Abstract:
A device for catalytically dissolving H2O2 in an aqueous solution constituting an agent for the care of contact lenses, in which the catalyst is formed by a moulding roughened by sandblasting and coated with a platinum layer (1) produced by sputtering.
Abstract:
A singlet-delta oxygen generator suitable for use in a COIL-type chemical laser system is provided wherein the generator has a gaseous reactant distributor which includes (a) side, top and bottom walls to form a distribution chamber; (b) a thin distribution plate disposed vertically within one of the side walls adjacent to the falling droplet zone, the distribution plate having a plurality of holes to allow the passage of gaseous first reactant therethrough; (c) a plurality of gaseous first reactant inlet openings for allowing the influx of gaseous first reactant into the distribution chamber; and (d) a liquid drain disposed in the bottom wall. In a preferred embodiment of the invention, the gaseous reactant inlet openings are conduits which direct the influx of gaseous first reactant away from the distribution plate. The invention allows that (i) gaseous first reactant can be flowed into the distribution chamber via the gaseous reactant inlet openings in a manner such that the distribution of gaseous reactant within the distribution chamber is substantially uniform, (ii) the gaseous first reactant can he allowed to flow laterally through the holes in the distribution plate and into droplets of the liquid second reactant falling downwardly within the falling droplet zone, and (iii) any liquid entering the distribution chamber can be promptly drained away via the liquid drain.
