Abstract

<PICT:0746806/III/1> <PICT:0746806/III/2> An electric resistance element is provided with a thin adherent film of a catalytically active inorganic oxide, e.g. alumina, beryllia, zirconia, thoria, magnesia or mixtures of these oxides. The oxide may be impregnated with finely diided catalytically active metal, e.g. platignum, ruthenium, palladium, silver, copper, nickel, chromium, cobalt or mixtures of these. The element is coated with the oxide by dipping into a slurry formed by reducing the oxide to an extremely finely divided state, by grinding in a colloid mill, and suspending in a liquid medium. In a form of the invention an electrical resistance wire 3 in the form of doubly wound coils separated by a non-conductive strip 4, is supported in a cylindrical coil holder 7, which is adapted to telescope into a similar holder as in Fig. 3. The whole is protected from excessive beat losses by an external layer of insulating material 15.
