  1. The most brilliant minds ever, never had university educations that moulded them into their way of thinking, two come to mind, Einstein and Tesla, when it comes to engineering and science NEVER scoff at any idea.

    We were taught "laws of physics" according to our discipline, mine being electricity and electronics, my mind was moulded to fit their teachings, including text books, learn to think outside the "box" and ANYTHING is possible.

    Had the inventors of many things thought it was like two unicorns, we'd still be in the dark ages. "Iron ships", heavier than air flight, flat screen monitors, semi conductors, chips holding millions of transistors" etc being perfect examples of what I said.

  2. I forget what country it was, but regen battery charging was used on one of their cities buses. The buses had a heavy flywheel that assisted in "storing" (kinetic) energy as well, from recollection it was a partial success, as the bus stopped, a clutch disconnected the motor and the flywheel kept a small generator running charging the batteries.

    Bit cumbersome, but at least someone was trying.

     

    As far as perpetual motion is concerned, I think you will find it is possible. I saw a video of a feller who had a motor generator set where initial energy was used to start the motor, which was then fed by the generator. He'd worked out how to gain more energy out than used in generation. I know, but all the laws of physics are theories and theories change when proven ones are dismissed.

    He couldn't get anyone to look into his test set up, found an Indian electrical engineer at an Indian nuclear power station to look into it and explain WHY it worked. The engineer looks at a schematic he'd enclosed and said IMPOSSIBLE. After some pleas, he built a test set up according to the engineering drawings and put it to the test and was floored! He stated, I have no explanation as to "how" it works, BUT it does! It defies all the known laws of physics...

    I doubt we will hear too much of it as it presents a danger to commercial annual profits.

  3. I dug my old book out, "The Telestatic" system, perusing it took me back to other relay based systems of the 1970's that might have been modified to the Telestatic system.

    When I was at Boulby, the auto skipping plant could probably have been wired with PLC's.

    The conveyors were controlled by Huwood Mk1A system, being flameproof, would have been an obstacle to install with PLC's, but remembering the circuitry, would have been an easy changeover.

  4. That's the babies Phil, each type was colour coded, there were two sizes, one about 2 inches wide, then another about 4 inches wide, they had a light on one corner at the top. Somewhere I still have the Telemechanique book.

    By today's standards, they were crude, and to understand how they worked, it was essential to understand electronics, but, they worked!

  5. You'd have to be maintaining machinery to come across PLC's Dave. Closest I've been to PLC's was in the early 70's when I worked at Beeston Boiler Company as a maintenance elec on their automatic foundry plant. Everything was controlled by plug in electronic modules made a by a French company, basically the forerunner of PLC's. First thing every morning, they had to be set up before the plant started operating, basic difference is PLC's use flash memory, and the ones we used had magnetic core memories, much like the early computers used.

  6. The problem with technical trades was keeping up with technology, we did get refresher courses at the NCB training centres, but in outside mining companies, it was your responsibility to keep up with technology.

    I'd be stuck on PLC's, as I never encountered them, but it seems from what I read they are appearing in the big several million dollar coal cutting machines these days, with radio control too and telemetry on the machines diagnostics.

    I was lucky in that electronics was entering the mining industry during my apprenticeship, so I was prepared.

  7. Part and parcel of fault finding, sometimes you have to swap out something to get to the bottom of things. Back when I started my apprenticeship as a colliery electrician, control gear and starters were pretty simple, when I retired you needed a degree in rocket science...LOL Belt starter control units at Boulby were pretty complicated, and the switchgear had loads of electronics in them, so much that when we had an intermittent fault occur, it was almost impossible to locate until it gave us a clue.

    The shearers I worked on in Oz on the coal face were highly sophisticated machines, both electrically and mechanically, as were the self advancing roof supports which were controlled by micro processors.

    Auto's these days are beyond the back yard mechanics, the engine has so many sensors you need expensive scanners to locate a problem.

     

  8. Technicians these days, they tend to specialize, like engine techs, transmission techs, auto electric techs. Mechanics were always known as fitters in my day. Diesel fitters, auto fitters. Even the mechanics I worked alongside "dahn pit" were called fitters. I was classified as an Electrical Fitter in Oz.

  9. When I worked at Boulby Mine in Yorkshire, my labourer used to give me a lift to and from work. He'd beat me through the showers as I'd have to hand over my reports etc at the maintenance window. I got outside to his car, and he told me there was an identical car to his, his door key fit the door, but the ignition key wouldn't turn, it took him a couple of minutes before he realized he wasn't in his car.

  10. All the Ford "F" series pickups used to have "hub locks" to engage the wheels in 4WD at one time, now it's done through the transfer case. The beauty of hub locks is you're not driving the front wheel axle and reducing drag when in 2WD.

     

    The Suburu station wagon I had in Oz was manual transmission, had 4WD Hi and Low range, selected by a second gear shift, could be done safely "on the fly" where as on my Chevy Silverado, I have to stop, select neutral and turn a switch to either 4WD or 4WD lo and wait until the light goes from flashing to steady.

  11. Dave, that takes me back to when I rewired the house we bought in Australia, stripped to my shorts in the roof space running cables out, 100 plus outside, tin roof too!!

    Mind, I worked at Boulby for nearly five years, when I worked in a district the coolest spot was 90F and that was our snap cabin, try 110 plus in the faces!! Mind the only cables I pulled down there were heavy trailing cables that few the machines.

    I planned my days on this house when I built it, ran all the cables out prior to gyprocking the ceilings.

  12. Thankfully it won't be us, too far south for snow that heavy, but there will be many people it affects, think of all the truckers trying to earn a crust and trying to get home for our Thanksgiving holiday to see their families, stuck at a truck stop for a few days.

     

  13. Reminds me of annual tests of feeder cables underground, having to do a continuity test of both conductors and earth, as well as an insulation test of all three phases between and to earth. Long job on a couple of miles of high voltage cable.

    As I always stated, the most important conductor is the earth conductor, one can live if we lost a phase, but lose the ground and it's deadly.

    Under M&Q Act, if a circuit tripped on earth leakage, we weren't allowed to close the breaker, a test with a megger was required to prove the circuit one way or another. Under NSW, CMR Act, we were allowed to close once and once only, if it held, we considered it was OK, trip again, then a full test of the circuit was required.

     

    Over this side of the pond, domestic outlets can be one of two types, quick connect and screw connect. In my opinion, the quick connects should be banned by law. The conductors are held in place by a spring contact, as they age the spring loses tension. I'd hazard a guess 8/10 house fires are caused by those stupid outlets.

  14. I don't think any 3 speed autos are made anymore, as I said previously, mines a six speed, wife's old truck was five speed, not sure what her Toyota Rav4 has.

    When we first came over her in 89, we bought a Subaru station wagon as we found them perfect in Oz. This one had A/C, from a standing hill start with the A/C running, it struggled, and that was a manual.

    I'd imagine it would have lost some more power had it been an auto, with the hydraulic pump in the transmission.
