摘要:
A heat settable, coating system of carboxyl-functional polyester resins, polyfunctional epoxy compounds and/or &bgr;-hydroxy alkyl amides, as well as further customary additives, if required. The coating system contains at least one linear carboxyl-functional polyester resin of up to 10 mol-part of isophthalic acid and at least 90 mol-parts of at least a further dicarboxylic acid from the group of aromatic dicarboxylic acids with 8 to 16 C-atoms, aliphatic dicarboxylic acids with 6 to 22 C-atoms and cycloaliphatic dicarboxylic acids with 8 to 16 C-atoms, and at least 90 mol-parts of at least one branched aliphatic diol with 4 to 12 C-atoms, and up to 50 mol-parts of at least one linear aliphatic diol with 2 to 22 C-atoms and/or at least one cycloaliphatic diol with 6 to 16 C-atoms as the binder resin. Also a process for producing thermosetting coating systems of carboxyl-functional polyester resins, wherein binder resin, at least one cross-linking agent from the group of polyfunctional epoxy compounds and &bgr;-hydroxy alkyl amides and, if required, further customary additives are mixed into the melt at 90 to 130° C., extruded, removed, granulated, comminuted and screened to a size of less than 100 &mgr;m. Finally, uses of the thermosetting coating system and of a protective layer produced from this coating system.
摘要:

摘要:
A device to control a gas-fired appliance as a function of the composition of a gaseous fuel. The device includes a thermal conductivity sensor emitting a measurement signal dependent upon the thermal conductivity of the gaseous fuel. An analyzing unit receives the measurement signal and uses it to develop a control signal dependent upon the composition of the gaseous fuel. A control unit receives the control signal and uses it to control the operating parameters of the gas-fired appliance, in the case of a gas engine particularly the parameters of air/fuel ratio, output and angle of advance. The analyzing unit may include an input interface into which data on the type of gaseous fuel components may be entered, which are used for the generation of the control signal. Preferably the control signal is proportional to the available methane number of the gaseous fuel, whereby the operating parameters of the gas engine are controlled so that the methane number required is adjusted to the methane number available. This leads in particular to an improvement in the knocking behavior of the gas engine.
