Patent DE-3831515-A1 (DE)
Title: Torsional vibration damper
Inventor: KAIFLER MARTIN
IPC: F16D3/80
Filed: 1988-09-16
Abstract: The invention relates to a torsional vibration damper in which, under the action of axially elastic spring elements on the coupling members between the damper halves, relative rotations of the damper halves lead to an axial extension of the coupling members. The spring elements are designed as axially elastic diaphragm discs which also transmit torques between the damper halves, making possible the construction of simple and economical torsional vibration dampers composed of a small number of individual components. The torsional vibration damper operates in a jerk-free manner and is virtually wear-free because, due to the use in its construction of diaphragm discs which act on rolling elements, only small frictional forces occur. In the case of use of the torsional vibration damper in a clutch, transmission of large torques with large angles of rotation is possible for a small clutch diameter. By the formation of chambers filled with damping fluid adjoining the diaphragm discs, damping of the rotary motions of the damper parts based on displacement of fluid can be achieved in a simple manner. <IMAGE>

Patent DE-3911237-A1 (DE)
Title: Continuous casting mould
Inventor: EVERTZ EGON
IPC: B22D11/059
Filed: 1989-04-07
Abstract: The invention relates to an adjustable continuous casting mould, particularly for casting slabs. The mould consists of copper walls, which are adjusted to the dimensions of the slabs to be produced and are then clamped fast. The lower areas of the side walls facing the steel are coated with nickel in order to increase their life. Since there are difficulties with these moulds in moving the walls into a position corresponding to predetermined dimensions, once given, and also in maintaining this position during the clamping operation which has to be carried out, the invention envisages nickel-coating that part of the side-wall plate (against which the adjacent plates are supported) which lies above the coating level. This ensures that clamping takes place between pairs of surfaces composed of copper and nickel over the entire height of the mould. In this case, the desired dimensions set remain unaltered even during the clamping of the mould and, as a result, satisfactory dimensions of the slabs to be produced are guaranteed.
