The actuators are powered by an electrical energy generating device, such as a photo cell or a photovoltaic element, which is coupled to the machinery and located across an air gap from a source of radiant energy such as an array of light emitting diodes.

  • Patent number: 8459147
    Abstract: A rotor balance adjusting member and a rotor balance correction method are disclosed. The rotor balance adjusting member has a ring member fixed to a pulley concentrically and comprises a weight and a clip member which fixes the weight to the ring member. The ring member has an outer side fit-in slot, and inner side fit-in slot, an outer side stop slot, and an inner side stop slot. The clip member comprises an elastic material and moves in a circumferential direction regulated by the outer side fit-in slot and the inner side fit-in slot. The weight fixed to the clip member is arranged in a position which counters the inner side of the ring member when the clip member is fitted in the ring member.

  • Publication number: 20130118300
    Abstract: A shaft damper of a transmission is provided to improve an NVH characteristic such as rattle noise of a transmission by effectively reducing target resonance as a problem in whole rpm ranges by adding a structure to minimize one resonance and additionally reduce the resonance with respect the other resonance between two resonances while converting the target resonance as the problem into two divided resonances by mounting a structure which applies inertia to an input shaft or an output shaft, a counter shaft, or a PTO shaft of the transmission.

    Abstract: Avalanche control system and method using one or more chambers in an avalanche-prone area to control the removal of snow or other material which might avalanche. The system includes a plurality of spaced housings made of a solid material like “shock-crete” and an asymmetric flywheel coupled to a motor which is controlled by a signal to warm up and turn on at a desired time to vibrate the housing and cause removal of loose snow or other material and/or the compacting of that material to make avalanching less likely.

  • Patent number: 8342058
    Abstract: A torsional vibration damper includes an inertia mass and a rotating shaft or hub with an elastomeric ring between the inertia mass and the rotating shaft or hub. A large portion of said elastomeric member is located in a channel located either in the inertia mass or in the hub. This allows one to achieve high contact pressure without creating a significant fatigue on the elastomeric member. This can be used with either a crankshaft damper or an internal or external drive shaft damper.

  • Publication number: 20120312118
    Abstract: A mass balancing device for balancing free inertial forces and/or free moments of inertia of a reciprocating internal combustion engine (1). The mass balancing device includes two balancer shafts (3, 4) rotating at the same rotational speed in opposite directions of rotation, and a transmission (5) arranged between the crankshaft (2) of the internal combustion engine and the balancer shafts. The transmission drives the balancer shafts at a transmission ratio of crankshaft rotational speed to the balancer shaft rotational speed that is non-uniform over the crankshaft angle such that the angular speed of the balancer shafts is at the maximum at the piston dead centers. The mass balancing device is intended to be configured for an internal combustion engine of multi-cylinder design and the mean value of the transmission ratio is intended to be 1:2.

    Abstract: An eddy-current actuated balancer includes a barrel having a locating wall at one end thereof; two balancing wheels mounted around the barrel and carrying a respective counterweight at the border, a washer set between the balancing wheels, an elastic ring and a lock ring and a pulsed magnetic field generator mounted on each balancing wheel. The balancing wheels, the washer and the elastic ring are clamped between the locating wall of the barrel and the lock ring. Each pulsed magnetic field generator is controlled to generate a pulsed magnetic field acting upon the associating balancing wheel during its rotation for inducing an eddy current that causes the associating balancing wheel to make an angular displacement relative to the barrel for balance adjustment.
