Abstract: A multi-mode electronic wind turbine control system establishes a reference blade angle B R  for a two-bladed, horizontal axis, variable pitch wind turbine rotor, the blade angle being regulated by a hydraulic pitch change mechanism (38). The rotor (10), via appropriate shafts and a gearbox (20), is coupled to a synchronous generator (24) to produce electrical energy which is fed to a power utility grid. The control system (36) provides closed loop pitch control for rotor acceleration rate during start-up, for rotor deceleration rate during shutdown, for speed control when the synchronous generator is off-line, and for power control when the synchronous generator is on-line. A single control integrator is used for all closed loop operating modes, with a rate limiter circuit in front of the control integrator to prevent integrator ovenravel. The integrator has maximum and minimum blade angle stops, the minimum stop being variable as a function of rotor speed and wind speed. When on-line, power control is provided by a unique shaft torque control using proportional plus integral plus derivative controls in combination

Abstract: An oxydative biological purification process for waste water, comprising passing the waste water through an oxida- ion space containing aerobic activated sludge at such a rate, hat the residence time in the oxidation space is between 0.3 and 20 h and a space load of COD of 4-50 kg / m 3  day and of aitrogen of at most 2.5 kg/m 3  is achieved, maintaining in the pxidation space a pH between 5 and 9 and substantially completely separating the purified waste water flowing out of the oxidation space from aerobic activated sludge and recycling he separated sludge into the oxidation space, the aerobic activated sludge being attached to a carrier and being sepa- ated from the waste water leaving the oxidation space by settling. 
     According to a preferred embodiment the settling tank is placed at a higher level than the oxidation space in order to avoid special provisions (e.g. recycle lines with pumps) and to savethe floor space. 
     Preferably the aerobic activated sludge is attached to sand having an average granularsize between 0.1 and 2 mm. 
     The purification is preferably carried out at a temperature of 10-60°C. 
     The process enables a reliable waste water purification, even when the COD of the waste water is strongly varying and even when varying amounts of waste water are available, and supervision by skilled persons is practically not necessary.

Abstract: In producing synthetic hydrocarbon oils by polymerization of olefins using aliminum halide as the catalyst, organic halides are produced. These are corrosive to metal equipment and are poisonous to certain hydrogenation catalysts. This invention eliminates the problems caused by such organic halides by reacting them with an aromatic hydrocarbon in a system also containing the polyolefins thus forming an alkylation product with both reactants prior to removal of the aluminum chloride catalyst.

Abstract: Text editing and subsequent reformatting of a document is performed in two separate stages run as two parallel processes with different priorities. The editing of text is performed as a high priority process directly on a selected portion of the document previously copied under control of edit/format control logic (7) from a document store (5) into a refresh buffer (3). The editing process takes each keystroke as it is received by control logic (7) from keyboard (8) and enters it into buffer (3). The contents of the buffer (3) are directly mapped onto a display screen (2) so that the updated portion of the document is immediately seen by the operator. Should insufficient space be available in buffer (3) to accommodate an edited line of text, space is made available by controlled wordspill of text from the line into auxiliary storage prior to execution of the editing operation. Reformatting of the edited text is conducted as a low priority process taking one line of the document at a time and any words in auxiliary store for inclusion in that line. Reformatting is interrupted by the occurrence of keystroke signals requiring further editing of the text.
