  1. Killer 6AM flight to Vegas, but just saw an awesome UK v. UNC classic with my man @falkon, his wife, and another buddy at the new T-Mobile Arena in the City Center. Lawry's Prime Rib next on the agenda! Oh, and slab bacon this morning at the Cosmo buffet in honor of you, @Grahame.

  2. Dr. Henry Heimlich maneuvered to age 96. 2016 decided that was enough. RIP to a real lifesaver.

  3. That was interesting. For seven years in the '90's I ran engineering at Oxford Instruments, and apart from some outrageously complicated superconducting magnets, we pretty much had the world market in dilution refrigerators. These are the leaping-off point for many techniques to get even colder, using processes like adiabatic demagnetization. Anyhow, the dilution fridge works by a really strange quantum mechanical effect using a mixture of regular helium 4 and a lighter isotope of helium 3. As with all these cooling processes (brought out in the video) it is multi-stage using a series of heat exchangers until at the bottom of the machine is a mixing chamber less than the size of an ice hockey puck. In this the helium 4 becomes a superfluid and sits at the bottom, and helium 3 floats on top and has the viscosity of corn oil. The hotter atoms of helium 4 diffuse upwards into the helium 3 (no viscosity, remember), and a truly impressive pump attached to the mixing chamber sucks these hotter helium 4 atoms out. That shifts the equilibrium point, and the next hottest helium 4 diffuses upwards, etc etc. We designed and shipped products using this process to labs around the world - about 1 per week - which produced a base temperature somewhere between 1 and 3 milli-Kelvin. A long way above pico-Kelvin sure. But the race for ever colder temperatures all starts off with a dilution fridge - other than the Bose-Einstein crew, which use a different cooling process altogether. Anyhow, here is the business end of a dilution fridge. The thing at the bottom is the mixing chamber, the disc-like things are a series of counter-flow heat exchangers filled with sintered silver, and the copper coil has a capillary inside and is the next highest temperature. Not shown is something above all that called the "1K pot" which is what is says on the tin - so everything in that image sits at less than 1 Kelvin, and getting colder as you go towards the bottom of the image until 1 milli-K in the mixing chamber.

  5. RIP Dr Heimlich. We talked about him during lunch this afternoon. He was a thoracic surgeon, he had designed his famous manoeuvre theoretically and hadn't ever put it in practice until he was rather old and living at a residence. He saved the life of an old lady with his own hands even retired

  10. RIP the maneuver man - who lived to a ripe old age, and contributed greatly. Not a lot of people end up with a life saving technique named after them.

  13. For 95% of the folks the answer is - hand it over to someone with an oven. It's doable by hand, especially with a hot air station for the power pad and then dragging along the side pins. Most likely I'll be buying a pair of AMB regs.

  21. Okey, I did nothing much till noon. After I ate, I decide to remove the acrylic panel of the egmont. Cuz I think it was blocking heat dissipation, (I was right to think that way, top panel is much more cooler now.) So I unscrew the nuts of the panel, But it just stood still. Then I pulled harder. It was glued to the top of the upper closure: So, I took off to find a solvent to remove the glue residuals, All I could find was a strong (as a girl of gratis told me) strawberry flavored acetone. So I started to scrub: The finish of the chasis was paint. So acetone removed it too. The egmont looks like this now: I'm visiting afyon for granite top cover, at first avaliable weekend. Well it looks better than with acrylic shit, as it is now, most importantly, It is lot more colder than it was with acrylic on it. I'm so high with strawberry flavored acetone smell now, All I wanted to do is playing with my fleshlight and getting some sleep. Pic Below: Sorry Dusty, my imaginary friend made me do this joke.

  24. Port Talbot in Wales is home to a massive steelworks and docks, and has a current population of 30-odd thousand. It is not a particularly nice place, frankly. And includes Aberfan, where the coal spoil heap slid into a school 50 years ago killing 116 children and 28 adults. Yet from it has come a stream of first class actors: Bernard Fox Richard Burton Anthony Hopkins Michael Sheen No one has any idea why this is the case. But in any event - RIP Bernard Fox.

