Abstract: Aluminum alloy strips which are 30-150 m? thick, having a composition (in wt. %): Si<0.4; Fe: 1.5-1.9; Mn: 0.04-0.15; other elements: <0.05 each and 0.15 in total, remainder aluminum. The strips are used, in particular, for the manufacture of trays and dishes for the distribution of foodstuffs and fast food.

Abstract: The object of the invention is a method for manufacturing aluminum alloy strips with a thickness less than or equal to 12 &mgr;m, including:

Abstract: A method for manufacturing aluminum alloy strips with a thickness less than or equal to 12 &mgr;m, by obtaining an alloy with composition (weight %): Si:0.15-0.40; Fe: 1.10-1.70; Mg<0.02; Mn:0.30-0.50; other elements <0.05 each and total <0.15; remainder aluminum; continuously casting between rolls a strip of this alloy with a thickness between 2 and 10 mm; homogenizing this strip at a temperature between 450 and 620° C. with a duration between 8 and 40 hrs; cold-rolling of the homogenized strip; intermediate annealing of this cold-rolled strip to a temperature between 200 and 400° C., and with a duration between 8 and 15 hrs; cold-rolling of the annealed strip up to the final thickness less than or equal to 12 &mgr;m; and final annealing of the strip at a temperature between 200 and 300° C., with a duration of at least 50 hrs. The method is notably applied to the manufacturing of strips for aseptic food packages of the brick type.

Abstract: An installation and method for determining the level and density of a liquid in a tank. A reference probe leads into the tank, above the liquid. A single bubble probe is connected by a valve to the reference probe. The bubble probe extends into the tank and has a widened section disposed in the liquid. Compressed air is injected into the reference probe and the bubble probe. In an initial state, the valve is opened and there is no pressure difference between the reference probe and the bubble probe. The valve is then closed and the pressure difference between the reference probe and the bubble probe is measured. The level and density of the liquid is determined from measured values of the pressure difference.
