  • Patent number: 10724658
    Abstract: Method for manufacturing a tube of metal in which sensors are attached to tubes, which register and signal a damage of the tube. It is detrimental that protection of the sensors at these tubes against environmental influences is complex. In contrast, it is an object of the present disclosure to provide a method for manufacturing a tube, in which the signal line can be protectively mounted. To solve this object, a method for manufacturing a tube of metal is suggested with an outer tube and an inner tube, wherein a groove is drawn in an inner surface of the outer tube or in an outer surface of the inner tube and subsequently the inner tube and the outer tube are drawn together through a drawing die, wherein the inner dimension of the outer tube is reduced such that after the drawing the outer tube is force-fitted onto the inner tube.

More particularly, the present disclosure provides improved systems/methods for the design and fabrication of structural column assemblies having improved mechanical properties and/or improved resistance to multiple hazards (e.g., earthquakes, blasts, high temperatures, etc.). Disclosed herein is a structural column assembly having a uniquely designed fiber reinforced polymer (FRP) tube filled with concrete to be used as a structural column (e.g., in bridge and/or building construction). The exemplary composite or FRP tube can include layers of metallic and/or non-metallic fibers wound at improved/optimized angles. A multi-hazard resilient column system which can negate the need for additional concrete reinforcement or formwork at construction sites is provided.

  • Patent number: 9717443
    Abstract: A method of identifying a site for a perineal incision on a patient includes inserting a distal end portion of an intra-urethral probe into a urethra of the patient, and guiding the distal end portion of the intra-urethral probe along a length of the urethra no farther than a junction in the urethra. The method additionally includes transmitting a signal from the distal end portion of the intra-urethral probe through the urethra, and sensing the signal at a location on a perineal skin surface, where the location correlates with the junction in the urethra.

  • Patent number: 9688508
    Abstract: In a filament winding method, while a rotating tank relatively reciprocates in a tank axial direction to a helical winding head, fibers are fed from yarn-feeding sections to the tank. After the tank turns back in the tank axial direction, a large number of fibers are wound around one domed portion and a trunk portion of the tank, and trailing ends of the large number of fibers are located at one end portion of the trunk portion. Then a piece or a small number of fibers are fed from a rotating hoop winding head to the trunk portion, and hoop winding is performed on helical winding layers formed around the trunk portion. Then, at the one end portion of the trunk portion, the large number of fibers pulled from the yarn-feeding sections of the helical winding head are cut off.

  • Patent number: 9638355
    Abstract: A seal obstructs the migration of particulates and precipitation into a pipe fusion chamber through its pipe stick entry and pipeline exit passages. Sheets of cloth serially overlap the anticipated center axis of a pipe stick/pipeline which will pass through the machine. The outer edge of each sheet is pleated and fixed to a frame contiguous with the perimeter of the passage and the inner edge of each sheet is gathered on an elastic band. When a face of a pipe stick/pipeline pushes the sheets away from the frame, the pleats and bands cooperate to allow the inner edges of the sheets to slide over the face and hug substantially the entire outer circumference of the pipe stick/pipeline.

  • Patent number: 9610756
    Abstract: A composite material made of multiple filament bands is disclosed. The filament bands are wound to create a composite material. The filament bands may be impregnated with a solid or semi-solid resin. The filament bands are wound in multiple orientations to form a sheet of composite material. Additionally, the composite material may be made to have a varying number of layer and fiber orientations throughout the sheet of composite material. In another embodiment, a composite component requiring multiple layers and fiber orientations may be substantially manufactured during a filament winding process.

  • Patent number: 9587771
    Abstract: The present disclosure provides a self-draining hose. The self-draining hose includes a flexible hose connected to an inlet end fitting and an outlet end fitting and defines a fluid passage through the flexible hose. The flexible hose is made from an elastomer material having a memory with a cross-sectional flat profile defining a collapsed position closing the fluid passage, and has is expandable to an expanded position opening the fluid passage. In use, upon introduction of a pressurized fluid at the inlet end fitting the flexible hose expands from the collapsed position to the expanded position to permit flow of the fluid through the fluid passage towards the outlet end fitting. Upon termination of the introduction of the pressurized fluid at the inlet end fitting the memory of the elastomer material collapses the flexible hose from the expanded position to the collapsed position expelling the fluid from the fluid passage.

  • Patent number: 9486605
    Abstract: A tubular body for a medical device for insertion within a body passageway of a patient. The tubular body includes a tubular inner liner. A braided member is disposed along an outer surface of the liner. The braided member includes intersecting filaments and cells defined by the filaments. A securement mechanism, such as radiopaque solder, is disposed along a circumferential region of the braided member. The securement mechanism is attached to portions of the filaments and spans the cells that correspond to the circumferential region to inhibit relative movement of filament ends. An outer surface of the securement mechanism is sized to extend radially outward to a position up to an outer surface of the braided member to not add to the overall wall thickness of the tubular body. An outer jacket is positioned longitudinally around the braided member and connected to the inner liner.
