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.

Power Dissipation by Controlling Bubble Size of Liquid Coolant
Described herein is a coolant mixture adapted for use in chip cooling
systems, such as shown in U. S. Patent 3,741,292.
The coolant mixture is formulated from two different molecular weight
fluorocarbon liquids blended to produce a fixed boiling point comparable to that
of a single molecular weight species.
By mixing a fluorocarbon such as PP(3) (available from the Imperial Smelting
Company, Ltd.), having a molecular weight of 400 and a boiling point of 102
Degrees C, with a fluorocarbon such as FC-88 (available from the Minnesota
Mining and Manufacturing Company), having molecular weight of 288 and a
boiling point of 29 Degrees C, in the ratio of 39 v% PP(3) - 61 v% FC-88, a mix
was obtained with a boiling point of 56 Degrees C, which is substantially the
same as the commercially available fluorocarbon FC-86 (molecular weight 336).
