Abstract: An apparatus for monitoring particulate matter in the fluid comprises a filter means (28) through which fluid is arranged to flow. A pressure sensing means (46) senses the fluid pressure difference across the filter means and produces a pressure signal indicative of the magnitude of the pressure difference. A processing means (49) receives the pressure signal and evaluates therefrom the rate of change of the magnitude of the pressure difference in order to give an indication of particulate matter levels in the fluid. In this way on line monitoring of the debris generation in, for example a oil system, can be effected so that abnormal increases in debris can be detected and long term trends in the build-up of debris can be observed. 
     A particular form of filter medium is also disclosed wherein the filter mean can be transported so that a filter record can be maintained and systematic X-ray analysis of the fitter record can be effected.

Abstract: The system makes it possible, by a simple and rapid procedure, to determine the aiming angles (ES, EG), without moving the barrel or calculating the lateral speed of the target. When the firing cross-hairs (R) representing the axis (DP) of the barrel have been aligned with the target (B), the operator triggers a measuring sequence by pressing a button (20D or 20G) corresponding to the right or left direction of the lateral movement of the target. The cross-hairs observed on the screen of a monitor (6) are then controlled by the programming of a management and computation unit (10) which generates an instantaneous deviation in relation to the observed target and an automatic return at constant speed. The operator releases the button when there is coincidence. The duration of this sequence, that of the flight time of the projectile, and the angular aiming angle covered in terms of relative bearing during this sequence make it possible to calculate the aiming value in terms of relative bearing for firing, the elevation being calculated as a function of the distance, ballistic data and type of ammunition. <IMAGE>
