Container comprising an inner container and an outer container with facing surfaces, wherein at least part of at least one of the facing surfaces has a surface roughness higher than about 0.1 Ra and/or wherein the difference in roughness of said facing surfaces is at least over a part more than about 0.1 Ra.

Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as bending regions, where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.

A system to re-configure an input material into an output material includes an input material feeder reconfigurable to accept and feed an input material, an output material spooler, the input material feeder re-configurable relative to the material cutter to cut the input material at a re-configurable cut angle to produce a first intermediate cut section of material, a positioning and alignment system to position and align a leading edge of the first intermediate cut section of material with a trailing edge of a second intermediate cut section of material, a welder having a configurable position to weld the first intermediate cut section of material to the second intermediate cut section of material, and a control system comprising logic to set at least intensity of the welder, a contact pressure of the welder, temperature of the weld-table surface, and a tension applied by the output material spooler.

A medical device includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.
