Abstract: This float comprises a fuselage (6) analogous to classic floats, but which here is topped by a leg (7) such that the fuselage (6) is completely submerged. This arrangement, combined with others that are secondary, makes it possible to reduce the vertical oscillations of the float produced by the sea swell while still ensuring good directional stability and satisfactory stability relative to other disturbances. Thus, a structure (1) suspended from the float (5) and which is part of a line (2, 3) towed by a ship remains at a constant depth. This invention can be applied, for example, to seismic tests at sea.

Abstract: An electronic relay including current sensors (11, 12, 13) mounted, between terminals (L1, T1, L2, T2, L31, T3), in series on alternating current power supply lines to a load (M). A back of a case (1) of the electronic relay includes a power card (C1) linked to the current sensors (11, 12, 13) and connected via connectors to electronic daughter cards (C2, C3, C4) carrying lateral terminal blocks (B1 and B2) which have outputs in the lateral openings of the case. A front of the case (1) includes a dialogue and communication card (C5) connected to at least one of the daughter cards (C3).

Abstract: A thermal relay is disclosed which can be remotely re-set and/or tripped by means of remote control electromagnets.The case of the relay has second fixing means adapted to receive first fixing means belonging to one and the same electromagnet can in which an extension of the core or plate is orientable so as to come opposite each of the re-setting and testing pushers placed on the front face of the relay.

Abstract: A device is provided for adjusting the relative position of two parts of the same piece by deforming an intermediate zone connecting these two parts together, by means of a conical screw, and having a tapped bore in which said screw may be screwed, and a cut out which extends from a first edge of the piece to said bore, wherein said intermediate zone further includes at least a second cut out opening into said bore, opposite said first cut out which defines with a second edge of the piece a deformable zone, forming a hinge, offset with respect to said bore.
