Abstract: A method for coating a rotating surface region of a workpiece by laser build-up welding includes fusing a powdery coating material prior to impact on the workpiece in a laser beam that is directed at the surface region, capturing a spatially resolved intensity profile of thermal radiation emitted by the workpiece, comparing at least one property of the intensity profile with at least one predefined target value, and modifying at least one parameter of a coating procedure based on a result of the comparison.

Abstract: Laser beam welding a workpiece includes: generating first and second beam areas on the workpiece by first and second laser beams, respectively. The beam areas are guided in a feed direction relative to the workpiece. Centroids of the beam areas are not coinciding. The first beam area runs ahead of the second beam area. A length of the first beam area, measured transversely to the feed direction, is greater than or equal to that of the second. A surface area of the first beam area is greater than that of the second. A width of the first beam area, measured in the feed direction, is greater than or equal to that of the second. A laser power of the first laser beam is greater than that of the second. The second laser beam is irradiated into a weld pool generated by the first laser beam.

Abstract: A material deposition unit includes a radiation unit designed to emit electromagnetic radiation in a directed manner onto a workpiece along a beam axis, and a powder discharge device that has multiple powder discharge units configured to discharge powder in a directed form onto the workpiece through powder-outlet openings. The material deposition unit further includes a powder division unit having multiple powder channels. A number of powder channels corresponds to a number of powder discharge units. The powder division unit is designed to distribute a central powder stream guided to a feed channel uniformly over the powder channels. Each respective powder channel is connected to a respective powder discharge unit by an exchangeable connecting element. At least one powder discharge unit has an exchangeable powder discharge element, which is elongate, has a first end and a second end, and is arranged at least partially within the corresponding powder discharge unit.

Abstract: A material deposition unit includes a radiation unit configured to emit electromagnetic radiation in a directed manner onto a workpiece along a beam axis extending in a beam direction and, and a powder discharge device having multiple powder discharge units configured to discharge powder in a directed form onto the workpiece.

Abstract: A method for displaying an attitude of an aircraft includes receiving a roll angle, a pitch angle and a yaw angle of the aircraft, generating a display image indicating the roll angle, the pitch angle and the yaw angle, and displaying the display image on a display device. The display image includes a spherical shell with a track angle scale projected onto the spherical shell along a latitude line of the spherical shell and with a pitch angle scale projected onto the spherical shell along a longitude line of the spherical shell. Furthermore, the display image includes a graphical aircraft attitude indicator inside the spherical shell rotated with respect to the spherical shell such that the graphical aircraft attitude indicator indicates the roll angle, the pitch angle and the yaw angle of the aircraft with respect to the spherical shell.

Abstract: A tractor has a front bonnet which houses an engine and a cooling arrangement, the cooling arrangement having a fan, a radiator, and a mounting plate. The bonnet has a hood and two opposing side parts. A grill is positioned at the front of the bonnet through which air passes and enters the cooling arrangement. An extended fan shroud has a lower part which extends from the bottom half of a fan ring in a forward direction and an upper part which extends rearwards from the upper half of the fan ring towards the radiator over the mounting plate. A flange extends from the lower part of the fan shroud diagonally along opposing sides of the upper part and across the upper part of the fan shroud. The flange has a sealing member. When the bonnet is closed and in contact with the sealing member, two air compartments are defined.

Abstract: A vehicle engine cooling arrangement including a fan, a radiator and a mounting plate. The plate provides a fan mounting surface and a radiator mounting surface so that the fan and radiator are in a spaced arrangement. The plate extends from under the fan at the front of the vehicle to under the radiator downstream of the fan and guides air from the fan to the radiator.

Abstract: A data glove for generating tactile feedback at a finger upon interaction of the finger with an interaction element on an infrared touchscreen includes receiving elements for receiving the fingers of an operator and stimulators for generating tactile feedback attached on the finger-receiving elements. The date glove also includes elements for identifying the finger interacting with the infrared touchscreen and a signal generator for exciting the stimulator of the interacting finger upon successful actuation of an interaction element on the infrared touchscreen.
