  • Patent number: 9013070
    Abstract: The present application describes an apparatus (1) for sectioning an electric energy flow in one or more conductors (15) of an electric energy generating plant (100), comprising a pneumatic circuit (4) that feeds a plurality of pneumatic remote switches (5), and a control unit (2) that controls such a pneumatic circuit (4); the pneumatic remote switches (5) intercept conductors (15) of an electric energy generating plant (100) and are able to interrupt the passage of current both for automatic safety intervention and for manual or automatic controlled intervention; it also describes an electric energy generating plant (100) comprising a plurality of electrical generators (6) connected in series and the aforementioned sectioning apparatus (1), the pneumatic remote switches (5) of which intercept at least one conductor (15) of such a plurality of electrical generators (6).

  • Publication number: 20050115419
    Abstract: An automatic device for heating and frothing a liquid, in particular milk, comprises a container for the liquid, inside which a first tube for introducing pressurised steam into the liquid is removably mounted. The first tube has an inlet in correspondence of the bottom of the container, for receiving steam from a duct located within a support base of the container, and is secured, for at least part of its length, to a second tube for introducing air into the liquid.
