Fortuntely the decimetre seems to have disappeared

Presumably it has been decimated…?

Hmmmm, what a vulgar discussion, let us hope it stays rational and proper, and doesn't veer into the improper.

…and those Metric bigots all seem to be just a bit too "holier than thou" don't they?

I'll get my coat…

Reduced by 10% That would leave us with ninometers.

What I can't understand is why we use hectares instead of ares.

I'm off for a hectolitre of best scotch.

It all goes to show that units of measure are a pain in the ares. Mind you, after a hectoliter of best scotch, you would have a wee pain in the wallet, not to mention the head

Hmmmmm, I can't work out if I'm being agreed with, or insulted…………

Morgan,

Yes, the Strowger System was reputedly invented by Almon B. Strowger who was indeed American, but the system was much refined into the eventual workable system that we all love. Or hate!

Having said that, the GPO as it was, initially used Strowger type selectors from a number, five I think, of different companies, which although they fitted a standard cradle and bank, were between themselves not really compatible, ie spares for Siemens, say, would not fit, say, ATE. Then, in the '30's I think it was, the GPO designed it's own Strowger selector which was called the 2000 type and all manufacturers built to this design, hence solving the spares compatibility problem.

The 2000 type selector had a number of other advantages as well over the older selectors which became known generically as pre-2000. The 2000 type switch lasted until the demise of the Strowger system in the UK although there was an attempt in the '60's to introduce a cheaper alternative. This was, unsurprisingly, known as the 4000 type selector and was functionally identical to, and hence fully interchangeable with, the 2000 type and used the same cradle and bank. However, it did not last because, I believe, it was not as reliable as the 2000 type.

Those were the days! I have worked on all thiose systems, before moving onto Crossbar, TXE2 and 4 and finally system x and y.

While the older strowger type equipment kept a lot of TO's inemployment with an amazing array of adjustment tools. the modern electronic sytems we now have, only require the TO(i think there must only be one left now!!!) to have an Alsation dog rather than a toolkit.

The dog being there to stop the TO from touching the equipment, as engineers messing with the kit caused more problems than leaving it alone…………………

Well, they were clearly either real or imaginary…

Howard,

A question.

Are you the Howard Winwood from Sheffield who used (I think) to work with Steve Bass whose line manager was John Seymour during the early '90's? Because if so, I was on the same group at that time. And no, I'm not the EL&P Peter Shaw.

If you are, you may wish to converse via private messaging.

Peter G. Shaw

Tony,

We need to root this out. It's avery bad sin, cos everythings going of at a tangent. Its a prime candidate for some sort of reciprocal arrangement, before everyone is divided into warring fractions.

Neil –

Too much more of this hyper-bolics & we will all be under the cosh.

You lot are all vulgar factions!

I no , i no, it's speld rong!

[Tony JeffreeParticipant @tonyjeffree56510]

either that or you're being deliberately obtuse…

Whilst your arguments are complex your ideas are more imaginary than real!

That's ab-surd!

[NJHParticipant @njh]

Now then Tony this thread has drifted so far into the imaginary with all this hyperbole that the original arguement is lost and its functions are now truely all hyperbolics!

Oh dear Oh dear!!!

My wife has just looked at this thread and says that it all seems to have gone full circle. Who am I to argue – best get on with some useful domestic chore I guess!

Best we stick to the previously mentioned circular transcendental functions then – Andrew

I left my expensive Starrett calipers in a damp shed and they died, since then i'm using the Chinese ones there is no difference in the reading but, they are rough as a goats knee, maybe you could stone them to slide smoothly i don't have the inclination to find out.

I had a Victorionox £70 multi tool which i dropped in the canal, it was non magnetic stainless steel, i nearly cried, now i'm using a toy Chinese one of these too.

I have a Victorinox Swiss Army Knife which I've had for about 30 years. The spring in the scissors broke so I emailed them to see if they would sell a new spring. They told me to send it back to Switzerland for repair, free of charge, as they are guaranteed for life. Will you get that service from China?

Russell.
