Production Background The new lamps are being built by Motiograph craftsmen under the personal supervision of Theodore O. Hall who has had a lifetime of experience as a designer of projection light sources. The new models are designed and engineered to give maximum performance. They are precision built and easy to operate and adjust. Experimental models of lamps were in actual operation in drive-in theatres for over a year at a number of points through¬ out the country prior to full-scale produc¬ tion. The experience acquired in these installations enabled the designer and the manufacturer to eliminate the minor diffi¬ culties which are occasionally part and parcel of a newly designed product. The Motiograph-Hall 75/115 High In¬ tensity Arc Lamp, tested and validated under actual operating conditions in con¬ ventional and drive-in theatres in 1948, is scheduled for plant production in 1949. Construction The moving portions of the lamp con¬ sist of comparatively few parts; and all of these have been carefully machined and made wear-resistant. The arc burner mechanism is built as a complete unit which can be readily removed if servicing is required. The spacious housing is constructed with smooth inside surfaces to facilitate cleaning. In addition, a false bottom is provided which extends under the en¬ tire burner mechanism. It can be readily removed. The positive carbon contacts are made of bronze. This alloy possesses the best heat conductivity among metals and alloys, consistent with resistance to oxidation and scaling. The contact surfaces are lined with pure silver l/16th of an inch thick. Both silver and bronze will readily con¬ duct current and dissipate heat rapidly, without scaling. The lamphouse is comprised of a formed heavy gauge sheet steel base to which two sturdy aluminum castings are attached by polished steel rods. These castings form the front and back of the housing. Both doors are double-walled to effecttively insulate the outside surfaces from the high arc temperature. The usual ruby glass observation ports and arc image projector are provided.
