Abstract: The present invention relates to a method for automatic separation of foremilk and/or milk not suitable for consumption from the milk line system of a milking plant and an apparatus for carrying out said method. A separating device (44) is arranged at the ends of a milk line (52) and a test milk line (56), said milk lines being parallel. The separating device is designed with a damper means (48) attached to a cup (46). When milk is fed through the outlet (16), the cup (46) is filled up and its weight pivots the separating device from a first position, in which the inlet to a milk line (52) is closed by means of the damper mean, to a second position, in which the milk in cup is poured into a test milk line (56) and the damper means is lifted off the inlet (50|) to the milk line (52).

Abstract: A transponder for, for example, domestic animals can receive high frequency energy and transmit information of an antenna (L.sub.x, L.sub.y, L.sub.z) and has a storage capacitor (C.sub.5) for storing received energy, which is used for transmitting on the antenna. In order to make the antenna less sensitive to the geometric direction of the received high frequency energy, it has a plurality of antenna coils (L.sub.x, L.sub.y, L.sub.z), that are arranged in an angle to each other, e.g. perpendicularly to each other. Monitoring circuits (LD.sub.x, LD.sub.y, LD.sub.z, 1) can detect the energy received on each coil and compare the detected values to each other and can, for issuing information, use that coil on which the largest energy has been received. Thereby, the transmission can be made in a direction which is considerably more optimal than a direction which otherwise would be obtained in a more random fashion.

The processor (7) receives signals from a motion sensor (15) and is coupled to a transmitter (11) having an antenna (13) and can activate the transmitter (11) for transmitting radio signals having a good range, when the motion detector (15) signals an increased activity, such as for a non-milking cow during the estrus period.

Abstract: The invention concerns an aqueous suspension of a non-ionic, water-soluble cellulose ether cross-linked with glyoxal, in the presence of an electrolytic salt which gives a pH value below 8.0 in water and at the concentration involved. Conveniently, the suspension is produced by mixing the water included with a dry blend containing the cellulose ether and the electrolytic salt, and preferably the other components of the suspension as well.

Abstract: In a method of producing a suspension of a nonionic cellulose ether that has no turbidity point, the water forming part of the suspension is mixed with a dry mixture containing a cellulose ether, which is cross-linked with glyoxal, and an electrolyte salt. This electrolyte salt consists of a salt of a mixture of salts which, in water and at the concentration employed, results in a pH value below 8.0. Preferably, the cellulose ether is a hydroxyethylcellulose.

Abstract: A reflux valve means for a fluid conduit (30) having a fluid outflow end, wherein the valve means includes a vacuum valve (10) intended for connection to a conduit branch (18) preferably to a top part or rising gradient of the conduit upstream of its outlet end. The valve (10) includes a valve housing (15, 16) provided with a passageway (20, 17, 19) which establishes communication between the atmosphere surrounding the valve and the conduit branch (18). The passageway includes a valve seat (12) and a valve plate (11) which can be moved into and out of sealing contact with the seat (12) under the influence of conduit pressure that is higher than atmospheric pressure. The valve plate (11) of the vacuum valve is constructed to be deformable elastically into and out of a generally dish shape when the valve is closed, under the influence of those pressure variations that normally occur in the fluid in the conduit branch.

Abstract: The present invention relates to a method for measuring conductivity, in particular for use in liquid chromatography systems, and to a device for performing such measurement. In one aspect it provides a method of measuring conductivity in liquids, comprising applying an AC voltage over a conductivity measurement cell. In response to a conductance value calculated from the output of the cell, an expected frequency of the AC voltage is generated. The AC voltage frequency is set to the calculated value. The above steps are repeated until two consecutive conductance determinations differ by only a predetermined absolute value. Then the value may be displayed and registered as the true conductance value of the sample.
