International Standard Payload Rack
The International Standard Payload Rack (ISPR) is a steel framework container that is designed and been adopted by the International Space Station (ISS) program to support efficient integration and interchangeability of space payload hardware, such as machines and experiments. A typical rack contains 37 ISPR slots for science payloads, which are interchangeable to accommodate different components or payloads. Capabilities Each ISPR provides 1.571 m3 (55.5 ft3) of internal volume being about 2 m (79.3 in) high, 1.05 m (41.3 in) wide, and 85.9 cm (33.8 in) deep. The rack weighs 104 kg (230 lb) and can accommodate an additional 700 kg (1540 lb) of payload equipment. The rack has internal mounting provisions to allow attachment of secondary structure. The ISPRs will be outfitted with a thin center post to accommodate sub-rack-sized payloads, such as the 483 mm ( 19-inch rack) Spacelab Standard Interface Rack (SIR) Dr ...

Each piece of equipment has a front panel that is 19 inches (48.3 cm) wide. The 19-inch dimension includes the edges, or "ears", that protrude on each side, which allow the amplifier or other electronic equipment to be fastened to the rack frame with screws.

Newspaper Vending Machine
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th cen ...

Rack Unit
A rack unit (abbreviated U or RU) is a unit of measure defined as . It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. Definition The rack unit size is based on a standard rack specification as defined in EIA-310. The Eurocard specifies a standard rack unit as the unit of height; it also defines a similar unit, horizontal pitch (HP), used to measure the width of rack-mounted equipment. The standard was adopted worldwide as ''IEC 60297 Mechanical structures for electronic equipment – Dimensions of mechanical structures of the series'', and defines the sizes for rack, subrack (a shelf-like chassis in which cards can be inserted), and the pitch of printed circuit boards/ca ...

23-inch Rack
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, 45U racks are also common. The term ''relay rack'' appeared first in the world of telephony. By 1911, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Rack
Open Rack is an Open Compute Project standard for a new rack and power delivery architecture and an efficient, scalable alternative to thEIA-310 rack It differs from the traditional EIA-310 19" rack in that it was designed specifically for large scale cloud deployments. There are four key features that make this rack design more efficient to deploy, support, and operate. The power to all of the compute, storage, or network devices is supplied by a pair of bus bars located in the rear of the rack. The bus bars are supplied with 48V DC by a shelf of power supplies A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a res ... which provides efficient conversion from the local (usually 3-phase) AC mains supply. The IT equipment that fits into Open Rack is 21" or 538mm wide. This is a 15% increase ...

Tzompantli
A () or skull rack was a type of wooden rack or palisade documented in several Mesoamerican civilizations, which was used for the public display of human skulls, typically those of war captives or other sacrificial victims. It is a scaffold-like construction of poles on which heads and skulls were placed after holes had been made in them. Many have been documented throughout Mesoamerica, and range from the Epiclassic () through early Post-Classic ().Mendoza (2007) pg 397 In 2017 archeologists announced the discovery of the Hueyi Tzompantli, with more than 650 skulls, in the archeological zone of the Templo Mayor in Mexico City. Etymology The name comes from the Classical Nahuatl language of the Aztecs but is also commonly applied to similar structures depicted in other civilizations. Its precise etymology is uncertain although its general interpretation is 'skull rack', 'wall of skulls', or 'skull banner'. It is most likely a compound of the Nahuatl words ('skull'; from or ...

Pipe Rack
Structural steel pipe racks typically support pipes, power cables and instrument cable trays in petrochemical, chemical and power plants. Occasionally, pipe racks may also support mechanical equipment, vessels and valve access platforms. Main pipe racks generally transfer material between equipment and storage or utility areas. Storage racks found in warehouses are not pipe racks, even if they store lengths of pipe.Drake, Richard M., P.E., S.E., SECB and Walter, Robert J., P.E., S.E. A pipe rack is the main artery of a process unit. Pipe racks carry process and utility piping and may also include instrument and cable trays as well as equipment mounted over all of these. Pipe racks consist of a series of transverse beams that run along the length of the pipe system, spaced at uniform intervals typically around 20 ft. To allow maintenance access under the pipe rack, the transverse beams are typically moment frames. Transverse beams are typically connected with longitudinal ...

Spinner Rack
A spinner rack is a rotating merchandise display, usually placed on a retailer's floor or counter. Often used to display magazines, paperbacks, greeting cards, postcards, hats, or seeds, the spinner rack is closely associated with the comic book industry. A typical spinner rack is composed of a metal central spine with wire pockets, baskets, or pegs. A floor unit may have between four and twelve tiers (usually with four pockets on each tier) that may or may not rotate independently. Additional features may include a signholder that sits on top of the unit. (A typical comics spinner rack would have 44 pockets, with each pocket holding around five comics.) Author George R. R. Martin, in writing about the spinner racks he knew as a child, notes that they offered a hodge-podge of titles (in his case paperbacks) regardless of genre, and thus exposed readers to a wide variety of writing, as opposed to the modern bookstore, where books are generally categorized by topic.Martin, George R. R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoe Rack
A shoe rack is a furniture which is often found by the door mat in the entryway of houses, and serves a function to keep shoes organized. Often it is placed near a hat shelf, a hatstand, wardrobe rail, or hook rack where clothes for outdoor use can be hung. Some shoe racks also serve as a bench where persons may sit while taking on their shoes. A well known designer of shoe racks was Gunnar Bolin from Sweden. IKEA has sold shoe racks since at least 1950.
