Patent number: 9498861Abstract: In a method and a device for machining an elongate workpiece that is not rotationally symmetrical in the form of turbine blades, the workpiece is supported by a steady rest that has clamping elements for clamping the workpiece on the cross-section thereof that is not rotationally symmetrical. After clamping the workpiece, the steady rest moves with its open clamping elements along the longitudinal axis of the workpiece into a supporting position. During movement of the steady rest into the supporting position and/or while the supporting position of the steady rest is being changed, a collision between the open clamping elements of the steady rest and the workpiece is prevented by a program-controlled rotation of a rotary part of the steady rest.Type: GrantFiled: September 20, 2011Date of Patent: November 22, 2016Assignee: Starrag AgInventors: Horst Keller, Roland Geiger

Publication number: 20070084162Abstract: An apparatus for purification of air comprising comprises a housing having inlet openings for supplying the air to be cleaned and outlet openings for discharging the cleaned air, a filter system disposed in the housing, and a fan arranged to draw air through the housing and filter system. The filter system includes at least one tubular or bag-shaped fleece filter which is arranged on top of a carrier structure and at least one secondary filter element which has a filter fineness which is smaller than the filter fineness of the fleece filter. The entire apparatus is arranged either stationarily or moveably in regions of greater to lesser dust concentration. The cleaned air is conveyed to the region with the higher local dust concentration and thereby significantly decreases the local dust concentration.Type: ApplicationFiled: September 13, 2006Publication date: April 19, 2007Applicants: Mann & Hummel GmbH, Keller Lufttechnik GmbH & Co.
