Title: Operating IC engine from no=load to loaded state - by taking into account air throughput reference valves dependent on engine state
Inventor: FRIESE MANFRED
IPC: F02D31/00
Filed: 1989-07-29
Abstract: At levels of higher angular speeds, air flow is regulated via a bypass (6), taking into account reference values for air throughput-dependent on operating parameters (n.T) of the engine (1). The air throughput regulation is achieved using a setting member (4). A one-sided air throughput control takes place in the sense that only for falling below the reference value of the air throughput does control take place.  Account is taken of the reference value of the air throughput dependent on the angular speed (n) and/or the temp. (T) of the engine. USE/ADVANTAGE - Improved transition from no-load to load and vice versa.  Not critical as regards tolerances of setting member.

Patent DE-3935564-A1 (DE)
Inventor: TOMINAGA FUKUTOSHI
IPC: G05F1/59
Filed: 1989-10-25
Abstract: When the mains A.C. supply is normal, each UPS has its AC input switch 23, inverter output switch 24 and paralleling switch 25 all closed, an oscillator 29 operates in synchronism with mains zero crossings and drives inverter 26 via phase shifter 30 controlled so that inverter 26 operates on standby delivering no load current. On mains failure or restoration, all UPS's switch between standby and operation mode together. In the operation mode, oscillators 29 are synchronised by circuit 41 and the delays of phase shifter 30 are nullified. The leakage inductance, due to shunts 22d, e, of each UPS is inversely proportional to its output capacity whereby load current allocation between UPS's is proportional to their output capacities without requiring special control means. If an AC input monitor circuit 34 of one UPS fails, a monitor circuit 38 with majority volting logic, (Fig 3) opens switch 25 of that UPS. Both switch 25 and also switch 24 are opened if a monitor 32 senses an abnormality in inverter 26. Switch 25 is also opened if a monitor 43 senses that oscillator 29 is out of phase with oscillators 29 of the other UPS's.   In a three phase triport UPS, the transformer cores may be arranged as a triangular prism with common windings on paired legs of adjacent cores (Fig 7). <IMAGE>
Patent DE-3936787-A1 (DE)
Inventor: GLEIM GUENTER DIPL ING
IPC: H04N17/04
Filed: 1989-11-04
Abstract: A device is useful for correcting the grid in a TV set. In known grid-correction devices, in particular for correcting the convergence, correction values for certain pixels determined by points of intersection (K) of a grid pattern are stored in memories. In devices with several operating modes with different deflection amplitudes, fresh correction values must be stored for each operating mode, because the points of intersection shift on the picture area. In order to reduce the number of memories in operating modes with different deflection amplitudes, the instantaneous position of the control pulses for the grid pattern is varied so that the points of intersection (K) are always located at the same spatial positions of the picture area (1). The device is particularly useful for correcting the convergence in projection TV sets.
