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.

Breaking and Retrievably Storing Glass Tubing
A continuously rotating drum breaks glass tubing into uniform lengths and
places the pieces into sequential compartments from which they may be
retrieved by, for example, the time of manufacture.
A continuously rotating drum carrying six pairs of clamps receives glass
tubing from drawing equipment and places uniform lengths into compartments of
a linearly moving container. The clamps are synchronized with the drum rotation
to close at the entry position and remain closed until the exit position. Thus,
glass tubing is captured at the entry position, snapped into lengths determined by
the drum side dimension and then released to fall into a compartment.
