Franz Krull Sk class. The Franz Krull Sk-class is a class of steam locomotive built by the Franz Krull metal works of Tallinn, Estonia between 1931-1940.

The Sk were narrow-gauged and used oil shale as fuel, since it is the primary energy source in Estonia. A total of 16 units were produced, of which none has survived. The last Sk, Sk-156, was scrapped in 1980 in Beloretsk, Russia, where it was actively used until scrapping.

Walter Somers. Walter Somers (1839 – 1917) was an English engineer and businessman who established a forge company, later known as Walter Somers Limited, producing a range of steel products including items for military use by the British Admiralty during World War I.

In 1866 Somers was given a loan of £100 by his father and took on a short lease on an ironworks complex at Mucklow Hill, Halesowen, establishing a forgemaster business. Initially focused on production of chains and anchors, the business later also produced axles and railway buffers. By the last decade of the 19th century, it was delivering forgings to Admiralty specifications - a customer relationship that continued throughout World War I. Somers' company also produced parts of the anchors used on the RMS Titanic.

In 1907 Somers bought Belle Vue House on Mucklow Hill, installing electricity in the house. Overhead lines from a generator at Somers' works supplied current for the house until the 1920s when it connected to public services.

Somers died in 1917, leaving the company under the direction of his two sons, Seth and Frank. Frank Somers was managing director until 1954.

Legacy
Walter Somers Limited was incorporated in 1919. However, it became embroiled in the Arms-for-Iraq scandal in the 1980s. 
The business was acquired by the local Folkes Group in the 1990s and the main Mucklow Hill site operates as Somers Forge Ltd. 
The subsidiaries Somers Handling and Somers Vehicle Lifts also still trade in the Halesowen area.

Halesowen town centre was regenerated in the 2000s and the people of the town were given a chance to vote on naming the central pedestrianised area. They chose to name it Somers Square. The family also left legacies of the Somers Sports and Social Club, the Cycling and Athletic Club, the British Legion Club and the Seth Somers Park on which stands the Halesowen Cricket Club.

Tokyo Koku Ki-107. The Tokyo Koku Ki-107 was a Japanese military training aircraft for the Imperial Japanese Army Air Force. The Ki-107 was a wooden-built, low-wing, two-seat monoplane with an open cockpit. Powered by a Hitachi Hatsukaze Ha-47 (Ha-11) inline piston engine, it first flew in October 1943. The Japanese Army had ordered 450, as primary trainers, as replacement for the Kokusai Ki-86 (a license-built Bücker Bü 131 that used the same Ha-47 engine), but production was held up by air raids and only twenty-nine had been delivered by the end of the War.

HMS Wasp (1880). HMS Wasp was a  composite screw gunboat of the Royal Navy, built in 1880 by Barrow Iron Shipbuilding and wrecked off Tory Island in 1884.

Design
The Banterer class was designed by Nathaniel Barnaby, the Admiralty Director of Naval Construction. They were of composite construction, meaning that the iron keel, frames, stem and stern posts were of iron, while the hull was planked with timber. This had the advantage of allowing the vessels to be coppered, thus keeping marine growth under control, a problem that caused iron-hulled ships to be frequently docked.  They were  in length and displaced 465 tonnes. In appearance they were distinguishable from the preceding s (also a Barnaby design) by their vertical stems.

Propulsion
A two-cylinder horizontal compound-expansion steam engine by the builder, Barrow Iron Shipbuilding, provided  through a single screw, sufficient to drive Wasp at .

Armament
Ships of the class were armed with two 6-inch 64-pounder muzzle-loading rifles (a conversion of the smoothbore 32-pounder 58 cwt gun) and two 4-inch 20-pounder breech loading guns. A pair of machine guns were also fitted.

Construction and career
Her keel was laid at Barrow Iron Shipbuilding as yard number 71 and she was launched on 5 October 1880. She was rigged with three masts, making her a barquentine-rigged vessel. Wasp was commissioned on 1 December 1881.

Fate
On her final voyage, Wasp, under the command of Lieutenant J.D. Nicholls, was sailing from Westport, County Mayo, in the West of Ireland, to Moville in Inishowen, County Donegal, in Ulster, to pick up a party of police, bailiffs and court officials, who were to be transported to Inishtrahull Island off Malin Head to carry out evictions for non-payment of rents. The same ship had delivered urgently-needed supplies of seed potatoes to the same islanders the previous year.

