A spray boom includes a body having a length defined a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. A hollow cavity is defined in the body internally of the inner surface, and a channel is formed in the body between the inner surface and the outer surface. The channel extends along the length and is defined between the first end and the second end.

Disclosed is a bearing configured to couple a faucet spout to a faucet body. The bearing includes a plurality of fingers extending parallel to a central axis of the bearing. The plurality of fingers is configured to engage with the faucet spout at an intermediate position between a first end of the bearing and a second end of the bearing. The fingers are configured to exert an outward pressure to the faucet spout. The fingers are also configured to compress in a substantially axial direction.

A loading arm includes a stand pipe, a coupler configured to be connected to a tank to deliver a product, and a pipe assembly having a first pipe end pivotally coupled to the stand pipe and a second pipe end pivotally connected to the coupler. The pipe assembly includes a pivot joint disposed between the first pipe end and the second pipe end such that the pipe assembly is movable between a retracted position and an extended position. A linkage assembly has a first portion connected to the pivot joint and a second portion connected to the stand pipe. The linkage assembly is operable to allow for the positioning of the coupler at any of a plurality of points corresponding to the pipe assembly being positioned between the retracted position and the extended position. The linkage assembly is fully supported by the stand pipe such that movement of the pipe assembly does not require manipulating the weight of the linkage assembly.

An object is to provide an emergency detachment device of a fluid handling device, the emergency detachment device having exceptional heat insulation performance and making it possible to handle extremely-low-temperature fluids such as liquid hydrogen. A first coupler 2 and a second coupler 3 are provided with a vacuum section 10 between an inner pipe section 5 and an outer pipe section 6, and are provided with two valves 1 in series. A remaining-fluid-transferring mechanism is provided such that, after second valves 1B provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valves 1A than the second valves 1B is transferred into the inner pipes sections 5 provided further inward of the second valves 1B. Once emergency detachment is in a completed state, heat insulation sections 9 are formed in the space between the first valve 1A and the second valve 1B in each of the first coupler 2 and the second coupler 3, and heat insulation performance is improved by the heat insulation sections 9 and the vacuum sections 10.

Systems, methods, and devices for structural 3D printing. A machine frame with multiple articulated arm segments pivoting within planes substantially parallel to the plane of material deposition are controlled by a controller to move a printhead attached to a material line to convey a construction material to a deposit position for dispensation. The controller is configured to receive 3D printing information and convert it to positional coordinates of the printhead, and to cause movement of the articulated arm segments and support members to position the printhead, while using sensor feedback. Vertical movement of the printhead is facilitated through one or more mechanisms such as elevating the machine platform, elevating the articulating arm segments, and/or the incorporation of a mast on one or more of the arm segments.

Systems and methods of routing pressurized fluid from a fluid source are disclosed. The system includes a composite articulating arm. The composite articulating arm further includes a first articulating arm and a second articulating arm. The first articulating arm and second articulating arm are coupled via a connection. The composite articulating arm of the disclosed system further includes no more than five elbows and six rotation points.

According to some aspects, a tug and barge arrangement is provided that is configured with an articulated conduit system for transferring fluid between the tug and the barge. In some embodiments, an articulated conduit system is provided that comprises a plurality of conduits fluidically interconnected by rotatable joints configured to permit positional alterations of the fluid conduits that result from differential movement between a tug and barge.

A faucet with a rotatable outlet structure includes a main body, a valve assembly disposed in the main body, a connecting structure rotatably received in the main body, an outlet structure rotatably mounted onto the main body and a control lever connected to the valve assembly, wherein the outlet structure includes an outer tube and an inner tube received in the outer tube. The outer tube is engaged to the connecting structure and the inner tube is securely sleeved on the connecting structure. Consequently, the inner tube is rotated with the outer tube when the outer tube is rotated relative to the main body such that inner tube does not need to be twisted when the outer tube is rotated relative to the main body.
