Abstract: A supersonic centrifugal compressor comprises a rotor located in a housing having a fluid intake eye. The fluid (air for instance) successively travels through an intake region wherein the rotor has a small number of blades which deflect the fluid tangentially by a small amount only, then through a compression region wherein the rotor has a higher number of blades producing tangential and meridian flow deflection. Last, the fluid flows substantially radially with respect to the rotor into a stationary diffuser.

Abstract: A device for monitoring the charging current for a storage battery of accumulators which will release an alarm when the charging current continues to increase during a set period of time, characterized in that the device contains a means of measuring the current through the storage battery and a further means of transforming the current to a voltage which is placed in a memory system at regular intervals by a switch responding to the recurrent signals from a timing device and is subjected to a comparison with the value of the voltage across the terminals to provide information displayed on a meter when the second value of the voltage exceeds the reference voltage at the instant when a signal is derived from a signal from the time device which signal slightly leads the recurring signals provided by the timing device for the control of the switch, the absence of this information at the instant of the derived signal providing via a logic gate, a signal to reset the meter to zero while the output from the meter provides a control signal for an alarm device.

Abstract: System for directing an aircraft along a glide path of variable angular direction. At a ground station, a generator of a radiofrequency carrier feeds an antenna radiating a lobe shaped directive pattern and the angular direction of the antenna lobe is scanned according to a cyclic reciprocating movement. The rate of variation of the lobe angular direction is linear in function of time and is equal for the two directions of the reciprocating scan movement. The carrier is modulated by a modulating signal whose frequency varies linearly and cyclically in function of time with a rate of variation equal to the rate of variation of the lobe angular direction and with a phase delay with respect to the lobe angular direction variation. Aboard the craft, the modulated carrier is demodulated and a circuit is provided for detecting the instants at which the frequency of the modulating signal is equal to a predetermined value. The sum of the amplitudes of the modulating signal at said instants represents the elevation of the glide path.

Abstract: The casing of a turboreactor is constituted of a refractory alloy based on nickel and includes an abradable porous metallic coating constituted by a nickel felt. The coating is bonded by brazing to the casing by applying the coating on the casing by a pressure ring with a larger coefficient of expansion and by effecting the brazing in a fluorinated-hydrogenated atmosphere at a temperature in the region of the fusion temperature of the solder. The assembly is then subjected to a chromization or chromaluminization treatment in a halogenated-hydrogenated atmosphere (free of fluorine) at a temperature of 800* to 1100*C.
