Another submission reduced to virtual gibberish. Here's what I wrote:-
Hi Patrick,
Once more SEM has landed on the door mat, plenty to read as usual but I found the ID&ASST piece from Nick Rowland particularly interesting and hope I can add some information
1) Lowne atmospheric engine. I attach a picture and description of a similar engine which is reproduced in hot air engine helpline advisor Bob Sier's book 'Hot air caloric and stirling engines'. It's not easy to see the burner, but is does look like a fairly simple cyclindrical 'bunsen' type much as Nick has already constructed. I guess you'd need to contact Bob for permission to use the material in SEM. 2) Hardy and Padmore 'style 1'. I attach a picture of what I believe to be such an engine taken at this year's 1000 engine rally. Note that it is built to Southall's, rather than Southwell's, patent and is certainly rather different to Nick's charming model. 3) 'Leek' engine. It has often been observed that no two of these engines are alike as most were amateur built using, as I believe Charles Hudson put it, "the parts of the moment". So it is quite in order to use any carburettor which looks the part. I am particularly fascinated by what I take to be the governor; presumably as it rotates the two pieces of chain fly out into a catenary curve which tightens with increasing speed - ingenious!Apart from the general mangling, they managed to transcribe 'catenary' as 'centenery' (corrected my typo on the word cylindrical though!). Sometimes I wonder if I can really be bothered submitting stuff any longer :-(
