摘要:
A process for carrying out a chemical reaction on a liquid capable of exhibiting the Weissenberg effect, comprising rotating a body having a surface of rotation coaxial with the axis of rotation, the surface of rotation extending from a supply zone to a discharge zone, being an external surface at least in the region of its supply zone and having its discharge zone at a position of maximum radius, dipping the rotating supply zone into the liquid thereby to cause the liquid to flow up over the surface by the Weissenberg effect until it reaches the discharge zone there to be flung from the position of maximum radius by centrifugal forces, and effecting the chemical reaction as the liquid flows over the rotating surface between the supply zone and the discharge zone.

摘要:
A process for the production of heterogeneous articles such as heterofilaments and fibres containing a plurality of solid phases, comprises supplying a thermoplastic first material in particulate solid form to a surface of rotation of a rotating body so that it travels across said surface towards a discharge zone due to forces generated by the rotation of the body, melting the thermoplastic first material as it travels across the surface, supplying a second solid material to the surface, discharging both materials together from the discharge zone by centrifugal forces, and solidifying the thermoplastic material to form the heterogeneous article. The second material is preferably also thermoplastic and further solids, especially reinforcing fibres, can also be incorporated likewise.
