Elevator

The first electric elevator was built by Werner von Siemens in 1880 in Germany. The inventor Anton Freissler developed the ideas of von Siemens and built up a successful enterprise in Austria-Hungary. The safety and speed of electric elevators were significantly enhanced by Frank Sprague who added floor control, automatic elevators, acceleration control of cars, and safeties. His elevator ran faster and with larger loads than hydraulic or steam elevators, and 584 electric elevators were installed before Sprague sold his company to the Otis Elevator Company in 1895. Sprague also developed the idea and technology for multiple elevators in a single shaft.

Question: The first electric elevator, built in 1880, was in what Country?
Answer: Germany
Elevator

Sometimes passenger elevators are used as a city transport along with funiculars. For example, there is a 3-station underground public elevator in Yalta, Ukraine, which takes passengers from the top of a hill above the Black Sea on which hotels are perched, to a tunnel located on the beach below. At Casco Viejo station in the Bilbao Metro, the elevator that provides access to the station from a hilltop neighborhood doubles as city transportation: the station's ticket barriers are set up in such a way that passengers can pay to reach the elevator from the entrance in the lower city, or vice versa. See also the Elevators for urban transport section.

Question: Passenger elevators, used in city transport share similarities to what other ascending and descending vehicles counterbalancing each other?    
Answer: funiculars

Question: What type of public elevator in Yalta, Ukraine, transport passengers from a hill above the Black Sea to a tunnel down on the beach?
Answer: underground public elevator

Question: The elevator located at the Casco Viejo station in the Bilbao Metro is also used for what?

Steven_Spielberg

In terms of casting and production itself, Spielberg has a known penchant for working with actors and production members from his previous films. For instance, he has cast Richard Dreyfuss in several films: Jaws, Close Encounters of the Third Kind, and Always. Aside from his role as Indiana Jones, Spielberg also cast Harrison Ford as a headteacher in E.T. the Extra-Terrestrial (though the scene was ultimately cut). Although Spielberg directed veteran voice actor Frank Welker only once (in Raiders of the Lost Ark, for which he voiced many of the animals), Welker has lent his voice in a number of productions Spielberg has executive produced from Gremlins to its sequel Gremlins 2: The New Batch, as well as The Land Before Time, Who Framed Roger Rabbit, and television shows such as Tiny Toons, Animaniacs, and SeaQuest DSV. Spielberg has used Tom Hanks on several occasions and has cast him in Saving Private Ryan, Catch Me If You Can, The Terminal, and Bridge of Spies. Spielberg has collaborated with Tom Cruise twice on Minority Report and War of the Worlds, and cast Shia LaBeouf in five films: Transformers, Eagle Eye, Indiana Jones and the Kingdom of the Crystal Skull, Transformers: Revenge of the Fallen, and Transformers: Dark of the Moon.

Question: Who was Ford going to play in E.T., until the scene was removed?
Answer: a headteacher

There are several technologies aimed to provide better experience to passengers suffering from claustrophobia, anthropophobia or social anxiety. Israeli startup DigiGage uses motion sensors to scroll the pre-rendered images, building and floor-specific content on a screen embedded into the wall as the cab moves up and down. British company LiftEye provides a virtual window technology to turn common elevator into panoramic. It creates 3d video panorama using live feed from cameras placed vertically along the facade and synchronizes it with cab movement. The video is projected on a wall-sized screens making it look like the walls are made of glass.

Question: What Israeli company uses motion sensors to display information on a screen embedded in the wall of the cabs?
Answer: DigiGage

Elevators necessitated new social protocols. When Nicholas II of Russia visited the Hotel Adlon in Berlin, his courtiers panicked about who would enter the elevator first, and who would press the buttons. In Lifted: A Cultural History of the Elevator, author Andreas Bernard documents other social impacts caused by the modern elevator, including thriller movies about stuck elevators, casual encounters and sexual tension on elevators, the reduction of personal space, and concerns about personal hygiene.

