TradElect. TradElect was the London Stock Exchange's main electronic trading platform from 2007 to 2011. It ran on HP ProLiant servers running Windows Server 2003, using .NET technology and Microsoft SQL Server 2000. Its development took four years from project inception to rollout and had a total cost of £40 million.

The impetus for the development of TradElect was the rise of algorithmic trading and the liberalisation of the trading sector in Europe due to the Markets in Financial Instruments Directive. Both of these factors meant that stock exchanges – previously facing little or no competition – had to offer faster response times to be competitive. The system which TradElect replaced, Sets, was 10 years old and took 140 ms to complete a trade, compared to TradElect's 10 ms. Infolect, an integrated part of TradElect, is used for dissemination of market data.

In April 2010 the Oslo Stock Exchange also adopted TradElect, as part of a strategic partnership agreement. The Johannesburg Stock Exchange also adopted TradElect.

Downtime
On 8 September 2008, TradElect trading was mostly unavailable for over 7 hours, on what the Wall Street Journal described as a "huge trading day". Traders walked out of the London Stock Exchange in protest. Another major technical fault had occurred less than a year earlier.

The London Stock Exchange claimed that the TradElect software was not to blame, instead blaming an unspecified fault with "network software". However, Celent analyst Cubillas Ding noted that this outage, and three previous ones, all coincided with large spikes in trading volumes, from different economic events, and concluded that the LSE's technology could not cope with the high trading volumes.

Microsoft had previously used TradElect as a case study in marketing material to position its Windows operating system as suitable for "highly reliable" systems. It did not respond to requests for comment.

Successor 
In May 2009, the London Stock Exchange gained a new CEO, Xavier Rolet, who set about reviewing costs and cutting jobs. Only two years after TradElect had first gone live, the London Stock Exchange decided to scrap it and replace it with something else. The LSE investigated the possibility of building a new system in-house, but eventually decided on acquiring the existing, Linux-based system Millennium Exchange, which had a lower, sub-millisecond latency. It acquired this system by acquiring the company that created it, MillenniumIT, in 2009, for £18 million. In its annual report, the LSE said that it expected the switch to Millennium Exchange to save $16 million per year starting from the 2012 financial year.

By 2011, TradElect had been completely replaced with Millennium Exchange at the London Stock Exchange.

The Oslo Stock Exchange and the Johannesburg Stock Exchange also switched to Millennium Exchange.

Max B. Harlow. Max B. Harlow (1903 –1967) was an American aircraft engineer, educator, and producer.

Early life 
Harlow was born in South Dakota in 1903. Harlow attended Stanford University, becoming an early aircraft engineering graduate. His first position was with Thaden Metal Aircraft Company to develop an early all-metal aircraft, the Thaden T-1. He assisted Waldo Waterman in the design and construction of the prototype Waterman Whatsit tailless aircraft. Waterman was chief test pilot for Bach Aircraft and brought Harlow in to improve the design of the Bach Air Yacht trimotors. Harlow also worked for a brief period in 1930 for Lockheed Brothers Aircraft Corporation on the Olympia Duo-four wooden aircraft. In 1932, Harlow worked for Bert Kinner becoming his chief engineer in the design of the Kinner Playboy, Sportwing, and Speedwing. When Kinner's company folded in 1934, he went to work for Douglas and a stress engineer for the DC-2 wing.

Harlow became a professor at Pasadena Junior College in 1935 forming the Aero-Tech laboratory. While a professor, he was able to join the local Hollywood engineering team developing the Hughes H-1 Racer which would lead to future business connections. As a student project, the college developed the Harlow PJC-1. Harlow formed the Harlow Aircraft Company at the Alhambra Airport to commercially build the PJC "Pasadena Junior College" series of aircraft and military trainers. From 1936-1942 students worked on designing and producing a series of advanced all-metal retractable gear lightplanes under Harlow's supervision. Funding came from former Howard Hughes business partner J.B. Alexander. The aircraft were tested at the airstrip at Alhambra, California.

Chesapeake and Ohio class M-1. The Chesapeake and Ohio class M-1 was a fleet of three steam turbine locomotives built by the Baldwin Locomotive Works for the Chesapeake and Ohio Railway in 1947–1948 for service on the Chessie streamliner. As diesel locomotives became more prevalent following World War II, the C&O was one of several railroads that were reluctant to abandon coal as a fuel source, and saw steam turbine technology as a possible alternative to diesel. At the time of its construction it was the longest single-unit locomotive in the world.

