Matrix material for regenerators
First Claim
1. A matrix material for regenerators, comprising a plurality of screen meshes, each of which consist of a stable basic mesh, with wire diameters between 0.005 and 0.015 mm and of a lead sheathing with a thickness of 0.025 to 0.075 mm, is layered into a stack.

Abstract
A matrix material for regenerators, comprises a stable basic mesh with wire diameters between 0.005 and 0.015 mm and a lead sheathing with a thickness of 0.025 to 0.075 mm. This lead screen mesh can be stacked very easily to form a matrix material. In order to form the mesh, an available fine-mesh metallic screen mesh, for example, of brass, bronze, or high-grade steel, is etched by a wet chemical or electrochemical means, until the mesh has been thinned down to the required wire thickness of between 0.005 an 0.015 mm. Subsequently, this thinned-down mesh is electroplated with lead up to the desired technological mesh width, or is coated with a lead layer that is 0.025 to 0.075 mm thick.

4. A method for producing a fine-mesh lead-sheathed screen for use as matrix material of regenerators, comprising thinning a stable wire screen mesh down by electrochemical or wet chemical means to a residual wire thickness of less than 0.015 mm, and subsequently electroplating the thus thinned mesh with lead up to the required layer thickness.
