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.

Ink Jet Printer/Copier

An ink jet printing mechanism 11, including an ink nozzle which is
translatable to form character images, effects printing on drum 13 which is
advanced in a line by line fashion to create a facsimile of a page of information.
After the ink is applied to the drum 13, it is dried by heater 15. The ink drying
station is required because the nonporous conductive drum surface will not allow
ink to dry by absorption. The ink contains a water-soluble polymer having low
conductivity when dry, thereby allowing the ink image to hold an electrostatic
Once a complete document image has been created and dried, it is thereafter
advanced past the charge corona station 17 and thence past the developer 19.
Toner particles are deposited upon charged inked characters at the developer
station 19 and subsequently transferred at transfer station 21 to copy paper 23.
The toner is then fused in a conventional manner by fuser 25. Excess toner is
cleaned from the drum at cleaning station 27, and the image is thereafter
recharged and retoned to create multiple copies.
Once the requisite number of copies have been produced, a solvent cleaning
station 29 is activated to remove the ink image from the drum 13. Both binary
