    Impact of EMF generated by Subsea HV Power Cables on the performance of FOCs

    I always thought that it was D.C. at H.V.? The one from Norway to N.E. England certainly is: https://en.m.wikipedia.org/wiki/North_Sea_Link

    Heathrow power outage

    I'm surprised that transformer cooling oil is flammable. Is this common practice worldwide? There doesn't seem to be many re-routes to Newcastle (UK) airport. I would have expected more as there's a good(ish) rail link to London, and a rail link from the airport to train station every few minutes.

    THERMOPLASTIC COMPONENT PART CRACK

    Have a look at transparent amorphous Nylon 12. It's used for bowls for air line oil seperators etc. Doesn't suffer from ESC. Excellent chemical resistance. I'm not sure if Facebook has ever caused the lame to walk, but it has surely caused the dumb to speak.

    Tolerance differences between polypropylene and nylon 6,6

    Polypropylene is a semi-crystalline material. Tolerance tables look ok. Sort of generalised. What is the variation in size which would be acceptable? (As a %age) Have you checked the comparative material costs of your choices? Nylon 12 has low water absorption and outstanding chemical...

    Wire forming machine design issue

    On a bigger scale, I have seen a cnc pipe bender in operation. The pipe was held in a collet chuck and indexed forward to a former and a hydraulic ram put bend #1. Pipe rotated and indexed forward for bend #2 and so on. There was also a saw station to cut the tube at whatever angle required...

    I-195 Bridge Closure, R.I.

    Our local council have just started repairs on a local bridge. (Northumberland, UK). It's only 400 yrs old this year. https://www.northumberland.gov.uk/News/2024/Jan/Repairs-for-Berwick-bridge-starting-ahead-of-400th.aspx Politicians like to panic, they need activity. It is their substitute...

    Iceland volcanic eruption

    I always understood that sulphur dioxide (as emitted) from volcanic eruptions caused global cooling? Politicians like to panic, they need activity. It is their substitute for achievement.
