Heat cost allocator. Heat cost allocators are devices attached to individual radiators in buildings that measure the total heat output of the individual radiator. Heat cost allocators can be either electronic, where one or two electronic thermosensors and a microcontroller are used to calculate the heat consumption of radiator by the temperature difference between the radiator and the air in room, or evaporative, where a special, calibrated liquid in a capillary tube records the total heat absorbed from the air (for which an average allowance is made) in addition to that output by the radiator.

Tubes filled with methyl benzoate according to DIN EN 835 can be used by checking the color change.

Working principle:

As the radiator heats up, the back section also heats up. The temperature (or the temperature difference to room temperature for electronic two-sensor devices) is integrated over the heating period (one year according to the heating costs ordinance) and thus forms the measured value. Since the amount of heat emitted also depends on the size and type of radiator and the heat transfer between the radiator and the heat cost allocator, the measured value of each radiator is multiplied by an individual factor. This can be done in the heating bill. One then speaks of a unit scale, because every heat cost allocator is equipped with the same scale. If, on the other hand, the heat cost allocators on different radiators are equipped with different scales, so-called product scales, no conversion takes place because the factor has already been taken into account by the choice of scale. With electronic heat cost allocators, the scaling is achieved through programming. The evaluation factor is determined when the heat cost allocator is installed. For this purpose, the manufacturer and type of the radiator - as far as possible - are determined and measurements are taken. This leads to the radiator performance as the first part of the evaluation factor. The factor is then corrected by the so-called Kc value, which describes the heat transfer between the heating medium, ultimately the radiator, and the heat cost allocator. The radiator evaluation requires the knowledge of precise data about the heat cost allocator used and the radiator, which are obtained in extensive series of measurements and tests.

Bell Boy (boat). The Bell Boy Boat Company was a division of the Bellingham Shipyards Co. of Bellingham, Washington set up by the shipyard owner Arch Talbot in 1952. Talbot was interested in creating a line of fiberglass boats, having worked with the material when the shipyard created of line of lifeboats for minesweepers in the Korean War called wherries. The company's use of fiberglass was pioneering; the material, despite having its commercial introduction in the 1930s, had seen limited use or interest until the postwar period. The Bell Boy line of boats, during the 1950s and 1960s, were considered to be one of the earliest types of fiberglass boats.

SECR J class. The SECR J class was a class of 0-6-4T  steam tank locomotive built for heavy freight service on the South Eastern and Chatham Railway, by Harry Wainwright.

History
The South Eastern and Chatham Railway (SECR) had a need for versatile mixed traffic locomotives which could accelerate quickly so as not to impede the heavy passenger traffic on the densely used lines around London. Following the success of his  C class 0-6-0 and his H class 0-4-4T Harry Wainwright sought to combine their good features but was limited by weight restrictions on many lines. The result was an 0-6-4 tank. Five locomotives were constructed at Ashford during 1913, but Wainwright retired soon afterwards and no more were constructed. The class were moderately successful on a variety of secondary passenger and freight services. All had completed more than one million miles at the time of their withdrawal between 1949 and 1951.

Numbering
The class were originally allocated unused numbers between 126 and 614. However, all but number 597 were renumbered by the  Southern Railway in 1927/8 to create a unified sequence from A596 to A599. These later became 1596–1599, and then 31596–31599 under British Railways.

The Earth Suspended River. The Earth Suspended River (地上悬河 is located in the lower reaches of the Yellow River, which is a world-famous geographical landscape. Also known as 'the raised bed river', its bed is more than 3 metres higher than the ground. In some places, the water level is even about 10 metres higher than the ground.

The Yellow River is known for being sandy with very high sediment concentration. The reasons are the ascent of this reach is not big, both sides of the river are open, and the current is gentle too. Above all, the sand deposits constantly in the bed. In history, the region was hit by floods frequently, so people built levees for the purpose of governing the floods. As a result, the water level increased continuously year by year. After accumulation of over 300 years, the reach becomes what it is now.

José Zanier. José Zanier (Udine, Italy, September 18, 1905 – Mar del Plata, Argentina January 30, 1973) was an Italian engineer and pioneer in the construction of thermo-electric power stations supplied by diesel motors. He also worked on projects involving the Italian interconnecting 230 and 150 kV electricity lines, as well as making other contributions to the development of the electro-technical field.

Biography 
In 1932 he planned and supervised the construction of the post office and telecommunications building in Vicenza, Italy. Soon thereafter, he focused his attention on the building of the scholastic Noventa Vicentina monument in Vicenza.

In 1936, as director of the technical office of UMET in Rome, part of the Superior Council for Public Works, he developed plans for the Italian 230 and 150 kV interconnection lines with 400 MW of transferable electric power, with their respective transformation and regulation substations.

Just before the outbreak of World War II, he installed the first 20,000 kVA steam-turbo generators, with automatic boilers, in Rome's thermal power station - the first of their kind.

As chief engineer for energy distribution at AGEA, the Italian state electricity and water company, in 1933 he planned the construction and usage of high- and low-tension electricity lines in central and southern Italy, designed to supply electricity to the so-called "Agro Romano".

Immediately after the war he was hired by the Argentine government to construct the modern thermal "Dean Funes" power station in Córdoba, Argentina, which had two 2,500 kW steam-turbo generators.

In 1950, as chief engineer, he planned and built the "9 July" thermal power station in Mar del Plata, the only one of its kind with a power capacity of 20,000 kW. A pipeline connecting to the YPF and subterranean water refrigeration tunnels connected to the sea complete the generator which continues to supply this seaside town today.

Graz VL-1 Maulwurf I. 

