摘要： The present invention relates to a transposition device for a prefabricated electrical canalization, said canalization comprising a certain number of conducting bars distributing different phases including or not the neutral, said bars extending substantially parallel to one another, said transposition device being designed to reverse the position of at least two bars with respect to one another in the canalization. This device is characterized in that it is designed to be incorporated in said canalization, and comprises the same number of portions of bar as the number of above-mentioned bars of the canalization, at least one of these portions of bar being interrupted inside the device so as to form two parts of portions of bars, these parts comprising at their ends a fold towards the outside of said device thus forming an end part that is outwardly offset so as to increase the space between these end parts, this space enabling electrical connection of said end parts of portions of bars with one another by means of a conducting bridge fixed onto said end parts and electrically connecting said end parts via the outside of the set of portions of bars on one side or the other of the device in such a way that the two above-mentioned parts of portions of bar present a different position on input and output of the transposition device.

摘要： A device for measuring the power in a microwave transmission and for providing a measuring port at the output of a microwave signal generator or transmitter. First and second quarter wavelength transmission line sections, coupled in series with one another and having characteristic impedances Z.sub.2 and Z.sub.1 respectively, where Z.sub.2 >>Z.sub.1, are coupled at the first section to a predetermined point on a transmission line to be monitored. A port at the free end of the second section allows for the connection of two independent measuring circuits to the transmission line.

摘要： A drag damper for use on a rotary wing aircraft rotor comprises a body defining two variable volume chambers linked by a piston. The chambers are filled with fluid and are connected by a restriction port (35) and by a channel (32) of larger cross-section than the restriction port. A secondary piston slidable and pressure-tight piston is fitted in the channel and loaded by an elastic bias (34). The equivalent mass of this secondary piston (33) and of the fluid which it displaces, and the stiffness of the elastic bias (34) are such that the secondary piston is resonant in the channel (32) at the rotation frequency of the rotor, to filter the dynamic component at this frequency of stresses applied to the damper (20). Furthermore at the natural drag frequency of the corresponding blade, the elastic bias substantially blocks the secondary piston (33) in its channel (32), and the flow of fluid between the chambers (29, 30) of the damper (20) takes place mainly via the restriction port (35) calibrated to provide substantial damping at this frequency.

摘要： Mechanical assembly for transmitting forces along an axis driven by a substantially axial movement in translation under the effect of a thrust load. This mechanical assembly comprises a transmitting part of the thrust load input movement and a receiving part of the thrust load output movement, said mechanical assembly comprising a detector for detecting the passing of a force threshold represented by a predetermined value of the thrust load, and including an elastic element and an indicator part arranged in such a way that when the thrust load exceeds the threshold value, the thrust load acts on the elastic element and modifies its axial dimension allowing the indicator part to move to the warning position.
