30 Transactions of S.M.P.E., Vol XIII, No. 37, 1929
The scope of this committee's activities is rather wide, including particularly the sprockets used in handling 35 mm. film in projectors, cameras, and processing machinery. It has come to the attention of the committee that some equipment is now being manufactured which does not conform to the standards officially adopted by this organization. The subcommittee was therefore requested to look into this situation and to attempt to reconcile anj^ differences between our standards and existing practice. If conclusive evidence can be produced indicating that our present standards are unsatisfactory^, revision should be made. This subcommittee was charged with the responsibility of attempting to clear this matter up at the earliest date possible.
It was suggested that charts similar to those already adopted for 16 mm. sprockets be prepared for 35 mm. sprockets and that these charts should show standard dimensions for sprockets differing in number of teeth and angle of film contact. This subcommittee was requested to deal with this matter.
The subcommittee w^as also assigned the subject of standardization of cores on which manufacturers are to supply negative film, as suggested by the Seventh International Congress of Photography. The sample core submitted by the Congress was turned over to the subcommittee for analysis.
Certain other matters, such as the position and size of printer notches on negative, were also assigned to this subcommittee.

While this Society may not be as vitally interested in the substandard films as in the standard 35 mm. film, it seems desirable to give some attention to this field. The standards already adopted seem to be quite satisfactory, but there may be a few minor points requiring attention.
