Title: Bristles having shaped surface, method of obtaining them and brush or similar tool for cleaning tooth interstices
Inventor: WEIHRAUCH GEORG
IPC: B29C48/16
Filed: 1996-08-22
Abstract: The invention pertains to a process for producing surface-structured synthetic bristle material by extrusion of a monofilament. Before or during extrusion, granules are added to a first thermally melted synthetic material which constitutes the principal component of the monofilament. The granules consist of a second synthetic material with a higher thermal stability than the first. The grain size of the granules is such that the monofilament when subsequently stretched undergoes a more marked transverse contraction in cross-sections with few or no granules than in cross-sections which have granules. The invention also pertains to a surface-structured bristle made from the principal component first synthetic material in which granules of the second synthetic material are embedded so as to be more or less completely covered and form a structure at the bristle surface. The invention futher pertains to a brush, in particular a toothbrush or interdental cleaning device, with a plurality of bristles gathered as required into bundles, at least some of the bristles having the structure indicated above.

Title: Method of preventing a possibility of obtaining satisfactory record of video signals
Inventor: QUAN RONALD
IPC: H04N9/44
Filed: 1996-05-01
Abstract: In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error. This color stripe process is defeated first by determining the location of the video lines including the color stripe process, either by prior experimentation or by on-line detection. Then some or all of the lines including the modified color bursts are modified so as to render the overall video signal recordable. The modification is accomplished in a number of ways, including phase shifting the color stripe burst into the correct phase, replacing some of the color stripe bursts or a portion of particular color stripe bursts so that they are no longer effective, and mixing the color stripe burst with color stripe signals of the correct phase so as to eliminate most or all of the phase error present. The modified color bursts are defeated, in other versions, by modifying the horizontal sync pulse signals immediately preceding the modified color bursts so that the modified color bursts are not detected by a VCR and hence have no effect.

Title: Method for transforming slag derived from non-iron metallurgy
Inventor: EDLINGER ALFRED
IPC: C22B23/02
Filed: 1999-03-16
Abstract: The invention relates to a method for transforming slag derived from non-iron metallurgy, especially of primary and secondary Ni and Cu foamed slags while recovering and/or enriching the non-iron metals and constructing synthetic puzzolans. The liquid oxidic slags are reduced in a first reduction step by means of a metal bath, said bath containing Cu and/or Ni and optionally Co, with gases, e.g. cracked gas, which contain H2 and CO. The redox potential of the CO/H2 mixture is reduced by adding 10 to 40 vol. % H2O vapor and/or CO2 in order to prevent the reduction of Fe oxides. Afterwards, the remaining slag which is free of Cu and Ni is subsequently reduced by means of an iron bed while using carbon to reduce the Fe oxide portion in order to produce a slag which is free of Fe and nonferrous heavy metals.

Filed: 1999-09-17
Abstract: Lovastatin, pravastatin, simvastatin, mevastatin, atorvastatin, and derivatives and analogs thereof are known as HMG-CoA reductase inhibitors and are used as and antihypercholesterolemic agents. The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to Aspergilus, Monascus, Nocardia, Amycolatopsis, Mucor or Penicilium genus, some are obtained by treating the fermentation products using the method of chemical synthesis or they are the products of total chemical synthesis. The purity of the active ingredient is an important factor for manufacturing the safe and effective pharmaceutical, especially if the pharmaceutical product must be taken on a longer term basis in the treatment or prevention of high plasma cholesterol. The accumulation of the impurities from the pharmaceuticals of lower purity may cause many side effects during the medical treatment. The present invention relates to a new industrial process for the isolation of HMG-CoA reductase inhibitors using so-called displacement chromatography. Use of the invention enables to obtain HMG-CoA reductase inhibitors of high purity, with high yields, lower production costs and suitable ecological balance.

Title: Pump which can be actuated by a hand lever
Inventor: VON SCHUCKMANN ALFRED
IPC: B05B11/00
Filed: 2002-03-06
Abstract: The invention relates to a pump (4) which can be actuated by a hand lever, is used to spray liquids (3), and can be especially placed on bottles (1) or the like. Said pump comprises a piston (13) which can be linearly displaced in a chamber (17) on the side of the housing, against the force of a compression spring, and which is used to spray the liquid (3) out of a mouthpiece nozzle (24). The piston (13) is coupled to the pivotably positioned hand lever (6) by means of a connecting tractional member (G) in such a way that the pivoting movement of the hand lever (6) pulls the piston (13) in the direction of the liquid (3) moving towards the mouthpiece nozzle (24). The connecting tractional member (G) extends from the rear side (49) of the piston (13), parallel to the travel of the piston and in the direction of the mouthpiece nozzle (24). A section (48) is provided on the rear side (49) of the piston (13), as a carrier for the same (13), forming a single element therewith. In order to obtain a solution which is advantageous in terms of construction and handling, bearing journal sections (6') of the hand lever (6) are suspended in open slits (9), loaded by the compression force of the spring (15) towards a slit end, and the opening (O), which is partially surrounded by the frame-shaped connecting tractional member (G) in the longitudinal direction of the pump, can be pivoted, on the hand lever side of the compressed spring (15), on the end (25) of the supporting tube (26) which is to receive the mouthpiece (23).
