Abstract: A tooth filling material of powder and liquid is described, essentially consisting of a mixture of the following ingredients: A) an organic, self-hardening component and B) an inorganic component that involves a curing reaction with the formation of crystals and expansion, C) water, with the characterizing property that, after mixing, the mixture remains plastically deformable in a processing time of 2 to 5 minutes and then hardens within 10 to 15 minutes.

Abstract: An electrode for an electrochemical cell used in strip coating systems for continuous metal sheets has a plate-shaped electrode carrier, to which activated electrode components are connected mechanically in a detachable manner. The electrode carrier contains a metal core of material with good electrical conductivity, which, with the exception of the points where the activated electrode parts are connected, is surrounded by a jacketing of valve metal; on the side of the electrode carrier facing the cell wall, a corrosion- resistant plastic body in attached, against which the support means, the spring elements, the positioning elements, or the flow guide elements extending from the cell wall rest, these supports or elements thus being unable to cause any damage to the valve-metal jacketing of the electrode carrier.
