    摘要: An anode structure for a magnetron includes T-shape anode vanes having a radially extensive component and a circumferentially extensive portion, the cylindrical faces of the circumferential portion facing a cathode in the complete magnetron. The use of T-shape vanes increases inductance and hence permits low frequency radiation to be generated without increasing the dimensions of the magnetron compared to those of a conventional magnetron. Also, capacitance is increased to give a further reduction in frequency by using more than two anode straps, and preferably four anode straps at each end of the anode structure. Preferably, the anode structure is incorporated in a magnetron in which a high magnetic field of the order of 500 Gauss for a magnetron operating at 100 MHZ is used. The anode shell itself may form part of the magnetic return path. Other anode vane configuration, for example L-shaped, may be used.

    摘要: A point-to-point communications device (SS) which is capable of generating melodic alerts, each alert being generated using numeric data in a received message. The device includes a controller (36) programmed with an algorithm for dividing the digits in a decoded message into one or two digit fields. One digit fields are used respectively to determine the tempo (t) and the number of times (p) a sequence of notes is played and two digit fields are used to select notes.

    摘要: A charge electrode assembly useful in an ink jet printer comprises a nonconductive supporting structure in which a multiplicity of grooves are formed. Each groove has a conductive layer of a corrosion-resistant noble metal, preferably platinum or rhodium, thereby forming an electrode. An electric power supply is coupled to the electrodes and energizes selected ones of the electrodes when propelled ink droplets traverse the electrode area.

    摘要: A multiphase flow meter comprising two Venturis separated by a choke. The choke may be varied to adjust the properties of the multiphase fluid flow being measured. The two Venturis may be identical and may be arranged horizontally with respect to the multiphase fluid flow. The choke may be a choke in a return line of a managed pressure drilling system.

    摘要: A system and method for automatically determining library patrons' interests without having to identify the patron or otherwise invade his/her privacy based on the library patron's current use of library assets. The system and method involve categorizing the library's assets using broad mapping user interest categories, associating a user interest category with a specific library asset that is checked out, reserved or otherwise used by a library patron and providing that patron with a confirmation item containing that user interest category, providing the library patron with feedback about the library assets and the broad mapping user interest categories, allowing library patrons to access and register for a library rewards program using the user interest category number and having advertisers provide relevant information and rewards to library patrons who request such additional information.
