History
The 'Igniscope' electronic ignition tester was produced by English Electric during the 1940s, originally as 'type UED' for military use during World War II. The post-war version, 'type ZWA' electronic ignition tester, was advertised as "the first of its kind, employing an entirely new technique".
The Igniscope used a cathode ray tube, giving an entirely visual method of diagnosis. It was invented by D. Napier & Son Ltd., a subsidiary of English Electric, and British Patents 495478, 495547 and 563502 applied. The Igniscope was capable of diagnosing latent and actual faults in both coil and magneto ignition systems, including poor battery supply bonding, points and condenser problems, distributor failure and spark plug gap. One feature was a "loading" control which made latent faults more visible.
The UED manual includes the spark plug firing order of the tanks and cars used by the British armed forces

Famous quotes containing the word history:
“... the history of the race, from infancy through its stages of barbarism, heathenism, civilization, and Christianity, is a process of suffering, as the lower principles of humanity are gradually subjected to the higher.”
—Catherine E. Beecher (1800–1878)
“... in a history of spiritual rupture, a social compact built on fantasy and collective secrets, poetry becomes more necessary than ever: it keeps the underground aquifers flowing; it is the liquid voice that can wear through stone.”
—Adrienne Rich (b. 1929)
“To summarize the contentions of this paper then. Firstly, the phrase ‘the meaning of a word’ is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, ‘being a part of the meaning of’ and ‘having the same meaning.’ On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.”
—J.L. (John Langshaw)
