Ballpoint
A ballpoint pen, also known as a biro (British English), ball pen (Hong Kong, Indian and Philippine English), or dot pen ( Nepali) is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e. over a "ball point". The metal commonly used is steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre. Some pen manufacturers produce designer ballpoint pens for the high-end and collectors' markets. History Origins The concept of using a "ball point" within a writing instrument to apply ink to paper has existed since the late 19th century. In these inventions, the ink was placed in a thin tube whose end was blocked by a tiny ball, held so that it could not slip into the tube or fall out of the ...

Ballpoint Pen Artwork
Since their invention and subsequent proliferation in the mid-20th century, ballpoint pens have proven to be a versatile art medium for professional artists as well as amateur doodlers. Ballpoint pen artwork created over the years have been favorably compared to art created using traditional art mediums. Low cost, availability, and portability are cited by practitioners as qualities which make this common writing tool a convenient, alternative art supply. Ballpoint pen enthusiasts find the pens particularly handy for quick sketch work. Some artists use them within mixed-media works, while others use them solely as their medium-of-choice. The medium is not without limitations; color availability and sensitivity of ink to light are among concerns of ballpoint pen artists. The internet now provides a broad forum for artists to promote their own ballpoint creations, and since its inception ballpoint pen art websites have flourished, showcasing the artwork and offering information of th ...

Dip Pen
A dip pen or nib pen or pen nib usually consists of a metal nib with capillary channels like those of fountain pen nibs, mounted in a handle or holder, often made of wood. Other materials can be used for the holder, including bone, metal and plastic; some pens are made entirely of glass. Generally, dip pens have no ink reservoir, so the user must recharge the ink from an ink bowl or bottle to continue drawing or writing. There are simple, tiny tubular reservoirs that illustrators sometimes clip onto dip pens, which allow drawing for several minutes without recharging the nib. Recharging can be done by dipping into an inkwell, but it is also possible to charge the pen with an eyedropper, a syringe, or a brush, which gives more control over the amount of ink applied. Thus, "dip pens" are not necessarily dipped; many illustrators call them "nib pens". Dip pens emerged in the early 19th century, when they replaced quill pens and, in some parts of the world, reed pens. Dip pens were ...

Mechanical Pencil
A mechanical pencil, also clutch pencil, is a pencil with a replaceable and mechanically extendable solid pigment core called a "lead" .

Other names include: microtip pencil, automatic pencil, drafting pencil, technical pencil, click pencil (generally refers to a specific brand), pump pencil, leadholder, Pacer (Australian English, ca. the 1980s), propelling pencil (British and Australian English, often refers to higher-end mechanical pencils), pen pencil (Indian English), and lead pencil (Bangladeshi and American English). Mechanical pencils are used to provide lines of constant width, without need of sharpening, for tasks such as technical drawing as well as for clean looking writing. They are also used for fine-art drawing. Since they do not have to be sharpened, they are also popular with students. Mechanical pencils were first u ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

Miles Aircraft
Miles was the name used between 1943 and 1947 to market the aircraft of British engineer Frederick George Miles, who, with his wife – aviator and draughtswoman Maxine "Blossom" Miles (née Forbes-Robertson) – and his brother George Herbert Miles, designed numerous light civil and military aircraft and a range of curious prototypes.

In 1929 they opened Woodley Aerodrome, near the town of Reading, Berkshire. In 1936, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of the Miles Messenger and to do so it took over a former linen mill in Banbridge, County Down, Northern Ireland for the production of components of the aircraft.