  28. Just been looking at the image of the guy's passport. It is definitely fake, as compared with my expired passport from the same generation as that one. If you look just under the "f" of "of" (as in United Kingdom of...)you will see a small typed letter "P". That is in the same font and size as the lettering on the rest of the passport. You can see that the lettering in his fake is much, much larger and the wrong font. Also it is cropped and missing the bottom 20%. So the whole passport image is a complete fake. The utility bill is also a fake. As noted above the address is a fake. The bottom of the page is cropped (the bit where the bank sort code is for direct debit payment). And the last time a utility bill looked like that was more than a decade ago. And even then it did not look like that - they had by law to state the dates for which the bill related. This, from the British Gas website is what a real bill looks like https://www.britishgas.co.uk/youraccount/discover/your-bill/understanding-your-bill.html . Note that there are four pages with an astonishing level of detail. One potential route to tackling this POS scammer is for those who have been ripped off to contact BBC's programme Watchdog. They regularly track down people like that, confront them on the doorstep, and involve the police. http://www.bbc.co.uk/programmes/b006mg74 . And the Police will take this very seriously. Obtaining money by fraud is a crime, and they will prosecute, particularly as this goon is a serial offender. In fact they could probably do him for money laundering too. I feel very strongly about this clown - he is the worst of our country, preying on overseas customers who he can feel confident won't or can't track him down. Let's prove the bastard wrong.

  29. Well isn't that interesting. Kingsbury is in London. Four Pools (Lane) is in Evesham, and has post code WR11 1DJ (not WR11 4TJ - but note the close similarity). And Four Pools Lane is a road through a trading estate with no houses. WR11 4TJ is a tiny isolated development of about 100 houses about 2 miles North of Evesham in which the road names are Byrd Row, St Egwins Close, Heathfield Road, Kings Lane and Lloyd Close. No Four Pools there at all. So it is anyone's guess where precisely he is, or even what his name is - I've seen various versions even from the Head Case threads. The only other slightly obscure reference I found is that someone with the same name on his (perhaps photoshopped) passport was registered as an absentee voter in elections in the Philippines. I noticed that his 100% positive feedback on eBay from 76 sales are not possible to see - he has set his eBay account to be private. So the 76 sales could be all shill bid and entirely fictitious.

  31. It also took me awhile to dechiper but if you click that link to page 431, you'll figure it out as well. Willy was about to be scammed by "Bob" but googled him and found this thread. How is this guy not incarcerated already, when everyone knows his name, wife's name, phone number, address, passport, and bank info? No doubt most or all of these are fake except whatever burner phone he's using, but still. A lot of his info still matches the info from page 431.

  32. This fellow struck again yesterday . He was selling an SME V tonearm. Before he did that though, I saw he had no feedback at all. Oddly enough, the numerous bank accounts still has his real name. This person was previously reported in this post in this thread. https://www.head-case.org/forums/topic/786-the-headcase-stax-thread/?page=431 He tried to sell it to me, I am in the USA, he in the UK. I did a lookup on his name and his address and it showed up here in head-case.org. As thanks, I wanted to propagate the information, as it does show up in searches. Hi Bob, I did. Just tying up all the threads. Is this you? https://www.head-case.org/forums/topic/786-the-headcase-stax-thread/?page=431 Hi willy, Well if you are sure it's ok. I saw the word PayPal, and wasn't sure if it would work for me because I don't use PayPal. In which case, the details you need are Sort code 20-25-36 Account number. 805711792 Regards Rob The info you need is as follows - IBAN account no.: GB67BARC20253680571172 - name of account owner: Vingel patanao & ROBERT WOODHOUSE Vingel is my wife, and she is the lead name on the account. If only one name is required then please use vingels name - bank name: BARCLAYS BANK - bank address: Market Cross , Stratford-Upon-Avon , Warwickshire CV37 6AP UNITED KINGDOM - bank identify code (SWIFT): BARCGB22 My home address Cotswold view Four pools Worcestershire Wr11 4tj United Kingdom If you need any other information just let me know. Feel free to call me any time. And if you would let me know what value you would like me to declare on the customs form that would be helpful. The full UK retail price of the tone arm is £2350. To declare this amount would give you full cover, but the import costs would be very high I guess. Anyway if you could advise me of your wishes then I can fill out the decoration accordingly.

If you no longer want the arm then just let me know so I can readvertise it. My previous email gave options for shipping but I haven't heard back from you.

For a small parcel they are very reliable and the least expensive. I've got a figure of £61.90 gb pounds for insured shipping using their global priority service I don't have PayPal , but if you have a friend or relative over here in the UK I'm willing to go and meet them if they're not too far away from my home Or I can forward you all of my banking details. Anyway, feel free to give me a call and have a chat. My number is 0044 7729369942 One thing we need to decide on is the declared value that I put on the customs label. Obviously I don't want you to get hit with too much, if any, import duty and tax. So we can figure that one out between us. Look forward to hearing for you Regards Bob
