A stripping device for a soil compacting roller having tamping feet is described, equipped with a spar on which are provided stripper teeth and an optionally adjustable spar mount which permits readjustment of the stripper teeth on the soil compacting roller. The spar preferably comprises a pipe having a circular cross section and a spar mount and on at least one end having a pair of half shells which surround the pipe and are detachably connected for clamping the pipe in a rotationally fixed and displacement-fixed manner. This permits readjustment of the stripper teeth by a swiveling movement of the spar, which results in a large gap width for removing stripped-off soil material in a small area on which soil material can be deposited.

An object oriented framework provides a set of objects that perform warehouse control functioning and that permit a framework user to add extensions for specific processing features, thereby producing a warehouse control application program for managing the warehouse distribution system of a company. The framework includes a Product category of classes that contains product information for inventory processing, a Posting Combinations category of classes that define valid posting combinations for the general ledger, a Journals category of classes that create, process, validate, and post general ledger journals, a Bank Transactions category of classes that process bank statements, a Bank Statements and Reconciliation category of classes that reconcile bank statements with bank accounts, and a Closing category of classes that validate and close the current accounting period. These classes provide the base framework upon which an account management application program is developed by the framework user.

Calibrating a measuring cell arrangement having a diaphragm vacuum measuring cell having a programmable heater for heating the diaphragm vacuum measuring cell to a constant presettable temperature. The heater encompasses the measuring cells and is encompassed by an insulation jacket. The method includes setting a first heating temperature on the measuring cell to a constant preset value, performing a first calibration step by generating at least one preset pressure in a vacuum volume and obtaining vacuum measuring signals of the measuring cell and at least one reference measuring cell, storing pressure values in the memory, determining compensation values from the difference values of the measuring cell and the reference measuring cell, intermediately storing these difference values in a calibration data memory and gauging the measuring cell by transmitting the determined compensation values to the measuring cell data memory.

An insert structure is proposed for insertion into an orifice, a canal, a tube and the like of a human or animal creature such as an ear canal, an intestinal tract, a gullet, etc. The insert structure comprises at least one longitudinally extending insert member (3) and a plurality of at least nearly perpendicularly extending further members (5, 7, 9), placed longitudinally at a distance to each other along the insert member, the further members (5, 7, 9) being at least of a flexible and/or soft material.

In a linear ion trap, ions with two polarities are confined radially via an RF potential between the rods comprising the trap. Axially, ions of at least one polarity are confined via DC potentials applied to the elements of the trap or electrodes at the ends of the trap whereas ions of the other polarity are axially confined by a combination of pseudopotentials and/or DC potentials.

Hearing aid fitted with a central processing unit (1) having peripherals (3E, 3A) connected to its input and output respectively. Each peripheral includes an identification unit (5) having an the output connected to a first input of a comparator (9). A second input of the comparator is connected to a read-only identification memory (11) containing identification features of the peripherals. An output of the comparator drives a configuration memory (15). As a result, the hearing aid self-identifies its current configuration based on the identification of the peripherals.

The invention relates to methods and devices for regulating the filling level in measuring cells of ion cyclotron resonance mass spectrometers so that it is optimal for mass resolution and mass accuracy. The invention consists in supplying a fraction of the samples to a second reference mass spectrometer operated in parallel, and employing the mass spectra obtained from this reference mass spectrometer to regulate the filling level in the ion cyclotron resonance mass spectrometer.
