  • Patent number: 7207778
    Abstract: A rotor, especially for a rotary-wing aircraft, with a rotor mast and one or more adjustable rotor blades includes a rotor blade adjustment device without a swash plate and arranged on a carrier device that automatically rotates synchronously with the rotor blades, the rotor blade adjustment device rotating along with the carrier device in a manner that is free of relative movement with respect to the carrier device as well as with respect to the rotor mast and the rotor blades. The rotor blade adjustment device includes all of the blade actuators and kinematic elements required for a synchronized, cyclic and collective rotor blade adjustment as well as a control signal interface via which the control signals for the blade actuators can be transmitted from a stationary rotor section to the rotor blade adjustment device that is rotating along. Also, a rotary-wing aircraft, especially a helicopter, including at least one such rotor.

  • Patent number: PP12169
    Abstract: A new and distinct cultivar of strawberry plant named ‘Franor’ characterized by the large single bright red-purple flowers which bloom starting from mid-May and continuing through to early November or until the first frost, bushy clumps which spread out by runners to form a carpet of foliage, its 5 or 6 flower petals which are separately formed and normally spaced, and its versatility of use for border, ground covers, in tubs, or in hanging baskets.
