Example Output: 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).

Example Input: Pro dosažení pravidelné mikroporézní  struktury při koagulaci roztoků polyuretanů  nebo polyuretanmočovin se používá směsi roztoků  polymerů se zlepšenými koagulačními  vlastnostmi, která obsahuje roztok polyuretaninočoviny  a/nebo polyuretanu a dále roztok  modifikační přísady na bázi esteru a/nebo éteru  celulózy, která je obsažena v množství 1 až  50 % hmot., s výhodou 10 až 25 % hmot., na sušinu  polymerů a je omezeně snášenlivá nebo  zcela nesnášenlivá s polyuretanmočovinou  a/nebo polyuretanem, takže oba roztoky spolu  vytvářejí emulzi.
Example Output: To achieve regular microporous  structures in the coagulation of polyurethane solutions  or a polyurethane urea mixture of solutions is used  polymers with improved coagulation properties  properties that include polyurethane urea solution  and / or polyurethane and further a solution  ester and / or ether-based modifying additives  cellulose, which is present in an amount of 1 to 10% by weight  50% by weight, preferably 10 to 25% by weight, on dry weight basis  polymers and is poorly compatible or  completely intolerant with polyurethane  and / or polyurethane, so that the two solutions together  they form an emulsion.

Example Input: Vynález se týká zařízení pro ruční manipulaci s termoizolačním krytem (4) spa, zejména plavecké spa, mezi jeho krycí polohou a otevřenou polohou a naopak. Termoizolační kryt (4) obsahuje dvojici termoizolačních segmentů (41, 42) tvořenou unášecím termoizolačním segmentem (41) a unášeným termoizolačním segmentem (42), které jsou spolu otočně spojeny a v krycí poloze leží svými dolními stranami na obvodu spa. Unášecí termoizolační segment (41) je na spa otočně uložen a po obou stranách je spřažen s ovládacími prostředky. Ovládací prostředky obsahují akumulační člen (13), jehož pevná část (131) je uložena na spa a pohyblivá část (132) je spojena se soustavou pák. Na obou termoizolačních segmentech (41, 42) spa jsou vytvořena manipulační madla a na čelním konci unášeného segmentu (42) je uloženo pojezdové kolo (5).
Example Output:
BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for the manual handling of a thermo-insulating spa cover (4), in particular a swimming spa, between its covering position and an open position and vice versa. The thermo-insulating cover (4) comprises a pair of thermo-insulating segments (41, 42) formed by a entraining thermo-insulating segment (41) and a entrained thermo-insulating segment (42) which are pivotally connected to each other and lie in the covering position with their lower sides at the spa periphery. The entrainment thermo-insulating segment (41) is rotatably mounted on the spa and coupled to the control means on both sides. The actuating means comprises an accumulator member (13) whose fixed portion (131) is mounted on the spa and the movable portion (132) is connected to the lever assembly. Handling handles are formed on the two thermo-insulating spa segments (41, 42) and a travel wheel (5) is mounted on the front end of the driven segment (42).
