    摘要： Apparatus for the continuous extrusion of metals in which feed is introduced into a pair of circumferential grooves in a rotating wheel to contact arcuate tooling and abutments. The feed is constrained by the abutments to flow through exit apertures in a die top from the respective grooves to a substantially toroidal chamber around a hollow, open ended, portal mandrel to extrude through an annular die orifice as a cladding for a continuous core. Cooling air may be supplied to the interior of the cladding, which is subsequently swaged down on to the core. A solid mandrel may be utilized where it is desired to extrude tube.

    摘要： A method of fabricating composite metal wires such as aluminium clad steel wires is disclosed which comprises providing a core of hard metal with a cladding of soft metal by extrusion. In fabricating a composite metal wire by extrusion, a core is generally aligned, polished, cleaned or otherwise pretreated before entering an extruder so that a high and variable tension is imparted to the core. By avoiding such tension variation and maintaining the core under a constant low tension and by electrically heating the core before the core enters the extruder, a composite metal wire of improved quality is fabricated in a stable manner.

    摘要： A process allows the production of composite sections made of at least two component parts such as conductor rails or the like having a beam-like section with a facing in the form of a conductive metal strip. The process makes use of an extrusion die whereby at least one of the components of the composite section is fed to the die by means of frictional force on a face which moves continuously towards the die.

    摘要： AN EXTRUSION PROCESS FOR FORMING CONSUMABLE ANODES AND THE PRODUCT PRODUCED THEREIN. THE PROCESS COMPRISES THE CO-EXTRUSION OF A WIRE CORE HAVING A NON-FERROUS LIGHT METAL SURFACE WITH AN OVERCOATING OF A DISSIMILAR LIGHT METAL. A SYNTHETICALLY PRODUCED NON-FERROUS METAL OXIDE LAYER IS INTERPOSED BETWEEN THE DISSIMILAR LIGHT METAL SURFACES TO REDUCE THE INCIDENCE OF CORE WIRE BREAKAGE DURING EXTRUSION OPERATIONS. IT IS BELIEVED THAT ALLOYING OF THE LIGHT METAL CORE SURFACE WITH THE DISIMILAR EXTRUDED OVERCOATING IS INIBITED BY OXIDE LAYER, THEREBY SUBSTANTIALLY ELIMINATING ADHERENCE OF A LOW MELTING, NON-FERROUS ALLOY TO THE EXTRUSION DIE. BREAKAGE OF THE CORE WIRE DURING EXTRUSION IS THEREBY MINUMIZED.

    摘要： The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted.The method envisioned produces projectile bodies from rod or wire stock by encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.
