Patent number: 8581121Abstract: The disclosed embodiments describe force-transmitting devices for use in gravimetric measuring instruments. The force-transmitting devices scale the force from a calibration weight to facilitate calibration and weighing. The devices comprise unidirectional coupling elements. The unidirectional coupling element comprises coupling element parts. The elements may be adapted to transmit only a tensile force or only a compressive force to a measurement transducer. Adapting the unidirectional coupling element to transmit one type of force or the other may be done by selecting an appropriate arrangement of coupling element parts. The coupling element parts are adapted to transmit force along a midline axis by either a projection and v-shaped groove coupling or projections on the first part mated with surfaces on the second part adapted to receive and guide the first part.Type: GrantFiled: December 16, 2010Date of Patent: November 12, 2013Assignee: Mettler-Toledo AGInventors: Hans-Rudolf Burkhard, Ferdinand Schneider, Dominique Genoud

Patent number: 7851713Abstract: A parallel-guiding mechanism has a vertically movable parallel leg that carries a weighing pan. The movable parallel leg is connected by two essentially horizontal parallel guides to a stationary parallel leg installed in a balance, wherein elastic flexure pivots are formed at the ends of the parallel guides. Incisions that reduce the material strength of the parallel leg in at least one appropriate location define at least one adjustment domain, thus forming a deformation zone which is plastically deformed through application of an adjustment force. In this manner, a corner load error of the parallel-guiding mechanism is corrected.Type: GrantFiled: November 3, 2009Date of Patent: December 14, 2010Assignee: Mettler-Toledo AGInventors: Hans-Rudolf Burkhard, Dominique Genoud, Andreas Metzger, Stephan Baltisberger, Thomas Köppel

Patent number: 7829802Abstract: In a parallel-guiding mechanism, a stationary parallel leg surrounds a movable parallel leg. The movable parallel leg is connected to the stationary parallel leg and guided in vertical movement by first and second parallel-guiding elements, fastened respectively to the upper and lower end portions. The movable parallel leg can be connected to a load receiver and to a force-measuring cell through a force-transmitting connection in order to transmit the weighing load. Intermediate to, and connecting, the respective end portions is a tilt-adjustment feature, by which the end portions are tilt-adjusted relative to each other about at least one tilt axis to correct a corner load error. The tilt-adjustment feature is provided by at least one of: a pair of bending zones, a spherical joint and a ring-shaped constriction.Type: GrantFiled: November 3, 2009Date of Patent: November 9, 2010Assignee: Mettler-Toledo AGInventors: Hans-Rudolf Burkhard, Dominique Genoud, Andreas Metzger, Stephan Baltisberger, Thomas Köppel

Patent number: 7631536Abstract: The calibration weight arrangement for an electronic balance (1) with a force-measuring cell (6) has a calibration weight (14) which can be coupled to the force-measuring cell (6). A transfer mechanism and a drive source are used to move the calibration weight vertically, in order to establish, as well as to release, the force-transmitting contact between the calibration weight and the force-measuring cell. The transfer mechanism has at least one resetting element (122), a lifting system (110) configured as a knee-joint linkage (117), and a multi-stable positioning element (115). Due to the feedback from the multi-stable positioning element, whose first stable state defines the calibrating position (132) and whose second stable state defines the rest position (133) of the transfer mechanism, the actuator (118) is energized only during the phases when the transfer mechanism is moving.Type: GrantFiled: August 7, 2006Date of Patent: December 15, 2009Assignee: Mettler-Toledo AGInventors: Dominique Genoud, Thomas Köppel, Jean-Christophe Emery
