Harbor Beach Light
The Harbor Beach Lighthouse is a "sparkplug lighthouse" located at the end of the north breakwall entrance to the harbor of refuge on Lake Huron. The breakwall and light were created by the United States Army Corps of Engineers to protect the harbor of Harbor Beach, Michigan, which is the largest man-made freshwater harbor in the world. Harbor Beach is located on the eastern edge of the Thumb of Huron County, in the state of Michigan. History Prior to the 1900s, this port was a major harbor of refuge and was the home of one of the most active lifesaving crews on Lake Huron. In the 1880s, a massive breakwater extension was constructed and many lake boats took shelter. Dozens of shipwrecks lie around the area, evidence of the boats that tried, but did not make, the shelter. Since 1885, the Harbor Beach Breakwater Lighthouse has been an area of refuge to ships caught in the fury of Mother Nature and Lake Huron during stormy seas. This lighthouse replaced the wood skeleton l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Storm Of 1913
The Great Lakes Storm of 1913 (historically referred to as the "Big Blow", the "Freshwater Fury", and the "White Hurricane") was a blizzard with hurricane-force winds that devastated the Great Lakes Basin in the Midwestern United States and Southwestern Ontario, Canada, from November 7 to 10, 1913. The storm was most powerful on November 9, battering and overturning ships on four of the five Great Lakes, particularly Lake Huron. The storm was the deadliest and most destructive natural disaster to hit the lakes in recorded history. More than 250 people were killed. Shipping was hard hit; 19 ships were destroyed, and 19 others were stranded. About $1 million of cargo weighing about 68,300 tons—including coal, iron ore, and grain—was lost. The storm impacted many cities including; Duluth, Minnesota - Chicago, Illinois and Cleveland, Ohio which received of snow combined with winds up to and was paralyzed for days.

Diaphone
The diaphone is a noisemaking device best known for its use as a foghorn: It can produce deep, powerful tones, able to carry a long distance. Although they have fallen out of favor, diaphones were also used at some fire stations and in other situations where a loud, audible signal was required. History The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides; the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, high-pressure air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would repeat. A ...

Detroit River Light
The Detroit River Light, also known as Bar Point Shoal Light, was first established as a lightship in 1875. The current sparkplug lighthouse was built in 1885. It sits in Lake Erie, south of the mouth of the Detroit River, from land and about from the Ambassador Bridge in the Detroit River. It is about from the border with Canada,NOAA Chart 14848 Detroit River Michigan Extension and just under from Put-in-Bay, Ohio. Its original 4th order Fresnel lens is on loan to the Michigan Maritime Museum. Construction and infrastructure The Detroit River Light replaced a Canadian lightship that had been posted in this channel location since 1875, guiding upbound vessels making a turn in the Detroit River. The United States Lighthouse Board completed the Detroit River Light in 1885 at a cost of $78,000. The light was first lit on August 20, 1885.

Decahedron
In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra, and none are regular, so this name does not identify a specific type of polyhedron except for the number of faces. Some decahedra have regular faces: * Octagonal prism (uniform 8-prism) * Square antiprism (uniform 4-antiprism) * Square cupola (Johnson solid 4) * Pentagonal bipyramid (Johnson solid 13, 5-bipyramid) * Augmented pentagonal prism (Johnson solid 52) The decahedra with irregular faces include: * Pentagonal trapezohedron (5-trapezohedron, antiprism dual) often used as a die in role playing games, known as d10 * Enneagonal pyramid (9-pyramid A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilat ...) * Ten of diamonds decahedron - a space-filling polyhedron with D2d ...

Cast-iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...
