And if they were the ugliest, the display on a mid 1960s voltmeter was the most beautiful. I acquired a Solatron ..,I think Voltmeter ,for 30 quid around 1978, it was huge . A full 19 inch rack job and weighted a couple of stone. ..all pre metric. It had its own reference chemical cell.. 1.01920V for internal calibration and had at least that amount of resolution. 6 or 7 digits!. But the display was magnificent. Each digit was formed from an array of optical fibres and formed a very clear fully formed figure. Eg the 7 had a curved spine, the 8 two fully rounded circles. It worked by having 10 bulbs ,one for each digit. So 70 bulbs in total. Each bulb had an individual collection of optical fibres and all these were brought together at the front panel. The effect was mesmerising as the digits would move forwards or backwards as the value ,and bulb changed.
Brexit, for once some facts.

Having bought those ultra- cold refrigerators...
The Pfizer/BioNTech vaccine does not need to be kept ultracold as was previously thought when the vaccine was approved for use. The companies say it is stable at between -25ºC and -15ºC, and have asked regulators to change the terms on which it was approved. New Scientist reported in November that other mRNA vaccines using the same technology were stable at fridge temperatures, and that the same should be true of the Pfizer vaccine.

That is brilliant news. It increases the usability factor a lot!.
How very convenient
COVID-19: Oxford jab more effective when doses are delivered three months apart, study finds
The study supports the government's strategy that rolling out first doses - with a second dose after three months - is effective.news.sky.com
Let's hope its correct.
Hopefully this is true, but why has it taken so long to discover something so fundamental?
"Previously thought" and "should be",
"the same should be true" and this after billions spent on research?
And the Oxford vaccine has a similar optimistic write up on dosage timing and both curiously at the same time?
How remarkably fortunate.......
I listened to the same on LBC. A couple of black footballers were interviewed, one saying they are being used and manipulated by anti-police organisations. Both said they would not be prattling around on their knees anymore, but would be confronting and speaking out when racism occurs.
In talking down AstraZeneca's success, the EU has sacrificed lives for the integrity of the European Project
Vaccine uptake in the EU is only poor because their leaders spread misinformation about the jabs
A normal sort of opinion from the Telegraph...
A bit cynical OG?"Previously thought" and "should be",
"the same should be true" and this after billions spent on research?

What exactly do you want? Would you rather the study had found that one dose was completely ineffective? The simple truth is, the government got the vaccine rollout right and it sticks in your craw. You can’t handle it.
Because it takes time to evaluate a change. The concept of storing the vaccine at a higher temperature has probably been under consideration since long before it was approved for use.
There is definitely something wrong with your head. You should take it somewhere to be looked at."Previously thought" and "should be",
"the same should be true" and this after billions spent on research?

One Pfizer/BioNTech shot gives 85% Covid protection - study
Research findings from Israel lend support to UK’s decision to increase gap in dosing to 12 weeks
www.theguardian.com
Suggests in here when Pfizer first did study the efficy rate at 6 weeks (54%) included all those who caught disease prior to 14 days. If those are discounted efficy in week 6 is 92%.
Apparently when PHE examined data they did exactly that with data to help make decision over time delay. Might have helped had they been a little more transparent, rather than appearing to ignore Pfizer.???
Good engineers always are that's where they get to live to an old age. a heck of a lot of mistakes on dosages timings and storage seem to have been made on both Vaccines and then suddenly there's this good news? How on Earth could it be they went to all the trouble to specify in great detail we absolutely need extremely cold storage when it wasn't necessary?
Yes it's called intelligence, something you apparently don't suffer from.
There's an old saying and very true when something looks too good to be true it usually is.
If I had made such a fundamental error of specifying superdeep cold storage and then had to go back to my MD and said but if you want to, you only need a fridge.
The reaction I got would have been to be escorted to the gate by the security and told not to come back
If you can go 6 months to the Oxford vaccine second jab you obviously don't need it because the new vaccine will be along by then.
Usage in field often throws up benefits manufacturers don't recommend. During war RR insisted high boost and low fuel would destroy Merlin engine. American pilots realised doing exactly that could extend range massively.. Engines coped.
Rev limits on engines in racing oftwn go way beyond manufacturers limits. Happens all the time OG. Probably not so much in toilets.
No so, actually it matters a great deal ever change to design alters the flushing performance and can even lead to massive problems with the drains, so don't make assumption is like that ,and where potable water supply fittings are concerned unless great care is taken with design to prevent back siphonage large numbers of people have been poisoned in the past
Scepticism over Oxford vaccine threatens Europe's immunisation push
German politicians voice support for jab after only 17% of doses delivered to country are administered so far
www.theguardian.com
Vaccine negativity in Germany has led to 17% take up..!!???
I know OG, I was being flippent. Water purification over years has probably accounted for more saved lives than any other single development.
You are being a bit cynical beyond your engineering prowess tho OG.
You might use a valve or tap that you tested to 10 bar... Some user says hang on a minute we use it to 50 bar??? Neither are wrong. Manufacturer has to guarantee it, goes bust if one fails.. (if one fails manufacturer won't sell any)
Wheel bearings in cars, life expectancy 100k or 5 years? Saw bearings in Sierras that must have done 500k and still like new.
Actual usage is always different to manufacturer guidance. It's to do with comeback and deniability.
Exactly same with vaccine.
