I am finding a lot of things harder in life each year; computers are
the biggest problem, programs and website get changed or disappear,
or Microsoft make an improvement which prevents me working in a way
I have been doing for 20 years...

I wonder if anyone can help me with a patent search problem.  When
I was last researching patents five years ago I could simply type in
a name of an applicant or a patent number for USA registered patents
and I would get an answer.  When I type in a 6-digit number such as
569,233 which is about Polyphon disc musical boxes nothing comes up
at all any more.

Does anyone know of a web site that is reliable and will give me the
answers I need, please?

Thank you,
