    摘要： A system (7, 8, 21) for detecting the closure status of a two-shell grab bucket (2), equipped with a first (3) and a second (4) shell rotatably hinged to each other so as to be reciprocally moved between a completely open angular position and a completely closed angular position is described. The detecting system (7, 8, 21) comprises:
    - a magnetic field sensor (14), adapted to detect the presence of a magnetic field and to provide in output a signal bearing information on said magnetic field;
    - a first container (7) attached, or adapted to be attached, to the first shell (3) to be integral therewith in movement and comprising a first housing seat (12) which houses the magnetic field sensor (14);
    - a magnetic field generator (15);
    - a second container (8) attached, or adapted to be attached, to the second shell (4) to be integral therewith in movement and comprising a housing seat (13) in which the magnetic field generator (15) is housed;
    - a detection circuit (16) operatively connected to the magnetic field sensor (14) to receive said signal and discriminate whether said shells (3, 4) are in the completely closed angular position or not.

    摘要： System for preventing the onset, or mitigating the effect of thermoacoustic instability in annular combustors of premixed combustion gas turbines, that involves the inclusion in the plenum (7) of walls (15) oriented in a meridian direction so as to obstruct the circulation of tangential flows inside said space. These walls are situated in suitable azimuthal positions so as to contrast the onset of any standing oscillation modes; they shall therefore preferably divide the space in the plenum asymmetrically and the resulting annular volumes shall thus extend preferably along azimuthal sectors whose angular widths are not multiples of one another.
