  • Patent number: 8286531
    Abstract: An automatic balancing device for counterbalancing an out-of-balance mass includes a plurality of counterbalancing masses, each of which is movable in a circular path about the axis so as to generate a balancing force. The balancing forces combine to produce a resultant balancing force which varies between minimum and maximum values. At a first speed of rotation of the body about the axis, the movement of at least one of the counterbalancing masses is restrained so that a substantially constant, non-zero resultant balancing force is produced, the resultant balancing force being freely movable about the axis. At a second speed of rotation of the body about the axis, the counterbalancing masses are free to adopt a position in which the out-of-balance mass is counterbalanced. The device allows at least partial counterbalancing of the out-of-balance mass at speeds below the critical speed of the system in which it is used.

  • Patent number: 8252705
    Abstract: A bi-layer, woven geotextile fabric has interwoven first and second layers. The first layer is over and under woven through the second layer in a pre-determined pattern so that the first layer has portions which face a first side of the second layer and portions which face a second side of the second layer. Monofilaments in the warp direction of the first layer have a pre-determined differential heat shrinkage characteristic that is greater than the monofilaments in the warp direction of the second layer. Closed cells defined by the pattern of the over and under weave are disposed on the first and second sides of the second layer. Shrinkage of the monofilaments in the warp direction of the first layer provide for a separation of a portion of the second layer from the first layer at the cells.

  • Publication number: 20120074806
    Abstract: A magnet that includes a composite body and at least one reinforcing element. The reinforcing element is embedded within the body and increases the radial strength of the body. As a result, the magnet is able to rotate at higher speeds without fracturing. Additionally, methods of manufacturing the magnet are described.

  • Publication number: 20110250809
    Abstract: A woven geosynthetic fabric is disclosed having a first weft yarn, a second weft yarn, and a stuffer pick woven in the weft direction of the fabric. A warp yarn interweaves the first and second weft yarns and the stuffer pick. The first weft yarn and the second weft yarn having different cross-sectional shapes. At least a portion of the fabric has a plurality of weft yarn sets with stuffer picks respectively disposed and woven between the weft yarn sets. Each weft yarn set has two first weft yarns and two second weft yarns. One of the two first weft yarns is adjacent one of the two second weft yarns and stacked on the other second weft yarn. The adjacent second weft yarn is stacked on the other first weft yarn.

  • Patent number: 7509825
    Abstract: Provided herein is an automatic balancing device for counterbalancing an out-of-balance mass present in a rotating body. The automatic balancing device includes a chamber with an outer wall and an axis, first and second counterbalancing masses constrained to move freely in a circular path about the axis within the chamber, and a viscous fluid provided in the chamber so as to provide viscous coupling between the outer wall of the chamber and each of the counterbalancing masses. The counterbalancing masses may be arranged so that the first counterbalancing mass leads the second counterbalancing mass when the device is in use. A constraint may be provided with the device so as to prevent the first counterbalancing mass from leading the second counterbalancing mass by more than substantially 180°.