Design 
The design of the M-1 was a collaboration between the C&O, the Baldwin Locomotive Works and Westinghouse. The C&O possessed substantial coal-hauling revenue and was loath to abandon it as a fuel source. Further, C&O's engineering staff expressed concern that oil reserves would be exhausted within 25-30 years. The locomotive contained a single Westinghouse turbine which in turn drove four direct current (DC) generators, mounted in pairs. Each generator produced , and the four generators collectively turned eight traction motors.

Defying the usual convention, the M-1 was arranged with its boiler in the rear and the coal bunker in the front. The turbine-generator system meant that the M-1 contained no cylinders. The reduced number of moving parts meant that, in theory, the M1 required far less maintenance than a conventional steam locomotive. Its designers predicted that it could make a round trip between Washington and Cincinnati without servicing.

The locomotive's throttle included eleven settings, ranging from one (idling) to eleven (full speed). The locomotive's cruising speed was , at which point the throttle was on "seven." During a trial run with a reporter from Popular Mechanics aboard, a C&O engineer expressed his dissatisfaction with a local speed limit of , noting that he would "sure like to be able to pull it back to eleven!" Not including research and development, the three locomotives cost .

Career 
The C&O cancelled the Chessie in 1948, before it ran in revenue service, depriving the M-1s of their reason for existence. The M-1s themselves proved expensive to operate and mechanically unreliable. They spent their short careers operating between Clifton Forge and Charlottesville, Virginia. The locomotives were scrapped in 1950.

Hindi film distribution circuits. Hindi film distribution circuits comprise territories which have been created by film distributors for releasing Hindi cinema or Hindustani cinema (as it was earlier known) across India. The six distribution circuits were created in 1930s after the advent of the first talkie in 1931. These circuits were:

 Bombay circuit
 Eastern circuit
 Delhi-U.P. circuit,
 C.P.-C.I.-Rajasthan circuit
 Punjab circuit
 South circuit

Presently territories for distribution of Hindi films are divided into eleven territories. These are.

Amongst the above territories Bombay circuit is considered by the distributors as having potential for maximum earnings. An additional territory known as overseas territory also exists. However, Hindi movies in Nepal & Bhutan are released by distributors through the Eastern circuit.

Bazzocchi EB.1 Littore. The Bazzocchi EB.1 Littore () was a one off, Italian single seat trainer glider designed and built by a university student in 1936.

Design and development
Ermanno Bazzucchi was a nineteen-year-old student at the Polytechnic University of Milan when he designed and built the EB.1.  Friends from the University Fascist Group helped with its funding.  It was intended as a simple and low cost single seat trainer glider.

The EB.1 was a high wing braced monoplane with a wooden structure and skinned with a mixture of plywood and fabric.  Its wings were built around two spars and were aerodynamically thick; in plan they were unswept and of parallel chord, ending in asymmetrical elliptical tips.  Ailerons filled about half the span. Mounted with about 2° of dihedral, they were braced to the fuselage on each side by a parallel pair of faired wooden struts which ran from the bottom of the fuselage to the wings at about one third span.

The EB.1 had a deep sided, hexagonal cross section fuselage, ply covered forward and fabric aft.  Its cockpit, immediately ahead of the wing, was open but the pilot was partly sheltered by a long streamlined transparency which photographs show to have been modified at least once.  The tail surfaces were elliptical, the fin tall and the rudder extending down to the keel.  Its cantilever tailplane, set at mid fuselage, was fabric covered and carried  balanced elevators well separated to allow the rudder to move between them.  A long, simple sprung skid served as the undercarriage.

The EB.1 first flew in 1936 from a hill near Cantù, elastic rope launched and piloted by Bazzocchi.  Only one was built.

Operational history
Bazzocchi flew the EB.1 in the National University Contests (the Littoriali), held at the Cantù site. It later flew at Taliedo and Tradate.

Interlocking machine room. An Interlocking machine room (IMR) is a component of the London Underground signalling system. Interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. On the London Underground signals and points are operated and controlled by an array of electrical, pneumatic and mechanical components. IMRs are unmanned and generally located adjacent to points or at platform ends, and provide a secure and weatherproof enclosure for pneumatically controlled mechanically and electrically interlocked levers mounted horizontally in an upright lever-frame or with a converted manual lever frame.
 

The table below is an alphabetical listing of the extant Interlocking Machine Rooms on the London Underground network in August 2024.

As London Underground train control is modernised and updated some Interlocking Machine Rooms are made redundant. The table below is an alphabetical listing of the IMRs on the London Underground network that were operational in 1994 but had been decommissioned by August 2024.
