  • Publication number: 20230339270
    Abstract: A rotary feed-through, designed to transfer a fluid between two entities in rotary motion with respect to one another. The rotary feed-through includes an inner cylindrical ring and an outer cylindrical ring, which are free to turn with respect to one another and provided with channels for passage of the fluid. The channels are connected via at least one annular space axially delimited by seal rings housed in a cylindrical seat. The cylindrical seat faces radially outwards or inwards and is axially delimited, on one side, by an axial abutment of the inner and outer cylindrical rings and, on the other side, by an axial abutment of a lid, a closing ring, or an intermediate ring. The seal rings are interference fitted to the inner or outer cylindrical ring and provided with an elastic portion for contact with the surface of the inner or outer cylindrical ring.

  • Publication number: 20220402314
    Abstract: The present invention relates to a system and method for measuring the length of a footprint of a tyre (10). The system comprises a first electronic device (1) and a second electronic device (2), each of which is configured at least to acquire, filter, store and sent data, and a processing unit (3), external to said electronic devices (1, 2), configured at least to receive and process the data sent by each electronic device (1, 2), to measure the length of a footprint on the basis of an angle (?) arranged between a first axis (B1) passing through the centre (O) of the tyre (10) and a first contact point (CP1) between a portion of said tyre (10) and the ground and a second axis (B2) passing through the centre of the tyre (10) and a second contact point (CP2) between said portion of said tyre (10) and the ground.

  • Publication number: 20220357239
    Abstract: The present invention relates to the system for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted. In particular, said system comprises a first electronic device (1) and a second electronic device (2), each of which is configured at least to acquire, filter, store and send data, and a processing unit (3), external to said electronic devices (1, 2), configured at least to receive and process the data sent by each electronic device (1, 2), in order to measure said slip by measuring an angle (?) and comparing the value of this angle with respect to at a reference angle ?ref. The present invention also relates to method for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted.

  • Patent number: 9281897
    Abstract: An electro-optical single-sideband modulator comprising: an electro-optical substrate; a bimodal optical waveguide structure formed in the substrate to support different optical modes having associated optical frequencies and optical propagation constants and comprising an optical input to receive an input optical carrier signal having an optical frequency, and a pair of optical outputs to output corresponding SSB modulated optical signals, each having an optical frequency spectrum with a single side lobe; and an electrode structure formed on the substrate to receive an input electrical modulating signal having an associated electrical frequency and electrical propagation constant, and to responsively apply an electrical field to the bimodal optical waveguide structure.
