Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

 Appl.No 03148843.9 Applicant Wang Rui Inventor Wang Rui
A nanometer anti SARS mask and insulating clothing are made by coverage type nanometer cloth soaked with nanometer particle. The invention adopts macromole polysaccharide, which can combine with virus protein rapidly and effectively as material for preparing nanometer polysaccharide colloid. The average particle parameter is smaller than 100 nanometers in the nanometer polysaccharide colloid. Dips a common non-nanometer cloth in the nanometer polysaccharide colloid and dries it into the coat type nanometer cloth. Four layers coat type nanometer cloth laminate with the two layers common non-nanometer cloth into integrated composite cloth for making mask and insulating clothing. It has a super powerful absorption and insulation function to virus(SARS coronavirus is included) and favorable air permeability function, thus can effectively prevent the virus be passively absorbed into the body.

A face mask comprising an optically transparent or optically semi-transparent mask body is provided. The face mask includes a periphery about an edge of the optically transparent or optically semi-transparent mask body and straps which are attached to the mask body proximate to the periphery or attached to the periphery for releasably retaining the mask on a user's face, the mask body including: an inner layer, which is an optically transparent or optically semi-transparent material with a plurality of passageways therethrough, and which has an inner surface and an outer surface; and a fiberglass fabric layer which abuts the outer surface of the inner layer and which comprises fiberglass ribbons. The fiberglass fabric may be functionalized with a visible light photocatalyst, which may be low iron oxide, iron-doped titanium dioxide.
