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.

Print Head for High Resolution Electrographic Printers
For high-speed, high-quality printing, paper 3 is pressed by flexible platen 4
(fine-pored foam rubber) against electrodes 2 of print head 1 (Fig. 1). Flexible
platen 4 rests on solid platen 5.
To ensure that the print conditions are the same for all electrodes, print head
surface 6 is approximately circularly shaped, thus compensating for the
deformation of the paper on flexible platen 4.
To avoid the accumulation of print debris (metal oxide and resist particles)
between the print head surface and the paper, the print head surface, in
comparison with the surface marked by broken lines, is rounded off on both sides
of the electrodes in the direction of print (Fig. 2).
