Abstract: Image data processing circuitry is provided for processing image data items, representative of the respective density values of pixels making up an original image, to derive output data items for determining the density values or pixels making up a corresponding output image. The circuitry includes storage means (11) for storing successive sets of such image data items relating respectively to such original image pixels, each of which sets is made up of a data item relating to an object pixel (D m,n ) and further data items relating respectively to peripheral pixels, adjacent to the said object pixel; 
   calculation means (12) operable to receive image data items of such a stored set and to produce a modified object pixel data item (D′ m,n ) derived from the said image data item relating to the said object pixel (D m,n ) of the set in dependence upon the respective differences in density values between that image data item (D m,n ) and the said further data items of the set concerned; 
   comparison means (13) operable to compare the density value of the object pixel data item (D           ′       m,n             ) with a threstold value (TH₁) and, in dependence upon the result of such comparison, to determine such an output data item (O m,n ) corresponding to the object pixel concerned; and 
   error correction means (14, 15) operable to determine an object pixel error (E m,n ) representative of the difference in density values between the said modified object pixel item (D′ m,n ) and the said output data item (O m,n ) and operable also, in dependence upon that error (E m,n ), to modify such further data items in the said storage means (11) so as to enable the circuitry to compensable for such a determined object pixel error when processing a subsequent set of such image data items. 
     Such circuitry can facilitate faithful reproduction of half-tone original images such as photography.

Date Nov. 14, 1991.According to a process for operating a slot machine that works as a roulette wheel, the gambler determines the amount of the stake by introducing coins then by pressing selection keys. A microprocessor determines the result of the game by means of random algorithm. When the chosen number is hit, the microprocessor instructs the coin distributing unit to eject the main prize. When a chosen number is hit, the microprocessor drives another processor with a random generator. The random generator determines, depending on a written algorithm, a gain multiplier which is multiplied by the amount of the stake on the number that was hit. The payment unit is then instructed to distribute an amount in coins which corresponds to the product of the stake on the number that was hit and the gain multiplier.

Abstract: The invention relates to a process for removing water and, if required, substances soluble in hydrophilic solvents from finely divided solids, for example sewage sludge. The solids are washed in steps I, II, III in counter-current by the solvent and concentrated. During this, prior to the termination of the counter-current washing, at least one part-stream of the solvent/water mixture is drawn off and fed to a distillation column D for concentration of the solvent. The solvent still adhering to the solids is then preferably separated off in an evaporator V. The separated-off solvent is likewise fed to the distillation column D for concentration and then, together with the solvent recovered from the stripped solvent-containing water, used for the counter-current washing. <IMAGE>
