Abstract: A pressure compensation device for a battery housing includes a base body fluid-tightly connectable to an edge of a pressure compensation opening of the battery housing, and including a gas passage opening, a closure cap configured to, when a predetermined pressure difference between an interior space of the battery housing and an environment of the battery housing is exceeded, deflect in an axial direction from an initial position in a normal operating state of the pressure compensation device to transfer the pressure compensation device into an emergency degassing state, and a ramp fastening device configured to connect the closure cap and the base body, and including a ramp body disposed on the base body and extending in the axial direction, the ramp body including ramps on sides of the ramp body and facing away from one another in a radial direction.

Abstract: An assembly for a dispenser includes a front plate having a first tube aperture configured for securably receiving a tube within the aperture, the tube being configured to receive a container having a flowable material; a release assembly disposed on the front plate having first and second members hingingly movable about a hinge portion on each of the first and second members for partially covering the first tube aperture when the first and second members are in a closed position and for uncovering the aperture when the first and second members are in an open position. A combination includes a dispenser and the assembly releasably secured to the discharge gun. A kit includes a container having a flowable material; the dispenser having plunger; and the assembly releasably secured to the discharge gun.

Abstract: A method for manufacturing a miniaturized electrochemical cell and a miniaturized electrochemical cell is provided. The method includes the following steps: a) forming a colloidal template of colloidal particles made of an electrically insulating material, on a substrate made of an electrically conducting material, b) depositing by electrodeposition in the void spaces of the colloidal template, at least three alternating layers forming a repeating unit, the alternating layers being made of an electron conducting material or a semi -conducting material, the intermediate layer(s) being made of a material M3 different from materials M1 and M2 constituting respectively the upper and lower layers, the material M3 having a standard potential lower than the standard potentials of the materials M1 and M2, c) removal of the material M3 of intermediate layer(s), and d) removal of the colloidal particles of the upper and lower layers to obtain the desired electrodes.
