Abstract: The present invention relates to a method of making paper from bleached or alkaline treated pulp by dewatering pulp containing bleached or alkaline treated vegetable fibers from wood or non-wood species. It was found that such bleached or alkaline treated pulps contain a substantial amount of harmful pectins. By incorporating pectinase in the bleached or alkaline treated pulp such harmful pectins in the aqueous phase of the pulp are degraded and thus rendered harmless to papermaking processes.

Abstract: In order to accelerate an asynchronous machine (5), its stator is connected via a switch (S2) to a secondary winding (W3) of a converter transformer (T1), while the rotor is connected via a cycloconverter (3, 4), in a V-circuit, to secondary windings (W2, W3) of the converter transformer (T1). The secondary winding (W3) has a reduced AC voltage (U12) on the converter side, in the region of 5% - 10% of the AC voltage (U1) of the AC power supply (1). The asynchronous machine (5) is coupled on the rotor side to a single-phase synchronous machine (6). Such rotating frequency converters are used for transmitting electrical power in the range from 8MW - 90MW from a national grid (1) at 50 Hz or 60 Hz to a single-phase railway network (2) at 16<2>/3 Hz or 25 Hz, and vice versa. The single-phase synchronous machine (6) is not energised during acceleration, so that undesirable harmonic torques at double the stator frequency do not occur and a longer life of mechanical components, such as pole connections, fans etc., is achieved. <IMAGE>

Abstract: Water, esp. condensate, from a compost plant, is oxygenated, especially by aeration. It is then filtered by reverse osmosis. The raw condensate is first modified, to facilitate biological clarification. The content of the water, determining oxygen demand, is measured; the quantity of material to be separated out is determined. Raw condensate is inoculated, to set the metabolic functions of the micro-organisms. The predetermined material to be separated, is filtered out. Metabolism in the bio-reactor is oxygen-controlled, esp. by air input, and/or the nutrient input, and/or pH control, and/or temperature control. Filter performance, esp. membrane filter performance, is controlled by pressure and/or throughput. Also claimed are: The use of a bio-reactor, a composting process, and composting equipment. <IMAGE>

Date Jul. 25, 1996A receiver for spectrum analysis includes at least one mixer in which a radio frequency input signal to be measured is mixed with an oscillator frequency generated by a voltage-controlled oscillator. In a detector, the level of an input signal to be measured is detected, after the signal has been transferred onto a lower frequency. The use of a logarithmic amplifier may be avoided by directing the detected signal to a decision means, which, in response to a change in the level of the detected input signal, provides a control voltage proportional to the magnitude and the direction of the change. The voltage commands an adjustable attenuator to attenuate the signal to be measured so that the level of the detected input signal substantially remains constant. The attenuation of the attenuator measured in decibels is linearly dependent on the control voltage, so that the values of the control signal directly represent the amplitude values.
