  • Publication number: 20040012121
    Abstract: A process for making a fiber reinforced molded article is disclosed. The process entails (i) melting a thermoplastic resin (ii) introducing and homogeneously distributing at least one fiber strands to the molten resin to form a mixture of fibers and molten resin and (iii) molding the article by injection or by compression molding, and (iv) solidifying the article. The process is characterized in that where the fiber strands have a fiber length of 2 to 25 mm and in that the molded article contains fibers the mean length of which is at least 400 &mgr;m. Lastly the process is characterized in that no cooling or solidifying take place between steps (ii) and (iii).

  • Publication number: 20030221923
    Abstract: A hydraulic dashpot comprises, first, a cylinder and a piston. The cylinder (1) is charged with shock-absorbing fluid. The piston (3) is provided with ports and valves, is mounted on one end of a piston rod (2) and divides the cylinder into two chambers. The piston rod travels into and out of the cylinder and is provided with a central bore (20). The dashpot also comprises an adjustable bypass accommodated inside the piston rod or inside an extension (7) thereof. The bypass is provided with radial outlets (19, 23, 37) through the piston rod or extension. The cross-section of the bypass during the compression phase can be established independent of its cross-section during the suction phase and vice versa. There are two valves in the end of the piston rod near the piston or in the piston-rod extension. Each valve is provided with a rotating plunger (18, 21, 32, 33) with a rotary connection. Each plunger operates in conjunction with a radial inlet or outlet (19, 23, 27).
