Abstract: The invention pertains to linear electrochemical functional elements which have strip-shaped ion-exchange membranes (IEMs) and/or hydrogen-diffusion electrodes accessible at the ends which are enclosed on all sides in an insulating manner by a jacket of a solid material. The invention describes the structure, production, and use of the functional elements in electrochemical measuring techniques. In one embodiment, a charge state indicator is created by the incorporation of a lead/lead sulfate half-cell into a lead/lead oxide cell. This coupling takes place via a linear functional element in the form of an installed ion-exchanger membrane. It makes it possible to measure three voltage values on the cell and to evaluate them in order to determine the current charge state by conventional methods.

Abstract: Discrete locations of an electrode web or electrode segment based on a porous metallic carrier framework, which are intended to receive the take-off conductor, are briefly heated to about 450.degree. C. and then cleared of active mass with compressed air. The heating, for which a stream of hot air is particularly suitable, has the effect of destroying the organic binder present in the active material. Following such treatment, a clean metal surface is made available for the welded attachment of the take-off conductor, of a size which is limited to the precise dimensions necessary for the connection.

Abstract: Viscous active ingredients are introduced into the case of a galvanic cell by extrusion from a nozzle fed with the ingredients by a pumping device. The pumping device includes an elastic, substantially straight piece of hose, and a pressure roll which can be moved along the hose between two established limits, both in the general direction of the outlet nozzle to compress the hose, and in the opposite direction to assume a retracted position along the hose. The piece of hose is compressed at a point immediately adjacent to the hose segment defined between the established limits of the pressure roll so that the material to be metered does not come into contact with parts in relative motion to each other.

Abstract: Positive ribbon electrodes for primary and secondary cells are produced in a dry process wherein two strips of active material in powder form, preferably comprised of MnO.sub.2, FeS.sub.2, CuO, .alpha.-Cu.sub.2 V.sub.2 O.sub.7, and Li.sub.x MnO.sub.y, are simultaneously rolled and then fed into the gap of a roller mechanism, on opposite sides of an interposed metal net or mesh, to roll coat both sides of the lattice-like carrier strip. After excess mass is stripped off, the finished electrode ribbon has a thickness of less than 0.45 mm and a porosity of more than 24% which, because of its large active surface, is advantageously used in wound batteries incorporating Li or H.sub.2 electrodes.

Abstract: A relay driving circuit for a latch-in type magnetic relay having an excitation coil, generating a set current and a reset current of opposite polarity for the coil. A capacitor is provided between the input terminals of the circuit in series with the coil. A set switch is connected in series with the coil and the capacitor, and a reset switch is connected across the series combination. An input voltage level detector is provided to make the set switch conductive, thereby applying the input voltage to the excitation coil and the capacitor to provide the set current. As the input voltage decreases below the trigger level, the detector makes the reset switch conductive to allow the capacitor to discharge current in the opposite direction through the excitation coil.

Abstract: A spiral-wound galvanic cell is based upon a lithium system with a nonaqueous electrolyte, and includes a positive electrode, the carrier of which is clamped within the slit of a simple metal splint which serves as the winding mandrel and current collector. Contact with the metal splint is established by a leaf spring associated with the housing cover, which then serves as the positive terminal post for the cell. A high specific contact pressure is developed at this connection by providing the leaf spring with a punched hole which rests on thicker top portions of the metal splint. A small metal plate pressed through the lithium electrode and its separator establishes electrical contact between the lithium electrode and the interior wall of the housing vessel, which then serves as the negative cell pole.

Abstract: A process which comprises thermally decomposing in an electrically heated vibrating helical conveyor, manganese carbonate (MnCO.sub.3 x H.sub.2 O) into a manganese oxide (predominantly of Mn.sub.2 O.sub.3 x Mn.sub.5 O.sub.8) catalyst at about 500.degree. C., and processing this catalyst into a highly active electrode paste by dry intensive mixing with a carbon-containing conductive material (carbon black, graphite or activated carbon) and PTFE as the binder. The resulting electrode paste can be rolled into a supporting net made from Ni or Ag. Also a two-step mixing process in which the catalyst powder is first premixed with small amounts of a conductive agent and a binder, compacted and granulated, and then combined with the larger residual amount of the intended amounts of conductive agent and binder in a second mixing step.

