This socket, intended primarily to be mounted at the end of a mooring cable for an anchoring system of a mobile massive element, comprises a socket body 12 having an internal cavity 14 comprising a guide chamber 34 for the mooring cable 22, an intermediate section 18 and a fastening receptacle 20 intended to receive and block the ends of the strands of the mooring cable 22, and means 30, 30′ for coupling with the mobile massive element to be anchored, positioned on the socket body 12 so as to define a pivoting axis 32 of the socket body 12, which axis passes through the intermediate section 18. The use of the socket in anchoring systems, especially in the offshore environment, assures natural self-alignment thereof with the cable on which it is mounted, during the diverse movements by which the anchoring system is affected.

The present invention relates to a FINLINE type microwave band-pass filter comprising a waveguide provided with an insulating substrate placed in an E plane of the guide and comprising on at least one of the surfaces, conductive inserts electrically connected to the internal surfaces of the guide which support the substrate and which determine by their dimensions and their positioning on the substrate a Chebyshev type filter response curve. The filter includes at least one cavity in perpendicular short circuit to the substrate, the positioning and the dimensions of the cavity determining a transmission zero on the filter response curve for attenuating the frequencies situated around this zero. Such a filter is used in particular in transmission terminals operating in the Ka band.

The invention proposes a repeater designed for indoor transmissions. The useful frequency band is split into two frequency bands and the repeater amplifies the signals from one of the bands and translates them to the other band. The transposition of frequency bands results in preventing creating significant interference effects on the signal to be amplified. A management circuit is used to address, at lower cost, interference problems between the bands.

The invention relates to an electronic package comprising a substrate, a frequency tunable function at the surface of the said substrate, a dielectric material having variable permittivity with an electrical excitation in contact with the said function and a support secured to the substrate so as to define the package, characterized in that the substrate comprises a membrane, the said membrane lying between an upper cavity and a lower cavity of the package, at least one cavity being filled with the dielectric material that can be a liquid crystal. The presence of two cavities, at least one of which is filled with variable-permittivity dielectric material, makes it possible to increase the operating frequency range of the function.

The invention relates to a dual-band planar antenna formed by at least one slot of closed shape fabricated on a printed substrate having a perimeter equal to kλf, and two supply lines supplying power to the slot via two accesses separated by (2m+1)λf/4, where λf is the guided wavelength in the slot and k and m integers greater than 0, the slot comprising means modifying the operating frequency, one of the supply lines being situated on the said means. The invention is especially applicable to antennas used in domestic wireless networks (IEEE802-11a or Hyperlan 2 standards.
