Tonight - July online meeting of the Early Television Museum community

Hi to All,

Like many viewers residing in Europe, i watched the YouTube replay of the july 24th Zoom meeting. 8PM EST is 2AM in France and 1AM in the UK.
Maybe someday there will be a US lunch time meeting & more from overseas would participate.

Same echoes from England:

One of the participants mentioned a 441 line Nipkow Telecine scanner made in Germany whose disk rotated in a partial vacuum. I wanted to add that alongside the safety issue of shielding a +/- 30" disk in the event of breakage, it was also done to have clean air devoid of dust. Scanning at 240 lines (Baird), 343 or 441 implied holes so small that even minute dust particles could clog scanning holes.

Baird's 240 line Telecine Scanner used at Alexandra Palace was also enclosed with partial vacuum.

It was nice to see so many friendly faces from my travels to the ETF...

Best Regards
