Abstract: A crop harvesting header includes a reel for controlling movement of the crop in the area over the cutter bar to the transport draper carried on two reel mounting arms for upward and downward movement and for moving the reel forwardly and rearwardly along the respective reel mounting arm. The reel has a plurality of reel bats with reel fingers projecting generally radially outwardly from the reel axis where the reel bats are pivotal to vary the angle of the finger driven by a cam track member. An adjustment component defined by a follower in a guide track along one of the arms is responsive to movement of the reel along the arm which causes the cam track member to be angularly advanced and retarded about the reel axis to different adjustment angles in dependence upon the position of the reel along the mounting arms.

Abstract: A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

Abstract: A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

Abstract: In a crop harvesting machine there is provided a pair of hydraulic float cylinders or springs for a header such as a rotary mower relative to a self-propelled vehicle, where a float spring force is controlled to provide a predetermined lifting force is provided to the header. The spring force is varied in response to detection of ground speed to decrease the lifting force at higher ground speeds. A position sensor is used to generate an indication of movement and/or acceleration. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. In order to reduce static friction so that the system can react quickly, an arrangement is provided for causing relative reciprocating movement in an alternating wave pattern between the piston and cylinder.

Abstract: In a crop harvesting header with a center section and two wings where each wing is pivotal relative to the center section about a pivot axis extending in a generally forward direction which includes a balance system to maintain a balanced ground force distribution across the width of the header there is provided an automatic adjustment system for maintaining proper balance. The system includes angle or other sensors which detect the pivot angle of the wing section. This can be used in a static testing system where the position to set to a detected midpoint and/or in a dynamic system where repeatedly, over a time period during which the header is operating, data is detected relating to the positions of each wing frame portion.

Abstract: The patient interface may comprise an axis for alignment with an axis of the eye such as an optical axis of the eye. The interface may comprise a guide to allow the interface to move along the axis with the eye, which can inhibit increases in intraocular pressure when the patient is aligned with the laser. The interface may comprise a lock to hold the patient interface at a location along the axis, which can maintain alignment of the patient with the laser eye surgery system. The interface may comprise a plurality of transducers to measure forces to the eye during surgery. The laser eye surgery system can be configured in one or more of many ways to respond to the measured forces. For example, the system may offset the position of laser beam pulses to increase the accuracy of the placement of the beam pulses on the eye.
