Title: Method and control device for the series and parallel coupling of elements of an electrochemical generator supplying a motor
IPC: B60L15/04
Filed: 1973-08-10
Abstract: The method modifies the coupling of the elements of electrochemical generator by commutating means enabling, according to the conditions of operation, the coupling of at least two groups, for example identical, of said elements either in parallel, or in series. The commutating means are actuated, as a function of at least one of the parameters of the power demanded at the motor, in such a way that whatever the rotary speed of the motor, parallel coupling is effected in all cases where the power demanded can be supplied by this coupling. A signal of the power demanded is established as a function of at least one parameter of the power actually delivered, and of at least one threshold signal corresponding to the maximum value which the abovesaid parameter can take, all things being otherwise equal, in parallel coupling. The signal of the power demanded and the threshold signal are compared and the passage from series coupling to parallel coupling is actuated when the signal of the power demanded is less than the threshold signal. The parameter selected may be the average voltage (UM) of the induced coil of the motor or an image of this voltage.

Title: Process and apparatus for drying and preheating coking coal by means of flue gas
IPC: C10B39/02
Filed: 1978-08-01
Abstract: Flue gas discharged from a recuperator or regenerator of a coke oven battery has the steam thereof removed by means of a direct or indirect cooling and condensation operation. After the steam is removed from the flue gas it is then passed through a coke dry cooling plant in direct contact with hot coke therein to form dry cooled coke while simultaneously increasing the temperature of the flue gas. The flue gas is then passed through a coal preheating plant to directly contact and dry and preheat moist coking coal contained therein. The entire system is open, such that a given quantity of the flue gas passes only once through the system. When the temperature of the flue gas as received from a coke oven battery is extremely high, then the flue gas may be subjected to a partial cooling operation prior to the cooling and condensation operation. Further, a portion of the heat of the flue gas, after the discharge thereof from the coke dry cooling plant and prior to the introduction thereof into the coal preheating plant, may be used to generate steam and/or electricity.
Patent ES-472730-A1 (ES)
Title: Process for producing stainless steels
IPC: C21C5/00
Filed: 1978-08-21
Abstract: Disclosed herein is an improvement in a process for preparing a stainless steel of low carbon content from a steel melt containing chromium or chromium nickel of higher carbon content where the process is carried out in a converter having at least one blast nozzle below the molten steel bath level and at least one blast lance above the bath level wherein oxygen is supplied to the steel melt through the blast lance and inert gas is supplied through the blast nozzle during a first refining phase, and in a succeeding refining phase oxygen is combined with inert gas and introduced through the blast nozzles to the steel melt, the proportion of the oxygen being reduced in relationship to the proportion of inert gas with decreasing carbon content of the steel melt. The improvement of the invention permits a decrease in the amount of inert gas supplied during the first refining phase while not significantly increasing the refining time. The improvement resides in employing as at least one of the nozzles one having an axially movable bar within the passageway of the nozzle, the bar being extended through the nozzle passageway to the mouth of the nozzle during the first refining phase and being withdrawn from the mouth of the nozzle during the successive refining phase. By such an expedient, the amount of gas passing through the nozzle in the first refining phase is reduced, and the amount of gas passing through the nozzle in the successive refining phase is increased.
