    摘要： A process for finishing a hydrogenated diene polymer by producing porous pellets from a water slurry of the hydrogenated block copolymer. The process comprises adjusting the water content of the slurry to from 9 to 16 percent by weight, moving the slurry through a mechanical two-stage extruder dryer, drying the slurry at a temperature of 100 to 180° C., and recovering porous copolymer pellets having a moisture content of 0.2 to 3.0 percent by weight.

    摘要： A unique hand wheel engagement/disengagement mechanism for a brake lathe employs a single slide drive motor which drives a drive shaft that provides a power supply to multiple lead screws. The mechanism includes a hand wheel tube which has a compression spring contained within the tube. A push button is also located within the hand wheel tube. The push button has a base which captures the compression spring between the base and the end of the drive shaft. The compression spring causes pressure against the face of the base to push it away from the drive shaft when the system is in its normal, at rest position. The push button includes a shank extending between head of the push button protruding from the hand wheel tube and its base. The shank has a shoulder which reduces the diameter of the shank to create a recess within the hand wheel tube. A pin passes through diametrically opposed holes in the hand wheel, which are in registry with similar diametrically opposed holes in the hand wheel tube, and through a slot in the shank. The slot allows the button to move axially in and out of the hand wheel tube a distance of approximately 1/2" so that the drive shaft will engage one lead screw in one position and another lead screw in the other position in order to permit the machine to be changed from one configuration to another and manual adjustment in either position.
