The present invention relates to an applicator (10) for ejecting doses of a flowable component, comprising- a housing (12),- an application tip (14) connected to the housing (12),- an actuation mechanism (26, 30), and- an insert (18) which is detachable from the housing (12), the insert (18) being adapted to be inserted into the housing (12), the insert (18) having a storage volume (36) for the flowable component, wherein the housing (12) comprises a receiving portion (19) adapted to the insert (18). The applicator is characterized in that the insert (18) comprises a drive portion (32) which is adapted to cooperate with the actuation mechanism (26, 30) so that the operation of the actuation mechanism (26, 30) results in a displacement of the insert (18) relative to the housing (12) and on a displacement axis (D).


The present invention relates to a pump (10) for fluids, said pump comprising: a pump housing (11); a power source (8) enclosed within said housing (11); a drive shaft connected to the power source (8); at least one pump inlet (14) arranged in the pump housing; a pump outlet(15) arranged in the pump housing; a first impeller (24) arranged within a first impeller chamber (25) and rotated by said drive shaft, and a second impeller (19) arranged within a second impeller chamber (20) and rotated by said drive shaft. The pump is changeable between a first configuration in which the first and second impeller are arranged in parallel to provide a high pumping capacity, and a second configuration in which the first and second impeller are arranged in series to provide a pump with less pumping capacity. The invention furthermore relates to a method for changing the pumping capacity of a pump (10) comprising a first impeller (24) and a second impeller (19).


The present invention relates to a packing element for a structured packing including at least two adjacent corrugated sheets, wherein each of the corrugated sheets comprises a plurality of alternately oriented peaks and troughs, wherein adjacent corrugated sheets are oriented such that the corrugations of the adjacent corrugated sheets intersect in crisscross fashion with the corrugations of the corrugated sheets extending obliquely relative to the vertical direction, wherein each corrugated sheet contacts each of the adjacent corrugated sheets at points of intersection between the corrugations of the corrugated sheet and those of the adjacent corrugated sheets, wherein all corrugated sheets are tied together by means of at least one rod, wherein the at least one rod penetrates the corrugated sheets perpendicularly to the longitudinal section of the corrugated sheets, wherein on the at least one rod before the first corrugated sheet of the packing element and/or after the last corrugated sheet of the packing element at least one mounting clip is provided for fixing the corrugated sheets on the rod, wherein the mounting clip comprises a central part forming a coupling portion for coupling the mounting clip to the rod and two opposing lateral parts forming a clamping portion for a clamping engagement with the corrugated sheet, wherein the lateral parts are connected with the central part and angled with respect to the central part.


The present invention relates to a static mixer for mixing together at least two components comprising: a mixer housing (12); a mixing element (16) arranged at least partly within the mixer housing (12); and a mixer inlet section (14) having at least two inlets (18a, 18b) provided at an input side and at least two outlets (22a, 22b) provided at an output surface (32). The mixer housing (12), the mixing element (16) and the mixer inlet section (14) are formed as separate elements. The mixing element (16) comprises a plug element (30) and the mixer inlet section (14) comprises a counter plug element (26) engaging the plug element (30), and the mixing element (16) and the mixer inlet section (14) are plugged together in a rotationally fixed manner by means of a plugged connection. The invention further relates to a dispensing apparatus, to a method of assembling a static mixer, and to a use of a static mixer or a dispensing apparatus.


The invention relates to a method for filling a cartridge (16) with a flowable component (28), the method comprising the steps of:- providing a cartridge (16) with a cartridge chamber (18), the cartridge (16) having a piston (20) arranged in the cartridge chamber (18, the cartridge chamber and the piston defining a storage volume (30), the piston having a through-hole (22),- arranging a filling nozzle (14) at the through-hole (22) and- filling the cartridge (16) by dispensing the flowable component (28) through the through-hole (22) of the piston (20) into the storage volume (30). The invention further relates to a system suitable for executing the method.
