Secret Life Of Machines
''The Secret Life of Machines'' is an educational television series presented by Tim Hunkin and Rex Garrod, in which the two explain the inner workings and history of common household and office machinery. According to Hunkin, the show's creator, the programme was developed from his comic strip ''The Rudiments of Wisdom'', which he researched and drew for the ''Observer'' newspaper over a period of 14 years. Three separate groupings of the broadcast were produced and originally shown between 1988 and 1993 on Channel 4 in the United Kingdom, with the production subsequently broadcast on The Learning Channel and the Discovery Channel in the U.S. Contents Each of the ''Secret Lifes individual series covers a particular set of machines. The first addresses household appliances, while the second includes devices used outside the home, such as the car. The third series examines the contraptions and gadgets used in a modern office. Each episode was given an individual title, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure-sensitive Tape
Pressure-sensitive tape, known also in various countries as PSA tape, adhesive tape, self-stick tape, sticky tape, Sellotape, or just tape, is an adhesive tape that will stick with application of pressure, without the need for a solvent (such as water) or heat for activation. PSA tape consists of three components: *the tape itself, which often is cellophane, cellulose acetate, or polyvinyl chloride. Other materials include paper, plastic film, cloth, or metal foil.coated onto a backing material such as paper, plastic film, cloth, or metal foil. *a pressure-sensitive adhesive. *release liner, which keeps the tape from sticking to itself. Some have layers of adhesives, primers, release agents, filaments, printing, etc. made for specific functions. It will stick without the need for a solvent such as water or heat for activation. By contrast, "gummed" or "water activated" adhesive tapes require warm water for activation and "heat activated" tapes require heat. Single-sided ...

Pyrotechnics
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words ''pyr'' ("fire") and ''tekhnikos'' ("made by art"). People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximat ...

Installation Art
Installation art is an artistic genre of three-dimensional works that are often site-specific and designed to transform the perception of a space. Generally, the term is applied to interior spaces, whereas exterior interventions are often called public art, land art or art intervention; however, the boundaries between these terms overlap. History Installation art can be either temporary or permanent. Installation artworks have been constructed in exhibition spaces such as museums and galleries, as well as public and private spaces. The genre incorporates a broad range of everyday and natural materials, which are often chosen for their " evocative" qualities, as well as new media such as video, sound, performance, immersive virtual reality and the internet. Many installations are site-specific in that they are designed to exist only in the space for which they were created, appealing to qualities evident in a three-dimensional immersive medium. Artistic collectives such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilogue
An epilogue or epilog (from Greek ἐπίλογος ''epílogos'', "conclusion" from ἐπί ''epi'', "in addition" and λόγος ''logos'', "word") is a piece of writing at the end of a work of literature, usually used to bring closure to the work. It is presented from the perspective of within the story. When the author steps in and speaks directly to the reader, that is more properly considered an afterword. The opposite is a prologue—a piece of writing at the ''beginning'' of a work of literature or drama, usually used to open the story and capture interest. Some genres, for example television programs and video games, call the epilogue an "outro" patterned on the use of "intro" for "introduction". Epilogues are usually set in the future, after the main story is completed. Within some genres it can be used to hint at the next installment in a series of work. It is also used to satisfy the reader's curiosity and to cover any loose ends of the story. History of the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator
An elevator or lift is a cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or decks of a building, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are often a legal requirement in new multistory buildings, espec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron(III) Oxide
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide. Structure Fe2O3 can be obtained in various polymorphs. In the main one, α, iron adopts octahedral coordination geometry. That is, each Fe center is bound to six oxygen ligands. In the γ polymorph, some of the Fe sit on tetrahedral sites, with four oxygen ligands. Alpha phase α-Fe2O3 has the rhombohedral, corundum (α-Al2O3) structure and ...

Video Tape Recorder
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. Beginning in 1963, videotape machines made instant replay during televised sporting events possible. Improved formats, in which the tape was contained inside a videocassette, were introduced around 1969; the machines which play them are called videocassette recorders. An agreement by Japanese manufacturers on a common standard recording format, which allowed cassettes recorded on one manufacturer's machine to play on another's, made a consumer market possible; and the first consumer videocassette recorder, which used the U-matic format, was introduced by Sony in 1971.

Automobile
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Appliances
A home appliance, also referred to as a domestic appliance, an electric appliance or a household appliance, is a machine which assists in household functions such as cooking, cleaning and food preservation. Appliances are divided into three types: small appliances, major appliances (also known as white goods) and consumer electronics (brown goods). Definition Given a broad usage, the domestic application attached to home appliance is tied to the definition of appliance as "an instrument or device designed for a particular use or function". More specifically, Collins English Dictionary defines "home appliance" as: "devices or machines, usually electrical, that are in your home and which you use to do jobs such as cleaning or cooking". The broad usage, afforded to the definition allows for nearly any device intended for domestic use to be a home appliance, including consumer electronics as well as stoves, refrigerators, toasters and air conditioners.
