A method of producing an ion-exchange membrane suitable for use in an electrolytic cell in which the membrane is expanded by stretching at elevated temperature to increase the surface area per unit weight of the membrane. The membrane may be annealed at elevated temperature, and may be cooled while restrained in the expanded state. The membrane when used in an electrolytic cell remains taut and unwrinkled and leads to reduced voltage operation of the cell.

Production of stretched ion-exchange membrane

A method of joining together a sheet or sheets of an organic polymer which is not normally melt-processable, e.g. polytetrafluoroethylene, the method comprising the steps of

Production of sheet materials

A device for supporting a sheet diaphragm on to a surface of a cathode which is made of a flexible insulating material and which can be caused or allowed to expand into the space between the anode and the diaphragm so that the diaphragm is pressed into contact with the cathode.

Diaphragm cells

Apparatus for spraying a predetermined amount of paint, especially electroconductive paint as used for coating metal anodes, which comprises in combination an electrostatic spray gun and a paint delivery device for the gun which operates on a single displacement diaphragm principle.
