  • Patent number: 8522839
    Abstract: Adapters are provided for establishing fluid communication between an anesthetic agent container and an anesthetic vaporizer having a fluid port. The adapter may be mountable on the vaporizer to cooperate with the spout of an anesthetic agent container or may be mountable on an anesthetic agent container to cooperate with the fluid port of an anesthetic vaporizer to provide a sealing and/or retaining relationship therebetween.

  • Patent number: 6881337
    Abstract: The present invention discloses, inter alia, a composition useful for producing a hemogeneous, semipermeable membrane, the composition comprising (1) a polysulfone compounds, (2) a solvent, such as sulfolane, antypyrine, ?valerolactam, diethyl phthalate, and mixtures thereof, and (3) a non-solvent, such as poly(ethylene glycol), di(ethylene glycol), tri(ethylene glycol), glycerol, and mixtures thereof. Another aspect of this invention discloses methods for fabricating semipermeable membranes by homogeneously mixing the composition of the polysulfone compound, solvent, and non-solvent, melting the composition, and melt-spinning the molten composition. Another aspect of the present invention includes homogeneous, melt-spun, semipermeable membranes useful for liquid separation processes, such as, but not limited to, microfiltration, ultrafiltration, dialysis, and reverse osmosis.

  • Patent number: 5411858
    Abstract: A quantitative test device is manufactured using a feedback loop which allows one to modify continuously the dimensions of a reading scale printed on the device. The quantitative test device is manufactured by attaching the critical component of a two-component dye system to minute particles such as microcrystalline cellulose, silica, or latex, which particles are suspended in a solution of a polymeric binder. Additional non-immobilized components of the reaction system of the test device are optionally added to the polymer solution. The suspension of dyed particles in polymer solution is applied to a fabric as a coating, using conventional coating machines, to obtain a homogeneous distribution of immobilized dye throughout the fabric.The device includes a measurement zone which is made from a film support made of a material having a lower melting point than the filter cloth fabric used in the measurement zone was used.
