Abstract: PCT No. PCT/DE93/00304 Sec. 371 Date May 4, 1994 Sec. 102(e) Date May 4, 1994 PCT Filed Apr. 2, 1993 PCT Pub. No. WO93/19635 PCT Pub. Date Oct. 14, 1993.A diamond without plate is described, in which the facets of the upper part are more slanted toward the girdle level than the facets of the lower part. To create a diamond that, with the least possible quantity of material, gives one an impression of hardness and clarity when looking down on it, the angle between one of the equally large upper part facets and the preferably polygonal girdle level as well as the angle between one of the equally large lower part facets and the girdle level is chosen in such a way that seen from above, the girdle level appears in essentially homogenous, planar brilliance in which a central, shining star is imbedded.

Title: Top circulation line cooling for a modified cook digester.
Inventor: RICHARDSEN JAN T
IPC: D21C7/14
Filed: 1993-10-08
Abstract: In the production of cellulose pulp (e.g. kraft pulp) utilizing a continuous digester having a number of different feed points for cooking (e.g. white) liquor and utilizing a high pressure feeder, the volume of cool white liquor that is applied to the feed system is reduced compared to conventional processing. This can cause excessive hammering, and damage the high pressure feeder and adjacent piping and equipment. In order to avoid this, liquid being recirculated from the top of the digester back to the high pressure feeder is cooled by passing it into a heat exchanger into heat exchange relationship with a cooler liquid, with the flow of coolant automatically controlled by sensing the temperature of the recirculated liquid. The temperature in the feed system can further be lowered by cooling the cooking liquor before it is added to the pulp slurry, as by passing it to a flash tank so that its temperature is reduced at least 10 degrees C., and the flashed steam can be used in an evaporator.

IPC: C02F1/52
Filed: 1994-03-10
Abstract: In the process for separating off organic pollutants, in particular biomass and non-biodegradable substances, from waste water (effluent), precipitants and flocculants are added to the waste water, the precipitant used being a combination of soluble iron compounds and aluminium compounds. Starting from a waste water having a COD of approximately 1300 mg/l, the precipitant used is a combination of this type of iron(III) chloride and aluminium(III) chloride, with which concentrations of about 650 mg/l of Fe<3+> ions and about 200 mg/l of Al<3+> ions are established. Depending on the solids content in the waste water, flocculant is added in an amount corresponding to a concentration in the waste water in the range from 0.1 to 3.0 mg/l, a pH in the region of about 6.0 being established. By the addition of an aluminium compound additionally to the iron compound, the concentration of the iron can be disproportionately reduced with constantly good COD decrease; moreover, the floc structure improves. <IMAGE>

IPC: G03G9/12
Filed: 1994-04-07
Abstract: The invention is a negative charge director (18) for liquid electrographic toners. The charge director (18) comprises a very weakly associating, charged functional group (13) covalently bonded in the resin coating of the toner particle (11), and a very strongly chelating, preferably neutrally charged, molecule (15) dispersed in the liquid phase (17) to achieve charge separation. The weak association site (14) on the resin is prepared, via well-known ion-exchange chemistry, in the metal form desired. Preferred metals are those with no regulatory, health or environmental issues, such as K +, Na +, Ca²⁺, Al³⁺, Zn²⁺, Zr⁴⁺, Mg²⁺, ammonium (NH₄ +), and organic cations. 
     The cation-associated resin is brought into dispersion with the solution phase chelating molecule (15). When this is done, the equilibria that compete for the cation are such that it is released from the resin and bound in the chelate. The toner particle is left with a net negative charge (18) which is permanent, but which is balanced by an equal, opposite charge on the chelated cationic species (19) in the continuous phase. Preferably, there are no other sources of charge in the dispersion, and there is no excess of charge carriers in the continuous phase which would interfere with development.
