Abstract: A heat dissipating element contains graphite and a microencapsulated phase-change material (PCM). The heat dissipating element is provided with a Li-ion battery for a car, truck, or pedelec to control the temperature of the battery. The heat dissipating element allows the capacitance of the Li-ion battery to remain at a higher level and more energy to be available for heating the passenger compartment.

Abstract: A latent heat storage device is formed with a carrier substrate formed of expanded graphite material. Phase change material is infiltrated in the graphite material. A thin graphite sheet provides for the functional heat conductivity into and out of the carrier substrate. After the phase change material (PCM) is infiltrated in the carrier substrate, a density of the infiltrated carrier substrate exceeds its starting density by a ratio of at least 3:1 or 4:1 or more. The volume dimensions of the infiltrated the carrier substrate remain substantially unchanged. In the alternative, the latent heat storage device may also have a PCM coating layer on a thin carrier substrate, wherein the phase change material is interspersed in a carrier matrix forming the PCM coating layer. The composite device may be very thin.

Abstract: A heat dissipater has a graphite-containing flat material provided for adjacent positioning against one or more battery cells, as well as an electrical energy storage device with at least one battery cell and a heat dissipater for removing heat from the battery cell. The heat dissipater has a graphite-containing flat material and is disposed on at least one external face of the battery cell. Accordingly, the graphite-containing flat material contains graphite expandate.

Abstract: Cathodes for aluminum electrolysis cells are formed of cathode blocks and current collector bars attached to those blocks. The cathode slots receiving the collector bar are lined with expanded graphite lining thus providing longer useful lifetime of such cathodes and increased cell productivity. The expanded graphite provides a good electrical and thermal conductivity especially with its plane layer.

Abstract: An anode assembly for aluminum electrolysis cells includes carbon anodes with stubholes and an anode hanger having stubs, in which the anodes are fixed to the anode hanger by cast iron and the stubholes are fully or partially lined with an expanded graphite lining. The anode assembly provides a reduced voltage drop across an interface between the cast iron and the carbon anode and thus increases cell productivity significantly. Mechanical stresses in the stubhole area are reduced. A collar formed from the lining prevents spilling of cast iron over the anode surface and a protective shot plug or a protective collar optionally prevent direct contact of a hot electrolyte bath with the stub and the cast iron. A method of manufacturing anode assemblies and an aluminum electrolysis cell, are also provided.

Abstract: A method for applying a thin coating to a flat side (front side) and edge surfaces of a two-dimensional formation of graphite foil, includes applying the coating material to the flat side (front side) to be coated by electrostatic powder spraying followed by a sintering cycle or melting cycle. During the spraying, the two-dimensional formation is electrically contacted on a limited area virtually in the middle of its rear side, facing away from the spraying direction, on a limited area at a distance of at least 5 mm from the edges. A method for heat dissipation in electronic equipment, is also provided.

Abstract: A process for the preparation of polyisocyanates which contain one or more biuret groups, by reacting a) an aliphatic or cycloaliphatic isocyanate containing two or more isocyanate groups (isocyanate a) with b) a tertiary alcohol or a mixture of water and a tertiary alcohol (biuretizing agent b) at from 100 to 250° C.

Abstract: Bodies made of expanded graphite are impregnated with low-viscosity, solvent-free, storage-stable, polymerizing resins from the group of isocyanates and their co-reactants and/or epoxy resins up to resin contents of 50% by weight. A primary product is made of expanded graphite with an open pore system, with a particularly preferred range of bulk densities of from 0.5 to 1.3 g/cm3 and with an ash value of not more than 4% by weight. Such bodies can also contain a proportion of additives. Sealing elements, components in fuel cells and heat-conducting elements are formed of the impregnated, shaped and rapidly curable graphite bodies. A process for producing such bodies is also provided.

Abstract: A method or apparatus for controlling a braking system in a vehicle, the vehicle including an inside front wheel and outside front wheel, whereby a determination is made of whether a drifting and/or an oversteering condition exists; and, if so, a predetermined braking pressure is applied to the outside front wheel.

Abstract: A lane change by a motor vehicle is detected in a first variant, such that a lateral-acceleration variable representing the lateral acceleration of the vehicle and/or a yaw variable representing the yaw velocity is ascertained; the change, as a function of time, of the lateral-acceleration variable and/or of the yaw variable is formed; and a lane change is detected when the change as a function of time exceeds a specifiable threshold value. A second variant provides that speed variables are determined which represent the rotations of at least two wheels; a velocity variable is ascertained representing the longitudinal vehicle velocity; the difference is determined between the speed variable of the fastest rear wheel and the velocity variable; and a curve and/or a lane change is detected when a specifiably large difference exists for a time duration of specifiable length.

Abstract: A reducing agent or an additive that releases an agent is often added to an exhaust gas from engines in order to chemically convert constituents, in particular nitrogen oxides, in the exhaust gas. To achieve intimate mixing of the exhaust gas with the reducing agent or additive over a short section of the gas duct, at least one mixer and at least one nozzle for introducing the additive into the exhaust gas are structurally and functionally combined with one another.
