Abstract: A turret lathe includes a bed, a headstock mounted on the bed, a first slide mounted slidably on the bed, a second slide mounted slidably on the first slide, a spindle journalled to the headstock, a chuck mounted on the spindle, a tailstock mounted on the second slide, a driven shaft journalled to the tailstock, a turret mounted on the driven shaft, a transmission unit, and a clutch operable between a chamfering operation mode, in which the driven shaft is connected to the spindle through the transmission unit, and a turning operation mode, in which the driven shaft is disconnected from the spindle.
Abstract: 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.
Abstract: 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.
