Church Key (instrumental)
A church key or churchkey is a North American term for various kinds of bottle openers and can openers. Etymology The term in the beverage-opening sense is apparently not an old one; Merriam-Webster finds written attestation only since the 1950s. Several etymological themes exist. The main one is that the ends of some bottle openers resemble the heads of large keys such as have traditionally been used to lock and unlock church doors. History A church key initially referred to a simple hand-operated device for prying the cap off a glass bottle. Called a "crown cork" and later a “bottle cap”, this kind of closure was invented in 1892, with a patent awarded to William Painter. Two years later, Painter also received a patent on an opener, then called a "bottle cap lifter", to be used with the caps. While there is no evidence that the opener was called a church key at that time, the shape and design of some of these openers did resemble a large simple key. In 1935 ...

Bottle Opener
A bottle opener is a device that enables the removal of metal bottle caps from glass bottles. More generally, it might be thought to include corkscrews used to remove cork or plastic stoppers from wine bottles. A metal bottle cap is affixed to the rim of the neck of a bottle by being pleated or ruffled around the rim. A bottle opener is a specialized lever inserted beneath the pleated metalwork, which uses a point on the bottle cap as a fulcrum on which to pivot. History Invention of the bottle opener is credited to William Painter, who receive a patent on the crown cork bottle cap in 1892, and a patent on the first bottle opener (then called a "bottle cap lifter") in 1894. Varieties There are several distinct designs of such bottle openers. Wall mounted openers are typically found behind bars in pubs, whilst hand-tool bottle openers tend to be found and used in domestic environments. The functional elements of bottle openers (a tooth or lip to catch the underside of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Can Opener
A can opener (North American and Australian English) or tin opener (British English) is a mechanical device used to open metal tin cans. Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced. A can opener using the now familiar rotating cutting wheel that runs round the can's rim to cut open the lid was invented in 1870, but the first such design was considered very difficult to operate for the ordinary consumer. A more successful design came out in 1925 when a second, opposing wheel was added, with a serrated surface to grip the rim of the can and keep the lid in contact with the cutting wheel. This easy-to-use design has become one of the most popular can opener models. Around the time of World War II, several can openers were deve ...

Ancient Warded Lock Key Transparent
Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BCAD 500, ending with the expansion of Islam in late antiquity. The three-age system periodises ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history generally considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others. During the time period of ancient history, the world population was exponentially increasing due to the Neolithic Revolution, which was in full prog ...

Clé Ouvre-bouteille
A clef (from French: 'key') is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical staff. Placing a clef on a staff assigns a particular pitch to one of the five lines or four spaces, which defines the pitches on the remaining lines and spaces. The three clef symbols used in modern music notation are the G-clef, F-clef, and C-clef. Placing these clefs on a line fixes a reference note to that line—an F-clef fixes the F below middle C, a C-clef fixes middle C, and a G-clef fixes the G above middle C. In modern music notation, the G-clef is most frequently seen as treble clef (placing G4 on the second line of the staff), and the F-clef as bass clef (placing F3 on the fourth line). The C-clef is mostly encountered as alto clef (placing middle C on the third line) or tenor clef (middle C on the fourth line). A clef may be placed on a space instead of a line, but this is rare. The use of different clefs makes it possible to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Word Sense
In linguistics, a word sense is one of the meanings of a word. For example, a dictionary may have over 50 different senses of the word "play", each of these having a different meaning based on the context of the word's usage in a sentence, as follows: In each sentence different collocates of "play" signal its different meanings. People and computers, as they read words, must use a process called word-sense disambiguationR. Navigli''Word Sense Disambiguation: A Survey'' ACM Computing Surveys, 41(2), 2009, pp. 1-69. to reconstruct the likely intended meaning of a word. This process uses context to narrow the possible senses down to the probable ones. The context includes such things as the ideas conveyed by adjacent words and nearby phrases, the known or probable purpose and register of the conversation or document, and the orientation (time and place) implied or expressed. The disambiguation is thus context-sensitive. Advanced semantic analysis has resulted in a sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etymology
Etymology ( ) is the study of the origin and evolution of words—including their constituent units of sound and meaning—across time. In the 21st century a subfield within linguistics, etymology has become a more rigorously scientific study. Most directly tied to historical linguistics, philology, and semiotics, it additionally draws upon comparative semantics, morphology, pragmatics, and phonetics in order to attempt a comprehensive and chronological catalogue of all meanings and changes that a word (and its related parts) carries throughout its history. The origin of any particular word is also known as its ''etymology''. For languages with a long written history, etymologists make use of texts, particularly texts about the language itself, to gather knowledge about how words were used during earlier periods, how they developed in meaning and form, or when and how they entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Cork
The crown cork (also known as a crown seal, crown cap or just a cap), the first form of bottle cap, was invented by William Painter in 1892 in Baltimore. The company making it was originally called the Bottle Seal Company, but it changed its name with the almost immediate success of the crown cork to the ''Crown Cork and Seal Company''. It still informally goes by that name, but is officially Crown Holdings. Overview A Dutch patent application from 1892 This style of closure is still in widespread use. Prior to the invention of the external crown cork bottle stopper, soda bottles had ordinary internal cork bottle stoppers and often had rounded bottoms so they could not be stored standing upright. Corks have a tendency to dry out and shrink, allowing the gas pressure in the bottle to cause the cork to "pop", so bottles were stored on their side to prevent the corks from drying out. After the invention of the crown cork bottle stopper, this problem was eliminated, and soda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Painter (inventor)
William Painter (November 20, 1838 – July 15, 1906) was an American mechanical engineer, inventor and the founder of Crown Holdings, Inc., a Fortune 500 company. He most notably invented the crown cork bottle cap and bottle opener. Early life and career Painter was born in 1838 in Triadelphia, then a mill town in Montgomery County, Maryland to Dr. Edward Painter and Louisa Gilpin Painter. He moved to Baltimore, Maryland in 1865 to begin a career as a foreman at the Murrill & Keizer's machine shop. He worked with manufacturers to develop a universal neck for all glass bottles and started the Crown Cork & Seal Company of Baltimore in 1892 to manufacture caps that could be used to seal the universal necks.he died in July 1906 at 67 Patents Painter patented 85 inventions, including the common bottle cap, the bottle opener, a machine for crowning bottles, a paper-folding machine, a safety ejection seat for passenger trains, and also a machine for detecting counterfeit curre ...

Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a Private university, private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of modern technology and science. In response to the increasing Technological and industrial history of the United States, industrialization of the United States, William Barton Rogers organized a school in Boston to create "useful knowledge." Initially funded by a land-grant universities, federal land grant, the institute adopted a Polytechnic, polytechnic model that stressed laboratory instruction in applied science and engineering. MIT moved from Boston to Cambridge in 1916 and grew rapidly through collaboration with private industry, military branches, and new federal basic research agencies, the formation of which was influenced by MIT faculty like Vannevar Bush. In the late twentieth century, MIT became a leading center for research in compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Key (lock)
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the '' bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key ...
