    摘要: An imine compound is produced in high yield by reacting a benzophenone with ammonia in the presence of 0.01 to 100% by weight of an oxide of at least one of metals selected from the group consisting of metals of the second to fifth periods of Group III to V of the periodic Table, and iron as a catalyst at a reaction temperature of 150.degree. to 250.degree. C on the basis of benzophenone. Ammonia is fed to the reaction system continuously under a pressure of 2 to 15 atmospheres. A solvent may be used for the reaction. The catalyst metal oxide can be readily recovered and reused without any influence of water formed by the reaction.

    摘要: A plurality of agitation spindles are disposed, and an agitation vane is attached to the lower portion of each agitation spindle. A mixing and kneading zone for mixing and kneading soft soil with a hardener is formed so that the hardener is supplied near these agitation vanes. The agitation spindles are supported by reinforcing members and connecting members to construct a multiple spindle kneading apparatus for improving ground. In one embodiment, blade-like excavating cutters are mounted on the agitation spindles. In another embodiment, hollow agitation spindles are used and the hollow portions are used as hardener passages. In still another embodiment, a tube for injecting the hardener into the mixing and kneading zone is disposed so that it can be moved up and down. A method for hardening soft ground by using this multiple spindle kneading apparatus in which the hardener feed position can be changed is provided.

    摘要: Sludge deposit is stored in a sludge deposit receiving hopper, and the stored sludge deposit is fed onto a belt conveyor and transferred to a mixer. A hardener is fed to this mixer from a hardener hopper. A conveyor belt is disposed on the belt conveyor to measure the quantity of the sludge deposit transferred by the belt conveyor. According to this measured value of the transferred sludge deposit, the quantity of the sludge deposit fed from the sludge deposit receiving hopper and the quantity of the hardener fed from the hardener hopper are controlled. The sludge deposit is mixed and kneaded with the hardener, and the sludge deposit is solidified.
