  • Publication number: 20220285070
    Abstract: A sialic electric induction system is provided. The static electric induction system includes a heat generating electric component; a dielectric cooling fluid; a cooling passage structure along the electric component; and a pump arrangement arranged to alternatingly be controlled in a first mode and in a second mode. In the first mode, the pump arrangement pumps the dielectric cooling fluid to be driven through the cooling passage structure in a forward direction to cool the electric component, and in the second mode, the pump arrangement pumps the dielectric cooling fluid to be driven through the cooling passage structure in a reverse direction, opposite to the forward direction, to cool the electric component. A method of controlling a static electric induction system is also provided.

  • Publication number: 20140327506
    Abstract: An oil transformer includes a transformer vessel, a transformer core mounted in the vessel, at least one upright hollow cylindrical transformer coil including at least one axial cooling channel arranged around a limb of the transformer core, and an oil chamber arranged at an axial front side of the transformer coil. At least one first opening leading from the inner chamber to the belonging front side of the transformer coil is provided, and at least one second opening is provided within the surrounding boundaries of the oil chamber. The oil chamber is an under-pressure chamber, wherein the at least one first opening is an inlet port and the at least one second opening is an outlet port.

  • Patent number: 7769826
    Abstract: Systems and methods of determining DNS information, such as an IP address, associated with a domain name. The methods using a cache segregated to store various domain name system (DNS) data in different data structures. The data structures are configured for minimization of data retrieval times. In some embodiments, answer information is stored in a hash table. In these and other embodiments, times required to search for answers are essentially constant as a function of the number of labels comprising the domain name.

  • Publication number: 20020065085
    Abstract: The present invention comprises a system and method for positioning a mobile station within an AMPS/TDMA system. Upon receipt of a positioning request for the mobile station at a positioning node, a positioning request indicator is transmitted to an MSC of the mobile station within a first group of ANSI-41 messages. The positioning data is determined for the mobile station responsive to the positioning request indicator and transmitted back to the positioning node using a second group of ANSI-41 messages.
