  • Publication number: 20200247533
    Abstract: A method for detecting damages to a rotor of an aircraft, where the aircraft comprises actuators for active vibration reduction, may comprising one or more of the following steps: determining actuator variables in a reference flight of the aircraft; plotting the actuator variables of respective data range tiles determined in the reference flight of the aircraft in first coordinates of a coordinate system, wherein the coordinate system contains numerous data range tiles; obtaining the number of actuator variables in the reference flight of the aircraft that are located in each data range tile; eliminating the data range tiles that have a number of actuator variables lying below a limit value for this in the reference flight of the aircraft, by means of which a reference flight signature is created; and determining actuator variables for a flight-specific signature.

  • Publication number: 20200138240
    Abstract: A transportable device for heating food is provided. The device includes a container for receiving the food, a heating compartment, which is thermally coupled to the container by way of a heat-conducting wall, calcium oxide being present in the heating compartment, and a liquid supply unit including a liquid reservoir chamber, in which a water-containing liquid is present, wherein the liquid supply unit is designed so that, based on actuation on the part of a user, the water-containing liquid is brought into contact with the calcium oxide, or the substance mixture including calcium oxide. The water-containing liquid has an elevated dynamic viscosity, in comparison with water, of between 2 and 30000 mPas, and preferably between 50 and 1000 mPas or, alternatively, the liquid supply unit comprises a water retention agent. In both alternatives, the reaction between calcium oxide and water is damped and delayed.

  • Publication number: 20200056304
    Abstract: The invention relates to carbon fibers which are produced from CO2 based on different process chains. Amongst these, there are ways to produce, from natural base materials such as algal biomass, carbon fibre base materials such as PAN from CO2, but there are also purely artificial ways to produce, by means of Fischer-Tropsch synthesis, via which carbon fibre precursors are also produced from CO2. Auxiliary products such as biodiesel and nutrients, which can generate an additional benefit, are produced according to said method.

  • Patent number: 9851125
    Abstract: A transportable device for heating foodstuffs includes a container for receiving the foodstuff as well as a closed-off heating chamber which adjoins the container and is thermally coupled thereto while simultaneously being hermetically separated therefrom via a shared, thermally-conductive wall. The heating chamber includes a first chamber and a second chamber that are separated by a water vapor-permeable wall. In the first chamber is a substance or a substance mixture which, when a liquid, preferably water, is supplied, generates heat in an exothermic chemical reaction with water vapor being formed. In the second chamber, a zeolite is located which can adsorb the water entering from the first chamber via said water vapor-permeable wall, generating heat. A transportable heating element which can be used in the device contains a hermetically-sealed heating chamber that adjoins a thermally-dissipating outer wall.

  • Patent number: 9555878
    Abstract: The present disclosure provides a rotor blade control device for a helicopter. The rotor blade control device may include a swash plate disk with a non-rotating component coupled to the helicopter. At least three actuators may be arranged around a rotor shaft axis of the helicopter, and a coupling element may be located between each actuator and the non-rotating component.

  • Patent number: 6328235
    Abstract: The invention relates to a process and an apparatus for decomposing articles, especially contaminated articles, by means of a decomposition device. To make it possible to the use an easily manipulated decomposition device while avoiding bulky devices, and at the same time to enable in-situ decomposition, in the tightest possible space, in a way that suits packing needs, it is proposed that the decomposition device execute an oscillating motion such that as a function of the progress and/or duration of the decomposition of the article, a varying resultant of the direction of decomposition force introduced by the decomposition device is established.