The construction of the "Maulwurf I" was carried out under adverse conditions and the lack of resources. It was only completed once Major General Ing Pedretti generously provided some rooms for final assembly in the artillery laboratory.

The first preliminary test flights were completed on 18 February 1923 at the military firing range Feliferhof. Under the expert guidance of Major Erich Kahler, the former commander of the airfield Thalerhof, the apparatus was prepared for first flight.

River Works. River Works, formerly known as Air Force Plant 29, is a plant of General Electric's aviation division located in Lynn, Massachusetts. It is serviced by the River Works station on the MBTA's Newburyport/Rockport Line. It was purchased by General Electric in 1983 from the United States Air Force.

History
The Thomson-Houston Electric Company moved its operations to a new factory building on Western Avenue in West Lynn in 1883. By 1892, it had expanded into a sprawling factory complex between Western Avenue and the Boston and Maine Railroad Eastern Route tracks. That year, the company merged with Edison General Electric to become General Electric (GE). By 1894, the Lynn plant was known as the "river works" after its position along the Saugus River.

The factory was expanded in 1943 as a supercharger facility (Air Force Plant No. 29), and helped to build the first jet engine during World War II. Activities performed at the plant originally included aircraft engine testing, disassembly, lubricating, cleaning and assembly. Operations included, degreasing, electrochemical grinding, engine maintenance, metal washing, parts cleaning and stress fracture testing. 

The workers at the facility were known for leftist politics, joining the new United Electric Workers union in 1936. They were targeted by state and federal governments during the Second Red Scare; in 1954, Joseph McCarthy subpoenaed five employees. 

From 1968 to 1972, the 'Pilot Program' was introduced. Faced with rising tensions on the shop floor, bottle-necks in production and low-quality products, GE management tried a scheme of workers' control of production in one area of the plant. Immediate results in increased output and machine utilisation, and a reduction on manufacturing losses but was eventually terminated by the management. The plant had operations boosted in the late 1980s after General Electric decided to close the General Electric Everett Plant and move operations there.

Georgia Railroad Freight Depot. The Georgia Railroad Freight Depot (1869) is the oldest building in downtown Atlanta.

It is located on the east side of Central Avenue, bordered by the MARTA and freight railroad lines on its north side. It anchors the north side of Steve Polk Plaza, which contains the old World of Coca-Cola building at its south side and an entrance to Underground Atlanta, via a tunnel under Central Avenue, on its west side.

The depot was completed in 1869. The architects were (Max) Corput and Bass. It was the main freight depot for the Georgia Railroad and Banking Company.

A fire in 1935 destroyed the upper floors and the cupola.

In 1981 the building was renovated to accommodate events. It can accommodate 800 seated guests or 1300 standing.

American Aerolights Eagle. The American Aerolights Eagle is an American ultralight aircraft that was produced by American Aerolights, introduced in 1975. The aircraft was supplied as a kit for amateur construction.

Different sources attribute the design to Larry Hair or Larry Newman.

Design and development
The Eagle was designed before the US FAR 103 Ultralight Vehicles rules were introduced, but it fits into the category, including the category's maximum empty weight of . The Eagle 215B has a standard empty weight of . It features a cable-braced high-wing, canard, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum alloy tubing, with the flying surfaces covered in 4 oz Dacron sailcloth. Its  span wing cable bracing from a single kingpost. The wing incorporates downwards pointing wing tip rudders and a trailing edge that was defined only by the sailcloth edge. This latter feature caused a number of fatal accidents due to sailcloth UV deterioration. Heavier weight sailcloth was substituted and finally a steel cable was used at the trailing edge. A fore and aft boom that acts as the wing keel also supports the canard surface. Different Eagle models used different control systems, gradually becoming more conventional over time. Assembly time from the kit is 75 hours.

The Eagle was built in several models and in very large numbers. A two-seat version, the Double Eagle was produced and used by the  Monterey Park, California Police Department in 1981. The accidents from the trailing edge design resulted in a number of lawsuits that eventually drove the company out of business.

Variants
Eagle 215B
First model, introduced in 1975. It has an unconventional control system, with pitch controlled by the canard surface, which is actuated by pilot weight shift fore and aft in the sling seat. A side stick deflects the wing tip rudders to create drag which causes yaw; the wing's dihedral effect then produces roll. Empty weight , gross weight 
Eagle XL
Later model with a more conventional control system. A stick controls the canard surface for pitch control and wing-mounted spoilers for roll control. The downwards-pointing wing tip rudders are retained and enlarged, but controlled by rudder pedals.
Double Eagle
Two seat model.

Joint Center for Artificial Photosynthesis. The Joint Center for Artificial Photosynthesis (JCAP), founded in 2010, is a (DOE) Energy Innovation Hub whose primary mission is to find a cost-effective method to produce fuels using only sunlight, water, and carbon-dioxide. The program has a budget of $122M over five years, subject to Congressional appropriation.

The Director of JCAP is Professor Harry Atwater of Caltech and its two main centers are located at the California Institute of Technology and the Lawrence Berkeley National Laboratory. In addition, JCAP has partners from Stanford University, the University of California at Berkeley, University of California at Santa Barbara, University of California at Irvine, the University of California at San Diego, and Stanford Linear Accelerator. In addition, JCAP also serves as a hub for other solar fuels research teams across the United States, including 20 DOE Energy Frontier Research Center.

In Obama's 2011 State of the Union address, he mentioned the Joint Center for Artificial Photosynthesis. Specifically, he said, "We're issuing a challenge. We're telling America's scientists and engineers that if they assemble teams of the best minds in their fields, and focus on the hardest problems in clean energy, we'll fund the Apollo projects of our time. At the California Institute of Technology, they're developing a way to turn sunlight and water into fuel for our cars".
