Dr Terry, I think you've been taking provocation lessons from Castellan....
None of this has anything to do with forward facing illumination devices, or Sandmans, (or is that Sandmen?) but fun nonetheless.
I reckon it's a lamp. Thomas Edison invented it, and that's what he called it. Good enough for me.
Nope, they are not both dynamos. An alternator, in our world is, in the case of Bosch, a 3 phase star wound rotating machine with a controlled DC field which produces AC voltage, subsequently rectified to DC with a 6 pulse full wave diode bridge.
The only brushes used are for the passage of DC control current to the field via sliprings for voltage regulation. There is no commutator. The brushes do not carry the output current of the alternator.
In the case of Lucas, as above except that the stator winding is delta connected.
Generators, as loved by EH and earlier aficionados have a segmented commutator, brushes which carry full load current and produce DC voltage directly, without further rectification. They meet the definition of a dynamo.
I agree, inflammable makes no sense, but it is the older of the two. One look at the back of an LPG tanker confirms the current convention.
I've used the same strategy with the periodic table, but the elements Americium and Californium are usually the most difficult for your average Yank to argue with. They named them, after all.
The word stickybeak seems to dumbfound the average yank, but I do like the shifter story. What do they call them - "crescent wrench" isn't it?
There's a fairly long list of aeroplanes that have crashed after running out of fuel because their brilliant US gallon has only 3.78 litres instead of 4.55 litres, even though that issue is usually the subject of a question in pilot exams.
And as for exchanging drawings with metric dimensions on them with US colleagues, all I can say is thank goodness for CAD, where you can switch between units easily.
American English? No such thing exists.
