Abstract: A metering system for an agricultural distribution machine, a device arrangement comprising at least one flow generator for generating a conveyor airflow flowing in the conveying direction and a metering airflow, a metering device which is configured to meter distribution material using a partial metering airflow generated from the metering airflow, and a distribution system via which distribution material can be conveyed from a storage container to the metering device.

Abstract: A row unit for a sowing machine for depositing material to be distributed, comprising at least one furrow opening element which is provided to open a seed furrow; at least one depth guidance element which is provided to set a defined depositing depth and/or covering height for the material to be distributed; and at least one associated electronic evaluation device which comprises several sensors associated to the row unit, wherein the sensors are configured to scan the arable land within a detection region associated with the respective sensors, and wherein the evaluation device is configured to determine by way of the sensors the depositing depth and/or covering height of the material to be distributed that is deposited in the seed furrow.

Abstract: The invention relates to a method for controlling the lifting position of an agricultural attachment machine, such as a seeder or soil cultivation machine, during a cultivation operation on agricultural arable land.

Abstract: The invention relates to a sowing unit (10) for a precision seeder, comprising: a bracket (12); a tine share (24) arranged on the bracket (12) for producing a placement furrow for grains of seed, which furrow extends in the direction of travel, in the soil of an agricultural area; a separation device (18) arranged on the bracket (12) for separating grains of seed; a placement device (20) arranged on the bracket (12) for placing the grains of seed which have been separated by the separation device (18) into the placement furrow produced by the tine share (24); and a rolling body (26, 36, 38a, 38b) arranged on the bracket (12) for supporting the sowing unit (10) against the soil of the agricultural area and/or for depth guidance of the tine share (24).

Abstract: An agricultural working machine, in particular distribution machine, having a platform which is provided for walking on the working machine and preferably has at least one step and/or a tread, and is arranged on the working machine so as to be able to be brought into different positions and comprises at least one railing, in particular designed in the manner of a guardrail. In order to design a working machine in such a way that the platform, in particular the railing, is able to be brought particularly compactly to the working machine in the transport position, it is provided that the railing is divided at least in sections into a plurality of sections, preferably aligned at least approximately in parallel, which are pivotable, in particular foldable, in mutually repellent and/or opposite directions for lowering the railing.

Abstract: The disclosure relates to a method for operating a towed agricultural work implement (10) comprising a boom, in particular a seed drill or cultivator, comprising at least one support wheel for supporting the boom on the ground, wherein the at least one support wheel is actively controlled. The disclosure also relates to a towed agricultural work implement for carrying out this method.

Abstract: RA row unit for a sowing machine, comprising a frame, a furrow opener mounted on the frame for opening a seed furrow, a seed depositing mechanism for depositing seed into the seed furrow, and a catching roller mounted on the frame for braking and/or pressing in seed deposited into the seed furrow. In order to enable the detection of a parameter related to the sowing of seed in row units having a catching roller it is provided that a sensor carrier is arranged on the frame directly behind the catching roller in the direction of travel (F) in such a way that it is carried in the seed furrow after the seed has been braked and/or pressed in, wherein the sensor carrier has at least one sensor for detecting at least one parameter related to the sowing of seed.

Abstract: A sowing machine has row units, where each of the row units includes tillage tools and a hydraulic cylinder which applies a coulter pressure upon the tillage tools that is adjustable by a pressure valve. Further, a sensor arrangement includes at least two sensors for producing an electrical signal in connection with a total pressure acting upon the tillage tools of each row unit. In addition, an open-loop or closed-loop control device is connected to the pressure valves and the sensor arrangement and configured to adjust the coulter pressure of each row unit individually and to adapt it on the basis of the electrical signals of the sensor arrangement. In order to create a sowing machine with individual coulter pressure control that is inexpensive to manufacture, a reduced number of sensors is advantageously employed by using a functional relationship.

Abstract: A material introduction lock for a distribution machine for pneumatically conveying granular material in a conveying line adjoining a material introduction lock includes: an air inlet, a material conveying element, and a material infeed element, where a pneumatic conveying flow is supplied to the material conveying element via the air inlet, and the material infeed element is arranged between the material conveying element and the conveying line so that the granular material in the conveying line supplied via the material infeed element is conveyed in the conveying line by the pneumatic conveying flow supplied by the material conveying element. Further, the material infeed element includes a rinsing nozzle element which is connected to the air inlet and creates a film of air that sheathes the material infeed element from the inside, and the rinsing nozzle element is configured to reduce contact between the granular material and the material infeed element.

Abstract: Described are methods and compounds for diagnosis and therapy of subsets of cell proliferative disorders which are characterized by resistance to TRAIL induced apoptosis. Examples of such diseases are B-cell chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), and prostate cancer. Furthermore, methods for identifying drugs which are suitable for treatment of such diseases are described.
