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.

Fuser Release Evaluation
The toner-release property of an elastomeric material, intended for us in the
hot roll of a xerographic hot roll fuser, is tested.
The elastomeric material 10 to be tested is permanently bonded to a small
steel plate 11. The exposed surface 12 of material 10 is treated so as to model
exactly the fuser' s hot roll fusing surface. A thin, uniform layer of xerographic
toner powder is then applied to surface 12, and a strip of paper 13 is placed on
top of the toner layer. A weight is placed on the paper. The assembly is then
baked in an oven to simulate the time, temperature and pressure of the fuser's
The assembly is then removed from the oven, and steel plate 11 is placed in
jaws 14 of a force-measuring device, such as an INSTRONT Trademark of
The piece of paper 13 is doubled back upon itself, and is clamped in jaws 15.
The force necessary to peel paper 13 away from surface 12 is a measure of the
elastomer's release property. The lower the force, the better the release
This method can also be used to test various toners, as the paper grade and
elastomer are kept constant.
