Abstract: Apparatus and process for automating a vacuum degasification cycle for metal alloys, particularly aluminum alloys. The process comprises adjusting the degasification speed to sequentially correspond to a plurality of sets of degasification speed parameters. Each set of degasification speed parameters corresponds to a predetermined desired degasification speed. The degasification speed may be adjusted by adjusting the vacuum surrounding the alloy. The degasification speed is triggered to change from corresponding to one set of parameters to another set of parameters by the sensing of a series of predetermined partial pressures of gas in the alloy. The apparatus includes an inlet-outlet assembly for transforming given indications into a numerical form for the parameters of the degasification cycle and a calculator assembly adapted to transform the speed of degasification into variations of theoretical partial pressure and to regulate the pressure in the enclosure of the furnace to obtain an identical variation to that required based upon the indications of the standard curve placed in the assembly memories. Several furnaces may be regulated. The temperature of the metal may be regulated at a level equivalent to that required before casting. The apparatus can include a microprocessor.

Abstract: Die Erfindung betrifft ein Verfahren zur Verringerung des Säuregehaltes einer salpetersauren Lösung unter Verwendung eines Elektrolysestromes, der in der Lage ist, HNO3 an der Kathode zu reduzieren und eine Vorrichtung zur Durchführung dieses Verfahrens. Bei den bekannten, elektrochemischen Salpetersäurereduktionsverfahren entstehen Stickstoffverbindungen, wie zum Beispiel höhere Stickoxide oder Ammoniak bzw. Ammoniumionen, die meist in weiteren Verfahrensschritten beseitigt werden müssen. Aufgabe der Erfindung ist es daher, ein Verfahren zu schaffen, mit welchem eine Verringerung des Säuregehaltes einer salpetersauren Lösung in einem kontinuierlichen Prozeß unter Bildung ungiftiger, gasförmiger Zersetzungsprodukte der HNO3 durchgeführt werden kann. Die Erfindung erreicht dies dadurch, daß die salpetersaure Lösung in zwei Volumenanteile aufgeteilt wird, der eine Teil elektrolytisch zu Ammoniumnitrat, der andere Volumenanteil elektrolytisch zu nitrosen Gasen reduziert wird und daß die Reaktionsprodukte aus beiden Volumenanteilen zusammengeführt und bei einer Temperatur im Bereich von 50°C bis unterhalb des Siedepunktes der die Reaktionsprodukte enthaltenden bzw. aufnehmenden Lösung durch Erwärmen der Lösung reagieren gelassen werden. Die Volumenanteile der salpetersauren Lösung können sowohl in 2 verschiedenen Elektrolysezellen als auch in einer einzigen Zelle mit 2 verschieden ausgebildeten Kathoden behandelt werden. Als Denitrierungsprodukte bilden sich die ungiftigen Gase N2 und N2O. Wird in einer einzigen Elektrolysezelle reduziert, so kann die eine Kathode aus einem Graphitstab, die andere Kathode aus einem Graphitkörner-Schüttbett, die Anode als Platin oder platiniertem Tantal und das zwischen den Kathoden und der Anode befindlichen Diaphragma aus einem Glasfritten- oder aus einem porösen Keramikkörper bestehen.

Abstract: For determining a path of movement of a tool along shoe bottom marginal portions a series of points along such path is selected and information regarding such points stored in the form of digitised co-ordinate axis values by computer, from which information the path can subsequently be derived. The selected points are spaced by a predetermined distance (which may be the same for each pair of adjacent points) regardless of shoe bottom contour. To this end, when each point is digitised, the tool and shoe bottom are relatively moved apart by the predetermined distance along one e.g. a heightwise dimension (preferably an axis). Thereafter in returning the tool and shoe bottom into engagement along said one dimension and/or along a second, e.g. widthwise, dimension, movement also takes place automatically along a third, e.g. lengthwise, dimension thus to maintain the predetermined distance. Computer also has interpolation, grading (for size) and reversing (left/right) programmes.

Abstract: The assembly (10) protects a track chain (28) from damage when some foreign object, such as a rock, is trapped between the chain link assembly (28) and a chain supporting element (24). An idler link (30) is pivotally connected to a track frame (12) and a recoilable rear idler (24) is rotatably positioned on an idler hub (54) itself pivotally connected to the idler link (30). An increase in tension on the endless chain link assembly (28) causes the idler hub (54) to rotate away from the endless chain link assembly (28) decreasing track path length and, consequently, tension. This rotation is resiliently resisted by a recoil pad (66) mounted between the idler hub (54) and the idler link (30). An adjustable tensile link (68) prevents any recoil up to a preselected endless chain link assembly (28) tension.
