Abstract: The pulp is passed through a high-pressure delignification reactor run (R1-R3) and then depressurized and heated with steam before being supplied to a reactor system (R4) in a low-pressure run where the dwell time is greater than that in the high-pressure run. - A continuous process for the alkaline oxygen gas delignification of cellulose pulp which has been cooked and optionally washed (W1) after cooking and which is stored in a substantially atmospheric storage tower (ST) or pulp tank, comprises the use of a reactor system with multiple oxygen gas reactors. The pulp being delignified has a consistency of 8-18 % and a kappa value of at least 15 (more than 20). During delignification, alkali (NaOHMAIN) is added to the pulp to provide a starting pH of more than 9 and 5-50 kg oxygen per tonne pulp is added at a point before the first oxygen gas reactor in the system. The total dwell time for the pulp in the system is more than 45 minutes. The pulp is pressurized to a starting pressure of more than 15 bar during the initial addition of chemicals and initial mixing in required for delignification, then the pulp is supplied to multiple mixing locations (M1-M3), the pressure in the final location being at least 13 bar. The dwell time in this first high-pressure run is at least 3-10 minutes. The pulp is then depressurized to less than 10-12 bar, heated with steam in order to increase its temperature by at least 5 deg. C and then supplied to a reactor system in a low-pressure run where the dwell time is greater than that in the high-pressure run.

Abstract: An optical lens (4) is situated in a closed vessel (1-3) containing an atmosphere including a doping substance. The vessel (1) has a window (5) for a laser beam (13) from a laser unit (10) situated outside the vessel. By mutual displacement of the laser unit (10) and lens (4) the laser beam (13) is caused, to a controlled, varied extent, to affect the lens surface with heat such that the doping substance diffuses into it in response to the heat supply of the laser beam (13) to the object. The gaseous doping substance is selected to affect the refractive index of the surface of the lens (4) irradiated by the laser beam (13).

Abstract: Subsynchronous resonance in a network is controlled by monitoring the frequency of an electrical generating system 10 and controlling the resonance by phase-firing thyristors to insert compensating inductance L into the network. The frequency is monitored by measuring half-periods and comparing with a standard frequency, using pulse counting to establish an error signal. The network voltage may also be stabilised by controlling the firing of the thyristors. <IMAGE>

Abstract: The invention relates to a method for recovering the valuable metal content of a mix of contaminated copper raw materials, of which materials at least one is sulphide bearing, and which contain one or more impurities forming the group arsenic, antimony, bismuth, mercury, tin, chlorine and other halogens. The invention is characterized by adjusting the halogen content of the mix so that it is substantially at least stoichiometric in relation to remaining impurities in the group, whereafter the mix is charged to a furnace in which melting can take place and in which the mix is heated to at least 500°C, but beneath the melting points of respective ingredients of the mix, while maintaining good contact with hot gas therewith to expel substantially all of the aforementioned impurities present. The mix is then heated to completely smelt the ingredients present, to form a slag and a copper matte, which latter contains the valuable metal content, whereafter this valuable metal content is recovered with the aid of a suitable, conventional method.At least one of the copper raw materials present in the mix comprises suitably a halogen-bearing valuable-metal containing product, for example chlorine-bearing ash or slag.

Abstract: A method of removing nitrogen and phosphorus from waste water by using an activated sludge including aerobic bacteria is disclosed. The waste water is fed continuously and gradually into a treatment basin in which the sludge is contained so that a mixed liquor consisting of the waste water and the sludge is formed therein. A cycle consisting of an agitating step and an aerating step is repeated at least two times and each cycle is finished within two hours, with the ratio of the agitating time to the aerating time being between one to one and to one. In the agitating step, the mixed liquor presents an anoxic condition and a succeeding anaerobic condition. Denitrification occurs in the anoxic condition and the aerobic bacteria release phosphorus in the anaerobic condition. During the aerating step, nitrification is caused while the bacteria excessively ingest phosphorus from the mixed liquor.
