Abstract: The invention relates to a film comprising an interpenetrating network, its uses and processes for making the same. The film produced displays good durability, chemical resistance and transparency. The film is produced from an interpenetrating network formed as a colloidal suspension in an organic solvent and a particulate solid.

Abstract: A partially cured reinforced polymeric article is provided which includes one or more layers. Each layer may include a reinforcing web, a partially cured cross-linkable polymeric composition being formed from, an ultra-violet (UV) curable polymeric resin; and a photoinitiator, and/or a photoinitiator and a thermal initiator. The polymeric resin and photoinitiator may be configured to permit formation of the partially cured cross-linkable polymeric composition in less than approximately 120 seconds.

Abstract: To prevent the formation of internal short circuits between electrodes of a rechargeable electrochemical cell, the electrolyte is maintained in continuous motion at least during charging when, in the case of an air-depolarized cell with a positive oxygen electrode and a negative zinc electrode, an air stream is introduced into a cylindrical cell casing through a multiplicity of orifices in a generally tangential direction and at increasing distances from the housing axis to impart rotation about that axis to the liquid; upon the subsequent discharge, a valve redirects the air stream into a compartment separated from the electrolyte by the oxygen electrode.
