An agricultural harvester includes a chassis and a header carried by the chassis. The header includes: a center section supporting at least one center cutter and having a pair of lateral ends; a wing section linked to one of the lateral ends of the center section and supporting at least one wing cutter, the wing section being vertically moveable relative to the center section between a harvesting position and a transport position, the wing section being pivotable about a generally vertical pivot axis in the transport position and substantially prevented from pivoting about the pivot axis in the harvesting position; and an actuator linked to the wing section and configured to vertically move the wing section from the harvesting position to the transport position.

The invention relates to a method and an apparatus for enlarging the spectral range of an acousto-optic tunable filter by extending the operation of the transducer structure to its third harmonic. The transducer structure consists of a plurality of individual transducer elements in electrical communication through a switching network which modifies the total capacitance of the transducer structure to provide a satisfactory impedance match at both the fundamental and the third harmonic.

Method and apparatus for the spectral range enlargement of acousto-optic

An acousto-optic Q-switch consisting of an acoustic transducer and an acoustic absorber affixed in opposing relationship with a portion of a laser medium having a relatively high figure of merit, M, disposed therebetween, provides an integral structural combination for the function of the laser medium and Q-switch which avoids the resonating wave power losses, and eliminates the problem of reflection and alignment encountered in laser systems employing acousto-optic Q-switching devices which are separate and spaced apart from the laser medium.
