摘要： A high temperature and high pressure consistometer comprises a cylindrical pressure vessel having an integral bottom and a cover for said pressure vessel. A nonmagnetic canister extends downwardly from said bottom and is sealed therein. A driven magnet assembly is journaled in said canister. A drive shaft is connected to said driven magnet assembly extending into said vessel. A nonmagnetic canister extends upwardly from the cover and is sealed therein. A driving magnet assembly is journaled in said canister. A shaft connected to said driving magnet assembly extends downwardly into said vessel. A driven magnet assembly is mounted for rotation on the exterior of the downwardly extending canister and a driven magnet assembly is mounted for rotation on the exterior of the upwardly extending canister. A sample cup is connected to the upwardly extending drive shaft and a paddle is connected to the downwardly extending shaft. External the vessel is positioned an instrument for measuring the torque magnetically transferred from the shaft carrying the paddle to the driven magnet assembly. External the vessel is a motor for causing the driving magnet assembly to rotate at a constant speed to thereby drive the cup within the vessel at a constant speed.

摘要： A rising stem valve comprising a valve body, a two part valve stem and a stem guide washer. The valve body has a valve seat in a passage between an inlet and outlet port. The two part valve stem comprising a rotating stem and a non-rotating stem and the rotating stem has a threaded bore receiving a threaded end of the non-rotating stem. The non-rotating stem has a non-circular cross section external of the threaded bore and is adapted to carry a closure head to the valve seat. The stem guide washer has a bore positioned in mating relationship with the noncircular cross section of the non-rotating stem, whereby the stem guide washer prevents the stem from rotating when the upper stem is rotated.
