Abstract

429,254. Toothed gears. ZEISS IKON AKT.-GES., 72, Schandauerstrasse, Dresden, Germany. Aug. 22, 1933, No. 23380. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 1, 1934]. [Class 80 (i)] [See also Groups XXXVIII and XX] In a picture-projector combined with soundreproducing apparatus, vibrations which would interfere with the sound reproduction are suppressed by constructing the gear wheels or other moving parts of the projector of a material consisting of " pressed long-fibrous vegetable fibre such as cotton " without any binding agent. Parts of " the intermittent movement device (single tooth wheel, intermittent disc) and the feed roller " may be made of this material.
