    Inventors: Olivier Carra, Alain Delevallee
  • Robotic vehicle having tiltable propulsion units
    Patent number: 5148882
    Abstract: An intervention vehicle of the type comprising propulsion units (4) that are tiltable by rotation about transverse carrying shafts (66), comprising advance and tilting driven shafts (8, 9) disposed coaxially inside each carrying shaft (66) and transmitting their motion via linear transmission elements (84, 90, 98) inside each propulsion unit for driving advance motion and tilting motion, and also constituting a speed reducer for the tilting motion. The invention is particularly applicable to the nuclear industry.

  • Transmission for a robotic vehicle
    Patent number: 5131484
    Abstract: A vehicle for interventions, in particular in buildings, characterized by the fact that it includes a scissor-like chain transmission (22, 40-24, 42) for transmitting the motion required between motors (10, 12) carried by the body of the vehicle (2) and propulsion units (4) having limited mobility relative to the body. The invention is particularly intended for the nuclear industry.

  • Method of installing a sleeve within an instrumentation tube of a nuclear fuel assembly
    Patent number: 4751039
    Abstract: A spacer sleeve is installed within an instrumentation tube of a nuclear fuel assembly comprising two end nozzles connected by tie rods and a plurality of fuel rod supporting grids distributed at axial intervals along the tie rods. The instrumentation tube has a first end received in an initially blind bore formed in one of the end nozzles and communicating with the outside by a coolant restriction.
