Abstract: A reversible converter includes a first field effect transistor and a second field effect transistor coupled in series between a first terminal and a second terminal for a DC voltage. A first thyristor and a second thyristor are coupled in series between the first and second terminals for the DC voltage. A third thyristor and a fourth thyristor are also coupled in series between the first and second terminals for the DC voltage terminals, but have an opposite connection polarity with respect to the first and second thyristors. A midpoint of connection between the first and second field effect transistors and a common midpoint of connection between the first and second thyristors and the third and fourth thyristors are coupled to AC voltage terminals. Actuation of the transistors and thyristors is controlled in distinct manners to operate the converter in an AC-DC conversion mode and a DC-AC conversion mode.

Abstract: A method for manufacturing a stopper for closing a neck of a container comprises a first step of molding the stopper in one piece. The stopper includes a sealing membrane provided with a central opening, a tubular stem centered on an axis and extending from the sealing membrane around the central opening, and a capsule connected, by a tear wall, to a free end of the stem. The capsule is configured to be wedged in the stem to seal the neck of the container. The method comprises a second step in which, while the tear wall is intact, a force, in line with the axis, is applied to the stopper so as to break the tear wall and move the capsule inside the stem until the capsule is wedged in the stem.
