Barr Construction. Barr Construction was a major Scottish contracting organisation operating throughout the United Kingdom.

History 
The company started in the late 19th century as a joinery firm known as W & J Barr & Sons and gradually expanded into civil engineering projects.  As Barr began to grow its operations out of its native Ayrshire and into larger civil engineering developments, it decided to incorporate in 1976.

The company's stadia work included new facilities for Southampton, Fulham, Celtic, and Rangers football clubs as well as projects for lower league and rugby clubs. Clubs which got into financial difficulty because of mounting debts to the company included Airdrieonians and Raith Rovers. 

In 2001 the company won the contract to upgrade the A830 road between Mallaig and Fort William in the Scottish highlands. Barr were also involved in the renovation of Home Park, the stadium home of Plymouth Argyle.

In 2006 Barr built the first "eco-store" for Tesco at Wick in Scotland, using the unorthodox method of ship transport to deliver building materials to the site in order to save on carbon emissions.

In 2007 the company was bought by McLaughlin & Harvey.

For the 2012 London Olympic games, Barr won the contract to construct the Olympic Park Basketball arena.

In November 2014 McLaughlin & Harvey integrated Barr Construction into its business and Barr Construction ceased to exist as a separate business, although the Barr name continues to be used within the group for Barr Environmental.

Overcurrent. In an electric power system, overcurrent or excess current is a situation where a larger than intended electric current exists through a conductor, leading to excessive generation of heat, and the risk of fire or damage to equipment. Possible causes for overcurrent include short circuits, excessive load, incorrect design, an arc fault, or a ground fault. Fuses, circuit breakers, and current limiters are commonly used overcurrent protection (OCP) mechanisms to control the risks.
Circuit breakers, relays, and fuses protect circuit wiring from damage caused by overcurrent.

Overcurrent in an electrical grid 
Overcurrent capabilities of electrical generators are essential for the power system operations. Lack of overcurrent capability (low short circuit ratio) of a weak grid creates a multitude of problems, including: 
 transients during the large load changes will cause large variations of the grid voltage, causing problems with the loads (e.g., some motors might not be able to start in the undervoltage condition);
 the grid protection devices are designed to be triggered by a sufficient level of overcurrent. In a weak system the short circuit current might be hard to distinguish from a normal transient overcurrent encountered during the load changes;
 during a black start operation after a failure, large inrush current might be needed to energize the system components. For example, if some loads in a weak system remain connected, and inverter-based resource might not be able to start.

Yacht XV 1. The 42' sailboat known as the XV/1 was intended to demonstrate Haveblue LLC's patented technology for the production, storage, and use of hydrogen on board a marine vessel. The anticipated range was to be a radius of ~300 nautical miles at  on a full tank.

XV/1 System Configuration

 Two solar panels producing ~600 watts at peak
 A marine wind generator producing ~90 watts at peak
 A regenerative electric drive motor capable of producing ~500 watts while under-sail
 A reverse-osmosis water-maker
 A hydrogen-generator using the electrolysis of water
 Hydrogen storage, either metal hydride or lightweight composite pressurized tanks
 10-kilowatt PEM fuel cell
 Twelve 12v AGM batteries in a 144v, 105Ah bank
 Three house batteries, 12v parallel

XV/1 Outcome
Management issues at Haveblue LLC prevented the completion of the XV/1 project.

Technology overview 

The technology allows a marine vessel to be fully self-sustaining, without the need for fossil fuels. It uses technologies well known in the marine environment, such as solar panels, wind turbines, reverse osmosis water-makers, marine batteries, and regenerative electric motors in conjunction with fuel cells and the electrolysis of water. 
It eliminates engine noise, vibration, exhaust fumes, and the risk of fuel spills that threaten our air and waters.

 A marine vessel obtains water from where it happens to be afloat (if necessary, it can also obtain water from a public utility).
 The "water-maker" processes the water to the required level of purity.
 The electrolysis unit produces hydrogen and oxygen from the purified water.
 The hydrogen is stored for use by a variety of power-plants, from fuel cell stacks to internal combustion engines.
 The hydrogen-consuming power-plant provides energy for propulsion and/or supplies the vessel's onboard energy needs (the hydrogen can also be utilized to reduce emissions produced by internal combustion engines).

Whether docked, moored, or underway, the renewable energy resources of a boat provide the electricity needed to continuously produce hydrogen via electrolysis for immediate use or stored for use later. If shore power is available, it may also be used for the hydrogen production and storage process.

Bioluminescent activated destruction. Bioluminescent activated destruction or BLADe refers to a technique used to kill cancer cells.

It works by first altering the cells in an organism, once they become cancerous, to create the firefly light source luciferin and luciferase to create light.  The light itself would have little effect on the cells if it wasn't for the addition of a photosensitizing agent which essentially makes the cells much more vulnerable to light. It can specifically eradicate the cancer cells with no negative side-effects to normal cells. Trials on humans have yet to be seen, although the trials on mice looked rather promising for it.

Wind-up toy. A wind-up toy is an automaton toy powered by a clockwork motor.

Background

Automata built for the sake of art, amusement, and simulation have been described since antiquity, in cases such as Heron of Alexandria designing clockwork birds during the Hellenistic Period. Leonardo da Vinci is frequently credited with constructing a mechanical lion, which he presented to King Francois I in Lyon in 1515. Although no record of the device's original designs remain, a recreation of this piece is housed at the Château du Clos Lucé.

