  • Method and device for determining the volumetric flow rate of milk flowing during a milking process
    Patent number: 7155971
    Abstract: The invention relates to a method and device for determining the volumetric flow rate of milk flowing during a milking process. A cross-sectional area (Ai) of the milk flow (2) is determined at a first measuring point (3) by means of a sensor (4) which is arranged outside the flowing milk. The time (ti) required by the milk flow (2) with the determined cross-sectional are (Ai), to go from the first measuring point (3) to a second measuring point (5) which is provided downstream from the first measuring point, is measured. The flow speed (vi) is derived from the measured time (ti) and the known distance (s) between the first and second measuring points (3, 5). The volumetric flow rate (V(t)) is determined on the basis of the determined cross-sectional area (Ai) and the flow speed (vi).

  • Drive system for a crop conveying device
    Publication number: 20060229119
    Abstract: In a method and a device for driving a crop conveying unit composed substantially of at least one pan with at least one sieve the pen and receive are hung in an oscillation-facilitating manner in a machine housing, at least one oscillation-reducing drive unit is provided, drive unit is formed by a linearly-oscillation unit, and the drive unit is controlled via a change in a parameter selected from the group consisting of frequency, stroke, and both.
