Abstract: A machine for converting wind energy into electrical energy comprising in combination a housing; propellers at the forward and rearward ends of the housing mounted on shafts for rotation upon a common horizontal axis of rotation; post means supporting a central extent of the housing for rotation in a horizontal plane to face into the wind; an alternator within the housing formed of a power take off member coupled to one shaft and a rotor coupled to another shaft for counter rotating when the propellers rotate for thereby generating electricity; centrifugal pitch control mechanisms for varying the pitch of the propellers as a function of the propeller speed; transmission mechanisms for varying the speed of rotation of the rotor and power take off member as a function of the wind speed; brake mechanisms for proportionately restraining the propellers against rotation; and an aerogovernor operatively coupled with the brake mechanisms for control thereof in response to the speed of the wind as determined by the ae

Abstract: Apparatus for controlling from a remote operator station a drive means of a ground-traveling machine. A handle accessible to an operator seated at the remote operator station is moveable in a substantially T-shaped pattern. Movement of the operator handle in a line of travel defined by the stem section of the T-shaped pattern engages a clutch mechanism which connects the operator handle to a linkage arm for operating a main motion control apparatus of the drive system located at a main operator station of the machine. Upon release of the operator handle, springs bias the return of the operator handle to the home position and disengagement of the clutch mechanism. In the home position, the remote control apparatus does not interfere with operation of the main motion control apparatus from the main operator station. A safety interlock system prevents operation of the drive system of the machine at other than low speeds.
