Abstract: A microprocessor-based controller is provided for generated heat in at various locations in an exhaust system of an engine by changing the heat generation technique utilized. In one case, some cylinder air-fuel ratios are modulated between stoichiometry and rich, while others are modulated between stoichiometry and lean. Another approach operates some cylinder lean, while others are modulated between a first rich, and a second, less rich, value. Further, compensation based on engine airflow is also provided. Finally, various methods are described for temperature control and for controlling modulation of air-fuel ratio.

Abstract: The invention relates to a new method and system for optimizing the efficiency of an automotive catalytic converter by adjusting the engine air/fuel ratio based on estimates of the actual amount of oxidants stored in the catalyst. An available oxidant storage capacity of the catalyst is determined by establishing an oxidant set point location, i.e., a location in the catalyst about which the system controls the oxidant storage. The oxidant set point is established based on the temperatures of the different potential set point locations and the levels of deterioration of the different potential set point locations, as well as the oxidant storage capacity of the emission control device system.

Abstract: A press forming machines includes displacement measuring means for measuring a displacement between a slide plate and a reference plate. Control means measures a positional displacement of each of the driving sources by using the displacement measuring means in each of a plurality of operating steps during the molding operation, detects a desired displacement position of the entire slide plate, extracts control data including a correction amount to maintain the entire slide plate at the desired displacement position, the correction amount corresponding to a change in load on each of the driving sources, stores the control data in the memory, supplies the control data to the driving sources, and separately drives the driving sources. Since an actual molding operation can be performed using control data generated in a trial molding operation, the cycle time of the actual molding can be shortened.

Abstract: A method for purifying sludge suspected of containing heavy, toxic and/or precious metals in order to extract them, the sludge being suspended in an aqueous solution and together forming a mass to be treated. FeCl3 is mixed with the mass, until an acidic pH of the solution is obtained. (CO2H)2 and NH4Cl are then mixed with the mass until metal pro-chelates are formed. Mixed alkali sulfides are then mixed with the mass until a solution with a very basic pH is obtained, to form colloidal complex iron chelates, which trap the metals. The solution is neutralized by adding an acid, until alkaline-ferrous sulfides and hydroxides containing the metals are precipitated. The mass is then centrifuged to form from the mass a liquid phase and a solid phase, the solid phase containing the alkaline-ferrous sulfides.
