Abstract: ABSTRACT OF THE DISCLOSURE           A reagent mixture is admixed with soil to first desorb and then hydrolyze and thereby increase the biodegradability of a toxic or otherwise hazardous polyhalogenated organic compound with which the soil is contaminated.  Essential constituents of the reagent mixture are:  (1) an alkali metal hydroxide, an alkali metal hydroxide/alcohol or alkali metal hydroxide/glycol mixture, or an alkoxide; and (2) a sulfoxide catalyst.  The hydrolyzed compounds can be biologically degraded into compounds which pose little if any hazard to the environment or its inhabitants by naturally occurring or artifically introduced Pseudomonas sp. and other microorganisms with adjustment of soil pH (and perhaps other parameters) to provide a viable environment for the bacteria being carried out after the chemical treatment if inoculation with bacterial cultures is employed.  If a mixture of non-biodegradable and biodegradable contaminants is present, a preliminary biodegradation step can be optionally used to rid the contaminated area of the latter before hydrolysis of the contaminated soil with the reagent mixture is undertaken.

Abstract: ABSTRACT OF THE DISCLOSURE     A data compressor compresses an  input  stream  of  data character  signals by storing in a string table strings of data character  signals  encountered  in  the  input  stream.  The compressor  searches  the input stream to determine the longest match to a stored string.    Each  stored  string  comprises  a prefix  string  and  an extension character where the extension character is the last character in the string  and  the  prefix string comprises all but the extension character.   Each string has a code signal associated therewith and a string  is  stored in the string table by,  at least implicitly,  storing the code signal for the string,  the code signal for the  string  prefix and  the  extension character.   When the longest match between the input data character  stream  and  the  stored  strings  is determined,    the   code  signal  for  the  longest  match  is transmitted as the compressed code signal for  the  encountered string  of  characters and an extension string is stored in the string table.  The prefix of the extended string is the longest match and the extension character of the extended string is the next input data character signal following the  longest  match.          Searching  through  the  string  table  and  entering  extended strings  therein is  effected  by  a  limited  search  hashing procedure.    Decompression  is effected by a decompressor that receives the compressed code signals  and  generates  a  string table  similar  to that constructed by the compressor to effect lookup of received code signals  so  as  to  recover  the  data character signals comprising a stored string.  The decompressor string table is updated by storing a string having a prefix  in accordance  with  a prior received code signal and an extension character  in  accordance  with  the  first  character  of  the currently recovered string.

Abstract: ABSTRACT   The invention relates to an improvement in a method for recovering metal values from copper-containing and/or precious metal containing materials which also contain antimony and/or bismuth in such high quantities as to render working-up of the materials with conventional metallurgical processes difficult or impossible. In accordance with the improvement, the material is subjected to a chlorination volatilization process in a manner to bring the antimony and/or bismuth content of the material to a predetermined low level acceptable for the continued working-up of the material in conventional process stages, while maintaining the metal values of the material in a substantially unaffected form. The volatilization process is best carried out at temperatures of between 450°C and 750°C, preferably between 550°C and 650°C. The chlorination process can be carried out on materials included in the group: sulphidic or oxidic-ore concentrates, matte, speiss, oxidic and metallic inter-mediate products. In certain cases it is convenient to convert the material to another form within the group, for example the matte. prior to carrying out the chlorination process.

Abstract: ABSTRACT OF THE DISCLOSURE          A displaying apparatus uses a raster scanning type display such as a CRT,  wherein vertical and horizontal positions are addressed respectively by an address counter for displaying. A start address is set in a vertical address counter and a horizontal address counter, which are later incremented by a carry from an adder corresponding thereto.  The adder for the vertical address repeats adding operations a predetermined addend data four times in one horizontal blanking period and twice in one vertical blanking period.  The adder for the horizontal address repeats adding operations the predetermined addend data at short time intervals.  By setting the addend data properly, display sizes of characters or pictures on a screen of the CRT can be enlarged or reduced with respect to their original sizes. Moreover, if the start address and addend data described above are renewed at every horizontal line, characters or pictures  in various  angles  in accordance with a perspective can be displayed.

Abstract: ABSTRACT OF THE DISCLOSURE:     Instead of an excitation pulse sequence producing  circuit which is used according to prior art in calculating pulse instants or locations of excitation pulses and pulse amplitudes thereof, an excitation pulse sequence parameter producing circuit is used in a low bit-rate pattern coding device in recursively giving delays of the respective pulse instants to a discrete impulse response sequence to provide a system of delayed impulse responses and in orthogonalizing the delayed impulse response system into an orthogonal system of system elements,  Meanwhile, the pulse instants are determined with element amplitudes or factors calculated for the respective system elements by the use of the system elements and each segment of a discrete pattern signal sequence.  The pulse instants and the element amplitudes are used as parameters descriptive of the excitation pulses.  Alternatively, the pulse instants are determined one at a time after quantization of each of the recursively determined element amplitudes.  Preferably, the discrete impulse response sequence and the segment are weighted in consideration of auditory or like sensual effects.  In a counterpart decoder, the pulse amplitudes are calculated by the use of the pulse instants and the system elements which are calculated by using the pulse instants and another parameter sequence which, in turn, is derived in the coding device from the segment in the manner in the art of multi-pulse excitation.
