  • Patent number: 11155451
    Abstract: A forklift truck mounted on wheels comprises a drive system and tilting lifting means, a fork (1) adapted to lift loads with the aid of two substantially parallel arms (2) carried by uprights (3) which are substantially vertical or oblique depending on the working position, said fork (1) comprising a loading stop (10) disposed on each of the uprights (3) of the fork, each stop (10) comprising a bearing face (11) for loads having a straight profile and an angled docking face (12) for loads having a circular arc profile.
    Type: Grant
    Filed: June 22, 2018
    Date of Patent: October 26, 2021
    Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN
    Inventors: Sylvain Grandjean, Giancarlo Pegoraro
  • Patent number: 10955385
    Abstract: A sound measurement system intended to be installed on a motor vehicle, the system comprising: a microphone, an element for supporting the microphone, mechanical means for protecting the microphone against various projections (water, dust, etc.) from the environment of the vehicle, and mechanical means for protecting the microphone from airborne noise originating from the routing of the sound wave between the source and the measurement (cavity noise) and from the environment of the measuring system (turbulence around the measuring device), the various mechanical protection means being separate or combined. A motor vehicle may be provided with such a system.

  • Patent number: 10780656
    Abstract: An apparatus for preparation of a continuous composite element formed of reinforcement fibers impregnated with a resin that includes photo-initiators for curing. Reinforcement fibers are pulled through a vacuum chamber (110) and then a vertical impregnation chamber (122) where impregnation with the resin occurs. The elongate composite is then deposited onto a rotating wheel of conformation (140). During rotation, a radiation source (146) such as e.g., LEDs (light emitting diodes) are used to activate the photo-initiators and provide at least partial curing of the resin. From the wheel of conformation, the continuous composite element is passed along a vertical course (148) where additional radiation sources (150) activate the photo-initiators and provided additional curing.
