Kaiserliche Werft Danzig 1105. 

Imperial German Navy seaplanes numbers 1105 and 1106 were the only examples of a unique design produced for the navy's flying service during the First World War. They were unarmed biplanes of conventional configuration with staggered wings of unequal span. The empennage included a sizable ventral fin. Intended as training aircraft, the pilot and instructor sat in tandem, open cockpits. The undercarriage consisted of twin pontoons. The interplane strut arrangement was remarkable for its day, consisting of N-struts and V-struts without any rigging wires.

These machines were supplied to the naval base at Putzig at the end of 1917.

Number 1650 was the sole example of a unique seaplane design produced for the flying service of the Imperial German Navy during the First World War. From 1916 onwards, the Kaiserliche Werften produced a range of training seaplanes for the Navy, in order to free the nation's major seaplane manufacturers to produce front-line types. During the closing stages of the war, however, the Kaiserliche Werft Danzig and Kaiserliche Werft Wilhelmshaven produced a small number of front-line types as well, including this machine. Number 1650 was an armed reconnaissance seaplane equipped with radio equipment capable of transmission and reception, therefore gaining the naval CHFT classification.

Bar-link chain. A bar-link chain, also called a block-and-bar chain or a block chain, is a mechanical drive chain.  It is composed of side plates, where each plate straddles one end of a block and is connected to the block with a pin going through a hole at one end of the block.

Overview
Bar-link chains are simple, and often heavier and less efficient when compared with modern roller chains due to the lack of rolling motion as the chain engages and disengages the sprockets.

However, they have advantages in specific applications, especially where no sprockets are needed, where strength is a greater concern than efficiency (high loads), and where the chain has special fixtures for holding or engaging a load.

Reinforced-Concrete Highway Bridges in Minnesota MPS. Reinforced-Concrete Highway Bridges in Minnesota MPS is a Multiple Property Submission of bridges listed on the National Register of Historic Places in Minnesota.  The submission includes 20 individual bridges.  It also includes the Chicago, Milwaukee and St. Paul Railroad Grade Separation, which comprises 30 bridges built over the Milwaukee Road tracks one block north of Lake Street in Minneapolis.  The submission traces the historical context of reinforced concrete bridge building in Minnesota and cites examples of early and historic bridges.

The submission establishes criteria for bridges to be listed on the National Register.  The National Register contains four primary criteria:
 A. Properties significant to the broad patterns of American history.  This Multiple Property Submission selects bridges that are significantly relevant to a region's development and its transportation system.  The bridges in the Chicago, Milwaukee and St. Paul Railroad Grade Separation are listed in this category because while its bridges are not significant engineering achievements, they provided relief to citizens in south Minneapolis who had to deal with train traffic.
 B. Properties associated with a significant person in America's past.  However, bridges significant in conjunction with their architect are to be listed under criterion C.  It is possible, although unlikely, that a particular bridge may be associated with a significant person other than its designer, such as a politician or city official who advocated for its construction.
 C. Properties significant for their design and construction methods.  The Minnesota Historical Society, in preparing this MPS, decided to select bridges with important qualities.  For example, a bridge that is the oldest of its type, the last surviving member of its type, having the longest span of its type, or associated with a prominent major architect, will be selected as part of this MPS.
 D. Properties with information potential likely to yield information pertinent to history or prehistory.  This is not applicable to reinforced-concrete bridges in Minnesota.

The MPS also documents several eras that were important in reinforced-concrete bridge construction:
 Early experimental designs from the 1890s through 1911
 Early standardized designs promoted by the Minnesota Highway Commission from 1912 through 1921
 A period of Minnesota Highway Department, trunk highway, and major urban bridge building from 1921 through 1945

The Franklin Avenue Bridge and the Mendota Bridge are listed in the MPS as examples of monumental concrete arch bridge construction, but these bridges were listed on the National Register before the MPS was submitted.

Abraham Burton Cohen. Abraham Burton Cohen (March 9, 1882 – February 11, 1956) was an American civil engineer notable for his role in designing innovative and record-breaking concrete bridges such as the Delaware, Lackawanna and Western Railroad's Tunkhannock Viaduct, the world's largest concrete structure when completed. Cohen was an active member of the American Concrete Institute and earned ACI's Wason Medal for Most Meritorious Paper in 1927.

Biography
Cohen was Jewish, born in Chicago and died in East Orange, New Jersey. He earned a degree in civil engineering from Purdue University in 1905 and an honorary doctorate in 1949. Cohen spent a majority of his career with the Delaware, Lackawanna and Western Railroad (DL&W) before leaving in 1920 to form his own consulting practice in New York City. As a consulting engineer, he designed a number of concrete spans in Scranton, Pennsylvania, Binghamton, New York, and elsewhere. At least two of his works, the Tunkhannock Viaduct and Scranton's Harrison Avenue Bridge, are on the National Register of Historic Places. He died on February 11, 1956.

