Granted: 2003-10-07
Abstract: L'invention porte sur un article absorbant jetable tel qu'une serviette hygiénique, un protège-slip ou un coussinet d'incontinence pouvant être placé dans un sous-vêtement. Cet article absorbant comprend une feuille supérieure, une feuille inférieure, une partie centrale absorbante et un élément de raidissement. Cet élément confère à l'article un état initialement raidi lorsqu'on le place dans un sous-vêtement. L'article ayant été soumis à des forces exercées par le corps de l'utilisateur, l'élément raidisseur perd ensuite sa rigidité renforcée initialement et l'article devient plus souple.

IPC: G01F1/66
Filed: 2000-10-05
Granted: 2004-05-04
Abstract: A method of correcting reading of a non-contact solids flow meter measuring solid particulate flow where the solid particulate product enters the flow tube at one end and flows past a sensor and then exits the flow tube. The sensor for the flow meter is very sensitive and not only can sense particulate flow, but can also pick up system machinery motion such as the rotation of a screw conveyor or other moving machinery parts as product flow and provide a system output reading in excess of the actual flow rate. In addition, if the product flow creates dust during the initial calibration process, and the dust is controlled at the actual installation, the system output reading may indicate a flow rate substantially less than the actual flow. The calibration method of this invention uses the original calibration or performance curves to accurately correct the output readings.

Title: A method for producing decorative components having an outer elastomeric layer that is integral with an inner foam layer
Inventor: CHANG L PATRICK
IPC: B29C41/08
Filed: 2000-12-15
Granted: 2010-04-27
Abstract: The method of the present invention is particularly suited for of making decorative objects in a mold cavity. The method enables one to form a decorative component having an outer elastomeric layer that is integral with an inner layer of foam. Because the chemical formulation for the outer layer and the inner layer is identical, other than the inner layer includes a foaming agent, the decorative component does not suffer from the drawbacks of the previous methods such as, for example, poor adhesion between the elastomeric layer and the foam layer causing delamination of the two layers, sinks or holes in the foam layer leading to imperfections in the elastomeric layer, and bleed through to the elastomeric layer from the foam layer. The method permits the mold to be pre-coated with an in-mold paint prior to the molding process. Coatings can also be applied after demolding the resulting part.