Some misinformation exists with regards to Regiomontanus's contribution, and his supposed construction of a flight-capable mechanical eagle and fly, which are frequently credited as the first wind-up toys. This story of an eagle which flew from Nuremberg to greet Friedrich III, alongside that of a fly which could circulate the room before returning to its inventor's hand, was spread by Petrus Ramus after a visit to Nuremberg in 1571, and is apparently false. Furthermore, various internet sites instead credit these inventions to a Karel Grod, but little evidence suggests he exists.

René Descartes may have attempted to build some automata. According to legend, a life-sized wind-up human girl was discovered in his luggage aboard a ship in which he was traveling to Sweden, and was thrown overboard by order of the ship's Captain.

History
After the larger, elaborate wind-up machine art declined in interest, wind-up toys were created cheaply in large numbers by the 1800s. Wind-up machines became known as wind-up toys, and were designed in different forms to move around. European toy makers created and mass-produced the first wind-up tin toys during the late 1880s. Over the next 60 to 70 years, more manufacturers created more intricate designs. The trend stopped with the introduction of the small and inexpensive Alkaline battery in the 1960s, which allowed motors to run without a wind-up mechanism. Over the next 20 years, wind-up toys lost popularity.

Plastic wind-ups started in 1977 when the Japanese company Tomy made a walking Robot (Rascal Robot). Tomy's ability to build small precise plastic gears and parts allowed them to reduce the size of the gearbox (housing the spring drive).

FL-boat. The FL-boat (Fernlenkboot, literally "remote controlled boat") was a weapon used by the Imperial German Navy during World War I. It was a remote-controlled motorboat, 17 m long, carrying  of explosives, which was intended to be steered directly at its targets - initially the Royal Navy monitors operating off the coast of Flanders.

FL-boats were constructed by Siemens-Schuckertwerke.  They were driven by internal combustion engines and controlled remotely from a shore station through spooled wire unwound behind the boat. The wire was  long and the spool weighed . An aircraft could be used to signal directions to the shore station by radio. The commands available to the boat operator were:

 System test
 Engine start, engine stop
 Set Rudder position
 Turn on a light, to enable the boat to be tracked at night
 Detonate the warhead, to prevent capture of the boat if it missed its target

Planned developments were to use a control station carried on a ship, in an airship or use a radio-control system. The boats could attain speeds of .

On 1 March 1917 an FL-boat hit the Nieuwpoort mole and on 28 October 1917 one hit the Royal Navy monitor HMS Erebus.

Bharat Pumps & Compressors. Bharat Pumps & Compressors Limited (BPC) is a central public sector undertaking under the ownership of Ministry of Heavy Industries, Government of India. The psu manufactures Reciprocating pumps, Centrifugal pumps, Reciprocating compressors, and high pressure seamless Gas cylinders.  Headquarters in Prayagraj.

History
BPC was set up in 1970 to cut the country’s dependence on import of hi-tech equipment like pumps and compressors for use in critical areas like oil & gas exploration, refineries, chemical & fertilizer plant and nuclear plants. Unfortunately, the company was unable to make profits. Eventually, it turned sick and was referred to the Board for Industrial and Financial Restructuring (BIFR). BPC’s losses had accumulated to  as on 31 March 2005 and the net worth had turned negative at . The company was referred to the BIFR and was on the verge of being closed down after 35 years of operations.

The company has seen a dramatic turnaround in its performance from the financial year 2005-06. The company’s profit before tax (PBT) in the financial year 2006-07 was , which increased to  in 2009-10. During the same period, its net worth increased from  to . The turnover went up to  in 2009-10 from  in 2006-07.
The turnaround of the company is credited to Abhay Kumar Jain, who was appointed the MD of the sick company in the year 2005-06. The special efforts and corporate strategies put in place by Jain, after joining on 31.12.2005, yielded the much awaited turnaround of the Company. BPCL achieved a net profit of ₹1.84 crores during Financial Year 2005-06 after accounting for interest amounting to ₹135 million as against a loss of ₹108.6 million during previous year 2004-05. This remarkable feat of turnaround is of significance since it was achieved without considering the benefits of financial restructuring.
Presently, the company is again running in loss. Jain invested nearly ₹100 crores in purchase of new machines and had projected business of ₹1600 crores but this target was never achieved and as a result, company incurred loss.

On the 28th of September 2016, the Government of India announced the privatization of Bharat Pumps & Compressors. On 17 April 2018 the Government of India issued an Expression of Interest for a 100% stake in Bharat Pumps & Compressors.

On the 14th of Jan 2021, the Government of India announced the liquidation of Bharat Pumps & Compressors.

Mitsubishi Pedion. The Pedion was a subnotebook computer developed by Mitsubishi Electric with Hewlett-Packard in 1998. Hewlett-Packard marketed a rebadged version of the Pedion under their OmniBook brand of notebooks and subnotebooks, called the OmniBook Sojourn, in the same year. Mitsubishi's subnotebook is named after the Greek word pedion (πεδίον), meaning "plain", "flat", "field".

At  thick, the Pedion was the thinnest notebook computer in the world, even thinner than 2008's MacBook Air ; the MacBook Air was 4 mm at its thinnest point, however. The Pedion included a Pentium MMX processor clocked at 233 MHz, 64 MB of RAM, and a 1 GB hard disk drive.

The Pedion was the first laptop on the market to feature an island-style keyboard—a design for laptop keyboards in which they contain scissor-style switches with low travel and simplified flat keycaps separated from each other by a plastic bezel. This style of keyboard technology would not proliferate on laptop keybords until nearly a decade later.

Mitsubishi ceased production and withdrew the notebook from the market due to "mechanical problems".
