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: An electrochemical secondary element with a non-aqueous electrolyte, whose charge/discharge mechanism is predicated upon the reversible intercalation of active Li+ ions in electrode materials having an open skeletal structure. The positive electrode is essentially a lithium-manganese spinel of the type Li.sub.q M.sub.x Mn.sub.y O.sub.z which, in addition to satisfying the expressions 0<x<0.6 and 1.4<y<2.0, can also contain up to 30% of other metals such as Co, in addition to Mn. The negative electrode is based on a carbon product obtained by pyrolysis from organic compounds, and serves as the recipient substance for the Li+ ions. By limiting the Li concentration in the spinel lattice to a range in which the numerical values of the variable q lie between 0 and 1.3, a lithium-poor manganese spinel is obtained.

Abstract: This choke device is characterized in that a starting pump 49 for supplying the fuel in a fuel tank 25 by suction to a starting nozzle port 41, is driven by a fuel motor 53. Starting of the engine is executed by the use of a starting motor or a recoil starter, by supplying the fuel in the fuel tank 25 to the starting nozzle port 41 through sucking of the fuel with the starting fuel pump 49 which is turned by the fuel motor 53, thereby facilitating the ignition by augmenting the concentration of the mixed gas.

Abstract: To change a rotational direction of a working apparatus such as a nut runner, rotational positions of a crankshaft at the highest voltages of primary currents in normal and reverse rotating operations are symmetrically arranged in relation to a rotational position corresponding the top dead center of a piston, and the rotational positions of the highest voltages are set before the rotational position corresponding the top dead center of the piston. In rotating the engine either in the normal or the reverse direction, the voltage of a primary current of an electromotive coil 97 reaches the highest value at a predetermined rotational position before the top dead center of the piston 7. An ignition unit 177 detects that a predetermined voltage close to the highest voltage is attained or that a predetermined voltage drop from the highest voltage has occurred, to short-circuit the primary current and generate a high-voltage current in a secondary circuit.

Abstract: In a lithium secondary cell of the intercalation type, with a positive electrode which includes a lithiated transition metal oxide Li.sub.x M.sub.y O.sub.2, wherein 0.5.ltoreq.x/y.ltoreq.1.0 and M is a metal from Groups VIIb and VIIIb (preferably Co, Ni, Mn), and with a negative electrode formed of a carbon product with disordered crystalline structure produced from organic materials by delayed coking, both electrodes are uncharged in the initial assembly state, but the negative electrode is doped with lithium through prelithiation in an amount which is irreversibly consumed in the formation of ion conductive surface layers. This permits a loss-free deintercalation of any subsequently introduced lithium so that the cell exhibits, from its inception, a largely stable capacity during cyclic charge/discharge operation.

Abstract: Device permitting localization of the emergence point of ventricular tachycardias in cardiological medicine, characterized, in comparison with traditional cardiac mapping, by: a precision of the same order, its speed of use, its low cost and the further possibility of localizing the macro-re-entry pathway (around aneurysms, for example).In distinction to traditional mapping, this device dispenses with the construction of a map of isochrones (14).The principle of the device according to the invention is based on localization of the propagation of the myocardial cell depolarization, or of the muscle contraction of the heart (15) which results directly therefrom. This localization is carried out in stages (17) over the length of its pathway (13) from an arbitrary point (16) on the heart chosen by the operator, retracing this pathway as far as its source (12'), which is referred to as the emergence point.
