Abstract:
A cellulose fibre-based support of which at least one surface is coated with a layer containing at least one water-soluble polymer having hydroxyl functions, at least some of which have been reacted beforehand with at least one organic molecule that contains at least one vinylic function, characterized in that said organic molecule also has an aldehyde function. Method for production thereof.
Abstract:
A spout (10) is removably mounted to a hopper (1) of an electrolytic cell by a coupling (28) allowing the spout (10) to rock relative to the spout when jarred. A handler (40) is provided for the mounting of the spout (10) onto the hopper (1) without an operator entering into the electrolytic cell.
