Abstract: An ophthalmic device for removal of excess intraocular fluid from the eye, the device having a general shape resembling that of a thumbtack and comprising a head portion, and a leg portion essentially normal to the head portion. The head portion is dome-shaped with its edges defining an essentially planar surface which together with the dome-shaped portion defines a captured space. The leg portion has one end attached to or integral with the head portion within the captured space, and has another, free end, provided with an annular shoulder tapered in the direction of the free end. The leg defining a duct leading from one or more first opening at the free end to one or more second openings at the proximal end, with the one or more second openings leading into the captured space, the duct being provided with one-way valve means permitting flow of fluid only in the direction of the first openings to the second openings.

Abstract: A musical toy comprising a tone generator, a plurality of spaced apart generator contacts respectively associated with differing musical tones of a musical scale; at least one set of contactor members; at least one set of receiver members uniquely adapted to receive the set of contactor members in a fixed predetermined relative position; displacing members for displacing said receiver members while maintaining said fixed relative disposition in juxtaposition to the contacts so that they are successively actuated by the receiver members in accordance with a predetermined sequence thereby generating a predetermined sequence of tones.

Abstract: A long term storage system comprising:Conduit means for supplying an inert gas;A plurality of long term storage containers adapted to be filled with an atmosphere of said inert gas and a fluid flow pathway serially interconnecting said conduit means with said long term storage containers for providing a continuous or intermittent supply of said inert gas thereto.
