I use a screen reader program called JAWS. JAWS reads & speaks what is on the monitor. Graphically I am at a loss, but this is not a problem. I know what vacuum pumps look like. I will often ask the vendor to forward a picture to the customer. These computers are a wonderful life line from me to you. I keep updating my programs. Now I can offer a 24-7 computerized service. Any time of the day or night you can e-mail me for a pump, etc. I email my Associates (vendors) through out the country. I receive replies as soon as they start work.

Vacuum pump(14)

In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been evacuated.

The study of vacuum then lapsed until 1855, when Heinrich Geissler invented the mercury displacement pump and achieved a record vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, and this renewed interest in vacuum. This, in turn, led to the development of the vacuum tube.
