We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Fig. 11 JOINING TWO-CORE CABLE A Cut away half the outer cover as shown, and then cut the inner wires so that one is longer than the other. Remove as little of the inner insulation as possible. B Splice and solder the wires together, but be careful to match the colours of the inner insulation. Test the joins by pulling before taping them. C If the outer covering has been correctly cut it should now be possible to fit the ends together without any part of the join exposed. It must now be covered by insulation tape, and bound as tightly as possible. Next roll the join between your hands to make the tape stick properly. The finished join may be further protected by a coating of paint, especially if it is to be used out of doors. 55
