Abstract: ABSTRACT OF THE DISCLOSURE   An ink jet printer utilizing a smooth surfaced transfer drum is shown as an illustrative embodiment of the invention.  The transfer drum and the print head assembly are mounted between a pair of side plates (only one of which is shown in the drawing).  A print head assembly, which comprises a number of ink jet nozzles, is also mounted between the side plates.  The print head assembly is spaced apart from the drum and the nozzles thereof are spaced at equal distances along a line which is parallel to the axis of the drum.  The print head assembly is movable in fine steps from left to right so that on successive rotations of the drum each nozzle is directed to a new track of a succession of tracks.  After all tracks of the transfer drum have been served by a nozzle assembly, a printing medium, e.g., paper is brought in rolling contact with the drum to transfer the indicia on the drum to the printing medium while the print head assembly is returned to its start-ing position; and thereafter, if required, the drum is wiped clean in preparation for receiving the next page of information.

A particularly preferred salt is calcium nitrate and particularly preferred polymers are high molecular weight anionic polyacrylamide polymers.  Sodium contaminated soils are productively reclaimed by applying to the surface of such soils an effective volume of a treatment solution obtained by diluting the concentrated solution with sufficient water to provide a treatment solution having a viscosity of no more than about 3 cP (25°C).

Abstract: A transconductance amplifier (3) comprises a differential amplifier (T11, T.12), whose collector load is a current mirror (T13, T14, T15, R9, R10) having a current output (8).  A current-source transistor (T10) arranged in the common emitter line supplies a current having a positive temperature-dependence. This current is obtained from a current-stabilising circuit (1). By means of a voltage divider (R7, R8) a fraction of a temperature-independent voltage is applied between the control elec-trodes of the differential amplifier (T11, T12), Which voltage is taken from a voltage-stabilising circuit (2). Depending on the value of this fraction the output current on the output (8) is temperature-independent or has a negative temperature-dependence.

Abstract: ABSTRACT     A process for heating and softening of hard water by direct heat exchange with steam.  The steam is directly sparged into the hard water within a reaction zone and condensed in the water under a pressure sufficient to prevent boiling at the reaction zone tempera-ture.  The heated water is then withdrawn from the reaction zone without substantial vaporization of water and filtered to remove scale precipitates resulting from the heating step.  At least a por-tion of the softened water may be heated to generate wet steam which is then recirculated to the reaction zone and sparged into the hard water therein.

The drive means consists of two driving gears which are each coupled within freewheel having a drive shaft.         The freewheel of the one gear is relative to the freewheel of the other gear.  The drive means changes from the one gear to the other gear by means of side walls and a flange.  The elongation resulting from a strain of the drive means is continuously led out of the system, so that a blocking or a braking of the drive means is avoided.  The tensioning device is especially suitable for the operation of strip curtains or conventional curtains, as well as for curtain systems with large and heavy drive means.

The voltage regulator has a switching transistor connected in series with the field winding of the generator which can operate in a current limiting mode in the event that sensed field current becomes excessive.  The voltage regulator includes circuitry for ensuring that the output voltage of the generator properly builds-up when the field winding is initially excited by the battery.

Abstract: METHOD FOR REMOVAL OF MONOVALENT IONS FROM          ZnSO4 ELECTROLYTE BY ELECTRODIALYSIS                        ABSTRACT          Monovalent ions, especially chloride and fluoride, but also thallium, sodium and potassium are efficiently removed from ZnSO4 electrolyte by electrodialysis.  Monovalent anions are removed using alternating monovalent anion permselective membranes and cation exchange membranes.  Monovalent anions and cations are removed using alternating monovalent anion and  monovalent  cation  permselective  membranes.          Electrodialysis is carried out under turbulent conditions, at up to 60°C, a differential membrane pressure of less than 150 kPa, a current density of 10 to 500 A/m2, and a pH of less than 5.5.  Where both chloride and fluoride are removed a pH of 3.5 to 5.5 is maintained.  Deposition of manganese and zinc on the electrodes is minimized by at least one of a number of means including arranging the membranes such that the end membranes are monovalent anion permselective; selecting a large electrode rinse flow; adding a small amount of soluble antimony and/or cobalt;  and using a cathode made of a material that promotes hydrogen evolution over zinc deposition.   The electrode compartments are preferably rinsed with a 0.1 to 1.0 M Na2SO4 solution at pH 0 to 4.
