Abstract: Apparatus for transferring liquid metals from a collection container (9) to a receiving container (1), comprising: a receiving container in the form of a ladle (1) provided with a mouth (4) for the introduction of the metal, means (8) for transferring the liquid metal from a collection container (9) to the ladle (1), the means comprising a cover (7) which can engage the mouth (4) of the ladle (1) in a leak-tight manner and which has a first opening (14) with which a liquid-transfer duct (11) is associated and at least one second opening (16) with which means (17, 18) for generating a reduced pressure are associated, and handling means (20) arranged for moving the transfer means (8) between a position in which the cover (7) engages the mouth (4) of the ladle (1) and the transfer duct (11) is immersed in the collection container (9) and a position of disengagement from the mouth (4) of the ladle (1).

Abstract: Apparatus for casting molten metal for the production of metal castings by “lost-foam” technology, comprises: a first container (15) of molten metal, a second container (1) having an upper mouth and containing a bath of granular material (2), immersed in which is a pattern (3, 3a) made of expanded material which can evaporate when contacted by the molten metal, and filling means (14) for supplying the molten metal from the first container (15) to the pattern (3, 3a) in the second container (1), and means for applying a partial vacuum to the second container (1), the means comprising a removable cover (7) which can seal the mouth of the second container (1) in a leaktight manner and which has a first opening (9) with which vacuum-generating means (10, 11) are associated and a second opening (13) with which the filling means (14) are associated in a leaktight manner so that, when the cover (7) is fitted on the second container (1) in a leaktight manner and the vacuum-generating means (10, 11) are ac
