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.

Sheet Feeding Apparatus
This apparatus provides for sheet handling from a cartridge without the need
for a stack elevator.
In the figure, a hopper 1 containing a stack of sheets is shown. The side wall
2 of hopper 1 has an opening to accommodate a paper feed wheel 3 which is
similar in structure to that shown in the IBM Technical Disclosure Bulletin 20,
2933 (January 1978). Paper feed wheel 3 includes a hub 4 about which a
plurality of shafts 5 are rigidly attached. Resilient rollers 6 are free to rotate
about shafts 5. Paper feed wheel 3 is connected to a motor (not shown) which is
mounted in housing 7. The feed wheel assembly is slidingly connected to shafts
8 so that feed wheel 3 can floatingly engage the top of the stack even as the
stack is depleted. Thus, the need for a sheet elevator is eliminated.
During a feed operation, rollers 6 contact the stack only in the arc indicated
by arrow 9, imparting translational movement to the top sheet. As a sheet is fed,
it cams over slanted end wall 10. Exit rollers or the like are positioned to the right
of the end wall 10.
