it is necessary that the input voltages thereto be within predetermined limits. Additionally, certain of these circuits are designed to respond only to a relatively high voltage impulse or "spike" as may be derived from the instantaneous powering-down of an inductive network. To adapt such circuit...
A moment after the film is exposed through a thin four-element lens, the whole film card is ejected from the camera by a small motor powered by a flat six-volt battery that is packed with each set of 10 film cards. As a card leaves the camera, it passes between two tiny steel rolle...
