Publication number: 20090073918Abstract: The invention consists of a communication system that relays a satellite signal inside railway tunnels and relays the signals transmitted inside said tunnels towards the satellite, in such a way as to assure to vehicles transiting inside the tunnels a perfect transmission and reception quality even in the absence of satellite visibility. The system is based on a fixed terminal, for gallery illumination, connected to a fixed satellite station, and on a mobile terminal installed on the vehicle, connected to a mobile satellite terminal. The system automatically effects a switching action between satellite channel and radio channel in the tunnel, and vice versa, to assure the continuity of the vehicle-satellite connection. The system finds elective application for railway vehicles.Type: ApplicationFiled: March 30, 2006Publication date: March 19, 2009Applicant: FINMECCANICA S.p.AInventors: Paolo Conforto, Giacinto Losquadro, Rodolfo Mura

Patent number: 6339497Abstract: A panoramic periscope includes a central body (3, 3A) and a rotating head-piece (9) supported on the central body. Inside the central body, an optical path (21, 23, 101, 105, 109, 111, 113) for an optical beam (F,) coming from the head-piece (9) is provided. A viewing module (17) receives the optical beam, for observing the external scenery. A laser telemeter (19) is provided and, along the optical path, a separator element (10S) with an inner dichroic surface (105A) is passed through by the optical beam coming from the head-piece (9). The inner dichroic surface (105A) separates a laser beam coming from the head-piece (9) and deviating it towards a separate optical path (107) which conveys the laser beam towards the laser telemeter (19). The separator element (105) has an entry surface (105I) and an exit surface (105U) which are parallel with one another and passed through by the optical beam (FV), the surfaces being perpendicular to the optical beam (FV).Type: GrantFiled: July 17, 2000Date of Patent: January 15, 2002Assignee: Finmeccanica S.p.A.

Patent number: 6051279Abstract: Two different powders, one ceramic and the other of polymer particles, are fed separately into a jet of plasma of a conventional torch of a plasma spraying device by means of separate supply devices having respective powder injectors. The injection parameters of the two powders are established independently to achieve effective fusion of the ceramic particles and prevent complete combustion of the polymer particles. More specifically, the ceramic powder is injected along the axis of the jet of plasma, while the polymer powder is injected into a peripheral portion of the jet, at a predetermined distance from the jet axis, so that some of the polymer particles are incorporated in the ceramic coating deposited on a component for coating; and the polymer is subsequently removed by medium-temperature heat treatment to leave a porous ceramic coating with excellent thermal insulation properties.Type: GrantFiled: July 17, 1998Date of Patent: April 18, 2000Assignee: Finmeccanica S.P.A.
