Translation of "Screwtop" in German

In a 250 ml screwtop bottle, 75.0 g of Bayferrox 3920 (from Bayer), 60 g of the 93% dissolved forms of the grinding resins in butyl acetate, suitable dispersing additives in a dosage of 7% active substance based on pigment and butyl acetate were initially charged in the amount required to attain 150.0 g, and homogenized by means of a laboratory spatula.

According to table 1, for a batch size of 100 g in each case, after initially charging the first position, the further positions are weighed individually into a 250 ml screwtop bottle while stirring.

In a 250 ml screwtop bottle, 30.0 g of Heliogen Blau L 7085 F (from BASF), 47.0 g of the 93% dissolved forms of the grinding resins in butyl acetate, suitable dispersing additives in a dosage of 20% active substance based on pigment and butyl acetate were initially charged in the amount required to attain 100.0 g, and homogenized by a laboratory spatula.

In a 250 ml screwtop bottle, 21.0 g of Spezialschwarz 6 specialty carbon black (from), 52.0 g of the 93% dissolved forms of the grinding resins in butyl acetate, suitable dispersing additives in a dosage of 40% active substance based on pigment and butyl acetate were initially charged in the amount required to attain 100.0 g, and homogenized by a laboratory spatula.

The solution of the hydrazone H obtained in the screwtop tube as described is subsequently analyzed for its hydrazone content by means of HPLC (High Pressure Liquid Chromatography) using the following operating conditions (the molar amount thereof results directly in the molar amount of glyoxal present in the liquid phase P):

To determine the content in a liquid phase P of glyoxal, 1 g (this amount can be increased correspondingly if required) of the derivatization solution D is weighed into a screwtop tube whose capacity is 10 ml.

Subsequently, a sample of the liquid phase P is weighed into the screwtop tube thus filled, the amount of which is in the range from 0.15to2.0g.

During this time, the corresponding hydrazone H of monomeric glyoxal forms from the monomeric glyoxal present in the screwtop tube by chemical reaction with 2,4-dinitrophenylhydrazine.

The screwtop opener in accordance with claim 5, wherein the second clamping jaw (41) on the second handle (15) has a metallic insert (67) in the handle (15) which is made of plastic.

The ends at the front of the legs of the other handle can be brought into contact with the screwtop.

This object is achieved with a screwtop opener having a first handle and a second handle which can be pivoted with respect to the first handle.

A screwtop can be grasped by the two clamping jaws, and a distance between the clamping jaws can be reduced by pivoting the two handles.

The length of the handle extending past or beyond the screwtop, and thus the rotating leverage, is always the same, regardless of the top size.

If the screwtop opener 11 is made of metal, the contact faces can be formed directly on the clamping jaws and not on the small plates, because such metallic inserts can then be omitted.

Now the straightedge 17 is placed on a screwtop and is again pushed back as far as possible into the first handle 13 .

The screwtop is thus clamped and can now be turned off the container by simultaneously pressing on the two handles 13, 15 .

This screwtop opener includes two elements, which can be displaced with respect to each other, a longer first handle arranged on a bottom having clamping jaws that project downward, and a shorter second handle arranged on a top having clamping jaws that project laterally beyond the sides of the first handle and downward from the first handle.
