摘要： PROBLEM TO BE SOLVED: To obtain a quake-free rubber composition having high attenuating properties, by making the composition include an unvulcanized rubber, a telomer and a vulcanizing agent. SOLUTION: This composition includes (A) an unvulcanized rubber (a natural rubber, an SBR, an NBR, a BR or the like), (B) a telomer having 2,000-8,000 number-average molecular weight (e.g. one synthesized by using trichloro acetic acid, carbon tetrachloride or the like as a telogen and acrylic acid hexyl ester or the like as a taxogen and (C) a vulcanizing agent. In the composition, 1-15 pts.wt. of the component B is mixed with 100 pts.wt. of the component A. In vulcanization using the components, carbon black is added to the components to improve the properties of a vulcanized rubber.

摘要： PROBLEM TO BE SOLVED: To obtain a rubber exhibiting high damping properties, a high breaking elongation and a high breaking strength comprising a rubber containing ethylene groups and a side chain which is bonded to the rubber and bears a silanol on its end. SOLUTION: The titled rubber is constituted of a rubber containing ethylene groups and a side chain bonded to thereto and bearing a silanol, preferably a pyridinium salt of silanol, on its end. That is, the side chain of the rubber bearing a silanol is preferably such that the silanol is bonded to the pyridinium salt. As the rubber containing ethylene groups can be mostly employed a synthetic rubber (e.g. SBR, NBR and the like) which contains ethylene groups and can copolymerize with a vinylpyridine or the like. The rubber is prepared by quaternalizing with an alkyl halide a pyridine ring present in the side chain of the synthetic rubber modified with a vinylpyridine and replacing the halogen in the resultant quaternary salt with a silanol obtained, for example, by the acid treatment of water glass.

摘要： PURPOSE:To enable an appropriate tension to be applied to a belt and reduce moving resistance of the belt, by providing a means for applying a tension to the belt, restricting the position of the belt in transverse directions by flanged pulleys turnably supported, and restricting the position of the belt in only vertical directions by other guide members. CONSTITUTION:In a tractor feeder 5, a head part 29a of a screw 29 fixed to an eccentric cam 27 is turned by a tool such as a screw driver, whereby a guide block 25 is pushed outward according to the quantity of eccentricity of the cam 27, and an arbitrary tension can be applied to a belt 33. By tightening a lock nut 31 in engagement with the screw 29, the cam 27 can be fixed at an arbitrary position. Guide plates 21, 22 and a guide part 26 are not provided with flanges, but a driving pulley 12 and pulleys 23, 24 are provided with respective flanges, whereby the belt 33 can be sufficiently restrained from deviating in transverse directions.
