Since the last article on 'Manual Labouring', I've now got to about page 20 - some transcription can be very tedious and the worst of all is reproducing the tables in MSWord.
The Optical Character Recognition's version of gobbledygook is particularly ripe when it comes to reading the lines across a page instead of extracting the text required from each table cell in turn; the result is something that would not look out of place with other output from an Enigma machine!
So I've given up that as a bad job and just inserted some original typewritten tables as scanned jpeg images.
For example - Fuels of various types:
(Historically this is an eye opener as I doubt that many of these fuels are available today due to the closure of the UK's mining industry).
Coals for a 200HP Sentinel:
(a) Groups 1 and 2 Bitumineous Coals are mainly free burning non-caking to slightly caking and swelling. Calorific values of between 13,500 – 14,670 B.T.U.s/lb.
(b) South Wales Groups specified are similar in burning but are less volatile and contain 92 – 94% carbon, requiring a somewhat more intense draught. Calorific values of between 15,250 – 15,200 B.T.U.s/lb.
Cokes for a 200HP Sentinel:
Manufactured Fuels for a 200HP Sentinel:
(a) With these patent fuels, it is usually found desirable to use a 1” or 7/8” blast nozzle in place of the standard 1.1/8” - 1¼” dia. nozzles.
(b) Standard fire bars are however, quite suitable.
(c) These fuels should not be stored in an open heap as they ‘weather’ and deteriorate in composition.
I'd be glad to hear from anyone who knows the present day equivalents of these fuels.
