Abstract: The present invention relates a grinding device 1 for the machine-based grinding of rotor blades 100 for wind energy systems, comprising a belt grinding unit 10 with a circulating grinding belt 12.

Abstract: A backing plate unit for a rotary grinding machine, includes a backing plate with a front face for mounting a grinding disc and a back face opposite the front face, a drive shaft that can be attached to the tool adaptor of the rotary grinding machine, and a suction hood that is rotatably fixed to the drive shaft. The backing plate 10 includes suction openings that penetrate the backing plate so that the suction hood 30 vacuums dust through the backing plate to the back face of the backing plate.

Abstract: A motorized wheelchair includes a frame, a battery support assembly that supports a battery box and is connected to the frame, first and second power drive assemblies disposed on each lateral side of the wheelchair, first and second rear wheels driven by the power drive assemblies, first and second castor wheels driven by the power drive assemblies, and first and second castor wheels that are pivotally connected to said frame. The battery support assembly is pivotally connected to the frame by a first connecting arrangement, so that said battery support assembly can pivot around a first longitudinal axis. The battery support assembly is pivotally connected to the first connecting arrangement by a second connecting arrangement, so that the battery support assembly can pivot around a second lateral axis.

Abstract: A device for blocking workpieces for the processing and/or coating thereof, has a support surface for positioning the workpiece to be blocked, a blocking station in which the workpiece can be blocked on a blocking piece by a temporarily deformable blocking material, and a transport device which has a retaining head for the workpiece and by which a relative movement can be created between the workpiece being retained at the retaining head, and the support surface and the blocking station. The transport device has at least four position-controlled movement axes, by which to position the workpiece in a defined manner in consideration of the orientation and geometric information relative to a blocking piece located in the blocking station, and can be retained in the defined relative position to the blocking piece during blocking while leaving a blocking material accommodation gap between the workpiece and the blocking piece.

Abstract: A grinding member is formed as a shape-elastic monolithic element and has at least partially a three-dimensional cell structure on a grinding surface of the grinding member. The grinding surface has a first abrasive agent. The grinding surface has at least partially an open-cell structure with open cells. The open cells of the grinding surface communicate via passages with cells of the interior of the grinding member. The cells in the interior of the grinding member that communicate via passages with the open cells of the grinding surface contain a second abrasive agent.

Abstract: An abrasive element support having an axis of rotation and a fastening surface for attachment of an abrasive element is designed as a self-sucking device in the form of a radial fan device. The fastening surface has a fastening element such as a hook and loop fastening element that allows passage of grinding particles in a direction parallel to the fastening surface. The radial fan device has intake and exit openings, wherein the intake opening is arranged closer to the axis of rotation than the exit opening. The intake and exit openings communicate through at least one acceleration chamber of the radial fan device.

Abstract: An abrasive belt for a belt grinding machine has a support layer, an intermediate layer connected to the support layer, and an abrasive layer connected to the intermediate layer. The support layer transmits a drive output of the belt grinding machine onto the abrasive layer. The abrasive layer allows flow of grinding particles through the abrasive layer. The intermediate layer also allows flow of the grinding particles through the intermediate layer, and the support layer allows flow of the grinding particles through the support layer.

Abstract: A cutting member to be connected to a material removing device such as an annular bit, a drilling bit, a cutting bit, a saw and the like, consists of a binder agent, diamond grains and a small amount of hard material particles. The hard material particles reinforce the binder agent and supports the anchorage of the diamond grains.

Abstract: A grinding member attachable to a grinding disc, an attachment plate of a grinding machine, or a manual holder, and including an abrasive-containing layer, and a perforation substantially uniformly distributed over at least a portion of a surface of the abrasive-containing layer and extending through an entire thickness of the abrasive-containing layer, with the perforation being formed of a plurality of openings so spaced from each other that unhindered suction of abrasive dust is insured; and adapter for attaching the grinding member.

Abstract: A device for releasably connecting first and second rods together is characterized by a connecting flange mounted on one end surface of the first rod by a self-tapping screw. The flange includes at least one latch projecting from a surface thereof to engage a recess in the first rod in a form-locking manner. With the flange mounted on the end of the first rod, the first rod is connected with a side of the second rod so that the rods have perpendicular longitudinal axes. The second rod contains a groove along its side in which a pair of nuts are retained. Fastening screws pass through grooves in the first rod, through openings in the flange and into tap holes in the nuts to threadably connect the first rod with the second.

Abstract: In an apparatus for voice training, on several points of a student's body measuring devices are provided, which are connected to optical display devices. At each of these measuring devices, a pressure sensor amplifier is connected with an analog multiplexer, and a sound-pressure measuring device is directly connected to the respective display device.
