Abstract: The device serves to interconnect first and second sections of a data bus in order to provide a transparent bi-directional data transmission along the bus comprised of the two sections, irrespective of the protocol used. Basically, the device includes a first transmitter-receiver module at which terminates a first bus section, and a second transmitter-receiver module at which terminates a second bus section. Both modules are disposed face-to-face without contact and are electromagnetically coupled. Each receiver module has a circuit for supplying a transmitting coil with a signal modulated by the data to be transmitted and coming from the bus section to which the module is connected, and a detector circuit for receiving a modulated signal from the same coil to produce the data to be transmitted to the bus section to which the module is connected.

Abstract: A movably mounted element (1) is stabilized with respect to a desired path according to one component of movement. The element is mounted with complete freedom of movement along that component of movement which takes part in the formation of the actual path and to maintain or return the movable member (1) to the predetermined path, for example, maintaining a spray manifold parallel to the ground. With the aid of a jack (10) there is exerted, between the movable member and its support point or points (3) and as a function of the position of the movable member with respect to the desired path, one or more forces whose magnitude is independent of the position of the movable member with respect to the points of support. The invention is applicable to movable members having plural degrees of movement in rotation and/or translation and particularly for the stabilization of a spray manifold.
