Abstract: The invention discloses a hose coupling (100) which, on the basis of design measures, can be provided with a small number of individual components (100a, 100b, 100c) so that high reliability during operation and simple handling during coupling and decoupling are achieved. The hose coupling can in particular be locked by rotation within a small angular range, without any movable components being necessary. In some illustrative embodiments, the hose coupling (100) is used as a coupling in fluid conduits in the agricultural sector, for example in milk lines.

Abstract: A teat rubber cup comprising a head member substantially rotationally symmetric with a longitudinal axis, with an aperture for insertion of the teat, a retaining edge to engage over a teat cup sleeve, and a suction stub joined to the head member, the end of the head member opposite the teat insertion aperture merging into the retaining edge. The wall of the head member is stiffened in a region located between the teat insertion aperture and the transition to the retaining edge, and the upper end of the suction stub merges into this stiffened part of the head member. The part of the teat rubber cup head located between the stiffened part and the retaining edge is made at least partly elastic. During the suction phase a compressive force acts on the section of the head member located between the stiffened part of the head member and the retaining edge, the force endeavouring to move that section towards the outside of the suction stub. An upward movement of the teat cup sleeve then takes place, while in the relief phase a slight downward movement of the sleeve takes place relative to the teat.

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: This 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 measurement 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: An apparatus for conveying milk with the help of an underpressure in a pipe system which includes feedpipes comprises damming devices or check valves in the feedpipe, or a division of the feedpipe over at least a portion of its length into several pipes which preferably have various inside cross sectional areas and have valves which, in dependence on the milk flow rate, cause the cross sectional area of one or more pipes to be changed. In a preferred embodiment, the invention is part of a milking apparatus having milk discharge pipes which are supported overhead.

Abstract: A milk flow meter is provided, wherein the milk is tangentially introduced into an upper milk collecting chamber communicating with a milk discharge duct via a lower measuring chamber adapted to have the filling level therein measured. The milk flow meter may be suitably employed for directly measuring the milk flow during mechanized milking. Conventional flow meters are unsuitable for this purpose due to the specific properties of the medium to be measured, namely, milk, and due to the conditions of employ. The milk flow meter described enables the milk flow accurately and continuously. It is essentially characterized in that its measuring chamber communicates with the milk discharge duct via a substantially vertically extending measuring slot shielded from the remainder of the measuring chamber by a surrounding partition provided with a flow passage adjacent its lower end, and in that means is provided for measuring the retained liquid level within the partition.
