  • 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: 8930082
    Abstract: A steering method for an industrial truck includes manually steering at least one steerable wheel with a steering transducer. The at least one steerable wheel is hydraulically connected or mechanically connected with the steering transducer. An angular position of the at least one steerable wheel is detected. At least one additional steerable wheel is motor-steered as a function of the detected angular position.

  • Publication number: 20150001007
    Abstract: An industrial truck includes a chassis comprising a plurality of wheels, and wheel suspensions. Each wheel suspension is mounted on the chassis around two axes so as to be tiltable. At least two wheels of the plurality of wheels are each mounted on the chassis via a respective wheel suspension.

  • Publication number: 20140091261
    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: 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.
