Title: Process and apparatus for the manufacture of foliated glass and product produced thereby
IPC: C03B37/005
Filed: 1938-04-22
Abstract: 503,369. Making foliated glass. CORNING GLASS WORKS. April 22, 1938, No. 12145. Convention date, May 25, 1937. [Class 56] A process for making foliated glass consists in flowing molten glass into a thin film, subjecting the film to a gaseous blast which attenuates and solidifies the glass, and then breaking the film into foliated form. The molten glass is allowed to flow in a regulated stream from a furnace forehearth 14, Fig. 1, into a rotating heated bowl 38 having a central aperture surrounded by a kerb 76. The glass flows over the kerb and forms a cylinder C which moves downwards by gravity through an enclosed chamber formed by a cylindrical jacket 83. The thickness of the wall of the cylinder is controlled by the rate of flow of the molten glass into the bowl 38, and by the amount of heat supplied to the bowl. Air is blown into the cylinder C from an adjustable pipe 50 to set the glass and blow it into foliations, and the breaking-up of the glass is assisted by air blown into the jacket 83 from pipes 82. The glass may be broken-up, also, by a rotating blade 89, Fig. 2, the fine flakes of glass being drawn into a side tube 87 and a bin 90 by an air blast created by a fan 86, while the heavier cullet falls into a receptacle 84. The air from the pipe 50 prevents the cylinder C from collapsing, but the action of the air may be assisted by passing the cylinder between rollers to flatten it and reduce the area through which the air escapes. In some cases, the bowl 38 may not be rotated. An annular burner 75 may be arranged below the outlet of the bowl.

Patent GB-131319-A (GB)
IPC: G03C7/46
Abstract: 131,319. Lawshe, A. R. Aug. 7, 1916. Colour photography.-Multi-colour photographs are produced by (1) exposing two superposed plates or films through a .screen in a camera to obtain separate colour-record negatives, (2) preparing from these negatives positives having red and green images respectively, and (3) treating the green image at the parts corresponding to blue or colours containing blue in the original subject so as to render it blue. The red image may be a transferred carbon image on a paper support. The green image may be obtained by printing on blue carbon tissue which is sensitized in a bath containing non-actinic dyes to reduce sensitiveness and contrast, a suitable bath being naphthol B, 5 to 10 grains; amaronth, 5 to 7 grains; ammonium bichromate, 24 grains; water, 1 oz.; and ammonia 20 drops. The blue image is transferred to a transparent support, and the strengths of the images are tested and adjusted by placing them in register and further developing the darker one if necessary, the blue image being preferably developed further than the red one. The blue image is then treated in an alum bath, washed, and dyed in a yellow bath comprising preferably 1 to 2 grains of alizarine yellow to each ounce of water, the resulting green image being again tested against the red image, and the red image being further developed if necessary. The green image may alternatively be obtained by using blue and yellow pigments in the tissue which yield a bright grass or emerald green image, or by printing in clear gelatine and dyeing the developed print in a blue dye followed by a yellow dye. The green image is then brushed over at the parts corresponding to blue, and to colours containing blue in the original subject with weak muriatic or other acid to decolourize the yellow dye or pigment, and produce a blue image at those parts. For transparencies and lantern slides the pigmented gelatine may be transferred while in the sensitizing bath to sheets of celluloid or other transparent material, and the celluloid &c. may have a prepared surface, or the sensitizing bath may be made alcoholic, to ensure the adhesion of the gelatine and celluloid &c. The gelatine on the transparent base is then exposed and treated as described above. For kinematograph films, celluloid bases are used for supporting the sensitized gelatine, and the bases of the finished prints are united, with uncoated sides in contact, by passing the prints through a celluloid solvent and subjecting them to pressure.
