Caulking Gun
Caulk or, less frequently, caulking is a material used to seal joints or seams against leakage in various structures and piping. The oldest form of caulk consisted of fibrous materials driven into the wedge-shaped seams between boards on wooden boats or ships. Cast iron sewerage pipe were formerly caulked in a similar way. Riveted seams in ships and boilers were formerly sealed by hammering the metal. Modern caulking compounds are flexible sealing compounds used to close up gaps in buildings and other structures against water, air, dust, insects, or as a component in firestopping. In the tunnelling industry, caulking is the sealing of joints in segmental precast concrete tunnels, commonly by using concrete. Historical uses Wooden shipbuilding Traditional caulking (also spelled calking) on wooden vessels uses fibers of cotton and oakum ( hemp) soaked in pine tar. These fibers are driven into the wedge-shaped seam between planks, with a caulking mallet and a broad chisel- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and die ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrack
A carrack (; ; ; ) is a three- or four- masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe, most notably in Portugal. Evolved from the single-masted cog, the carrack was first used for European trade from the Mediterranean to the Baltic and quickly found use with the newly found wealth of the trade between Europe and Africa and then the trans-Atlantic trade with the Americas. In their most advanced forms, they were used by the Portuguese for trade between Europe and Asia starting in the late 15th century, before eventually being superseded in the 17th century by the galleon, introduced in the 16th century. In its most developed form, the carrack was a carvel-built ocean-going ship: large enough to be stable in heavy seas, and capacious enough to carry a large cargo and the provisions needed for very long voyages. The later carracks were square-rigged on the foremast and mainmast and lateen- rigged on the mizzenmast. They had a high roun ...

Severn Trow
A trow was a type of cargo boat found in the past on the rivers Severn and Wye in Great Britain and used to transport goods. Features The mast could be taken down so that the trow could go under bridges, such as the bridge at Worcester and the many bridges up and downstream. The mast was stepped in a three sided frame open at the rear but closed with an iron pin or rope lashing. From the top of the mast a forestay ran down to the bow winch. To lower the mast the pin was removed and the winch slackened off to let the mast fall towards the stern. The reverse operation pulled the mast up. Despite their flat-bottomed hull form which made volume available for their load and permitted drying out on muddy banks in the tidal area where they operated, Trows were seaworthy. For example, with an added keel the Droitwich Trow ''Hastings'' is recorded as taking 90 tons of salt from Droitwich to France across the English Channel. The flat-bottomed trows sailed on the sea by hauling a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ezekiel
Ezekiel (; he, יְחֶזְקֵאל ''Yəḥezqēʾl'' ; in the Septuagint written in grc-koi, Ἰεζεκιήλ ) is the central protagonist of the Book of Ezekiel in the Hebrew Bible. In Judaism, Christianity, and Islam, Ezekiel is acknowledged as a Hebrew prophet. In Judaism and Christianity, he is also viewed as the 6th-century BCE author of the Book of Ezekiel, which reveals prophecies regarding the destruction of Jerusalem, and the restoration to the land of Israel. The name Ezekiel means "God is strong" or "God strengthens". In the Bible The author of the Book of Ezekiel presents himself as Ezekiel, the son of Buzi, born into a priestly (kohen) lineage. Apart from identifying himself, the author gives a date for the first divine encounter which he presents: "in the thirtieth year". Ezekiel describes his calling to be a prophet by going into great detail about his encounter with God and four "living creatures" with four wheels that stayed beside the creatures. Liv ...

Biblical Prophet
In religion, a prophet or prophetess is an individual who is regarded as being in contact with a divine being and is said to speak on behalf of that being, serving as an intermediary with humanity by delivering messages or teachings from the supernatural source to other people. The message that the prophet conveys is called a prophecy. Claims of prophethood have existed in many cultures and religions throughout history, including Judaism, Christianity, Islam, ancient Greek religion, Zoroastrianism, Manichaeism, Hinduism , and many others. Etymology The English word ''prophet'' is the transliteration of a compound Greek word derived from ''pro'' (before/toward) and ''phesein'' (to tell); thus, a προφήτης (''prophḗtēs'') is someone who conveys messages from the divine to humans, including occasionally foretelling future events. In a different interpretation, it means advocate or speaker. In Hebrew, the word נָבִיא (''nāvî''), "spokesperson", traditionally ...

Hebrew Bible
The Hebrew Bible or Tanakh (;"Tanach" ''Random House Webster's Unabridged Dictionary''. Hebrew: ''Tānāḵh''), also known in Hebrew as Miqra (; Hebrew: ''Mīqrā''), is the Biblical canon, canonical collection of Hebrew language, Hebrew scriptures, including the Torah, the Nevi'im, and the Ketuvim. Different branches of Judaism and Samaritanism have maintained different versions of the canon, including the 3rd-century Septuagint text used by Second-Temple Judaism, the Syriac language Peshitta, the Samaritan Torah, the Dead Sea Scrolls, and most recently the 10th century medieval Masoretic Text, Masoretic text created by the Masoretes currently used in modern Rabbinic Judaism. The terms "Hebrew Bible" or "Hebrew Canon" are frequently confused with the Masoretic text, however, this is a medieval version and one of several ...

Calefaction
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Pitch (resin)
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, or plants. Various forms of pitch may also be called tar, bitumen, or asphalt. Pitch produced from plants is also known as resin. Some products made from plant resin are also known as rosin. Uses Pitch was traditionally used to help caulk the seams of wooden sailing vessels (see shipbuilding), and to coat earthenware vessels for the preservation of wine. Pitch may also be used to waterproof wooden containers and in the making of torches. Petroleum-derived pitch is black in colour, hence the adjectival phrase, "pitch-black". The viscoelastic properties of pitch make it well suited for the polishing of high-quality optical lenses and mirrors. In use, the pitch is formed into a lap or polishing surface, which is charged with iron oxide ( Jewelers' rouge) or cerium oxide. The surface to be polished is pressed into the pitch, then rubbed against the surface so formed. The ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Putty
Putty is a material with high plasticity, similar in texture to clay or dough, typically used in domestic construction and repair as a sealant or filler. Although some types of putty (typically those using linseed oil) slowly polymerise and become stiff, many putties can be reworked indefinitely, in contrast to other types of filler which typically set solid relatively rapidly. Chemical composition Putty, or lime putty, is made from a mixture of calcium oxide (CaO) and water (H2O) in proportions of 38% and 62% by weight respectively, as result, the solution forms hydrated lime (Ca(OH)2) which takes up about a half of the weight. The other putty mixture may be a calcium carbonate (CaCO3, 750-850 parts) based with a admixtures of CaO (ash calcium, 120-180 parts), white cement (40-60 parts), and talc powders in much lower concentrations (fractions). Applications Use in construction Putty has been used extensively in glazing for fixing and sealing panes of glass into woo ...

Chisel
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chiselling use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material. A gouge (one type of chisel) serves to carve small pieces from the material, particularly in woodworking, woodturning and sculpture. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section. Etymology ''Chisel'' comes from the Old French ''cisel'', modern ''ciseau'', Late Latin ''cisel ...
