Abstract: A device (1) for use with a battery carrier (10) defining at least one sealed compartment (12) in which a product (14) is located and which is at least partly formed of a frangible material (20), the device (1) having a support for supporting the carrier (10) with the compartment (12) aligned with an aperture (8) in the support, and an engaging device for engaging with the compartment (12) whereby to break the frangible material (20) and displace the product (14) from the compartment (12) through the aperture (8). The support and the engaging device are normally spaced apart but are relatively movable to effect product (14) displacement, the support including at least one prong (15, 16) arranged in the aperture (8) in order to break the frangible material (20) when the engaging device displaces the product (14).

Abstract: A cell includes a case designed to form a housing, an assembly of stacked electrodes placed inside the housing and including one or more units each having a positive electrode, a negative electrode, a separator between the positive and negative electrodes and an electrolyte. The assembly is held together, and at least each negative electrode of the one or more units includes one or more notches, vertically aligned along the height of the assembly so to design a substantially flat contact surface.

Abstract: An electrically conductive holder is provided that is suitable for receiving a tablet electrode of a button battery. The holder includes a bottom portion to be fitted coaxially within terminal of a button battery. The holder further includes an upstanding wall portion. The bottom portion is flat and provided with a plurality of apertures through the complete thickness of the bottom portion. At least one group of apertures is distributed at regular angular intervals around the center of the bottom portion, spanning 360°. The strips of solid material of the bottom portion between two adjacent apertures are preferable narrow compared to the dimensions of the adjacent apertures so as to provide a mechanical support for the tablet electrode while also being able to deform under the influence of a volumetric expansion of the electrode.

Abstract: A battery-operated wristwatch includes a watch case, two strap parts and a clasp, wherein a battery housing including a battery is integrated in the clasp. One of the strap parts includes power transmission wires. The battery housing is coupled to the power transmission strap part by a first coupling that allows the transmission of a power signal. Likewise, the power transmission strap part is coupled to the watch case by a second coupling that allows the transmission of the power signal from the battery to the watch case. Particular embodiments are related to a watch provided with a deployable clasp comprising clasp portions which can be folded together, and wherein the battery housing is attached to one of the clasp portions.
