Title: Gearing for sectional or roller shutter doors
IPC: E05F15/668
Filed: 1988-07-22
Abstract: The invention relates to a gearing for shutter doors which can move up and down, for example spring-compensated sectional or roller shutter doors, having a motor-driven gearing stage, with a driven shaft which can be connected in a frictionally locking manner to a shutter-door shaft or optionally forms the shutter-door shaft. Provided for an emergency actuation by hand is a second gearing stage which is designed for hand operation of the driven shaft and has a considerably smaller transmission ratio than the first gearing stage. The gearing may, if appropriate, exhibit a mechanical braking device which acts directly on the driven shaft, with the result that, even if the gearing breaks, the shutter door is secured against a downwards movement.

Title: Measuring contents of motor vehicle fuel tank - using pressure sensor for gas vol. above fuel level and evaluator
Inventor: WILDE HANS PROF DR
IPC: G01F17/00
Filed: 1989-09-06
Abstract: The gas vol. (3), esp. of air, above the fuel (2) level is dependent upon the amt. of fuel in the tanks (1). The gas pressure of the vol. is changed at timed intervals between given lower and higher pressure vlaues by pu,ping in and releasing a gas. The time needed for change of pressure is measured.  From this measured time the gas. vol. is determined and, taking into account the total vol. of the tank, the fuel content is derived. After attaining the higher pressure value through pumping in a gas, the time taken to reach the lower value by releasing the gas is measured, this time being below approx.  two seconds. The gas pressure is pref. measured by a pizeo-electric sensor. The latter (4) is connected to a microcomputer (12) and an electronic evaluating unit (15) with a display instrument (16). ADVANTAGE - Simply avoids influence to temp on measurement.
