Abstract: The invention relates to a method for the treatment of water contaminated by thermal oil and collection of said oil (for example, a eutectic mixture of biphenyl and diphenyl oxide), formed by a cooling phase (2) for cooling (to a temperature between the freezing point of the thermal oil and that of water) the mixture (1) of water and thermal oil, followed by the collection (3) of the part (4) of frozen thermal oil (precipitated or in suspension) by means of mechanical filtering. The remainder of contaminated water is treated in absorption filters and in activated carbon adsorption filters. The equipment required to implement this method comprises a cooling unit, a unit for the separation of phases by means of mechanical filtering for the collection (3) of the frozen thermal oil part (4), a unit (6) of absorption filters and a unit (7) of adsorption filters (activated carbon unit).

Abstract: A folding structure (2), is provided to which one or more rollers (3) are coupled, which is constituted by an articulated one-piece construction, formed of straight sections (2a, 2b) joined together with articulated joints that rotate around a vertical axis (4) and movement of the sections on the horizontal plane, and hinged joints that rotate around a horizontal axis (5) and movement of the sections on the vertical plane. In a use position, it has a rectangular frame shape, while in a folded position it forms an elongated and flat compact block. The upper part of the structure (2) has recesses (8) with protruding nipples (9), suitable for being inserted into holes (10) made on the ends (3a) of the roller (3) axis; while dampers (11) are disposed in the lower part. There is a joint that rotates around a vertical axis (4), and another hinged joint that rotates around a horizontal axis (5).

Abstract: It consists of a folding structure (2), to which one or more rollers (3) are coupled, which is constituted by an articulated one-piece construction, formed of a plurality of straight sections (2a, 2b) joined together by means of articulated joints that rotate around a vertical axis (4) and movement of the sections on the horizontal plane, and hinged joints that rotate around a horizontal axis (5) and movement of the sections on the vertical plane. In its use position, it has a rectangular frame shape, while in its folded position it forms an elongated and flat compact block. The upper part of the structure (2) has recesses (8) with protruding nipples (9), suitable for being inserted into holes (10) made on the ends (3a) of the roller (3) axis; while dampers (11) made of anti-slip material are disposed in the lower part thereof.

Abstract: A transportation tooling of the type that borders the blade at its root and at an intermediate point. This tooling is used in combination with platforms placed on the transportation elements and the platforms can move transversely and turn or rotate with respect to the devices of transportation without affecting blade integrity. Also a method for blade transportation with the tip of one blade facing the tip of the adjacent blade so as to use the minimum space on the devices of transportation. The rail tooling takes into account the maximum corner radius that the train will encounter while absorbing the bending and torsion stress acting on the blades.

Abstract: The invention relates to a total power regulation device for two pumps (2, 42), each of which is connected to a working conduit (5, 45). The delivery volume of the pumps (2, 42) can be set separately by a respective adjusting device (6, 46), whereby a control pressure that is active in each adjusting device (6, 46) can be set by a total power regulation valve (18, 58). The latter (18, 58) has a measuring surface (24, 64) of the total power regulation valve (18, 58) of one pump (2, 42) can be directly exposed to the working pressure of the other pump (42, 2).

Abstract: The invention relates to a hydrostatic drive comprising at least one hydraulic pump (1) and a first and a second hydraulic motor (6, 25), which are respectively connected to said hydraulic pump (1) by means of two service lines (4, 41, 5, 5?) and whose absorption volume can be regulated by means of a regulator (40, 41). One respective hydraulic motor (6, 25) for a drive train is provided per respective right or left vehicle side. The regulators (40, 41) are actuated by a respective regulator piston (7, 26). The regulator pistons (7, 26) of both hydraulic motors (6, 25) can be subjected to a force by means of a common high pressure, which equals the highest pressure that prevails in the service lines (4, 41, 5, 5?) of both hydraulic motors (6, 25). Each force is opposed to a respective counter-force, which is generated by a control pressure in a control pressure chamber (11, 11?).

Abstract: The invention relates to an axial piston motor constructed as a swivel-slide structure with a channel to feed cleaning fluid to the driving shaft bearings. The axial piston motor (1) comprises a swivelling cylinder drum (8) and a driving shaft (3) supported on driving shaft bearings (4, 5).

In addition, the invention provides for a control specular element (18) with reniform control elements and a regulating device (26), by which the cylinder drum (8) together with the control specular element (18) can be swivelled. According to the improvement added by the invention, the cleaning fluid channel is taken through the setting journal (25) and control specular element (18) up to the central journal (16).
