Title: Arrangement for adjusting the rotation speed of a single-phase or multi-phase induction machine
Inventor: SCHOERNER JOCHEN DR ING
IPC: H02P27/02
Filed: 1986-08-08
Abstract: The invention relates to an arrangement for adjusting the rotation speed of a single-phase or multi-phase induction machine having a multi-phase semiconductor three-phase controller, the switching pulses of the semiconductors of the three-phase controller being produced such that, by alternately and respectively switching through a selectable number of successive positive voltage half cycles and successive negative voltage half cycles in each phase, the output voltages of the three-phase controller form a multi-phase rotating-vector voltage system whose first harmonic is at a lower frequency than the frequency of the supplying network, said lower frequency corresponding to the selected number of successive voltage half cycles of one polarity or the other. In order to improve such arrangements such that currents and voltages supplied by them have a lower harmonic content, the windings of the induction machine are connected to freewheeling semiconductor arrangements in such a manner that the current ripple on the respective low-frequency half oscillation is reduced as a result of their freewheeling, which takes place by means of an associated semiconductor in the three-phase controller, in time with the individual half cycles being switched through.

Title: Wet ash remover
Inventor: TIMPER MANFRED
IPC: F23J1/02
Filed: 1988-03-18
Abstract: In known wet ash removers, lamellar separators are arranged in the trough. The solids separated on the lamellae slide counter to the flow entering the lamellar separator downwards into the trough and the danger exists that they are carried back into the lamellar separator. The new wet ash remover is intended to avoid these disadvantages. The overflow (9) supplies the overflow water in cross-flow to one end of the lamellar separator (10) arranged outside the trough (2), and the lamellar separator (10) has below the the lamellae (11) a suspended-matter collecting space (12c; 12d), from which the separated suspended matter can be guided back into the trough (2) with incoming water (12e).

Title: Adaptive control device for the air/fuel ratio for an internal combustion engine
Inventor: MANAKA TOSHIO
IPC: F02D41/04
Filed: 1989-01-16
Abstract: A percentage of injected fuel adhering to a surrounding section of an intake valve is determined in accordance with a fluctuating value of an air/fuel ratio correction coefficient and with a fluctuating value of an output signal of an air/fuel ratio detector or an oxygen-quantity sensor. Each percentage of injected fuel adhering is divided up and each value stored in a sub-region of a characteristic memory map of a control unit. The percentage of injected fuel adhering is stored in a memory of the control unit and determined from the characteristic memory map in accordance with the instantaneous throttle-valve opening angle and the instantaneous temperature of the engine cooling water. The main percentage of the injected fuel is obtained by means of a learning control process in the control unit. An air/fuel ratio correction in a transition period is thus carried out with continuous variation.
