Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Sputter Coated Paper For Electrosensitive Printing
The preparation of electrosensitive printing media has commonly been

It has been recognized that the use of sputtering techniques would produce a
more adherent film as a consequence of the higher energies of the deposited
atoms. This process has not been found practical since the inherent high heat
tends to char or otherwise produce heat-based deterioration of the paper
substrate or the materials with which the paper is treated.
The use of planar magnetron sputtering has produced a highly
adherent aluminum coating on treated paper. The metal-coated paper
for electrosensitive printing was thereby produced without the
necessity of an adhesive primer layer and without damaging the paper.
This coated paper has been used to produce high quality
electrosensitive printing. The same process could be used to produce
electrosensitive print media with other high conductivity metals
being substituted for aluminum.