Kaiserliche Werft Kiel 463. 

Imperial German Navy seaplanes 463 to 466 were a unique seaplane design produced for the Navy's flying service during the First World War. The seaplane base at Kiel-Holtenau ordered the type as a training aircraft in 1915, and the Navy allocated a batch of four serial numbers to the design. No 463 and its siblings were conventional, two-bay biplanes with unstaggered wings of equal span and two open cockpits in tandem for the pilot and instructor. The undercarriage consisted of twin pontoons. The large, square rudder was hinged to the rear end of the fuselage, and extended below the ventral line of the fuselage. The inline engine was neatly cowled in, with the exhaust being collected together in a single stack that extended above the upper wing.

Kaiserliche Werft Kiel received an order for three machines in October 1915, and the first of these (No 463) was delivered to the seaplane testing unit (SVK – Seeflugzeug-Versuchskommando) at Warnemünde the following summer. It remained there under test for well over one year, and was not finally accepted for service until summer 1918. This lengthy delay was possibly due to the aircraft being used as a trainer at Warnemünde itself.

Two of the seaplane trainers (No 461–462) built at Kaiserliche Werft Wilhelmshaven were possibly built to substantially the same design, as was possibly one of the reconnaissance seaplanes (No 947) built there.

Kaiserliche Werft Wilhelmshaven 401. Imperian German Navy seaplanes numbers 401 to 403 were the only three examples of a unique seaplane design produced for the Navy's flying service during the First World War. Production of these types commenced in April 1915 in an effort to supply the navy with a seaplane trainer of contemporary design. With the outbreak of war, the output of Germany's major seaplane manufacturers was taken up with producing front-line types, and the only trainers available were obsolete or rebuilt machines withdrawn from their original duties. Number 401 and its two siblings were delivered to the Navy in August 1915.

Imperial German Navy seaplanes 461 and 462 were the only two examples of a seaplane design produced for the Navy's flying service during the First World War. Number 461 was built in October 1916 and Number 462 in September 1917 as the German seaplane bases searched for purpose-built training aircraft to supplement their collection of retired combat types.

This particular design, one of several developed by the Kaiserliche Werften, was a conventional, two-bay biplane with wings of unequal span. The pilot and instructor sat in tandem, open cockpits, and the undercarriage consisted of twin pontoons. It is possible that the design was related to one group of seaplane trainers built at Kaiserliche Werft Kiel (No 463–466) and also to that of an armed reconnaissance seaplane (No 947) later built at Wilhelmshaven. However, the rear fuselages and empennages of No 461 and 462 differed significantly from the machines built at Kiel.

Kaiserliche Werft Wilhelmshaven 945. 

Imperial German Navy seaplane Number 945 was the sole example of a unique seaplane design produced during the First World War. Throughout the war, the Kaiserliche Werft Wilhelmshaven had been producing small numbers of training seaplanes for the German Navy, but as the conflict continued, they built a small number of armed types as well, including Number 945. While the general layout of this aircraft was conventional enough for its day, it included a number of unusual features. The single-bay wings were braced with single, large I-struts, and the vertical stabiliser was virtually non-existent, consisting of little more than a stub on the dorsal side of the rear fuselage. The rudder was hinged to the end of the fuselage and hung down below it. The Navy classified it as a C3MG type; indicating armament with both fixed and trainable machine guns.

Number 945 was ordered in 1917, and a photograph of the completed aircraft exists, bearing its military markings and serial number. However, there is no record of this aircraft ever being delivered to the Navy.

The Kaiserliche Werft Wilhelmshaven 947 was a maritime reconnaissance floatplane built for the Imperial German Navy's () Naval Air Service () during the First World War, the sole example of its type. It was one of only three armed aircraft built by the Kaiserliche Werft Wilhelmshaven amongst a variety of trainer seaplanes that they had produced for the Navy during the course of the war. Number 947 was a two-bay biplane of conventional design, with twin pontoon undercarriage, and two open cockpits in tandem. It received the Naval classification CHFT, indicating an armed aircraft equipped with radio gear capable of both sending and receiving.

The design bore a resemblance to a pair of trainer seaplanes produced at Wilhelmshaven (Nos 461–462) and to a design from Kaiserliche Werft Kiel (Nos 463–466), and all three designs could have been the work of the same designer or designers. The machine was evaluated by the seaplane testing unit (SVK – Seeflugzeug-Versuchskommando) at Warnemünde at some point, but the records that have survived are somewhat contradictory. In any case, no further examples were constructed.
