20120267978 | SQUIRREL-CAGE ROTOR FOR ASYNCHRONOUS MOTORS - A squirrel-cage rotor for asynchronous motors is provided with a lamination stack made of a magnetic material and a plurality of bars, the intermediate portions of which engage respective slots of the lamination stack; the end portions of the bars protrude with respect to the lamination stack at both axial ends of the rotor and are fixed to two shorting rings; a plurality of spaces are defined, axially, by the lamination stack and the shorting rings, and tangentially by the end portions of the bars; part of such spaces is engaged by stiffening blocks arranged in contact with the end portions of the adjacent bars. | 10-25-2012 |
20120208470 | FAULT DETECTION METHOD AND SYSTEM - A method of detecting faults in a member having a first and second face opposite each other and communicating fluidically in the presence of at least one fault; the method including the steps of: generating a first sound signal by means of a transmitter, so that the first sound signal interacts with at least one portion of the first face of the member; arranging a receiver, configured to receive a second sound signal, close to a respective portion of the second face of the member corresponding to the portion of the first face, the second sound signal being the outcome of the first sound signal interacting with the member; moving the receiver, close to the second face of the member; generating a detection signal, by means of the receiver, as a function of the received second sound signal; calculating, at a number of instants (t | 08-16-2012 |
20090133600 | Reinforcing Assembly for a Tubular Cross Member of a Rail and Tram Car Bogie - A reinforcing assembly for a tubular cross member of a rail and tram car bogie has a liner elongated along an axis, deformable radially, and insertable axially inside one end of the tubular cross member to line an inner cylindrical surface of the end; a tubular body insertable coaxially inside the liner; and a number of radial forcing devices, which are activated to force the tubular body, and hence the liner, radially outwards to lock the liner frictionally against the inner cylindrical surface of the cross member. | 05-28-2009 |
