Latest Patents

Irvine W. Smith holds a patent for a Film Deceleration Unit. This invention involves a projector equipped with a rolling loop film transport mechanism. The film decelerating cam unit is strategically positioned in advance of the projector's aperture. Deceleration pins, which are attached to vertically spaced arms from the cam unit, engage with the film's upper and lower marginal perforations. As the film moves towards the aperture, these pins decelerate the film for each frame advancement. The cam unit features two cams; one facilitates the deceleration and return motion of the pins, while the other cam manages the pins' advancement and retraction. This design reduces acceleration forces and stresses on the cam, allowing for operation at higher frame rates and with smaller rotor gaps compared to prior art.
