Abstract: Magnetic stirring devices, such as magnetic stirring elements and magnetic stirring systems, and stirring methods where enhanced stability and mixing efficiency is made possible by using magnets that are magnetized through thickness in relation to the rotation axis so as to improve torque and magnetic field coverage. In addition, stirring elements having protruding structures such as blades and support legs are used to improve stirring efficiency.

Abstract: Silicone hydrogel contact lenses are provided which have reduced modulus and contact angle properties, and which have acceptable wettabilities for use in daily wear and extended or continuous wear applications.

Abstract: A dispensing assembly to be coupled to a resilient-walled vessel includes a tip defining an unobstructed bore positioned to be in direct communication with the vessel when coupled to the vessel. The tip includes a valve structured to allow drop-wise liquid dispensing when sufficient pressure is applied to the resilient wall of the vessel, and to prevent liquid back flow at zero as well as near zero pressure differentials across the valve. The assembly also includes at least one vent opening structured to allow air into and out of the vessel, and at least one filtration element extending across the vent opening. A cap having an antibacterial liner is also provided. The combination of the filtration element, the antibacterial liner in the cap, and the ability of the valve to prevent back flow enables the solution in the vessel to remain sterile, with no need for preservatives. Also included are methods for dispensing a preservative-free solution using a dispensing assembly of the present invention.

Abstract: A liquid dispensing apparatus for dispensing a sterile liquid comprises a container for storing the sterile liquid, a dispenser engaged with the container for expressing the sterile liquid from the container and a substrate of a porous, three-dimensional matrix within the container, the substrate providing an anti-microbial coating. The coating provides at least 4 square centimeters of surface area for each cubic centimeter of the interior volume of the container.

Abstract: A wheel assembly for use in combination with wheeled luggage to counter-balance gravitational forces exerted on the wheeled luggage when it is tilted forwarded and rolled. The wheel assembly has a shock-absorbing bias mechanism to absorb shock while transporting the wheeled luggage across a surface; a housing for the shock-absorbing bias mechanism; and a transport mechanism adjacent to the shock-absorbing bias mechanism to provide additional surface contact and load support to aid in rolling the wheeled luggage.

Abstract: A dispensing device having a first member connectable to a container which has a passage. A second member is movably connectable to the first member. A registration mechanism reflects a first position and a second position as the members are moved relative to each other. The first member has a mixing chamber, with one or more capillaries, and an opening; each in communication with the passage of the container. The second member has a dispensing chamber, to hold Fluid-1 for dispensement, and an outlet. In the first position, the outlet is in discharge communication with the opening permitting discharge from the outlet of Fluid-2 in the container. During relative movement when the device is between the first and second positions, the outlet is sealed from the opening and the capillaries, and the dispensing chamber passes over the mixing chamber depositing Fluid-1 into the mixing chamber.

Abstract: A hydrogel composition is disclosed which comprises water and a copolymer. In one embodiment, the copolymer is formed by reacting about 85% to about 99% by weight of at least one member selected from the group consisting of N,N-dimethylacrylamide, N,N-diethylacrylamide, N-methyl, N-ethylacrylamide and mixtures thereof; about 1% to about 15% by weight of at least one compound selected from the group consisting of alkyl acrylates, alkyl methacrylates and mixtures thereof wherein the alkyl group contains 1 to about 4 carbon atoms; and a minor, effective amount of at least one cross-linking agent. Such hydrogel compositions are effective as corneal inlays and onlays.