In the early morning of 22 September 1884, Wasp was near Tory Island. The weather was cloudy with occasional squalls and rain showers. The commanding officer and most of the crew were in their bunks; the lieutenant navigating the ship was relatively unfamiliar with the area the ship was sailing. At 3:55 a.m. Wasp ran aground on a reef.  The initial shock broke the hull of the ship, and she began to rapidly fill with water. The commander ordered the ship's boats lowered, but Wasp hit the reefs again, sinking so quickly that the boats could not be launched. Within fifteen minutes Wasp had sunk. Six crewmen managed to cling to one of the gunboat's spars; they washed ashore on Tory Island and were found by islanders. The other 52 crew aboard drowned.

A court martial was held for the survivors; the finding was that the cause of the wreck was a lack of care taken with the vessel's navigation, but the survivors were all exonerated. The wreck was sold to the Cornish Salvage Co. in November 1910.

McDonnell XH-20 Little Henry. The McDonnell XH-20 Little Henry is a 1940s American experimental lightweight helicopter designed and built by McDonnell Aircraft.

Development
The McDonnell Model 38 was a lightweight experimental helicopter sponsored by the United States Army Air Force to test the concept of using small ramjets at the tips of the rotor blades. As a functional helicopter it was a simple open-frame steel-tube construction. Allotted the military designation XH-20 the first of two first flew on the 29 August 1947.

Although the XH-20 flew successfully the ramjets were noisy and burnt a large amount of fuel and plans to build a larger two-seat XH-29 were abandoned.

Steen Skybolt. The Steen Skybolt is an American homebuilt aerobatic biplane. Designed by teacher Lamar Steen as a high school engineering project, the prototype first flew in October 1970.

Design and development
The aircraft has a classic structure consisting of a welded tube fuselage and wooden wings, all fabric covered. It is a tandem open-cockpit two-seat biplane and is stressed for normal aerobatics. The cockpits are frequently constructed as a single tandem cabin with an enclosing bubble canopy. Some aerobatic competition aircraft are built as single seaters with the front cockpit closed off.

The original Skybolt had a  Lycoming HO-360-B1B engine, but powerplants of  can be installed.

Operational history
The Skybolt has become popular as an amateur-built sporting biplane, with over 400 aircraft having been completed from construction plans sold in over 29 countries. A Skybolt won the Reserve Grand Champion Custom Built for 1979 at the Experimental Aircraft Association airshow in Oshkosh Wisconsin. Sixteen examples were registered in the United Kingdom in January 2009.

Carputer. A carputer, or car-puter, is a computer with specializations to run in a car, such as compact size, low power requirement, and some customized components. The computing hardware is typically based on standard PCs or mobile devices. They normally have standard interfaces such as Bluetooth, USB, and Wi-Fi. The first carputer was introduced by Clarion on December 4, 1998, although on-board diagnostics have been employed since the 1980s to precisely measure the amount of fuel entering the engine as the carburetors got too complex.

A challenge to installing a computer in a car is the power supply. Energy is supplied as a nominal 12 VDC in cars or 24 VDC in some trucks. The voltage varies according to whether the engine is on or off since the battery generally delivers 12V, while the generator supplies more. There can be peaks, and at ignition time the supply current drops. External DC/DC converters can help to regulate voltages.

Police cars often have Mobile data terminals in the form of a laptop swivel mounted where the driver's armrest would be. This can be used to log data and to query networked databases.

Microsoft developed Windows Embedded Automotive and used it with the AutoPC, a brand of carputer jointly developed with Clarion. The system was released in 1998, and referred to the operating system itself as "Auto PC". It was based on Windows CE 2.0. It evolved into "Windows CE for Automotive". The platform was used for the first two generations of MyFord Touch while the third generation runs QNX from BlackBerry Limited.

Tablet computers such as the Nexus 7 can be installed either permanently (in-dash) or removably (a dock).  They can be used for watching movies or listening to music, as well as for GPS navigation, and also have Bluetooth for hands-free calls.

Computers can be used to decode on-board diagnostics (OBD) data to a visual display. Many interfaces are based on the ELM327 OBD Interpreter ICs. STN1110 is also known to be used.
