Abstract: Call transfer method for transferring a call in progress between a first terminal (A) and a second terminal (B) by means of a telecommunication network (1), to a third terminal (C), which method includes steps in which: a call (11) is established between the first and the second terminal; the second terminal places the call with the first terminal on hold, and calls a call transfer server (3) connected to the network; once a call (12) is established between the second terminal and the server, the second terminal provides the server with a telephone number of the third terminal; the server transmits an order to establish a call (14) with the third terminal; when the third terminal answers, it is put in communication with the first terminal, and the calls of the second terminal with the network and the call transfer server are interrupted.

Abstract: The magnetic circuit (6) of the stator is suspended from resilient suspension bars (26) which are welded both to floating stiffening rings (30) that are firmly mounted on the magnetic circuit, and to some of the stiffening rings (20) of the outer sheath (18). Other casing stiffening rings (22) have openings to allow the suspension bars to pass freely therethrough, and are equipped with stops to limit rotation of the stator in the event of an electrical fault. There are thus two paths for transmitting force between the magnetic circuit and its surrounding sheath, one of which can be optimized for damping the vibrations of normal use, while the other can be optimized for avoiding damage under fault conditions.
