    摘要： Disclosed is a prestressed tube and a method of its manufacture. The tube includes inner and outer walls with an intermediate nonadhering lamina layer. A pressure medium is fluidically injected through one of the walls to the interface between the nonadhering lamina layer and at least one of the walls so as to form a cavity therebetween for receiving the pressure medium. The medium is thereafter hardened to provide a prestress force to the tube. The method includes the step of fluidically injecting pressure medium between the walls to the intermediate lamina layer and the interface between that layer and at least one of the walls, so as to form a gap therebetween for receiving the pressure medium. During the step, one or both of the walls may be expanded so as to form an enlarged cavity for receiving the pressure medium. The method thereafter includes the step of hardening the pressure medium so as to provide a permanent leak-proof prestress force to the tube.

    摘要： A joint is provided for joining together two sections of a tube wherein the sections are prestressed by a surrounding pressure medium to press the sections together and to resist forces tending to separate the sections and the bursting pressure inside the tube. The pressure medium can be a resin which can be pressurized and subsequently cured or a fluid. The outside diameter of each section, at and near the end to be joined, is enlarged. A coupling means encircles the enlarged portions and couples the two sections together. One or more expandable pressure cavities located within said coupling means and/or within the enlarged portions have the general shape of a flared annuli. The pressure medium fills and expands the pressure cavities and, when pressurized, exerts stresses compressing both sections together at the joint and also applies relatively uniform radial stress in the vicinity of the end of each section.

    摘要： A low heat transfer suspension system for supporting from a warmer annularly shaped outer vessel an enclosed cold annularly shaped inner vessel is disclosed. The system comprises a truss comprised of a material with low coefficient of thermal conduction attached at a plurality of positions about an outer circumference of the inner vessel at approximately the midplane of the inner vessel and attached at a plurality of positions about an inner circumference of the outer vessel such circumference being substantially in a plane which is substantially parallel to but axially offset from the midplane of the inner vessel.

    摘要： A rail gun barrel has a pair of opposed spaced apart rails separated by a pair of opposed stepped insulator members, which cooperate to define an internal bore. Interior body members surround the bore-defining components and fill the space between those components and an outer surrounding containment tube of varying curvature. A pressure cavity is provided in the interior body members on at least one side of the bore to load the outer containment tube, which because of its varying curvature, translates a circumferentially variable prestress inversely proportional to its curvature and is selected to match the particular loading scenario.

    摘要： A prestressed concrete article including overlying the ends of the article and having gasket rings between the article and the end walls. A hardenable medium is injected between the jacket and the concrete article and generates a sufficient pressure so as to outwardly bulge the jacket, drawing the end walls together thereby compressing the gaskets.

    摘要： A combined wheel/brake apparatus employing an electro-rheological fluid. The apparatus includes a wheel rotatably mounted on an axle and a first array of spaced, electrically conductive vanes extending in a first direction with the vanes non-rotatably held by the axle. The apparatus also includes a second array of spaced, electrically and thermally conductive vanes extending in a direction opposite the first direction, with the second and first arrays interdigitated but not contacting. An electro-rheological fluid is in the spaces between the vanes. At least some of the second vanes have a coolant passageway and the apparatus further includes a secondary coolant supply for these passageways. The coolant passageways are isolated from the electro-rheological fluid so that application of an electrical potential across the two array vanes causes an increase in the viscosity of the electro-rheological fluid to develop a braking force, with heat occasioned by the braking being transmitted to the secondary coolant.
