A container apparatus includes a container body and a container lid. The container body defines a first internal cavity. The container lid is attached to the container body and defines a second internal cavity. The container lid includes protrusions extending within the second internal cavity to grind solid materials.

A hand-held sanding machine includes at least one sanding device for receiving or configuring a sanding apparatus. The sanding device includes at least one fan for conveying away material subtracted in a sanding procedure, at least one drive device for driving the sanding device, and at least one connecting housing unit which at least partially receives the sanding device. An internal wall of the connecting housing unit that delimits a fan receptacle region is configured for guiding an air flow generated by the fan. The internal wall is funnel-shaped about a rotation axis of a driveshaft of the drive device.

A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.

A method for producing a rolling sharpener having at least one grinding or polishing face for grinding and/or polishing a cutting tool, the rolling grinder being formed substantially from two rollers, a grip body to be arranged between the rollers and rotatably relative thereto, and a shaft to be supported rotatably in the grip body. To make correct operation of the rolling grinder user-friendly and to facilitate correct operation overall, each of the rollers is connected to the shaft in a frictionally engaged manner.

An enclosure assembly includes a pan that includes at least one shaft opening. A shroud at least partially surrounds the pan. The shroud extends transversely relative to the pan. A skirt surrounds a perimeter of the shroud and is moveable relative to the shroud.

A method for producing a roll grinder with two running rollers, a handle body arranged between the running rollers and can be rotated relative thereto, and at least one grinding or polishing surface. The method includes steps of: producing the handle body; measuring the handle body in order to determine the actual dimensions of the handle body; providing at least two differently dimensioned types of spacer elements, by means of each of which a different distance can be set between one of the running rollers and the handle body in the installed state of the roll grinder compared to at least one other type; selecting one of the types of spacer elements provided depending on the measured dimension of the handle body; and connecting the handle body to the running rollers to form the roll grinder while using at least one spacer element of the type selected.

An enclosure assembly includes a pan that includes at least one shaft opening. A shroud at least partially surrounds the pan. The shroud extends transversely relative to the pan. A skirt surrounds a perimeter of the shroud and is moveable relative to the shroud.

A rotor assembly for a floor processing machine includes at least three arms that extend outward from a central axis. Each of the at least three arms include a first surface opposite a second surface and are rigidly fixed from movement relative to each other. A spindle has a proximal end located adjacent the first surface on each of the at least three arms. A distal end has a shaft attachment opening. A distal end of each of the at least three arms include a tool head attachment surface.

A container apparatus includes a container body and a container lid. The container body defines a first internal cavity. The container lid is attached to the container body and defines a second internal cavity. The container lid includes protrusions extending within the second internal cavity to grind solid materials.
