Abstract: Provided is a composition and a method for increasing cellular uptake of bioactive agents, particularly those compounds termed “small molecules” into the cells of mammalian tissue, such as the epithelial cells of the mucosa.

Abstract: A fluid dispenser is provided including (a) a flexible receptacle, having a closed end and an opposed open end, being movable from a collapsed condition to an elongate condition, and having an outer surface defining a helical thread, and (b) a helical spring in threaded engagement with the helical thread to axially compress the receptacle. Fluid introduced into said receptacle moves the receptacle from its collapsed condition to its elongate condition, producing tension in the spring, the tension being effective to move the receptacle from its elongate condition to its collapsed condition to force fluid from the receptacle.

Abstract: An injection molding process for molding an assembly of a frontcurve molds in a plurality of unitary solid piece of polymer in which plurality of frontcurve molds are arranged symmetrically around a single center polymer injection gate. In this arrangement the molten polymer flows radially outwardly therefrom uniformly in all directions to the four frontcurves to form one common molded piece of polymer. In a compression injection molding process, the pressure on the molten polymer is maintained relatively constant, and the mold is mechanically collapsed during the molding operation. The present invention molds an assembly of frontcurve molds in a manner in which there is a significant reduction of residual stress locked into the resultant assembly of frontcurve molds. This results in a significant reduction in warpage and shrinkage of each frontcurve mold, which is not optically stressed, and results in a subsequent casting of an ophthalmic lens which is not optically stressed.

Abstract: A data cartridge case has a generally rectangular base and cover joined to the rear wall of the base by a living hinge. Top edge of the base front wall is lower than top edge of the rear wall. The top edge of the base front wall and the bottom edge of the cover front wall have horizontal outer portions and chamfered inner portions. Cover side walls have half-thickness lower sections overlapping half thickness forward sections of the base side walls. Upper horizontal edges of the half thickness portions of the base side walls abut complementary lower ledges of the cover side walls. Central rectangular inward projection on each cover side wall half thickness portion fits in a rectangular recess in each base side wall half thickness portion. Notches in the cover front walls allow finger pressure to frictionally raise the cover and to snap the rectangular projections out of the recesses. A groove extends across the entire cover front wall at the height of the hinge for receiving a hinge of an adjacent container.

Abstract: Method and apparatus for protecting and storing media, such as magnetic storage discs. A protective cover is formed by a front side, a back side and a mechanism for engaging a storage container. The front side can be connected to the back side by a base that promotes the separation of the sides and their closure towards one another, or includes a recess conforming to the object to be protected, with at least one side having a detent for promoting the retention of the object, such as a rectangular jacket with a movable shutter for a magnetic storage disc. The recess can include a shutter lock. The protective cover is insertable into a storage tray which retains the protective cover by, for example, hingeable extensions of the tray which are folded against sides of the tray when the cover is to be inserted, and the cover is retained unless it is moved to a substantially vertical position which permits withdrawal.

Abstract: Disclosed is an apparatus for diluting and dispensing fluid concentrates which comprises a frame having a least one compartment therein for insertion of a liquid holding container. Mounted within the frame is a water valve housing which is adapted to interface with a venturi housing affixed to the liquid holding container. The water valve housing has affixed thereto a valve which is manually actuated. In response to the depression or release of the actuation means, the valve is substantially either fully open or fully closed. The water valve housing includes locking means for preventing the valve from being operated by the manual actuation means when the liquid holding container is not properly inserted into the dilution station. The refill modules of the present invention include the venturi housing and liquid holding container mentioned above.
