Mather Lane Mill. Mather Lane Mills was a complex of cotton mills built by the Bridgewater Canal in Bedford, Leigh in Lancashire, England. The No 2 mill and its former warehouse are grade II listed buildings.

History
The Mather Lane Company was formed at a meeting in the Black Horse public house in Leigh. Thomas Smith, a self-educated man was voted to the chair and Richard Thomas Marsh became its managing director from its inception until 1920. The first mill's working capital was £60,000 when it became operational in 1878. A second mill opened in 1883 and the third in 1891. In the 1920s, the company was merged into Combined Egyptian Mills Ltd.

Architecture

The second Mather Lane Mill is a Grade II listed cotton spinning mill on the north bank of the Bridgewater Canal. It was built in 1882 to the designs of Bradshaw and Gass of Bolton and is notable for its severe classical elevations. It is an important early factory design by the architects and has features unusual for its date including a square plan, flat roof and its partly internal engine house. The mill has six storeys and a basement built in brick in English garden wall bond with panelled pilasters at the corners. Three-storey carding sheds on the south side are parallel to the canal and set obliquely to main mill. Its engine house is on the north side and its tower at the north-west corner is panelled with moulded string courses. The tower rises above parapet level where there are large lunettes below a blind arcade of round-headed arches, parapet and it has a pyramidal roof.

The mill's six by ten bays contain iron-framed windows. The east and west elevations have large windows with continuous central iron box columns rising through the first to fourth floors. The north and south elevations have single-light windows. Inside the ceilings are supported by iron girders on Tuscan columns.

Mill No 2, was redeveloped in the early 2020s by JP McGuire Developments in 98 one, two and three bedroom apartments called Loom Wharf. It forms a modern residential complex, utilising the former cotton stores in the basement as car parking, seven levels of luxury apartments and state of the art gym facilities.

Mill No 3, also known as Brooklands Mill, was constructed on the opposite (south) side of the Bridgewater Canal.

Warehouse

The mill's former warehouse on the opposite side of Mather Lane is also grade II listed.  It was built around 1882, probably also to designs by Bradshaw and Gass. It is a plain brick structure with three storeys overlooking the canal. It has hoists and taking-in bays on the front and canal elevations.

Bloch MB.141. The Bloch MB.141 was a French all-metal two seat light aircraft derived from the Bloch MB.81 air ambulance. Only one was built.

Design and development

The MB.141 was a low wing cantilever monoplane with a three part wing consisting of a rectangular plan centre section and trapezoidal outer panels. It was built around two spars and metal skinned; the leading edges were removable for maintenance purposes and the trailing edges carried high aspect ratio ailerons which filled about two-thirds of the outer panels.

Its  five cylinder Hispano-Suiza 5Q radial engine (a licence-built Wright R-540) was mounted in the nose within a narrow-chord cowling. Behind it the fuselage was flat-sided, constructed from panels linked by frames which left the interior free of cross-bracing. The well-appointed cabin was  long with two seats in tandem, fitted with dual controls, and a luggage space behind. The forward seat was behind a two piece, V-shaped windscreen and on each side there was a pair of windows; on the port side the largest of these was in the large, trapezoidal door.

Behind the cabin the fuselage tapered to a conventional tail with straight-tapered, square-tipped surfaces.  The tailplane and elevator were mounted near the top of the fuselage and well ahead of the rudder hinge. The control surfaces were not balanced.

The MB.141 had a fixed tail wheel undercarriage with a track of ; its main wheels were mounted on vertical, faired oleo struts and had brakes operated by a lever on the control column. Its small, castoring tail wheel also had a shock absorber.

Its first flights were made towards the end of July 1934, piloted by Bloch's test pilot Zacharie Heu, who spoke highly of its handling. It has been described as "too heavy", possibly underpowered as it weighed a little more than the MB.81 but had a less powerful engine. It was also expensive to construct, so only one MB.141 was built.

It is unusual for an unflown prototype aircraft to be the first prize in a lottery but in April 1934 the MB.141 was donated by Marcel Bloch to the Ecole Nationale Supérieure de l'Aéronautique. The lottery was advertised in the French aviation press and drawn on 22 July 1934; the winning ticket was announced at the end of August.

Richard Johnson (engineer). Richard Johnson, MICE (1827 – 9 September 1924) was a British railway engineer, latterly chief engineer for the Great Northern Railway (GNR).

Life and career
Johnson was born in Spalding, Lincolnshire, and began his career as an apprentice carpenter in 1840. He joined the engineering firm Brydone and Evans in 1847, working on the GNR. He was promoted in 1855 to become the district engineer for the GNR's loop line and then again in 1859 to take responsibility for the Peterborough to Doncaster route. In 1861 he became chief engineer to the GNR upon the retirement of his predecessor Walter Marr Brydone. He was in-post at the time of the Welwyn Tunnel rail crash (1866). He went on to oversee the construction of the GNR Derbyshire and Staffordshire Extension, which involved several significant bridges, including Giltbrook Viaduct in Nottinghamshire, Bennerley Viaduct near Ilkeston on the Nottinghamshire–Derbyshire border, and two in Derby: the Handyside Bridge over the River Derwent and the Friargate Bridge carrying the approach tracks to Derby Friargate railway station, as well as the Kimberley Cutting. Johnson was also involved in the construction of bridges at Newark (at , the longest on the GNR, reconstructed in 1889–90, in place of the 1851-52 Warren Truss bridge), Doncaster (the Don Bridge), Peterborough, and the Copenhagen Tunnels just north of London King's Cross. He retired in 1896. In his 35 years as CE he converted the whole of the GNR from iron to steel rails.

