Cooking With Electricity.

Zoomup
1. Locate your old M.E.M. switch fuse.


2. Open the door to check that the working parts are dry and need grease.


3. Apply spray lubricant generously to handle and mechanical moving parts.


4. Close door.


5. Operate switch handle to distribute lubricant and help it work in.


6. Observe smoke issuing from enclosure.


7. Panic.


8. Realise that a spark must have set fire to the lubricant or propellant.


9. Realize that a fire extinguisher is not to hand.


10. Panic again.


11. Fan flames with rag in effort to snuff them out.


12. Remove burning switch fuse door and throw it to a safer place.


13. Allow everything to cool then reassemble.


14. Read warning label on spray can lubricant with strong magnifying glass. Notice the words Highly Flammable in letters 0.25mm high.


15. That is how you flambe an M.E.M. switch fuse.

    Long, long ago, when the earth was green, unicorns roamed and health and safety were just words in the dictionary.


    As a 17 year old RN electronics apprentice our lab had (amongst others) 220V DC at terminals on the benches (what was that about health and safety). In those days experiments using bottles (valves or vacuum tubes) were very much part of the training, so having 220V DC on the bench was very handy. 


    A couple of the guys decided that the 220 DC would be a good energy source for cooking a sausage. Said sausage was duly connected to the supply using a couple of bits of copper foil, one at each end. After a few minutes the smell of "cooking" sausage along with satisfactory sizzling noises permeated the lab. The sausage looked and smelled cooked, however due to the fact that it had gone green along half its length (probably due to copper migrating from the electrodes) nobody would actually try eating it. Experiment deemed a failure :( 


    Slightly later in life we were training in one of the Radar test labs testing magnetrons. Said magnetrons obviously needed a load and in the absence of a microwave dummy load a simple matching horn was attached to the output and a warning sign installed. Broadcasting at 25kW PEP out of the lab window was considered OK. Placing a pasty in front of the horn did indeed result in the pasty getting warm (the average power was only a few hundred watts). Apparently at one point someone did actually walk in front of the horn whilst the magnetron was operating and suffered no ill effects, it didn't even fix his stammer.
