The machines here shown are the laboratory models used in the
development of Radio Vision and Radio Movies for the reception in the
home of broadcast studio performances, i. e., dancing girls, public
speakers, pantomime, marionettes, motion pictures; and, by remote
control, outdoor events, sports, etc.
The lower illustration shows a 10″ disc rotating in front of a prismatic
ring, synchronized by a variable speed of the motor. The light is in the
round box at the top of the standard behind the lens carrier, and shines
through lenses and prism (onto a picture screen) as they pass, the light
fluctuating in value with the incoming radio signals to make up a
complete picture every one-sixteenth of a second.
The upper illustrated mechanism differs from the lower one in that it
has a second overlapping prism for optical correction.
The casing enclosing the mechanism is not very large, and contains,
besides the radio vision mechanism, the radio receiving set, and a
loudspeaker, so that an entire opera in both action and music may be
received.
[Illustration:
The prismatic ring can be rotated to follow any moving object; e.g., a
motion picture film; or if fitted with a high-reading automobile
speedometer the speed of an airplane or dirigible can be read
directly off a dial by the navigating officer.

[Illustration:
The rotation of the disc _A_ carrying lenses _b_, _c_, _d_, etc.,
sweeps
the image of the light source _C_ across the screen _F_ in a
horizontal
direction, while line displacement in a vertical direction
is effected by reason of the changing angle of successive prism
elements.

[Illustration:
The rotation of the disc _A_ carrying lenses arranged in a spiral
causes the light _L_ to sweep across the screen _M_. A revolution
every sixteenth second gives a motion picture screen effect.
