Abstract: The invention relates to a microtome, in particular a rotary microtome (1), comprising a micrometer mechanism (3) having a drive (2) for producing a relative movement between an object holder (4) and a blade and a positioning device acting on the micrometer mechanism (3) to influence the relative movement, the positioning device comprising an advancing device (6) and a trimming device (7) interacting with the advancing device (6), said microtome being designed and modified with regard to a simple and reliable adjustment of the trimming device (7) as well as activation/deactivation of a retraction by structurally simple means in such a way that the positioning device has a combined actuating device (8) for both an adjustment of the trimming device (7) and also an activation/deactivation of a retraction which can be carried out by means of the advancing device (6).

Abstract: A method for providing a piece of data in a communication system. The method includes: allocating a memory means for updating data in the memory means, in particular by a producer, in particular in response to a request signal of the producer; updating the data in the provided memory means with the piece of data; providing the memory means for the purpose of being read out, in particular by a consumer, wherein, in the allocation step, the memory means is allocated as a function of a status of the memory means.

Abstract: A steering column damper element is arranged between an outer shaft and an inner shaft and is accommodated inside the outer shaft at least in sections and coaxially. The steering column damper element is formed as an elastomer ring that has a hardness of 40 to 80 Shore and has at least one hole running axially.

Abstract: The invention relates to a device for heating an object by means of a water bath, in particular for strips of pathological or histological sections, before a microscopic examination, comprising a housing (1) and a trough (2) inserted in the housing (1), wherein the water bath is heated by means of an electrical heater, characterized in that the electrical heater comprises at least one hotplate (4) provided on the base (3) of the trough (2).

Abstract: A device for removal of excess embedding media from the surface of an embedded sample, particularly for removing wax from the outside of a tissue cassette, comprising a rack (1) and a heatable plate (2) held at an incline by the rack (1), with grooves, flutes, recesses or the like serving as drainage channels (3) being configured in the surface of the plate (2) for receiving and discharging abraded and melted embedding medium and said channels flowing into a collection channel (4), characterized in that the drainage grooves (3) each open from a highest point down outwardly on either side into collection channels (4), which lead to a catch container (5).

Abstract: A device for the processing of samples which can be cut, in particular histological tissue samples, where the device comprises a processing tray (1) with a processing surface (2) and with at least two trimming inserts (3) for laying in and cutting the samples by means of knives, is characterized by the fact that the trimming inserts (3) have an encircling edge (4), which serves for the application of the knife and for the flush cutting of the sample and that the trimming inserts (3) are embodied to have different depths for producing samples of different thicknesses.

Abstract: A motor vehicle suspension system for damping vibrations between, for example, the wheels of the motor vehicle and the body of the motor vehicle, can have a vibration damper unit with two fluid chambers therein and separated from one another by a piston unit. In addition, there can be a fluid bypass connecting the two chambers. A shut-off valve device can be disposed between two portions of the fluid connection to separate a high-pressure section and a low-pressure section, and the latter shut-off valve has a shutoff body which can be adjusted by an external control by means of a magnet armature and a magnet coil between a closed and an open position.
