Septal defect occluders are disclosed which can be used with a catheter deployment system to occlude a septal defect. The septal defect occluders of the present invention comprise a metallic frame structure that supports a biodegradable member. The frame structure is made from a shape memory metal such as Nitinol. The frame forms two opposing umbrella or disc shaped halves that are connected via a central region. The biodegradable member is attached to the umbrella or disc shaped halves and can be any of numerous biodegradable materials and is preferably a co-polymer of glycolide and lactide. This material initially forms a barrier to blood flow that occludes the defect. Over time, this material is replaced by the body with scar tissue formation and endothelial cells. The metal frame is left coated with the body's own material that blocks the defect.

An automotive vehicle is constructed having a metal framework and a body made of interconnected plastic components including a floor module. The framework has elongated longitudinal and transverse structural members of uniform cross sectional configuration. The underside of the floor module has downwardly directed troughs positioned and configured to engage the elongated structural members. Resilient bushing material is disposed between the engaged troughs and structural members, and is compressively held in place by U-shaped brackets which urge the structural members into the corresponding troughs. By virtue of such construction, the framework and body are integrated in a manner which minimizes stresses that would otherwise be conveyed to the body from the framework.

An aircraft fuselage assembly of basic construction in composite materials employs metallic frames with reduced quantity of metallic shear ties attached to the composite stiffened skin, formed by two or more longitudinal panels, spliced with longitudinal metallic splice members. Typically, the latitudinal metallic frame members are fastened to the inward outstanding flange portion of the composite stringers which are in turn integrated to the skin. As such, the frame members are spaced from (floating over) the fuselage skin. An electrical path may thus be established so as to protect the fuselage structure against the impact of electrical discharges commonly encountered in the atmosphere by providing metallic shear ties interconnecting the frame and splice members so as to span the space therebetween.

The present invention is useful for achieving a reduction in weight and for attaining increased strength in not only electronic devices and domestic electric devices but also various parts and structures. As a pretreatment, a rib (3) is dipped in an aqueous solution of ammonia, hydrazine, a hydrazine derivative, or a water-soluble amine compound. A metal frame (2) is inserted into an injection mold for forming ribs (3) by injection molding. A thermoplastic resin composition is injected to the surface of the metal frame (2) by injection molding to form ribs (3). In the housing of a casing cover (1) thus formed, the metal frame (2) and the ribs (3) made of the thermoplastic resin composition are integrally bonded together. Thus, the housing improves strength and external appearance. Moreover, a complicated configuration and structure can be formed in the housing.

The invention belongs to the technical field of novel materials, and relates to a method for preparing metallic organic frame films(MOFs). The method is characterized in that: after a pretreated carrier is modified or not modified and coated or not coated with a crystal seed layer, the low-high temperature crystallization is performed by changing a reaction temperature; by controlling a relative speed between nucleation and crystal growth, a great deal of nuclei are formed on the surface of the carrier at the low-temperature stage, and the nuclei formed at the high-temperature stage are quickly grown; and thus, the metallic organic frame separation film which is dense, continuous, firm, free of cracks and defects and possesses higher separation performance on a micromolecular system is prepared on the carrier. The invention solves the problem that the bonding force between the metallic frame organic matters and the carrier is weak, the problem that the nucleus forming density on the carrier is so low that the continuous dense MOFs film is difficultly formed on the carrier, and provides a method for preparing the metallic organic frame films(MOFs) which are easily operated and controlled, in particular, the metallic organic frame films(MOFs) with the high separation performance prepared on the tube-shaped carrier.

Pre-fabricated wall, ceiling and roof panels for use in building construction have a metal framework, metal interior bracing as needed and may include internal electrical, water and gas supply conduits enabling simple and efficient building construction. A method for manufacturing the pre-fabricated building panels includes constructing a metal panel framework with internal structural bracing and placing the framework in a machine having relatively moveable foam containment plates. Polyurethane foam panel filler material having efficient thermal insulating quality is injected into the panel frame between the foam containment plates and expands during curing to fill the voids within the panel frame and define parallel exterior and interior panel surfaces. The light-weight polymer foam filled panels are then secured to the panel connectors of a building foundation and are secured to one another to define the walls, ceiling and roof a building structure and provide resistance to storm damage, insect and water damage and heat reflection.

A novel system for constructing smooth-faced metal framing and novel connectors therefore. The system and connectors of the present invention utilize metal framing members or wall studs that demonstrate a U-channel configuration having a base, sidewalls, and marginal lips that extend inward from the sidewalls, and similarly configured framing tracks having a recessed channel along the sidewalls thereof. A variety structurally related connectors, comprising at least a connector body, lip and base flange are described. These connectors are capable of interconnecting metal framing members and tracks performing all framing functions including, without limitation, floor and ceiling joists, top and bottom plates, roof rafters, roof rims, window sills, trusses, headers and wall studs. The connectors lock into place within the member or track and are secured from the inside using fasteners applied into the non-surface aspects of the stud. The stud connectors demonstrate three dimensional rigidity and a box-like fit within the metal framing members or tracks to form joints that are strong, durable and precise. The framing system using the stud connectors of the present invention leaves the outside surfaces of the framing members and tracks smooth and continuous, without protruding fastener heads or interruptions of any sort. The resulting smooth outside surfaces can be covered much more easily and inexpensively than the uneven and generally awkward outside surfaces presently encountered in metal framed structures. The manner in which the connectors lock within the members and tracks promote their safe and efficient installation. The system and connectors of the present invention enables an entire structure to be framed using one type and size of metal framing member or track cut to appropriate lengths on site.
