The device also includes a resetting device for displacing the stator tools in a radial direction to set the working clearance. The resetting device for the stator tools include at least one tilted support surface, which directly or indirectly forms a contact surface for the stator tools. Whereby, the support surface is slideable with respect to the stator tools in order to adjust the working clearance.Type: GrantFiled: November 29, 2007Date of Patent: July 20, 2010Assignee: Pallmann Maschinenfabrik GmbH & Co. KGInventors: Hartmut Pallmann, Jochen Heib

Patent number: 7677483Abstract: A substrate destruction apparatus for destruction of paper and optical discs, wherein first and second shafts are used for shredding paper fed through a paper receiving opening and second shaft is shared such that the second shaft and a stationary structure are used to damage optical discs. First and second shafts are provided with a plurality of cutter elements that interleave with when rotated relative to each other during use in a paper mode. When the apparatus is operated in a disc destruction mode, the shared second shaft is rotated in an opposite direction than the paper shredding direction and interleaves with the stationary structure to at least damage an optical disc fed through the disc receiving opening. Cutting elements on the second shaft have radial projections and protrusions for damaging at least the surface of the disc with a plurality of scratches, depressions, or cuts, rendering the disc unreadable.Type: GrantFiled: April 4, 2007Date of Patent: March 16, 2010Assignee: Fellowes, Inc.Inventors: Dmitry Romanovich, Vadim Romanovich

Publication number: 20100058942Abstract: The invention relates to an apparatus for compressing empty containers, in particular of beverage bottles or beverage cans made out of plastic, in particular out of polyethylene terephthalate PET, or tin plate. The apparatus according to the present invention has a cutting and pressing unit as well as means for driving and for controlling the cutting and pressing unit, wherein the cutting and pressing unit contains at least two cooperating, oppositely rotating rollers disposed at a distance relative to each other with respect to their rotation axes, wherein each roller has several disks in each case disposed towards each other with an axial distance (free space). According to a special further development it is proposed that at least in the operating region of the two rollers there are disposed axially next to each other a first working region for a compressing of containers made out of plastic and a second working region for a compressing of containers made out of metal.Type: ApplicationFiled: September 10, 2009Publication date: March 11, 2010Inventor: Hermann Schwelling

Patent number: 7552883Abstract: The invention relates to a crushing device, which includes a frame structure and a rotor mounted rotatably in bearings in it. In addition, shredder elements are arranged in connection with the frame structure and the rotor, and a hydraulic motor is connected to the rotor through a power transmission. The material fed to the crushing device is arranged to travel through the shredder elements while at the same time being crushed into smaller pieces when the rotor is rotated by the hydraulic motor. At at least one end of the rotor, the rotor is fitted to the frame structure by means of a pivot joint, which permits a difference of angle between the rotor and the frame structure.Type: GrantFiled: August 22, 2005Date of Patent: June 30, 2009Assignee: Tana OyInventors: Kauko Kinnunen, Hannu Heinäsenaho, Hannu Urpalainen

Patent number: 7523880Abstract: An ice bin apparatus includes a case with an open upper portion for receiving pieces of ice. A guide within the case guides the received ice pieces and an auger adjacent to the guide transfers the guided ice pieces. A grinder for grinds the transferred ice pieces and a diffuser located at a bottom portion of the case discharges the ground ice. A shutter having a hinge that allows movement thereof opens or closes the diffuser for selectively discharging the ground ice therethrough, and a shutter press prevention part is capable of preventing the shutter from being pressed down during the grinding of ice pieces performed by the grinder.Type: GrantFiled: February 28, 2006Date of Patent: April 28, 2009Assignee: LG Electronics Inc.Inventors: Nam-Gi Lee, Wook-Yong Lee
