    Abstract: An extrusion die for the extrusion of continuous hollow sections of plastic materials reinforced with fibers or molecules. Both the outer nozzle and inner mandrel are rotatable and have channels within them to allow the extrudate to flow through either the body of the nozzle or of the mandrel into the space between them to impart a radial component to the fibers. Likewise, a helical channel formed in either the nozzle or mandrel imparts a tangential component to the fibers. The flow may also be straight through the die which gives the fibers an axial component.

    Abstract: A method of materials processing (e.g. polymer extrusion) in which the material flows along an axially extending passageway. A pressure differential is established across the passageway transverse to the axial flow direction so as to create a flow of material through the die which has a velocity component transverse to the axial flow direction. Preferably the pressure differential transverse to the extrusion direction is continuous thereby estabilshing a continuous change of velocity component transverse to the axial flow direction. Preferably also there is at least one reversal of transverse pressure differential (and hence transverse velocity component). Apparatus for performing this method comprises for example, successive sections (3-5) of identical trapezoidal cross section with adjacent ones of these sections having their cross-sections displaced through 180.degree. relative to each other.

    Abstract: In an apparatus or installation having a metal part corroding in an electrolyte contacting the part, that part is a first electrode electrically insulated from a second electrode, for example another part of the apparatus, also contacting the electrolyte. No external electrical power is applied to the electrodes/electrolyte system. The low frequency voltage between the electrodes is observed. This voltage is a low frequency noise signal. Amplitude values of the signal are measured and subjected to an averaging computation yielding data indicating the corrosion rate of the first electrode and the nature of the corrosion.
