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.

IPL Adaptor for a Tool Controller
The IPL (initial program load) adapter loads the initiating data into the
memory of the tool controller.
The IPL adapter consists of a bit counter 10 and two programmable read-only
memories (PROMs) 12 with sufficient control via control 14 to sequence the
counter which addresses the byte locations in the PROM 12.
In operation, the depression of the IPL switch causes the loading of the
required number of bytes into the tool controller (not shown) via the interface.
The first byte transferred instructs the tool controller to load the remaining
required bytes into the control memory starting with address 000C. The address
counter is incremented by a signal from the controller. After the required number
of bytes have been loaded in the memory of the controller, an end of operation
signal is given, after which the tool controller starts executing the inputted code,
starting at address 000C.
