Abstract: The water treatment system (12) includes a flooded fixed-bed reactor (22) for the microbiological water treatment, in particular the elimination of nitrogen. Below the fixed-bed reactor (22) there is located a first aeration unit (26) through which air is passed in and water is conveyed through the fixed-bed reactor (22) in a rising flow by the air lift pump effect. Downstream of the fixed-bed reactor (22) there is arranged a degassification and coagulation zone (72), a sedimentation zone (74) and a second aeration unit (52) through which air or, preferably, oxygen, is passed in, and the water is enriched with oxygen. The oxygen concentration of the water flowing back into the fish tank (10) is in this manner decoupled from that of the microbiological water treatment from the control engineering point of view. <IMAGE>

Abstract: A method and apparatus are provided for adaptively equalizing data signals in a communications receiver. An unequalized data signal is demodulated. The demodulated data signal is filtered in an adaptive equalizer (60) that initially updates adaptive filter coefficients using error signals derived from a first algorithm. A carrier lock signal is generated (62, 78) when a phase error of a filtered signal output from the adaptive equalizer reaches a threshold value. The adaptive filter coefficients are updated (74) using error signals derived from a second algorithm instead of the first algorithm in response to the carrier lock signal (72). The first algorithm is a self-recovering equalization algorithm such as the Constant Modulus Algorithm. The second algorithm can be a decision directed algorithm. Carrier phase is recovered without the use of a phase rotator or phase de-rotator, by locating the adaptive equalizer inside of the carrier recovery loop (56). The invention is particularly adapted for use in the recovery of multilevel amplitude modulated data, such as QAM data. <IMAGE>

Abstract: A lead-in conductor for sealing into the glass envelopes of lamps, electrode tubes and similar components is composed of a molybdenum alloy containing 0.01 - 5 % by weight of one or more oxides of the lanthanides, the rest being molybdenum. It is particularly advantageous if the molybdenum alloy contain 0.1 - 1 % by weight of lanthanum oxide. The particular suitability of this alloy for lead-in conductors stems from the surprisingly good welding properties of the alloy in relation to itself, to pure molybdenum and to other molybdenum alloys.

Abstract: A method of and apparatus for packaging a beverage in a container 1 having a primary chamber and a relatively smaller secondary chamber which communicates with the primary chamber by way of a restricted orifice has the exterior of the container maintained at atmospheric pressure. The container such as a can 1 to be charged with beer is engaged within a filling head block 24 through nozzles 35 from which beer 9 is to flow into the can 1 from a bowl 8. Prior to filling the can 1 is pressurised through the head 24 with nitrogen gas to greater than atmospheric pressure and subsequently evacuated to atmospheric pressure by control of valves 32, 33. Such pressurisation and evacuation may be repeated sequentially to dilute the atmospheric oxygen content within the primary and secondary chambers of the can 1 where the oxygen has negligible effect on the beer which is to be sold in the can. A gas exchange conduit 40 extends between the bowl headspace 12 and the can 1. Conduit 40 has a port 41 of a gas control valve 55 which port 41 is closable by movement of lever 60. A beer flow valve 37/46 controls flow of beer 9 from the bowl through nozzles 35. During pressurisation of the can 1 with nitrogen gas the lever 60 is adjusted to maintain closed the port 41 of the gas flow valve and the beer flow valve 37/46 to ensure that high pressure gas in the can 1 cannot flow by way of the gas exchange conduit 40 into the bowl headspace 12 and again flow through the nozzles 35 into the beer 9 in the bowl 8. <IMAGE>

Abstract: An ion engine comprising means for the generation of primary plasma by discharge in a gas wherein said discharge is obtained by means of the simultaneous use of a magnetic conditioning and confinement field and an electromagnetic field, the latter being at a frequency such that the cyclotron resonance effect of the electrons in the gas can be exploited. The engine comprises means (5, 7) of generating a static magnetic field and means (9, 11) of generating and applying an electromagnetic field at cyclotron frequency. By using the cyclotron resonance effect, it is possible to improve the processes of plasma generation and the processes of ion beam extraction by means of the use of an optimized system of grids made of refractory material. These processes are optimized to match the differences in the operating conditions acting on the intensity of the magnetic field. <IMAGE>

Abstract: A method and a device for producing hydrochloric acid by contacting a hydrochloric-acid-containing gas with an aqueous washing liquid are disclosed. A chloride-forming substance is added to the washing liquid, so that the hydrochloric acid in the gas not only is bound by the chloride-forming substance as a chloride salt, but also is absorbed by the washing liquid as 'free' hydrochloric acid. Optionally, the washing liquid is then concentrated by stripping of water. Subsequently, sulphuric acid is added to the washing liquid to drive off hydrochloric acid from the chloride salt. Finally, hydrochloric acid is distilled from the washing liquid. The device includes a scrubber (1) having inlets (2, 10, 11, 12) and outlets (5, 13), a distillation unit (25) having inlets (27, 24) and an outlet (29), and optionally an evaporation unit (14) having an inlet (16) communicating with the scrubber outlet (13), and an outlet (24) communicating with the distillation-unit inlet.

Abstract: A drive for a phacoemulsification probe (13) includes a drive circuit (15) for supplying electrical power to the probe (13), circuitry (29) for sensing the electrical power supplied by the drive circuit (15) to the probe (13) and for supplying electrical signals indicative of the magnitude of the electrical power supplied. A manually operable input device (21) provides a signal indicative of the transducer power level desired by the user of the probe (13). A control circuit is responsive to the signal indicative of the desired transducer power level and to the signals indicative of the magnitude of the supplied electrical power for providing control signals to the drive circuit (15) to control the power applied in an efficient manner. The drive circuit (15) includes a totem-pole switch (31), responsive to at least one of the control signals, to apply power in a square-wave waveform, and a switching regulator (27) for supplying a supply voltage to the totem-pole switch (31). The totem-pole switch (31) has circuitry associated therewith which is responsive to one of the control signals to initially vary the frequency of the square-wave waveform. The regulator (27) is responsive to a second control signal (A) from the control circuit to vary the voltage supplied by the regulator (27) to the totem-pole switch (31) to control the amplitude of the square-wave waveform. The switching nature of this system substantially minimizes the power consumption of the drive circuit (15) as compared with conventional techniques. <IMAGE>
