Improvements in the Blown Arc for Projection
The air-blown carbon arc has been further refined by the use of a noncoated graphite rod negative which is rotated to reduce carbide deposits to a minimum. Design of components has been simplified to facilitate maintenance and servicing. Controls have been simplified for ease of operation in the theater. The advantages of the infrared transmitting reflector and new 25-in. positive carbon have been consolidated in this development.
