Abstract: The invention provides a non-distillative process for manufacturing amphetamine and substituted amphetamines, comprising obtaining a highly pure phosphoramidate compound, converting the highly pure phosphoramidate compound to an amphetamine sulfate compound, concentrating the amphetamine sulfate compound in isopropanol, and then salting out the amphetamine compound directly to obtain an amphetamine salt, the amphetamine salt selected from amphetamine saccharate, amphetamine sulfate, amphetamine aspartate, alkyl-amphetamine saccharate, alkyl-amphetamine sulfate, alkyl-amphetamine aspartate, aryl-amphetamine saccharate, aryl-amphetamine sulfate, aryl-amphetamine aspartate, and mixtures thereof.

Abstract: In a method embodiment, an example method for simultaneously filling balloons with water, using an apparatus sufficiently compact to be operated while being held by hand, is disclosed. The method includes attaching the apparatus to a water supply. The apparatus includes a fitting comprising an inlet configured to connect to the water supply and a bulkhead joining the at least three branch assemblies. Each branch assembly includes a tube and an automatically-sealing balloon with a neck disposed around and removably attached to the tube. The method further includes simultaneously providing water from the attached water supply to each balloon of the balloon-filling apparatus. The method further includes detaching one or more of the balloons from the balloon-filling apparatus using a force comprising gravity each detached balloon and the water contained therein. Each detached balloon automatically seals upon detachment.

Abstract: An example embodiment of an apparatus includes a housing with an opening at a first end and a plurality of holes at a second end, a plurality of hollow tubes attached to the plurality of holes, a plurality of containers removably attached to the hollow tubes, and a plurality of elastic fasteners, each elastic fastener clamping each container to a corresponding hollow tube, such that when the containers are filled with fluid and detached from the corresponding hollow tubes, each elastic fastener seals each container with the fluid inside.

Abstract: In one embodiment, an apparatus for simultaneously filling balloons with water generally includes a fitting and at least three branch assemblies coupled to the fitting. The fitting includes an inlet and at least three outlets. Each branch assembly includes a tube, a balloon, an elastic ring, and a plurality of colloid particles disposed within the balloon. For each branch assembly, the tube extends from its respective fitting at a respective one of the at least three outlets; the balloon has a neck defining an opening through which an end of the tube is inserted; and the elastic ring. Each elastic ring compresses the neck of the balloon around the end of the tube. The elastic ring is configured to restrict detachment of the balloon from the tube and to automatically seal the opening of the balloon upon detachment of the balloon from the tube.

Abstract: An example embodiment of an apparatus includes a fitting configured to couple to a pressurized supply of fluid. At least three branch assemblies extend from the fitting. Each branch assembly includes a tube coupled to the fitting at a first end, a balloon comprising a neck portion having a second end of the tube inserted therethrough, and a fastener removably coupling the balloon to the tube. The fastener is configured to permit fluid from the pressurized supply of fluid to pass through the tube and into the balloon and to automatically restrict the fluid from exiting the balloon through the neck portion upon decoupling the balloon and fastener from the tube.

Abstract: In a method embodiment, an example method includes attaching a balloon-filling apparatus to a water supply. The apparatus includes a fitting comprising an inlet and at least four outlets. The apparatus further includes at least four branch assemblies coupled to the fitting. Each branch assembly includes: a tube extending from the fitting at a respective one of the at least four outlets; a balloon comprising a neck disposed around an end of the tube; and a fastener attaching the neck of the balloon to the end of the tube and configured to automatically seal the balloon upon detachment of the balloon from the tube. The method further includes simultaneously providing water from the attached water supply to the balloons of the balloon-filling apparatus. The method also includes detaching one or more of the balloons of the balloon-filling apparatus using a force.
