    Abstract: A paste composed of glass having a low fusion point and metal powder is fired on a ceramic material to form a very thin metallic film thereon. A metal body of easily deformable shape is then sandwitched between this film and the metal material to which the ceramic material is to be bonded and the contact points on either side are bonded to the respective materials by firing. The bonded ceramic-metal body so formed is stable in it''s mechanical, heat and electrical properties and is especially adaptable for use as the oxide electrode in MHD power generation.

    Abstract: A composition is produced by combining one or more members selected from the group consisting of cinnamic acid-vinylphenyl ester, cinnamic acid-isoalkenylphenyl ester, and homologs thereof, styrylacrylic acid-vinylphenyl ester, styrylacrylic acidisoalkenylphenyl ester and homologs thereof with a cationic polymerization catalyst. This composition is polymerized or copolymerized to form a novel photosensitive product. The product thus obtained is a linear polymer or copolymer in which only the vinyl group or isoalkenyl group is polymerized and the photosensitive group is quantitatively retained in the side chain. The polymer of copolymer has a high degree of photosensitivity and permits photosensitizing reaction to occur uniformly.

    Abstract: In a fluidizing device adapted to effect chemical reaction, heat transfer, material transfer, etc. and provided with a cyclone unit, a plurality of internal members made of bars or tubes are disposed at fixed intervals within a free board section formed above the fluidized bed. When the fluidizing device has the internal members disposed as described within the free board section, agglomerates of constituent particles of the fluidized bed which fly out of the fluidized bed come into contact with the said internal members, with the result that the kinetic energy possessed by each agglomerate of particles is gradually consumed in the course of several contacts and the vertical component of the speed vector of the agglomerate of particles flying toward the cyclone unit is proportionally decreased. Consequently, the amount of fine particles produced due to collision into the inner wall surface of the column is markedly decreased and at the same time the absolute amount of particles flying into the cyclone unit is decreased to a great extent.

    Abstract: Briquets are manufactured by kneading in a hot blow atmosphere coal dust blended with asphalt containing 55-65 percent n-hexane soluble matter as the binder in a particular ratio and molding the kneaded blend under heat-compression. These briquets are further heat-cured in an oxidizing atmosphere and then calcined in an inert gas, to produce coke in the molded form. The resulting products have all the properties required for use in blast furnaces.
