Abstract: The invention relates to an operating unit for nautical use, wherein an internal combustion engine drives an electric energy generator. According to the invention, the generator is cooled by oil in which the rotor and the stator are partly immersed: the spinning motion of the rotor drags the oil into the air gap, thus cooling the stator as well.

Abstract: The invention relates to a finkeel (2) for boats, having of a fixed part (3) attached to the hull (1) and a movable part comprising two leeboards (4, 5) that can be orientated in an independent manner. According to the invention, each leeboard (4, 5) consists of at least one upper element (4a, 5a) hinged to the fixed part (3) of the finkeel and a lower element (4b, 5b) hinged to the upper element, so that the leeboards can be folded up towards the fixed part (3) of the finkeel, to achieve lateral overall dimensions smaller than the width of the hull.

Abstract: The invention relates to a finkeel (3) for boats, having a fixed part (30) attached to the hull (2) of the boat and a movable part consisting of two lee-boards (32, 33) hinged with respect to an axis lying in the midplane (M) of the finkeel.

Abstract: An industrial system for measuring a physical quantity, related to an industrial process and/or application, comprising: first means for detecting said physical quantity and for transmitting first data and/or signals related to said physical quantity; second means for receiving said first data and/or signals, said second means being connected to said first means through one or more data/signal transmission lines; third means for reading said first data and/or signals and for programming said first means, said third means being detachable from said means and fixable in a remote position from said first means.

Abstract: A multifunctional operating unit which in the nautical field is used to produce electric power. Advantageously this unit is provided with one or more containers associated with an internal combustion engine, wherein sea water coming from outboard circulates. In this manner it is possible to achieve a compact unit wherein the engine actuates directly a desalination pump and/or the compressor of an aboard air conditioning system, whose condenser may be accommodated in the container.

Abstract: A differential pressure transmitter for process fluids is of the kind having a measuring transducer with a closed cell containing a filling liquid and a measuring diaphragm on both sides of which are arranged resistive, capacitive or inductive elements which are capable of converting a diaphragm deflection induced by differential pressure applied to the cell into electrical quantity changes. Inside the cell is provided at least one pressure sensitive component which is subjected to the pressure (s) of the filling liquid and is capable of providing an electrical output in accordance with the pressure values. This component is preferably a pasted carbon resistor, which permits output processed signal compensations in an electronic processing circuit to be made so as to minimize the effects of static pressure changes.

Abstract: An electronic transmitter for transmitting pressure values of industrial process fluids includes an inductive sensor employing a measuring diaphragm which is movable as a function of the pressure changes in the process fluids so as to produce corresponding changes in inductance and therefore corresponding signals which are suitably processed in an associated electronic circuit. The measuring diaphragm is provided with a rigid center forming or carrying one or more elements of a material exhibiting high magnetic permeability.
