blue streak 1 You have to wonder if Edison had not put his eggs in the DC current basket how much he could have dominated the electric industry ?

Curiously, while his technology wasn't adopted, his name was - Consolidated Edison, Detroit Edison....

Had he adopted AC before he electrified New York City, life would have been less complicated for the residents--in time, parts of the city used AC while other parts used DC. Any electrical equipment that had a transformer in it could not work on DC. The radios that could work on both AC and DC were quite popular. The "all-American"tube complement was quite popular; the heaters of the tubes were wired in series, so no transformer was necessary, and there was a rectifier so AC could be used. There were, usually, three tubes with 12.6 volt heaters, one with a 35 volt heater, and one with a 50 volt heater. The transformer for use on AC only had three secondaries: 6.3, 5, and 350-0-350 (full wave rectification) volts, usually.

Johnny, you bring back memories-- I worked on many a five-tube AC/DC radio years ago. Those things could be a dangerous shock hazard. Depending on which way you plugged them in, the whole chassis could be hot or neutral.

In the 50's, I had little money but wanted a high fidelity system. Bought a Heathkit AM/FM tuner and since I couldn't afford the Amplifier, modified a Monarch table radio (with a hot chasis) putting a switch between its tuner and amp section and bought a 1:1 isolation transformer to keep from killing myself. This gave me FM music. I didn't have to buy records. Then when I gained addition resources, I bought an Heathkit amp and one speaker. Slowly I acquired my Stereo system.
When I moved to Chicago in 61, ComEd still served a lot of buildings in the downtown area with DC systems. They had about a dozen rotary converter sations served by a 25 cycle 9 KV underground system providing 110/220V DC. There were buildings with IBM electric typewriters with DC motors. The elevators used DC motors. Over the next ten or fifteen years the DC network was retired.
Isn't it amazing how long it is taking to eliminate the last vestiges of 25 HZ ? Still a few legacy industries using 25 HZ. Then there is Amtrak !!!
Interesting. I was looking through the pages of a 1930's era Lionel catalog (reprint) and lo and behold Lionel sold a DC to AC conversion unit for those parts of the country using DC current. I had no idea there were still some areas that were DC as late as the 1960's.

And now, back to the humor.

Doctor Jones likes to stop at a bar after work and enjoy an almond daiquiri. One day, Dick the bartender runs out of almonds and uses hickory nuts instead. The doctor takes a sip and says, “Is this an almond daiquiri, Dick?” And Dick says, “It’s a hickory daiquiri, Doc.”

The New Haven ( MNRR ) converted some years ago to 12.5Kv 60 Hz during one summer's lull over what was about a 2 week (?) period. Had quite a large amount of diesel trains during that period. The CAT conversion to constant tension is still proceeding with scheduled completion sometime next spring As well the Amtra New Haven Hell Gate line from New Rochelle to Gate interlocking ( near SSY ) was converted about 2 (?) years ago to that same power along with constant tension CAT..

Guy walks into a restaurant and says "Do you serve crabs?" The waiter says, "This is a gas station, we don't serve food."

Wait, I got more!

The Mechanic's Lament

Years ago I would go to a transmission parts house from time to time. On one visit, one of the counter guys said they started each day with a prayer thanking God for the Hydramatic Division of GM.
And then there is this tale!
While I was working as a store Santa, a boy asked me for an electric train set. “If you get your train,” I told him, “your dad is going to want to play with it too. Is that all right?”
The boy became very quiet. So, moving the conversation along, I asked, “What else would you like Santa to bring you?”
He promptly replied, “Another train.”
My friend announced that she had started a diet to lose some pounds she had put on recently.
“Good!” I exclaimed. “I’m ready to start a diet too. We can be dieting buddies and help each other out. When I feel the urge to drive out and get a burger and fries, I’ll call you first.”
“Great!” she replied. “I’ll ride with you.”
I was having a drink at a local restaurant with my friend Justin when he spotted an attractive woman sitting at the bar. After an hour of gathering his courage, he approached her and asked, "Would you mind if I chatted with you for a while?"
She responded by yelling at the top of her lungs, "No, I won’t come over to your place tonight!"
With everyone in the restaurant staring, Justin crept back to our table, puzzled and humiliated.
A few minutes later, the woman walked over to us and apologized.
"I’m sorry if I embarrassed you," she said, "but I’m a graduate student in psychology and I’m studying human reaction to embarrassing situations."
At the top of his lungs Justin responded, "What do you mean, two hundred dollars?"
Sam, I'm a little skeptical of that post about the gunpowder on one's oatmeal. Not sure I could do it, unless I had an offer I couldn't re-fuse.However, I probably wouldn't mind if my pockets were stuffed with M-80s and other assorted devices before I entered the crematorium.And all of that, of course, would be after a closed-casket ceremony in which the organist had been instructed to play "Pop Goes the Weasel" at the appropriate time.

Too Funny, [ ROFL, etc.etc. ] Carl!
It is really good to see that the doctors have not effected your wry sense of humor; while they were 'practicing' on you.

There have been a few reports in the fire trade press involving folks who provided just a little bit too much fuel at the crematorium, requiring a fire department response....
Had this sent to me recently;
Here is a guy reporting to the police that his wife is missing:
Husband: My wife is missing. She went shopping yesterday and has not come home...
Sergeant: What is her height?
Husband: Gee, I'm not sure. A little over five-feet tall.
Sergeant: Weight?
Husband: Don't know. Not slim, not really fat. Sergeant: Color of eyes?
Husband: Sort of brown I think. Never really noticed.
Sergeant: Color of hair?
Husband: Changes a couple times a year. Maybe dark brown now. I can’t remember.
Sergeant: What was she wearing?
Husband: Could have been pants, or maybe a skirt or shorts. I don't know exactly.
Sergeant: What kind of car did she go in?
Husband: She went in my truck.
Sergeant: What kind of truck was it?
Husband: A 2015 Ford F150 King Ranch 4X4 with eco-boost 5.0L V8 engine special ordered with manual transmission and climate controlled air conditioning. It has a custom matching white cover for the bed, which has a matching aftermarket bed liner. Custom leather 6-way seats and "Bubba" floor mats. Trail-ring package with gold hitch and special wiring hook-ups. DVD with full GPS navigation, satellite radio receiver, 23-channel CB radio, six cup holders, a USB port, and four power outlets. I added special alloy wheels and off-road Michelins. It has custom running boards and indirect wheel well lighting.........
At this point the husband started choking up.. . . .
Sergeant: Don't worry buddy. We'll find your truck.
Wife says she will probably vote for the candidate who has the best hairdo the night before the election !!!
All day I face the barren waste without the taste of liverwurst (except today).
