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

Patent number: 9849983Abstract: An aerodynamically shaped, active towed body includes a fuselage curved along its vertical and horizontal longitudinal plane. The fuselage has a unit chamber and a load chamber. A transverse plane of the fuselage is triangular, two upper corners being located on an upper face of the fuselage and a lower corner being located on a lower face of the fuselage. Each of two wings is subdivided into a small and a large segment. The small segment points downwards and is attached to the fuselage in a region of the lower corner and the large segment points upwards and is attached to the small segment. Each of the small segments comprise an additional load chamber. The towed body further includes a tail fin, rudders that are each adjustable by the control device and a coupling for the towing cable.Type: GrantFiled: December 4, 2015Date of Patent: December 26, 2017Assignee: ALFRED-WEGENER-INSTITUT HELMHOLTZ-ZENTRUM FUER POLAR-UND MEERESFORSCHUNGInventors: Andreas Herber, Dirk Kalmbach, Ruediger Gerdes, Hans-Joerg Bayer

Patent number: 9618499Abstract: A diffusion chamber for determining different parameters of an aqueous substance includes a vertical central cylinder having a sample chamber for receiving a substance sample and a needle-shaped pH-measuring sensor having a measuring tip which is brought into contact with the substance sample. A spectrophotometer having glass-fiber optics is configured to penetrate the substance sample. A gas supply into the sample chamber is configured to provide a variable gas exposure of the substance sample when determining parameters. A needle of the pH-measuring sensor is inserted into an obliquely extending groove of a slid-in sample slide. A sealing ring on the sample slide is pressed against the central cylinder by means of an inserted spacer ring, the sample chamber is tightly sealed with respect to gases from the surroundings of the diffusion chamber, and a minimum distance is maintained between the lower collimating lens and the substance sample.Type: GrantFiled: June 21, 2014Date of Patent: April 11, 2017Assignee: ALFRED-WEGENER-INSTITUT HELMHOLTZ-ZENTRUM FUER POLAR- UND MEERESFORSCHUNGInventors: Michael Oellermann, Felix Christopher Mark, Erich Dunker

Patent number: 9151437Abstract: A stand structure includes a vertically aligned central pillar that is not connected to a subsurface and an upper bearing surface for a construction. At least three foot elements are disposed around the central pillar and configured to be connected to the subsurface. Each of the foot elements is connected to at least one upper radial strut and at least one lower radial strut. Each of the struts has a central longitudinal axis, an upper attachment to the central pillar and a lower attachment to a respective one of the foot elements. The central longitudinal axes of each of the upper radial struts has a convexly curved profile beginning at a respective one of the upper attachments. At least one tensile element is disposed so as to compensate buckling forces for each of the upper radial struts.Type: GrantFiled: February 25, 2011Date of Patent: October 6, 2015Assignee: ALFRED-WEGENER-INSTITUT HELMHOLTZ-ZENTRUM FUER POLAR-UND MEERESFORSCHUNGInventor: Christian Hamm-Dubischar

Patent number: 9019504Abstract: A transportable goniospectrometer with a constant observation center for a radiometric measurement of the reflection of a natural surface includes a spectrometer having an optical unit and a sensor. A main pillar has a lower and an upper pillar end. An arc has a fixed and a free arc end. A slide is disposed displaceably and fixably along the arc. The slide carries the optical unit orientated towards the observation center. A cantilever has a fixed cantilever end connected to the upper pillar end via a screw connection, and a free cantilever end which has a suspension that is rotatable and fixable about a vertical axis. The suspension is connected to the sensor and to the fixed arc end of the arc. The suspension is configured to position the arc at a distance of the arc radius of the arc above the natural surface.Type: GrantFiled: June 27, 2012Date of Patent: April 28, 2015Assignee: Alfred-Wegener-Institut Helmholtz- Zentrum Fuer Polar- und MeeresforschungInventors: Marcel Buchhorn, Reinhold Petereit

Patent number: 8881610Abstract: A water sampling device includes a mounting frame including two end plates disposed parallel to one another on a shaft. A multiple magazine is configured as a rotatable drum magazine that is horizontally disposed between the two end plates of the mounting frame. The multiple magazine includes a plurality of sample containers. Each of the sample containers has a first face and a second face. The first face includes a first axially arranged conical opening and a first positive locking cone forming an inlet valve. The second face includes a. second axially arranged conical opening and a second positive locking cone forming an outlet valve. Each of the positive locking ,cones is configured to shift axially relative to the respective conical opening so as to operate the respective inlet or outlet valve and so as to form a symmetrical annular gap in an open position of the respective valve.Type: GrantFiled: June 30, 2010Date of Patent: November 11, 2014Assignee: Alfred-Wegener-Institut Helmholtz-Zentrum fuer Polar- und MeeresforschungInventors: Thorben Wulff, Eberhard Sauter
