Title: Sitosterol and its glycoside(s) with improved bio-availability - are in the form of microemulsions using lecithin as the carrier, isopropyl-myristate as the emulsifier and isopropanol as co-emulsifier
IPC: A61K9/107
Filed: 1990-12-01
Abstract: Sitosterol and its glycosides of improved bioavailability are in the form of microemulsions using lecithin as the carrier. Pref. the microemulsions contain isopropylmyristate as emulsifier and isopropanol as co-emulsifier. The microemulsions consists of 21-23% lecithin, 15-16% isopropanol and 7.0-7.5% isopropanolmyristate in water as the dispersant. USE/ADVANTAGE - Beta-sitosterol is practically non-toxic and has antipyretic, cholesterol-reducing and antiproliferative properties, and does not accumulate anywhere in the body, but as a result of its low water solubility is not resorbed well from the gastro-intestinal tract. When sitosterol and its glycosides are in the form of microemulsions using lecithin as carrier, the bioavailabilty is much better. The microemulsions are semi-solid, transparent and can be stored for long periods without changing. When given p.o. to rats, the resorption of beta-sitosterol from a suitable microemulsion was 24%, while from a suspension in distilled water, the resorption was 18%

Patent DE-4103088-A1 (DE)
Inventor: WELKER HEINRICH
IPC: E04F19/06
Filed: 1991-02-01
Abstract: The device serves to form regularly continuing edges on or in buildings, in particular drip- or water-guided edges in balconies, overhanging components, parapets and plaster or joint-boundary edges. It is characterised by an angle section strip (1) made of plastic which can be fixed to the building or building part when forming a building edge by means of knifing filler, plaster or the like. Said angle section strip comprises a first leg (2), which defines the building edge after the strip has been secured, and a second leg (3) extending transversely with respect to the first leg (2). This second leg (3) forms with the first leg (2) a strip edge (4) and is joined to a coarse-mesh latticework (5) which facilitates the strip fixing by means of knifing filler or plaster. The first leg (2) is also joined to a coarse-mesh latticework (6) extending forwards over the strip edge (4). <IMAGE>
Patent DE-4108817-A1 (DE)
IPC: C23F15/00
Filed: 1991-03-18
Abstract: Reducing corrosion and lime deposits caused by water impurities on surfaces exposed to water is performed by the presence of magnetically treated water. It is found that the reduction of corrosion or encrustation is much more effective if water from a magnetically treatment unit (1) is passed over the affected surfaces to flush them as directly as practically possible and at as high a flow speed of practically possible. Water that has been used to flush these surfaces is recycled through the magnetic treatment apparatus (1) by means of a pump (8) and used to flush the affected surface again. Deflecting devices of the magnetically treated water are useful for flushing the affected surfaces effectively. A helical heat deflector inside a pipe can produce a spiral flow in a pipe for bringing as much of the treated water into contact with the walls of a pipe. A system of nozzles (10) is useful for directing flows of treated water along the walls of a tank. A spiral loop (12) with perforations facing a heating element or a cluster (11) of heating elements is useful for directing magnetically treated water at surfaces of heating elements. Magnetically treated water can similarly be used in cooling towers and air treating installations.
