Abstract: This invention relates to a method for applying a tread to a tire, whereby around a toroidal tire a layer of non-vulcanized rubber is applied, which will form the tread area of the tire after vulcanization in the vulcanization press; and whereby the thus prepared tire is vulcanized in vulcanization press. According to the invention, before the vulcanization of the thus prepared tire in a vulcanization press, portions of the layer of non-vulcanized rubber are removed by peeling or by forming peels of non-vulcanized rubber, so that the shape of the peeled tire is adapted to the shape of the vulcanization press. The invention also relates to a machine for carrying out the method according to the invention.

Abstract: In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheral zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending-unbending operations in considerably different planes and simultaneously tensioning the cable.

Abstract: A process for manufacturing uranium dioxide powder which comprises forming fine uranium dioxide powder having a high sinterability and coarse uranium dioxide powder having a low sinterability continuously in one process by changing periodically the precipitation condition of the ammonium diuranate under the same condition of calcining and reducing of the ammonium diuranate. The thus obtained mixture of these uranium dioxide powders is suitable for uranium dioxide pellet which is a fuel of nuclear power reactor.

Abstract: A process for treating a radioactive liquid waste is disclosed, in which a radioactive liquid waste containing uranium and .beta.-decay nuclides, daughter nuclides of uranium, is treated by combination of a flocculation method using water glass as pretreatment and a subsequent ion exchange method. An approximately total amount of the uranium and a part of the .beta.-decay nuclides, daughter nuclides of uranium, in the liquid waste are captured by an amorphous silica precipitate formed by addition of the water glass and a remaining part of the .beta.-decay nuclides, daughter nuclides of uranium, is captured thereafter by the ion exchange treatment. The thus captured radioactive materials are respectively eluted from the filtered out precipitate, a radioactive solid waste, and the ion exchanger by acid treatment to be recovered as an acidic solution. Thus, the radioactive materials in the liquid waste are recovered approximately completely, thereby making the radioactivities of a final drain remarkably reduced.
