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.

Described is an improved technique for causing prerotation of the free
turning rollers in the picker separator means described in the IBM Technical
Disclosure Bulletin 22, 2169 (November 1979).
Shown in the figure is an improved structure for free-turning rollers. Free-
turning roller 1 is a unified structure including a cylindrical portion 2 and molded
wings 3. The structure freely rotates about shaft 4 which is attached to a
rotatable hub (not shown). As shaft 4 is rotated, airflow against wings 3 imparts
rotation to the free-turning roller 1 prior to contact with the paper stack. The
advantage is that prespin occurs without friction or the introduction of other
