Title: Polysaccharide from Nerium oleander - having immune-stimulating effect and stimulating tumour necrosis factor synthesis
Inventor: OEZEL HUESEYIN ZIYA PROF DR
IPC: C08B37/00
Filed: 1989-05-16
Abstract: Polysaccharide is of formula (I). R = middle degree of methylation of 90%, independent of H, alkali(ne) earth cations, with 30,000-40,000 D M.wt., determined by HPLC-GPC. Recovery of (I) is also claimed. USE/ADVANTAGE - (I) is used as an immune stimulant (claimed). In an example, leaves of Nerium oleander were crushed and boiled with distilled water for 3 hrs., solids were filtered off, cooled to room temp. and filtered again. The filtrate was mixed with 96% ethanol, and the soln. left for 12 hrs.. The gel suspension formed was filtered off and the residue dissolved in distilled water. The process of forming a gel suspension, filtering it off and dissolved in distilled water was repeated twice producing a crude extract. This was dissolved in water and eluted with distilled water giving two fractions. The first fraction contained a mixt. of (I) of M.Wt. 17,000-120,000 D and the second fraction contained low molecular poly- and oligo-saccharides of M.wt. of up to 10,000 D.

Title: Fully automatic control of fermentation during beer mfg. - gives accurate measurement of the extract content to allow control and assessment of the process
Inventor: MIETH HANS OTTO DIPL ING
IPC: G01N33/14
Filed: 1989-06-22
Abstract: A process and equipment for controlling the pressure and temp.  of a fermenting substrate and continuously recording the extract content in the substrate are described. The process ensures the continuous recording of the extract content in the substrate provides sufficient accuracy for the control and assessment of the fermenting process. At the start of the process the total mass of the fermention substrate is measured with a first range of measurement. The first quantity measurement is balanced out through a similarly large opposing quantity and the control of the fermentation process depends on the difference between a quantity measurement for the instantaneous total mass and the initial quantity measurement. The difference compared to a second range of measurement is recorded and in contrast to the first range of measurement is smaller and in fact in the ratio of the initial measured quantity to the max. difference at the end of the process. USE/ADVANTAGE - For fully automatic control of fermentation during beer production. The accuracy of measurement of the extract content in the fermentation substrate is sufficient for control and assessment of the process.

Title: Solvent-based paint stripper - contg. natural saponin and soap and/or surfactant, pref. as gel for universal application
Inventor: SCHEIDEL HERMANN
IPC: C09D9/04
Filed: 1989-07-11
Abstract: Solvent-based paint stripper (I), esp. (I) contg. soaps and/or surfactants, contains 0.5-5% of a 1-20% aq. soln.  of natural saponins and, instead of pure saponin solns., mixed prods. of saponins and detergents and/or emulsifiers and/or wetting agents, in addn. to soaps, emulsifiers and/or conventional wetting agents. (I) is thickened to a gel by the combination of soaps, emulsifiers and/or wetting agents with saponin formulated with polar and apolar solvents. The gel intrinsically liquefies if the balance between apolar and polar solvents or between the solvent content and the soap-wetting agent-saponin mixt.  is changed so that one or more solvents migrates into the paint. (I) contains 3-15% dearomatised hydrocarons, which promote penetration and gel formation. The soaps may be entirely replaced by emulsifiers and/or other synthetic surfactants to give an alkali-free, neutral (I); and the soaps and synthetic surfactants may be entirely replaced by natural saponins to accelerate biodegradation in purificn. plant. USE/ADVANTAGE - (I) is universally useful, i.e. suitable for stripping various types of paint from both horizontal and vertical surfaces.
