Merlin-class sloop. The Merlin class was a class of twenty-one sloops of wooden construction built for the Royal Navy between 1743 and 1746. They were all built by contract with commercial builders to a common design prepared by Jacob Acworth, the Surveyor of the Navy; however, there were small differences between individual vessels, with a platform deck being constructed in the hold in Swallow (i), Merlin, Raven and Swallow (ii), whereas the other seventeen had no platform deck and thus their depth in hold was thus nearly twice as much.

The Merlin class design was one of two standard designs to which all Royal Navy sloops were built between 1743 and 1748 (the other design being the Hind class designed by Acworth's colleague Joseph Allin), who was appointed to share the post of Surveyor with Acworth on 11 July 1745.

Although initially each was armed with ten 6-pounder guns, this class was built with seven pairs of gunports on the upper deck, enabling them to be re-armed with fourteen 6-pounders later in their careers.

The first two – Swallow and Merlin – were ordered on 7 July 1743 to be built to replace two ex-Spanish vessels (the Galgo and Peregrine's Prize, both captured in 1742, and put into service by the British). Two more vessels to the same design were ordered on 30 March 1744; another two were ordered five days later, four more followed on 23 May and three others were ordered later that year.

On 5 April 1745 five more were ordered – including a second Falcon (named to replace the first, captured in the same year) and a second Swallow (similarly to replace the first, wrecked in 1744) – and a single extra vessel was ordered on 11 April. A final pair were ordered on 9 January 1746.

Oil mist lubrication. Oil mist lubrication is a method of lubricating machinery and equipment that involves delivering a fine mist or aerosol of oil particles into the lubrication points where friction and wear occur. Oils are applied to rolling element (antifriction) bearings as an oil mist. Neither oil rings nor constant level lubricators are used in pumps and drivers connected to plant-wide oil mist systems. Oil mist is an atomized amount of oil carried or suspended in a volume of pressurized dry air. The oil mist, actually a ratio of one volume of oil suspended or carried in 200,000 volumes of clean, dry air, moves in a piping system (header). The point of origin is usually a mixing valve (the oil mist generator), connected to this header. Branch lines often feed oil mist to hundreds of rolling elements in the many pumps and drivers connected to a plant-wide system.  

At standstill, or while on standby, pump and driver bearings are preserved by the surrounding oil mist, which exists in the bearing housing space at a pressure just barely higher than ambient. These pump and driver bearings are lubricated from the time when atomized oil globules join (or wet out) to become larger oil droplets. This joining-into-large-droplets starts whenever the equipment shafts rotate, which is when small globules come into contact with each other and start coating the bearing elements. 

As of April 2019, over 160,000 process centrifugal pumps are operating with oil mist as the sole bearing lubricant. The estimated number of electric motors on pure oil mist exceeds 50,000; several of these at a Texas Gulf Coast petrochemical facility have been in flawless service since 1978. Oil mist technology is mature and has been in highly successful plant-wide use since the early 1960s.

There are also plant-wide oil distribution systems whereby liquid oil (not an oil/air mixture) is pressurized and injected, through spray nozzles, into the pump bearings. These oil spray systems are not to be confused with the more economical oil mist systems. However, both oil mist and oil spray applications can take credit for lower frictional losses and both should be taken into account while performing cost justification analyses. These analyses are highlighted in Bloch/Geitner/Ehlert "Optimized Equipment Lubrication, Oil Mist Technology, and Storage Preservation," (late 2019), Reliabilityweb Publishing, Ft. Myers, Florida.

MakerPlane. MakerPlane is an open source aviation organization, started by a group of Canadian plane building enthusiasts. Its members are designing the first open source airplane, which they estimate could cost about US$15,000 to build.

Many do-it-yourself aircraft projects are abandoned before they are completed.  Some of the causes are complex and vague plans and assembly instructions, lack of builder support, the thousands of hours needed to create a complete plane and manufacturers of parts and plans going out of business.  The MakerPlane members participate in networking, share information and work together on a simple and economical plane design, and make some of their own parts, in order to overcome these obstacles.

Aircraft designs 
In 2011 the MakerPlane community began designing their aircraft from the ground up to be built using modern and affordable personal manufacturing equipment, such as CNC mills and 3D Printers.  The first design is a 2-seat Light Sport Aircraft, currently under the working name of "MakerPlane v1.0 LSA".  The designs are to be released under a Creative Commons license. The first prototype was expected to be flown in 2015 and shown at the AirVenture OshKosh shows in 2014 and 2015

Events
In 2013, MakerPlane initiated a Kickstarter campaign and an Indiegogo campaign to fund development of its plane.  During the first few months, these campaigns did not succeed in raising a significant amount of money.

