Patents by Inventor Philippe LE GUYADER

Philippe LE GUYADER has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10052641
    Abstract: The disclosure relates to a centrifuge with a balancing mechanism and method of balancing such a centrifuge. The centrifuge includes a vertical shaft driven in rotation by a motor, and a mechanism for balancing the parts integral with said vertical shaft. The mechanism includes a plate integral with the vertical shaft, at least one compensating mass freely displacing on the plate, the mass being designed to limit the imbalance of parts integral with the vertical shaft, and a mechanism for blocking the compensating mass, the blocking mechanism being designed to immobilize the compensating mass on the plate when the rotation speed exceeds a determined value.

  • Patent number: 9669415
    Abstract: A laboratory centrifuge includes elements (10) for the locking of a lid in a closed position, which locking elements (10) include at least one strike (11) and at least one bolt (12) mobile between a locking position and an unlocking position. These locking elements (10) also include operating elements (15) including a motor shaft (16) that is coupled to the bolt (12) through transmission elements (17). The transmission elements (17) include a crank (18), extending the motor shaft (16), which carries an actuating member (19) bearing on a contact surface (12c1, 12c2) formed on the bolt (12), so that the driving into eccentric rotation of the actuating member (19) about the motor axis of rotation (16?) causes its circulation and bearing along the contact surface (12c1, 12c2) and the rotational control of the bolt (12) between its locking and unlocking positions.

  • Patent number: 9539588
    Abstract: A laboratory centrifuge includes two rotating parts (10, 11) associated by translation locking elements (13) including at least one female element (16) and at least one complementary male element (15). The male element (15) is associated with elements (20) for its operation to the inactive position, which include a rotating actuator member (21) carried by one of the rotating parts (11) and which cooperates with the male element (15) to ensure, by a rotational operation of the rotating actuator member (21) about its axis of rotation (21?), the displacement of the associated male element (15) from the active position to the inactive position.
