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.

Vacuum Chamber Bell Jar with Built-in Cooling Body
The vacuum chamber, as shown in Fig. 1, depicts a way of
forming a chamber - bell jar with uniquely built-in cooling capacity.
The arrangement provides simple and efficient cooling.
The chamber body is made from rectangular tubing, as shown at 1 in Fig. 1.
The tubing is helix-coiled into a circular chamber body, although other chamber
shapes are possible. This can be seen from the top view in Fig. 2. This helix
coiled body serves a dual purpose. It becomes the physical body of the
chamber-bell jar, and the helix becomes a natural channel for water or other
fluids to circulate freely within the chamber wall, thus providing cooling capacity
with superior efficiency. Flanges 11 and 13 permit coupling to other apparatus.
An inlet and outlet for cooling fluid is provided at 5 and 7. In addition, a
viewing port may be provided, as shown at 9. Fig. 3 shows an enlarged partial
section of the viewing port. As can be seen, the viewing port is positioned such
that only a portion of tubing is removed, thereby permitting fluid to pass from the
inlet port 5 to outlet port 7. In this manner, the entire chamber is cooled, including
the viewing ports. Cooling may be variably controlled by adjusting the orifice of
the outlet port.
