Title: Sepn. of strongly and weakly dissociated cpds. - by sorption in ion exchanger bed and specified regeneration
Inventor: VAJNA SANDOR DR
IPC: B01J47/00
Filed: 1979-10-17
Abstract: Sepg dissolved weakly dissociated cpds from strongly dissociated cpds in relatively small amts is based on sorption, where the soln is passed through a washed ion exchanger with counter ions in an equilibrium with the counter ions of the solution. Sorption of the weakly dissociated cpd is combined with a free passage of the strongly dissociated cpd. The ion exchanger is regenerated by washing out the adsorbed cpd. This method can be applied whether the two cpds have a common ion or not. It results in a more concentrated prod soln.

Title: Domestic and industrial sludge disposal - using wedge type filter modules loaded in suction trucks
Inventor: RUHNKE SIEGFRIED
IPC: C02F11/128
Filed: 1980-02-08
Abstract: The parent patent described a system of converting aq. sludge from domestic cesspits or industrial waste basins into a solid material by two drying stages. The disposal of industrial and domestic sludge is facilitated by transferring it to filter modules, assembled in trucks, each filter consisting of e.g. a frame with two wedge-type bag filters. The filter modules can also use open-pored plastic foam instead of the textile filter cloth. This reduces the handling operations to a minimum. The large available filter area speeds up the dewatering process.

Title: Three=dimensional electrodes made by contour copy milling - where two=dimensional template provides dimensions in three coordinate directions
IPC: B23Q35/127
Filed: 1980-03-25
Abstract: A two-dimensional template is scanned by a photocell to obtain a two-dimensional contour (2) in the XY coordinate plane of the workpiece. The template also has marked points (A,B,C) indicating a change in the pitch of the third, Z-direction. At points (A,B,C) a programmer is used to store the X, Y and Z dimensions, and also to measure the distance between the points. The programmed data are then used to move a milling cutter along a desired path. Points (A,B,C) are pref. at the beginning and end of each change of pitch occurring in the Z-dimension, i.e. the height; and straight lines between the points are pref. used to define the pitch of the cutter in the Z-direction. A two-dimensional template can thus be used to provide three-dimensional data stored eg. on punched tape or in cassettes and used repeatedly in the successive mfr. of several electrodes with identical profiles.
