Patent number: 12000761Abstract: An emergency shower test device for testing an emergency shower includes: a collection container; an inlet pipe, which has at an upper end thereof a receiving section for a head of the emergency shower, which opens at a lower end thereof into the collection container and which is vertically adjustable by a lockable adjusting device, the inlet pipe being largely retractable into the collection container; a drainage system arranged in a lower region of the collection container for emptying the collection container; and a frame in which the collection container is arranged in an elevated position. The receiving section of the inlet pipe is integrated into the upper end of the inlet pipe. The inlet pipe has a constant diameter for fully accommodating the head of the emergency shower, the adjusting device including a reversed rope with a counterweight adapted to a weight of the inlet pipe.Type: GrantFiled: February 12, 2021Date of Patent: June 4, 2024Assignee: ALFRED-WEGENER-INSTITUT, HELMHOLTZ-ZENTRUM FUER POLAR—UND MEERESFORSCHUNGInventors: Thore Bochert, Johannes Lemburg

Patent number: 11027947Abstract: A load-force-independent triggering device for a load exerting a force on it that is held in a CLOSED position of the triggering device and released in an OPEN position of the triggering device includes: a housing; a triggering lever, which is connected to a triggering gear via a steering lever, the triggering lever being swivel-mounted on a first housing axis, the triggering gear being swivel-mounted on a second housing axis and the steering lever being swivel-mounted on a steering-lever axis on the triggering lever and on a second steering-lever axis on the triggering gear; a spring device acting on the triggering lever; and a locking device, by which the triggering device is fixed in the CLOSED position. The steering lever has an angular design, and, in the CLOSED position of the triggering device, contacts a first contact surface in the housing.Type: GrantFiled: December 7, 2018Date of Patent: June 8, 2021Assignee: ALFRED-WEGENER-INSTITUT, HELMHOLTZ-ZENTRUM FUER POLAR- UND MEERESFORSCHUNGInventor: Johannes Lemburg

Patent number: 10393630Abstract: An automated multiple-sample processor for fluid samples includes a plurality of piston pumps which have a sample opening, a cylindrical housing and an axially displaceable piston and which are removably mounted in a support frame. The two spiral springs are both designed either as extension springs or as compression springs. In the case the two spiral springs are provided as the extension springs with a release lever in a first installation position, the triggering of the release lever results in the piston being pushed into the cylindrical housing. In the case the two spiral springs are provided as the compression springs with the release lever in a second installation position, which is rotated by 180° with respect to the first installation position, the triggering of the release lever results in the piston being pushed out of the cylindrical housing.Type: GrantFiled: April 11, 2017Date of Patent: August 27, 2019Assignee: ALFRED-WEGENER-INSTITUT HELMHOLTZ-ZENTRUM FUER POLAR-UND MEERESFORSCHUNGInventors: Johannes Lemburg, Erich Dunker

Publication number: 20110026356Abstract: The invention relates to an apparatus for the uniform distribution of microparticles in a liquid, said apparatus comprising a storage chamber 1 including a suspension of microparticles and liquid, a mixing head 2 for receiving the suspension, and a pump 3 which is connected to the storage chamber 1 and the mixing head 2 for sucking the suspension from the storage chamber 1 into the mixing head 2, said mixing head 2 having at least one well 4 with a flow turbulator 5 and an overflow 6 which is connected to the storage chamber 1 via an opening 7, characterized in that the storage chamber 1 has a pin 14 and/or a rotary inlet 15 and a rotary runback 16 which are connected to the pump 3. The apparatus can be used for the identification, characterization and purification of proteins. The invention is also directed to a method for the uniform distribution of microparticles in a liquid, which method generates a turbulent, quasi-static state.Type: ApplicationFiled: September 26, 2008Publication date: February 3, 2011Applicant: CHARITÉ - UNIVERSITÄTSMEDIZIN BERLINInventors: Jörg Feldhusen, Hartmut Schlüter, Joachim Thiemann, Johannes Lemburg
