Abstract: The invention relates to a moisture measuring device and a method for measuring moisture of the crop material in harvesting machines. To improve the moisture measurement, the combination of the moisture measuring device with a sensor state monitoring device ensures that the manual calibration effort is reduced. According to the method disclosed in the present invention, the correction value from the measured moisture value is at least, in part, a function of the working condition of the harvesting machine.

Abstract: A device on a mobile agricultural machine for contactless scanning of contours extending over the ground, such as the contour of a swath of crop material. In this case there is used a laser distance measuring device consisting of a laser beam transmitting and receiving device which determines the distance from a contour point by measuring the running time of a laser scanning beam emitted and reflected at the contour point. The laser scanning beams are pivoted within a certain angular range stepwise or continuously in a scanning beam plane. In this case the laser distance measuring device is mounted with an orientation on the agricultural machinery such that the scanning beam plane is inclined to the ground at an acute angle forwards in the direction of travel. With the aid of an analyzer, the position of the contour point corresponding to each pivot angle, based upon the measured distance and the arrangement and orientation of the laser distance measuring device on the agricultural machine, can be determined.

Abstract: The invention describes a device and a method for finding an actual or a virtual reference point on mobile equipment or implement. In agricultural technology the control and mapping of working processes as a function of the instantaneous position of the equipment on the field is gaining more and more importance. With increasing precision of the navigation systems, further possible applications are opening up. As a result of the higher precision of satellite navigation systems, the changes in inclination and direction of the equipment also have an effect on the measured position of the equipment. This effect is of the order of magnitude of the precision of modern-day navigation equipment and is therefore also taken into consideration in position finding according to the invention. For this the inclinations and direction of the machine referred to a predefined neutral position are determined and also calculated when finding any reference position.

Abstract: A harvesting machine, such as a combine, has a number of laterally equispaced, side by side, rotatable augers (14) extending in a forward direction, each auger having a rotatable auger shaft (16) which is included upwardly towards the rear and an auger flight on the shaft.

Inclined slots (28) are also provided which extend rearwardly from respective slot entrances at the forward end of the header, the slots being sufficiently wide to allow passage of stalks of material to be harvested but too narrow to allow passage of crop ears or other material to be collected so that the crop ears or other material to be collected can be stripped from the stalks by the action of the slots during forward movement of the header. The augers are rotated by a drive.

Abstract: The invention relates to an operating method of an internal combustion engine. According to the method, a fuel-air mixture is rapidly combusted in order to move a piston. The fuel contained in or introduced into an occluded fresh gas is evaporated in the fresh gas, which has already been sucked into a cylinder chamber and then compressed. The fuel is then combusted and the piston is subjected to the pressure produced by the combustion gases (working cycle). After performing its working cycle, the piston ejects the waste gases from the cylinder chamber. The aim of the invention is to improve the efficiency of the internal combustion engine. To this end, the fresh gas that is compressed during the compression cycle is pressed into a first combustion chamber. The aforementioned evaporation process is then carried out in the first combustion chamber once it has been sealed off from the cylinder chamber.

Abstract: A toothed selector clutch is provided to operate in a hydrostatic/mechanical, split-torque power-shift transmission comprising a four-shaft epicyclic-gearwheel transmission and an infinitely variable hydrostatic transmission arranged in parallel. The selector clutch is associated with a particular gearwheel stage and is operated to select a particular gear. Gear changes take place at synchronous speeds without loading the engaging gear during the change and without interruption of the transmission of torque from the rotating shaft to the gear being disengaged. The toothed selector clutch is a coaxial double differential clutch with a clutch carrier that is arranged in a rotationally and axially fixed manner on a clutch shaft. A double piston, which can be subjected to a pressure medium on both sides, is provided as a shift bridge and is operatively connected to the clutch carrier by toothing thereby permitting torque transmission and axial displacement.

Abstract: A manufacturing process for establishing optimal operating limits, which are a percentage of a specified or blue-print tolerance, for the critical characteristics of manufactured products. The process begins a selection step for establishing an operating range based upon a percentage of tolerance for the critical characteristics of the manufactured product. The next step of the process is the manufacturing step including; making a determination as to whether the manufacturing apparatus is capable of operating within the proposed operating range, evaluating the fitness of the materials, manufacturing the products within the proposed operating range, and measuring the critical characteristics of the manufactured products. The process is audited to verify that product critical characteristics are maintained within the operating range. Any products whose critical characteristics are not within the operating range is rejected and is not offered for sale to customers in the relevant market.
