    摘要： The present invention relates to a colour filter means having optical activity under the influence of a polarized light for mounting frontwards of a natural or artificial imaging device (8). The colour filter means contains first optically active material (1) and first polarizer (2), both having optical axis aligned in the same direction and plane perpendicular to the optical axis. The colour filter means also contains a colour filter (5) dyed in its material. The first optically active material (1) can be optionally rotated around its optical axis and being in front of the imaging device (8). The core feature of the colour filter means is that from the aspect of sensing an unpolarized light passing therethrough keeps its colour or shows up a monochrome effect while the colour of a plane-polarized light is modified thereby in a pre-defined manner.

    摘要： Process for increasing the water discharge of water delivering drilled wells, which can be characterized in that into the filter section of the well weak acids with a dissociation constant being less than K.sub.d =10.sup.-3 are introduced. After a dwelling period of longer duration, expediently 10 to 48 hours, as well as compressing, flushing is performed by means of a scavenging pump. Thereafter the solution of sodium bicarbonate and/or sodium hypochlorite is introduced into the filter section. After a longer dwelling period, expediently one to thirty-six hours, flushing is performed by means of the scavenging pump. As weak acids with a dissociation constant being less than K.sub.d =10.sup.-3 acetic acid, tartaric acid, citric acid, metaboric and/or tetraboric acid is used.
