The invention describes a process for extracting the ammonia nitrogen from liquid waste, comprising the following operating steps: a) placing the waste in contact with a basifying agent in a reactor; b) generating an ionized gaseous flow above the waste and in particular above the free surface of the waste and driving a gaseous current comprising ammonia outside the reactor; c) recovering the ammo...

A circuit architecture provides for the parallel supplying of power during electric or electromagnetic testing of electronic devices integrated on a same semiconductor wafer and bounded by scribe lines. The circuit architecture comprises a conductive grid interconnecting the electronic devices and having a portion external to the devices and a portion internal to the devices. The external portion ...

The invention concerns a device for the tightening of two elements (1, 2) one against the other, comprising a tie-rod (3) and a tightening lever (7) rotating about a pin (6). The tie-rod (3) is steadily anchored to a first element (1) and runs freely through the other element (2) anchoring itself on said pin (6). The end of lever (7) articulated on pin (6) is fork-shaped, the two arms whereof have...

A heat exchange assembly (5), in particular for removing heat from a primary cooling fluid of a nuclear reactor, includes a heat exchanger (10) immersed at least partially in a low-pressure primary fluid (F1) and having a plurality of pressurized tubes (12) in which a high-pressure secondary fluid (F2) circulates for removing heat from the primary fluid; and a passive safety device (20) for limiti...

The method involves supplying a rigid base element (5) to a thorn end (3a) of a thorn (3) in a thorn wheel (2). The rigid base element is held at the thorn end. A foil material (6) is folded around the thorn and the base element, such that a projection (6b) protrudes over the thorn end and the base element. The foil material wound around the thorn is longitudinally sealed with the thorn. The proje...

An apparatus (10) for trimming hooves in bovines or other farm animals, comprising at least two cages (11, 12) for containment, restraint and movement for a bovine or other animal, and means for the support and movement of the at least two cages (11, 12) from an inactive configuration on a vehicle (13) for the transport of the apparatus to an active configuration.

An orthopaedic support structure (10) that is adapted to support a user in a predetermined posture comprises an array of mobile elements (20), each of them having a support end point (21), that are arranged in such a way that the support end points (21) cooperate to define a support surface (22), The structure comprises, furthermore, a damping means (31) of the mobile elements (20) such that the s...
