Abstract
456,617. Gearing for stopping machinery. OPTICOLOR AKT.-GES., Glarus, Switzerland. Nov. 12, 1935, Nos. 31324 and 31325. Convention dates, Nov. 13, 1934 and March 21, 1935. [Class 80 (ii)] [See also Groups XX and VIII] The apertures corresponding to the three basic colours in copying lenticular colour films are adjusted according to the perforations of a controlling strip by means of shutters 23<a>, 23b operated by racks 24<a>, 24b from a gear-wheel 25. The gear-wheel is coupled by a lever 28 with an arm 29 driven by a continuously rotating shaft 30 through a friction coupling. The arm 29 is normally held from rotation by a pawl 31 engaging a fixed toothed wheel 33, the opposite end of the pawl carrying a roller 31<a> resting in recesses in discs 32<a>. When the circuits of the electromagnets 34<a> are closed by the perforations in the controlling strip, the discs are rotated, lifting the roller 31<a> out of the recesses and thereby freeing the arm 29 which rotates until the roller 31<a> drops back into a fresh set of registering recesses.
