Publication number: 20230109559Abstract: A system for controlling a filling level of a reservoir filled with a liquid includes the reservoir configured to be filled with the liquid at least up to a maximum filling level. The system also includes a probe including a probe body, at least a section of the probe body extending, in a height dimension of the reservoir, from a first position to a second position, the first position being lower than the second position, and the second position being above the maximum filling level, and further including a temperature dependent sensor configured to generate a sensor signal based on a temperature at the second position, the temperature depending on the filling level. The system also includes a controller for controlling the filling level of the reservoir depending on the sensor signal such that the filling level is kept constant.Type: ApplicationFiled: September 5, 2022Publication date: April 6, 2023Inventor: Siegfried TANKI

Patent number: 8585985Abstract: An apparatus for staining sample sections, comprising: a chamber that is adapted for fastening sample sections therein; and a pump that is adapted for pumping liquids through the chamber. The chamber has an inlet and an outlet. The inlet can be connected to at least one reservoir of a staining liquid via inlet lines that are controllable by valves. The inlet lines are formed at least in the region of the associated valves by means of elastic hose lines, and the valves are formed as hose pinch valves. This apparatus minimizes or eliminates contaminations arising from staining processes for thin sections that are in particular prepared for examination in an electron microscope.Type: GrantFiled: July 21, 2008Date of Patent: November 19, 2013Assignee: Leica Mikrosysteme GmbHInventors: Reinhard Lihl, Heinz Plank, Siegfried Tanki

Patent number: 8104389Abstract: A vibrating microtome and measuring device for measuring the transverse offset of a vibrating knife comprises a light barrier into which the knife is placeable and a control application signal (pklo, pkhi) that describes the time course of the vibration of the knife and an electronic measurement system of the measuring device measures the coverage of the light barrier as an oscillating signal (tpm), and determines the transverse offset from the signal values at points in time that are defined by the control application signal.Type: GrantFiled: April 27, 2011Date of Patent: January 31, 2012Assignee: Leica Biosystems Nussloch GmbHInventors: Siegfried Tanki, Felix Redl

Publication number: 20110197731Abstract: In a vibrating microtome (1), a knife (6) is caused to vibrate during a sectioning operation in a direction parallel to a section plane and substantially parallel to the knife's edge, during which a transverse offset can occur as a consequence of a potentially present inclination of the cutting edge with respect to the section plane. A measuring device (3) for measuring the transverse offset comprises a light barrier (9) into which the cutting edge is placeable so as to partially cover the light of the light barrier. The vibrating microtome (1) generates, from the motion of the knife, a control application signal (pklo, pkhi) that describes the time course of the vibration of the knife (6), and the electronic measurement system of the measuring device (3) measures the coverage of the light barrier as a consequence of the vibration of the knife as an oscillating signal (tpm), and determines the transverse offset from the signal values at points in time that are defined by the control application signal.Type: ApplicationFiled: April 27, 2011Publication date: August 18, 2011Applicant: LEICA BIOSYSTEMS NUSSLOCH GMBHInventors: Siegfried Tanki, Felix Redl

Patent number: 7104666Abstract: A cooling chamber 10 for a microtome 1 is disclosed. A knife 2 having a cutting edge 16 is arranged in the cooling chamber 10 opposite a sample holder 4 having a sample 4a retained therein. The microtome 1 further possesses a stereomicroscope 12 having an optical system 14, the optical system 14 defining an optical axis 11. The region of the sample 4a and of the cutting edge 16 of the knife 2 is observable with the stereomicroscope 12. There is mounted in the cooling chamber 10 an illumination system 20 that emits light 20a and is directed onto a surface 2a of the knife 2 in such a way that the light 20a reflects from the surface 2a parallel to the optical axis 11.Type: GrantFiled: September 16, 2004Date of Patent: September 12, 2006Assignee: Leica Microsysteme GmbHInventors: Reinhard Lihl, Siegfried Tanki, Michael Zimmermann
