Abstract: Method for determining the composition of a homogeneous fluid, for example a petroleum effluent on flow, an emulsion consisting of water and oil, or a foam consisting of oil and gas.The attenuation and the phase shift of microwave beams that have traversed a fluid of unknown composition with paths of different lengths are measured (stage A). Two equations approaching the measured values are determined, the first equation giving a relation between the attenuation and the length of the path, the second equation giving a relation between the phase shift and the length of the path (stage C). Then the composition of the fluid is determined by comparing the two equations with pairs of equations stored in form of databases, each pair of equations corresponding to a fluid of known composition (stage D).

Abstract: Very low distortion hydrophone comprising at least one pair of sensitive elements (6 and 8) of piezoelectric type (for example and not limitatively), associated with at least one of the opposite flexible faces of a housing (1) formed by assembling cups (2 and 3) with rigid edges. The opposite faces of one of the discs, (6), are provided with electrodes over the total surface thereof. On the other hand, at least one of electrodes (9a and 9b) associated with the opposite faces of second disc (8) only covers one or more portions (an annular strip for example) of each of these faces in an external zone of each cup (2, 3) more subjected to nonlinear stresses. Electrodes (7 and 9) of the two sensitive discs (6 and 8) are interconnected so as to make the difference between the electric signals generated by the two discs in response to the pressures applied, with the effect, experimentally verified, that the distortion resulting from this layout, notably due to a second harmonic (2), is practically suppressed. The hydrophone can be used for geophysics, detection or locating, etc.

Abstract: In order to restore a clock signal that has been used for coding digitized signals transmitted on a transmission channel, such as a line, the case when the received signals are distorted, the times (ti) when the signals go through their maxima (M) are detected with precision through an analysis of a series of samples (Ep) taken from the signals received during a time "window" (W) positioned with reference to a local clock. A device determines the amplitude differences between the successive samples and compares the difference configuration as obtained with predetermined standard configurations representative of forms that are acceptable for the maxima. In case when the difference configuration corresponds to no recognized standard configuration, the frequency of the local clock is changed so as to re-establish a sufficient similarity with a standard configuration.

Abstract: In a pipe containing a fluid wherein particles circulate, at least one detector is attached. The detector includes a cavity in fluid communication with the pipe by a vent whose section, at least at an opening for fluid communication with a pipe is of the same dimensions as that of the circulating particles. A periodic exciter such as a source of acoustical waves or a generator of the periodic motion piston type suitable for inducing alternate pressure variations in the fluid in the cavity is coupled with the cavity. The excitation frequency can be selected in keeping with a resonance frequency of the cavity. Signals representative of the pressure variations of the excited fluid, resulting from flowing of the particles past the opening of each vent are measured. Processing of the signals allows the velocity of the particles to be determined. Other parameters of the particles can be determined by means of two distinct detectors coupled with the pipe. The detector may be used for monitoring the flow of catalytic particles in continuous reforming plants, for example.

Abstract: Modular device for the reception, the acquisition and the transmission, to a central control and recording unit, of signals picked up by a very large number of seismic acoustic receivers distributed along a streamer of great length under water in operation.The receivers in each one of the sections (Tk) of the streamer are arranged in several groups and the receivers (H1 to Hp) of a same group are connected with an acquisition unit (U1 to Um) located close to them. All the units of each section are connected through digitized command and data transmission lines (LOC,BD) with a common memory and a transmission management unit in an interconnection box (Bk) at one end of the streamer section. Transferring a great part of the electronic equipment into the streamer sections is very favorable for the balancing of the streamer in the water, for obtaining a good signal to noise ratio and it facilitates the development and the exploitation of the material.

Abstract: A method and device for acquiring signals by amplifying, sampling and digitizing for permanently controlling the stability of the gain at each successive sampling cycle carried out on the signals as disclosed. A first digitizing of a non amplified signal sample and at least a second digitizing of an amplified signal sample is performed at each cycle. Each gain is measured by establishing a ratio between the values respectively obtained at the end of each second digitizing and of the first digitizing, and the amplifier gain is corrected if the gain of each gain actually applied to the acquired signal has deviated from a nominal value. The invention has an application to the digitizing of seismic signals.
