Title: Arrangement having a plurality of display device controllers
Inventor: RHEIN BERND DIPL ING
IPC: G09G5/12
Filed: 1988-11-11
Abstract: In process control engineering a plurality of display device controllers (ST1, ST2) having visual display units (SG1, SG2) are used in operation and monitoring control rooms or process control systems, on the screens (BS1, BS2) of which visual display units pixels flash in a clock-controlled manner in various frequencies and colours. To avoid asynchronous flashing of the pixels represented on the various screens (BS1, BS2), which flash at the same frequency, the display device controllers (ST1, ST2) are in each case provided with a sequence control system (AS1, AS2) which generate in a first operating mode a first clock (Tae) for controlling the flashing of the pixels and a second clock (Tye) for synchronising the flashing and switch to a synchronisation bus (SYB) and are controlled in a second operating mode in such a manner that they receive the first and the second clock signal (Tae, Tye) from the synchronisation bus (SYB) and thus control the flashing of pixels on the screen (BS1, BS2) of the visual display unit (SG1, SG2) assigned to them in each case, in each case one display device controller (ST1, ST2) functioning in the first operating mode and the others being in the second operating mode. The invention is used in particular in colour graphics visual display units. <IMAGE>

Title: Labelling machine for vessels with a variable programme of rotation for the vessel
Inventor: ZODROW RUDOLF
IPC: B65C9/04
Filed: 1988-11-29
Abstract: The invention relates to a labelling machine for vessels 2, in which the vessels 2 are labelled especially with all-round labels. The labelling machine has a turntable 4 with rotary plates 3, mounted on it, for the vessels 2 to be labelled, and at least one labelling station 5 arranged stationarily on the circumference of the turntable 4. The drive of the rotary plates 3 takes place via engagement members 10 which sense a control cam 8. The control cam 8 is designed in portions P1 to P3, not directly succeeding one another, for different programmes of rotation, by means of which vessels of different sizes must be rotated at the labelling station 5 for a fault-free transfer of the labels. Located in the regions between these portions P1 to P3 are portions which are designed for a constant rotational speed, especially 0. To obtain a specific programme of rotation at the stationary labelling station, the carrier of the control cam 8 is mounted rotatably in the turntable frame. The arrangement is such that any two of the portions designed for a constant rotational speed are located at the vessel entry and vessel exit. <IMAGE>

Patent DE-3933471-A1 (DE)
Inventor: ALLENBERG BERND
IPC: G05B13/04
Filed: 1989-10-06
Abstract: In a process and an apparatus for improving the metering accuracy of a differential metering balance connected to a controller and to an estimator, there is an evaluation device which minimises at least two stochastic disturbance variables by means of a model computation. For this, the evaluation device contains an analyser circuit which scans an estimated-value signal for a specific period of time and which forms the power-density spectrum of this. Those frequencies which exceed the value of an especially high power density are determined from the power-density spectrum in an identifying circuit. These frequencies serve, in a correcting circuit to form a frequency spectrum which corresponds to the actual stochastic disturbances. In a comparator circuit, this spectrum is compared with a model spectrum calculated by a model-computing circuit, and that model coming nearest to the actual spectrum is determined. A controller-setting circuit then determines from the model spectrum obtained the spectrum which corresponds to that of the pick-up disturbances and of the bulk-density disturbances. The controller-setting circuit forms from this a signal which serves for optimising the controller.