In his personal life, Johnson was teetotal, avoiding all forms of alcohol, and a Christian missionary. He died on 9 September 1924 in Hitchin. His son, T R Johnson, was GNR Assistant Engineer and, from 1907 to 1914, New South Wales Chief Railway Commissioner.

2,2-Dimethylpentane. 2,2-Dimethylpentane is one of the isomers of heptane. It is also called neoheptane as it contains the (CH3)3C grouping. It has the most extreme properties of the isomers of heptane.

Preparation
A method to produce high purity  2,2-dimethylpentane is to react the grignard reagent of n-propyl bromide (CH3CH2CH2MgBr) with tert-butyl chloride ((CH3)3CCl). n-PrMgCl can be used instead of the bromide.

Properties
In 1929 Graham Edgar and George Calingaert made 2,2-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times.

For 2,2-dimethylpentane they measured a density of 0.6737 at 20 °C with a rate of change Δd/ΔT of 0.000855. The density and boiling are the lowest of the isomers of heptane. The dielectric constant is 1.915, the lowest of the heptane isomers. The critical temperature is 247.7 °C and critical pressure 28.4 atmospheres. The refractive index at 20° is 1.38233, the same as for 2,4-dimethylpentane, equal lowest for the heptane isomers. The adiabatic compressibility is 0.0001289 and isothermal compressibility is 0.00016279 atmospheres, highest for the heptanes. The velocity of sound is 1.080 km/s which is lowest of the heptanes. Coefficient of thermal expansion is 0.001268/°, highest of the heptanes. Surface tension is 17.80 dynes/cm. Viscosity is 0.00385. The heat of combustion is 11470 cal/g which is very similar to other heptanes.

Reactions
2,2-Dimethylpentane can form a clathrate hydrate with helper gas molecules. The type of clathrate formed is called "clathrate H". 2,2-Dimethylpentane was the first compound for which the structure was determined. The clathrate has 34 molecules of water per molecule, and also has xenon and hydrogen sulfide as helper molecules. The crystals are hexagonal in form and melt at 0.6 °C. This substance is important as clathrate hydrates form problems by blocking natural gas pipelines.

2,2-Dimethylpentane does not react with bromine, iodine, nitric acid or  chlorosulfonic acid because there are no tertiary carbon atoms (a carbon atom with only one hydrogen attached).

Heating alkanes over an aluminium trichloride is used to reform to make different isomers. 2,2-Dimethylpentane does not participate in this process and so cannot be reformed, or created by reforming other heptanes.

Natural occurrence
2,2-Dimethylpentane exists in some crude oils at low levels of about 0.01%.

2,4-Dimethylpentane. 2,4-Dimethylpentane is an  alkane with the chemical formula [(H3C)2CH]2CH2. This colorless hydrocarbon is produced in large quantities in oil refineries.  It results from the alkylation of isobutane by propylene.  Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.  Unlike n-heptane, 2,4-dimethylpentane is a desirable fuel because its branched structure allows combustion without knocking.

3,3-Dimethylpentane. 3,3-Dimethylpentane is one of the isomers of heptane. 3,3-Dimethylpentane has a boiling point of 86.0 °C and melting point of −134.9 °C. Its density is 0.6934. The refractive index is 1.39092 at 20 °C.

Preparation
A method to produce 3,3-dimethylpentane is to react tert-amyl chloride (CH3CH2(CH3)C2Cl) with propionaldehyde producing 3,3-dimethylpentan-2-ol. This is then dehydrated to produce 3,3-dimethylpent-2-ene, which when hydrogenated produces some 3,3-dimethylpentane, but also 2,3-dimethylpentane.

Properties
In 1929 Graham Edgar and George Calingaert made 3,3-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times.

For 3,3-dimethylpentane they measured a density of 0.6934 at 20 °C with a rate of change Δd/ΔT of 0.000848. The dielectric constant is 1.940. The refractive index at 20° is 1.39114. The adiabatic compressibility is 0.00011455 and isothermal compressibility is 0.00014513 atmospheres. The velocity of sound is 1.1295 km/s. Coefficient of thermal expansion is 0.002467/°. Surface tension is 19.63 dynes/cm. Viscosity is 0.00454. The heat of combustion is 11470 cal/g which is very similar to other heptanes.

Eddy-current sensor. Eddy current sensors are displacement sensors that use the principle of eddy current formation to sense displacement. These sensors measure shaft displacement in rotating machinery and have been around for many years as they offer manufacturers high-linearity, high-speed measurements, and high resolution. Eddy currents are formed when a moving or changing magnetic field intersects a conductor or vice versa. 

The relative motion causes a circulating flow of electrons, or currents, within the conductor. These circulating eddies of current create electromagnets with magnet fields that oppose the effect of applied magnetic field. The stronger the applied magnetic field, or greater the electrical conductivity of the conductor, or greater the relative velocity of motion, the greater the currents developed and greater the opposing field. Eddy current probes senses this formation of secondary fields to find out the distance between the probe and target material.

Boonal Joint Venture. The Boonal Joint Venture is a coal load out facility located on the Capricorn Highway in Central Queensland of Australia.  Coal from Both Yarrabee coal mine and Jellinbah coal mine are railed to the Port Of Gladstone from the Boonal load out facility.  Coal is delivered by road train to the Boonal coal pad and is then stockpiled by track dozers.  Track dozers then push the stockpiled coal into a reclaim hopper that feeds a surge bin on the opposite side of the highway.  An operator then loads the individual train wagons with the surge bin from a control room.
