Abstract: The disclosure relates to a tool change system for agricultural ground cultivating machines, comprising: a ground cultivation tool, which is designed to be moved through soil for ground cultivation; a tool carrier, on which the ground cultivation tool is arranged; and a locking device; wherein the ground cultivation tool and the tool carrier together form an engagement mechanism, by means of which the ground cultivation tool and the tool carrier can be non-destructively and releasably brought into engagement with one another.

Abstract: An inter-row cultivator with a large working width, comprising a base frame with a chassis, via which the base frame is supported on the soil, and a drawbar by means of which the inter-row cultivator can be suspended on a towing vehicle; at least two tool segments, which extend transversely to the travel direction over the entire working width in a working position and which preferably extend along the travel direction in a transport position; and a plurality of hoeing assemblies which are arranged on the tool segments via a respective height guide device, preferably a remotely adjustable height guide device, wherein soil working tools paired with individual plant rows are arranged on the hoeing assemblies. The aim of the invention is to improve the care of cultivated plants.

Abstract: A method of making an electromagnetic coil for use in a high-temperature electromagnetic machine includes pre-coating magnet wire with a high-temperature insulation precursor to produce pre-coated magnet wire, winding, while applying in-situ a glass-ceramic slurry, the pre-coated magnet wire into a predetermined coil shape to produce a wet-wound green coil, and thermally processing the wet-wound green coil to produce a processed coil. In some instances, a second layer of a high-temperature insulation may be applied to the processed coil to produce a further insulated processed coil, and then thermally processing the further insulated processed coil to produce a further processed electromagnetic coil.

Abstract: A method for ascertaining an operating parameter for operating a surroundings detection system for a vehicle. The surroundings detection system includes a projection unit and an image recording unit. The method includes a step of providing a projection signal to an interface to the projection unit, the projection signal including a control parameter for projecting a light pattern into a surrounding area of the vehicle. In a step of reading in, image data are read in via an interface to the image recording unit, the image data including the light pattern projected into the surrounding area. The method furthermore includes a step of processing the image data, using a processing specification, to ascertain the operating parameter.

Abstract: A method for producing a radiation field amplifying system for amplifying a to be amplified radiation field, in particular for producing a thin disc laser amplifying system, which comprises an amplifying element with a laser active body and a cooling system for cooling said amplifying element with at least one heat sink element wherein the method comprises the step of connecting said amplifying element and said at least one heat sink element is proposed by soldering with a solder filling composition, wherein the step of soldering comprises heating up, in particular melting, said solder filling composition by exposing said solder filling composition to a soldering radiation field.
