Abstract: This invention relates to a process for the removal of dissolved species from aqueous solutions, which comprises contacting said aqueous solution with an emulsion, said emulsion comprising an exterior phase which is characterized as being immiscible with said aqueous solution and yet permeable to said dissolved species, and an interior phase which contains a reactant capable of converting said dissolved species to a non-permeable form. The dissolved species permeate the exterior phase, into the interior phase where they are converted into nonpermeable forms and thus retained in the interior phase of said emulsion. The aqueous solution, depleted in said dissolved species, is separated from said emulsion and the emulsion cycled for reuse. In one preferred embodiment said dissolved species are ions, and an ion exchange compound is incorporated in the exterior phase of the emulsion, to promote the permeation of said ions through the exterior phase.

Abstract: Compositions possessing a porous, high specific area, silica-rich surface, or capable of developing such a surface in vivo, form strong bonds with bone tissue. These compositions are thus excellent materials for dental and surgical implants, or the coatings thereof. Examples of such compositions include highly porous glasses and glass-ceramics comprising at least about 80 weight percent silicon dioxide, hardened inorganic cements such as Portland cement and known silicon dioxide-based biologically active glasses and glass-ceramics. Neither calcium, sodium nor phoshorus compounds are necessary ingredients. Cements which develop the above described surface characteristics in vivo form a strong bond with both bone and implant when used in the fixation of dental and surgical implants, especially those made or coated with a biologically active silicon dioxide-based glass or glass-ceramic.

A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution. In operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred into the reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe. The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution.

Abstract: A steel wear belt having a prepared inner surface with an inner diameter large enough to pass over the weld upset on one end of a drill pipe tube but too small to pass over the tool joints is installed about the pipe over a prepared outer peripheral surface thereof. The belt is installed prior to one or both tool joints being welded to the tube. The belt is secured to the tube by injection molding a mounting layer of high polymer material, e.g. plastics or elastomer, preferably self bonding and thermo-set, between the prepared surfaces. There is employed a diametrally split mold disposed about the belt and wedged together by tapered end rings. The rings have inner diameters large enough so they can be removed by passing over the tool joints if they are attached to the ends of the tube before securement of the wear belt. The pipe is plastics coated internally from tool joint to tool joint. The plastics of the internal coating and the polymer of the wear belt mounting are cured.

Abstract: A method for producing cast, superalloy, ferrous and titanium articles comprising the formation of a material void in the cast article, for example by utilizing a core during the casting operation or by machining a void after casting. The void is sealed relative to the surrounding atmosphere and the article is then subjected to an elevated temperature and pressure treatment in a gaseous atmosphere whereby the metal in the area of the void will yield so that the void is partially or totally eliminated. The pressure application is carried out at a temperature such that local deformation of the cast structure occurs in the region previously occupied by, and adjacent to, the void whereby a fine-grained recrystallized structure is developed in this section. Grain refined cast articles are characterized by superior low-cycle fatigue and tensile properties.
