Účelem vynálezu byl výhodnější způsob  přípravy metalokomplexního barviva  azokopulací 6-nitro-l-diazo-2-naftol-4-  -sulfonové kyseliny 2-naftolem a následnou  chromací reakčního produktu.  Účelu bylo dosaženo prováděním azokopulace  za přítomnosti dvojmocného kationtu  zinku nebo trojmocného kationtu kobaltu  ve formě amokomplexu v množství 1.10-2  až 1.10“1 mol na 1 mol diazotační komponenty.
The purpose of the invention was a more advantageous method  preparation of metal complex dye  azocopulation of 6-nitro-1-diazo-2-naphthol-4-  -sulfonic acid 2-naphthol and subsequent  by chromating the reaction product.  The purpose was achieved by carrying out azocopulation  in the presence of a divalent cation  zinc or trivalent cobalt cation  in the form of an amocomplex in an amount of 1.10-2  up to 1.10 "1 mole per mole of diazotation component.

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).

Vzduchová stříkací pistole ,pro stříkání  nátěrových hmot s regulací šíře střiku, má  kuželku z plastické hmoty nalisovanou na  tyčce, těsnicí otvor a tyčka je našroubována  ve šroubu regulace, který je zašroubován v  pouzdru, umístěném v těle pistole. Tyčka je  těsněna ucpávkou regulace z plastické hmoty,  nalisovanou v pouzdru, z něhož vyčnívá  válcová část šroubu se závitovou částí tyčky.  Řeší provedení vzduchové stříkací pistole  pro stříkání nátěrových hmot i jiných kapalin  s regulací šíře střiku. Její provedení  umožňuje pohotovou regulaci šíře střiku s  vizuální kontrolou a zabezpečenou reprodukovatelností  nastavení šíře střiku.

Air spray gun, for spraying  paints with spray width control, has  plastic cone pressed on  the rod, the sealing hole and the rod are screwed  in the control screw that is screwed in  a holster placed in the gun body. The stick is  sealed with plastic packing,  pressed in the case from which it protrudes  the cylindrical part of the screw with the threaded portion of the rod.  It solves the design of an air spray gun  for spraying paints and other liquids  with spray width control. Its execution  allows quick control of spray width s  visual inspection and secure reproducibility  adjusting the spray width.
