A device and a method for the thermal reshaping of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the reshaping, the hose blank is arranged in a shell-like, single- or multi-piece molding tool with a hollow body, wherein the tempering of the molding tool that is necessary for reshaping occurs by means of clamp-like tempering elements which are shaped congruently to the outer surface of the mold and which close form-fittingly over the mold, while the molding tool itself does not comprise any tempering system at all, in particular no ducts or other hollow spaces for circulating a tempering medium, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a correspondingly constant temperature is positioned against the molding tool.

A method of making a wire with multiple coating layers can comprise: preheating a wire to a temperature T.sub.preheat to form a pre-heated wire; using a first extruder to coat the pre-heated wire with the first coating material to form a first coated wire; passing the first coated wire to a second extruder without storing the first coated wire, coating the first coated wire with a second coating material to form a second coated wire; and cooling the second coated wire.

The invention is directed to melt-processable carbon fiber precursors which have the capability of thermal stabilization in air followed by carbonization in inert atmosphere which make them cost effective and widen their applications.

Aspects of the disclosure relate to methods and systems for producing a preferably strand-like extrudate.

A method of forming a fiber-reinforced molding compound. The method includes establishing a melt stream of a source material including a first polymeric material having a first melt temperature in an extruder and dosing a composite material into the melt stream. The composite material includes pre-impregnated reinforcing fibers comprising reinforcing filaments and a second polymeric material having a second melt temperature greater than the first melt temperature. The composite material has at least 30% of the reinforcing filaments protected by the polymeric material such that the polymeric material surrounds each filament completely forming a barrier between it and an adjacent filament in the at least 30% of the filaments. The temperature of the melt stream at dosing is below the second melt temperature. The method includes forming a molding compound from the source and composite materials. The method includes dispensing the molding compound to produce a part.

Assay cartridges are described that have a detection chamber, preferably having integrated electrodes, and other fluidic components which may include sample chambers, waste chambers, conduits, vents, bubble traps, reagent chambers, dry reagent pill zones and the like. In certain embodiments, these cartridges are adapted to receive and analyze a sample collected on an applicator stick. Also described are kits including such cartridges and a cartridge reader configured to analyze an assay conducted using an assay cartridge.

An extruding process and assembly for creating a structural form, which includes the steps of bundling and conveying at least one length of a material into an extruder, reshaping a cross section of the bundle in a first stage of the extruder, extruding a material using any combination of heat and pressure around and between the lengths of material, and outputting a finished article having a cross sectional profile in which the materials are structurally supported by the extruded and hardened material. Other steps include an intermediate chilling stage between reshaping and extruding, and for preventing the extruded material from back flowing. The extruded material further includes any of a polymeric or structural foam material and can exhibit any of a rounded, square, rectangular or I beam cross sectional profile.
