    Abstract: Large-sized and thick compound sleeves of high hardness adapted for use with back-up rolls of the assembly type having an outer diameter of over 1,000 millimeters and produced by centrifugal casting. Each sleeve comprises an outer layer of high-alloyed cast steel having a shore hardness number in a range between 60 and 75 and a carbon content in a range between 0.4 and 0.9% by weight, and an inner layer of low-alloyed tough cast steel having a shore hardness number in a range between 30 and 45. The sleeves are produced such that the ratio of the thickness of each sleeve to the outer diameter thereof is in a range between 0.10 and 0.30 and the ratio of the thickness of the outer layer thereof to that of the inner layer thereof is in a range between 0.40 and 1.2.

    Abstract: 7. A high-power electron discharge rectifier, comprising an anode and a cathode supported in spaced relation thereto, said anode comprising a substantially cylindrical member of plurallayer material defining a barrel portion generally enclosing said cathode and a pair of free ends, said plural-layer material comprising at least one layer of high heat conductivity material disposed to form the surface of the barrel nearer said cathode, whereby to facilitate conductive cooling of said anode and thus to minimize formation of hot spots thereon, and means joining said ends in juxtaposed relation over a portion thereof to define a web, the remote end portions being outwardly flared to provide oppositely extending wings.
