Dictating Machines to Use Magnetic Tape (Oct, 1934)

Dictating Machines to Use Magnetic Tape

With the development of the steel tape method of sound recording, present day dictaphones may soon become obsolete. In demonstrations at the Century of Progress sound was stored in the magnetic ribbon for only a few seconds, but engineers believe it possible to construct a simplified dictating machine set along similar lines.

With the use of large rolls of the steel tape, there would be no need to change records as frequently as in the present apparatus. Court proceedings could be stored indefinitely.

Magic HOUSE Makes Own WEATHER

Features at the Century of Progress it is a magic dwelling which literally makes it’s own weather.

The secret of the process lies in a remarkable air-conditioning system which cools the air when it is too warm and heats it when it is too cold, dries it when it is moist and humidifies it when itis too dry, cleans it of pollen, dust and odors and keeps the air conditioned at all times.

Sensitive recorders placed on window sills close the windows if a shower comes up; and awnings are lowered or raised automatically by action of the sun’s rays.
