Inventor: ROCHA-SOSA MARIO DIPL BIOL DR
IPC: A01H5/00
Filed: 1988-12-21
Abstract: A DNA sequence of an expression cassette on which the potato tuber-specific regulatory regions are located, and the transfer of this DNA sequence into the plant genome using Agrobacteria as transfer microorganisms are described.

Abstract: PCT No. PCT/DE90/00943 Sec. 371 Date Jun. 18, 1992 Sec. 102(e) Date Jun. 18, 1992 PCT Filed Nov. 30, 1990 PCT Pub. No. WO91/08327 PCT Pub. Date Jun. 13, 1991.A process and apparatus are disclosed for controlling the flow of operations in electroplating plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes. In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts which pass through the plant in succession and/or the distances between these parts are detected and the application of the electroplating currents is controlled as a function of these positions and/or distances by switching the anodes on and off, in such a manner that the flux density is approximately the same in all regions of the parts.

Title: Flocculation-filtration procedure - by sepg. suspensions of fine particles by mechanically mixing with flocculant in flake or honeycomb form and using filter-press
Inventor: APFELBAUM HELMUT
IPC: B01D33/04
Filed: 1990-01-04
Abstract: In a novel flocculation-filtration process, the flocculant is added to the suspension as a prepared material with a flake or honeycomb structure, and the resulting combination is mechanically mixed so that the particles in the suspension become attached to  the flocculant material. A long-chain polymer (poly-electrolyte) is added to the flocculated and precipitated solid material before it is conveyed to the filter press for drying. The solid material may be given a post-treatment in a vessel to which an oxidation or reduction agent and/or a long-chain tenside is  added. USE/ADVANTAGE - This invention is used in the separation of colloidal suspensions, such as especially sewage sludge, mixtures of water and clay, dredger mud, industrial sludges etc., whose disposal is problematic due to the presence of dangerous components. An efficient separation is provided so that the suspended particles can be separated and dried and can be disposed of separately from the remaining liquid and in a safe manner.

Title: Process for combining dental metal framework items - using paste-form hardenable mixt. of precious metal solder powder and combustible binder
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61K6/00
Filed: 1990-06-25
Abstract: Dental bridge framework parts are made in the mouth on framework parts, or on working models using a paste-form hardenable mixt. of precious metal solder powder and a combustible binder. The solder powder is composed of (wt.%); Au 40-90; Ag 5-50; Pt or Pd 2-20; and Rh or Ir 0-10 and is of spherical or splinter shaped particles of average particle size 10-250 microns.
