  • Patent number: 8950358
    Abstract: A milking device for milking a dairy animal, including at least one teat cup including a flexible cup liner around a teat space, and a single pulsation space and a milk line, a milking vacuum pump connected to the milk line, for providing a milking vacuum, a pulsator connected to the pulsation space, for providing a controllable air pressure therein, and a control device for controlling at least the pulsator during at least a milking action. The control device is configured to cause the pulsator and/or the milking vacuum pump to provide, in a period of time consecutive to a milking action wherein a dairy animal is milked and a teat is located in the teat space, such a substantially stable, non-pulsating pressure difference between the pulsation space and the teat space, that the cup liner shuts off the teat space from the milk line.

  • Patent number: 8720371
    Abstract: A method of and arrangement for automatically milking an animal by use of an automatic milking system including a plurality of teat cups, a robot arm for automatic attachment of the teat cups and a control system arranged to control the milking system, wherein the teat cups are used, until a defect is established with respect to a teat cup. In that case, milking of the non-milked teat is automatically taken over by a different teat cup.

  • Publication number: 20100236484
    Abstract: A milking system includes a vacuum pump (11); milking equipment (15); a conduit (14) connecting the milking equipment to the vacuum pump; and a first vacuum regulator (25) provided to maintain a preset vacuum level in the milking equipment. A second vacuum regulator (27, 29, 30a) is arranged between the first vacuum regulator and the vacuum pump and is provided for regulating the preset vacuum to a desired level. Preferably, the second vacuum regulator includes a pressure sensor (30a) provided for measuring a pressure level in the milking system; adjustable air admitting elements (31), e.g. a solenoid valve, provided for admitting air to enter the conduit; and a control device (29) provided for controlling the second vacuum regulator depending on the measured pressure level.

  • Publication number: 20100180822
    Abstract: A milking system for extracting milk from milk producing animals and especially with elements for taking samples of the extracted milk includes in a flow direction from the animal: milk extracting elements for attachment to the animal, a milk conduit and a suction source, wherein the suction source is arranged to provide a vacuum to draw milk from the animal to a container. The milk extracting elements are adapted to provide air and milk intermittently into the milk conduit and are connected to the container via the milk conduit. The system also includes a milk sample conduit which is connected to the milk conduit. The milk conduit includes a bend for creating acceleration forces in the flow, and the sample conduit is connected to the milk conduit at the bend so as to sample milk subjected to the acceleration forces.

  • Patent number: 7758555
    Abstract: A method of treating a tissue site is provided. The method includes applying a reduced pressure to a tissue site with a reduced pressure source. A source pressure is monitored at the reduced pressure source, and a differential pressure is determined between the source pressure and the desired tissue site pressure. If a blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a first maximum differential pressure. If no blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a second maximum differential pressure.
