Abstract: The invention relates to an emulsion comprising an aqueous gelled outer phase, a non-aqueous intermediate phase and an inner phase containing an active ingredient incompatible with the gelled outer phase, wherein the outer phase comprises one or more anionic hydrocolloids in an amount of 0.1% to 5% by weight of the weight of the outer phase, the intermediate phase comprises an oil, and the inner phase containing the active ingredient is encapsulated by the intermediate phase. The emulsions are useful for the preparation of antiperspirants, sustained release drug formulations or personal hygiene products.

Abstract: A method and apparatus for rejuvenating worn or used balls, e.g. balls used in the game of racket ball by subjecting such worn or used balls to steam heat while confining such balls to a closed environment.

Abstract: A method of painting a photographic image on any surface, including a vertical surface or uneven surface. The method described is comprised of transferring the photographic image to a screen having a particular minimum mesh and then securing the screen to the surface onto which the photographic image is to be painted. The screen being flexible is secured to the surface in intimate contact and following substantially the contour of the surface to be painted. Paint is then sprayed through the photographic image on the screen in a series of applications of very thin layers with the paint allowed to dry between each application. The paint is mixed to such a consistency that it will rapidly dry almost as it is applied. When the painting is finally completed, the screen is removed by carefully peeling it from the surface, leaving the photographic image painted on the surface.
