The Flask, Highgate
The Flask is a Grade II listed public house at 74–76 Highgate West Hill, Highgate, London. According to the 1936 ''Survey of London'', a pub known as The Flask has stood on this spot since "at least as early as 1663". The present buildings probably date from the early 18th century, and were partially rebuilt in about 1767 by William Carpenter. A Manorial court met there in the eighteenth century. The Flask is currently owned and operated by the London-based Fuller's. History The pub is believed to have been named after the flasks of Hampstead mineral water that could be purchased here when Hampstead was popular for its wells in the 18th century, and The Flask, Flask Walk, Hampstead, is another pub nearby. Like all good pubs, The Flask has its own legends which may or may not be true. It is said that the highwayman Dick Turpin hid from the law in the stables there, that the artist William Hogarth drank at the bar and even that Karl Marx was a customer. For good measure, the pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hip Flask
A hip flask is a thin flask for holding liquor. Description Hip flasks were traditionally made of pewter, silver, or even glass, though most modern flasks are made from stainless steel. Some modern flasks are made of plastic so as to avoid detection by metal detectors. Hip flasks can vary in shape, although they are usually contoured to match the curve of the wearer's hip or thigh for comfort and discretion in a design also known as a kidney flask. Some flasks have a "captive top", which is a small arm that attaches the top to the flask in order to stop it from getting lost when it is taken off. A hip flask is most commonly purchased empty and then filled by the owner. However, the term "flask" also applies to smallest bottle sizes of alcohol in commercial markets. Some flasks come with small cups to make sharing easier, although generally liquid is consumed directly from the flask. History The hip flask began to appear in the form it is recognized today in the 18th centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laboratory Flask
Laboratory flasks are vessels or containers that fall into the category of laboratory equipment known as glassware. In laboratory and other scientific settings, they are usually referred to simply as flasks. Flasks come in a number of shapes and a wide range of sizes, but a common distinguishing aspect in their shapes is a wider vessel "body" and one (or sometimes more) narrower tubular sections at the top called necks which have an opening at the top. Laboratory flask sizes are specified by the volume they can hold, typically in metric units such as milliliters (mL or ml) or liters (L or l). Laboratory flasks have traditionally been made of glass, but can also be made of plastic. At the opening(s) at top of the neck of some glass flasks such as round-bottom flasks, retorts, or sometimes volumetric flasks, there are outer (or female) tapered (conical) ground glass joints. Some flasks, especially volumetric flasks, come with a laboratory rubber stopper, bung, or cap for capping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erlenmeyer Flask
An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860. Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck. They may be graduated, and often spots of ground glass or enamel are used where they can be labeled with a pencil. It differs from the beaker in its tapered body and narrow neck. Depending on the application, they may be constructed from glass or plastic, in a wide range of volumes. The mouth of the Erlenmeyer flask may have a beaded lip that can be stopped or covered. Alternatively, the neck may be fitted with ground glass or other connector for use with more specialized stoppers or attachment to other apparatus. A Büchner flask is a common design modification for filtration under vacuum. Uses In chemistr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum Flask
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection. When used to hold cold liquids, this also virtually eliminates condensation on the outside of the flask. Vacuum flasks are used domestically to keep beverages hot or cold for extended periods of time, and for keeping cooked food hot. They are also used for thermal cooking. Vacuum flasks are also used for many purposes in industry. History The vacuum flask was designed and invented by Scottish scientist Sir James Dewar in 1892 as a result of his research in the field of cryogenics ...

Flask (metal Casting)
A flask is a type of tooling used to contain a mold in metal casting. A flask has only sides, and no top or bottom, and forms a frame around the mold, which is typically made of molding sand. The shape of a flask may be square, rectangular, round or any convenient shape. A flask can have any size so long as it is larger than the pattern being used to make the sand mold. Flasks are commonly made of steel, aluminum or even wood. A simple flask has two parts: the cope and the drag. More elaborate flasks may have three or even four parts. Flask design Flasks are often designed with bars that extend to span two opposite sides. The bars act as reinforcement to the molding sand, which is relatively weak in tensile strength. The bars help support the sand through the molding and pouring operation. Flasks are designed with an alignment or registration feature, so that the two flasks can be aligned to one another to ensure a casting can be more dimensionally accurate and also in smal ...

Flask (web Framework)
Flask is a micro web framework written in Python. It is classified as a microframework because it does not require particular tools or libraries. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions. However, Flask supports extensions that can add application features as if they were implemented in Flask itself. Extensions exist for object-relational mappers, form validation, upload handling, various open authentication technologies and several common framework related tools. Applications that use the Flask framework include Pinterest and LinkedIn. History Flask was created by Armin Ronacher of Pocoo, an international group of Python enthusiasts formed in 2004. According to Ronacher, the idea was originally an April Fool's joke that was popular enough to make into a serious application. The name is a play on the earlier Bottle framework. When Ronacher and Georg Brandl created a bullet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powder Flask
A powder flask is a small container for gunpowder, which was an essential part of shooting equipment with muzzle-loading guns, before pre-made paper cartridges became standard in the 19th century. They range from very elaborately decorated works of art to early forms of consumer packaging, and are widely collected. Many were standardized military issue, but the most decorative were generally used for sporting shooting. Although the term powder horn is sometimes used for any kind of powder flask, it is strictly a sub-category of flask made from a hollowed bovid horn. Powder flasks were made in a great variety of materials and shapes, though ferrous metals that were prone to give off sparks when hit were usually avoided. Stag antler, which could be carved or engraved, was an especially common material, but wood and copper were common, and in India, ivory. Many types of early guns required two different forms of gunpowder (such as a flintlock with finer priming powder for the pan, a ...

The Flask, Hampstead
The Flask is a Grade II listed public house at 14 Flask Walk, Hampstead, London, on the site from where the trade in Hampstead mineral water was run, and which is mentioned in the eighteenth century novel ''Clarissa''. It has been owned by Young's Brewery since 1904. Name It was originally known as the Lower Flask, to distinguish it from the Upper Flask, a tavern near the top of Hampstead hill which was patronised by Whig grandees and writers but which closed in the 1750s. The clientele of the Lower Flask was considered inferior; and it appears in Samuel Richardson's novel ''Clarissa'' as the place of a drunk, "I have got the fellow down! — I have got old Grimes — hah, hah, hah, hah! — He is at the Lower Flask — almost in the condition of David's sow...". It was also known as the Thatched House until the premises were rebuilt by Cumming and Nixon in 1874, when it became known just as The Flask.
