摘要： An apparatus and method are provided for laser deposition welding of powdery welding material. The powdery welding material is conveyed via a nozzle coaxial with respect to a laser beam directed in a focused manner with a constant focal length onto a processing region through the nozzle onto the processing region. Optical elements are arranged in a laser optical unit for the shaping and guidance of the laser beam. The laser optical unit is attached to a processing head and can be moved with the processing head parallel to the laser beam by a first drive. The plane of the focal point can thereby be changed with respect to the surface. The nozzle can be moved independently of the laser optical unit parallel to the optical axis of the laser beam by a second drive.

摘要： An apparatus and method are provided for the laser deposition welding of powdery welding material having increased flexibility and reduced costs, in particular for systems engineering. The powdery welding material is conveyed via a nozzle coaxial with respect to a laser beam directed in a focused manner with a constant focal length onto a processing region of a workpiece through the nozzle onto the processing region. A plurality of optical elements are statically arranged in a laser optical unit for the shaping and beam guidance of the laser beam. The laser optical unit it attached to a processing head and can be moved with the processing head parallel to the optical axis of the laser beam by a first drive. The plane of the focal point can thereby be changed with respect to the workpiece surface and to the size of the surface of the focal point in the processing region. The nozzle can be moved independently of the laser optical unit parallel to the optical axis of the laser beam by a second drive.

摘要： A system to adjust to the changing draft of ocean-going ships on the aft seal system equipped with several outwardly-directed gaskets and one inwardly-directed gasket, in which, between each two outwardly-directed gaskets a ring-shaped chamber is reserved, to which a feed line for compressed air is connected. Integrated into the feed line is a pressure control mechanism and a discharge channel which can periodically empty into the interior of the ship (bilge), whereby the pressure in the ring-shaped chamber is always maintained slightly below the outside water pressure. The system is characterized by the fact that an electronic draft measurement system is located on the ship's hull to supply electric signals which correspond to the current draft, which signals actuate the pressure control mechanism. In addition, for the lubrication system, there are two pressure control mechanisms pressurized by compressed air, and which are also actuated by the signals of the draft measurement system, whereby these pressure control mechanisms are each connected to the gas cushion of their own externally airtight containers which are pressurized with lubricant and in which a specified level is maintained, whereby the one container empties into a ring-shaped chamber between the inwardly-directed gasket and the outwardly-directed gasket, and the other container empties into the lubricant chamber.

摘要： A safety device on an aft seal system equipped with at least two gaskets for a ship's propeller shaft, which propeller shaft is sealed with respect to the outside water and with respect to a lubricant chamber, and on which a ring-shaped chamber is reserved between each two gaskets, to which chamber are connected a feed line for compressed air and a discharge channel which can be emptied by means of a solenoid valve which opens and closes periodically. The pressure in the ring-shaped chamber is kept always slightly lower than the respective outside water pressure and the lubricant pressure by means of a pressure regulation mechanism. In the feed line to the ring-shaped chamber, downstream of the pressure regulation mechanism there is a solenoid valve, and downstream of that there is an airtight container with a float switch, whereby when the container is full of fluid due to a clogging of the discharge channel, the solenoid valve closes and thereby protects the pressure regulation mechanism and the other units against flooding.
