    摘要： The invention relates to the type of device for measuring a mass flow in a harvester, where the flow is deflected at the outlet of an elevator (E) at a conveyor shaft wall (G) to form a stratified homogeneous flow and the flow is continuously measured as a function of the fill level by a capacitor (MC). The capacitor has a first capacitor plate (MC1) at a mass flow front side and a second capacitor plate (MC2) at a distance from the mass flow. The first capacitor plate is bordered and enclosed by a first protective electrode (R1) held at the same potential as the first capacitor plate by an impedance transformer. The second capacitor plate includes a portion of the conveyor shaft wall located opposite the first capacitor plate (MC1) and by lateral areas of the conveyor shaft wall. The invention improves this type of device by adding to the first protective electrode at least one partial second protective electrode (R2), where the first protective electrode (R1) extends at least partially perpendicular to the front side on the side walls of the conveyor shaft between the two capacitor plates (MC1, MC2) over at least a partial height (h1, h2) of the mass flow.

    摘要： A process and arrangement for evaluating a measurable analog electronic quantity based on the principle of the timekeeping mechanism, in which the measurable analog quantity is digitalized by counting integration processes. To exploit the simplicity and precision of the timekeeping mechanism principle also far fast and precise digital data conversion units, a deviation coding phase (AV) is inserted between the timekeeping mechanism periods (T), in which post-adjustment of the timekeeping mechanism timing ratio is possible with rapid digital circuits even in the event of abrupt fluctuations of the quantity to be measured. The invention is generally applicable for highly precise and rapid digital data conversion of analog quantities, and is especially advantageous in high-precision measuring instruments with measuring sensors in bridge circuits, for example in weighing cells based on the DMS principle in electronic balances.

    摘要： To produce a standard calibration and test element for the calibration and testing of reading and measuring instruments for bar codes and other test scales, a copper coating is applied to a ceramic substrate in a chemically depositing copper bath and degreased, and a photoresist coating is subsequently applied which is exposed through an exposure mask. This mask carries an image of the radiation-transparent and radiation-opaque regions of a pattern to be transferred onto the surface of the ceramic substrate. After removal of the mask, the photoresist coating is developed, the uncovered zones of the copper coating are etched in a metal chloride solution, and the remaining photoresist coating is removed by stripping. The uncovered, etched zones of the copper coating are dyed matt black in a metal bath. Finally, the conductive tracks are provided with a protective coating. The standard calibration and test element produced in this fashion comprises a ceramic substrate 1 as a carrier which contains a proportion of 96 to 97% of Al.sub.2 O.sub.3. The thickness of the element is 0.635 to 1.270 mm and the dimensions can extend from a 20 mm edge length to a size of 100.times. 100 mm.
