Abstract: At least one compound defined by one of the following formulae: ##STR1## where X represents Cl, Br, ##STR2## NHSO.sub.2 CH.sub.3, ##STR3## or --SCH.sub.3, and n is 1 or 2; andCH.sub.3 SO.sub.2 NHCH.sub.2 CH.sub.2 CN (II)have been administered to animals to improve the efficiency of food utilization by these animals. These compounds can be administered orally by combining the compounds with feed compositions and fed to animals such as ruminants with a developed rumen function as well as other animals that ferment fibrous material and vegetable matter in the cecum or colon. These compounds effect the rumen metabolism to increase the production of propionate relative to other volatile fatty acids, particularly acetate and to inhibit methanogenesis.

Electrodes with other metal substrates are further provided with such polychelate coatings.

Abstract: An electrode for use in an electrolytic process is provided with a mixed oxide interface between a titanium base and an outer coating. The mixed oxide is formed at said interface by means of titanium from the base and noble metal from a solution containing a predetermined amount of HCl which attacks the titanium base surface. Slow drying provides a metal chloride mixture which is thermally converted to said mixed oxide of titanium and noble metal in a given ratio, whereby to protect the titanium base from oxidation.An outer coating of manganese dioxide or lead dioxide is electroplated on the mixed oxide layer so as to provide an inexpensive electrode with improved resistance to oxidation.This electrode can be used for various processes where a high resistance to oxidation is required, e.g. as a manganese dioxide anode in a metal electrowinning process or as a lead dioxide anode for electroflotation or organic oxidation reactions.

Abstract: An anode with a base of lead or lead alloy is provided with catalytic particles of titanium which comprise a very small amount of platinum group metal or an oxide thereof.These catalytic particles are partly embedded, anchored and electrically connected to the base, so that oxygen is evolved on these particles at a reduced potential at which the underlying lead or lead alloy of the base remains electrochemically inactive, and the anode base thereby serves only as a stable conductive support to the catalytic particles.Operation of this anode at a reduced potential provides energy savings. It may be used more particularly in cells for electrowinning metals with a higher degree of purity at a reduced energy cost with respect to conventional cells equipped with anodes consisting of lead or a lead alloy.
