摘要： When forming ultra-conductive wire, multi-walled carbon nanotubes (MWCNTs) are dispersed and de-agglomerated in hot metal. The MWCNTs are dispersed in a precursor matrix via mixing and sintering to form precursor material, which is hot-extruded multiple rounds at a predetermined temperature to form a nano-composite material. The nano-composite material is inserted into a metal bar to form a nano-composite billet (306), which is subjected to multiple rounds of hot extrusion to form an ultra-conductive material. The ultra-conductive material is subjected to one or more rounds of hot wire drawing to form an ultra-conductive wire comprising a nano-composite filament.

摘要： The present invention relates to improvements of equal channel angular extrusion (ECAE). It provides a preservation of billet shape, a simple billet ejection from tool, application of backpressure and minimizes or eliminates flashes and cracks during multi-pass processing. That way, ECAE can be performed at a large scale as a productive and cost effective industrial operation without billet reshaping and preheating between passes.

摘要： An apparatus for extruding a powdered material forms an elongated pellet. The extrusion apparatus includes a connection mechanism arranged between the inlet and the constriction passages for continuously connecting two successively charged portions of the powdered material when the powdered material is repeatedly charged. By this mechanism, the formerly charged and semicompacted portion of the powdered material and the border surface upon the subsequent portion are broken, either by a core piece or a modified die cavity, whereby the portions of the powdered material are merged with each other before the constriction.

摘要： Disclosed is a method and an apparatus for extruding a powder material to form a pellet. The method includes the steps of: preparing a semicompacted powdered material for temporary placement in a die cavity with a constricting passage for receiving a charge of the powdered material; charging the die cavity containing the semicompacted powdered material with a predetermined amount of the powdered material; and pressing the charged powder material into the die cavity against the semicompacted material and extruding the semicompacted material from the die cavity through the constricting passage, whereby the semicompacted material is completely compressed to form a pellet, and the charged powdered material is incompletely compressed into a semicompacted form. The charging and pressing steps are repeated to successively form the powdered material into pellets via the semicompacted material.In the apparatus, a longitudinal die cavity passes through a die, and includes a first passage and a constricting passage subsequently connecting to the first passage, in which the lateral sectional dimension of the first passage is substantially uniform and the lateral sectional dimension of the constricting passage is gradually reduced. A punch is movable relative to the die in the longitudinal direction of the die cavity for slidable insertion into the die cavity, and regulated so that, when the punch is inserted into the die cavity, the punch does not substantially reach the constricting passage.

摘要： The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.

摘要： A method for the multi-stage compression of a mass in a press, especially an extrusion press containing plastic or elastic masses. The mass to be extruded is precompressed up to a preliminary pressure by the rapid advance of the pressure piston. The initial advance takes place at a high rate without the occurrence of impermissibly high temperatures of the mass or the enclosed gas. The subsequent compression to higher pressure levels takes place in a sequence of stages in each of which the rate of advance of the pressure piston is constant. The rate of advance is increased from stage to stage until a final extrusion pressure is reached. An apparatus for carrying out the method of the invention includes a hydraulic flow rate regulator which is controlled on the basis of signals that are related to the pressure measured in the hydraulic system. The pressure signals may be derived by potentiometers energized by pressure-dependent switches.

摘要： Powdered metal is continuously introduced into a die cavity in discrete quantities and compacted into bar segments to form a bar. The cavity has a fixed cross-sectional area and is open at both ends, except during the initial compaction when one end is closed. After formation of a length of the bar, the frictional resistance between the bar and the cavity wall is relied on so that the bar remaining in the cavity serves as a stopper for subsequent compactions of the discrete quantities of powdered metal to form the continuous bar. The bar is forced out of the cavity and may be passed through an induction furnace for sintering, and through a swager, all preferably in a continuous operation. Also provided is means for varying the compaction so that the bar lengths formed from the discrete quantities of powdered metal are compacted and bonded into a bar of substantially uniform physical characteristics along its length.

摘要： In the manufacture of fodder briquettes, especially for ruminants, the green crops are artificially dried to a moisture content of 15-22% and, while at a temperature of 45*-65* C. (110*-150* F.), are fed to a reciprocating briquette press for being compressed to a specific weight of 0.7-0.9 grams per cm.3. The briquette rod produced is cooled while passing through a guide pipe somewhat larger in diameter than the rod which is displaced through the guide pipe against a resistance to counteract longitudinal expansion of the briquette rod.

摘要： A food-extruding machine has a ram coupled to a piston that compresses moldable food product held in a container through aligned openings of a removable extrusion plate and a severing plate. When the severing plate is moved to shift the extrusion plate and severing plate openings out of alignment then the food product extrusions are chopped into chunks. The extrusion and severing cycle is repeated until the ram-driven piston has exhausted all the food product from the container. The extrusion lengths may be varied by an adjustable control. The extrusion plate and a retaining recess for holding the extrusion plate have matched locating edges so that the extrusion plate openings and severing plate openings can be quickly and accurately aligned.
