摘要： A delivery device for delivering articles to be heated within a compound furnace, including at least two furnace chambers differing in heating conditions and which can effectively prevent damage to the articles by melt adhesion due to contact with each other and which can also reduce the adverse influence of high temperatures upon the component members of the delivery device is disclosed as including clamps which are capable of reciprocating within a delivery passage and which have the function of clamping and unclamping the articles to be heated so as to deliver or transport the same. Running rods, upon which the clamps are fixed, are adapted to move along the delivery passage and a main drive source for driving the rods and clamps, as well as a subsidiary drive source for performing the clamping and unclamping operations of the clamps are also provided. A movement converting transmission mechanism for converting the linear driving force of the subsidiary drive source into a rotary drive force for rotating the running rods in order to actuate the clamps for performance of the clamping and unclamping operations is included and a clamp positioning mechanism for determining the stopping position of the clamps is operatively associated with the running rods. The movement converting transmission mechanism may include a rack-and-pinion mechanism, a slide bar or rod-crank mechanism, an actuator-gear mechanism, or a cylindrical cam mechanism.

摘要： A process for converting aluminum scrap into finished articles by compaction, heating and extrusion. The process comprises the steps of compacting the aluminum scrap at ambient temperature into a billet having a density between 1.8 and 2.4 g/cm.sup.3, heating the compacted billet to a temperature between 350.degree. and 550.degree. C, compacting the heated billet into a dense mass having a density about 2.4 g/cm.sup.3 either in an extrusion container, while maintaining conditions under which the air pressure at the outer periphery of the billet is lower than that in the central portion of the billet, or externally of the extrusion container, and subsequently, after completion of the second compaction, consolidating the secondly compacted billet by extrusion through an extrusion die fitted to the container while maintaining the above mentioned conditions, whereby void-free and scab-free finished articles of good quality are efficiently produced with a small apparatus using little energy.
