20100330365 | STRAND-LIKE MATERIAL COMPOSITE WITH CNT YARNS AND METHOD FOR THE MANUFACTURE THEREOF - A strand-like material is formed of CNT yarns that are embedded in a metal matrix. The embedding in a common matrix has the advantage in that the material composite exhibits an improved electrical conductivity. This lies in the ability for electrons to switch from the CNT to the matrix and back again. The strand-like material composite is therefore suitable for use as an electrical conductor. Further proposed is a method for producing the strand-like material composite. | 12-30-2010 |
20110031125 | Method for the electrochemical coating of a substrate by brush plating and device for carrying out said method - A method for the electrochemical coating of a substrate uses brush plating. This is to take place with an electrolyte in that particles are dispersed, which are embedded into the developing layer. It is proposed to add the particles to the carrier for the electrolyte by way of a separate conduit system. The electrolyte is added by way of a conduit system. In this way it is achieved that an agglomeration of the particles in the electrolyte can be prevented because only a short time passes between when the particles are fed and the layer is formed. A device for electrochemical coating has two conduit systems provided for this purpose. | 02-10-2011 |
20120180783 | CENTRAL TUBE FOR A LINEAR CONCENTRATING SOLAR THERMAL POWER PLANT, HAVING AN ABSORBER LAYER, AND METHOD FOR APPLYING SAID ABSORBER LAYER - A central tube for linear concentrating solar thermal power plants, has an absorber layer. The absorber layer is generated by cold gas sputtering, wherein suitable method parameters can in particular generate an increased surface roughness by means of pores in the surface region of the absorber layer. An absorber layer can thus be advantageously produced, having a quadratic roughness of no more than 1 μm, measured in a close range of no more than 50 μm diameter, and preferably being made of a corrosion-proof hard alloy comprising tungsten carbide, in particular WC—CoCr, WC—Co, WC—FeCo, WC—FeC, WC—FeNi, WC—Ni or WC—NiCr. | 07-19-2012 |
20140123772 | FORCE TRANSDUCER FORMING A CAPACITIVE LOAD CELL - A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading. | 05-08-2014 |
20140338329 | INSTALLATION FOR STORING THERMAL ENERGY - An installation for storing thermal energy which can be obtained, for example, at times of overcapacities, from regenerative energy and then be stored is provided. The energy stored in a heat accumulator, a cold accumulator and in an additional heat accumulator can be, when needed, reconverted into electrical energy by circuits via a generator (G) while using a compressor and a turbine. The working gas is humidified by a humidification column, ideally until saturation, whereby, advantageously, a greater mass flow can be obtained at a lower volume flow. For this reason, more economical components can be used while simultaneously a high yield of the installation is achieved. | 11-20-2014 |
20140352295 | INSTALLATION FOR STORING THERMAL ENERGY AND METHOD FOR THE OPERATION THEREOF - An installation for storing thermal energy is provided, comprising a heat accumulator and a cold accumulator. A method for charging and discharging said thermal accumulators is also provided. Using the installation, excess electrical energy can be utilized for converting mechanical energy from a compressor and a turbine into thermal energy, which is available in the heat accumulator and the cold accumulator for a subsequent generation of electrical energy. A temporary heat store is discharged during the charging of the heat accumulator and the cold accumulator, preheating the working gas for the compressor. When the heat accumulator and the cold accumulator are discharged via the turbine and the compressor for the purpose of generating electrical energy, the temporary store can be recharged so that the heat stored therein can be made available for a subsequent charging process of the heat accumulator and the cold accumulator. | 12-04-2014 |
20150059342 | SYSTEM FOR STORING AND OUTPUTTING THERMAL ENERGY AND METHOD FOR OPERATING SAID SYSTEM - A system for storing and outputting thermal energy and a method for operating the system are provided. The system operates according to the Brayton cycle, wherein a heat accumulator is charged by a compressor and a cold accumulator is charged by turbines. The cycle is reversed for discharging. In addition, the cold accumulator supplies a cooling circuit, which provides the cooling for a superconducting generator by a cooling unit. A favorable generator weight can thereby be advantageously achieved in particular for wind turbines, because the generators are limited regarding the weight thereof due to being housed in the nacelle of the wind power plant. Thus, advantageously higher power can be converted in the wind power plant. | 03-05-2015 |

By means of the heat accumulator, it is possible to convert overcapacities of wind turbines, for example, into a charging circuit as heat in the accumulator by a compressor. If necessary, electricity can be stored into the network by a turbine and a generator, wherein the heat accumulator is discharged. The charging circuit and the discharging circuit are operated by a Rankine cycle, wherein for example river water is available as a reservoir for heat exchangers in order to cause evaporation of the working medium in the charging circuit and condensation of the working medium in the discharging circuit. | 03-19-2015 |

The heat accumulator and the cold accumulator can be charged, for example, with excess energy from the electric network by a motor. Excess energy reserves of alternative energy resources, for example, can thus be stored. | 05-21-2015 |

The discharging takes place by means of a steam turbine which has a high-pressure part and a low-pressure part. In order to provide heat to both turbine parts, the heat accumulator is divided into a part-accumulator for the high-pressure part and a part-accumulator for the low-pressure part. Furthermore, a system is provided in which the heat accumulator is divided into two part-accumulators. By operating a turbine with the high-pressure part and low-pressure part, the efficiency and yield of heat from the heat accumulator can be advantageously increased.
