Inglefield Clip
The Inglefield clip (also known as a sister clip and a Brummel hook) is a clip for joining a flag or ensign quickly, easily and securely to flag halyards so that the flag can be hoisted. They are also used for jib sheets on small boats and to connect the speed line in paragliders. Each clip resembles a link of chain, with a split through one side. The edges of this split are chamfered, so that the clips can be engaged or disengaged, but only if they are carefully aligned by hand. When pulled tight, the links are securely fastened. There are no moving parts to the link, although some have additional swivel pieces. They can be made of any durable material; commonly brass, bronze, stainless steel or plastic. The clips come in two basic types: 'standard' with the halyard attached directly to the clip, and 'swivel' which incorporates a rotational connector so that the halyard can rotate without affecting the flag. In the Royal Navy a flag or ensign normally has both types of clip, one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Malta Dockyard
Malta Dockyard was an important naval base in the Grand Harbour in Malta in the Mediterranean Sea. The infrastructure which is still in operation is now operated by Palumbo Shipyards. History Pre-1800 The Knights of Malta established dockyard facilities within the Grand Harbour to maintain their fleet of galleys. These were spread between the cities of Senglea, Cospicua and Vittoriosa. 19th century When Malta became a British protectorate in 1800, these facilities were inherited, and gradually consolidated, by the Royal Navy. With the loss of Menorca, Malta swiftly became the Navy's principal Mediterranean base. The Royal Navy Dockyard was initially located around Dockyard Creek in Bormla, and occupied several of the dockyard buildings formerly used by the Knights of Malta. By 1850 the facilities included storehouses, a Ropewalk, ropery, a small steam factory, Victualling Commissioners, victualling facilities, houses for the officers of the Yard, and most notably a dry dock&n ...

HMS Melita (1888)
HMS ''Melita'' was a Royal Navy ''Mariner''-class composite screw sloop of 8 guns, launched in 1888 and commissioned in 1892. She was the only significant Royal Navy warship ever to be built in Malta Dockyard,Two 2-gun 94-ton schooners were also built by German of Malta in the 1850s She was renamed HMS ''Ringdove'' in 1915 as a salvage vessel and in 1920 was sold to the Falmouth Docks Company, which changed her name to ''Ringdove's Aid''. She was sold again in 1926 to the Liverpool & Glasgow Salvage Association, renamed ''Restorer'', and finally broken up in 1937, 54 years after her keel was laid. Construction The last of six 8-gun ''Mariner''-class gunvessels designed by Nathaniel Barnaby, the Royal Navy Director of Naval Construction, her hull was of composite construction; that is, iron keel, frames, stem and stern posts with wooden planking. She was fitted with a 2-cylinder horizontal compound expansion steam engine driving a single screw, which was also built in the Ma ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...

Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Chamfer
A chamfer ( ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces. Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, and to facilitate assembly of many mechanical engineering designs. Terminology In materials and manufacturing, a ''chamfer'' is used to "ease" otherwise sharp edges, both for safety and to prevent damage to the edges; it may also be a primarily decorative feature. In general terms it may be regarded as a type of ''bevel'', and the terms are often used interchangeably. However, in machining, only the term chamfer is used for the specific technique, practice, and result. In carpentry, a lark's tongue is a chamfer which ends short of the end of a piece in a gradual outward curve, leaving the remainder of the edge as a right angle. Chamfers may be formed in either inside or outside adjoining faces of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Paragliding
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness or in a cocoon-like 'pod' suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside. Despite not using an engine, paraglider flights can last many hours and cover many hundreds of kilometres, though flights of one to five hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height, often climbing to altitudes of a few thousand metres. History In 1966, Canadian Domina Jalbert was granted a patent for a ''multi-cell wing type aerial device—''"a wing having a flexible canopy constituting an upper skin and with a plurality of longitudinally extending ribs form ...
