  • Patent number: 11662194
    Abstract: A method for determining measurement points of an adapted measurement path for measuring a measurement object includes determining measurement points of an ideal measurement path. The method includes determining target measurement points of at least one guide path, which differs from the ideal measurement path. The method includes capturing actual measurement points along the at least one guide path using a coordinate measuring device. The method includes determining deviations between the target measurement points and the actual measurement points of the at least one guide path. The method includes determining the measurement points of the adapted measurement path by changing the measurement points of the ideal measurement path based on the deviations.

  • Publication number: 20200169158
    Abstract: The invention relates to a synchronously excited rotary machine with a superconductive rotor comprising a plurality of projecting first pole units of a magnetic material and a plurality of second pole units having superconductive coils wrapped around a core element of a magnetic material. Each second pole unit is positioned between two adjacent first pole units. The second pole units are spaced apart from aback iron and the first pole units via a plurality of thermally insulating support elements, wherein this spacing is evacuated so that it acts as magnetic air gap. An enclosed housing is provided on the back iron in which the first and second pole units are arranged, where-in the superconductive coils of the second pole units are in fluid communication with a cooling system. The first pole units and back iron are operated at an ambient temperature while the second pole units are operated at a cryogenic operating temperature.

  • Patent number: 9644143
    Abstract: Working material for absorption machines using ammonia (NH3) or methylamine (CH3NH2) or dimethylamine ((CH3)2NH) as the working agent and using water (H2O) as the solvent, to which a small amount of basic water glass is added, i.e., a certain mixture of water glass and bases, which does not contain any chromium salts as corrosion inhibitors.

  • Patent number: 8990089
    Abstract: A speech output is generated from a text input written in a first language and containing inclusions in a second language. Words in the native language are pronounced with a native pronunciation and words in the foreign language are pronounced with a proficient foreign pronunciation. Language dependent phoneme symbols generated for words of the second language are replaced with language dependent phoneme symbols of the first language, where said replacing includes the steps of assigning to each language dependent phoneme symbol of the second language a language independent target phoneme symbol, mapping to each one language independent target phoneme symbol a language independent substitute phoneme symbol assignable to a language dependent substitute phoneme symbol of the first language, substituting the language dependent phoneme symbols of the second language by the language dependent substitute phoneme symbols of the first language.

  • Patent number: 7979280
    Abstract: An input linguistic description is converted into a speech waveform by deriving at least one target unit sequence corresponding to the linguistic description, selecting from a waveform unit database for the target unit sequences a plurality of alternative unit sequences approximating the target unit sequences, concatenating the alternative unit sequences to alternative speech waveforms and presenting the alternative speech waveforms to an operating person and enabling the choice of one of the presented alternative speech waveforms. There are no iterative cycles of manual modification and automatic selection, which enables a fast way of working. The operator does not need knowledge of units, targets, and costs, but chooses from a set of given alternatives. The fine-tuning of TTS prompts therefore becomes accessible to non-experts.

  • Publication number: 20100029392
    Abstract: A torque transmission device for connecting, in a rotationally fixed manner, a shaft and a rotor of a rotating machine which has superconducting turns and which is coolable in order to create the superconducting state of these turns, having a torque-loadable hollow body which has a rotation axis and ends in a shaft connection at the shaft end and in a rotor connection at the rotor end, wherein, between the shaft connection and the rotor connection, the hollow body has a compensation area, which can expand in the axial direction, between the shaft connection and the rotor connection, in order to compensate for axial length changes resulting from temperature differences.

  • Patent number: 7531750
    Abstract: A power supply line for connecting a superconducting consumer system to a current delivery point, which is at a higher temperature than the consumer system, includes a carrier and a plurality of band-shaped, mechanically and electrically parallel high-temperature superconductors (HTSL). To achieve a high critical current density with simultaneously low heat-conducting capacity of the power supply line, the carrier includes at least one elongated plate that includes a sparingly (low) heat-conducting material, with a ratio of width to thickness of at least 3:1 and band-shaped HTSL that are arranged parallel adjacent to one another on the carrier. Each band-shaped HTSL also has a normally conducting current path.

  • Patent number: 5725793
    Abstract: The present invention proposes adding an alkaline solution or a mixture of two or more alkaline solutions to the agent system of absorption machines operating with ammonia or methylamine as the agent and water as the solvent. This addition of an alkaline solution or an alkaline solution mixture has a number of advantageous effects. These are, i.a.1. The dissolving respectively expelling heat of the agent is reduced, raising the output figure.2. The agent vapor generated is very pure. A dephlegmator is obviated.3. The alkaline solution makes steel surfaces inert when sealed from air and in a high vaccum, thereby obviating corrosion inhibitors.4. The viscosity of the solvent is reduced, decreasing pump operation.

  • Patent number: 4333894
    Abstract: A mass-transfer column consisting of one or more contact zones. The contact zones are exclusively provided with packings placed in prearranged locations. In the contact zones, optimal operating conditions for the packings are created over the entire height of the contact zones in order to achieve a minimal pressure loss at a concomitant high separating efficiency. This is done by implementing a suitable gradated adaptability of the packing to the vapor and liquid loads varying over the height of the contact zones.
