Abstract: There is provided a color image processing apparatus in which, by making use of an image reading apparatus of a digital full-color copying apparatus, the designated color to be obtained after conversion is input and stored as component ratio of color-separated image data, and monochromatic image data proportional to the gradation levels, e.g., density, lightness, luminance and so forth are obtained from the color separated image data produced from the original image,the monochromatic image data thus obtained being converted into the color separation data corresponding to the component ratio of the designated color to be obtained after conversion, thereby making it possible to preserve the hue of the designated color and to effect color conversion to the designated color having gradation proportional to the gradation of the original image.

Abstract: The process for preparing 2,2-bis(4-hydroxyphenyl)propane (bisphenol A) by reacting acetone with phenol and decomposing the resultant adduct of bisphenol A and phenol is well known. However, the quality of bisphenol A thus obtained is not always satisfactory. 
     In the process of this invention, the adduct is washed with phenol recovered by decomposing an adduct of bisphenol A and phenol, and then bisphenol A is prepared by decomposing the washed adduct. 
     The bisphenol A prepared by the process of this invention has an extremely high quality and is suitable for the preparation of polycarbonate used for optical parts.

Abstract: The filter plate is provided for filter press filtering elements, in which a plurality of edge-side compressed filtering elements consisting of a support wall (2) having a peripheral plate frame (3) form between them filter chambers (1) with inlets (10) opening out therein for the suspension to be filtered. The filtering elements bear on one or both sides pressing walls (4) which are closely connected to the filtering element on the edge side, can otherwise be moved forwards by a pressure means into the filter chamber and which have on their wall surface facing the respective filter chamber (1) profile projections (5, 9) covered by a filter cloth. Under the filter cloth the profile projections (5, 9) form a channel system for the filtrate connected to an outlet, the pressing wall (4) having an edge strip (6) providing its connection to the filtering element and a bending zone (7) which extends along this edge strip and is deformable at least to the extent of the pressing stroke of the pressing wall. The edge strip (6) is formed by a connection strip which projects obliquely from the support wall (2) in a direction facing away from the plate frame (3) and thereby forms a V-shaped groove (8) between itself and the plate frame (3), the width of which groove is dimensioned such that the two groove walls form a mutual stop limiting the bending deformation of the connection strip.

Problematisch bei Anzeigeeinrichtungen mit Getriebe ist es, daß der absolute Bezug zwischen der Stellung des Zeigers (33) und der Stellung des Rotors (2) im Drehfeldmotor (1) nicht gegeben ist, wenn die Einrichtung gestartet wird und der Bezug verlorengegangen ist. Um den Bezug wieder herzustellen, wird der Zeiger (33) durch ein Drehfeld im Drehfeldmotor (1) in eine vorbestimmte Drehfeld-Richtung gegen einen Anschlag (34) bewegt. Das Drehfeld wird in der Drehfeld-Richtung weitergedreht. Ein durch eine Bewegung des Rotors (2) entgegen der Drehfeld-Richtung im felderzeugenden Teil (4, 5) des Drehfeldmotors induziertes Signal wird erfaßt, und aus der Winkelstellung des Drehfelds bei Auftreten des induzierten Signals wird die Winkelstellung des Rotors ermittelt, bei der der Zeiger am Anschlag anliegt. <IMAGE>

Abstract: Acoustic level sensing apparatus is provided, in which pulses of acoustic energy are transmitted by an electrically energized transducer towards a surface to be sensed, and the electrical output from the transducer following the pulse received by a receiver is digitized and analyzed by a programmed microprocessor to detect a return echo from the surface, so as to produce a digitized echo profile. The digitized echo profile is enhanced by removing narrow peaks likely to correspond with certain types of spurious echo (REMOVE_NARROW_ECHOES_F0), and narrow valleys which may represent fragmentation of a wanted echo (REFORM_FRAGMENTED_ECHOES_F0). Echoes are identified by comparing the profile with a time varying threshold generated derived from a linear regression performed on part of the echo profile (TVT_IN_F2), various different types of comparison being performed and their results combined (ALF_ALGORITHM) prior to selecting the most likely true echo on the basis of the combined results (SELECT_BEST_ECHO_FROM_FILE_3).

Abstract: A method for forming a paper or paperboard web from a fibrous material in the wire section of a paper making machine or equivalent machine comprising a bottom wire loop (2;102) with the main portion of its top run being horizontal or substantially horizontal, and a top wire loop (10;110) working in conjunction with the bottom wire loop; wherein in the method fibre slurry coming out of the headbox (1;101) of the paper making machine is fed to the first part (2a; 102a) of the top run of said bottom wire loop (2;102), which forms the first dewatering zone after which the partly formed fibre layer is led to the second dewatering zone, in the area of which said top wire loop (10;110) moves to cover said partly formed fibre layer in such a way that water removal from the fibre layer continues it least in two stages in the area of said second dewaterlng zone, whereupon the top wire loop (10;110) is separated from the nearly formed web (W) that is led to follow the run of the bottom wire loop (2;102) forward to the next processing stages of the web (W), wherein the method is  characterized  in that in the single-wired dewatering zone (2a;102a), after the initial water removal is carried out through the bottom wire (2;102), water removal through the bottom wire (2;102) is prevented by means of an element group (9; 109) operating in contact with the inner surface of the horizontal top run of the bottom wires; that in said water-removal pre­vention area water is removed from the web (W) through the top wire in the first stage or stages of the double-­wired second dewatering zone, which stages comprise a relatively long, planar wire table extending from the headbox to the forming roll (6 in Fig. 1), or from the headbox to the last supporting element (109 in Fig. 2); and that after the first dewatering stage or stages of the double-wired zone water is removed in a curved double-­wired dewatering zone (b) (Fig. 1) or zones (R o , C) (Fig. 2), after which the web (W) is led to follow the bottom wire (2;102).
