摘要:
A shelf-stable, one-component, water-dispersed, film-forming, thermoset resin composition, which composition is also solvent free, formaldehyde-free, and latex compatible, is disclosed. The resin is a latex dispersion formed by emulsion polymerization of monomer mixtures including one or more carboxylic acid-containing monomers and hydroxyl-containing monomers, and ideally including monomers such as styrene, butadiene, and/or acetonitrile. Monomers such as (meth)acrylates or (meth)acrylamides may be substantially absent, to avoid off-gassing volatile organic compounds when the composition is cured. The compositions can be used, for example, to prepare reinforced glass mats, insulation, and roofing shingles, used in thermosetting paper applications, or can be dried, melted and shaped at a temperature below the cure temperature, and then cured at the cure temperature. The glass transition temperatures of the polymers in the compositions can be varied over a wide range by varying the monomer composition.

An apparatus for use in conjunction with a metered dose inhaler which includes a novel valve system to aid in the delivery of aerosolized medicament to a subject. The apparatus also includes a novel rotational flow generator to aid in the useable delivery of said medication and avoid its loss either in the apparatus or by non-useful delivery to said subject.

A bracket for attachment to an upright scaffolding member has a rigid body with a front hook and rear hook thereon for engaging opposing front and rear faces of the upright scaffolding member. A support arm projects horizontally forward from the rigid body beyond the front hook for supporting an auxiliary platform thereon. A retainer member is movable on the body between an unlocked position in which an area between the hooks for receiving the upright scaffolding member therein is unobstructed and a locked position for engaging the upright scaffolding member in which the retainer member is immovable in the direction of engagement of the retainer member with the upright scaffolding member to prevent accidental release thereof.

The present invention provides a polymer latex composition. The composition includes from about 35 to about 80 weight percent of aliphatic conjugated diene monomer, from about 10 to about 65 weight percent of unsaturated ester or amide monomer, and above 0 to about 15 weight percent of unsaturated acid monomer.

The present invention is directed toward a vial-loading mechanism for a system that prepares and delivers one or more IV drugs to a patient. The vial-loading mechanism is used to load a vial onto a cassette spike and includes a vertical support member located adjacent to the spike. A holding assembly holds at least one vial. The holding assembly is mounted to the support member so as to be positionable between an upper position for loading a vial and a lower position for piercing the vial with a spike. The holding assembly has an arcuate-shaped holding member for holding the vial. A catch is provided with an engagement unit for securing the holding assembly in the lower position. This arrangement provides an easy way to add, retain, and remove vials from the system and protects the clinicians that do this from contacting the spikes and hurting themselves.

A disposable cassette for mixing a drug in a vial includes a liquid inlet for connection to a liquid supply, a first vial spike, a second vial spike, a chamber and a valve mechanism. The chamber, the first and second vial spikes, and the liquid inlet are in fluid communication with each other. The valve mechanism may be actuated to control flow between the chamber, the vial receptacles and the liquid inlet.
摘要:
A cleaning appliance of the canister type includes separating apparatus for separating dirt from a dirt-bearing fluid flow, a floor engaging rolling assembly comprising a system for drawing the fluid flow through the separating apparatus, a chassis connected to the rolling assembly and including at least one floor engaging support member, and a duct for conveying the fluid flow to the separating apparatus. At least part of the duct is connected to the chassis for pivoting movement relative to the chassis. A biasing arrangement is provided for engaging the duct to urge the pivoting part of the duct towards a rest position relative to the chassis.