A famous example of Spielberg working with the same professionals is his long-time collaboration with John Williams and the use of his musical scores in all of his films since The Sugarland Express (except Bridge of Spies, The Color Purple and Twilight Zone: The Movie). One of Spielberg's trademarks is his use of music by Williams to add to the visual impact of his scenes and to try and create a lasting picture and sound of the film in the memories of the film audience. These visual scenes often uses images of the sun (e.g. Empire of the Sun, Saving Private Ryan, the final scene of Jurassic Park, and the end credits of Indiana Jones and the Last Crusade (where they ride into the sunset)), of which the last two feature a Williams score at that end scene. Spielberg is a contemporary of filmmakers George Lucas, Francis Ford Coppola, Martin Scorsese, John Milius, and Brian De Palma, collectively known as the "Movie Brats". Aside from his principal role as a director, Spielberg has acted as a producer for a considerable number of films, including early hits for Joe Dante and Robert Zemeckis. Spielberg has often never worked with the same screenwriter in his films, beside Tony Kushner and David Koepp, who have written a few of his films more than once.

Question: What are the only Spielberg films since Sugarland Express to not have music by John Williams?
Answer: Bridge of Spies, The Color Purple and Twilight Zone: The Movie
Elevator

Past problems with hydraulic elevators include underground electrolytic destruction of the cylinder and bulkhead, pipe failures, and control failures. Single bulkhead cylinders, typically built prior to a 1972 ASME A17.1 Elevator Safety Code change requiring a second dished bulkhead, were subject to possible catastrophic failure. The code previously permitted only single-bottom hydraulic cylinders. In the event of a cylinder breach, the fluid loss results in uncontrolled down movement of the elevator. This creates two significant hazards: being subject to an impact at the bottom when the elevator stops suddenly and being in the entrance for a potential shear if the rider is partly in the elevator. Because it is impossible to verify the system at all times, the code requires periodic testing of the pressure capability. Another solution to protect against a cylinder blowout is to install a plunger gripping device. One commercially available is known by the marketing name "LifeJacket". This is a device which, in the event of an uncontrolled downward acceleration, nondestructively grips the plunger and stops the car. A device known as an overspeed or rupture valve is attached to the hydraulic inlet/outlet of the cylinder and is adjusted for a maximum flow rate. If a pipe or hose were to break (rupture), the flow rate of the rupture valve will surpass a set limit and mechanically stop the outlet flow of hydraulic fluid, thus stopping the plunger and the car in the down direction.

Question: Once the cylinder is breached, what calamity does the loss of fluid cause?
Answer: uncontrolled down movement of the elevator

Question: Before the code change was enacted what was the only permitted hydraulic cylinder type?
Answer: single-bottom

Part of the Haunted Mansion attraction at Disneyland in Anaheim, California, and Disneyland in Paris, France, takes place on an elevator. The "stretching room" on the ride is actually an elevator that travels downwards, giving access to a short underground tunnel which leads to the rest of the attraction. The elevator has no ceiling and its shaft is decorated to look like walls of a mansion. Because there is no roof, passengers are able to see the walls of the shaft by looking up, which gives the illusion of the room stretching.

Double deck elevators are used in the Taipei 101 office tower. Tenants of even-numbered floors first take an escalator (or an elevator from the parking garage) to the 2nd level, where they will enter the upper deck and arrive at their floors. The lower deck is turned off during low-volume hours, and the upper deck can act as a single-level elevator stopping at all adjacent floors. For example, the 85th floor restaurants can be accessed from the 60th floor sky-lobby. Restaurant customers must clear their reservations at the reception counter on the 2nd floor. A bank of express elevators stop only on the sky lobby levels (36 and 60, upper-deck car), where tenants can transfer to "local" elevators.

Guests ascending to the 67th, 69th, and 70th level observation decks (dubbed "Top of the Rock") atop the GE Building at Rockefeller Center in New York City ride a high-speed glass-top elevator. When entering the cab, it appears to be any normal elevator ride. However, once the cab begins moving, the interior lights turn off and a special blue light above the cab turns on. This lights the entire shaft, so riders can see the moving cab through its glass ceiling as it rises and lowers through the shaft. Music plays and various animations are also displayed on the ceiling. The entire ride takes about 60 seconds.
