Abstract: A timepiece mechanism includes a first energy source with a regulating member, a second independent energy source, a control member driven by the second energy source, and a blocking device controlled by the first energy source to block the second energy source and release it to allow the control member to be displaced by jumps powered by the second energy source. The blocking device includes first and second mobile parts kinematically interconnected, the first mobile part including a drive device, the second mobile part including a stopping device; a rotating drive member connected to the first energy source and cooperating with the drive device to displace the mobile parts, alternately in opposite directions; and a rotating blocking member connected to the second energy source and cooperating with the stopping device to be blocked by the second mobile part and released at the determined times by second mobile part movement.

Abstract: Disclosed is a display mechanism for a timepiece, including a frame, an aperture which is fixed relative to the frame and a first and a second display disc each bearing indications, characterized in that it makes it possible to display the indications of the first and second discs alternately through the aperture. The invention also relates to a timepiece movement including such a mechanism, and to a timepiece such as a wrist watch, a pocket watch, a clock or a miniature clock including such a timepiece movement.

Abstract: Disclosed is a timepiece blocking device including first and second mobile parts kinematically connected to one another, the first mobile part including a drive device, the second mobile part including a stopping device; a rotating drive member turning in a single direction and cooperating with the drive device to displace the first mobile part, and thus the second mobile part, alternately in opposite directions; and a rotating blocking member tensioned and cooperating with the stopping device to be blocked by the second mobile part and released at determined times by the displacements of the second mobile part. Cooperation between the rotating blocking member and stopping device immobilizes the mobile parts when the rotating drive member does not cooperate with the drive device. In normal operation, the rotating drive member contacts the first mobile part only when cooperating with the drive device, i.e. over less than 60% of one revolution of the rotating drive member.

Abstract: Cartridge unit for an electrochemical sensor includes a cartridge (2) prefilled with electrolyte and having a first end closed by a selectively permeable membrane (7), and a second end (6) having a fastening device (11) arranged for fastening the cartridge to the electrochemical sensor (24). The cartridge unit further has a supporting member (3) to which the cartridge (2) is detachably fastened, and closing devices (4, 20) for closing the second end (6) of the cartridge (2). These closing devices (4, 20) are able to be opened by a user to allow the cartridge (2) to be fastened to the electrochemical sensor (24) and then to be detached from the supporting element (3).
