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.

Disclosed are a pack of electronic circuit cards, preferably printed circuits, in

It is known from the art for a pack of circuit cards with contact bars on one
edge to be plugged in parallel into a connector board. The surface of the
connector board is provided with parallel contact bars. The connector board
generally comprises printed circuits connecting the circuit cards to each other
and the outside. For increasing the number of connectors, individual flat cables
are linked by connectors with the circuit cards opposite the connector board.
Also known are packs of circuit cards provided with contact tags on two or
three edges, which are inserted into a housing with so-called ZIF (zero insertion
force) contacts. In the inserted state, the ZIF contacts are closed by a cam.
The arrangement shown in the exploded view permits circuit cards 1, 2 to be
provided with contacts on opposite edges and for these to be connected to
sliding contacts in two connector boards 3, 4. This arrangement permits circuit
cards to be readily exchanged also by customers. The two connector boards 3,
4 are moved by means of a lever mechanism against the contacts of circuit cards
1, 2, so that all connections are established at the same time.
For moving contact boards 3, 4, they are connected to U-bars 5 in which
camshafts 6 are arranged. Camshafts 6 are supported on pins 7 in the housi...
