Falcon 9 flight 10. Falcon 9 flight 10 was a Falcon 9 space launch that occurred on July 14, 2014. It was the fifth launch of the Falcon 9 v1.1 launch vehicle and carried six Orbcomm-OG2 telecommunication satellites. All six  satellites were successfully deployed.

Following the first stage loft of the second stage and payload on its orbital trajectory, SpaceX conducted a successful flight test on the spent first stage that received considerable news attention. In the event, the first stage successfully decelerated from hypersonic speed in the upper atmosphere, made a successful reentry, landing burn, and deployment of its landing legs and touched down on the ocean surface. The first stage was not recovered however as the hull integrity was breached on landing or on the subsequent "tip over and body slam".

History

This launch schedule was particularly problematic and was delayed several times, with success on the fourth scheduled launch attempt on July 14, 2014.

Earlier launch attempts were:
delayed by SpaceX due to a first stage helium leak
delayed by Orbcomm due to a potential defect in one of their satellites. On June 20 a launch attempt was scrubbed due to a fluctuation in pressure readings on the second stage.
delayed one day by weather on June 21 when the launch window was closed due to poor weather conditions on the flight trajectory through the lower atmosphere
the June 22 attempt was scrubbed by SpaceX to address a potential concern with the launch vehicle identified during pre-flight checks.

Post-mission launch vehicle testing

In an arrangement unusual for launch vehicles, the first stage of the SpaceX Falcon 9 rocket conducted a propulsive-return over-water test after the second stage with the Orbcomm OG2 payload separated from the booster.

This was the third high-altitude post-mission test of this type, after the first test on Falcon 9 Flight 6 in September 2013,
and a second test in April 2014. The April test resulted in the first successful controlled ocean soft touchdown of a liquid-rocket-engine orbital booster
and included landing legs for the first time which were extended for the simulated "landing".

Bis(dinitrogen)bis(1,2-bis(diphenylphosphino)ethane)molybdenum(0). trans-Bis(dinitrogen)bis[1,2-bis(diphenylphosphino)ethane]molybdenum(0) is a coordination complex with the formula Mo(N2)2(dppe)2.  It is a relatively air stable yellow-orange solid.  It is notable as being the first discovered dinitrogen containing complex of molybdenum.

Structure
Mo(N2)2(dppe)2 is an octahedral complex with idealized D2h point group symmetry.  The dinitrogen ligands are mutually trans across the metal center.  The Mo-N bond has a length of 2.01 Å, and the N-N bond has a length of 1.10 Å.  This length is close to the free nitrogen bond length, but coordination to the metal weakens the N-N bond making it susceptible to electrophilic attack.

Synthesis
The first synthetic route to Mo(N2)2(DPPE)2  involved a reduction of molybdenum(III) acetylacetonate with triethylaluminium in the presence of dppe and nitrogen.

A higher yielding synthesis involves a four-step process. In the first step, molybdenum(V) chloride is reduced by acetonitrile (CH3CN) to give [MoCl4(CH3CN)2]. Acetonitrile is displaced by tetrahydrofuran (THF) to give [MoCl4(THF)2]. This Mo(IV) compound is reduced by tin powder to [MoCl3(thf)3]. The desired compound is formed in the presence of nitrogen gas, dppe ligand, and magnesium turnings as the reductant:

 3 Mg  +  2 MoCl3(THF)3  +  4 Ph2PCH2CH2PPh2  +  4 N2  →  2 trans-[Mo(N2)2(Ph2PCH2CH2PPh2)2]  +  3 MgCl2 + 6 THF

Reactivity
The terminal nitrogen is susceptible to electrophilic attack, allowing for the fixation of nitrogen to ammonia in the presence of acid.  In this way, Mo(N2)2(dppe)2 serves as a model for biological nitrogen fixation.  Carbon-nitrogen bonds can also be formed with this complex through condensation reactions with ketones and aldehydes, and substitution reactions with acid chlorides.  The terminal nitrogen can also be silylated.

