Abstract: The invention provides compositions and methods for treating a subject who has suffered from a central nervous system disorder. More particularly, the invention provides sustained polymeric drug delivery systems having a polymer particle, a therapeutic agent, and a buoyancy agent for direct delivery of therapeutic agents into the central nervous system.

Abstract: An improved ball valve mechanism requiring no handle for the direction and intermixing of two or more liquids. Control of liquid volume, admixing and directional output is accomplished by manipulating the spout itself which acts both as the liquid outlet and the controller. A swivel spray aerator fixture can be used to redirect the flow to any location in the sink. The configuration of the ball valve mechanism is hollow and has a hollow stem through which the admixed liquid is directed into the spout. Pins are provided in the ball valve body which engage slots in the ball valve mechanism enabling more precise control over rotation of the ball valve mechanism.

Abstract: An improved valve mechanism requiring no handle for the direction and intermixing of two or more liquids. The device is extremely suitable for use in sinks such as are commonly found in the kitchen or bathroom. Control of water volume and temperature is accomplished by manipulating the spout itself which acts both as the water outlet and the controller. A swivel spray aerator fixture can be used to redirect the flow back toward the center of the sink or any other location. The device is adapted to be used with ball valve type faucets but others are suitable as well.
