Abstract: The acceleration measurement system has a first thermal cell optimized in sensitivity and a second thermal cell optimized in passband, which cells are connected to inputs of a servo-control loop including an amplifier presenting gain that varies as a function of input signal frequency.

Abstract: The invention provides an apparatus for measuring microgravity acceleration that includes an elongate flow chamber having a first end and a second end and a liquid contained therein. Each end of the chamber is engaged by a plug member that is positioned to block the flow of the liquid through the ends of the container. Each plug member is maintained at a different known temperature such that a temperature gradient is created across the flow chamber. Temperature sensors are immersed in the liquid, the sensors being spaced apart along a line intersecting the axis of the flow chamber and normal thereto. Quasi-steady components of acceleration can be calculated based on the difference in the temperatures measured by the temperature sensors.

Abstract: The sealing strip has a main part (1') with a first sealing lip (6) for making sealing contact with a pane (7) or a filling element. The pane (7) is placed against the sealing lip (6) during assembly and rests on the top (10) of a lip (9'). A recess (13') is provided in a bridge (4') in the body of the sealing strip. The foot or base (16') is a second part (2'), which carries a second sealing lip (15') in contact with the other side of the pan (7'), fits into the recess. When the foot (16') is inserted into the recess (13'), the two sealing lips (6'15') are elastically deformed and pressed against the pane (7'). The inserted foot has a groove (19, 22) at one end in which a rib (14') engages. The foot (16') and hence the part ( 2') are thus firmly anchored in the main part (1').
