Abstract: Aqueous dispersions of polyurethane polymers in ammonium salt form are prepared by reacting diisocyanates with a polyhydroxy, carboxylic acid to form an isocyanate- terminate prepolymer that is united with an unsaturated fatty acid ester polyol to provide carboxylic-containing, water-dispersible polyurethanes having properties exhibited by organic solvent-based, oil-modified polyurethanes. The aqueous dispersions can be formed by neutralization of "oil-modified," carboxylic group-containing, water-dispersible polyurethanes with ammonium salt-forming materials such as ammonia and amines. The aqueous dispersions are especially desirable coating compositions. An organic phosphite may be incorporated in the compositions to control the development of hardness in films made from the aqueous dispersions and thereby avoid the formation of wrinkles in films that are made from the compositions.

Abstract: A process for fusion joining the ends of optical fibers includes aligning the ends of the two fiber cores to be joined facing each other such that at least one of the ends is free to be displaced laterally and there is no axial force between the two ends. The ends of the fibers are heated by producing a heat field with a predetermined distribution, for a predetermined period until attenuation of light transmitted through the fused joint increases, so as to cause partial fusion of the cores while maintaining sheathing of the fibers intact. A device for fusion splicing the two ends includes two opposed fiber supports for maintaining the end portions of the optical fibers to be fusion spliced in an approximately aligned position, the supports being slidable along the axes of the fibers being mounted on said supports such that their ends are free to move laterally. Optical means, such as a binocular microscope, is provided for checking whether the ends of the fibers are in the position where they engage one another without exerting any axial force on each other. A propane-oxygen flame heating device establishes a controlled distribution of heat field for heating the core ends.

Abstract: A prosthetic socket 1 is made in a generally crescent shape with an outer cylindrical surface and includes horns 5, 6 which may be contracted, in order to allow it to be introduced, in the manner of a clip, in a cylindrical osseous cavity, where it is held by elasticity, without any cementing. The anchorage of this type of prosthesis is made directly onto the bone, using materials with a Young's modulus very close to the Young's modulus of the spongiosa tissue of the pelvis guarantees longevity of the anchorage, which is protected from loosening which may occur when cements of the methyl methacrylate type or others are used, such as metal or ceramic materials designed to be self-fixing, but of which the Young's modulus is sufficiently different from the Young's modulus of the bone that mechanical stresses may occur causing loosening. The invention also relates to an artificial head of a femur of three part construction.
