Abstract

258,842. LumiÞre, L. Sept. 28, 1925, [Convention date]. Addition to 256,252. Diaphragms.-The diaphragm described in the parent Specification is mounted so that the ridge p between the two parts a, a<1> of the diaphragm is in a plane with the two parallel opposite edges that are fixed to the supporting frame c<2>. The two sides c, c<1> of the frame are cut to a prismatic form, the faces against which the diaphragm bears being at a tangent to the surface of the diaphragm.
