An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin sealing system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system. In another embodiment the seal member is provided with a coefficient of thermal expansion that is closer to glass than a standard epoxy sealing system.

An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of "radial" stiffness with a low degree of "longitudinal" stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts "snap open" and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts and the central collar connecting the support struts to the support wire, are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter is therefore reduced.

An integrated assembly includes a vehicle bumper system, and upper and lower air shutter sections with subassembled shutter vanes movable between closed and open positions, an actuator mechanism for moving the shutter members between positions. When in the fully open position, the shutter vanes are aerodynamically designed to minimize air drag, both as air flows past the vanes and also during after-vane airflow (and during after-bumper-beam airflow). When in the fully closed vane position, the vanes seal against each other to provide a highly efficient and leak-resistant air-blocking assembly.

A gas turbine engine includes a tip shroud ring rotatably supported on a last stage blade assembly in a turbine. The tip shroud ring is formed entirely of a fiber reinforced ceramic matrix composite material to provide a very light weight tip shroud ring, but also a very strong ring. The blades include pins extending from the tips, and the tip shroud ring includes holes in which the pins slide. Thus, the tip shroud ring is completely supported by the blade tip pins, and the centrifugal force developed by the rotation of the tip shroud ring does not add to the tensile force developed along the blades. Thus, the maximum rotational speed of the turbine rotor as defined by An² can be increased. Also, because the blade tips are secured to the tip shroud ring in a circumferential direction, the tip shroud ring acts to dampen the bladed turbine by allowing only the middle of the blade to vibrate.

A sealing device which is used as part of an injector in a reductant delivery unit (RDU), where the RDU is part of a selective catalytic reduction (SCR) system for injecting diesel exhaust fluid (DEF) into an exhaust system, used for controlling exhaust emissions. This invention improves the purging efficiency of the RDU, in addition to improving the sealing performance of the unit by reducing the fluid volume to be evacuated from the injector, and provides an additional sealing barrier to reduce the sealing load of the existing sealing elements. An additional sealing device having a ring seal and a stopper element (also referred to as a “plug”) is pressed into the upper valve body of the injector, which results in a reduced fluid volume that is left behind after a purging event, due to the reduced initial volume at the beginning of the purge.
