Abstract: The unit serves to convert an electrical control signal (I) received at the input of the unit into a pneumatic signal (P). This is emitted at the output of the unit and its value should be proportional to the value of the control signal (I). The unit comprises a tongue-shaped piezoelectric element (6) which is loaded with a voltage dependent on the control signal, so that the element (6) carries out a lateral bending movement which varies with the voltage. The unit also comprises a pneumatic line (1) with a chamber (1a) which is supplied with compressed air via a throttle (4) and from which the compressed air is conducted through a nozzle (3) located near to one side of the piezoelectric element (6) so that the air pressure in the chamber is regulated by the piezoelectric element (6) as a function of the said voltage; and an outlet line (5) leading from the chamber for transmitting the regulated air pressure to the control system as the said pneumatic signal (P). To make the pneumatic signal (P) to the control system accurately follow the electrical control signal (1), a pressure transducer (7) is connected to the outlet line (5), being designed to produce an electrical signal (T) which corresponds to the regulated air pressure, and which is fed back via a feed-back circuit to the input of the unit. Furthermore, the input has a circuit (9, 11) which receives both the electrical control signal (1) and the fed-back electrical signal (T). The circuit has a device (9) for forming a difference signal by comparing the two signals (I, T) and a device (11) for integrating the difference signal and thereafter producing from the integrated difference signal the voltage with which the piezoelectric element (6) is loaded.

Abstract: An apparatus for rectification of fermented solutions comprises acolumn (1) with topping and rectifying sections (5, 6), trays (9) intended for the liquid/gas exchange and spaced along the height of the column (1), a heat exchanger (14), connected through a system of pipes (16, 16) to the rectifying section (6) of the column (1) and sockets (4, 12, 13), correspondingly, for inletting the raw material and the heating steam to the column (1) and for outletting the bottom product. The cross-section area of the upper part (8) of the rectifying section (6) of the column (1), which is located by 2 to 8 trays (9) above the socket (4) for inletting the raw material equals to 0.25 to 0.64 of the cross-section area of the resting part of the column (1) whereas the total capacity of the trays (9) of the upper part (8) of the rectifying section (6) equals to 0.04 to 0.40 of the total capacity of the rest of the trays (9) of the column (1). A method of automatic control of the apparatus for retification of fermented solutions provides for regulation of the feeding of the raw material and the heating steam to the column (1) and of the bleeding of the spirit condensate, and furhter provides for correction of the above parameters depending on losses of the spirit together with the bottom product. The losses of the spirit together with the bottom product are determined through the content of the spirit in the vapour phase of the bottom product taken from the 2<nd> to 5<th> tray (9) of the topping section (5) of the column (1). The group of inventions can be most successfully used in installations of indirect type operation or in autonomous apparatus containing one column for rectification of fermented solutions.

Abstract: The invention relates to a method for regenerating an adsorbent with respect to organic substances adsorbed therein. These organic substances are expelled with warm gas by desorption and are destroyed by combustion. The invention is characterized in that the warm gas is an air-combustion-gas mixture; in that the gaseous mixture exiting from the adsorbent is combusted, when applicable after adding an auxiliairy fuel, at a combustion temperature of 750-850  DEG C; in that the resultant combustion gas is first cooled by adding air and then by heat exchange with the gas mixture exiting from the adsorbent. At least one part-flow of the thus cooled mixture of air and combustion gas is then brought into contact with the adsorbent to form said gaseous mixture, subsequent to adding an amount of air needed to achieve a predetermined temperature at each moment in time.

Date Oct. 27, 1994A strainer for removing particles from a horizontal flow of effluent comprises a plurality of parallel fixed bars adapted to extend angularly downwardly into the flow of effluent and a set of parallel displaceable bars interdigited with the fixed bars. The displaceable bars are interconnected and connected to a drive mechanism to cause the displaceable bars to move in a circuitous path such that the displaceable bars move upwardly relative to the fixed bars to remove material engaged thereon and are thence thereafter lowered, whereby the material is lifted upwardly along the fixed bars. The displaceable bars are supported at their lower ends to the drive mechanism by a flexible connection apparatus so that the path of movement of the displaceable bars is unconstrained to minimize stress on the strainer should debris become lodged beneath the lower end of the displaceable bars.
