  • A RESISTOR FOR ELECTRIC HIGH-VOLTAGE APPARATUS AND A METHOD OF MOUNTING A RESISTOR
    Publication number: 20100090794
    Abstract: A resistor for electric high-voltage apparatus, especially for connection to a diverter switch in an on-load tap changer for a high-voltage transformer. The diverter switch and the resistor are arranged in a housing with transformer oil. The resistor includes a number of resistor elements, wherein each resistor element includes a resistive element, arranged in a frame, which are electrically interconnected by a connection member. The frames are designed to enclose resistive elements that include spring elements formed from spirally wound resistance wire. Connection members include a connection plug. A method of mounting a resistor for electric high-voltage apparatus.

  • Price label communication system
    Patent number: 7005962
    Abstract: Price label system comprising a price label system server connected to transceivers adapted to communicate price label information to price labels using a communication protocol. A predetermined number of transceivers defines a sub-cell and each sub-cell is associated with a communication profile that defines communication protocols to be used when communicating with the price labels in that sub-cell.

  • Price label system
    Publication number: 20040012485
    Abstract: A price label system includes a price label system server adapted to communicate with a price controlling application (PCA) server communicating price label information to price labels (PLs), wherein the characteristics of a price label depend on price label types, price label layout scripts and price label models. The system includes a price label product, being a representation of a physical price label, that links together the price label type, price label layout script and price label model for a specific price label.
