Abstract: A mounting system of a pneumatic module and of an electrical module, in a coupler head of a wagon or coach of a goods railway vehicle wherein both the module integrating the pneumatic connection, with the isolation or shut-off valve thereof, and the module corresponding to the electrical and data connection, are incorporated into a carriage coupled to the coupler head such that this carriage can perform a guided approach or connection movement by means of the action of an elastic means.

Abstract: Manipulator for an ultra-high vacuum chamber comprising an annular proximal base (1a) that can be securely anchored around an access opening (2a) of a tank (2) of the ultra-high vacuum chamber, a distal base (1b) connected to the proximal base (1a) by means of a bellows element (3) with an inner space (3a) in communication with the ultra-high vacuum chamber through an access opening (2a), a sample-carrying column (4) attached to the distal base (1b), that passes through the inner space (3a) to enter into the ultra-high-vacuum chamber, and a movement system for moving the distal base (1b) in relation to the proximal base, wherein the movement system comprises six actuators (5) each one actuated by respective electric motors (6) radially arranged around the bellows element (3) and connected to the proximal base (1a) in an articulated manner by means of respective proximal ball joints (7) and connected to the distal base (1b) in an articulated manner by means of respective distal ball joints (8), and the bellows
