'''1. Patent 3676638: Plasma Spray Device and Method (1972)'''

''Summary:''
The some of the most prominent conditions which separate this earlier device from it's later cousin (found in [[Homework 1]]) are as follows:

* There are significantly more pieces used to assemble the device than in the later device
* The device takes the shape of a hand-held "gun" when fully assembled, whereas the later device is meant to be used in an automated machine
* The material powder is inserted into the gas flow at an earlier point than in the later device
* Plates with helical holes are used to drive the pattern of the flow of gas through the nozzle instead of creating a vortex
* The electric arc is created directly at the end of the cathode, rather than at the end of the nozzle
* The plasma spray gun can only spray powdered materials, whereas the later device can spray both powders and wires/thin plates
* Geometries of the nozzles and internal cavities vary dramatically
