The Bubbleator was a large, bubble-shaped hydraulic elevator with transparent acrylic glass walls operated from an elevated chair built for the 1962 World's Fair in Seattle. These transparent walls gave the illusion of looking through an actual 'soap bubble' by refracting light to obtain a rainbow-like effect for the riders inside.
Launch loop (not to scale). The red marked line is the moving loop itself, blue lines are stationary cables. A launch loop, or Lofstrom loop, is a proposed system for launching objects into orbit using a moving cable-like system situated inside a sheath attached to the Earth at two ends and suspended above the atmosphere in the middle.
A car is either winched up to the station on the top of the incline where the cable is collected on a winch drum. Alternatively a car is balanced by a counterweight moving along the track in the opposite direction, quite similar to an ordinary lift. [3] [4] Unlike a standard elevator, it can go up tilted grades. It can be used for both ...
The elevator paradox is a paradox first noted by Marvin Stern and George Gamow, physicists who had offices on different floors of a multi-story building. Gamow, who had an office near the bottom of the building noticed that the first elevator to stop at his floor was most often going down, while Stern, who had an office near the top, noticed that the first elevator to stop at his floor was ...
The elevator algorithm, or SCAN, is a disk-scheduling algorithm to determine the motion of the disk's arm and head in servicing read and write requests.. This algorithm is named after the behavior of a building elevator, where the elevator continues to travel in its current direction (up or down) until empty, stopping only to let individuals off or to pick up new individuals heading in the ...
If the bubble is not long enough to encompass the object, especially at slower speeds, the bubble can be enlarged and extended by injecting high-pressure gas near the object's nose. [ 1 ] The very high speed required for supercavitation can be temporarily reached by underwater-fired projectiles and projectiles entering water.
Parallel (up and down escalators adjacent or nearby, often seen in perpendicular areas, metro stations and multilevel movie theaters); Multiple parallel (banks of more than one escalator going in the same direction parallel to banks going the other direction);
Instead of fixing their leaky roof, Denis and Sir Meows A Lot go to Pillow Land where Sir Meows A Lot gets swept up into a fight with a pillow fighting champion. But when giant raindrops start falling from the pillow sky, soaking pillow people and causing panic, Denis realizes it's all his fault and sets out to fix the leak.
