Abstract: 215,475. Weintraub, E. Feb. 19, 1923. Joint-making packing.-Joints in mercury vapour rectifiers, three-electrode vacuum tubes, vacuum flasks &c., are made by inserting between the surfaces to be joined fusible non- conducting vitric material such as glass or glass enamel the co-efficient of expansion of which is substantially the same as that of the contacting surfaces, and applying heat and pressure. The parts may be heated in a furnace or by induction with high frequency currents. A number of superposed metal plates, which may be staggered or of progressively-decreasing diameter, and glass rings with interposed layers of enamel may be used. A cylinder D, Fig. 1, of porcelain, or refractory glass such as that known under the registered Trade Mark "Pyrex," is pressed between a steel collar C on an electrode and the steel vessel A under heat. A porcelain or fused silica tube F improves the insulation. Glass discs may be interposed between C, D, and A, having coefficients of expansion varying gradually from that of porcelain to that of steel to avoid deformation. Steel, copper, and steel alloys are joined at temperatures from 400‹ to 600‹ C. Tungsten, molybdenum, and ferro-nickel alloys, are joined with the aid of " Pyrex " glass at from 600‹ to 800‹ C. In the construction shown in Fig. 4, plates I, J of tungsten, molybdenum, or ferronickel alloy are welded to the electrode B and vessel A respectively. The electrodes may be welded to rods sealed in glass welded to a metal plate which is welded to the vessel A. The plates may be replaced by cylinders. In Fig. 11, steel rings C of different diameters are shown joined by layers of glass enamel D around an insulating-sleeve F. Copper or ferro-nickel plates coated with crystal glass, or tungsten plates coated with refractory glass may be used. The connections between the extreme plates and the rod and vessel may be spaced to avoid the formation of cracks. In securing an anode to an evacuated metallic vessel, Fig. 12, plates welded by enamel are subjected to pressure by screws D, I, and plastic-metal or asbestos gaskets are inserted between the surfaces where shown. L and M are insulation tubes. The joints between the inner and outer jackets of metallic thermos bottles and in diffusion pumps may be similarly made.

Abstract: 1414697 Fuel elements NUKEM GmbH 1 Feb 1973 [14 Feb 1972] 4991/73 Heading G6C A readily re-processed block fuel element for high-temperature power reactors has fuel and fertile material zones merging directly with a graphite matrix and separated from one another in such a way that, before re-processing, fuel and fertile material zones can be successively separated from structural graphite separately from one another, preferably by drilling, and subjected to a specific working-up process to recover U-233 from the breeder particles and U-235 and fission products from the burnup particles. In one embodiment (Fig. 1A), a central Th-containing fertile zone is surrounded by narrow U-containing fuel zones which in turn are surrounded by cooling ducts. Alternatively (Fig. 1B), a Th-containing fertile zone is surrounded by a narrow graphite zone which in turn is surrounded by a U-containing fuel zone around which cooling ducts are arranged. Fig. 1C shows yet another arrangement in which a cooling duct is surrounded by U- containing fuel zones which are in turn surrounded by Th-containing fertile zones. In all three embodiments, structural graphite is arranged between the individual zones in such a quantity that the zones can be drilled out separately from one another. In an illustrative example, a prismatic block with bores formed in it by means of metal rods is initially hot-pressed from an isotropic graphite granulate and prefabricated cylinders of graphite matrix and coated fuel particles are then introduced into some of the bores. Metal rods are re-introduced into bores required as cooling ducts. The element is finally pressed at elevated temperature to its final size and, following the removal of the metal rods, is subjected to a heat treatment terminated at 1800 C.
