Abstract: The invention relates to a method of disinfecting clean rooms for administration of a disinfectant, which is sprayed onto the surfaces to be disinfected by means of an unmanned aerial vehicle from the air; the disinfectant being stored on board the aerial vehicle in at least one tank. The invention further relates to a device for performing this method, comprising an accordingly adapted unmanned aerial vehicle.

Abstract: A method and apparatus for feeding joining elements to a joining tool is presented. The joining tool may be movable by a programmable handling unit, and a magazine for receiving at least one joining element may be mounted on the joining tool. The magazine may be moved to a filling station that has a tubular section with an outlet opening. An inlet opening of the magazine may be oriented in relation to the outlet opening. At least one joining element may be conveyed to the tubular section so that it passes through the tubular section, the outlet opening, the inlet opening, and into the magazine. During the orienting, the magazine may be oriented in relation to the outlet opening such that the magazine is spaced apart from the filling station during the conveying of the at least one joining element.

Abstract: A compensating device for a tool for fitting an element into a hole of a workpiece, the tool mounted axially on a housing by the compensating device, the compensating device having a clamping arrangement arranged between the tool and the housing and including at least two controllable clamping units. The clamping units are operable in an initial state to secure the tool rigidly to the housing, and in a compensating state to set different degrees of freedom defining possibilities of movement of the tool, and the compensating device also includes a control unit which is designed to activate the clamping units.

Abstract: A method for joining a fastening element on to a surface portion of a component, the fastening element having an adhesion face, on to which there is applied an adhesive that is thermally meltable and thermally settable, comprising the steps of: pre-heating the adhesive to a first temperature (T1), in order to activate the adhesive; pre-heating the surface portion to a second temperature (T2); and placing the adhesion face on to the surface portion; the adhesive undergoing main heating, to a third temperature (T3), after the adhesion face has been placed on to the surface portion, in order to set the adhesive and thereby permanently fasten the fastening element to the component.
