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.

Component Dispenser And Staging Apparatus
Electronic components are individually dispensed from a magazine and
oriented for pickup by a vacuum head.
Pressure feeding of components through a magazine for direct pickup often
results in jamming and misalignment, and requires switches and sensors to
insure reliable operation.
In Figs. 1 and 2, a magazine 1 is vertically oriented and contains a number of
components 2. Components 2 are to be used for populating a circuit board.
Components 2 are fed under the influence of gravity toward an apparatus 3.
Apparatus 3 dispenses a new component 2 from magazine 1 each time a head 4
picks up a previously dispensed component 5. Upon the lowering of head 4 for
pickup of component 5, a leading edge 6 contacts a gate 7 and causes
downward rotation thereof about a shaft 8. During the lowering of head 4,
component 5 will be attracted by the vacuum applied through a channel 9.
Component 5 can then be transported to a circuit board.
Connected to shaft 8 is a finger 10 which is rotated to the left upon downward
rotation of gate 7. Leftward rotation of finger 10 results in the bottom one of
components 2 being translated to the left for gravity feed down a ramped channel
11 and abutment against a stop 12.
