Title: An improved method of producing colour photographs, more particularly cinematograph films
IPC: G03C7/28
Filed: 1935-01-22
Abstract: 446,206. Colour photography. GASPAR, B., 59, Rue de Tenbosch, Brussels. Jan. 22, 1935, No. 2081. Convention date, Jan. 23, 1934. [Class 98 (ii)] Colour photographs or kinematograph films are produced by uniting two or more multicolour images each of which is not sufficiently powerful to act as a colour photograph per se. Each of the multi-colour images may be formed by copying, or by exposure in a camera, on several superimposed coloured light-sensitive layers applied to each side of a film, or may be formed in a single emulsion material of juxtaposed or superimposed, coloured and sensitized particles. In an example, to each side of the film there are applied three emulsion layers, a weak yellow layer containing chrysophenine, a weak purple-red layer. containing Diamine Fast Pink and sensitized to green with thioisocyanine, and a layer coloured blue with Benzol Light Blue and sensitized to red with pinacyanol. The material may be printed from a multi-colour screen master either by contact, or by optical projection in split-beam apparatus for exposing the two sides simultaneously. The dyestuffs may be fixed and development of the layers carried out as described in Specifications 395,718, 397,159, 397,188, 397,192, 408,991, 415,756, 428,158, and 434,305. When employing materials comprising superimposed particles, three emulsions are prepared, e.g. blue-green sensitized to red, purple sensitized to green, and yellow sensitive to blue. They are re-emulsified and coated onto a support. The resulting picture is a weak one and is combined with a second similar picture to make a saturated colour image. In the production of images for direct observation, certain of the coloured part images are produced by transfer and the remainder on a transparent foil.

Filed: 1958-01-28
Abstract: 833,943. Viscometers. CHEMICAL PRODUCTS CORPORATION. Jan. 28, 1958 [Jan. 29, 1957], No. 2882/58. Class 106 (2). [Also in Group VIII] Apparatus for measuring the viscosity of a liquid comprises a container 20 having entrance and exit openings, drive means 25 for feeding an elongated piece of material 14 through the openings and container, means 72 for applying a force on the container 20 opposing that exerted by the drive means 25 and indicating means 70. As shown, the liquid whose viscosity is to be tested is applied in the container 20 as a coating to a yarn 14 and is hardened in a unit 24 before the yarn is passed to a spooling mechanism 28. The container is supported by wires 40 from a platform 42 which is adjusted by hand wheel 54 until a pointer 60 on the container is directly beneath a bob 56. In this position the force applied by the driving rollers 25 is exactly balanced by the force applied by a torsion spring 72. This is indicated by the angular movement of a scale 70 and is a measure of the viscosity of the liquid coating. The entrance hole of the container is made substantially larger than the diameter of the yarn 14 and the exit hole is small enough to strip off excess liquid from the yarn. The container is filled through an opening 38. In an alternative embodiment, the fixed end of spring 72 may be adjusted instead of the platform 42. Alternatively, the container 20 could be floated in a liquid.
