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.

Transformer Card Support
Disclosed is a description of a self-adjustable structure that adjusts to having
different lengths of printed circuit boards due to tolerance build up of the board
itself or of its mounting hardware.
The free state of the structure is of a curved form having snap in tenons at
the extreme ends of the stucture. There are individual guides or tenons projecting
off of the curved surface to supply support and guidance for the expansion card
or board. The guides are individually spaced to allow free movement of the
curved structure. These guides are beveled on either end as well as on the top.
This is to assist guidance of the card/board into the structure from the front or
from either end. The self adjustment of the structure is supported by having one
of the tenons snapped into a elongated slot. As the card/board contacts the
curved surface the structure by way of the elongated slot flattens out. Apply
pressure to the card/board and absorbing any tolerances accumulated in
construction of the card/board or its mounting hardware. Since the card/board is
under tension, the arrangement adds acoustic support. Allowing minimum
vibration resulting in no damage to components and/board. This structure is
applicable to all known printed circuit boards and expansion cards presently
