19-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] |

Rack Railway
A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, United Kingdom, where the first commercially successful steam locomotive, '' Salamanca'', ran in 1812. This used a rack and pinion system designed and patented in 1811 by John Blenkinsop. The first mountain cog railway was the Mount Washington Cog Railway in the U.S. state of New Hampshire, which carried its first fare-paying passengers in 1868. The track was comp ...

Rack (web Server Interface)
Rack is a modular interface between web servers and web applications developed in the Ruby programming language. With Rack, application programming interfaces (APIs) for web frameworks and middleware are wrapped into a single method call handling HTTP requests and responses. Rack is used by many Ruby web frameworks and libraries, such as Ruby on Rails and Sinatra. It is available as a Ruby Gem. Many Ruby applications are called "rack-compliant". Rack has inspired similar frameworks in JavaScript (jack.js), Clojure, Perl ( Plack), Common Lisp (Clack), and .NET ( OWIN). Overview The characteristics of a Rack application is that the application object responds to the call method. The call method takes in the environment object as argument and returns the Rack response object. Environment The environment that is taken as argument by the call method refers to an object that has: a) Information on the HTTP Request This includes the information like: * HTTP request method ...

Rack And Pinion
A rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear ...

Racks Railway Station
Racks railway station was a railway station in Dumfries and Galloway, Scotland, south of Dumfries, OS NGR NY 033 743, serving and effectively creating the village of Racks near the Lochar Water, 4 miles ESE of Dumfries; a rural community within the Parish of Torthorwald. History The station, 62.64 miles south of Glasgow Saint Enoch station, opened in July 1848. The station is now closed, although the line running through the station remains open. The station building has been converted into a private dwelling. The difference in height between the main building and platform level was overcome by the use of two fenced diagonal ramps built into the slope with the remainder of the area occupied by a profusion of shrubbery and flower beds. Racks was opened by the Glasgow, Dumfries and Carlisle Railway, which then became part of the Glasgow and South Western Railway; in 1923 it became part of the London Midland and Scottish Railway at the Grouping, passing on to the Scottis ...

Laboratory Drying Rack
Laboratory drying rack is a pegboard for hanging and draining glassware in a laboratory. It is available in different varieties and sizes. It can be used for different materials of glassware in the laboratory room such as funnels, pipettes, mixing balls, slides, bottle stoppers, tubing and so on.Lab Drying Racks. (2016). ''M2 Scientifics.'' Retrieved from: https://www.m2scientifics.com/100-lab-drying-racks In addition to that, the pegs on the drying rack are easily removable and replaceable in order to maintain the cleaning of the lab racks to avoid contamination with other apparatus used on the same rack. Any common laboratory needs to have at least two or three drying racks per lab.Mallapaty G.(2001). Equipment Requirements for a PHC Centre Laboratory. ''The Public Health Care Laboratory.''

Edmund Rack
Edmund Rack (c.1735 – 22 February 1787), born in Norfolk, England, became well known in Bath, Somerset; he was a writer, particularly about agriculture, and founded notable societies. Life Rack was born in Attleborough, Norfolk, about 1735, son of Edmund and Elizabeth Rack. His father was a weaver, and both his parents were Quakers, the mother being a preacher. He was brought up as a Quaker, and apprenticed to a general shopkeeper at Wymondham. At the end of his term he moved to Great Bardfield in Essex, where he became shopman to a Miss Agnes Smith, whom he subsequently married. About 1775 he settled in Bath, Somerset, and, having cultivated a taste for literature, was patronised by Lady Miller of Batheaston, Mrs Macaulay, and Dr Wilson. Before he left Norfolk he had paid great attention to its system of farming, and, with a view to the improvement of that in use throughout the western counties of England, he drew up, in the autumn of 1777, a plan for the formation of a so ...

Bicycle Stand
A bicycle parking rack, usually shortened to bike rack and also called a bicycle stand, is a device to which bicycles can be securely attached for parking purposes. A bike rack may be free standing or it may be securely attached to the ground or some stationary object such as a building. Indoor bike racks are commonly used for private bicycle parking, while outdoor bike racks are often used in commercial areas. General styles of racks include the Inverted U, Serpentine, Bollard, Grid, and Decorative. The most effective and secure bike racks are those that can secure both wheels and the frame of the bicycle, using a bicycle lock. Bike racks can be constructed from a number of different materials. Durability, weather resistance, appearance, and functionality are extremely important factors when choosing the material of the bike rack. Construction materials include stainless steel, steel, recycled plastic, or thermoplastic. Each material has advantages and disadvantages, and each ...

Pallet Racking
Pallet rack is a material handling storage aid system designed to store materials on pallets (or “skids”). Although there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels. Forklift trucks are usually required to place the loaded pallets onto the racks for storage. Since the Second World War, pallet racks have become a ubiquitous element of most modern warehouses, manufacturing facilities, retail centers, and other storage and distribution facilities. All types of pallet racking increase storage density of the stored goods. Costs associated with the racking increases with increasing storage density. Selective pallet racking systems Selective pallet racking is a common pallet racking system in use today. Selective pallet racking systems typically come in one of two configurations: a roll formed, or clip-in configuration, and a structural bolt-together configuration. #Roll formed selecti ...
