Inventor: COHEN STEVEN ALAN
IPC: C08F6/10
Filed: 1989-05-22
Abstract: The method for separating from a mother liquor con­taining at least two liquids, one of the two liquids including the steps of:
     (a) forming a precipitatable complex from one of the liquids and a complexing agent;   (b) precipitating the precipitatable complex from the mother liquor; and   (c) recovering the second liquid from the remaining mother liquor.   
     Typically, the two liquid substances are tetrahydrofuran and toluene and the complexing agent is titanium tetrachloride. The precipitatable complex is TiCl₄·2C₄H₈O or TiCl₄·C₄H₈O. Preferably, a cooling step is included in the method to enhanc the removal of the precipitatable complex. Superfractionation of the remain­ing liquor in distillation columns enables one to recover toluene, hexane, titanium tetrachloride and tetrahydrofu­ran. An apparatus for carrying ou the method of recover­ing solvents is also disclosed.

Abstract: There is disclosed a dot pattern data generating device including: a character generator, constructed to be readable by character code data, for storing data representing a character pattern according to existence or non-existence of dots; a region readout circuit (11) for reading a local pattern of a given region with one concerned pixel being centered from a character dot pattern read from the character generator; an arithmetic circuit (12-15) for computing horizontal and vertical sizes from the local pattern; and a pattern generating circuit (17) for generating a plurality of dot with respect to one dot of an original pattern on the basis of the horizontal and vertical sizes. Based on this construction, configurations―left down, right down, left up or right up―of the dots shaping an oblique line are judged from the horizontal and vertical sizes by an arithmetic operation. The character pattern of an enlarged size is generated at a high velocity without enlarging stepped portions of the oblique line by generating enlargement dots corresponding thereto.

Abstract: Disclosed is an adaptive canceler (32) in which a pipelined approach is used wherein reference signals are divided into two or more sections having concurrent weight adjustment. This architecture allows the speed of adaptive cancellation to be increased and/or the number of reference taps to be increased without loss of cancellation speed. Once a continuous stream of digital data has been established in this architecture, the speed of the adaptive processor is limited only by approximately the processing time of the slowest element. The noise canceled signal may then be converted to the frequency domain in a fast Fourier transform device (34)

IPC: B04B15/12

Abstract: The heavy phase material which is separated off from the liquid in the screw decanter is frequently interspersed with materials which contain solvent, smell strongly and/or are noxious so that said heavy phase material has to be subjected to an appropriate post-treatment in special units in order to be able subsequently to store and/or further process it without difficulty. In addition, as a result of their consistency and their low viscosity heavy phase materials of this kind can in many cases only be transported away from the screw spiral of the conveying screw with difficulty, which can have disadvantageous effects not only on the throughput of the centrifuge but also on the separating effect in the centrifuge. However, according to the invention these disadvantages can be very easily avoided by arranging openings (8,18) in the conical part (5) of the screw body (4) and/or of the screw spiral (6), which openings are connected to feedlines (9,18), which lead outwards, for the fluid media. <IMAGE>
