4512802 PROCESS FOR THE DECARBURIZATION OF MOLTEN METAL
Large power transformers such as used at electrical generating plants utilize oil for cooling with the heat removed by air cooled radiators. Several air cooled radiators are removed from the transformers and the oil circulated through plate heat exchangers which provide a heat transfer path to a fluid cooling medium such as water. Flow transducers and electrical temperature sensors may be used to monitor the flow rates of the oil and water, and the temperature of the oil and water in various parts of the system. These parameters are controlled to maximize the transfer of waste heat from the transformer to the water. The heated water is then utilized to perform useful work. For example, in a power plant having package boilers, the boiler makeup water is preheated with the transformer waste heat thereby reducing the energy requirements of the system.

A computer implemented process for optimizing the decarburization of a predetermined mass of molten metal by controlling the amount of coolants, the charging time of coolants, the dilution ratio of injected oxygen to inert gas, the changing time of the dilution ratio and the amount of injected gases which includes: considering from a standpoint of kinetic theory the reaction in AOD vessel is composed of following three reactions, i.e., the reaction in the vicinity of tuyeres, the reaction taking place in the ascending process of bubbles and the reaction in the interface between metal and slag; establishing the mathematical Model I; establishing the mathematical Model II calculated capably in short time and kinetically from the result using the mathematical Model I, and from the vessel factor calculated from the data of an actual operation; and further utilizing the mathematical Model II as a controlling program in an actual operation.

4513571 METHOD OF SUPERCHARGING INTERNAL COMBUSTION ENGINES USING EXHAUST TURBOCHARGERS WITH VARIABLE EXHAUST GAS SWALLOWING CAPACITY Ernst Jenny, Andreas Mayer, Peter Moser, Baden, Switzerland assigned to BBC Brown Boveri & Company Limited A method for supercharging internal combustion engines with turbochargers wherein the engine is operated in the lowest load region as a naturally aspirated engine, and the waste gate, the inlet section of the turbine and all other exhaust gas ducts present are fully open. When this load range is exceeded, the flow area of the turbine inlet is reduced to its minimum operational value and subsequently, with a further increase in load, is increased again to its maximum value at full load. The engine operated according to this method has a varioturbocharger whose turbine inlet flow area is controlled by a throttle slide as a function of the fuel injection quantity and the boost pressure by means of an adjustment device and a control pressure modulator.
4513810 LOW GRAVITY EXOTHERMIC HEATING]COOLING APPARATUS Richard M Poorman assigned to The United States of America as represented by the Administrator of the National Aeronautics and Space Administration A low gravity exothermic heating/cooling apparatus is disclosed for processing materials in space which includes an insulated casing (10) and a sample support (16), (18) carried within the casing which supports a sample container (14). An exothermic heat source (A) includes a plurality of segments (20) of exothermic material stacked one upon another to produce a desired temperature profile when ignited. The ex-
othermic material segments are constructed in the form of an annular element having a recess opening (22) which defines an open central core (23) throughout the vertical axis of the stacked exothermic material (A). The sample container (14) is arranged within the core (23) of the stacked exothermic heating material. Igniters (24) are spaced vertically along the axis of the heating material to ignite the exothermic material at spaced points to provide total rapid burn and release of heat. To rapidly cool and quench the heat, a source (30) of liquid carbon dioxide is provided which is conveyed through a conduit (32) and a metering orifice (36) into a distribution manifold (34) where the carbon dioxide is gasified and dispersed around the exothermic heating material and the sample container via tubes (38) for rapidly cooling the material sample.
