    Abstract: A device is provided for scanning the field of view of an optical instrument. The device includes a housing for connection to the optical instrument and a scanning means which has freedom to move in any direction to cover the area of an aperture in the housing which communicates with the optical instrument. Holding means releasably fix the position of the scanning means with relation to any given portion of the aperture and, therefore, the field of view. Interchangeable optical means may be mounted on the scanning means to increase the magnification of the area viewed.

    Abstract: A ROTARY WING SYSTEM FOR AIRCRAFT WHICH COMPRISES A RATATABLY MOUNTED HUB, AND A PLURALITY OF BLADES EACH CONNECTED TO THE HUB FOR ROTATION THEREWITH BY A RESPECTIVE BALL JOINT TO PERMIT MOVEMENT ABOUT THREE COORDINATE AXES INCLUDING THE LONGITUDINAL AXIS OF THE BLADE. BLADE PITCH CONTROL MEANS ROTATABLE WITH THE HUB IS CONNECTED TO THE BLADES TO HOLD EACH BLADE IN PREDETERMINED POSITION WITH RESPECT TO ITS LONGITUDINAL AXIS AS THE BLADES ARE ROTATED. THE BLADE PITCH CONTROL MEANS IS LONGITUDINALLY SPACED FROM THE HUB AND MOUNTED FOR RECIPROCABLE MOVEMENT IN A PLANE PARALLEL TO THE LONGITUDINAL AXIS OF THE HUB. THE BLADE PITCH CONTROL MEANS INCLUDES A LINKAGE CONNECTED TO EACH BLADE AT A POINT SPACED FROM THE BLADE''S BALL JOINT CONNECTION TO THE HUB AND SPACED FROM THE LONGITUDINAL AXIS OF THE BLADE.
