relative to the drive ring. The axis of rotation of the drive ring and the axis of rotation of the synchronizing ring are identical. The centrifugal pendulum further includes at least one pendulum body which is mounted movably on the drive ring. The pendulum body is kinematically coupled via at least one coupling element to the synchronizing ring such that, in the event of a rotation of the synchronizing ring relative to the drive ring in a first direction, the coupling element deflects the pendulum body toward the axis of rotation.

Abstract: A device having a surface displaceable in two spatial directions, including a carrier frame; a conveyor means disposed such that it circulates on the carrier frame in a first direction; a plurality of belt units, each belt unit being fastenable to the conveyor means in such a way that it is displaceable in the first direction, and each belt unit including: a first continuous belt that is disposed such that it circulates on the belt unit in a second direction; and a first driving roller for driving the first continuous belt in the second direction; each first driving roller being actuated by a dedicated drive; and each belt unit additionally has a second continuous belt that is situated on the belt unit parallel to the first continuous belt.

Abstract: A silicate raw material for ceramics containing alkali oxides, zinc oxide and silicon dioxide is characterized in that the three components alkali oxide, zinc oxide and silicon dioxide are present as calcined three-component silicates in a molar ratio of from 1:1:2 to 1:2:6, preferably in integral molar ratios, are employed.
