In 1934 a group of engineers looked into the future of the motion picture industry. They were planning a copper oxide rectifier for projection service. The foremost thought in their minds was that you fellows must be freed from the fear of frequent design changes if you are to buy the equipment you need.
The result of this careful planning was the conservatively-designed G-E Copper Oxide Rectifier for Motion Picture Projection Service.
Its designers gave you the 3-unit transformer for greater efficiency. They remembered that you wanted a minimum of operating noise and heat, so they provided for it. A remote control system was added to enable the rectifier to be controlled from the lamp
pedestal. Control of the rectifier was so simplified that the simple opening and closing of the 110-volt control circuit was sufficient to start the blower motor, close the relays, and automatically connect the 3-phase line to the transformer.
Today that G-E Copper Oxide is the same rectifier. The single major change was the division of the unit into two parts for your convenience in handling and installation.
The story will be the same in the future. You can buy with confidence now, because changes will be few. It was “right” to begin with. That’s what counts.
