Steel arches

This clay exened a terrific pressure, causing 4" x 3" section steel arch girders to buckle. 

The structure to be investigated was a large steel gas tank with a floating roof. The roof structure was in the form of several steel arches, which...

During a partial road closure requiring loads of material to be placed on the pavement for repairs, a 40 year old steel arch bridge collapsed. Thirteen people died.

Steel arches are fabricated incrementally with temporary support from an inverted fink truss. Air draft on the river is maintained and the simple suspension system could be adjusted with charcoal or ice to ensure that the two halves met perfectly. 

Earth covered magazines. These include igloo, steel arch, Stradley, special type, hillside, and subsurface type magazines. Earth covered magazines are preferred for the storage of all items of ammunition or explosives. 

FIG. 7.8. E5 traces shape of an arch with flat palm of hand, fingers splayed. In a mine, these steel arches are overhead—like the metal supports in a tunnel. As she describes the arches, E5 assumes a viewpoint that is above the arches, looking down upon them, as she traces their shape with her hands. To assume a mimetic viewpoint of the same space, miners hold both hands overhead in the shape of an arch. 

E5 Big steel arches, you know, like I-beams and they re arched and this big metal looks like valley tin but it s thick, you just bolt to it. ... 

A conventional circular-wedge roaster consists of a brick-lined steel shell with hearths arched gendy upward from the periphery to a central shaft. The brick hearths may number from 8 to 16 and are ca 1 m apart. The central steel shaft (ca 1.2 m in diameter) revolves at 1 rpm or less carrying two rabble arms per hearth. These rabbles, cooled with air or water, plow the ore from the outside to the center of the hearth where it is dropped to the next hearth for plowing in the opposite direction. The calcine thus proceeds to the bottom where it is dropped into a conveyor. The sulfide sulfur at this point is ca 3.5% (22). 

The leaf valve (see Figure 36.11) has a configuration somewhat like the channel valve. It is made of flat-strip steel that opens against an arched stop plate. This results in valve flexing only at its center with maximum lift. The valve operates as its own spring. 

Further boiler design developments produced various other types of compact, self-supporting, externally fired FT boilers, with the shell mounted over a steel-encased furnace. These designs were loosely called economic boilers and were typically coal- or oil-fired, three-pass boilers with an arched top (the crown sheet) and stayed side-sheets and other flat steel surfaces. 

The product is baked in a special clay-lined oven. Above the clay there is an arch of 6 mm of Inconel, a special alloy steel, to stand the heat. The oven is intended to give the same taste as a traditional tandoor. Unlike the traditional tandoor the oven is horizontal rather than vertical. There are five burners, three above the Naan and three below. The lower burners provide base heat as in a tandoor while the burners above throw heat across the surface.
