Patent DE-19611068-A1 (DE)
Title: Moulding material vol. control equipment e.g. for moulds in concrete block machine
Inventor: BALD HUBERT DIPL ING
IPC: B30B11/00
Filed: 1996-03-21
Abstract: The volume control equipment involves the measurement of the sideways movement of the compacting thrust applied to the concrete, and analysing it with regard to typical values. A comparison with stored standard values is made in order to provide a value for the volume or the compaction quality. The blocks are arranged in their moulds within the forming and compacting area during the control procedure. The motional characteristics of the moulding die, or of items connected to it, are measured to provide an indirect indication of the volume or quality of compaction. The physical quantities measured are converted to electrical or optical values for processing.

Title: Control of transformer in converter or inverter
Inventor: ERHARTT LUTZ DIPL ING
IPC: H02M3/337
Filed: 1996-08-28
Abstract: In a procedure for controlling a transformer in a PWM half- or full- bridge converter or inverter where either a primary winding of the transformer or the voltage supply to it is periodically reversed and the duration of any such connection is dependent of the required magnitude of the output voltage at the transformer secondary, the duration of a pulse generated directly for a required change in output voltage is only determined thereby corresponding to a portion of the required voltage change.  In particular, it corresponds to the average of the actual required magnitude and the previous required magnitude, not only for increase but also for decrease in output voltage.

Patent DE-19720433-A1 (DE)
Title: Oscillation and noise damping apparatus for vehicle
Inventor: AOKI KAZUSHIGE
IPC: G05B21/02
Filed: 1997-05-15
Abstract: The apparatus includes a first source which generates a periodic wave and a second source which generates a control wave. The control wave is superimposed with the periodic wave. A reference signal (Rx) is generated which represents a developed condition of the periodic wave. A residual wave is detected which is the wave after superimposing the control wave with the periodic wave. A residual wave signal (e) which represents the residual wave is output by a residual wave detector.  A control unit (25) which includes an adaptive digital filter, filters the reference signal and generates a drive signal (y) for the second source. An adaptive algorithm updates the filter coefficients on the basis of either the reference signal or the residual wave signal to control the damping of the periodic wave. A divergence identification apparatus determines whether a divergence of higher order exists when damping the periodic wave on the basis of the sum of two sampled values of either the drive signal or the residual wave signal.
