  • Process and apparatus for the free-forming manufacture of three dimensional components of predetermined shape
    Patent number: 5649277
    Abstract: An apparatus and process for the free-forming manufacture of three-dimensal components. A powder-binder mixture, or a material with a high melting point, is plasticized or made molten, by raising the temperature inside a process chamber. The resulting molten material is discharged under pressure through a nozzle which is arranged at the end of the process chamber. The material inside the process chamber is deposited in layers. The processing direction and processing speed of the nozzle are programmed. An embodiment of the invention is disclosed in which a non-molten powder is deposited and supported by the deposition of a second powder alongside the non-molten powder.

  • Method for the determination of a geometrical parameter for crimped, irregularly structured fibres
    Patent number: 4835605
    Abstract: The invention relates to a method for determining a parameter for fibres, particularly for crimped, irregularly structured fibres, such as textile fibres and tobacco fibres. A given quantity of fibres is separated on a substrate. Two congruent images of the separated fibres is produced with a camera. By means of a grid, the number of grid elements covered by the fibres is determined from the superimposed congruent images. The images are then mutually displaced by one and/or more grid steps (.DELTA.x.sub.o,.DELTA.y.sub.o) in (-x) and (+y) and (x/.+-.y) (diagonally). (For symmetry reasons the (-x) and (-y) displacements give the same results as the (+x), (+y) displacements and the (-x/.+-.y) displacements give the same results as the (+x/.+-.y) displacements. The number of grid elements with fibres of the two images still covering one another following the displacement is determined and added to the number of grid elements with fibres of the non-displaced images.

  • Blowdown device for steam power plants
    Patent number: 4399082
    Abstract: Blowdown device for steam power plants includes a tube extending into a volume of water, the tube being formed with a multiplicity of holes having a substantially uniform diameter for introducing, into the water, steam that is flowing in the tube, the holes being disposed in rows spaced one from another a distance equal to at least 2.5 times the diameter of the holes.
