Aalborg Portland. Aalborg Portland is a cement-producing company in Denmark. It was established in Aalborg in the 19th century. Portland cement was patented in 1824 by the Englishman Joseph Aspdin. Six decades later the Aalborg businessman Hans Holm and the engineer Frederick Læssøe Smidth built a cement factory  northeast of Aalborg in the town of Rørdal.

The Aalborg Portland-Cement Factory was founded in 1889. Aalborg Portland produces four major products: grey cement, white cement, ready-mixed concrete and aggregates. In 1898, the company's growth accelerated after it purchased two rotary kilns from the Philadelphia-based company Laxhbury & Spackman. In 2009 the Sinai White Portland Cement division became the "biggest white cement integrated plant worldwide in terms of capacity". Since 2003, the company is a subsidiary of Cementir Holding S.p.A. The sale was approved by competition authorities in 2004. In 2013 it had a workforce of over 1,500.

In 2019, Aalborg Portland had 335 employees in Denmark.

Impact on climate change 
Aalborg Portland is considered the biggest polluter in Denmark. The emissions of the industrial company in 2018 were equivalent to 2.2 million tons of CO2, or 4% of the national CO2 emissions.

According to the Danish Economic Council, the cement industry does not have a sufficient economic interest to reduce its CO2 emissions, because the price to pollute is too low. In 2022, Aalborg Portland announced a corporate roadmap that sets an emissions ceiling target of no more than 600,000 tons by 2030.

Molybdenum(III) chloride. Molybdenum(III) chloride is the inorganic compound with the formula MoCl3. It forms purple crystals.

Synthesis and structure
Molybdenum(III) chloride is synthesized by the reduction of molybdenum(V) chloride with hydrogen. A higher yield is produced by the reduction of pure molybdenum(V) chloride with anhydrous tin(II) chloride as the reducing agent.

Molybdenum trichloride exists as two polymorphs: alpha (α) and beta (β). The alpha structure is similar to that of aluminum chloride (AlCl3). In this structure, molybdenum has octahedral coordination geometry and exhibits cubic close-packing in its crystalline structure. The beta structure, however, exhibits hexagonal close packing.

Ether complexes
Molybdenum trichloride gives a ether complexes MoCl3(thf)3 and MoCl3(Et2O)3. They are beige, paramagnetic solids.  Both feature octahedral Mo centers.  The diethyl ether complex is synthesized by reducing a Et2O solution of MoCl5 with tin powder.  Older procedures involve stepwise reduction involving isolation of the Mo(IV)-thf complex.

Hexa(tert-butoxy)dimolybdenum(III) is prepared by the salt metathesis reaction from MoCl3(thf)3:
2 MoCl3(thf)3  +  6 LiOBu-t  →  Mo2(OBu-t)6  +  6 LiCl  +  6 thf

Molybdenum(III) bromide. Molybdenum(III) bromide is the inorganic compound with the formula MoBr3. It is a black solid that is insoluble in most solvents but dissolves in donor solvents such as pyridine.

Preparation
Molybdenum(III) bromide is produced by the reaction of elemental molybdenum and bromine at .

It can also be prepared from the reduction of molybdenum(IV) bromide with molybdenum metal, hydrogen gas, or a hydrocarbon.

It has a structure consisting of infinite chains of face-sharing octahedra with alternatingly short and long Mo-Mo contacts. The same structure is adopted by the tribromides of ruthenium and technetium.  In contrast, in the high temperature phase of titanium(III) iodide, the Ti---Ti separation is invariant.

Molybdenum(III) iodide. Molybdenum(III) iodide is the inorganic compound with the formula MoI3.

Preparation
Molybdenum(III) iodide is created by the reaction of molybdenum hexacarbonyl with iodine gas at .

2 Mo(CO)6 + 3 I2 → 2 MoI3 + 12 CO

It can also be made from molybdenum(V) chloride and a solution of hydrogen iodide in carbon disulfide.

MoCl5 + 5 HI → MoI3 + 5 HCl + I2

A further method is direct reaction between molybdenum metal and excess iodine at .

2 Mo + 3 I2 → 2 MoI3

As molybdenum(III) iodide is the highest stable iodide of molybdenum, this is the preferred route.

Properties 
Molybdenum(III) iodide is a black antiferromagnetic solid that is air-stable at room temperature. In vacuum, it decomposes above 100 °C to molybdenum(II) iodide and iodine. It is insoluble in polar and non-polar solvents. Its crystal structure is isotypic with zirconium(III) iodide.

Sand equivalent test. The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933–8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is less clay‐like material in a sample.

During the test, material from the test specimen that can pass through a No. 4 sieve is mixed with solutions of calcium chloride, formaldehyde and glycerin in a cylinder. The content is then left for sedimentation. After about 20 minutes, the level of clay suspension and the sand level is read on the cylinder scale.

