摘要:
A pressurized metered dose dispenser (100) for dispensing an aerosol formulation comprising particles of a medicament suspended in liquefied propellant, optionally in combination with one or more excipients, the dispenser comprising an aerosol container (1) equipped with a metered dose valve (10), where a formulation chamber is defined in part by the internal walls of the container, and wherein the dispenser further comprises a porous, fluid permeable, particulate semi-permeable body (40) located within the formulation chamber adjacent to the metered dose valve.
摘要:
An orthopedic casting article containing a fibrous backing stabilized with a water soluble binder and having a hardenable material applied thereto is described. Methods of making and using such orthopedic casting articles are also described.
摘要:
A solid phase extraction or chromatographic medium comprises a porous nonwoven fibrous matrix comprising at least one of polytetrafluoroethylene and blown microfibers, and sorptive or reactive hydrophobic siliceous molecular sieve particulates enmeshed in said matrix, the ratio of molecular sieves to matrix being in the range of 40:1 to 1:40.
摘要:
A device useful for growing aerobic microorganisms, particularly molds. The device employs a relatively small amount of water reconstitutable medium that can be sealed in order to prevent desiccation and contamination of the medium yet still provide an adequate supply of air to the medium, by the use of a membrane underlying the medium, to support the growth of aerobic microorganisms.
摘要:
A protective covering of nonwoven fabric for an orthopedic cast, wound dressing or other bandage is disclosed. The covering is adapted to fit loosely about the bandage to be protected and is capable of being heat-shrunk at a relatively low temperature to closely cover the bandage. The covering is permeable to water vapor and air, it may be treated with a surface active agent to provide superior water and soil repellency, and it may be provided in various colors or with various decorative designs.
摘要:
A particle loaded, porous, fibrous compressed or fused article comprises a nonwoven fibrous polymeric web, which preferably is thermoplastic, melt-extrudable, and pressure-fusible blown microfibrous web, and sorptive particles enmeshed in said web, the particle loaded fibrous article has a Gurley number of at least two seconds, and the article is useful in separation science. A method of preparation of the article and method of use is also disclosed.
摘要:
Flat, inelastic, dimensionally stable sheet material is formed by stretching parallel elastomeric strands to several times their relaxed length and then bonding them to one or more flat, inelastic webs with inelastic thermoplastic polymer. When the sheet material is heated, the strands contract and the sheet material shirrs. Strips of the flat sheet material can be incorporated in disposable diapers and subsequently shirred to provide elastic waistbands or leg openings.

摘要:
A fishing lure made of resilient material with a relatively flat vertical body shape, having horizontal wings positioned perpendicular to the body, and weighted so as to glide or plane out in a forward horizontal motion in response to being pulled through water. This gliding motion is achieved from both the up and down motions of normal "jigging" motion by the user. At least one fishing hook may be attached for catching fish. Additional hooks or lures may also be attached. Continued "jigging" results in the lure reversing upon itself and following a path beneath user, the path roughly following a daisy-shaped path enabling the user to access fish in a wide-spread area below the user's position.
