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.

Rapid Decompression Regulator
Figs. 1 and 2 show a regulator which decompresses a compressed system,
such as an ink jet printing system, at a very high speed without overshooting
The rapid decompression regulator comprises a cylinder or tank 10 in which
a ball 12 is placed. The cylinder is fitted with ingressed and egressed pipes 14
and 16, respectively. In operation, the compressed system (not shown) is
coupled to one of the pipes. For description purposes, assume that the system is
coupled to pipe 14. With the ball at the bottom of the cylinder, fluid motion
around the ball is restricted. As the volume of fluid increases in pipe 14, the ball
is forced to rise from the bottom to the top of the cylinder. As the ball reaches
the top, it is stopped by the top of the cylinder or adjustable screw 18. At this
point, the ball acts as a restricter to the movement of fluid in the cylinder. After
ambient pressure is reached, the ball is forced by gravity to return to its original
position. The showing in Fig. 1 represents a fixed version, whereas Fig. 2
represents an adjustable version wherein screw 18 is used for adjusting the level
to which the ball may rise.
