Abstract: The invention relates to a piece of furniture (30), comprising at least one support rod (10) and at least one first plate (20), on which the support rod or support rods (10) can be installed. The first plate (20) has one or more first openings (21). Into each of said first openings (21), a support rod (10) can be inserted at one end (11) thereof, and each of the support rods (10) can be mounted perpendicular on the first plate (20). The support rod (10) has a star-shaped axially symmetric cross-section (13), which is tapered at the one end (11) facing the first plate (20). The shape of the first openings (21) is adapted to the star-shaped cross-section (13) of the support rod (10), preferably in such a way that the shape of the first openings is designed similarly to the star-shaped cross-section (13) of the support rod (10).

Abstract: The invention relates to a method for the multi-stage grinding of workpieces (20) made of hard mineral materials using a robot (10). To this end, the workpiece (20) is moved into a processing region (21) and measured and/or oriented there by the robot (10). The robot (10) comprises a grinding head (11) by way of which it then takes up a first abrasive (14) preferably from a storage container (30) and starts a first grinding process. After the first grinding process is complete, the robot (10) releases the first abrasive (14) again and then takes up a second abrasive (14), preferably from the same or some other storage container (30). Then the robot (10) starts a second grinding process, and after the latter is complete, releases the second abrasive (14) again. One or more further grinding processes may be provided, but the grinding method can also be finished after the second grinding process.

Abstract: A device for supplying electrical energy to a load. A supporting element made of electrically insulating material is provided, which has at least one electrical strip conductor formed from an electrically conductive layer. At least one electrically conductive contact face per strip conductor is provided on the source side, via which the strip conductor is contactable with the voltage source. A flat plug that includes the load-side ends of the strip conductors is provided on the supporting element and effects the electrical connection to the load. A system for electrification of an electrical load on a furniture item is provided. At least one device, a support and at least one vertical profile are provided. The device is mounted on the support and the strip conductors of the support are electrified by inserting the support into the profile. For that purpose, the profile has at least one vertically arranged conductor rail.

Abstract: Construction for panel covering of structural columns.

Abstract: A scaffold which can be readily assembled and disassembled. The cross numbers are outfitted with retractable hooks for, when extended, engagement with slots in the uprights. With the hooks extended, wedges secure them in tight engagement with the slots. The hooks are unremovably mounted on the cross members, and the wedges are also unremovably mounted.
