Patent DE-3918285-A1 (DE)
Title: Process and apparatus for washing (cleaning) mixing apparatuses for multi-component plastics, in particular polyurethane
Inventor: LERCH BURGHARD
IPC: B01F15/00
Filed: 1989-06-05
Abstract: The process according to the invention operates in particular in connection with low-pressure agitator-equipped mixing apparatuses which are not mechanically cleaned but cleaned by a washing agent. The washing agent used is water containing a surface-active agent instead of methylene chloride or a similar solvent which can be hazardous to health. The washing agent, after it leaves the mixing chamber of the low-pressure mixing apparatus, i.e. when it is contaminated, is fed to a filter and purified to the extent that it can be recycled to the washing agent circulation. Preferably, the contaminated washing water, before being filtered in a filter 17, is fed to a sedimentation vessel 8 in which a sludge 11 accumulates at the bottom and floating froth residues 10 collect at the top. These constituents can be immediately disposed of. The already relatively clear washing water is then filtered and recycled to the washing water circulation. As a result, the volume to be disposed of (sludge 11, floating froth residues 10 and exchanged filter elements) is very small in relation to the total volume of the washing water, so that the process has advantages not only from the health aspect but can also be carried out economically (Fig.). <IMAGE>

Title: Prodn. of optically limiting plates - by giving acrylic] sheet suitable surface texture, coating it with light-sensitive material and illuminating it so that parts are blackened
Inventor: NAWRATH PETER
IPC: G02B3/08
Filed: 1990-07-11
Abstract: Optically limiting plates or Fresnel lenses which are free of light scattering are pref. made of acrylic polymer by blackening prism areas which are not required to be seen through, or, as the case may be, not required for refraction. The whole area of the prisms is coated with a light-sensitive material; it is then irradiated in such a way that the sides of the prisms not needed for refraction are illuminated either weakly or not at all, so that, after being developed photographically, the light transmission is controlled. - An acrylic sheet (1) is given a surface texture. To produce an optically limiting system this surface is treated with a suitable photochemical prepn. and the sheet (1) is exposed to light (20) in the form of a known density of bundles of light rays (or laser beam). By this means the irradiated areas are blackened, whilst the remainder receive no light and they remain transparent. The method of illumination can be varied; the use of parallel bundles of light has variations.
