Title: Process for generating an SO3-containing gas for exhaust gas purification in the electrostatic precipitator
Inventor: LEUSSLER WILHELM ING GRAD
IPC: B01D51/10
Filed: 1981-06-15
Abstract: In the process, sulphur is burnt with air in a furnace for generating an SO2-rich combustion gas. The combustion gas is passed through a converter for catalytic conversion in the presence of oxygen to give SO3. The SO3-containing gas is admixed to a steam-containing exhaust gas before the purification in an electrostatic precipitator. The sulphur is fed to the furnace in liquid form via a metering device, the combustion air is conducted through an air heater upstream of the furnace. The temperature of the combustion air is controlled in dependence on the sulphur metering; an additional regulation of the combustion air temperature is carried out via measurement of the gas temperature at the intake or exit of the converter. The sulphur metering can be regulated via measurement of the dust content in the clean gas leaving the electrostatic precipitator or else via measurement of the exhaust gas flowrate upstream or downstream of the electrostatic precipitator.

Abstract: An arrangement for closed-loop control of the air/fuel ratio of an internal combustion engine has an emission control system with a catalytic three-way convertor for closed-loop control of the air/fuel ratio as a function of the operation of the engine. A throttle sensor for identifying an operation with the throttle valve of the engine wide open and a device for feeding a predetermined voltage are provided. A feedback control circuit controls the air/fuel ratio to the stochiometric air/fuel ratio for the normal operating state. A storage device stores a value corresponding to the output control signal of the feedback control circuit. A first switching device is provided which is actuated by the output signal of the throttle sensor in order to connect the output of the device to feed the predetermined voltage to the input of the feedback control circuit if a deceleration is identified and in order to switch off the input of the storage device in order to preserve its stored contents. A second switching device is provided which is actuated by the output signal of the throttle sensor in order to deactivate the feedback control circuit as a feedback controller, as a result of which the air/fuel ratio is controlled by the output signal of the device to feed the predetermined voltage. After the operation with the throttle valve wide open the feedback control circuit restarts with the stored contents of the storage device. <IMAGE>

Title: Circuit arrangement for the regulated supply of a load
Inventor: BERGK GUENTHER
IPC: H02M3/156
Filed: 1982-08-30
Abstract: The invention relates to a circuit arrangement for the regulated supply of a load. The circuit arrangement which is used both for charging a battery and for the power supply of a motor has a flyback converter with a transformer, a controllable transistor being connected to the primary winding of the transformer. Since the battery is connected via the series circuit of two resistors and the collector-emitter junction of the controllable transistor, the inductance and transistor tolerances have virtually no effect on the charging current. For function indication, a light-emitting diode can optionally be connected in parallel with the secondary winding of the transformer, in series with a diode and a bias resistor, or a light-emitting diode can be connected in parallel with the base-emitter junction of the controllable semiconductor switch, in the case of the latter possibility, the light-emitting diode being used at the same time as a limiting diode for the negative base-emitter voltage during the period when the controllable semiconductor switch is switched off. <IMAGE>
