[Also in Division F4] A device for screening a light source consists of a number of superimposed thin sheets of transparent material, each of which has printed or deposited on at least one face a design or part of a design which in the aggregate forms the desired screen. The designs are superimposed in register.

The designs may be such as to produce portrait or picture instead of a geometrical pattern.
