Abstract: A rotor blade mold for producing a rotor blade, a method for producing a rotor blade mold, the use of a rotor blade mold, a spray device for producing an insulation layer, and an adhesive product. A rotor blade mold for producing a rotor blade or a part of a rotor blade, in particular of a wind turbine, comprising a mold insert, having a mold side which forms a cavity for molding a rotor blade or a part of a rotor blade, and a structured side facing away from the mold side, an insulation layer arranged on the structured side, and having an adhesive, and a plurality of pouring elements made of an insulation material.

Abstract: The invention relates a method of producing a rotor blade, according to which a preform is produced as a semi-finished textile product from a number of material sheets of textured laid scrim mats, preferably for use in a subsequent vacuum infusion comprising the steps of: provision of a mold for the preform in a laying frame, provision of a textured laid scrim mat in the form of a roll of the material sheet on a laying roll, automatic rolling out of the textured laid scrim mat and automatic application of an adhesive to the textured laid scrim mat in the mold in the laying frame.

Abstract: A method of microscopy and an illumination optical device with a hollow cone for a microscope, the illumination device includes a first conical lens (1) able to receive a collimated incident light beam (10) and form a conical light beam (20), a second conical lens (5) arranged in such a way as to receive the conical light beam (20, 40) and to form a cylindrical light beam with a black background (50) and an optical lens (6) having an image focal plane (12) arranged in such a way as to receive the cylindrical light beam with a black background (50), to form a hollow cone light beam (60) and to focus the hollow cone light beam (60) into a point (18) in the image focal plane (12).

Abstract: The subject matter of the application is a sink accessory (e.g. a cutting board) that can be placed on a sink and a sink that is provided with a sink accessory of this type. Hereby, the periphery of the sink accessory comprises two differently spaced bearing surfaces which lie at different heights with respect to the surface of the sink accessory. In this way it is possible for one and the same sink accessory to be selectively placed on different supporting surfaces of the same sink, on the supporting surfaces of different sinks or on the supporting surface of another sink accessory (e.g. a strainer). In dependence on the geometry thereby, only the first bearing surface is in contact with the sink in a first position, whereas the second bearing surface is used as a contact area in the second position.

Abstract: The aim of the invention is to provide a method for producing a metal sheet, especially a steel sheet, at least one surface of which is provided with a surface structure that provides as structural elements depressions and/or elevations, and which metal sheet is substantially resistant to scratches and finger prints. According to the inventive method, the surface structure is configured as a random microstructure.

Abstract: A pump, such as a rotary vane pump, roller cell pump, or gear pump for delivering diesel fuel, with a pump housing and a pumping unit that is arranged in the pump housing and driven for rotation via the drive shaft of a motor. The pump housing has an intake and an outlet, and the pump further has a hand pump unit that is integrally joined to the pump housing and delivers the fuel into the intake of the pump housing and thus into the flow path of the pumping unit.

Abstract: A pump, preferably rotary vane pump, roller cell pump, or gear pump, in particular for delivering diesel fuel, with a pump housing and a pumping unit that is arranged in the pump housing and preferably driven for rotation via the drive shaft of a motor, with the pumping unit comprising an intake area, is characterized by a hand pump unit that is integrated into the pump housing and delivers on the intake side into the flow path of the pumping unit.
