Abstract: This process concerns the disposal of fly dusts from waste incineration plants, in which the dusts are intensively mixed with other material, with the addition of water, and the mixture is then processed with compaction to give mouldings which are hardened in an autoclave at a saturated steam pressure of at least 1 bar. 
<??>In the case of fly dusts of low lime content, these fly dusts are mixed with cement or a mixture of cement and hydrated lime, with the addition of water, and fly dusts which contain hydrothermally convertible lime are mixed, with the addition of water, with cement or with a mixture of cement and materials of a type which bind lime in the hydrothermal process, such as, for example, ground quartz or fly dusts from bituminous coal-fired heat generator installations.

Abstract: A method for producing prostaglandins comprises converting unsaturated fatty acids contained in an alga belonging to genus  Gracilaria  or genus  Hypnea  into prostaglandins by the action of an enzyme present in the alga in water or a water-containing solvent so that the prostaglandins are released from the alga into the water or the water-containing solvent and then recovering the prostaglandins from the solvent; or comprises adding an unsaturated fatty acid to water or a water-containing solvent, converting the unsaturated fatty acid into prostaglandins by the action of the enzyme present in the alga belonging to genus  Gracilaria  or genus  Hypnea  in the solvent and then recovering prostaglandins from the solvent. The purification of prostaglandins can effectively be performed by a method which comprises contacting a solution of prostaglandins in water or a water-containing organic solvent with a non-polar porous synthetic resin having a specific surface area of not less than 350 m²/g and a fine pore volume of not less than 0.8 mℓ /g to thus adsorb the prostaglandins to the resin and then eluting the adsorbed prostaglandins with an organic solvent or a water-containing organic solvent for elution. The method makes it possible to provide desired prostaglandins in high yield and to produce prostaglandins in industrial scale.

Abstract: A double conversion system radio receiver having a high speed, precise and interference-free automatic channel selecting function includes an amplifying element (15) for amplifying an incoming radio frequency (RF) signal through an antenna (14), a first gain controlling (AGC) transistor (16) for controlling the output gain of the amplifying element, a second AGC transistor (19) differentially connected to the first AGC transistor for controlling the gain of the amplifying element, a tuning circuit (17) as an output load of the first AGC transistor and an impedance element (20) as an output load of the second AGC transistor. The tuning circuit outputs a narrow band RF signal having a frequency substantially tuned to a desired channel frequency. The impedance element generates a non-tuned wide band RF signal. At an automatic channel selection, the second AGC transistor is turned on, to generate a wide band RF signal from the impedance element for transmission to a subsequent stage. The wide band RF signal controls the gain of the second AGC transistor. After the channel selection by using the wide band RF signal, the first AGC transistor is turned on. At this time, the tuning frequency of the tuning circuit is set to the channel frequency selected in this   channel selection. The narrow band RF signal is generated from the tuning circuit for transmission to the subsequent stage in place of the wide band RF signal. The radio receiver further includes circuitry (33, 130, 137, 190) for fine-tuning the tuning frequency of the tuning circuit by using a narrow band RF signal after the channel selection by the wide band RF signal. The tuning circuit receives a tuning frequency control signal through a low pass filter (LP2). The radio receiver further includes a circuit (234;248) for switching the time constant of the low pass filter to a small value in a fine tuning and to a large value in a reception after the completion of the fine tuning.

Abstract: A computer graphics system is provided for manipulating the verti­ces contained within a group of possibly self intersecting, free space, over lapping polygons, into simple, convex polygons. A normal axis to the complex polygon is determined such that the surface of the polygon is viewed for resolving along this normal axis. The polygon surface is then bounded by a rectangle and subdivided into a group of slabs, or smaller rectangles, each rectangular slab being bounded by a pair of interior vertices of the complex polygon. An active edge table is used to store values corresponding to the edges crossing through the slabs, which are used to determine if these edges cross are another at any point within the slab. If a crossing point does exist, the slabs are divided at the crossing point into rectangular sub-slabs until it is determined that no edge intersects another edge within the sub-slabs, of the original slab being considered. At this point, the edges contained within the rectangular slabs can be viewed as simple polygons, or trape­zoids which can be filled by a conventional graphics adapter and then displayed.

Abstract: Skew angle of an image is determined based on determination of location of fiducial points on the image. Fiducial points may be located through a comparison of the scanning of a first line with scanning of a subsequent line. These fiducial points may be defined in terms of pixel color transitions located on a first scan line without a corresponding transition on the succeeding scan line. Skew angle may be determined from image data in uncompressed form or in compressed form. Where skew angle is determined from image data in compressed form, the two-dimensional CCITT facsimile recommendations may be used. In such cases, the locations of the fiducial points may be taken as the locations of the pass codes of the compressed image data. Specifically, pass codes indicating a pass of white pixels are used.

Abstract: In a demodulator circuit which is simple in construction, a PSK modulated signal is converted in frequency into a quasi-base band signal and is then subjected to complex separation. Partly since a phase angle sampled from a digital complex signal is supplied to a differential-detector circuit, and partly since the differential-detector circuit processes only the phase angle, the differential-detector circuit has a simple construction. As the detected phase difference between two successive symbol data, an error between a carrier wave contained in the modulated signal and a locally oscillated frequency on the receiving side is compensated and is outputted as a digital demodulated signal.

Abstract: A method and a twin-screw extruder for venting a thermoplastic, monomer-containing polymer melt are presented, in which the polymer melt and an entrainer are mixed with one another under a pressure, which prevents the entrainer from transforming from its liquid phase into its gaseous phase. The pressure necessary for this in the extruder can be achieved with the aid of a spectacles-shaped pressure diaphragm, which is connected non-positively by means of centering elements to the extruder housing and blocks off the processing space of the extruder in the downstream direction apart from a maximum of two through-openings for the extrudate.

Abstract: From an originating communication terminal (KE), a connection set-up of a service determined by a dialling procedure to a destination communication line (KAN) likewise determined by the dialling procedure is initiated with the aid of a communication switching system (KA) and it is checked whether a one-or multi-service communication device implementing the service concerned is available at that destination. In the event of a non-availability, an extended connection set-up procedure is used for determining whether a communication device (KE) implementing the same service from a predetermined group of services is available both at the destination communication line and at the originating communication line. If corresponding communication terminals (KE) are available, these are connected in a manner appropriate to the service if the corresponding communication terminals (KE) are not already occupied by existing communication relations in the integrated-services communication network. <IMAGE>
