Monthly professional magazine in the field of engineering Strojarstvo/Strojirenstvi with more than 15 years of tradition, is published in the Czech and in the Slovak Republic, in print and electronic version. With the new year 2012 we prepared for our readers benefit from subscription to the print and electronic edition of the magazine.

In this contribution is described a structural design and a solution of system attachment of supporting wheels for the given rotational platform in airplane parking in hall. In the contribution is also presented a structural modification of peripheral beams in the already realized airplane platforms with regard to their deformation.

The current T-model in the E-Class from Mercedes has an especially large fuel filler flap, since it is intended to accommodate variable fueling options. This flap has recently been converted to the new Ultramid TOP 4000 from BASF, a mineral-filled semi-aromatic polyamide (PA 6/6T). The conductive engineering resin is an improved version of the Ultramid TOP 3000 introduced in 2007 and offers primarily greater stiffness and dimensional stability. Just like its predecessor, the new material is also suitable for online painting. This means: plastic components made from Ultramid TOP 4000 can, without additional effort or costs, withstand the various baths and painting operations to which the rest of the body is subjected. This material thus represents one more step towards the lightweight plastic automobile body thus enabling further reduction of fuel consumption and emissions.

The chemical nickeling is not a very often-used method of surface treatment with regard to its industrial applications. This fact is given due to a higher consumption of energy (the working temperatures are between 86 and 92°C) as well as there are demanding requirements concerning purity and precision during the nickeling process.
