Abstract: A coupling consisted of a compound carrier mounted on a drive shaft and a ring gear mounted on a driven shaft. Axles, on which planet gears and hermetically sealed hollow drums with inner radial blades are secured rotate freely in the carrier bearings. The drums are partly filled a fluid. The planet gears are inside the ring gear and in ingagement with it. The driven shaft angle velocity ranges from 0 to the drive shaft angle velocity. The coupling transfers a continuously varying torque from the drive shaft to the driven shaft.

Abstract: A device executed in the form of two hinged frames secured together with a hinge axle and fitted with a spring and a squeezing roll, provided with a sleeve. The bottom part of the tube is to be inserted under the squeezing roll; both frames being pressed by fingers are drawn along the length of the tube. The present invention makes it possible to squeeze out practically all the contents of a tube.
