Binder Clip
A binder clip (also known as a foldback clip, paper clamp, banker's clip, foldover clip, bobby clip, or clasp) is a simple device for binding sheets of paper together. It leaves the paper intact and can be removed quickly and easily, unlike the staple. It is also sometimes referred to as a handbag clip because of resemblance to a handbag when its clips are folded up. Characteristics and methods of use A binder clip is a strip of spring steel bent into the shape of an isosceles triangle with loops at the apex. Tension along the base of the triangle forces the two sides closed, and the loops prevent the sharp steel edges from cutting into the paper. The loops also serve to hold two pieces of stiff wire, which are used as handles and allow the clip to be opened. The two slots cut in each loop are shaped so that the wire handles can be folded down once the clip has been attached, and the spring force of the wire holds them down on the surface of the paper. This holds the clip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
XB-70
The North American Aviation XB-70 Valkyrie is a retired prototype version of the planned nuclear-armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. Designed in the late 1950s by North American Aviation (NAA) to replace the B-52 Stratofortress and B-58 Hustler, the six-engine, delta-winged Valkyrie could cruise for thousands of miles at Mach 3+ while flying at . At these speeds, it was expected that the B-70 would be practically immune to interceptor aircraft, the only effective weapon against bomber aircraft at the time. The bomber would spend only a brief time over a particular radar station, flying out of its range before the controllers could position their fighters in a suitable location for an interception. Its high speed made the aircraft difficult to see on radar displays and its high-altitude and high-speed capabilities could not be matched by any contemporaneous Soviet interceptor or fighter aircraft.

Stationery
Stationery refers to writing materials, including cut paper, envelopes, continuous form paper, and other office supplies. Stationery usually specifies materials to be written on by hand (e.g., letter paper) or by equipment such as computer printers. History of stationery Originally, the term 'stationery' referred to all products sold by a stationer, whose name indicated that his book shop was on a fixed spot. This was usually somewhere near a university, and permanent, while medieval trading was mainly carried on by itinerant peddlers (including chapmen, who sold books) and others (such as farmers and craftsmen) at markets and fairs. It was a unique term used between the 13th and 15th centuries in the manuscript culture. Stationers' shops were places where books were bound, copied, and published. These shops often loaned books to nearby university students for a fee. The books were loaned out in sections, allowing students to study or copy them, and the only way to get the ...

Fasteners
A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel. Other methods of joining materials, some of which may create permanent joints, include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners. Furniture supplied in flat-pack form often uses cam dowels locke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Treasury Tag
A treasury tag, India tag, or string tag is an item of stationery used to fasten sheets of paper together or to a file folder, folder. It consists of a short length of string, with metal or plastic cross-pieces at each end that are orthogonal to the string. They are threaded through holes in paper or card made with a hole punch or lawyers bodkin or electric drill, and the cross-pieces are sufficiently wide as to not slip back through the holes. The names ''Treasury tag'' and ''India tag'' are first found on record in a list of stationery items published by Her Majesty's Stationery Office, His Majesty's Stationery Office (HMSO) in 1912, and, both being capitalised, probably refer to HM Treasury and the India Office. While the terms are now equivalent, a ''Treasury tag'' was originally a lace with a sharp metal tag at one end, which could be threaded through the holes in a stack of documents or cards and inserted into a corresponding tag at the other end, thus forming a loop and bin ...

Clipboard
A clipboard is a thin, rigid writing board with a clip at the top for holding paper in place. A clipboard is typically used to support paper with one hand while writing on it with the other, especially when other writing surfaces are not available. The earliest forms were patented in 1870–1871 and referred to as board clips. Another early version of the clipboard, known as the "memorandum file", was invented by American inventor George Henry Hohnsbeen in 1921, for which he was granted . Related to the clipboard is the Shannon Arch File, which was developed around 1877. Variations Clipboards can be constructed from a variety of material, including but not limited to, hardboard, aluminum, PVC, polypropylene, High Impact Polystyrene, and Foamex. Clipboards generally come in two different designs—single or folding. Single clipboards are the more traditional type and consist of a single piece of rigid material and some sort of fixing mechanism along the top. Folding clipboar ...

Bulldog Clip
A bulldog clip is a device for temporarily but firmly binding sheets of paper together. It consists of a rectangular sheet of springy steel curved into a cylinder, with two flat steel strips inserted to form combined handles and jaws. The user presses the two handles together, causing the jaws to open against the force of the spring, then inserts a stack of papers and releases the handles. The spring forces the jaws together, gripping the papers firmly. A bulldog clip combined with a suitable piece of board makes a clipboard. History and trademark ''BULLDOG'' is a registered trademark of Brandsley Limited which is licensed to Faire Bros & Co Limited. Its registration as a trademark in the United Kingdom dates back to 1944. Alternative uses Bulldog clips can be used in many domestic, industrial, and arts and crafts applications, including: *The binding of a flip book allowing sheets to be added, removed or replaced. *A cable tidy at a computer station. The clip can be clampe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Historical Society Of Washington, D
History is the systematic study of the past, focusing primarily on the human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives of several sources to develop a ...
