    摘要: A method providing control power for an electricity network in which at least one energy store supplies energy to the electricity network and/or takes up energy from the electricity network dependent on a frequency deviation from a desired frequency of the electricity network, a deadband being prescribed around the desired frequency. The frequency deviation from the network frequency is measured with greater accuracy than a width of the deadband and a bandwidth within the deadband is chosen dependent on a charging state of the energy store, with control power being provided outside the bandwidth. A device carrying out the method includes at least one energy store and a control system controlling control power of the energy store in an open-loop or closed-loop manner, the energy store being connected to an electricity network such that energy can be fed into the electricity network and can be removed from the electricity network.

    摘要: There are described thermoelectric elements that are manufactured by using a porous matrix or a porous substrate. The matrix consists of an electrically insulating material having sufficient thermal and chemical resistance as well as the lowest possible thermal conductivity, and is provided in predetermined regions with different thermoelectric materials, so that continuous conductors are formed in the matrix. These are electrically connected to one another to form thermocouples, which in turn are electrically interconnected with one another to form the thermoelectric element.

    摘要: A method for epoxidation of olefins with 2 to 6 C atoms, especially propene, with hydrogen peroxide in the gas phase at a temperature below 250° C. The reaction is carried out by bringing a gas mixture containing the olefin, hydrogen peroxide and water into contact with the catalyst from the series of compounds of an element of the 4th to the 6th subgroup of the periodic table or of arsenic or selenium and molecular sieves in the absence of a liquid phase. Titanium-containing molecular sleeves are preferred catalysts.
