Filed: 1987-07-06
Abstract: An hydraulic control system, for example for use 
in moving control surfaces of aircraft, comprises first 
and second actuators (12A, 12B) operating in tandem.

Title: Improvements in computer graphics systems
IPC: G06T11/00
Filed: 1988-02-29
Abstract: A multi-tasking, multiple windowing computer graphics facility which does not place undue burdens upon the processing power of its host computer comprises a multi-planar memory to which data defining windows to be displayed in viewports on a display screen can be written, and a plurality of viewport controllers each individually associated with a respective one of the memory planes and capable of extracting data from each of a plurality of windows defined in its respective memory plane for effecting a corresponding display in any desired viewport location on the display screen. For the management of overlapping viewports, the window-viewport assignments which determine the display locations of viewports on the display screen include viewport priority indications which are taken into account in the reading out of data from the several planes of the multi-planar memory so that overlapping viewports are handled automatically and can appear transparent or opaque relative to one another as required. Windows can be created of any size and any number of planes deep (up to the available depth of the display memory), and opaque or transparent images can be moved freely around the display screen without requiring modification of the data in the memory by flexibly mapping windows in the display memory to viewports on the screen. A VRAM (video RAM) multi-planar memory is used and the viewport controllers are configured as modular VLSI components which can be cascaded for addressing any number of memory planes.

Title: Quartz tuning fork manometer
IPC: G01L21/22
Filed: 1989-12-08
Abstract: In the present pressure measurement process the damping signal of a tuning fork quartz manometer, which is a measure of the prevailing pressure, is so combined with the correction value proportional to the resonant frequency that a measurement result is obtained, which is independent of any contamination of the tuning fork quartz. Apart from the resonant frequency (fR) of the measuring quartz (11), preferably also the resonant frequency (fR') of a reference quartz (21) kept at constant pressure is determined. Thus, the damping signal (RS) can be corrected by a correction value proportional to the difference between the two reference frequencies (RR'-fR), which is substantially temperature-independent.
