Title: Balancing dynamic alternating forces of rotor systems - using axle deflection sensors and controlling positioned of small weights
IPC: G01M1/36
Filed: 1990-07-31
Abstract: Compensating variable alternating forces in rotation systems with a wt. on a rotation axle involves correcting for deflections of the rotation axle using a control loop. The deflection sensors are mounted on the axle. The compensating forces are generated outside the axle and transferred to it. The control force transferred to a translational force transfer system (6) on the axle (1) is conveyed from there to the region of the wt. (10) on the axle. The force moves small weights (7) radially to vary the centrifugal force, thus compensating the original alternating force. USE/ADVANTAGE - Esp. for helicopter and wind vane rotors. Reduction of radial variable forces during operation, made possible.

Patent DE-4109433-A1 (DE)
Inventor: PFALZGRAF BERNHARD DIPL ING
IPC: F02P5/15
Filed: 1991-03-22
Abstract: The invention concerns pinking control in a spark-ignition internal combustion engine with a short-time control and an additional long-time control. The long-time adaptation consists of a first correction measure, in which an adaptation value for a given operating point just passed is measured in function of control strokes, and the predetermined characteristic field value is referred to new predetermined spark timing values (predetermined characteristic field value plus adaptation value) when pinking occurs. The long-time adaptation also includes a second correction measure, whereby when a large, recognized and necessary change occurs in an adaptation value (LZ) for one operating point, the adaptation values (LZ) for the other correction characteristic field points are also changed by adding correction values (LN values). When operating points are changed, the pinking regulation as a whole therefore becomes more stable and the amount of pinking is reduced.
