I notice in the machine that you have a different methodto the usual way of mounting condensers that has been oneof our special points. With the Simplex projector it is possible to get the verybest conditions with the condensers, as the back mount is ad-justable; when the right selection is made the convex sidesshould be as close together as possible in order to have aperfect foci. If the condensers are properly selected (taking. SHOWING HEAD OF MACHINE W I 111REMOVED 1 IREPROOF COVERS advantage of our adjustable mount) the result will be a per-fect white light all over the picture, entirely eliminating theobjectionable blue spot which causes so much criticism of theoperator. How about the shutter arrangement? I am very proud of this point; while the shutter is sentout approximately adjusted, it is not necessary for us to payparticular attention to this very important detail; there is asmall knurled knob on the lamphouse side of the mechanismjust below the automatic shutter. As soon as the picture ison the screen, if there is any perceptible ghost, it is only nec-essary to turn this knob to the right or left (with left hand)to bring the shutter into perfect alignment while the ma-chine is in motion. This is a real boon to the inexperienced
