Abstract: Die Erfindung betrifft ein Verfahren zur Langzeitentfernung von chlorierten Biphenylen (PCB) aus Transformatorisolierflüssigkeiten beim Ersatz von PCB-Ölen durch andere Isolierflüssigkeiten, insbesondere Silikonöle. Der Vorteil des erfindungsgemäßen Verfahrens liegt darin, daß PCB-Verunreinigungen aus Transformatorisolierflüssigkeiten kontinuierlich oder quasi kontinuierlich entfernt werden können, wobei nur geringe Mengen eines Adsorberharzes eingesetzt werden müssen und eine Ansammlung von chlorierten Biphenylen in der Transformatorisolierflüssigkeit vermieden wird.  Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß die Isolierflüssigkeit kontinuierlich durch ein Adsorberharz für PCB-Öl gefördert wird, das Adsorberharz nach seiner Beladung mit PCB-Öl durch Waschen mit einem Lösungsmittel für PCB-Öle hiervon befreit wird und das mit Lösungsmittel gewaschene Adsorberharz vor dem erneuten Einsatz zur Adsorption von PCB-Öl durch Spülen mit Gas von Lösungsmittel befreit wird.

Abstract: In a motor vehicle with an automatic gearbox, the selector device is supplemented by a gear-change element which can likewise be actuated at will and by means of which, given the existence of the criteria of a significant driving state (for example engine overrun), an electronic control unit is caused to input via the gear-change device, an associated significant gearbox state for a single operation (e.g. lowest forward gear), which state influences the driving state in a predetermined manner (increase in the engine braking effect), the special operation being cancelled again by actuation of the accelerator pedal.

Abstract: There is provided a food container in which a container body 1 is provided with a glaze layer 4, a heating region 5 is provided with a metal-like layer 7 which heats up by induction in an electromagnetic alternating field, and the metal-like layer 7 is covered by a ceramic protective layer 8. It is here desirable if the bonding of the metal-like layer with the food container is durable without impairing the properties of the layer in the electromagnetic alternating field despite the firing temperature of the ceramic protective layer. This is achieved by the metal-like layer being formed of a layer 7 applied to the glaze layer of a fired-on silver composition whose properties are resistant to firing temperatures of from 600 DEG C to 920 DEG C, and by the ceramic protective layer 8 being formed of a flux material fired on at from 600 DEG C to 920 DEG C. Despite the firing temperatures used and although the metal is formed of silver, this layer has, durably and pronounced, the desired heating (warming) action in the electromagnetic alternating field. <IMAGE>

Abstract: The invention relates to a method for generating steam using a waste incinerator, wherein steam (A) is formed from water in a heat exchanger by heating same with flue gases from a waste incinerator and is then fed to a steam drum, conducting flue gases in a heat exchanger along bundles of pipes through which the steam (A) from the steam drum is fed in order to create steam (B) at a temperature of at least 450 DEG C and at a pressure of at least 70 bars, and wherein the steam (B) is fed to the first turbine stage. After leaving one stage of the turbine, the steam is reheated in a heat exchanger with the aid of steam (A') which comes from the steam drum so as to create steam (D) that is fed to at least one successive turbine stage. By feeding the steam to be reheated from the steam drum, there is an extra degree of freedom in the dimensioning of the boiler. It is possible to realise a net efficiency of more than 30% in combination with a second and third economiser. <IMAGE>

Abstract: An oscillator (1) is trimmed by a digital-to-analog converter (5) that receives a digital trimming signal in response to difference between a desired frequency and a reference frequency. The oscillator (1) generates a frequency that is M times higher than the desired frequency. A divider (2) divides the oscillator frequency by M to provide the desired frequency. A splitter (4) splits the digital trimming signal into a digital coarse trimming signal, and a digital fine trimming signal. The converter (5) converts the digital coarse trimming signal into an analog coarse trimming signal. A comparator (6) receives the digital fine trimming signal, compares it with a counter signal received from a counter (7) repeatedly counting M periods of the oscillator output signal, and generates an output signal until the value of the digital fine trimming signal and the counter signal are equal. The converter (5) receives said comparator output signal and converts it into an analog fine trimming signal that is added to said analog coarse trimming signal to control the oscillator (1).
