(1) Light from the projector passes through the stationary polar-

i z e r o f t r a n s p a r e n c y and the rotating polarizer of the

spinner. The optical effect of this sequence is an illusion of

animation.

(2) The mounting clamp fits over the lens housing of the pro-

jector; source power for the spinner is derived from an ac

convenience outlet available on certain projector models. On

other models, another 115-volt ac source is used.

(3) With the mounting clamp in line with the spinner housing,

the equipment measures 9.31 inches long by 6.63 inches wide

by 4.59 inches deep. It weighs 21/2 pounds.
