Abstract: In directional radio and satellite radio, energy lines which have as small a loss as possible are required between apparatuses and antennas. Waveguides are used for this purpose in the higher frequency bands (GHz band). In order to reduce their attenuation at frequencies above 10 GHz it is possible to operate them in a low attenuation manner in overmoded operation and to use a mode filter to attenuate higher wave-mode types. In order to achieve an energy transmission which has as little loss as possible and is free of higher wave-mode types, the invention provides a bisected mode filter, each half mode filter being inserted in a flush terminating manner in the respective end region of two waveguide sections which are to be connected to one another and being held only by narrow, lateral foam webs resting on their inner wall. <IMAGE>

Abstract: A method of encoding and decoding image and/or audio signals includes an encoding step comprising previously preparing a quantization table which has pairs of a sam­pling interval and a quantized difference value, cal­culating a difference value between a given initial value and a sampling point succeeding to the initial value, comparing the calculated difference value with the quantization table, and searching the most matching quan­tization level. The search is started from the sampling point immediately succeeding to the initial value and then stopped upon finding of the matching quantization level. The index of that matching quantization level is transmitted. The decoding step comprises preparing the same quantization table as used in the encoding step, determining the sampling interval and the quantized difference value based on the index received, and adding the quantized difference value to the initial value to obtain a decoded value. In case there are present two or more sampling intervals, the corresponding samples are interporated. As a result, the sampling interval is prolonged in the flat parts of signal and shortened in the steeply changing parts, thereby providing compression fit for human visual and auditory characteristics.

Abstract: The invention relates to a process for the removal of sodium oxalate from an alkaline aluminate liquor from the Bayer process. First the entire aluminium hydroxide product from the stirring is washed to removal all crystalline sodium oxalate, by which means a further precipitation of sodium oxalate in the aluminium hydroxide stirrer is prevented. This increases the concentration of dissolved sodium oxalate to a level which leads to economic removal of sodium oxalate by crystallisation from a side stream. A costly evaporation step is therefore no longer necessary. The sodium oxalate is removed in an amount which corresponds to the sodium oxalate newly formed during the bauxite digestion. A constant concentration of dissolved sodium oxalate in the aluminium hydroxide stirring is maintained in this way. In addition, the aluminium hydroxide stirring can be stabilised (in the state without crystalline sodium oxalate) by adding small amounts of an organic polymer.

Abstract: It has been a problem that the identification of genomic DNA by restriction fragment length polymorphisms is limited, owing to the low level of genetic variation ordinarily detectable by cloned DNA in this method. The invention provides for improved identification by making use of the existence of DNA regions of hypervariability, otherwise called minisatellite regions in which the DNA contains tandem repeat or quasi-block copolymer sequences and the number of repeats or copolymer units varies considerably from one individual to another. It has now been found that many such regions can be probed simultaneously in such a way as to display this variability using a DNA or other polynucleotide probe of which the essential constitutent is a short core sequence tandemly repeated at least 3 and preferably at least 10 times. The probing reveals differences in genomic DNA at multiple high-polymorphic minisatellite regions to produce an individual-specific DNA "fingerprint" of general use for genetic identification purposes. 
     The "core" used is typically a sequence of 6 to 16 nucleotides contained in or having a high degree of homology with a nucleotide sequence of formula in which X is A or G,   in which Y is C or T, or with a 12-15 nucleotide sequence of formula or in which X is A or G, m is 0, 1 or 2, p is 0 or 1, and q is 0 or 1. n which X is as above, P = not G and W = A or G. 
     The invention is particularly useful in paternity and maternity testing, forensic medicine and the diagnosis of genetic diseases and cancer.
