Patent number: 4852660Abstract: A grader has a grader blade which can be pressed against the ground or lifted off it by means of piston-cylinder drives. To be able to vary the downard pressure of the grader blade in its float position, either the piston chamber or the piston ring chamber of each drive can be charged with a working fluid under pressure when the grader blade is in the float position, so that the corresponding drive exerts a force on the grader blade which increases or decreases the downward pressure of the grader blade on the ground. While still allowing the grader blue to follow the contour of the ground.Type: GrantFiled: October 28, 1988Date of Patent: August 1, 1989Assignee: O & K Orenstein & Koppel AktiengesellschaftInventors: Gustav Leidinger, Gunther Proll, Walter Kolb

Patent number: 4799595Abstract: The invention relates to an apparatus for classifying powdered bulk materials, particularly ground clinker, limestone or cement raw material, by air sifting. The material to be classified is fed to the cover plate of a cylindrical rotor and charged into a sifting space having the shape of a cylindrical ring which extends between the rotor and a stationary vane ring which is spaced from and surrounds the rotor. While the coarse material descends in the sifting space, the fine material is conveyed into the inside of the rotor and fed to a subsequent separating device for the separating of fine material and sifting air. In order to simplify the construction and stocking, both the rotor and the housing surrounding it are assembled in building-block fashion from a plurality of identical sections, at least one tangential air inlet connection being associated with each housing section. Each housing section can have associated with it at least one cyclone of its own with its own fan.Type: GrantFiled: December 19, 1986Date of Patent: January 24, 1989Assignee: O&K Orenstein & Koppel AktiengesellschaftInventor: Ulrich Binder

Patent number: 4748754Abstract: The shovel for an excavator has teeth arranged at a distance apart from one another on its digging edge. The areas of the edge of the shovel between the teeth are equipped with caps that are relatively resistant to wear and are put on in such a manner that they can be replaced, and have a short hook-like projection which engages under the edge of the shovel and a long leg which fits over the edge of the shovel. Secured to the upper surface of the shovel between the teeth of the shovel are retaining pieces which can fit together with the legs of the caps when the caps are put onto the edge of the shovel and which cooperate with them in an interengaging manner to prevent the legs of the caps from being lifted off from the upper surface of the shovel. Detachable securing members hold the legs of the caps and the retaining pieces together in the direction in which they can be fit together.Type: GrantFiled: April 3, 1987Date of Patent: June 7, 1988Assignee: O&K Orenstein & Koppel AktiengesellschaftInventor: Dieter Schwappach
