Abstract: 1. A process for recovering high-purity graphite from natural graphite by heating fine-particle crude or prepurified natural graphite with an aqueous alkaline solution under pressure, diluting with water, washing of the treated graphite with hot water, acid secondary treatment, washing of the acid-treated graphite with hot water and drying, characterised in that the treatment with the aqueous alkaline solution is carried out at a pressure of from 20 to 40 bar and at temperatures of between 220 and 280 degrees C, wherein 1.5 to 3 times the amount of the theoretical amount of alkali metal hydroxide and/or alkali metal carbonate required to transform the gangue contained in natural graphite into soluble compounds is used, the suspension obtained is cooled to a temperature of from 70 to 90 degrees C, is diluted with water and/or an aqueous sodium chloride solution having approximately the same temperature as the suspension at a ratio of from 1:1 to 1:2, the alkaline-aqueous solution is separated from the graphite at a temperature of above 50 degrees C, the separated graphite is washed with a neutral aqueous medium at a temperature of from 50 to 80 degrees C until reaching the neutral point of the washings and subsequently is treated a second time with an acid aqueous solution at a temperature of between 90 degrees C and 45 degrees C, the graphite is again separated from the acid suspension obtained and is washed neutral with water, preferably deionised water.

Abstract: A message packet router is described that performs the functions of determining if a message packet is addressed to circuitry associated with the router, of routing message packets to their distination if possible and of storing message packets that cannot be routed on because of circuit conflicts. The router also provides additional functions of merging message packets addressed to the same destination, of saving the state of the router at each significant point in the message routing cycle, and of running the entire routing cycle backwards. This later feature makes it possible to broadcast message packets selectively to certain processors in the array.

Abstract: The invention specifies a simple reproduction method with improved pronunciation for voice-controlled systems with text-based speech synthesis even when the stored train of characters to be synthesized does not follow the general rules of speech reproduction. According to the invention, the method of "copying" the original spoken input text into the otherwise synthesized reproduction text, which is the current state of the art, is avoided, which will significantly increase the acceptance of the user of the voice-controlled system due to the process invented. More specifically, when there is actual spoken speech input that corresponds to a stored train of characters, the converted train of characters is compared to the speech input before reproduction of the train of characters described phonetically according to general rules and converted to a purely synthetic form. When the converted train of characters is found to deviate from the speech input by a value above a threshold value, at least one variation of the converted train of characters is created. This variation is then output instead of the converted train of characters as long as this variation deviates from the speech input by a value below the threshold value.

Abstract: The inventive conduit holder is used to mutually fix at least two conduits extending side by side. The holder consists of a lower part (1) with one or several retaining shells (3,3') which are used to receive said conduits (5); an upper part (2) with corresponding counter shells (4,4') which are used to enclose the conduits (5) and locking means connecting the upper part (2) to the lower part (1). In order to prevent axial displacement or torsion of the inserted conduit, a bore hole is provided (13) and arranged between two adjacent retaining shells (3, 3', 4, 4'), running perpendicular to the center axis thereof. The diameter of the bore hole (13) is dimensioned in such a way that the cylindrical surface of said bore hole cuts into the retaining shells (3, 3',4, 4') . A pin (14) is also provided, whereby said pin is driven into  the bore hole (13) when the conduits are enclosed (5) and the upper part (2) is connected to the lower part (1). The wall of the conduit (15) is deformed when the pin (14) is driven inwards by virtue of the fact that the retaining shells are only slightly penetrated by the bore hole (13). Said deformation can be permanent or elastic according to the type of material used for said conduit and causes the conduits (5) to be fixed in an inserted position.
