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. I did a class on PLCs run by an electrical wholesaler I used. It was interesting but I never actually came across any in the wild so it was mostly a waste of time for me. Quote Link to post Share on other sites
Ayupmeducks 1,730 Posted December 2, 2019 Report Share Posted December 2, 2019 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.

philmayfield 6,187 Posted December 2, 2019 Report Share Posted December 2, 2019 The French PLC’s would probably have been Telemechanique. Those I was more familiar with were made by Siemens. It was so long ago I have forgotten how to set them up! Quote Link to post Share on other sites
loppylugs 8,429 Posted December 2, 2019 Report Share Posted December 2, 2019 Yes. I did mostly residential and commercial so weren't to likely to run into them. Always beleived in learning as much as I can ya never know when it might come in. Last industrial I did was maintenance leccy at CCM in Toronto. Bit like working for Raleigh. They built bikes and ice skates. All their machinery used relay logic. I guess that makes me a Dinosaur. That was mid 70s. Edited to add. The plcs I learnt were Allen Bradley. I imagine they are all pretty similar. Quote Link to post Share on other sites
Ayupmeducks 1,730 Posted December 2, 2019 Report Share Posted December 2, 2019 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!

philmayfield 6,187 Posted December 2, 2019 Report Share Posted December 2, 2019 We had both Siemens and Telemech on process machinery. It's all in the dim and distant past now and long superseded. Quote Link to post Share on other sites
Ayupmeducks 1,730 Posted December 2, 2019 Report Share Posted December 2, 2019 I worked with it on BBC's BMD plant Phil. I did a "Google" a few minutes back, seems Telemechanique is now owned by a British company. Quote Link to post Share on other sites

Ayupmeducks 1,730 Posted December 2, 2019 Report Share Posted December 2, 2019 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.

MargieH 7,613 Posted December 4, 2019 Report Share Posted December 4, 2019 Went to a 4 hour refresher First Aid Course today and it was led by an excellent trainer. My dummy didn't breathe despite my best efforts but it was discovered he had a slightly twisted tube going to his 'lungs' so he had to have the front of his chest lifted off to fix it.....! We all hummed 'Staying alive' as we pumped their chests and none of the dummies died! We had fun being rolled into the recovery position and I didn't hear anyone pass wind in the process. .... shame, that would have been a laugh (as long as it wasn't me!) We acted out various scenarios - love role play - and even learned something new .... . A technique which allowed a person with possible spinal injuries to be rolled over if their life was in real danger. Of course this can be risky and there is the moral / ethical question of whether a person would prefer to be dead or possibly paralysed... a big question. We had lots of personal discussions about that.... Enjoyed the day, anyway Quote Link to post Share on other sites

Stavertongirl 1,719 Posted December 14, 2019 Report Share Posted December 14, 2019 Having waited in for 2 days for a delivery by Hermes which was supposedly sent on Tuesday I have now had an email from the seller saying they are unable to obtain the dog biscuits I ordered. Which begs the questions: 1) Why did they not tell me when I placed the order that the biscuits were not in stock? 2) How can you send something out for deliver when you don’t have it? 3) How can you bill me for something you haven’t got/sent out? I am now waiting for a refund and am not a happy bunny Quote Link to post Share on other sites
Jill Sparrow 10,310 Posted December 14, 2019 Report Share Posted December 14, 2019 It's called inefficiency, SG, and it's a national ailment. Quote Link to post Share on other sites
loppylugs 8,429 Posted December 14, 2019 Report Share Posted December 14, 2019 Not just inneffeciency. It shows a lack of integrity too. Very common these days. Quote Link to post Share on other sites
jonab 1,644 Posted December 14, 2019 Report Share Posted December 14, 2019 Similar inefficiency in France. I ordered an item 15 November on Amazon Prime for delivery next day. The only thing I received the next day was an email from a Chinese (in Chinglish) company saying my parcel would be received on the 9 December. I tried to cancel on the second day but was told it was too late as the item had already been despatched. That same day I went into Cannes and bought a similar item (it isn't of any particular value, it's a diamond knife hone/sharpener of value about €6) from a kitchen supply shop. Why didn't I go to the shop in the first place? Note: I've still not the received the item from China. Quote Link to post Share on other sites
Beekay 5,180 Posted December 14, 2019 Report Share Posted December 14, 2019 One of the reasons why I never buy online Jonab. Would be worrying all the time. At least in a shop you can look at what your buying. Quote Link to post Share on other sites
philmayfield 6,187 Posted December 14, 2019 Report Share Posted December 14, 2019 I’ve ordered twice from Amazon this week and in both cases they were delivered the next day. That’s not using ‘prime’ either. An update: It came next day but was wrongly delivered to a house down the lane. Someone’s just brought the package round! Spoke too soon about the efficiency. I’ve just ordered an electric shaver from Amazon which I spotted when tracking this package. £100 off! We shall see when this arrives. Quote Link to post Share on other sites
jonab 1,644 Posted December 14, 2019 Report Share Posted December 14, 2019 I don't usually have problems with online shopping but when it goes wrong, it goes very wrong. The problem with that order was that there was (is) wrong information on the website which has still not been corrected, despite my complaints. Quote Link to post Share on other sites
LizzieM 9,514 Posted December 14, 2019 Report Share Posted December 14, 2019 This morning l ordered online 4 wooden Venetian blinds, all different sizes and made to measure. They should be with us by Christmas ........ fingers crossed. We rarely order stuff online, really only lawn fertiliser and garden bird food but we’ve never had a problem with delivery. Actually I ordered a 20kg bag of sunflower hearts yesterday, the local birds are costing us over £100 a year, can we get any tax relief on it? 1 Quote Link to post Share on other sites
Stavertongirl 1,719 Posted December 14, 2019 Report Share Posted December 14, 2019 I have a squirrel who is still visiting my bird feeders or my neighbours (shouldn’t he be hibernating now?) for breakfast. I wondered why I was getting thru so much black sunflower seed. He is a bit of a pest but very ingenious, he hangs upside down on the bird feeder to get to the seed. I know I can get supposed squirrel proof feeders, but it doesn’t seem to bother the birds at all they are still coming after he has finished. Quote Link to post Share on other sites
Beekay 5,180 Posted December 14, 2019 Report Share Posted December 14, 2019 Read somewhere that squirrels don't hibernate. Especially if they find a regular supply of food. So keep up the good work SG., maybe vary his diet a bit. Quote Link to post Share on other sites
philmayfield 6,187 Posted December 14, 2019 Report Share Posted December 14, 2019 Grey squirrels don't hibernate but sleep more often during winter. We've got plenty round here. Quote Link to post Share on other sites
LizzieM 9,514 Posted December 14, 2019 Report Share Posted December 14, 2019 SG, a few months ago we found a young grey squirrel stuck INSIDE one of our ‘squirrel-proof’ bird feeders. Had to use wire-cutters to release him and he was a frightened, nasty little bugger while we were doing it. Fortunately we both wore very thick leather gardening gloves during the operation.

Stavertongirl 1,719 Posted December 14, 2019 Report Share Posted December 14, 2019 At present he is feasting on fat balls, black sunflower seeds, sunflower hearts plus what he gets from my neighbours bird table as well. One very well fed squirrel! Quote Link to post Share on other sites
Brew 5,423 Posted December 14, 2019 Report Share Posted December 14, 2019 We have three, agile little buggers aren't they? Its usually a race between them and a small flocks of pigeons to see which empties' the feeders first. Drives my neighbour crazy, says both are vermin but hey, my garden, my rules OK...
