Title: Rotary kilns and methods of treating charges in them
IPC: C21B13/08
Filed: 1971-07-06
Abstract: 1338795 Reducing metal oxides INTERNATIONAL NICKEL CO OF CANADA Ltd 6 July 1971 [8 July 1970] 31733/71 Heading C7D [Also in Division F4] A method of heating charges, which are subjected to an oxidizing or reducing atmosphere flowing through a conventional rotary film, comprises the introduction into the kiln of gases having no detrimental effect on the atmosphere at the point of introduction and at least 2400‹F. produced by the complete reaction of atomized liquid hydrocarbon and a gas containing uncombined oxygen in a side burner 49 (see Division F4] shown in greater detail in Fig.2, which comprises a refractory tube with a sharp change in its cross-section and sufficiently thick walls to maintain the interior surface incandescent in use. The method is particularly suitable for the reduction of heavy metal oxides (i.e. oxides of iron, nickel, copper, cobalt, and mixtures thereof) and for the selective reduction of nickel with only small amounts of iron from nickelferous oxides ores. The charge is introduced from a chute 38 and passed down the kiln against a flow of hot gas from a main burner 34 at the other end, first through a pre-heating zone and then through a reducing zone in which the side burner discharges its gas through a lateral outlet 66 in counter-current to the gas flow from the main burner. The side burner is fed with insufficient oxygen to ensure that its combustion products are reducing. A second similar side burner mounted in the pre-heating zone may be fed with excess oxygen which then reacts with the uncombusted fuel from the first side burner flowing from the reducing zone. The invention may also be applied to oxidizing treatments as well. A mixture of hydrogen and carbon monoxide may be added to the kiln at suitable points to provide the desired atmosphere.

Abstract: A device for the translation of electrical into visual information includes a body of silicon having one or more first regions of one conductivity type material on the surface of a second region of the opposite conductivity type material, and means for applying a reverse bias breakdown voltage between the first region or regions and the second region so that a selected length of the junction or junctions between the regions is caused to emit light.  In the device shown in Fig. 1 an ohmic contact 3 is located on the shallow P-type region 2 and ohmic contacts 4 on the N-type region 1.  The negative pole of <PICT:0941252/C3/1> <PICT:0941252/C3/2> a battery is connected to contact 3 and the positive pole to a selected one of the contacts 4. The device is made by depositing boric oxide through a mask on the surface of a polished slice of N-type silicon 1 which is then heated at 1250 DEG  C. for 2 hours in an oxygen atmosphere to cause the diffusion of boron into the silicon to produce the P-type region 2. Excess boric oxide is removed by washing for a few minutes in 40% hydrofluoric acid followed by deionized water.  The contacts 3 and 4 are made simultaneously by vacuum evaporation through a mask.  In the device shown in Fig. 2 there is an N-type region 5 and four P-type regions 6-9, an ohmic contact 10 making contact with the N-type region 5 and ohmic contacts 11-14 with the P-type regions 6-9. The device is made by diffusing boron into silicon as above, the P-type regions 6-9 being made of increasing depth by successive diffusions for different periods of time to produce different breakdown voltage junctions between each of the regions 6-9 and the region 5.  In operation the contact 10 is connected to the positive terminal of the voltage supply and all the contacts 11-14 to the negative terminal and the voltage is gradually increased from zero to produce successive breakdowns of the PN junctions with the emission of light.
