Abstract: A packaging blank is scored with several substantially parallel laterally spaced apart score lines adjacent the intended location of a rounded edge on the container produced from the blank. The score lines are formed on the inside surface of the blank which places the score lines inside the container formed from the blank. When the blank is bent into shape at the rounded edges, a portion of the total deflection is absorbed by each score line whereby the resulting container edge is a gradual curve rather than a single sharp crease. Placing the score lines on the inside of the formed container results in opposing faces of the container being planar and parallel to one another.

Abstract: The invention relates to an ATR spectrometer, containing an optical probe having a sensor made of transparent material and a feed line and an exit line for light, wherein the sensor contains an optical polymer or a mixture of different optical polymers. The probe of the spectrometer according to the invention essentially has the advantages that it is inexpensive and extremely flexible, and that it can be matched to the concentration range of the solution to be examined, which makes it possible to fill the gaps in terms of measurable concentrations between conventional transmission spectroscopy and prior ATR spectroscopy.

Abstract: A catalyst formed by the reaction of a magnesium alkoxide dispersion having a particle size of from 100 to 3000 nm with a compound of a metal selected from the group comprising titanium, zirconium, vanadium and chromium and then with a chlorine-containing organoaluminum compound possesses a very good hydrogen responsiveness and a high activity even in the presence of molecular-weight regulators such as hydrogen. The catalyst is therefore outstandingly suitable for the production of low molecular-weight polyolefins. The catalyst makes possible the production of waxes having a reduced residual ash content. The large particle diameter and the low fines content of the polymer powder produced by suspension polymerization with this catalyst enables easy removal of the suspension medium and drying. The catalyst is furthermore advantageously used in solution polymerization and, because of the large particle diameter, in gas phase polymerization for producing low molecular-weight poly-1-olefins.
