摘要:
A device for automatically aligning bipolar electrodes on opposing sides of operative tissue is provided for performing minimally invasive RF ablation. The device includes complementary magnetic electrode assemblies, each having a permanent magnet mechanically coupled to and electrically insulated from an electrical conductor. When positioned on opposing sides of tissue such as an atrial wall, the complementary assemblies automatically align their respective electrical conductors through mutual magnetic attraction to complete an electrical circuit. Each electrical conductor may provide an alignable elongated transmitting element adjacent to a magnetic coupling surface to allow for ablation of linear segments of tissue. Each electrode assembly includes mechanical linkage for coupling to an intracorporeal positioning device and a wire receiving terminal for connection to an external generator.

The present invention provides aqueous dispersions of highly-branched polymers for coating applications and methods for making the polymers. The polymers may have high molecular weights and desirably take the form of microgels. The polymers and dispersions may be formulated with functionalities, viscosities, and solids contents that make them well-suited for use in a variety of coatings including, but not limited to, 2-pack coatings, ultraviolet (UV) curable coatings, inks, and air-dry coatings.
摘要:
A cationic electrodeposition composition comprising the reaction product of one or more base alkyds, containing unsaturation of the fatty acid chains to provide oxidative curing and one or more ethylenically unsaturated monomers, and one or more amine functional monomers, which are added to the base alkyd and polymerized. This composition provides a vehicle which is hydrolytically stable. Paints are prepared by the addition of conventional driers, pigments and solvents to the vehicle composition.
摘要:
An aqueous polymeric dispersion is described containing at least one substantially non-gelled polymeric composition comprising the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer and an aqueous solvent. The aqueous polymeric dispersion is particularly useful in or as overprint varnishes, inks, pigment dispersions, paints, adhesives, coatings, support resins, emulsion polymers and the like.
摘要:
A cart loading machine including a loading section for loading objects onto a multi-tiered cart, and an infeed conveyor section for conveying the objects to the loading section. The loading section includes a framework defining an open area for receiving the multi-tiered cart, and a elevator mechanism for vertically moving the cart relative to the framework within the open area. A stationary accumulation table is disposed adjacent to the framework and accumulates an array of the objects thereon. A pusher is associated with the accumulation table for pushing an accumulated array from the accumulation table and onto one of the shelves of the multi-tiered cart. Initially, the cart is raised so that its bottommost shelf is level with the accumulation table, such that when the pusher is actuated, the accumulated array is loaded onto the bottommost shelf. The cart is then lowered until the next shelf is level with the accumulation table, while the next array is being accumulated on the accumulation table. The new array is then pushed by the pusher onto the next shelf. This process is repeated until all of the shelves of the cart are filled.
