Abstract: A convertible winch, comprises a basic body, motion transmission and reduction elements for the manual and powered operation, with a mono-direction rotation, and manual or powered operation according to at least two directions, with different rotation speed, and a central hole for the insertion of manual operation elements, the motion transmission and reduction elements providing at least a central gear, a lower gear, and a slidable side gear, coupling, by pawls, with the central gear or with the lower gear, determining the rotation according to different speed in function of the rotation direction of the manual or powered operation elements, the winch further providing, inside the body, an element interacting with the slidable gear, on which an operable button removably acts, inside the insertion central hole of the manual operation elements the interaction element being able to take two positions.

Abstract: The present invention relates to a convertible winch (A), comprising a basic body (1), motion transmission and reduction means (5; 5′, 5″), for the manual and powered operation, with a mono-direction rotation, and manual or powered operation according to at least two directions, with different rotation speed, and a central hole (4) for the insertion of manual operation means, said motion transmission and reduction means (5; 5′, 5″) providing at least a central gear (5′), a lower gear (5″), and a slidable side gear (21), coupling, by pawls (19, 20), with said central gear (5′) or with said lower gear (5″), determining the rotation according to different speed in function of the rotation direction of the manual or powered operation means, said winch (A) further providing, inside said body (1), means (18) interacting with said slidable gear (21), on which a operable button (14) removably acts, inside said insertion central hole (4) of the manual operation means (18

Abstract: A reduced size apparatus for centrifugal separation, has a housing, a motor coupled to the housing, and a cartridge in the housing. The cartridge is coupled with and rotated by the shaft of the motor. A feeding channel carries liquid into the cartridge. A second channel extends from the upper region in the cartridge through the rotary shaft to a third channel for ejecting the liquid.