Skyjam ST-Freestyle. The Skyjam ST-Freestyle is a Swiss electric aircraft that can be flown as an ultralight trike, powered parachute and powered paraglider. It was designed and produced by Skyjam Paragliders of Einsiedeln, but the company appears to be out of business as of 2013 and production is assumed to be complete. When it was available the aircraft was supplied as a complete ready-to-fly-aircraft.

Design and development
The aircraft is made from bolted-together aluminum tubing. In its ultralight trike configuration the ST-Freestyle features a cable-braced hang glider-style high-wing covered in Dacron sailcloth, supported by a single tube-type kingpost with weight-shift controls utilizing an "A" frame weight-shift control bar. The trike wing can be removed and a powered parachute wing substituted in a few minutes. In that configuration the wing is controlled by conventional paraglider brakes for steering. The engine package can also be removed from the wheeled fuselage frame and the aircraft then foot-launched as a powered paraglider using the same wing.

Pilot accommodation is a single-seat open cockpit without a cockpit fairing. The ST-Freestyle has tricycle landing gear and a single electric motor in pusher configuration. The powerplant is a ST Elektro ST100 or ST200 electric motor driving a shrouded three-bladed composite propeller.

Kregel Windmill Museum. The Kregel Wind Mill Company produced water pumping windmills in Nebraska City, Nebraska starting in 1879.  It is now the Kregel Windmill Factory Museum.

History
The brand of windmills that the Kregel Windmill Company produced was called "ELI" — as an homage to one of George Kregel's friends, a deceased preacher named Eli Huber. Kregel windmills were used to pump water from wells at farms and homes in the region of southeastern Nebraska surrounding Nebraska City. Managed by George F. Kregel, the company moved to the current Central Avenue building in 1903, continuing to operate there for 88 years.

The Central Avenue factory has been preserved with all of its manufacturing equipment. The machinery in the factory is powered by a central transverse line shaft and leather belts coming down to pulleys on each machine. The line shaft itself was originally powered by a single cylinder engine, but was converted to electricity in the 1920s. After manufacturing more than 2000 windmills, the company stopped production in the 1940s, and the Kregels worked instead in pump repair and well maintenance until 1991 in the same location.

The factory is a one-story wood-frame building. The flat-roofed building has two small roof monitors for light and ventilation. The front facade is clad with pressed sheet metal in a brick pattern, with four bays. The interior is a large open space with two structural bays, and a small office space. All of the company's tools (including "ledger books on shelves, telephone, pencils and pens on the desk, even an overcoat on a hook") and records have been preserved.

Since September 2019, the executive director has been Isaiah Yott.

Solid Fuels Administration for War. The Solid Fuels Administration for War (SFAW) was a U.S. federal agency that administered wartime government controls on solid fuels industries.

According to Executive Order 9332 Establishing the Solid Fuels Administration for War,
The term "solid fuels" includes all forms of anthracite, bituminous, sub-bituminous, and lignitic coals (including packaged and processed fuels, such as briquettes) ...

The term "solid fuels industries" means the development, production, preparation, treatment, processing, storage, shipment, receipt, and distribution of solid fuels within the United States, its territories and possessions, but does not include the transportation of solid fuels.

It also advised other agencies, such as the Office of Defense Transportation, the War Shipping Administration, and the War Manpower Commission concerning solid fuels production, pricing, transportation, and distribution. 

It operated government-seized coal mines, either directly or through cooperation with successive Coal Mines Administrations.

It was established within the Department of the Interior by EO 9332, April 19, 1943, replacing the Office of Solid Fuels Coordinator for War; and absorbing functions of the abolished Bituminous Coal Division, Department of the Interior, August 24, 1943.

It was abolished, effective June 30, 1947, by EO 9847, May 6, 1947.

Signal boxes that are listed buildings in England. 
A number of signal boxes in England are on the Statutory List of Buildings of Special Architectural or Historic Interest. Signal boxes house the signalman and equipment that control the railway points and signals. Originally, railway signals were controlled from a hut on a platform at junctions. In the 1850s, a raised building with a glazed upper storey containing levers controlling points and signals was developed after John Saxby obtained a patent in 1856 for a mechanical system of interlocking the points and signals. Over half of the signalboxes before 1923 were built by private signalling contractors, the largest being Saxby & Farmer; Stevens & Sons, McKenzie & Holland, the Railway Signal Co., Dutton & Co and Evans, and O'Donnell & Co. Some railway companies had a standard signalbox design, such as the London & North Western Railway, whereas others, such as the Great Eastern Railway had many different designs.

Listed buildings are given one of three grades: Grade I for buildings of exceptional interest, Grade II* for particularly important buildings of more than special interest and Grade II for buildings that are of special interest. In 1948 there were approximately 10,000 signal boxes; by 2012 this had reduced to about 500. National Rail has plans to concentrate control at twelve centres by 2040, decommissioning most of the remaining mechanical signal boxes by 2025. A joint Historic England and Network Rail project listed 26 signal boxes in July 2013.

Signal boxes and swing bridge cabins are listed Grade II, except for those noted as Grade II*.
