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.
Print magnets are mounted on closer centers, as shown in Fig. 1, rather than with normal spacing, as in Fig. 2. The dimensions given in these figures are illustrative only.

Shared Winding Magnets
Print magnets are mounted on closer centers, as shown in Fig. 1, rather
than with normal spacing, as in Fig. 2. The dimensions given in these figures
are illustrative only.
In Fig. 1, two pistons share the same bobbins and windings. As a result, the
spacing for each pair of coils is .300" rather than .400" even though the number
of windings remains the same.
Referring to Figs. 3a and 3b, the selective operation of each piston is
accomplished in the following manner. Adjacent permanent magnet pistons will
have opposite polarities. With current flowing in the direction shown in Fig. 3a,
the "N" piston is driven forward and the "S" piston remains stationary. With the
current flowing in the opposite direction, as shown in Fig. 3b, the "S" piston
moves and the "N" piston remains stationary.