Mersey Match Factory. The Mersey Match Factory, later known as The Matchworks, is a former match factory on Speke Road, Garston, Liverpool, England.  The factory closed in 1994, and has since been converted into offices and workshops.  It had opened in 1921, having been built for Maguire, Paterson and Palmer, and later used by Bryant and May.  The factory was the first building in the United Kingdom to be constructed using the flat-slab concrete technique.  It is recorded in the National Heritage List for England as a designated Grade II listed building.

Early history

The factory was built between 1919 and 1921 for the match producing firm of Maguire, Paterson and Palmer.  The company had been founded in 1898 by J. T. Maguire and his four sons, who had previously worked for the Diamond Match Works in Liverpool.  By 1919 J. T. Maguire and two of the sons had died, and another son had retired, leaving only Alexander Maguire to run the company, which then became Maguire, Paterson and Palmer.  In 1923 it became part of Bryant and May. The factory was taken over by Swedish Match in 1987, but it closed on 21 December 1994.

Since 1999 work has been carried out on the former factory buildings by the developers Urban Splash with the architects ShedKM.  The factory has been transformed into offices, with service pods added to the rear, and a new mezzanine floor has been inserted.  The former service wing at the rear has been converted into offices and workshops, and the Neo-Georgian block between the factory and Speke Road has been demolished.

Architecture

The factory was designed by Mewès and Davis in conjunction with the structural engineer Sven Bylander.  The factory range was constructed of reinforced flat-slab concrete; it was the first building in the United Kingdom to use this technique.  The service wing is in brick. The former factory wing is in two storeys, it has a front of thirty-five bays, and is three bays deep.  It is constructed as a concrete frame on a brick plinth, the frame being filled with glass.  The columns are decorated with Lancashire roses, and between the storeys is a band of coloured tiles.  On the roof is a cylindrical water tower with a pointed top.  On the rear of the range are six silver-coloured corrugated cylindrical service pods with slot windows. The former service range extends for sixteen bays and is three bays deep, with an extension of thirteen bays, one bay deep.  Inside the former factory are two arcades of circular columns with mushroom-shaped heads and square-shaped bearing pads.  There are concrete staircases in the middle of the building and at the ends.

Appraisal

The former factory was designated as a Grade II listed historic building on 17 February 1998. Grade II is the lowest of the three grades of listing, and includes buildings that "are nationally important and of special interest".

Daniel R. von Recklinghausen. Daniel R. von Recklinghausen (January 22, 1925, New York City – August 22, 2011) was an electrical engineer. 

He graduated from Massachusetts Institute of Technology in 1951 with a Bachelor of Science degree in Electrical Engineering. He was a member of Tau Beta Pi, Sigma Xi, and Eta Kappa Nu fraternities.

Daniel (or DVR as he was known) was recruited straight out of MIT by Hermon Hosmer Scott, who was a professor of electrical engineering at MIT, as a chief research engineer. (However, there was little doubt that DVR was in every sense, the chief engineer.)  Von Recklinghausen was immediately put to work on the redesign of the Scott 310 FM tuner.  All subsequent tuners, are in electronic terms, "DVR designs." Daniel also worked closely with Fairchild Semiconductors, and made extensive use of its product line, or whatever Robert Noyce suggested might work, as HH Scott transitioned to the use of IC's in its intermediate frequency stages, in mid 1965.

It was the work with Noyce and Fairchild that led to Von Recklinghausen's patent in FET intensification.  

As the fortunes of HH Scott declined, Von Recklinghausen's final effort for the company was to design a line of products that could be manufactured in Japan.  It was too little, too late to save the company from receivership.  

HH Scott Inc., was purchased outright by its Belgian licensee in 1973. (The company was eventually sold to Emerson Electronics.)  At that time, Von Recklinghausen began working closely with Advent on the design of the FM tuner that was featured in its popular Advent 300 Receiver.

Von Recklinghausen later worked at Electro Audio Dynamics, beginning in 1973. In 1975, he was appointed Vice President of Research and Development for KLH, where he patented computer controlled loudspeakers. He was a member of the National Stereophonic Radio Committee. He served the Audio Engineering Society (AES) as president in 1967, and was the journal editor from 1991-2004. 

Von Recklinghausen was an author of numerous articles and publications, and held 24 patents. He was also an avid photographer.

