Abstract: In an alkaline zinc cell, provision is made, in order to prevent accumulation of hydrogen gas which is produced by corrosion of the anode zinc, to apply a viscous adhesive with which a catalytically active metal (for example Raney Ni) is admixed, only point-wise to one of the cathode rings. The catalyst, which is at a high positive potential because of its electrically conducting contact with the cathode, absorbs hydrogen and recombines it with high conversion rate to form water. Application of the catalyst-containing adhesive, preferably an active glue, onto the cathode body or onto a cell component (separator, housing can) which is in surface contact with this body can be carried out by means of brushes, drop-application from a syringe or by pad-application. <IMAGE>

Abstract: A combined electric plug connector establishes a combined connection between supply equipment and an electric welding sleeve (M) with an integrated heating component (E) and an electronic information carrier (I) on a printed circuit board (4). The connector is composed of a strong current connector for welding and of a data transmitting, weak current connector. The strong current connector consists of a pin-socket connector, the pin (11) being located in the electric welding sleeve (M) and the socket (81) in a combined plug (B). Plated-through holes (41) located in the printed circuit board (4) may be slid on the pointed, spring-loaded, thin pins (90) of the combined plug (B) in order to establish the weak current connection. As the plug receptacle (2) for the weak current connection is directly located in the printed circuit board (4), the size of the combined plug receptacle (A) in the electric welding sleeve (M) is limited to a minimum, so that production is simple and economical.
