    摘要: In a process for ultrasonic testing of elongated, prism-shaped sections (22) with at least one planar outer surface (54) extending along the longitudinal axis (26) of the section, with the objective of detecting material defects or verifying geometric data, the section (22) to be tested is exposed to ultrasonic beams from several ultrasonic probes (28 to 34) installed in a probe carrier (44). The section (22) is moved along its longitudinal axis (26) in relation to the probe carrier (44). The latter is installed in the rotor (20) of a rotary testing machine which rotates around the longitudinal axis (26) of the section (22). The probes (28 to 34) are installed in the probe carrier (44) so that each can be displaced individually, either transversely or, preferably, at right angles to the longitudinal axis (26) if the section (22) and the direction of the probes and/or so that their angular position can be adjusted individually by swivelling them around a swivel axis ( 58) running parallel to the longitudinal axis (26) of the section (22). The individual probes (28 to 34) are adjusted so that the central beams (46) emitted by each probe (28 to 34 ) impinge upon the planar outer surface (54) adjacent to one another, thus forming adjacent scanning zones in the volume of the section (22) to be tested. The probes (28 to 34) are triggered individually by an arrangement for determining the angle between the rotor (20) and the section (22); testing is only performed when the angle between the central beam (46 and the planar outer surface (54) lies within a predetermined range.

    摘要: A preheating moist fine material, such as pit coal and lignate, peat, wood, oil shale, or even ores or limestone for cement production, and an apparatus for carrying out the method are disclosed. Moist fine material is mixed above a heater with predried and preheated material until the mixture is made fluid. The fluid mixture slides down between and piles up to a level above the heater. A part of the predried and preheated fine material is removed from below the heater in an amount corresponding to another part thereof and is conveyed to above the heater with the moist fine material.

    摘要: A process for releasing ammonia which is bound in coal water using a pre-desulfurization plant having ammonia and hydrogen sulfide scrubbers through which crude coking plant gas is passed comprises circulating the crude coke oven gases through the hydrogen sulfide scrubber and the ammonia scrubber in succession, directing the coal water first through the ammonia scrubber while the crude coking plant gases are being also circulated therethrough after passing it first through the hydrogen sulfide scrubber. An alkali solution is also circulated through the ammonia scrubber to enrich the solution with acid components and to liberate ammonia bound in the coal water directing the coal water which has been enriched from the ammonia scrubber into the hydrogen sulfide scrubber. The process is characterized by the fact that the alkali solution which has first served for the hydrogen sulfide scrubber is added to the ammonia hydrogen sulfide scrubber. 80 to 90% of the total alkali solution is charged to the hydrogen sulfide after-washery and then on the hydrogen sulfide pre-washery and the rest is charged to an ammonia expulsion apparatus.

An emptying channel is located under the lower lateral edge of the tank.
