Abstract: A pipette device has a coupling stud on which a pipette tip can be stuck in a slipping-on direction for coupling. The coupling stud has an adjustable prestress member that can be adjusted into a prestress state and a release state via an actuation device which is provided in the coupling stud. The pipette tip has an axial stop which interacts with a counter-stop of the coupling stud in an axial coupling position of the pipette tip. The prestress member in its prestress state acts upon a working surface of the stuck-on pipette tip having a surface component of the pipette tip, which extends radially inward, turned away from the stuck on direction, in such a way that it abuts sealingly on the working surface, and prestresses the pipette tip on the pipette unit into the axial coupling position. The prestress member, in its releasing state, substantially releases the working surface of the pipette tip (101).

The coupling stud has an adjustable pre-stress member that can be adjusted into a prestress state and a release state via an actuation device which is provided in the coupling stud.

Abstract: The invention relates to a method for evaluating a liquid dosing process in a container which is at least partially filled with a gas. According to the inventive method, a temporal course of at least one state variable p of a medium contained in said container is determined essentially over the entire duration of the dosing process. The temporal course (40; 40?) of the at least one state variable (p) is graphically or mathematically compared with a pre-determined state variable nominal range (42; 42?; 242) by means of a correlation method, and an evaluation result (S6, S14, S16) is obtained according to the results of the comparison.

According to the inventive method, a temporal course of at least one state variable p of a medium contained in said container is determined essentially over the entire duration of the dosing process. The temporal course (40; 40′) of the at least one state variable (p) is graphically or mathematically compared with a pre-determined state variable nominal range (42; 42′; 242) by means of a correlation method, and an evaluation result (S6, S14, S16) is obtained according to the results of the comparison.

Abstract: A maximum density mobile storage system in which groups of racks or other storage devices are arranged side by side in a row or bay along side a loading and unloading aisle or corridor, the individual racks being selectively movable individually or in groups so as to leave a loading or unloading space between any two of the racks, whereby the length of the bay need exceed the sum of the widths of the racks by an amount which equals the width of the desired gap, particularly characterized in that the width of the gap can be varied simply by altering the position of end stops which determine the overall limits of travel of the racks; any moving rack can be stopped at any point at any time therefore enabling the establishment of multiple gaps; the racks are individually motored and the controls are such that when the system is placed in motion the racks remain in motion until all gaps in the moving direction have been filled or closed; individual controls can be carried by the associated racks or centrally posit
