Publication number: 20230405836Abstract: A rotary gripper having two gripping jaws and an actuating mechanism displaceable along a displacement path and rotatable about a rotational axis. The gripping jaws are displaced and/or swiveled during displacement of the actuating mechanism and rotation of the actuating mechanism leads to joint rotation of the gripping jaws about the rotational axis. The rotary gripper has a magnet, a magnetic field sensor and a processing device. The magnet is attached to the actuating mechanism so that a magnetizing direction runs at an angle to the rotational axis. The magnetic field sensor is arranged to detect the magnetic field of the magnet and to detect components of the magnetic flux density of the magnetic field for at least two spatial directions. The processing device is set up, depending on the components of the magnetic flux density detected, to detect rotational information relating to a rotational angle of the joint rotation of the gripping jaws and gripping information relating to the gripping position.Type: ApplicationFiled: June 20, 2023Publication date: December 21, 2023Inventors: Friedrich DURAND, Tobias FRASCH, Ramon FELDER, Steffen SCHÜTZ

Patent number: 10350516Abstract: A blood filtering device has a tubular housing with a tubular section and tubular housing volume. A filtration section with a filter medium separating a raw side from a clean side is arranged in the tubular housing. The filtration section is movable along the tubular section and movably sealed relative to the tubular housing. The filtration section separates the tubular housing volume into variable first and second tubular housing volumes. A first communication path extends between raw side and first tubular housing volume. A second communication path exits between raw side and second tubular housing volume. When moving the filtration section, blood in the first tubular housing volume flows through the first communication path to the raw side; blood plasma passes through the filter medium to the clean side; residual blood flows through the second communication path into the variable second tubular housing volume.Type: GrantFiled: December 28, 2015Date of Patent: July 16, 2019Assignee: MANN+HUMMEL GmbHInventors: Dagmar Winkler, Heike Rupp, Steffen Schuetz, Karlheinz Muenkel, Joachim Stinzendoerfer

Publication number: 20160228968Abstract: The invention relates to an arrangement of at least two solder-wettable separating strips (6, 7) for a soldering nozzle, for simultaneous wave soldering of rows of soldering points, said rows being arranged so as to be spaced apart. The invention is distinguished by the fact that the depth of the separating strips (6, 7), along the solder influx direction, amounts to at least a multiple of the thickness of the separating strips (6, 7), in order to carry away excess solder from the soldering points by means of surface tension by transfer to the separating strips (6, 7); and also by the fact that the at least two separating strips (6, 7) are oriented exactly parallel to one another and are connected fixedly as a group of separating strips (6, 7) to form a strip assembly (2). The invention makes it possible to carry out wave soldering with a repeatably high quality and also without the formation of solder bridges even in the case of circuit board structures with a very fine pitch.Type: ApplicationFiled: June 30, 2014Publication date: August 11, 2016Inventors: Steffen Schütz, Simon Hame, Thomas Huhler
