Abstract: A turret comprising a rotating joint and an angular velocity reduction device is disclosed. A tracking turret comprises an angular velocity reduction device with an elliptical wave generator, an externally-toothed flexible ring and an internally-toothed rigid ring, and a rotating joint used for the transmission of electrical signals. The invention can be applied chiefly to the making of close-range anti-aircraft defense turrets.

Abstract: An automatic interconnection assembly with: on one side, a first connector element, and on the opposite side, a telescopic assembly having at its free end a second connector element. This assembly is moved by a control actuator, the extension of which makes the second connector element approach and then plug into the first connector element. Means axially and transversally align the two connector elements and orients them angularly with respect to each other, prior to the plug-in operation, as they approach each other.

Abstract: A pivoting joint connects two rectangular waveguides, connecting transmission-reception equipment on board a satellite to an antenna, which is only opened out when the satellite has been placed in orbit. These waveguides comprise a fixed section and a moving section, pivoting about the longitudinal axis common to the two sections. They issue or open out in facing manner on two parallel planar faces separated by a non-zero distance, but which is very small compared with the wavelength. One of these faces has a quarter-wave trap ensuring the radio seal of the joint. An abutment defines the position in which the two guides are in an extension of one another. When the satellite reaches orbit, antenna is opened out and the joint pivots to this position.
