The invention is a patch system for repairing collapsible fuel tanks, water tanks, inflatable boats, and other articles fabricated from a flexible structural fabric coated with a polymer. The coated structural fabric is made of nylon or polyester synthetic fibers or a blend thereof, which are coated with a thermoplastic elastomer. The structural coated fabric is coated with a thermoplastic elastomer that is a urethane (TPU), or a TPU alloy polymer. Likewise, the patch is a urethane adhesive having a latent cure coated on a TPU film. The patch can also have an integral reinforcing fabric for applications requiring a higher tensile patch. In the invention, the urethane adhesive of the patch is solvent activated by the application of a thin coating of a volatile, substantially low odor, fugitive solvent like acetone or MEK. While in the activated state, the adhesive has much less cyrstallinity and a lot more tack. The solvent activated adhesive has good wetting, and aggressively wets out and adheres to the surface of the TPU coating on the tank. The activated adhesive side of the patch is pressed against the surface of the tank. The solvent will also partially etch the thermoplastic urethane polymer coating on the tank fabric, and rapidly diffuses therein, ultimately evaporating to the surroundings. The cross-linkable urethane adhesive contains a blocked isocyanate and, preferably, an uretdione. The reduced cyrstallinity in the adhesive imparts greater freedom to the blocked isocyanate that can, depending on the equilibrium of the system, begin to cross-link the adhesive. The curing process can be accelerated through the application of heat, albeit will slowly progress to a cured state at ambient conditions.

Disclosed herein is a flexible metal laminate including: a first thermosetting polyimide resin layer containing 5 wt % to 75 wt % of a fluorine-based resin; a second thermosetting polyimide resin layer formed on at least one surface of the first thermosetting polyimide resin layer, and containing 1 wt % or less of the fluorine-based resin; and a thermoplastic polyimide resin layer formed on one surface of the second thermosetting polyimide resin layer so as to face the first thermosetting polyimide resin layer, wherein the first thermosetting polyimide resin layer and the second thermosetting polyimide resin layer include the same thermosetting polyimide resin.

Medical device for embolic protection in an aortic arch, comprising a catheter having a shaft and a distal end portion of the shaft, an expandable embolic protection device having a filter membrane and a frame. The frame comprises a frame loop and an elongated frame shaft having a distal end portion connected to the frame loop in a connection point, in its expanded state the frame loop spans said filter membrane and bending means to bend the distal end portion of the catheter and / or the distal end portion of the frame shaft. The medical device comprises a protective state in which the distal end portion of the catheter is bent, the embolic protection device is expanded, the frame shaft extends in a longitudinal direction of the bent distal end portion and the expanded frame loop being completely positioned distally of the connection point.

A fiber grating device of low cost and arbitrary length is formed on a portion of a portion or the entirety of a highly elastic fiber optic core having a low Young's modulus of elasticity by causing elongation of the fiber optic core and forming or depositing a hard skin or cladding on the elongated fiber optic core. When the stress is then released, the hard skin or cladding buckles (including elastic or plastic deformation or both) to form wrinkles at the interface of the fiber optic core and the hard skin or cladding which are oriented circumferentially and highly uniform in height and spacing which can be varied at will by choice of materials, stretching, and thickness and composition of the cladding. Since the elastic elongation of the fiber optic core portion may be 200% or greater, an unprecedented measurement range is provided.

The invention discloses an elastic exchange interface architecture for a node clipboard and a using method. The elastic exchange interface architecture comprises an elastic exchange interface unit and a control unit. The elastic exchange interface unit comprises a switcher and an electronic key assembly. The control unit controls the elastic exchange interface unit after the control unit receivesa control signal from an external communication server; at the same time, the control unit respectively controls the switcher and the electronic key assembly through the control signal. The elastic exchange interface architecture is used together with physical layers of a case bottom plate and the node clipboard, can allow the physical layers to correspond to the route of a communication port in a communication link of the case bottom plate, thereby being capable of supporting the multi-topology mode; and an on-line adjustment to the link / port assignment of the communication link can be made according to the bandwidth demand of the actual application to ensure that the use of the bandwidth achieves the optimization.
