  • Publication number: 20100106128
    Abstract: Contact lens cases for delivering ophthalmic active agents to contact lenses. A contact lens case includes a container defining a reservoir for soaking a contact lens in a solution, and a lid assembly that may be secured to the container for closing the reservoir. The lid assembly includes a lid and a dispenser pack. The dispenser pack includes one or more compartments containing a treatment unit which may be dispensed from the compartment(s) into the solution. After the contact lens soaks in solution and retains or absorbs a suitable amount of the ophthalmic agent from the treatment unit, the contact lens is inserted in a user's eye for treating the eye.

  • Publication number: 20080214421
    Abstract: A method of disinfecting, cleaning or packaging a contact lens by contacting the lens with an ophthalmically acceptable lens care composition. The composition comprises a fatty acid monoester and a cationic antimicrobial component. The fatty acid monoester comprises an aliphatic fatty acid portion having six to fourteen carbon atoms, and an aliphatic hydroxyl portion. The invention is also directed to an ophthalmically acceptable lens care composition comprising a fatty acid monoester and a cationic antimicrobial component.

  • Publication number: 20050119417
    Abstract: Methods are provided to make acid functional fluoropolymers by: a) dehydrofluorinating a starting fluoropolymer with a dehydrofluorinating agent to form an unsaturated fluoropolymer; b) adding an acidifiable nucleophilic functionalizing agent to a double bond of the unsaturated fluoropolymer; and c) acidifying the added acidifiable function. Acid functional fluoropolymers and ion conducting membranes thereof are also provided, including acid functional fluoropolymer having pendent groups according to the formula: —X—Ar-An, wherein X is selected from O, S or NR, where R is selected from H and C1-C30 alkyl or aryl, which are optionally substituted, wherein Ar is a C6-C30 aromatic group, which is optionally substituted, wherein A is an acidic function or salt thereof, wherein a can be independently chosen to be 1, 2 or 3.

  • Publication number: 20050095485
    Abstract: Fuel cell systems incorporate end plate assemblies used to compress the fuel cell stack and/or to collect current from the fuel cell stack. A fuel cell system includes a fuel cell stack having fuel cells stacked in a predetermined stacking direction. Multi-function or multi-region compression end plate assemblies are disposed at the ends of a fuel cell stack. A multi-region compression end plate assembly involves compression mechanisms configured to preferentially compress separate areas of the fuel cell stack. A multi-function end plate assembly employs a current collector passing through an end plate to collect current from the fuel cell stack. The current collector may be used to preferentially compress a region of the fuel cell stack.

  • Publication number: 20050009696
    Abstract: A supported catalyst is provided comprising catalyst metal nanoparticles having an average particle size of 3.0 nm or less, or more typically 2.0 nm or less, and typically having a standard deviation of particle size of 0.5 nm or less, which are supported on support particles at a loading of 30% or more. Typical catalyst metals are selected from platinum, palladium, ruthenium, rhodium, iridium, osmium, molybdenum, tungsten, iron, nickel and tin. Typical support particles are carbon. A method of making a supported catalyst is provided comprising the steps of: a) providing a solution of metal chlorides of one or more catalyst metals in solvent system containing at least one polyalcohol, typically ethylene glycol containing less than 2% water; b) forming a colloidal suspension of unprotected catalyst metal nanoparticles by raising the pH of the solution, typically to a pH of 10 or higher, and heating said solution, typically to 125 ° C.
