Abstract: An improved apparatus for recovering liquid aluminous metal from hot, aluminous skim comprising a combination of an open-one-end bowl to hold the hot skim and retain the residue after centrifuging, a bowl cover latchable to said bowl and with means to provide one or more controlled peripheral openings between said components which together form a skim centrifuge body, which centrifuge body is suspended and rotatable from a loosely fitting, mating linkage which has arcuate mating surfaces, the upper connecting part of which is connected to a source of rotation said rotational force source being provided with a non-rotating reaction and support surface which is preferably separated from the rotating load-carrying member by at least two, concentric bearings of replicate function and the apparatus preferably further consisting of a liquid collection means which surrounds horizontally the suspended centrifuge body during rotation.

Abstract: An aluminum-silicon brazing composition containing 0.05 to 0.3% lead by weight, with silicon in the range of 7 to 14% and magnesium in the range of 0.2 to 2%, preferably the composition being employed as a cladding layer on a magnesium-containing aluminum base core alloy.
