Racking Focus
A focus puller or first assistant camera (1st AC) is a member of a film crew's camera department whose primary responsibility is to maintain the camera lens's optical focus on whatever subject or action is being filmed. "Pulling focus" refers to the act of changing the camera lens's focus distance to a moving subject's distance from the focal plane, or the changing distance between a stationary object and a moving camera. For example, if an actor moves from 8 m to 3 m away from the focal plane within a shot, the focus puller will change the distance setting on the lens in precise relation to the changing position of the actor. Additionally, the focus puller may shift focus from one subject to another within the frame, as dictated by the requirements of the shot. This process is called "rack focusing". Focus pulling There is often very little room for error, depending on the parameters of a given shot. The role of a focus puller is extremely important to a film productio ...

Racking
Racking, often referred to as Soutirage or Soutirage traditionnel (meaning racking in French), also filtering or fining, is the process of moving wine or beer from one container to another using gravity rather than a pump, which can be disruptive to the beverage. The process is also known as ''Abstich'' in German and ''travaso'' in Italian. ''Alexis Lichine's Encyclopedia of Wines and Spirits'' defines racking as "siphoning wine or beer off the lees (in the case of wine) or trub (in the case of beer), into a new, clean barrel or other vessel". Racking allows clarification and aids in stabilization. Wine that is allowed to age on the lees often develops "off-tastes". A racking hose or tube is used and can be attached to a racking cane to make the task easier. The racking process is repeated several times during the aging of wine. Process Racking or soutirage is a traditional method in wine production of moving wine from one barrel to another using gravity rather than a pump. ...

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 *The ...

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 Scottish Re ...

Ambling Gait
An ambling gait or amble is any of several four-beat intermediate horse gaits, all of which are faster than a walk but usually slower than a canter and always slower than a gallop. Horses that amble are sometimes referred to as "gaited", particularly in the United States. Ambling gaits are smoother for a rider than either the two-beat trot or pace and most can be sustained for relatively long periods, making them particularly desirable for trail riding and other tasks where a rider must spend long periods in the saddle. Historically, horses able to amble were highly desired for riding long distances on poor roads. Once roads improved and carriage travel became popular, their use declined in Europe but continued in popularity in the Americas, particularly in areas where plantation agriculture was practiced and the inspection of fields and crops necessitated long daily rides. The ability to perform an ambling gait is usually an inherited trait. In 2012, a DNA study found that ... [...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 comple ...

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 ...
