Abstract: A method for starting a combustion device, in particular after a first ignition failure, in particular for starting a gas burner under unknown basic conditions, wherein a characteristic diagram of a start air ratio depending on the burner temperature known from empirical analysis is stored for the combustion device in a memory, wherein a calibration of the starting process is performed, wherein the ratio of opening of the gas valve (w) to air volume mL necessary for ignition is iteratively determined by variation of the gas and/or air volume; and in case of ignition, the combustion device is started and the applicable air ratio (?)IGNITION is stored.

Abstract: A method is proposed for regulating a firing device taking into account the temperature and/or the burner load, in particular with a gas burner, comprising the regulation of the temperature (Tactual) produced by the firing device using a characteristic which shows a value range corresponding to a desired temperature (Tdesired) dependent upon a first parameter (mL,VL) corresponding to the burner load (Q), wherein when representing the characteristic, a second parameter, preferably the air ration (?), defined as the ratio of the actually supplied quantity of air to the quantity of air theoretically required for optimal stoichiometric combustion, is constant.

Abstract: The temperature generated by a firing apparatus, particularly a gas burner, depends on the mixing ratio between the quantity of air and the quantity of gas fed to the firing apparatus, characterized by the excess air coefficient ?, at a predefined burner load (air mass flow rate) in such a way that the temperature generated by the firing apparatus reaches a maximum when ?=1. According to the inventive method for adjusting the excess air coefficient, said maximum temperature Tmax is determined, whereupon the desired setpoint value ?hy of the excess air coefficient is adjusted and the associated setpoint temperature Tsoll is measured. A characteristic curve which represents the correlation between the respective air mass flow rates and the setpoint temperatures at the setpoint value ?hy of the excess air coefficient and allows combustion to be regulated to an optimal hygienic state can be determined from said determined correlation between the setpoint temperatures Tsoll at different predefined burner loads.

Abstract: An inking unit for a rotary printing machine includes an ink fountain, a pivotable ink fountain holder in which the ink fountain is mounted, an ink ductor, and a pivotable ink ductor holder in which the ink ductor is mounted. The ink ductor holder and the ink fountain holder are connected by an operating cylinder so that ductor and the ink fountain can be pivoted jointly to a first position in which ink flows out of the ductor without flowing out of the fountain, and so that the ductor can be pivoted away from the first position to a second position while the ink fountain remains in the first position, thereby creating a gap between the ductor and the ink fountain.

Abstract: The present invention pertains to an adjustable canister purge valve (9) and method having a first connection (10) for an intake pipe (11) of an engine and a second connection (14) for an activated carbon filter (5). The first (10) and second connection (14) are interconnected by means of a first adjustable valve (16) enabling the flow of a regenerating mixture (8) of air and fuel-vapor. A second valve having a larger flow cross-section (22) is connected in parallel with the first valve (16) and allows a large regeneration air flow, even with a low suction vacuum, and thus improved purge.
