    摘要: Circuit arrangement intended for evaluating currents of 7 or 8 orders of magnitude, particularly in thermoluminescent dosemeter (TLD) evaluation equipment, which comprises a digital gate (12) with a feedback tag (13) and a charging capacitor (11) connected to the input of the digital gate (12). The other terminal of the charging capacitor (11) is connected to a stable voltage line, practically to ground. For varying the time constant the circuit arrangement has at least one control capacitor (14a to 14n) connected serially with corresponding electronic switches (15a to 15n). The other terminal of the control capacitors (14a to 14n) are connected to the input of the digital gate, through the input line (b) of the circuit arrangement. The switching inputs of the electronic switches are connected to control lines (v1 to vn), while other terminals of them are connected to stabilized voltage lines (e1 to en). For achieving decadic ranges of measurement the values of the control capacitors (14a to 14n) are either 9.10.sup.K multiples or 10.sup.K -1 multiples of the value of the charging capacitor (11). The electronic switches (15a to 15n) are switched off in their original position. The operating speed of the converter increases proportionally with the current I.sub.m to be measured and when it reaches its upper limit one of the switches (15a to 15n) will be switched on, thus the time constant increases and the operating speed decreases accordingly. If needed, a further or another control capacitor (14a to 14n) will be switched on.

    摘要: According to the process the sludge is homogenized and heated to 30.degree.-60.degree. C. temperature. The heated sludge is circulated under 2-4 bar overpressure, and its temperature is raised to about 130.degree.-150.degree. C. in 1-2 sec by conducting steam of 130.degree.-151.degree. C. and 2-4 bar pressure directly into the sludge, thus granulation is brought about in the sludge. The sludge of increased temperature--while its temperature and pressure maintained--is further circulated for about 60-300 sec. Then, the sludge is adiabatically expanded in 1-2 sec by reducing the pressure to about 0.01-0.02 bar. The expanded sludge is separated to water, fat containing water and solid impurity and wet solid phase containing protein.It is characteristic to the apparatus that it is provided with device for heating the sludge, and pipe (18) for passing on the heated sludge connected with the heating unit (5) where an expansion valve is built in. Pipe (22) joining the separating tank (7) is connected with the expansion valve (6). The apparatus is provided with separator for separation of the sludge leaving the tank (7) to water, fat and solid phase.

    摘要: A drier, especially for viscous materials, comprises a double-wall cylindrical vessel which is heated and to which the material to be dried is fed at one end with the dried material being removed at the opposite end. A drying gas inlet is connected to the drying chamber to pass the drying gas in counterflow or uniflow with the material and a shaft is rotatable along the axis of the chamber and carries adjustable disks with alternately inner and outer openings so that the material path through the vessel is deflected toward and away from the axis as the material passes successively through adjustable-length cells between these disks. All of the disks carry blades which scrape the material from the heated wall from the vessel and at least some of the disks carry rollers of predetermined spacing from this wall to adjust the particle size of the dried product.

    摘要: According to the invention, the grains of the hydrate slurry are separated by sedimentation where the dispersed bubbles of air are removed in course of the presizing, then a supplementary sizing is carried out. Preferably, a liquid free from hydrate grains is fed in to stream against the sinking grains. This liquid is advantageously the spent liquor of the hydrate filter. The apparatus according to the invention consists of a container with conical bottom, a feeding device, a slurry outlet stub and an overflow channel. The inlet stubs of the feeding device, however, are placed off-center and every stub is connected with a presizing equipment. This equipment is composed of a bundle of pipes and/or a pack of plates which are slop placed to geometrical axis: At the upper part of the presizing equipment there is a foam overflow apparatus. The bottom of each presizing equipment is connected with a common cone-frustum type deflector casing. The casing is concentric with the container. There is ring shape gap between the upper edge of the deflector casing and the cylinder jacket of the container. Under the deflector casing there is an upwards convex control cone. The control cone is vertically adjustable and concentric with the deflector casing.
