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.
A surface mounted automatic guided vehicle guide path is described which
avoids cutting a trench in a concrete floor.
The guide path is constructed as follows:
1. The floor guide path area is cleaned with a scrubbing
2. The path is accurately marked on the floor with chalk.
The chalk marked floor is then sprayed with clear lacquer, to retain
the chalked lines until physical abrasion. 3. The guide path is
abraded two inches on each side of the chalk line with a vibratory
tool to roughen the surface of the floor. The chalk lines are
removed by abrasion during this step.
4. The floor is cleaned with a dry vacuum.
5. A first coat of urethane epoxy resin is applied to the
abraded path, in the direction of the path. The resin may be colored
to identify the guide path.
6. A glass cloth tape, approximately two inches wide, is
applied to the tacky first coat.
7. A second urethane epoxy resin coat is applied to the glass
cloth tape, until the cloth is impregnated.
8. A flat, braided copper conductor is applied on the tacky
second coat. A second redundant conductor can be applied if desired.
If multiple guide path conductors are required, they are positioned
beside one another, taking care to leave one-quarter inch separation
9. If crossing conductors are required, a two-inch wide piece
of glass cloth tape is laid across the first conductor, and another
urethane epoxy resin coat is applied to t...
