Abstract: A method for producing an aluminum alloy foam wherein an aluminum alloy, in molten form, infiltrates the interstices of a preform of silicon elastomer elements, by means of a conventional molding process, typically a low-pressure process, followed by the elimination of the preform broken down into silica powder during the molding cycle and/or an additional baking cycle.

Abstract: The invention concerns a method for producing an aluminium alloy foam, consisting essentially of the aluminium alloy, in molten form, infiltrating the interstices of a preform consisting of silicon elastomer elements, by means of a conventional moulding process, typically a low-pressure process, followed by the elimination of the preform broken down into silica powder during the moulding cycle and/or an additional baking cycle.

Abstract: A cursor (151), designated to slide in a case formed by two thicknesses lying alongside the cursor, is formed by cuts parallel to the direction of sliding and by weak links designed to be broken by action on the cursor (151) in the direction of f1 which causes its initial sliding; cuts parallel to the direction of sliding form elongate slots (153) running alongside the cursor (151) and each terminating in a stop (151X) formed by the cursor and in a stop (121x) formed by the material of the intermediate thickness (121) from which the cursor is formed; the two stops (121X; 151X) interact to limit the sliding of the cursor with respect to the case.
