answer:
In the present invention there is disclosed a pack (1) for containing pourable goods such as liquids and small free-flowing granules, said pack comprising an inner, polygonal blown plastic container (2)  accommodating the goods to be packaged, and a sleeve-like cardboard jacket (3), which surrounds the blown plastic container (2) and is positively fixed thereto, for which purpose the blown plastic container (2) is formed in one corner with at least one indentation (6, 7) in its outer edge to which corresponds a polygonal part (8, 9) of the cardboard jacket (3), which is designed to fold inwards during assembly for locking purposes and which is arranged symmetrically to a corner fold line (10) of the jacket (3), being connected to the jacket (3) via at least one die-cut line (11e, 11d) extending substantially transversely of the corner fold line and at least two fold lines (11a, 11b) arranged in the shape of a V to one another, wherein the improvement is characterized in that: the polygonal part (8, 9) of the jacket (3) in the unfolded state is made quadrangular, the V-shaped fold lines (11a, 11b) have free ends individually connected to one end of two straight die-cut lines(11e, 11d), respectively, the other ends of said two die-cut lines (11e, 11d) are joined together at a median point above the V-shaped fold lines (11a, 11b), and that the corner-shaped indentation (6, 7) of said container (2) is bordered by flat surfaces (6a) for snugly receiving said polygonal part (8, 9) of said jacket (3).


question:
Donepezilhydrochlorid, 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidinhydrochlorid, je vpredkládaném vynálezu poskytován ve forme modifikace, která je pri farmaceutickém pouzití odolná proti zahrívání a proti vlhkosti. Lze ji prumyslove vyrábet. Modifikace je specifikována píky v práskovém rentgenovém difraktogramu a absorpcními píky vinfracerveném absorpcním spektru v bromidu draselném.
answer:
Donepezil hydrochloride, 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidine hydrochloride, is provided in the presented invention in the form of a modification, which is stable against heat and humidity in the pharmaceutical use. It can be industrially produced. The modification is specified by peaks in X-ray powder diffraction pattern and absorption peaks in infrared absorption spectra in potassium bromide.


question:
Směrový reflektor s odraznou plochou za  zdrojem světla, který má před zdrojem /1 /  představené zrcadlo /2/ se zakřivenou optickou  plochou /21/, vypuklou směrem ke zdroji  /1/ světla. Svislý řez optickou plochou /21/  procházející optickou osou je tvořen křivkou,  jejíž poloměr křivosti se zvětšuje směrem k  dolní části výstupní plochy /3/ reflektoru a  zároveň se její vzdálenost od výstupní plochy  /3/ zvětšuje.
answer:

Directional reflector with reflective surface behind  a light source that has a source before / 1 /  presented mirror (2) with curved optical  surface (21), extending towards the source  / 1 / lights. Optical section of optical surface / 21 /  passing through the optical axis is a curve  whose radius of curvature increases towards  the lower portion of the exit surface (3) of the reflector a  at the same time its distance from the exit area  / 3 / increases.
