Abstract
The invention is drawn to a nozzle device for gas torches which allows interactive, real-time control of thermoplastic processing and a method of using this device. The device consists of a movable nozzle slide that it attached to the tip of the torch. The nozzle slide can be moved in an upward or downward direction, thereby changing the amount of heat contacting the material.
Claims19
A nozzle device comprising a movable nozzle slide in the form of a cylinder telescopically mounted over a torch tip, said movable nozzle slide being mounted to move in an up and down direction, and a linear variable potentiometer mounted to said nozzle slide for joint movement therewith, and said nozzle slide having a free end extending downwardly below said potentiometer, said linear variable potentiometer measures the position of the nozzle slide and said nozzle slide varies the temperature of the torch on a material which is melted by said torch by adjusting the distance of said nozzle slide to said material being melted, by moving said nozzle slide closer or further away from said material.
