摘要:
The apparatus includes a sample tank for collecting and quieting a volume fraction of the fluid to be measured. The sample tank is in communication, at least at times, with a fluid containment via a filling line (L1) and a supply line (L2) connected, at least at times, with the filling line. The apparatus further includes a fluid measuring device having a vibration-type measurement pickup. A measuring tube of the measurement pickup is caused to vibrate during operation. The measuring tube is connected, at least at times, with the sample tank via a connecting line (L3), which is connected to an inlet end of the measurement pickup. The apparatus of the invention is especially suited for measuring liquids which are charged with gas and/or which tend to outgas.

The invention relates to a mounting for fixing a display unit or a computer mounting in the interior of a motor vehicle, said mounting having a telescopic rod, a suction element and a friction element. The mounting element is preferably braced in the interior of the motor vehicle by means of a gas spring, thus acting as a reversible mounting.

An aluminum alloy suitable for diecasting of components with high elongation in the cast state contains, as well as aluminum and unavoidable impurities, 8.0 to 11.5 w. % silicon, 0.3 to 0.8 w. % manganese, 0.08 to 0.4 w. % magnesium, max 0.4 w. % iron, max 0.1 w. % copper, max 0.1 w. % zinc, max 0.15 w. % titanium and 0.05 to 0.5 w. % molybdenum. Optionally, the alloy also contains 0.05 to 0.3 w. % zirconium, 30 to 300 ppm strontium or 5 to 30 ppm sodium and/or 1 to 30 ppm calcium for permanent refinement and for grain refinement gallium phosphide and/or indium phosphide in a quantity corresponding to 1 to 250 ppm phosphorus and/or titanium and boron added by way of an aluminum master alloy with 1 to 2 w. % Ti and 1 to 2 w. % B.
摘要:
The aim of the invention is to improve a mobile flue gas generator and to simplify a method for testing a flue gas indicator. The invention is characterised in that a mobile flue gas generator for simulating a real flue gas is proposed, whereby the mobile flue gas generator comprises an electric heating device for generating the flue gas.
摘要:
Inspecting gas detectors is difficult if the gas detectors are arranged in a place which is difficult to access. The provision of a test device which is in an operational connection with the gas detector or the heat detector facilitates the testing considerably.

An aluminium casting alloy contains: 2.0 to 3.5 w. % magnesium 0.15 to 0.35 w. % silicon 0.20 to 1.2 w. % manganese max. 0.40 w. % iron max. 0.10 w. % copper max. 0.05 w. % chromium max. 0.10 w. % zinc max. 0.003 w. % beryllium max. 0.20 w. % titanium max. 0.60 w. % cobalt max. 0.80 w. % cerium and aluminium as the remainder with further impurities individually max. 0.02 w. %, total max. 0.2 w. %. The aluminium alloy is particularly suitable for diecasting, thixocasting and thixoforging. A particular application is diecasting for components with high requirements for mechanical properties, as these are present even in the cast state and thus no further heat treatment is required.
