(1) Note. To be classified herein a patent must have significant motion picture structure as the cooperation of two photos:graphic elements such as a lens and a gate, or the details of one such element such as a gate. Patents which merely recite such an element broadly as a part of a magazine combination are classified in Class 242, Winding, Tensioning, or Guiding. If only the construction details of the magazine are recited the patent is classified in Class 220.
