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.

Valve Vent Reservoir
The above drawing shows a device suitable for coupling to the valve of drop
generator (not shown) to solve problems associated with thermocycling of the
drop generator in an ink jet print system.
The device includes an ink reservoir interconnected by a pipe to the valve of
a drop generator (not shown). The reservoir may be closed with a breather
opening for venting the reservoir to atmosphere.
The reservoir must be disposed below the centerline of the nozzles
(approximately two inches). The configuration will enable gravity to pull ink from
the drop generator into the reservoir. The capillary phenomenon which is
associated with the nozzles will limit the amount of ink returning from the drop
generator into the reservoir.
