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.

Door 2 is moved longitudinally (in direction A) through slot 4 in cover 1
thereby engaging its hinge pins 5 with cover 1 and pivotally (arrow 13) mounting
door 2 on cover 1.
Door 2 is moved in direction A through slot 4 in cover 1 until hinge pins 5 are
seated in pin receiving slots 6. Pins 5 thus pivotally mount door 2 with respect to
cover 1. This allows door 2 to swing in direction B to close opening 20 in cover 1.
Slots 6 are designed with snap fits for pins 5 which allow swinging of door 2 in
direction B in a free swinging mode. Door catch 9 on door 2 engages one end of
opening 10 and holds door 2 closed with a snap fit and also aligns door 2 in the
vertical direction. Springs 3 which are self-mounting on bosses 8 are placed over
bosses 8 with door 2 in closed position to provide a self-closing action and an
open detent position of door 2. Flange 7 seals door opening 10 for air control.
The door construction thus provides self-alignment, self-mounting and self-
sealing of door 2 and is low cost due to integration of parts and elimination of
