Abstract: A torsional vibration damper housing includes four or more components that are attached to one another utilizing a high intensity welding procedure. In particular, the housing includes a circular hub portion cut or machined from a flat plate. Attached to the hub portion is an inner hollow cylinder that is preferably cut to length from available tube stock. A pair of circular flat plates are attached to, and extend radially away from, the inner hollow cylinder. Finally, an outer hollow cylinder, which is also preferably cut to length from available tube stock, is attached adjacent the outer edges of the circular flat plates to define a housing having a sealed annular chamber with a rectangular cross section. The multi-component structure allows for the use of a ring mass having a nearly rectangular cross section and the use of relatively thinner walled housing components.

Abstract: An interference suppressor comprises an amplitude limiter (2) to which a received signal is coupled. The limiter (2) is effective, when a dominant interfering signal (f1) is present together with a wanted signal (f1), to further increase the amplitude difference between interfering and wanted signals.A signal combiner (12) is fed with the received signal and also with a signal derived from the limiter (2) via a controlled attenuator (9) and which signal is arranged as to be in phase opposition to the received signal. A phase sensitive detector (8) is responsive to the output signal from the suppressor, which is provided by the signal combiner (12), and to the signal derived from the limiter (2) for providing a control signal for the attenuator (9). The control signal is effective to reduce the amplitude of the interfering signal present in the output signal.
