An induction heater has a conductor loop (1) in which a large alternating current is induced by a toroidal primary transformer (8). An annular secondary magnetic core (4) encircles a straight length of the conductor loop (1) and is itself enclosed by inner and outer cylinders (2 and 5) interconnected by annular end plates (6 and 9). The current in the conductor (1) produces magnetic flux in the core (4) which in turn produces axial heating currents in the cylinders (2 and 5). The inner cylinder (5) may have heated fins (3). An alternative embodiment has an inductively heated screw.

An electrolytic cell, particularly for use with very dilute solutions, has an apertured or rough surfaced electrode and a fluidised bed of non-conducting particles adjacent said surface, the particles being of such size that they pass through the apertures or enter between the peaks or protrusions of the roughened surface.