SARbot UK. SARbot UK is an underwater search and rescue charity based in the United Kingdom. They can be called to assist the emergency services who are unable to perform rescues below the water's surface. These services often have to call for divers who do not operate on an immediate response system. Where available the SARbot team aim to be on the scene and searching underwater within 90 minutes. Within this time it remains possible to resuscitate a person. The organisation hopes to set up bases across the country to cover a wider area.

Technology
The robots used by the charity are remote controlled and feature sophisticated image enhancers that, according to the operators, can give "a 120 meter view in zero visibility". The robots are capable of pulling a body out of the water using a grabbing arm. Some of the equipment is on loan from Seabotix. Each robot costs up to £140,000.

Underwater search dogs
A recent collaboration with International Rescue Training Centre Wales (IRTCW) has seen the introduction of search dogs capable of detecting the presence of human remains underwater. The dogs work from a boat and sniff the water; they are able to detect the scent of human remains and indicate to the handler. The handler then calls in SARbot to perform the recovery.

Notable searches
The charity assisted the Metropolitan Police in their search for murdered EastEnders actress Gemma McCluskie. They were called in to help divers search around  of the Regent's Canal in Hackney where parts of her body had been found. This was the first case of such underwater robots being used in London.

In April 2012 the charity were called to assist West Midlands Police and Fire Service, after a 5-hour search in a lake at Sutton Park, Birmingham by divers and swift water rescue technicians SARbot were asked to assist. Upon arrival the robot was deployed and the team discovered the body within 10 minutes.

SARbot also assisted in the search for Sascha Schornstein, a pilot who crashed in the English Channel in July 2013. Schornstein was flying from Hampshire to Le Touquet in a light aircraft when it crashed into the water. Initial reports suggest that this was attempt to fake his own death. A number of volunteers from SARbot hired a catamaran and used their equipment to search for any signs of Schornstein's body. They identified the crash site and the robots have taken images of what is believed to be the plane's fuselage, with a more detailed search needed to confirm the possible presence of a body.

The team were also called to assist in the 2012 search for April Jones.

Collins X-112. The Collins X-112 was an experimental two-seat ground-effect vehicle, designed by Alexander Lippisch in the United States in the early 1960s to test his thick reverse delta wing concept.

Design and development
Lippisch's development of his Aerofoil Boat, a ground-effect vehicle for use over water, began whilst he was working in the aviation division of the Collins Radio Company in Cedar Rapids, Iowa, US. The Collins X-112 was built to test the concept.

The Airfoil Boat was an inverse-delta aircraft, that is, it had a wing which was triangular in plan but with a straight, unswept leading edge. Combined with strong anhedral, this layout produces stable flight in ground effect. Specifically, it is claimed that it is stable in pitch and also that it can fly in ground effect at altitudes up to about 50% of its span, allowing it to operate over rough water. This contrasts with the lower-aspect-ratio square wing of the ekranoplans, which leaves ground effect at only 10% of span, limiting them to the calmer waters of lakes and rivers.

Its fuselage was conventional, with flat sides and rounded decking. The nose-mounted single engine was of very low power, only . Two open cockpits were arranged in tandem, both over the wing. Aft of the trailing edge root the bottom of the fuselage rose strongly to carry a tall, broad fin and rudder. The X-112 had a T-tail, carrying elevators. Its thick airfoil wings were low-mounted, each with a tip float or "pontoon", which in combination with the strong anhedral kept the fuselage well clear of the water surface. Each float carried a winglet fitted with an aileron for roll control. A retractable water-rudder, fuselage-mounted at the point at which the lower fuselage rose upwards, provided directional control on the water surface.

Tests made during 1963 began with the Airfoil Boat operated like any fast motor boat, planing on the surface. With speeds increased to around  the X-112 rose clear of the surface as a ram-air air cushion or ground-effect vehicle. Solo free flights at up to  were made; tests with two occupants were also conducted. "Entirely satisfactory" stability and control characteristics were reported under all these conditions.  With the Airfoil Boat proved, the X-112's mission was completed, and Lippisch, suffering from cancer, left Collins Radio. He recovered sufficiently to design and build its successor, the fibreglass, more powerful X-113 with Rhein-Flugzeugbau GmbH in Germany.
