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.

A method for treating hot skim material to separate, recover, and prepare for use both aluminum and non-aluminous constituents contained in the hot skim materials involves a centrifuge having a rotatable bowl to receive a charge of skim material. The centrifuge then both consolidates the non-aluminous constituents thereof into a semi-porous cake and separates and discharges molten aluminum as the bowl is rotated. The semi-porous cake is cooled and found to be friable. Thereafter, the friable cake is crushed and screened to be used as a foaming and extending agent.

A suspended centrifuge apparatus has been improved by the addition of a restraint that closely maintains the original, static, vertical axis of a suspended centrifuge vessel during rotation. The restraint is preferably located to act on the lower half of the suspended vessel and preferably limits axial gyration to less than 5-degrees. A further improvement is a centrifuge bowl configuration which provides a protected surface to be acted on by a gyration restraint while partially eliminating centrifuge bowl capacity in a lower, central region subjected to inherently low centrifugal forces. An improved liquid separation process results from the use of the improved apparatus to better control the liquid discharge trajectory from the rotating centrifuge. Process control and safety are also improved.

Insulators, heated to a temperature which prevents solidification thereon, are used to confine all but one side of a continuous flow of initially-liquid metal alloy until it is solidified. The remaining side is confined by a thermally conductive material which is cooled by means to provide for essentially unidirectional rapid solidification of the alloy flow. Operational control and product quality are enhanced by establishing and conditioning a surface film on the liquid metal to be cast by controlling the gaseous environment available to the liquid metal prior to contact with the thermally conductive chill. The method and apparatus can produce cast strip with minimal shrinkage porosity from alloys with wide freezing ranges. The cast product is suitable for producing wrought products of high quality. The method is particularly applicable to aluminous alloys.

The handle device of the invention extends from a hand hold at one end of an elongated member to a cross member at the other end. The cross member is connected to straps for ready attachment to and detachment from a child's vehicle. A pair of interengageable surfaces, such as Velcro. RTM. material, are positioned on each strap to enable the free end of the strap to be secured after being looped around a structural part of a child's vehicle. One engageable surface of the pair is fixed to the cross member, and the second engageable surface of the pair is on the free end of the strap. A pair of additional engageable surfaces for anchoring the free ends of the straps is positioned on the cross member between the parts of the straps fixed to the cross member. A duplicate of the cross member may be used for the hand hold and other purposes as well, such as connecting two vehicles together.

A process for making a workpiece suitable for being hot worked to produce a wrought metal poduct is described. Aluminum alloy powder is cold compacted and then heated in an inert environment to provide a sinter-sealed shape. The resultant workpiece may then be subjected to conventional processing to produce the desired wrought product.
