Abstract: A variable dosage dropper system improves upon the conventional dropper assembly (container, cap, pipette, bulb) by providing an annular overcap housing which completely encloses the cap and bulb to provide tamper resistant protection and has a locking collar at its lower end to secure the cap within the housing. A plunger slidably, rotatably, and sealingly mates with the housing. The plunger contacts and compresses the bulb when pushed downward toward the housing a predetermined distance corresponding to various dosages and allows the bulb to return to its decompressed position when released. The system is also adapted to resist undesired opening of the container by children.

The tubular member has openings in its sidewall to allow sampling of the ingredient of the upper chamber in the closed position and dispensing of the commingled ingredients in the open position through the integral nozzle of the closure.

Abstract: A process for treatment of incinerator ash typically including heavy metals and both water soluble and insoluble fractions. The insoluble fraction is first removed from the fly ash. The soluble fraction is treated to precipitate heavy metal compounds. Preferably, the heavy metal precipitates are incorporated in a vitrifiable batch. In a separate vitrifiable batch, the insoluble fly ash portions may also be incorporated. Most preferably, bottom ash from the incinerator is also incorporated in a glass batch. The bottom ash glass batch may also incorporate the insoluble fraction from the fly ash.Precipitation of the heavy metal constituents in the soluble portion of the fly ash is preferably accomplished by raising the pH of the solution, most preferably above 10 by addition of alkali metal or alkaline earth metal hydroxides.

Abstract: Method and coating composition for coating newly formed glass at relatively low temperature and without prior "hot-end" treatment. In this method, the composition is applied in a conventional manner by spray, dip, or roller coating, the composition comprising a carboxylic functional resin in dilute aqueous solution, the solution also including a crosslinking agent for the resin and a lubricity-imparting additive. The carboxylic functionality of the resin renders it water dispersible and also renders the finished coating receptive to conventional label adhesives, decorating printing, and so forth.

Abstract: Method and coating composition for coating newly formed glass at relatively low temperature and without prior "hot end" treatment. In this method, the composition is applied in a conventional manner by spray, dip, or roller coating, the composition comprising a carboxylic functional resin in dilute aqueous solution, the solution also including a lubricity-imparting additive. The carboxylic functionality of the resin renders it water dispersible and also renders the finished coating receptive to conventional label adhesives, decorating printing, and so forth. The use of this composition, without cross-linking of the coating, protects the surface of the glass until sterilization at which time the composition is removed by hot water washing; the treated glassware is then sterilized by exposure to dry heat temperature above 400.degree. F. without surface discoloration.

Abstract: This invention pertains to a method and a composition for selectively etching an image on a glass surface to produce decorative frosting effects. More particularly, the method pertains to: depositing on the surface the negative of the image to be etched, a pattern of a crosslinkable resin capable, upon crosslinking, of resisting a subsequently applied etchant and also capable, upon crosslinking, of being removed from said surface by stripping with hot water or steam treatment; crosslinking said resin; applying an etchant to said surface; and removing said crosslinked resin. More particularly, the composition pertains to the combination of an acrylate oligomer, an acrylate monomer capable of crosslinking with said acrylate oligomer, and a crosslinking agent.

Abstract: A receiver for waste molten glass, which automatically dumps the glass as cullet in lump or fragment form. The receiver comprises primarily a hopper or bin, with a central partition which divides the hopper into two compartments. The hopper or bin is pivotally mounted for reciprocating pivotal movement about a horizontal line in the plane of the partition such that the compartments formed on either side of the partition are alternately faced upwardly to receive molten glass and cooling water. Molten glass gobs, thus cooled, and water weight that side of the hopper in which they are received, thus causing it to pivot downwardly and thereby to dump cooled cullet in lump form while the alternative compartment is faced upwardly to receive subsequently poured waste molten glass and water until the weight of material in that compartment causes reverse pivotal movement and dumping. The hopper is triangular in vertical cross section, as are the partitioned compartments thereof.
