Abstract: Consumer battery which comprises an electricity generating unit (EGU) 100 and a fuel carrying unit (FCU) 200 that form a passive tubular fuel cell. The EGU comprises an outer tubular collector 130 and an inner tubular collector 140, so that the parts of the EGU are arranged between both collectors and the inner collector applies an outward pressure on said parts. The EGU also comprises two adjacent electricity generating tubular cells 110 and 120 that are connected in series and that can be arranged either consecutively or concentrically. Each tubular cell comprises a proton exchange membrane that, on each side, has a catalyst and a gas diffuser, and also comprises two or more cylindrical seals for sealing the cell and preventing gas leakage.

Abstract: A safety device in hermetic seals in electrochemical cells of the type having a general construction comprising a metallic container (1), in which the active materials which constitute the anode (2) and the cathode (3) are separately contained, characterised in that facing the lower surface of the cover (5), the plastic part (4) has an upper surface with three channels (12) arranged radially at 120° and formed by a reduction in the nominal and normal thickness of the material of the plate (4) which is comprised between the weakened section (10) and the peripheral wall (7); this reduction is progressively greater towards the centre of the plastic part (4) and determines a gradual reduction in the thickness of the annular base (8), or an increasing depth of the channels (12), in the direction from the peripheral wall (7) towards the core (6), the smallest thickness of the annular base (8) being slightly greater than the thickness of the weakened section (10).

Abstract: Zinc alloy for use in an alkaline battery, the alloy including aluminium, bismuth, indium, magnesium, strontium and optionally lead, besides the unavoidable impurities in the aforementioned metals. The alloy can be made by adding pre-alloys of some of the alloying elements or of zinc. The alloy proves useful in reducing the hydrogen gas evolution of the battery.

Abstract: An electrochemical element or cell and a cathode for same which contains an anode, a separator, and a cathode composed of manganese dioxide; this cathode incorporates an inorganic crystalline additive of tungsten oxide, compounds of zirconium, titanium oxide with rutile structure, yttrium oxide, cerium oxide, zeolites and aluminosilicates, and at least one of these is present in a proportion or range between one ten thousandth (0.0001) and ten (10) percent by weight of the cathode mass.

Abstract: Signal light having first and second identical electrical cells, each having the necessary capacity to last for a standard operating cycle. The cells are electrically connected by means of a bistable switch to an electronic control circuit in stable alternative and nonalternating fashion until they are individually depleted. The electronic control circuit has one output connected to one corresponding signal light and another two outputs connected to individual light indicators which are light emitting diodes respectively assigned to the first and second electrical cells and activated by the electronic control circuit when the latter detects a depletion of the electrical energy of same.

Abstract: Display package for electric batteries, constituted by the glued assembly of two parts of recyclable cardboard sheet, comprising, as a first part, a supporting plate (1) provided with a suitable eyelet (6) for being hung up, and as a second part a parallelepipedal receptacle (2) containing the batteries (7) and glued to the front, the lateral vertical walls (2b) of said parallelepipedal receptacle (2) each forming at their lower ends vertical prolongations (3) which extend until reaching the lower edge (1c) of the supporting plate (1) with which they cooperate in forming a base that is orthogonal to the supporting plate (1) and which makes it possible for the package to be self-supporting in the vertical position.

Abstract: In the zone of coupling between the reflector body and the battery body of the signal, the general switch is accommodated, and connected with it is a displaceable element that follows the operating motion of said switch, so that when the latter is in the on position, the displaceable element opens the vents of the battery situated on the upper face of same, and vice versa.

Abstract: A contact assembly for use in alkaline electric cells, includes a inner metal disk and an outer metal disk which engage one another coaxially when embedded in a cell end cover to form a cell anode. The inner metal disk has a neck-like cylindrical projection having an axial bore, the projection extending inwardly of the cell. One end of a collector rod within the cell is seated within the bore of the projection so as to remain in electrical contact with the inner periphery of the projection and, thus, with the anode formed by the two metal disks, in the event the anode is caused to move outwardly of the cell in response to gas pressure developed within the cell.
