  • Patent number: 6276895
    Abstract: A fan has an associated centrifugal mechanism and a shutter, comprising a plurality of pivoted vanes and a central vane pivotally interconnected with a pair of heavy tie rods. The centrifugal mechanism is driven by the fan propeller and comprises a hermetic housing wherein are located, symmetrical spaced apart in rapport to the fan axis, at least a pair of radial sliding masses operatively connected with flexible cables to an axial sliding reciprocating actuator which is disposed at proximity of the shutter central vane. When the fan starts to operate in either direction by an electric motor, the radial masses slide radially by centrifugal action and pull the axial reciprocating actuator away from the central vane, allowing the shutter heavy tie rods, to open the shutter. When the fan stops, an internal spring housed within the axial sliding reciprocating actuator pushes it against the central vane causing the closing of the shutter.

  • Patent number: 6098475
    Abstract: A leverage mechanism actuating device includes a drive member with an output shaft to drive rotatably a rotary body around an axis. A force transmission member is moved relative to the rotary body between first and second positions by a centrifugal force generated by a rotary driving force applied by the output shaft on the rotary body. Movement of the force transmission member enables the force transmission member to convert the rotary driving force into a translational lifting force in a direction parallel to the axis. A leverage mechanism includes a fulcrum, and first and second locations. The first location is associated operably with the force transmission member. The second location is adapted to be connected to a toy. Thus, the first location is actuated by the translational lifting force of the force transmission member to result in a power output at the second location for initiating motion of the toy.

  • Patent number: 4811994
    Abstract: A hydraulic brake system having a hydraulic cylinder including a piston used for brake pressure modulation disposed between a master brake cylinder and at least one wheel brake cylinder in which the piston of the hydraulic cylinder is actuated mechanically by an electric-motor-driven centrifugal positioner. In an anti-skid system, the hydraulic cylinder can be used in combination with the centrifugal positioner for rapid reduction of brake pressure. It is also possible to embody the hydraulic cylinder and centrifugal positioner such that a brake boosting or anti-slip regulation takes place upon actuation of the centrifugal positioner. By the use of a centrifugal positioner, the piston can be displaced quickly and very precisely for either increasing or reducing brake pressure.

  • Patent number: 4294174
    Abstract: A rail system of the type in which a vehicle runs along a track to carry articles such as goods from one location in an industrial plant or other installation, to another location. At some point along the path an arm is provided for engagement with the vehicle and is swung with an angular velocity determined by the vehicle speed. A centrifugal clutch, effective when the angular velocity exceeds a predetermined level equivalent, say, to the maximum safe speed for the vehicle, can operate a cam to control a spring-loaded stop for the vehicle or car so that the stop can be rendered effective to bring the vehicle to standstill when the sensor detects the excessive speed.

  • Patent number: 4194412
    Abstract: A mechanism is described for selectively engaging a handwheel with a shaft to manually rotate the shaft with the handwheel. The mechanism automatically disengages the handwheel from the shaft when the shaft is rotated by a power source above a predetermined speed. Further, when the shaft is thusly rotated by a power source, the mechanism does not allow an operator to engage the handwheel with the shaft. The mechanism includes a complementary groove system and a cam, one being on the shaft and the other on the handwheel. The groove system comprises at least two laterally-spaced grooves encircling the axis of the shaft, and a third groove spiralling about the axis between the first and second grooves. In one embodiment, the cam is mounted on the handwheel and rides in the grooves in the shaft. When the handwheel is axially depressed, to engage the shaft, the cam rides in the innermost encircling groove.
