Abstract: A method for roping an elevator. At the bottom part of the elevator shaft the hoisting ropes are routed under the pulleys of the elevator car. Then the elevator car and the counterweight are hoisted to the upper part of the shaft where the first ends of the hoisting ropes are routed through the traction sheave and the counterweight pulleys. After that the first rope ends are fixed to the counterweight side rope terminals and the counterweight is lowered to the bottom part of the shaft. During the descent the hoisting ropes are unwound from the reels through the whole roping system with the help of the mass of the counterweight. Finally, the second ends of the hoisting ropes are fixed to the car side rope terminal and tightened to the correct tension.

Abstract: A lift apparatus for telescopic passenger stairs enabling disabled passengers with impaired mobility to board a plane and to telescopic aeroplane passenger stairs with the said lift. The lift apparatus moves the lift regardless of the degree of extension of the telescopic staircase, with a moveable guide rail installed into a lower staircase, which can travel to the top of an upper staircase if needed. The guide rail in the lower part serves as a fixed guide rail for the lifting platform, onto which a passenger in a wheelchair is wheeled, wherein the platform moves along the guide rail. When the platform reaches the end of the guide rail, it is locked in place, after which the guide rail itself then moves along the track of the upper part of the staircase, wherein it is connected to the guide rail via wheels. The described movement is enabled by a system comprising an endless chain, guide rollers and wheels, a drive sprocket and a drive, and the said guide rail.

Abstract: The Autonomous Oil Change System allows a user to arrive at a station and conduct an oil change on their vehicle. They do so by opening the lid/cover located on the front of the car on the machine to process the payment. This permits the user to insert their debit/credit card on the machine to process their payment and to begin the process and receive an oil change in a few minutes with a receipt and a date recommendation for their next oil change. The system then performs the oil change autonomously. A first hose extends from an oil pan of a vehicle to an externally accessible point on the vehicle. A sensor indicates a level of oil and generates a signal for a pump to draw an oil in the oil pan via the hose externally accessible on the vehicle based on the signal from the sensor.
