Abstract: Dyeing or finishing process characterized in that textile materials are impregnated in a padding machine with aqueous dyeing or finishing baths which contain, besides graft polymers, which may be obtained from a product of addition of an alkylene oxide to an at least trivalent aliphatic alcohol containing from 3 to 10 carbon atoms and methacrylamide or acrylamide, and in that the fixing of the dyes or of the finish is then performed continuously by a treatment with microwaves for 5 to 30 seconds.The process permits an excess water input on all the textile materials and a rapid fixing by the microwaves.

Abstract: The present invention relates to apparatus for photography under water, and is directed generally to the complete or partial elimination of the fluid-tight bushings inevitably necessitated for the controls of such apparatus, by transferring to the exterior of the fluid-tight casing of the apparatus, the various devices necessary for the control of exposure of the light sensitive material. The diaphragm of the camera lens is arranged in front of the lens, outside the fluid-tight casing, and is therefore under water when the apparatus is immersed. This permits the variation of the aperture and the exposure time without need of access to the interior of the casing. Also, the lens is produced in the form of a thick meniscus with a concave inlet diopter, the convex diopter of the whole unit being added by the liquid immersion medium itself. This lens has the advantage, apart from the transfer of the diaphragm to the exterior of the casing, that it has great resistance to pressure.
