Shortt

Post by Gareth's Downstairs Computer
Just looking at the mechanism in the master free pendulum,
what happens if the two pendulums are PI out of phase, for
this suggests that the light gravity link will drop on the
wrong side of the master pendulums impulse wheel?

The clock is not designed to work arbitrarily. I am sure it has to be
started with an approximate phase alignment. Likewise they have to trim
each pendulum to swing at the appropriate rate. The master pendulum has to
swing as close to a 2 second period as possible since that determines the
accuracy of the clock.

There are a lot of details you don't find on most web pages about the clock.

I did wonder that, whether perhaps the two pendulums had to be started
off swinging in human-judged synchrony. ISTR reading recently that it could
take several days to install and commission the pair of master - slave
clocks.

Perhaps the eagerly-awaited Hope-Jones book will reveal all!

Also found out about the previous high standard - the Riefler, having
thought that they manufactured files!

I've just discovered that the two Philip Woodward books, "My own
right time" and "Woodward On Time", both of which I purchased
some months ago on recommendation from other members of the
BHI Bristol Branch, have extensive discussion on the
Shortt / Synchronome arrangement, and all my questions have been
answered.

Apologies for wasting the time and bandwidth of those having little
or no interest in the posited mechanical phase locked loop.

Being a bookworm, I tend to oversupply myself with publications about
whatever happens to be my interest of the day, to the effect that it
is difficult to keep track of all their contents.

Nevertheless, apologies.

This is one of his standard excuses he uses when he is out of his
depth/decides he can't 'win'. He suddenly discovers a book etc, which he
has had a long time, which 'explains everything'.
We've seen it before with his 'Big K' nonsense- he claimed he hadn't
noticed the T (as in 1/T if you prefer) in the standard maths of DSP.
The 'not noticing' had lasted decades, supposedly.
Any 'insights' he offers would be useful as fertiliser but little else.

Yikes. Apparently I've stumbled upon a rather prickly Google group. My spell-checker noticed alternate spellings for 'pretences' and 'fertiliser' so I guess it's a British group as well.

I just fix clocks in a sort of rural part of Ohio, and I'm working on a cuckoo clock with a reluctant music box. Sorry to intrude.

If you read the posts that don't involve the OP of this thread you will find
this group to be civilized, but very quiet. When someone asks a question
they may not get an answer, but nothing untoward will happen.

It just happened that the OP of this thread recently entered a discussion of
the Shortt clock and was discussing it in another group which is ham radio
oriented. He misunderstood an aspect of the operation and his detractors
started to pile on. This is a very common turn of events in the ham radio
groups they usually post in. So much that I have quit reading most of them.
I don't expect this to continue here.

If you have a question to ask, please start a new thread and ask away!

I did not misunderstand. You and I held different viewpoints and mebbe
were talking at cross purposes so I could just as easily say that you
misunderstood!

The reay poster quoted above usually dives in with false and malicious
abuse directed at me which is why he is kill filed here and why I did
not see Mark's post wherein he quoted reay directly.

Absit invidia.

I'm not going to challenge anything Gareth has said to prevent a continuing
thread, but this is exactly what I was referring to. I see the ham groups
were removed from the reply-to list, so there won't be the Greek chorus.

If Mark creates his own thread I expect he will get responses without the
rancor.

Well, that's interesting. Years ago when I was active in radio, ham radio people always seemed to be the most collegial of hobbyists. Equally puzzling is the fact that a group dedicated to communicating with each other by digital, analog, or International Morse Code would have a Google group at all.

Now I just fix clocks.
