  • Patent number: 11945592
    Abstract: An aircraft propelled by at least one turbojet engine on which power can be bled or injected via a high-pressure and/or low-pressure turbine shaft and including at least one gas turbine to provide power transients, having a system for converting and transporting electrical energy wherein each of the high-pressure and/or low-pressure turbine shafts is connected to a first doubly-fed asynchronous machine delivering, a first three-phase AC voltage over an AC distribution grid and a second polyphase AC voltage for a first AC/DC bidirectional converter supplying a DC voltage over a DC distribution grid, at least one second DC/AC bidirectional converter connected to the DC distribution grid converting this DC voltage into a third polyphase AC voltage supplying at least one second doubly-fed asynchronous machine engaged with a rotation shaft of the gas turbine, the second doubly-fed asynchronous machine further delivering a fourth polyphase AC voltage over the AC distribution grid.

  • Publication number: 20210020338
    Abstract: Disclosed is a device for applying marking tubes onto cables including: a driving mechanism for a cable along a driving axis; at least one buffer pipe in a producing position aligned with the driving axis, the buffer pipe having dimensions adapted both for a cable to be marked to run through the buffer pipe and for a number of marking tubes to be threaded onto the buffer pipe; a pushing unit engaging and pushing along the driving axis at least one first out marking tube of the marking tubes threaded on the buffer pipe until this first out marking tube exits the buffer pipe and is released onto the cable. Also disclosed is a method for applying marking tubes onto cables using a buffer pipe. The cable is always driven in the same forward direction and there is no limitation of cable length or marking tube number or location.

  • Patent number: 9876338
    Abstract: The invention concerns a device for stripping electric cables, comprising at least one stripping beam (10, 11; 110, 111; 209) emitted by a LASER source (1; 101; 201) and focused by an optical assembly (2-4; 102, 103; 203-208) into a focusing point (12, 13), called cutting point, and at least one track (6; 106) for receiving a portion of cable to be stripped, characterised in that each LASER source comprises a LASER diode (1; 101; 201) emitting a stripping beam of which the wavelength is between 400 nm and 460 nm, and preferably of the order of 445 nm.
