The invention also provides a method for producing the composite part comprising treating the thermoplastic material with a solution of a SBR or SBS rubber in an organic solvent or with an aqueous latex of the rubber, if necessary, completely or partially removing the organic solvent or water, if necessary, treating the dried mass with a powdered SBR rubber which may contain a filler, and covulcanizing with a rubber containing carbon-carbon double bonds.

Abstract: The subject of the present invention consists of a method and an apparatus for measurement of the fluorescence relaxation period of the radiation of a fluorescent substance whose fluorescence relaxation period is a function of at least one physical parameter. The fluorescence radiation is fed back to the output radiation in a regulating circuit, whose regulating parameter is a parameter for the physical parameter. This is accomplished by advancing the fluorescence radiation to a photoelectric receiver whose output signals are supplied to a voltage controlled oscillator following phase-sensitive rectification and integration. The fluorescence radiation is alternately phase-sensitively rectified only during the relaxation phase. The total durations of the different rectification periods in the two directions are identical. The alternatingly rectified signals are integrated.

Abstract: A cyclone arrangement for cleaning gas from a gas generator for gasifying coal which is exhausted at high pressures. The invention proposes that the cyclone arrangement for the cleaning of crude gas includes at least two cyclones connected in parallel on their input sides, which cyclones can be turned on and off individually. Thereby a dry cleaning of the crude gas can be performed with only a slight temperature loss. The quantity of gas corresponding to the optimum cleaning efficiency can be adjusted to the quantity of gas either discharged from the gas generator or actually required for the pressurization of the steam generator by adjusting the number of cyclones put into operation, without the need for the inclusion of buffer capacities. The gas generator comprises a pressurized fixed bed reactor.

Abstract: A coal gasifier has a fluidized bed reactor. The gasifier has a series of cyclones connected to an outlet of the gasifier to clean the gas generated by the fluidized bed reactor to isolate particulate matter. The cyclones are turned on and off individually to compensate for the variations in the gas output of the fluidized bed reactor.

Abstract: An apparatus is proposed which serves to control the quantity of exhaust gas recirculated from the exhaust gas system of an internal combustion engine to its intake side. The apparatus includes a pneumatic final control element having a diaphragm defining a work chamber, the diaphragm arranged to actuate a valve closing member of an exhaust gas recirculation (EGR) valve. Via a control pressure line, a flow line leading to the atmosphere and a connecting line leading to the intake tube downstream of a throttle valve are connected to the work chamber. A check valve opening toward the intake tube, a reservoir and a throttle restriction are disposed in the connecting line. A bypass line having a bypass valve bypasses the throttle restriction.

Abstract: A process for the gasification of carbonaceous agglomerates in a reactor at a pressure of the range of 5 to 150 bar. The agglomerates are fed into said reactor from a storage zone located above the reactor and form a fixed bed in the reactor, in which they slowly descend when gasified. At least two gasification agents selected from the group consisting of oxygen, air, steam and carbon dioxide are introduced into said reactor through the bottom and rise through said fixed bed. Solid ash or liquid slag is discharged below said fixed bed and a steam-containing product gas is tapped from the reactor above said fixed bed. In order to minimize or prevent the condensation of steam on the agglomerates in the storage zone, the invention provides for a controlled atmosphere almost entirely free of oxygen and steam which is introduced into the storage zone at a pressure approximately equal to the pressure of the product gas.
