Abstract: This invention is directed to a method of making an olefin product from an oxygenate feedstock and a method of protecting catalytic activity of a silicoaluminophosphate molecular sieve. The methods comprise providing a silicoaluminophosphate molecular sieve having catalytic sites within the molecular sieve; shielding the catalytic sites to protect from loss of catalytic activity; and contacting the protected sieve in its activated state with an oxygenate feedstock under conditions effective to produce an olefin product before undesirable loss of catalytic activity. Undesirable loss in catalytic activity occurs when activated molecular sieve contacting the oxygenate feedstock has a methanol uptake index of at least 0.15.

Abstract: The invention concerns a method for continuous smelting of solid metal products in a reactor comprising a smelting zone and a metallurgical processing zone, which consists in continuously heating the solid metal products in the smelting zone, gradually transferring said smelted products into the metallurgical process zone, refining the smelted products in the metallurgical process zone in an oxidising slag medium, separating the metallurgical process zone slag from the smelting zone slag, transforming the oxidising slag in the metallurgical process zone into a reducing slag, desulphurizing the smelted products in the metallurgical processing zone in a reducing slag medium and casting the smelted metal.

Abstract: In order to implement a method of graduating the dissipation of an alternating electrical power signal, provision is made to place the position (Reg3) of a period of the alternating signal in correspondence with the binary inverse (Reg4) of a digitized set-point parameter. It is shown that, in this way, the periods of dissipation are ideally distributed among the periods of non-dissipation. This has the principal effect of reducing the effects of blinking which are particularly undesirable when the rise time of the phenomenon to be controlled is short as regards the period of the alternating electrical signal.