In January, 2014, MakerPlane successfully flew its first scale model.

In June 2019, after 5 years with no news, the project exhibited at AirVenture.

4751st Air Defense Squadron. The 4751st Air Defense Missile Squadron is a discontinued United States Air Force unit.  It was last active with Air Defense, Tactical Air Command (ADTAC), based at Eglin Air Force Base, Florida.  It was inactivated on 30 September 1979.

History
In September 1958 Air Research and Development Command decided to transfer the Bomarc long range surface-to-air missile program from its testing site at Cape Canaveral Air Force Station to a new facility on Santa Rosa Island, immediately south of Eglin AFB on the Gulf of Mexico.  At Eglin, an Operational Testing facility and Operational Training Unit would be created under the jurisdiction of Air Defense Command, under which operational Bomarc units would be established and supported.

To operate the facility and to provide training and operational evaluation in the missile program, ADC established the 4751st Air Defense Wing (Missile) (4751st ADW) on 15 January 1958. The first launch from Santa Rosa took place on 15 January 1959.

The training program used technicians acting as instructors and was established for a four-month duration. Training included missile maintenance; SAGE operations and launch procedures, including the launch of an unarmed missile at Eglin.

The last Bomarc missile squadron inactivated on 31 October 1972.  The squadron was inactivated on 30 September 1979.

The Bomarc site is located on Santa Rosa Island is at

Brabag. Brabag (Braunkohle Benzin AG) was a German firm, planned in 1933, and operating from 1934 until 1945, that distilled synthetic aviation fuel, diesel fuel, gasoline, lubricants, and paraffin wax from lignite.  It was an industrial cartel firm closely supervised by the Nazi regime; while it operated, it produced commodities vital to the German military forces before and during World War II.  After substantial damage from strategic bombing, the firm and its remaining assets were dissolved at the end of the war.

History
Brabag, sometimes called 'BRABAG', is a portmanteau acronym () denoting the firm's chief inputs and outputs: brown coal (lignite) and gasoline ('benzine').

Upon the ramp-up of the Nazi program of industrial autarky that marked the approach of war, Berlin saw that one of its weakest points was the almost complete absence of crude oil production within German borders; this insight coincided with the emergence in both Hitler's Chancellery and the General Staff of a belief in a blitzkrieg war-fighting strategy that centered on Panzer warfare, buttressed by warplanes carrying out tactical air support.  This strategy needed synthetic petroleum products.

Berlin therefore, in October 1934, ordered the German chemical conglomerate I.G. Farben to join with a cartel of lignite mineowners and other firms to invest 100.0 million Reichsmarks as an initial tranche of venture capital; these funds were used to set up a new firm, Brabag.  The new firm was ordered to distill gasoline and other synthetic petroleum products, of which Germany had very little, from lignite, of which the Germans had an ample supply.  Chemists had invented the Bergius process and the Fischer-Tropsch process to accomplish this goal.

Soon plants were built.  In 1937, for example, Brabag completed the Brabag II facility in Ruhland-Schwarlheide (the 4th Nazi Germany Fischer-Tropsch plant) to produce gasoline and diesel fuel from lignite coal.

Forced labor 
As Germany deepened its commitment to World War II, Brabag's plants became vital elements of the war effort.  Like other strategic firms under the Nazi regime, Brabag was assigned a significant quota of forced labor of conscripts from the occupied nations.  One estimate counts 13,000 Nazi concentration camp laborers working for Brabag.  Brabag plants were a target of the Oil Campaign of World War II.  Production of synthetic petroleum products had been severely damaged by the end of the war in 1945.

Hornfels in Victorian archaeological sites. Hornfels is an unusual and relatively rare stone used in making flaked stone tools, and which is found in Aboriginal archaeological sites in Victoria, Australia. A sample of places where it has been found can be seen in the geographic section below.

The term has been used for ...a group of compact, fine-grained, metamorphic rocks that form as a result of contact between sedimentary country rocks and a magma intrusion. The mineral composition is variable, but commonly contains mica and pyroxene while porphyroblasts of pyroxene, cordierite or andulusite also develop. Sedimentary structures are rarely evident due to a high degree of recrystallisation.
