The invention relates to a cooling system, with a cooler (1) taking up heat, for a permanently-energized synchronous motor, in particular, a motor for a locomotive. A first line (2) leads from the output of the cooler (1) to the input of a recirculation cooler (4), emitting heat to the environment. A second line (5) leads from the output of the recirculation cooler (4) to the input of the cooler (1). A first non-return valve (3), permitting flow towards the recirculation cooler (4), is arranged in the first line (2) and a second non-return valve (7), permitting flow towards the cooler (1), is arranged in the second line (5).

The present invention relates to a unit and a device, comprising a first rigid arm (102,202,32), having a first (110,210) and a second end, a connecting unit (106,206,36), having at least two rigid parts, one of which is fitted with a first connection site (112,212), and another with a second connection site (114,214), wherein at least two of said parts are rotatably mounted, in relation to one another, around an axis of rotation through said connection unit, wherein the first end (110, 210) of the first arm (102,202,32) is connected to the first connection site (112,212) of the connection unit (106,206,36), and wherein the first arm (102,202,32) includes an outer conductor and an inner conductor (120), coaxially arranged and electrically insulated in relation to one another, for enabling transfer of radiofrequency signals between the first rigid arm (102,202,32) and the second connection site (114,214) of the rotatable connection unit (106,206,36).

A frame structure consisting of two compound units provided with mutually facing grooves undercut on either side, in which the first compound unit can be attached in a desired position to the second compound unit via a detachable coupling which comprises a turning part which can be turned from the outside manually via a handle about its longitudinal axis by about 90 DEG into its coupling or decoupling position, and which in its coupling position positively engages by means of a T-head at its one end in one of the two grooves and by means of anchoring means at its other end in the other of the two grooves and can be locked in this coupling position by means of an anti-rotation device. To connect the two compound units to each other without special tools, but above all to be able also to detach them from each other again, it is proposed according to the invention that the anchoring means comprise a punched part which is arranged longitudinally displaceably in the one groove and bears the turning part which is freely rotatable relative to it and that the handle comprise a resilient element connected securely against rotation to the turning part, which element in decoupling position extends in relieved state or under only slight stress between the two compound units and in coupling position engages under bending stress behind a holder.

The present invention relates to a fluid separation device (10) for separating fluid, oil and oil spray from a gas. This fluid separation device (10) comprises a base carrier (21) in which fluid separator elements (20) in the form of flow-through tubes with worm-like segments (23) arranged therein, are integrated. The worm-like segments (23) at the same time form spiral flow paths (25) for the gas. They have a maximal length of half a pitch of the worm-like segment (23) so that the base carrier (21) together with the associated fluid separator elements (20) may be formed as one piece. Several base carriers may be arranged one after the other in a manner such that individual fluid separator elements of various base carriers form a common flow path for the gas.

This invention relates to a module for the wall-mounting of a terminal (13) of an air conditioning system which has the characteristic of comprising a structure (4, 25) which can be embedded into a wall (1) forming a space (2). The structure (4, 25) removably houses the terminal (13) in such a way as to form the said space (2) in accordance with good practice and such as to ensure a correct surface finish in the vicinity of the perimetral edge (2A) of the said space (2).

The invention relates to a heat exchanger for motorized vehicles, comprising: at least one heat-conducting conduit for passage of a first medium, a covering of a thermally conducting porous structure connected to an external side of the conduit for passage of a second medium surrounding the conduit.

The invention relates to a cooling device ( 1 ) for cooling an item to be cooled, especially for use in the examination, handling and processing of cryogenic samples. The device includes a cooling compartment ( 3 ) for receiving the item to be cooled, an inner wall defining the cooling compartment ( 3 ), an outer wall, a space between the outer wall and the inner wall, and a coolant feed line ( 11 ) for feeding a coolant. According to the invention, the coolant feed line ( 11 ) leads into the space between the inner wall and the outer wall and feeds the coolant into the space, the inner wall being permeable for the coolant.

The present invention relates to a container (1) for a liquid or viscous product, comprising a sub
