    摘要: A solvent free method for making an ethylene propylene diene terpolymer latex by blending water with 1 weight percent to 50 weight percent surfactant; blending solvent free ethylene propylene diene terpolymer with the water and surfactant at a low pressure to form a terpolymer mixture; high shear mixing the terpolymer mixture at 0.5 atm to 1.5 atm for 5 minutes to 24 hours at a temperature from 20 degrees Celsius to 100 degrees Celsius to form a solvent free ethylene propylene diene terpolymer latex formation, wherein the solvent free ethylene propylene diene terpolymer latex formation has a viscosity from 1 centipoise to 2000 centipoise; a density from 0.8 to 1.1; and a shelf life of from 7 days to 365 days without separating or stratifying.

    摘要: La présente invention concerne une machine à reprofiler les rails usés par fraisage.
    Cette machine comprend essentiellement une première fraise (2) à axe incliné par rapport à la verticale de manière à attaquer tangentiellement la table de roulement (3) du champignon (4) du rail (5), une deuxième fraise (6) à axe vertical pour fraiser simultanément et tangentiellement le flanc usé (7) du champignon du rail, ainsi que des moyens de guidage (8) associés à chaque fraise et se composant d'une paire de galets obliques (10, 11) supportant le dessous et chaque côté du champignon du rail en amont de chaque fraise, et d'une autre paire de galets obliques opposés (10a, 11 a) situés en dessous et de chaque côté du champignon du rail en aval de chaque fraise, tous ces galets étant montés par deux dans un étrier (12) pouvant coulisser verticalement sur un chariot (13) déplaçable horizontalement sur le bâti (9) de la machine.
    Cette machine s'applique à la rectification du champignon de rails de longueur et de type quelconques, avec un rendement élevé.

    摘要: The invention concerns a train for loading, transporting and unloading long welded rails, comprising a plurality of wagons (2) for storing and transporting the welded rails, movable on a track, and an engine (50) provided with two devices (27) for gripping rails that is movable on the train in the longitudinal direction of the wagons, in order to provide traction and to place the rails on said wagons. The train is characterised in that the movable engine (50) can be moved along a rail device (9) disposed on top of the platform (7) of the wagons (2). The invention can be used for loading, transporting and unloading long welded rails.
