摘要： A disclosure is made of a subterranean connecting method and a connecting apparatus therefor which are suitable for use when two shield machines are used to excavate a pair of tunnel sections from both ends of a tunnel, and the tunnel sections are connected to each other in mid course. During underground connection, it is important to secure sealing and water retarding with respect to soil and water pressure exerted by the ground in the vicinity of the connecting section. For this purpose, in the connecting apparatus, a penetration ring is arranged in one of the shield machines, and a penetration chamber in which the penetration ring is accommodated is arranged in the other shield machine. Both the both shield machines face each other with a slight gap remaining therebetween and, subsequently, the penetration ring is moved forward and penetrates into the penetration chamber of the mating shield machine. By this penetration, the area between both the shield machines are closed by the penetration ring. In this condition, both the shield machines are disassembled, and the wall surface of the connecting section including the penetration ring is covered, so completing the subterranean connecting step. According to the connection using such a penetration ring, sealing and water retarding with respect to the soil and water pressure in the vicinity of the connecting section can be secured.

摘要： A preformed yarn useful for forming composite articles is disclosed which includes a core of a multiplicity of fibers, fine powder provided in the interstices between the fibers, and a flexible sleeve formed of a thermoplastic resin and surrounding the core. The fine powder is formed of a material which neither melts nor reacts with the thermoplastic resin at a temperature up to 450.degree. C. and at a temperature up to the melting point of the thermoplastic resin. The incorporation of the fine powder between the fibers is effected by injecting fine powder-containing air from a jet nozzle and blowing the air against a bundle of the fibers.

摘要： A continuous process for the production of carbonaceous pitch, including heat-treating an aromatic heavy oil in a first thermal cracking zone for obtaining a first cracked product, and introducing the first cracked product into a second thermal cracking zone where it is thermally cracked by direct contact with a gaseous heat transfer medium to form distillable cracked components and a mesophase-containing pitch. The liquid phase in the second thermal cracking zone, including the mesophase-containing pitch, is discharged therefrom and separated into a mesophase-rich pitch and a matrix pitch having a low concentration of mesophase. The mesophase-rich pitch is recovered while at least a portion of the matrix pitch is recycled to the second thermal cracking zone. The distillable cracked components are stripped from the liquid phase in the second thermal cracking zone with the heat transfer medium, and the resulting gas phase is withdrawn overhead therefrom and then separated into a light fraction and a heavy fraction. The heavy fraction is fed to the first thermal cracking zone.
