three-phase power transformer and a common choke to both DC outputs.
With the use of silicon rectifiers for AC to DC conversion, shelf life is no longer a problem. Silicon has the intrinsic property of no aging. This permits stocking of a spare rectifier without fear of detei-ioration.
THE NEW XENON LAMP
Coming to the front rapidly, is the new xenon projection arc lamp for 16mm and 35mm projection. Offered to the industry are several makes and models to fit various needs in the motion picture theatre and 16mm field. Each manufacturer, of course, offers special features in the particular design of his lamp, such as type of mirror, mechanism for holding and adjusting bulb and lamphouse design. Featured is the power supply for this lamp, a very, very essential and important unit for successful operation of any make of xenon bulb.
One company, XeTRON, Inc., has developed a modification for 16mm projection and by using xenon bulb and rectifier, this lamp will deliver at least three times as much screen illumination as normally developed by such a projector using a 1,200-watt incandescent bulb, plus a high intensity light similar to that from a high intensity carbon arc, at very little extra current consumption.
In order to obtain maximum light output, it is paramount that the lamp be perfectly aligned optically, and then it should be adjusted as per the manufacturer’s instructions. While these adjustments are not too critical, they should be carefully made in order to obtain full light output and an even screen illumination from center to edge. There are manual adjustments for obtaining satisfactory overall screen illumination.
BRILLIANT LIGHT AT APERTURE
The Zeiss-Ikon Xenosol lamp has many outstanding features. The well-known Zeiss-Ikon optical system produces a very brilliant light spot at the aperture plate and will give excellent overall screen illumination when correctly adjusted. Another feature is the principal mirror (356mm in diameter) located on the back wall of the lamphouse. The xenon lamp is next, followed in line by the auxiliary mirror and the ignition device for lighting the lamp (lamp will not light if lamphouse door is open) .
Xenoblock — This unit is the optic heart of the Xenosol system. It is available alone and allows theatre operators to enjoy the advantages of xenon light projection by using existing carbon arc lamphousings. The Xenoblock forms a complete unit and is very easily installed in many standard lamphouses. With rectifiers (specially designed Sil-Tube (selenium type) and Xenoblock unit, you are provided with all the advantages of a complete Xenosol system.
The Zeiss-Ikon XenOoOl lamp system is distributed by Cine Electronics, Inc.
We have on our desk several reports from theatres using xenon bulb equipment, one that has been running over 35 hours and still getting excellent results, and light output test was made which showed almost 100 per cent output. In some cases there
