  • Patent number: 10788085
    Abstract: A magnetorheological fluid clutch apparatus comprises an input rotor adapted to be coupled to a power input, the input rotor having a first set of at least one input shear surface, and a second set of at least one output shear surface. An output rotor is rotatably mounted about the input rotor for rotating about a common axis with the input rotor, the output rotor having a first set of at least one output shear surface, and a second set of at least one output shear surface, the first sets of the input rotor and the output rotor separated by at least a first annular space and forming a first transmission set, the second sets of the input rotor and the output rotor separated by at least a second annular space and forming a second transmission set. Magnetorheological fluid is in each of the annular spaces, the MR fluid configured to generate a variable amount of torque transmission between the sets of input rotor and output rotor when subjected to a magnetic field.

  • Publication number: 20090261529
    Abstract: A board game to emulate the game of baseball wherein dice are rolled with each number signifying a action by the batter. Supplemental dice are also employed for use by both the defensive team and offensive team to force other actions such as steals, double plays, and the like.

  • Publication number: 20050155475
    Abstract: A saw has a first saw head and a second saw head and is provided with an optimized structure of the saw heads by reducing a number and dimensions of components thereof, thereby allowing to strike an optimized balance between the cutting path, the cutting height and the dimensions of the cutting bench of the saw. Moreover, the saw of the present invention includes a rear movement mechanism allowing a movement of the blade from the rear end of the saw, which permits to accommodate a blade of an increased diameter, and a crosscut indexation mechanism.
