  • Publication number: 20150114298
    Abstract: A teatcup liner, for use in a method of providing enhanced teat massage during a milking operation, includes a cross-sectional shape defining plural corner portions and plural side portions with a first side portion being a weak side and each remaining side portion being a strong side; with the weak side having a greater flexibility than each strong side such that during a collapse phase, the collapse of the weak side occurring first and being greater than the collapse of each strong side creates an asymmetric pressure distribution with a greater pressurized area resulting in a prolonged contact surface against the teat end across a first surface region of the cross-sectional shape opposite the weak side as compared to a remainder of the cross-sectional shape, the increased pressurized area across the first surface region providing an enhanced teat massage during the collapse phase.

  • Patent number: 6479017
    Abstract: A device for the measurement of an electrical parameter in the milk during the milking of an animal comprises a transportation member (1), arranged to transport the milk from a teat of said animal to a milk collecting member of a milking machine and forming a passage for the milk to be transported, and at least two electrodes (14-17) provided to be in contact with the milk flowing through the passage, and connected to an evaluation unit (18). The transportation member (1) comprises a wall member (5) provided in the passage and forming a groove (10) being open towards the passage, said electrodes (14-17) being provided on the wall member (5) in the groove (10). The wall member (5) is provided to receive a part of the milk flowing through the passage, said groove (10) being shaped in such a manner that at least a part of said received part quantity of the milk flows through the groove while contacting said electrodes (14-17).

  • Patent number: 6405672
    Abstract: In a system and a method for monitoring the physical condition of a herd of livestock, errors between values predicted in accordance with a time-series model and corresponding measured values are used for determining a confidence interval for a prediction for each animal individually the significance of an error between a prediction and a measured value regarding the likelihood that the animal is in heat or suffers from a disease is automatically assessed for each animal individually. There is no need to determine dedicated confidence intervals for different situations and properties. A better fit of the time-series model automatically results in a narrowed confidence interval.

  • Patent number: 6363585
    Abstract: A cord-locking device for releasably gripping a cord (4), which preferably may be used in a milking machine as a safety coupling. The cord comprises a grip member (12) arranged to receive the cord (4) and to hold releasably by a holding member (13). The grip member (12), held by the holding member (13), is arranged to lock fixedly the received cord (4) by clamping as a consequences of a pulling load applied to the cord (4). The grip (12), when released from said holding member (13), is arranged to enable the release of the received cord (4) from the grip member (12).

  • Patent number: 6289845
    Abstract: A milking equipment comprises a milking member (1) having teatcups (3) and a milk hose (4) connected to the milking member. A balancing device (6, 10, 11), which carries the milking member and at least a portion of the milk hose, is adjustable to an application position (FIG. 1), at which the balancing device is arranged to balance essentially the weight of the milking member and the weight of said portion of the milk hose in order to permit a milker to apply the teatcups to the teats of an animal without the need for the milker to carry the whole weight of the milking member. Furthermore, the balancing device is adjustable to a milking position, at which essentially the whole weight of the milking member acts on the teats of an animal when the teatcups are attached to the teats.