Abstract: In an air/oxygen button cell the multilayer air electrode is reliably held in place between an inwardly extending rib which is formed in the bottom of the cathode cup and a sealing base which is associated with the cup forming the negative electrode. The sealing base acts like a domed spring under tension because of a sloping portion provided in its bottom in the region above the rib. The air electrode remains flat and is secure against lateral displacements.

Abstract: An electromagnetic relay includes an armature 1 supported in a central longitudinal bore 12 of a one-part bobbin 2 by means of a bearing which includes a first pair of curved bearing surfaces 1a, 1b, formed on the armature 1 and engaging a second pair of supplementarily curved bearing surfaces 2a, 2b, formed in the bore walls. The first bearing surfaces 1a, 1b may be either cylindrical in which case cylindrical second bearing surfaces 2a, 2b are formed in ribs 2c, 2d projecting inwardly from opposite bore walls, or spherical in which case spherical second bearing surfaces are formed directly in opposite bobbin walls.

Abstract: A modular relay incorporated in a plugable element is disclosed. In accordance with the preferred embodiment, the relay is of the bistable type, and in response to actuation, is caused to switch state for a predetermined period of time, thus acting as a monostable device. Structure is disclosed for insuring that the state of the relay is known prior to actuation. A particularly advantageous mounting structure is incorporated within the relay comprising multi-step mounting feet. The energizing circuit in accordance with the invention is disposed within the plug socket.

Abstract: A getter for use in a sealed contact chamber consists of a porous getter material which acts to adsorb substances which could create resistive films on electrical contacts. By disposing such a getter within the contact chamber of a switching device, such as an electromagnetic relay, molecules of, for instance, organic compounds, may be selectively and over long terms adsorbed to the getter and thus kept away from the contacts. The selective adsorption of such molecules is achieved by a porous getter material in which the majority of the pores have diameters greater than 3 nm and smaller than 100 nm, with the mean value of pore diameter ranging from about 7 nm to about 20 nm. The getter material may be substantially Al.sub.2 O.sub.3.

Abstract: In an electromagnetic relay, an armature block serving to actuate contact springs includes a pair of armatures and a permanent magnet disposed therebetween to magnetize the armatures to opposite polarities. Pole ends of a yoke carrying the excitation flux created by the relay coil extend between free ends of the armatures. The armature block is suspended by means of a resilient arm integrally formed with the block at one side thereof and having its outer end fixed to a bearing portion, so that a rocking motion of the armature block is achieved by a flexing motion of the resilient arm.

Abstract: In the continuous manufacture of plastic-cohered gas diffusion electrodes, and particularly air electrodes, in the form of thin foils, a dry mixture of PTFE and active carbon powder is subjected, during the mixing process in a paddle mixer, to the additional intensive influence of rapidly rotating cutting knives. The degree of subdivision and homogeneity of the dry mixture is thereby enhanced to such a degree that, in the finished electrode tape, the mass does not exhibit nonuniform thickening.

Abstract: A polarized electromagnetic relay includes two contact springs extending substantially parallel to each other.One of the contact springs forms a movable contact for cooperation with a fixed contact. In the contacting condition, the free ends of the contact springs touch each other. A first actuator portion of a relay armature serves to move the contact springs into the contacting position, and a second actuator portion serves to move the contact springs in the opposite direction to open the contact. The ratio of the spring lengths between the second actuator portion and the movable contact, divided by the thickness of this length of contact spring is smaller than the ratio of the spring lengths between the first actuator portion and the touching location of the two contact springs, divided by the thickness of this length of contact spring.

Abstract: A polarized reed relay comprises a bobbin with a coil wound thereon, two ferromagnetic contact reeds extending through an interior passage of the bobbin, a permanent magnet, and two pairs of pole shoes. Each contact reed is fixed at one end and has its other, free end cooperating with fixed contact portions formed by a pair of pole shoes. A relay is thus provided in which two double-throw contact systems electrically insulated from each other may be operated absolutely synchronously.

Abstract: A closure for a galvanic element, and particularly a cylindrical cell, is formed in substance of a cap-like or toroidal, resilient member, whose upstanding outer rim is segmented by slits into distinct flaps. These are therefore capable of acting resiliently in a radial direction and are capable of maintaining in the sealing region a steady sealing pressure between the cup and a plastic closure member. During closing of the cell through crimping, the flaps are supported from inside by a crimper support sleeve. In this way, the plastic of the closure body is plasticized during movement of the crimping tool toward the die.
