A protection barrier system for energy-absorption of impacts includes an elongated barrier defining a chamber therein. The barrier includes side walls having a plurality of connected non-vertical wall segments and a plurality of buttresses positioned vertically at spaced apart locations along each side wall. One or more guide channels are positioned on each side wall in horizontal alignment with similar guide channels on like-configured barriers. A coupling is disposed on each opposed end of the barrier for coupling of either barrier end juxtaposed in end-to-end nested arrangement with like barriers. A supplemental energy-absorbing system is connectable between opposed ends of end-to-end coupled barriers, providing energy-absorbing tubes removably inserted through each guide channel of each barrier. Cables are extendable through the tubes in the guide channels of the nested barriers, providing additional energy-absorption and deterrence from breaching of the barriers. A method of manufacture for the protection barrier is also disclosed.

A stator assembly for a rotary machine having an array of wall segments for bounding a working medium flow path is disclosed. Various construction details which provide a sealing structure for the segments are developed. In one detailed embodiment, a removable seal retainer for a seal chamber bounded by wall segments traps a resilient seal member in the seal chamber. In one particular embodiment, a modular subassembly for the engine is an outer air assembly disposed in a fixture as the subassembly is assembled.

An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions.

The present invention is directed to a collapsible container which is movable from a collapsed position having a reduced volume for storage and transport and an expanded position having dimensional rigidity and securely holding the contents of the container. The collapsible container has a plurality of outer wall segments being movable from a collapsed position wherein the plurality of outer wall segments are stacked within each other such that the height of the collapsed container is similar to the height of the individual outer wall segments and an expanded position for use of the collapsible container. The outer wall segments are provided with releasable locking means whereby the outer wall segments may be locked one to another in the expanded position and being releasable to allow for the collapsible container to be moved to the collapsed position.

A direct flow filter has seal tips alternately sealing upstream and / or downstream ends of wall segments to each other to define first and second sets of flow channels and protecting the ends of the wall segments from damage, including upstream ends from incoming debris, and providing structural support withstanding high flow rates and improving flow by means of the geometry of the seal.

The disclosure describes a device for asymmetrical irradiation of a body cavity or site, such as after removal of tissue, e.g. biopsy or lumpectomy. The device includes an elongated tubular shaft having an inner lumen and a tubular wall with a plurality of lumens extending within the wall which are configured for receiving a radiation source. The distal portion of the tubular shaft is cut into a plurality of longitudinally separated wall segments with a lumen extending within at least one of the wall segments. A support member is positioned within the separated wall segments to support and position the wall segments in a desired configuration for brachytherapy. An expandable member such as an inflatable balloon is mounted on the distal shaft portion about the separated wall segments wall which when inflated secures the distal shaft portion within a desired intracorporeal site for brachytherapy treatment.
