Abstract: A method and a device are presented with which an analysis sample of less than 50 ml can be extracted from a milk flow having an amount which is proportional, even for cows having an expected total milk amount of up to 30 kg as well as an expected maximum milk flow of 12 kg per minute. The method is characterized in that by using a valve controlled in cycles, whereby each cycle comprises a valve opening time and a valve closing time, for extracting simply an analysis sample held below a predetermined maximum amount of 50 ml from the expected value of the total milk amount to be milked from the particular cow gained from experience, a cycle time and a valve opening time are determined, whereby the cycle time and the valve opening time are respectively chosen in such a way that they lie within a predetermined range of values, that the valve opening time or the cycle time is controlled in dependence of the milk flow, and that to avoid the values of the valve opening time or the cycle time lying outwith the range of values as a result of a change in the milk flow, the valve opening time and the cycle time are changed in the same proportions to the values lying within the range. The device with which such a milk sample extraction can be carried out with, comprises a milk flow measuring device, a processor unit and a milk sample extracting device which substantially comprises an electrically controllable magnet coil with which a sealing body is moveable to a first position closing the through flow opening for the sample separating stream and a second position releasing this opening.

Abstract: A method and apparatus useful in the course of a milking operation in which the milk is intermittently conveyed in the form of separate milk slugs, to accurately determine the mass of the individual milk slugs and to thereby determine the actual milk flow rate. A measuring apparatus of this type is particularly suitable for use as an indicator operable to indicate a drop in the milk flow to below a predetermined value at the end of a milking cycle. An additional operation of measuring the travel speed of the individual milk slugs results in an extremely simple milk flow measuring device being obtained, which is capable of relatively accurately measuring the milk flow rate throughout the milking cycle.

Abstract: The specific density of the liquid/air mixture is measured at successive levels within the reception vessel for the liquid using a reference measurement (Io) representing the specific density of the degasified liquid within a reference measuring path. The ratio of each obtained density value measurement and the reference value is calculated for each measuring level and multiplied with the specific density of the liquid to allow an accurate measurment of the overall liquid volume or flow-rate. Preferably the reception vessel (1) has a respective measuring electrode (El . . . En) at each measuring level with a common counter electrode (Eo) coupled to an oscillator (4) via a constant voltage circuit (5) and a coupling capacitor (6). Each measuring electrode (El-En) is coupled via a multiplexer (7) and an active rectifier (9) to an A/D converter (10) coupled to a microprocessor (11) controlling a read-out display (12).

Abstract: A rubber teat holder for milking cups having a suction sleeve section which conically enlarges adjacent its upper edge and transforms into an enlarged holding edge for gripping over the milking cup housing. A ring lip extends radially inwardly from the holding edge toward the longitudinal axis of the suction sleeve, the inside diameter of the ring lip being smaller than the inside diameter of the conically tapering part of the suction sleeve. An annular gap is provided between the ring lip and the upper end of the suction sleeve and the annular gap is dimensioned so that the part of the ring lip which extends between the holding edge and the mouth of the suction sleeve forms a lever arm which can be loaded by alternating pressure differences between atmospheric pressure and suction pressure to render the lever arm pivotal with respect to the holding edge.
