Patent number: 8286531Abstract: 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.Type: GrantFiled: November 7, 2005Date of Patent: October 16, 2012Assignee: Dyson Technology LimitedInventors: David Michael Jones, Matthew Damian Harrison, Matthew Charles Edward Wilson

Patent number: 8252705Abstract: 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.Type: GrantFiled: March 23, 2010Date of Patent: August 28, 2012Assignee: Nicolon CorporationInventors: Kevin Nelson King, David Michael Jones, Greg L.
