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.

Locking Device for Inserts in Tubing
This article relates generally to devices for mechanically connecting
structural elements and more particularly to a mechanism for locking tubular
Fig. 1 shows the elements of a locking mechanism 1 which
includes a pressure pad 2, a clamp 3 and a screw 4. Pressure pad 2
has a ramplike surface 5 against which the rounded bottom of clamp 3
is forced as screw 4 is tightened in a threaded hole 6 in clamp 3.
The latter is normally mounted on a fixed surface and engages hole 6
in clamp 3 via a slot 7 in pad 2.
Figs. 2A and 2B show a front and side view, respectively, of mechanism 1
when it is used to clamp two tubular elements together. In these figures,
mechanism 1 is used to hold a channel 8 within a tubular element 9. The bottom
of pressure pad 2 extends through a hole 10 in channel 5 and is forced against a
wall 11 of element 9 when the bottom of clamp 3 is drawn against surface 5 of
pressure pad 2 by turning screw 4 in hole 6.
As screw 4 is turned, the flat upper portion 12 of clamp 3 is forced against an
upper wall 13 of channel 8 to provide a pressure point against an adjacent wall of
element 9. When screw 4 is tightened down, a flange 14 is forced against an
adjacent outer wall of element 9, providing another pressure point.
Mechanism 1 is placed in channel 8 assembled and, when channel 8 is
inserted into element 9, the depth of a slot 15 in element 9 determines the final
positioning of mechanism 1. Loosen...
