Abstract :
The practicalform taken by the apparatus is indicated by photographs and line drawings. The factors governing the choice of the cell liquid, the crystal frequency, and the lens powers are explained, and a brief description of the electrical apparatus, with circuit diagrams, is given. For the projection of large pictures in cinemas an arc lamp is used but otherwise the optical and electrical components require little modification.
