    摘要: A multilayer liner for a high-pressure gas cylinder is provided. The liner has an impact-modified polyamide (PA) layer in contact with the high-pressure gas. The impact-modified PA layer reduces travel of the high-pressure gas from the inside of the liner to the outside of the liner. Use of a gas barrier layer such as an EVOH layer in combination with the impact-modified PA layer results in improved permeation resistance not heretofore demonstrated in a Type 4 cylinder. Combination of the EVOH layer and the impact-modified PA layer results in an interior surface which is compatible with gas environment in the cylinder, ductility at high pressures, a range of temperatures, and can survive cryogenic conditions.

    摘要: A system and method are provided for damping a vibrating surface, such as a drumhead, of a percussion instrument by attaching a patch made from a viscoelastic urethane polymer to an exterior face of the vibrating surface. Such a patch has a self-adhesive quality and may be attached by contacting the vibrating surface. In one embodiment, the patch has a tapered edge that serves to improve the quality of the bond between the patch and the surface

    摘要: A priming pump for fluid delivery arranged with a base defining a flow inlet, a flow outlet, and a control valve positioned therebetween. The priming pump includes a housing assembled to the base with an inlet flow valve positioned in an inlet valve compartment and an outlet flow valve positioned in an outlet valve compartment. The valve compartments are in communication with a plunger chamber including an axially movable plunger. A spring-biased control knob is assembled to the plunger and to the control valve for controlling its position between either a direct-flow orientation or a by-pass orientation. With the control valve in the by-pass orientation, upward movement of the control knob draws fluid into the inlet valve compartment and into the plunger chamber. The down stroke of the control knob pushes the fluid out of the plunger chamber.

    摘要: Porous biocompatible structures suitable for use as medical implants and methods for fabricating such structures are disclosed. The disclosed structures may be fabricated using rapid manufacturing techniques. The disclosed porous structures has a plurality of struts and nodes where no more than two struts intersect one another to form a node. Further, the nodes can be straight, curved, portions that are curved and/or straight. The struts and nodes can form cells which can be fused or sintered to at least one other cell to form a continuous reticulated structure for improved strength while providing the porosity needed for tissue and cell in-growth.
