  • Patent number: 9131643
    Abstract: A cord retainer and cord wrap system for use with a portable (e.g., handheld) electric blower, and a blower incorporating the same. The system may allow for storage of the cord onboard the blower when the latter is not in use. Embodiments of the invention may utilize a portion of the blower housing to form one winding surface for the cord. A second winding surface may be provided by a cord retainer that may be secured in place along the extension tube of the blower, e.g., via interference fit. Other embodiments may include two or more nozzles that may be selectively inserted into the extension tube to permit selective tuning of blower performance.

  • Patent number: 8080230
    Abstract: The invention relates to fine-particulate zirconium titanates or lead zirconium titanates and a method for production thereof by reaction of titanium dioxide particles with a zirconium compound or a lead and zirconium compound. The titanium dioxide particles have a BET surface of more than 50 m2/g. The lead zirconium titanates can be used for the production of microelectronic components.

  • Patent number: 7177601
    Abstract: A bimodal power data link transceiver device (33) is provided. The device comprises a transceiver integrated circuit (IC) (14); wherein the IC comprises an oscillator (150), a frequency reference port, and a RF output port. A VCO (12) is coupled to the oscillator and a direct digital synthesizer (15) is coupled to the frequency reference port. The combination allows the IC to operate below 200 MHz. In addition, an external power amplifier (19) is connected to the RF output port thus allowing for burst RF communications at a higher power than the quiescent receive mode.
