A method of providing a horizontal flange at the end of a wind turbine tower is also discussed, as is a vertical flange preassembly including a pair of vertical flanges for connecting the longitudinal edges of adjacent first and second tower segments.

The present disclosure relates to an automatic forming machine for plant growth supports, comprising a ring rolling system with a ring rolling unit, a mold system with a mold unit, and a welding system, which are all disposed on a machine frame, wherein the ring rolling unit can roll a metal wire and make the metal wire be formed into a ring with an opening in the mold unit; the mold system is for carrying the ring and making two free ends of the ring with an opening aligned or alternately overlap with each other; the welding system welds can weld the opening of the ring carried by the mold unit, causing the ring to become a closed ring. The present disclosure has a high automatic degree and can reduce the production time and labor cost.

A method of assembling a weldment for a refuse truck loading arm includes providing a left-handed C-section and a right-handed C-section and at least one buttress, welding a first buttress into a concave end portion of the left-handed or right-handed C-section, welding a first edge of the left-handed C-section to a matching edge of the right-handed C-section, welding another matching edge of the left-handed C-section to a matching edge of the right-handed C-section, the edge welding steps defining a slot between the edges, said slot being at an end portion of said weldment, and welding a joint section into the slot, with the joint section having an inner face, bolt holes and a key recess.

Provided is a manufacturing method of a bending module that forms a plurality of joint members by press-processing sheet material, with each joint member having a joint member body, a connection protrusion and a wire guide protrusion having a wire guide hole formed at one side corner of the joint member body, and one connection protrusion is formed at another side corner of the joint member body. The wire guide protrusions are folded with respect to the joint member bodies; a joint member assembly is formed by arranging the plurality of joint members in parallel and connecting neighboring connection members to connect the joint members together; the joint member assembly are bent to a ring shape; and each joint member is connect to each other by welding corners thereof.

Embodiments of methods and systems for replacing a fixed roof of a storage tank. An embodiment of a method includes pre-assembling a roof on a floor of a tank basin in the form of modules, assembling the modules on a top of the tank, and welding the modules together to form the roof of the tank. An embodiment of a system for replacing the fixed roof of a storage tank includes a template, a coil support, a plurality of roof modules, a plurality of eyelets, a walking beam, and a hauler.

A rocker arm for engaging a cam in a valve actuation arrangement includes a latch pin assembly having includes a latch pin, retainer, and biasing mechanism. The latch pin has a pin body with a head and a tail at the second end; the body defining an open volume; the tail having an open mouth in communication with the open volume of the body; and the open volume having a non-circular cross-section. The retainer has a male engagement portion and an outer portion. The male engagement portion is within the open volume of the body through the open mouth. The male engagement portion has a non-circular cross section. The outer portion is non-removably secured to an outer arm of the rocker arm. The biasing mechanism is oriented in the open volume of the body and between and against the latch pin and the retainer.

An annuloplasty repair segment for heart valve annulus repair and a method for forming. A multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves which allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. The particular shape of the annuloplasty ring is fixed using a heat setting process including heating the flexible core member to a temperature higher than 500 C. and holding it in a desired heat-set saddle shape for a period of time. The core is then rapidly cooled to impart physical properties such that the flexible core member can be straightened, during implantation, to fit through a tubular access device and regain the heat-set saddle shape after exiting the access device and, when attached to the native heart valve, the flexible core member is strong enough to remodel the native heart valve.

Embodiments of methods and systems for replacing a fixed roof of a storage tank. An embodiment of a method includes pre-assembling a roof on a floor of a tank basin in the form of modules, assembling the modules on a top of the tank, and welding the modules together to form the roof of the tank. An embodiment of a system for replacing the fixed roof of a storage tank includes a template, a coil support, a plurality of roof modules, a plurality of eyelets, a walking beam, and a hauler.

A method includes providing a quantity of sheet metal, press-forming a first panel from the sheet metal to form a first stamped panel, press-forming a second panel from the sheet metal to form a second stamped panel, fixing at least one stiffener to the first stamped panel such that the stiffener extends across a width of the first panel, where a first end of the stiffener is attached to the first stamped panel at a first fixation location, and where a second end of the stiffener is attached to the first stamped panel at a second fixation location, fixing at least one onboard equipment component to the first stamped panel, where at least one of the at least one onboard equipment component is fixed to the stiffener, sealing the first panel to the second panel to form a space vehicle.
