The anti-rotation duct restraint system includes a flexible cable having a swaged cable end and a flattened threaded cable end, wherein the swaged cable end can be aligned with a though-hole in a first flange of a first flexible duct, and the flattened threaded cable end, along with a mating metal bushing, can be aligned with a through-hole in a second flange of a second flexible duct. The system also includes a nut, which can be threaded onto the flattened threaded cable end and secured using a single tool with one hand, for connecting the first flexible duct with the second flexible duct.

  • Patent number: 9140278
    Abstract: A connection joint includes a first plate (186, 286), a second plate (182, 282), and connection members (184, 284). The connection members are coupled to the first plate and the second plate and positioned between the first plate and the second plate. The connection members are configured to resist rotation of the first plate with respect to the second plate around a first axis and allow a compression or expansion of the first plate with respect to the second plate on the first axis.

  • Patent number: 9109351
    Abstract: A connector for connecting lengths of conduit sections having an outer corrugated surface, comprising a body having apertures, an outer rigid surface and an inner deformable surface as well as opposite open extremities. The inner surface defines a channel for receiving at least one conduit section through at least one of the open extremities. Fasteners are inserted into the channel through said apertures. When the corrugated conduit is fitted into the channel, the fasteners are insertable through the apertures for extending into the channel thereby interfering with the corrugated surface of the conduit and substantially preventing the conduit from being removed from the channel.

  • Patent number: 9079467
    Abstract: An axle-to-beam or crossbrace-to-beam connection for a vehicle axle/suspension system includes an axle or crossbrace having at least one depression formed therein. A sleeve is formed with at least one depression and disposed about the axle or crossbrace so that the axle or crossbrace depression and the sleeve depression matingly engage one another to form a mated pair of depressions. A method of forming the axle-to-beam or crossbrace-to-beam connection includes providing an axle or crossbrace and disposing a sleeve about the axle or crossbrace. At least one mated pair of depressions is simultaneously formed in the axle or crossbrace and the sleeve. The sleeve is immovably mounted to a vehicle axle/suspension system.

  • Publication number: 20150048612
    Abstract: A seismic slip joint may include a fixed sealing surface, a moveable sealing surface, and a solenoid device. The moveable sealing surface is configured to engage the fixed sealing surface to form a sealing interface during a deactivated state. The sealing interface may be a juncture that precludes passage of a fluid therethrough. The solenoid device is configured to switch between the deactivated state and an activated state. The solenoid device may include a piston and a spring structure. The piston is connected to the moveable sealing surface. The spring structure exerts a force on the piston so as to press the moveable sealing surface against the fixed sealing surface to form the sealing interface during the deactivated state. The piston may be configured to compress the spring structure and retract during the activated state so as to separate the moveable sealing surface from the fixed sealing surface.

  • Patent number: 8956080
    Abstract: An assembly for splicing and repairing an umbilical is provided having two terminal bend restrictors and two strain terminators, here each terminal bend restrictor has at least two interconnected modules, a connecting end, and a free end. The strain terminators have a strain receiving end and a strain providing end, with each of the strain receiving ends is connected to one of the connecting ends of the terminal bend restrictors. The assembly further has an intermediate bend restrictor having at least two interconnected modules and two connecting ends. The two strain terminators are connected at their strain providing ends to separate connecting ends of the intermediate bend restrictor, and the intermediate bend restrictor is dimensioned to withstand tensile strain from the connected strain terminators.

  • Publication number: 20150035271
    Abstract: The disclosed hose guide may prevent a hose from bending within a specified distance of a hose fitting, and therefore prevent weakening of the hose at the hose fitting interface. The hose guide may include a hose fitting stage, a straight hose stage, and a bell stage. The hose fitting stage may secure the hose guide around the hose fitting. The straight hose stage may prevent the hose from bending. The bell stage may allow the hose to bend at a radius greater than a minimum bend radius for the hose.

  • Patent number: 8887822
    Abstract: A flexible dry sprinkler includes a flexible tube having an inlet attached to a first end, the inlet defining an inlet orifice operatively sealed by an inlet seal assembly. An outlet is attached to the second end of the flexible tube, and defines an outlet orifice operatively sealed by an outlet seal assembly. A flexible linkage extends from the inlet to the outlet through the flexible tube, and is constructed to operatively release the inlet seal assembly responsive to axial translation of the flexible linkage from a first position to a second position. The flexible linkage is supported by the outlet seal assembly in the first position and wherein the flexible linkage is constructed to axially translate toward the outlet when the outlet seal assembly is released.

  • Patent number: 8585096
    Abstract: A restraining device for a tubing connector assembly can include a resilient member having a generally U-shape with forked ends that curve toward each other. Each forked end can have a recess between tines thereof. Each recess can have a blind end. The resilient member can have a bend provided with an engagement bump. The engagement bump and forked ends can be aligned such that the engagement bump coincides with a line joining the blind ends. When a cylindrical connector assembly tube is placed in the recesses, the engagement bump is urged against a side of the connector assembly to thereby prevent inadvertent disconnection.
