Abstract: A bottle cap removal torque sensor including a rotate motor for rotating a chuck engageable with the cap of a bottle, a support for fixing the bottle with respect to the axis of the chuck, an axial pressure supply mechanism for pressing said chuck against the bottle cap, and a torque sensor for measuring the torque applied by the motor to the bottle cap.

Abstract: An apparatus for internally electropolishing tubes in which a plurality of elongate tubes are horizontally supported and rotatably driven about their length axes. An outlet fitting including an end dam permits rotation of the tube outlet end therein, allows escape of gases from the upper portion of the tube, and permits overflow of electrolyte liquid thereover and fixedly supports the end of a cathode rod. The cathode rod is formed as two aligned, axially adjacent partial length sections. The positive terminal of an electric current supply connects at a plurality of points to the tube along its length and connects at its negative terminal individually to the outer ends of the two cathode sections.

Abstract: An apparatus for the preparation of sterile suspensions and solutions is disclosed which includes a container wherein a starting mixture is subjected to high intensity mixing by means of a high speed, high shear external mixer disposed in an external recirculation loop. The mixer used in the present invention is a revolving hollow cylinder open at the bottom thereof and having grooves in the sides thereof, such that the mixture is drawn through the bottom of the mixer head and forced radially outwardly through the grooves. The mixer head is preferably disposed in the upper leg of a T-shaped fitting of the recirculation loop, and a special shaft seal is used to prevent leakage of the materials being treated along the drive shaft used to rotate the mixer head.
