Title: Stabilization of isothiazolone
Inventor: HIGBEE VALERIE LYNN
IPC: A61K31/425
Filed: 2000-05-05
Abstract: The present invention provides a highly stable formulation having broad spectrum preservative properties. The formulation is an admixture of dialkan ol- substituted dimethyhydantoin, one or more isothiazolone compounds, a hydanto in stabilizer, and a hydroxyl solvent. The formulation is highly stable in pH ranges of about 4 to 8. Preferably the active components are dimethyloldimethylhydantoin, chloromethyllisothiazolone and methylisothiazolone, and the stabilizer dimethylhydantoin. The formulation h as a free formaldehyde content of less than 0.2 % and is beneficial for preserving various aqueous compositions, including household and industrial products, and especially personal care products, which require a less acidic  pH range than in which isothiazolone is stable in the presence of cationic salts.
Patent CA-2373487-A1 (CA)
Title: Label and method for producing it
Inventor: SPEICH FRANCISCO
IPC: D06H7/00
Filed: 1999-07-27
Abstract: The label has two non-folded longitudinal sides (1) and two foldable narrow sides (2) and consists of a backing fabric (11) with warp threads (4) and basic picks (5), in addition to embroidery picks (12) made of a fusible thread material forming the pattern.      The embroidery picks (12) forming the pattern extend parallel and at a distance to the unfolded longitudinal sides (1) of the backing fabric (11). The non-folded longitudinal side (1) is an edge of a cut formed in the backing fabric outside the area (13) of the pattern.      The label has the advantage that the edges of the cuts on the longitudinal sides are soft and skin friendly thereby substantially improving wearing comfort. Due to the fact that the edge of the cuts produced by the basic picks have practically no brows and the picks extend parallel in relation to the longitudinal side of the labels, an even appearance is achieved on the entire length of the label since the picks cover evenly the back part.

Abstract: The invention relates to a method for the real-time rendering of large volum e data sets. According to said method, a subset of volume data is selected in order to generate said rendering by means of said subset. The aim of the invention is to realize a maximum rendering repetition at a limited volume data charge rate and storage rate. To this end, volume data of different resolutions are used for the rendering. The low-resolution volume data mainl y refer to areas of rendering that are less interesting for the viewer. For example, said areas of rendering are further away from the viewer than other  areas which in turn are represented by higher resolution volume data.</SDOAB >

Filed: 2000-11-29
Abstract: The present invention relates to antimicrobial compositions, methods for the production of these compositions, and use of these compositions with medical devices, such as catheters, and implants. The compositions of the present invention advantageously provide varying release kinetics for the active ions in the compositions due to the different water solubilities of the ions, allowing antimicrobial release profiles to be tailored for a given application and providing for sustained antimicrobial activity over time. More particularly, the invention relates to polymer compositions containing colloids comprised of salts of one or more oligo-dynamic metal, such as silver. The process of the invention includes mixing a solution of one or more oligodynamic metal salts with a polymer solution or dispersion and precipitating a colloid of the salts by addition of other salts to the solution which react with some or all of the first metal salts.

Abstract: Coefficients of an adaptive filter are updated in response to a far-end signal and an error signal by using internal coefficients. The adaptive filter operates for generating a first pseudo echo signal in response to the far-end signal. A main filter operates for generating a second pseudo echo signal in response to the far-end signal. A decision is made as to whether or not the coefficients of the adaptive filter and the internal coefficients in the updating process should be initialized. In cases where it is decided that the coefficients of the adaptive filter and the internal coefficients in the updating process should be initialized, a tap length of the adaptive filter and the updating process is set to a non-original value smaller than an original value, and then initialization of the coefficients of the adaptive filter and the internal coefficients in the updating process is executed. The coefficients of the adaptive filter are transferred to the main filter when certain conditions are met. In cases where transfer of the coefficients of the adaptive filter to the main filter is executed after the tap length of the adaptive filter and the updating process is set to the non-original value, the tap length of the adaptive filter and the updating process is set to the original value, and then initialization of the coefficients of the adaptive filter and the internal coefficients in the updating process is executed.
