Document Type and Number:
Japanese Patent JP2849052
Kind Code:
B2
Abstract:
A device for accelerating and decelerating one or more objects by introducing pressurized fluid through an injection valve into the bore of a housing. A piston is slidably mounted in the bore and has a cable attached to one side. The cable travels through an aperture near one end of the housing before passing over a first pulley and then connecting to a carrier which holds the object or objects. The cable is selected to be of a length such that the piston will not exit the open end of the bore, which is opposite to the end near where the aperture is located. This creates the possibility of operating the device in two different modes. In the first mode, the pressure of the introduced gas is insufficient to propel the objects past the side of the first pulley that is opposite to the initial location of the objects. The force of the introduced fluid accelerates the piston away from the end of the bore near the aperture, subsequently decelerates the piston after it has changed direction, and then begins the cycle again. When a greater pressure is utilized, the fluid will accelerate the piston and the objects until they pass the first pulley; then decelerate the objects until they stop beyond the first pulley; subsequently accelerate the objects toward the first pulley, creating a perceived negative gravitational force if the movement is vertical; and then decelerate the objects after they have again passed the first pulley.
