A load-bearing thermal insulator, for example a brake piston thrust transmission element, which comprises platelets or flakes of thermally insulating material dispersed in a metal matrix and oriented normal to the direction of heat flow so as to impede the flow of heat through the matrix in one direction.

A process is provided for making a solid precursor of a solution of cellulose in a tertiary amine oxide by suspending cellulose in a mixture containing a tertiary amine oxide and water under conditions where the amine oxide will not dissolve the cellulose until sufficient amine oxide has been absorbed to dissolve the cellulose when it is heated. An organic liquid which is not chemically reactive w...

In a fluidized bed reactor total gas feed is through a constricted opening at the bottom of the reactor. A carrier gas supply duct communicates with said bottom. A reaction gas supply tube, disposed within said duct, has an outlet spaced from said bottom and is comprised of a bundle of tubes arranged to dispense an annular stream.

It is the object of the invention to combine in one method the advantages of the powder-metallurgical production and the melting-metallurgical production of materials for contact members of vacuum switches from CuCo, CuFe or CuCr alloys. This is brought about in that CuCo, CuFe or CuCr melt, which latter is in two phases, is degassed, deoxidised and atomised. Depending on the composition of the po...
