Abstract: A high pressure tube compression fitting/flared fitting for use in combination with a thick-walled tube and a connection body wherein a sleeve is in engagement with a thick-walled tube. The sleeve is generally cylindrically shaped with the exterior thereof coated and then etched. The sleeve includes a first and second sharp inner circumferential biting edges which interengage and bite into and through the exterior of the end portion of the thick-walled tube and into the wall portion of the end portion of the thick-walled tube without narrowing the passageway through the thick-walled tube. The process for making the fitting includes placing an end portion of the thick-walled tube into engagement with a tube engaging surface of a tapered generally cylindrical wall of a guide rod.

Abstract: A high pressure tube compression fitting/flared fitting for use in combination with a thick-walled tube and a connection body wherein a sleeve is in engagement with a thick-walled tube. The sleeve is generally cylindrically shaped with the exterior thereof coated and then etched. The sleeve includes a sharp annular biting portion engaging the thick walled tube. The sleeve further includes an inner annular symmetric concavity which engages the thick-walled tube upon deformation thereof. The thick-walled tube includes a flared end portion. A gland about the thick-walled tube engages the sleeve forcing it into engagement with the frusto-conical portion of the connection body coupling the tube, tube fitting and connection body together. The flared end of the thick-walled tube interengages and seals the frusto-conical portion of the connection body.

Abstract: 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.
