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.

Radiant and Convective Heating of Paper in Cassette
A copy sheet supply cassette is positioned in proximity to heat releasing
elements of a copier so that paper contained within the cassette is dried by the
In the example shown, copy sheet supply cassette 10 contains a stack of
copy paper 11 introduced through the open rear area 12. Stack 11 is pivoted by
floor plate 13 towards a picker roller or a picker roller is introduced through the
open front slot area 14 for individual sheet feeding into a mechanism (not
shown). The heat-generating elements in the particular example here shown
here a set of fuser rollers including heated hot roller 20, which engages backup
roller 21. Backup roller 21 has a scraper blade 22 arranged for removing toner,
sediment and the like for retention in sump 23.
The elements of the copier are arranged such that there is a relatively short
distance between the fuser rollers 20 and 21 to cassette 10 so that heat by
convection or radiation, as shown generally at 25, is directed towards the
opening 14 of cassette 10. Thus, a chimney effect is obtained by some of the
heated air passing upwardly over copy sheets 11 through the entry way 14 and
out the exit 12. Additional buffering elements can be employed, if desired, to
further direct the heat convection and radiation, such as 25, into and through
cassette 10. This arrangement reduces paper wrinkling due to high humidity and
long idle times between copies in a high humidity en...
