  • Patent number: 11689583
    Abstract: A method performed by a network node for handling a communication session in a communication network using a session description protocol, SDP, for communication sessions is provided. The network node sends, on one or both established communication sessions, a request with an indication. The indication indicates a request of one or more mappings of a payload type number to a codec associated to the communication session. The network node receives a response including one or more response indications. A response indication indicates one or more mappings of a payload type number to a codec associated to the communication session. The network node further sends a request indication indicating a mapping of a payload type number to a codec suggested to use in an offer message generated by the at least one entity. The mapping is selected based on the one or more response indications in the received response.

  • Patent number: 9072272
    Abstract: A milking installation includes first and second fluid systems (S1; S2) and a coupling arrangement for connecting and disconnecting the first fluid system (S1) to and from the second fluid system (S2). In a connected state, the first and second fluid systems (S1, S2) are in fluid communication with one another, and in a disconnected state the first and second fluid systems (S1, S2) are not in fluid communication with one another. The coupling arrangement includes a common cavity (CC) configured to be alternately included in the first fluid system (S1) or in the second fluid system (S2) for through passage of fluid while the first and second fluid systems (S1, S2) are disconnected from one another. The first fluid system (S1) also has a by-pass arrangement configured to allow fluid in the first fluid system (S1) to circulate independently from the passage of fluid through the common cavity (CC) when the common cavity (CC) is included in the second fluid system (S2).

  • Patent number: 8327799
    Abstract: An arrangement for and method of providing a representative sample of milk from one animal, after stirring the milk, includes a receiver, milk extracting parts, a pump transferring milk from the receiver to a sample unit, a circulation line extending from the receiver via the pump and back to the receiver, for stirring the milk in the receiver. The arrangement stirs the extracted milk without injecting air into the milk, before a sample part of the milk is transferred from the receiver to the milk-sampling unit, thereby ensuring that the sampled part is representative of the milk from one animal.

  • Patent number: 8286653
    Abstract: A method is provided for eliminating the risk of leakage from a first one to a second one of two fluid systems in an apparatus for handling a fluid for human consumption, with a shut-off device including a cavity and a respective valve element connecting the cavity to each of the two fluid systems, each valve means being capable of preventing any fluid communication from the cavity to the respective fluid system. When the valve element prevents any fluid communication from the cavity to the fluid systems, a fluid is supplied to the cavity and a pressure is provided in the cavity which is higher than one or each of the respective pressures in the two fluid systems, thereby eliminating the risk of leakage from a first one to a second one of two fluid systems in case of failure of the valve element.

  • Patent number: 8191507
    Abstract: The invention relates to a solution for cleaning a milking plant, which includes a milk line system (MLS), connectable to a collecting means, and is adapted to deliver milk that has been withdrawn from animals to a milk storage means (250). The milking plant also includes milk storage valve means (100; 235, 240), arranged between the milk line system (MLS) and the milk storage means (250). The valve means (240) are selectively adjustable to prevent fluid communication between the milk line system (MLS) and the milk storage means (250) during cleaning of the milk line system (MLS). Moreover, the valve means (100; 235, 240) are associated with a monitoring arrangement (275, EPS), which is adapted to determine an amount of leakage through the valve means (100; 235, 240) during the cleaning of the milk line system (MLS), and produce a valve health status signal (Sv) reflecting the amount of leakage. Hence, the functionality status of the valve means (100; 235, 240) may be qualitatively evaluated.

  • Patent number: 8151730
    Abstract: The invention is related to a washing apparatus for cleaning milking related equipment comprising a washing apparatus connectable to an automatic milking station (2) by interconnecting pipelines in such a way as to enable the washing apparatus to circulate a washing fluid through the milking related equipment of the automatic milking station (2). The washing apparatus (6, 7) comprise a circulation tank 6 and a separate pre-filling tank (7), whereby filling in advance and holding of the washing fluid to be used in a subsequent washing step is enabled. The washing apparatus (6, 7) further comprises connecting means for connection of the pre-filling tank (7) to the circulation tank (6). By means of the invention the time needed to complete a cleaning procedure is shortened essentially, and a cleaning procedure rendered more effective. The invention further relates to such method.

  • Publication number: 20100193037
    Abstract: A method is provided for eliminating the risk of leakage from a first one to a second one of two fluid systems (123, 124) in an apparatus provided for handling a fluid for human consumption, which comprises a shut-off device including a cavity (122; 154) and a respective valve means (111, 121; 151, 152) connecting the cavity to each of the two fluid systems, each of the valve means being capable of preventing any fluid communication from the cavity to the respective fluid system. According to the method, when the valve means (111, 121; 151, 152) prevent any fluid communication from the cavity to the fluid systems, a fluid is supplied to the cavity (122; 154) and a pressure (P3) is provided in the cavity which is higher than one or each of the respective pressures (P1, P2) in the two fluid systems, thereby eliminating the risk of leakage from a first one to a second one of two fluid systems in case of failure of the valve means.
