Abstract: A crank and linkage assembly for a component of a turbocharger includes a linkage and two cranks each including a pin whose outer surface defines a pin groove. Each end of the linkage defines a through bore for receiving one of the pins. At each end of the linkage, a plurality of fingers are integrally formed and of one piece with the linkage, the fingers extending parallel to, and circumferentially spaced about, the through bore axis. The fingers are elastically bendable such that the hooks move away from the bore axis and such that a restoring force of each of the fingers acts in a direction to bend the hooks back toward the bore axis. The assembly can be assembled by a push-to-connect process in which each pin is advanced into the respective through bore until the hooks snap into the respective pin groove.

Abstract: Variable transmission gear particularly for bicycles comprising a transmission element such as a chain or a belt which is in engagement with a driving and a driven rosette, one rosette consisting of two parts adapted to be mutually shifted along straight guidings, the axis of said guidings being parallel and passing beyond the axis of supporting shaft.
