Abstract: The invention relates to a circulating fluidized bed reactor comprising a centrifugal separator and a method for separating particles from gases. The centrifugal separator (12) is a vortex chamber composed of cooling planar plates or panels (32, 34, 36) (i.e. they are distinctly non-cylindrical), having at least one gas inlet (40), at least one gas outlet (52) and at least one outlet (46) for the separated particles. The cross section of the side walls (32, 34, 36) of the vortex chamber forms a distinctly non-circular gas space (31) (e.g. a polygonal cross section), have a circularity of greater than 1, e.g. > 1.1, and preferably > 1.15. One or more vertical, parallel gas vortices may be created in the vortex chamber, the gas introduced into vertical narrow slots. The outlets (46) for separated particles are not one the same symmetrical axes as the outlets for purified gas (52). Two adjacent vortices may be provided in a common rectangular chamber. The separator (12) is preferably in conjunction with a circulating fluidized bed reactor (10).

Abstract: PURPOSE: A detection and malfunction preventing circuit is provided to perform a stable inverter operation by varying the level of an interrupt signal after delaying for a predetermined time period upon detecting that a switch is pressed. CONSTITUTION: A signal delaying block(12) outputs function selecting signals(V1-V3) to a microcomputer(14) in response to the selection of switches(SW1-SW3) by a signal switching block(11). An interrupt block(13) maintains the level of an interrupt signal(INT) outputted to the microcomputer(14) in response to the logical operation of the outputs(V1-V3) of the signal delaying block(12), and has an AND gate(AN1), a clock generating block(15), inverters(IN1,IN2) and an OR gate(OR1). The AND gate(AN1) logically multiplies the outputs(V1-V3) from the signal delaying block(12). The clock generating block(15) outputs a high-potential signal(V5) in response to a low-potential output(V4) of the AND gate(AN1). The inverters(IN1,IN2) buffer the output(V4) of the AND gate(AN1). The OR gate(OR1) logically sums the output(V5) of the clock generating block(15) to output the interrupt signal(INT).

Abstract: The invention relates to a method and a circuit for measuring conductivity, in particular the conductivity of liquids in remote measuring systems. According to the invention, the method consists in obtaining a bipolar excitation voltage of a conductivity cell by the decrease of two unipolar excitation voltages, measuring the voltages in the circuit at the moments of maximal excitation voltages, comparing the two results, calculating the resistance/conductivity as a ratio of differences between the measured voltages multiplied by the value of a standard resistor () and a calibration constant, with the possibility of mediation or using the synchronous filtration; in case of liquid measuring, the method offers the possibility of diagnosing the interference with other measuring circuits, of separate evaluation of electrode clogging and of detecting the insufficient level of liquid within the conductivity cell. The circuit claimed by the invention comprises a resistor () with four terminals or a conductivity cell (), a standard resistor (), a digital-analogue convertor () with two channels (), an analogue-digital convertor () with five channels, a microcontroller () and a battery.
