Abstract: A drive arrangement for a bicycle includes a pawl freewheel, the pawl freewheel having a first ring, at least two pawls movably mounted on the first ring, and a second ring having a toothing. The at least two pawls are unevenly spaced in the circumferential direction on the first ring. The drive arrangement further includes at least one sensor device configured to detect a deformation of the first ring of the pawl freewheel due to an applied drive force.

Abstract: A drive arrangement for a bicycle includes a detent freewheel mechanism (14). The detent freewheel mechanism (14) has a first ring (20) with detents (24), which are movably supported thereon, and a second ring (22) having a tooth arrangement (26). In addition, the drive arrangement has at least one sensor apparatus, which is configured to detect a deformation of the first ring (20) of the detent freewheel mechanism (14) on the basis of a drive force which is applied. The sensor apparatus (24) has one associated deformation sensor (28) in each case per detent (24).

Abstract: A tool assembly and a method for manufacturing and sealing a tool assembly for manufacturing an article includes building a tool assembly using additive manufacturing or 3D printing processes.

Abstract: An antiviral filament and an antiviral three-dimensionally printed component including an antiviral polymer including a base polymer, and an antiviral agent incorporated in the base polymer, wherein the antiviral agent exhibits a phase transition temperature of 200 degrees Centigrade or greater. A method of fabricating a three-dimensional component including feeding an antiviral filament into an extrusion nozzle, the antiviral filament comprising an antiviral polymer; applying heat and pressure to the antiviral filament to melt the antiviral filament in the extrusion nozzle; extruding the antiviral filament from the extrusion nozzle; depositing the extruded antiviral filament into layers; and forming a three-dimensional component from the layers of extruded antiviral filament.

Abstract: A leveling rod attachment including a first telescopic assembly, a second telescopic assembly and a clamper assembly is disclosed herein. The first telescopic assembly includes vertical rods being slidably connected one to each other. Each of the vertical rods has measurement indicia. The second telescopic assembly includes horizontal rods being slidably connected one to each other. Each of the horizontal rods has measurement indicia. One of the horizontal rods has a bubble level mounted thereon. the clamper assembly includes a clamper and latches. The clamper is attached to the second telescopic assembly. The damper slidably mounts the second telescopic assembly to the first telescopic assembly. The latches secure length of the first telescopic assembly and length of the second telescopic assembly.
