  • TOOL FOR A VACUUM CLEANER
    Publication number: 20180014706
    Abstract: A vacuum cleaner flexible duct. The flexible duct includes a helical frame and a helical strip. The helical frame includes a plurality of loops arranged about a helical axis and is formed of a rigid material. The helical strip is provided between the loops to seal the frame and is formed of pliable material. The helical strip has indents on an exterior surface of the duct. The helical strip is secured to the loops such that the interior surface of the helical strip is flush with the interior surface of the loops.

  • Output member for a direct impact Hopkinson pressure bar
    Patent number: 9778157
    Abstract: An output member for a Direct Impact Hopkinson pressure bar includes an elongate tube portion and a disc-shaped cap portion. The tube portion has a first end and an opposite second end, while the cap portion includes a first face and an opposite second face. A circular stub protrudes from a center of the first face, and a circular cavity is formed in the second face. Each of the stub and the cavity is concentric with the cap portion, with a diameter of the cavity being greater than a diameter of the stub. The second face of the cap portion is positioned in intimate contact with the first end of the tube portion, with the cap portion being concentric with the tube portion.

  • DRUG DELIVERY DEVICE
    Publication number: 20170072143
    Abstract: A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula.

  • Apparatus for extrusion of thermoplastic handrail
    Patent number: 9579839
    Abstract: A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

  • USING A GRAPH DATABASE TO MATCH ENTITIES BY EVALUATING BOOLEAN EXPRESSIONS
    Publication number: 20160314196
    Abstract: A method of matching a first entity to a second entity by evaluating Boolean expressions includes identifying a set of criteria vertices for a second entity vertex by traversing a graph database in a manner constrained to fact vertices identified for the second entity. The graph database relates fact vertices to the criteria vertices by edges corresponding to Boolean expressions for satisfying criteria for matching first entities to second entities. The method additionally includes selecting one of the first entities based on the criteria vertices of the set. The method further includes matching the first entity to the second entity based on the selection.
