Weird Science

[rld-tv01]

I have an interest in many mechanical and electrical devices and other weird science devices. On a trip last week to pick up a TV the seller showed me some of his collection of stuff. So I bought what he said was a 1920(s) radio transmitter in a wooden box. The metal label said Hogan Brevatherm Shortwave Diathermy McIntosh Electrical Chicago Illinois. It turns out the 1930(s) radio transmitter is a medical (quake?) shortwave device to lessen pain in the human body. The patents listed on the device (1915-1920) are for Deforest and Western Electric for Shortwave transmisson using a single tube. The wavelength is 23.3 meters reserved for medical and experimentation according to google.

I have in my collection a 1920s Dental X-ray machine, an old Arc lamp, an alluminum arm with an electrical wire and plug, high school physics labs motor and associated apparatus for proving centripical force, physics labs color wheels, collection of old transmitter tubes, 1920s 35MM Powers theater projector, 10+ magic lanterns, large 1920s battery in wood box, 1930s car headallight aligner, 1920 dictagraph machine, Windcharger for radios, crookes tubes etc. This is besides my 85+ TVs, radios, tv color wheels, uhf converters, anntennas etc.
