  • Patent number: 7043889
    Abstract: A harvesting machine for harvesting stalk crops, such as maize or the like, has at least two cutting and intake units which have a series of drum-like cutting and intake elements which can be rotated about essentially vertical axes and are fastened to supporting elements. It is arranged for at least one cutting and intake unit to be pivoted about a pivot axis which is positioned in the direction of travel. When the cutting and intake units are in a transporting position, the view in the direction of travel is significantly improved. This is achieved by at least two intake and cutting units being arranged so they can be pivoted in opposed directions so that one overlies the other in the transporting position and so that those on one side of the machine are spaced from those on the other side of the machine at that position.

  • Patent number: 6560953
    Abstract: A harvester at least one adapting device for receiving a front attachment, wherein a mechanically and/or hydraulically switchable reversing device is associated with at least one of the working components of the agricultural harvesting machine which are at the front in the direction of travel and the front attachment, which is received by the adapting device, can be moved by at least one displacement device into at least one non-working position which is at a distance from the working components of the agricultural harvesting machine, and which forms a gap for passage of crop between the front attachment and these working components. In this way, in the non-working position a through-gap is created between the front attachment and the working components of the harvesting machine, through which the crop stream conveyed out of the agricultural harvesting machine during the reversing process and interspersed with one or more foreign bodies can flow down in the direction of the ground.

  • Patent number: 6318056
    Abstract: An intake subassembly for an agricultural harvesting machine, in particular a self-propelled forage harvester for corn, grass and the like, including a cutting cylinder, feed rollers, and compression rollers, has a cut-out clutch for bringing the feed rollers and the compression rollers to a sudden stop. The machine may have a monitor system for detecting and processing information relating to the status and motion of the components of the subassembly and generating a signal to interrupt and brake the detected motion, for example, in response to the presence of foreign objects or overloads in the subassembly.

  • Patent number: 6119443
    Abstract: A corn harvesting attachment for attachment to a self-propelled harvesting machine such as e.g. a combine harvester is described, which can cut independently of the rows and pick the corn ears off the stalks in order to process them separately from the rest of the plants, for example thresh them out. Picking units are associated with the individual feed regions of the cutter bar, which comprise large conveying discs provided with edge recesses. The cut-off whole plants, which are picked upright, are transferred to the picking units either by means of clearing discs or by the fact that the receiving sections of the picking units enter the circle in which the conveying discs move.

  • Patent number: 5847475
    Abstract: The invention describes a method that makes it possible to correct a nonlinear relationship between the electrical phase angle and the mechanical output angle of stepper motors, using a low-resolution encoder or the like. The method of the invention makes a compromise between the conventional closed-loop control of stepper motors, which requires high resolution of angular detection, and a purely static correction of the characteristic curve. The result is a substantial improvement in synchronization, for instance when conventional claw pole stepper motors are used, as a pointer drive for a gauge in a motor vehicle. The microstep triggering is done with a corrected sinusoidal form; for the correction, coefficients that are evaluated by means of a simplified Fourier synthesis are essentially used.

  • Patent number: 5651243
    Abstract: A cutting and transporting mechanism for stalk harvesting products comprises at least one cutting disc, at least transporting disc arranged coaxially relative to the cutting disc and provided with a plurality of transporting prongs arranged on a circumference of the transporting disc, a rotatable reamer associated with the transporting prongs at a discharge location. The rotating reamer has a rotary axis located inside a circumference of the transporting disc and is driven in a direction corresponding to a direction of rotation of the transporting disc. The cutting discs carry on their outer sides catching strips extending at a flat angle .beta. to the tangent. They transport the cut product stalks radially inwardly and are inserted in depressions of the transporting discs.

  • Patent number: 5107433
    Abstract: A method inputting starting and destination points into an electronic navigation system for motor vehicles in which relevant data of street system maps comprising a street identification character and reference point coordinates with assigned house numbers, are stored in a data storage. When inputting, the street identification character and house number of the starting and destination point are entered, then the data storage is first searched for the street identification character and then for the inputted house number. When there is agreement with a house number of the reference points in the data storage its coordinates are taken over for navigation. When there is a disagreement, the reference points adjacent to it in the data storage are determined and the coordinates of the starting or destination point are determined by means of interpolation and used for navigation (FIG. 20).

  • Patent number: 5021962
    Abstract: A method for determining the north direction or the travel direction of a vehicle having an electronic compass is proposed by means of which field disturbances at the magnetometer of the compass, occurring during the navigation drive, are measured and evaluated for avoiding angle errors on the direction indication of the compass. For this purpose, the measurement values (Px, y) of the magnetometer are continuously checked by an evaluating circuit of the navigation system and with a deviation (.DELTA.x, y) of several successive measurement values past a predetermined tolerance range (A) of the locus diagram and a simultaneous angle change of the earth's magnetic field vector, an intervention is effected in the direction indication. In this connection, according to the invention, the rate of change (.DELTA..zeta.
