Stepped firing

Natural gas forms flammable mixtures with air in the concentration range 5-15 per cent in air. In the event of a natural gas fire, steps should be taken to shut off the gas supply, and the local fire brigade and the gas supplier notified. 

Although the electrode performance can be improved by the introduction of compositional and microstructural gradients into the anode or cathode, the processing required to produce such graded layers also increases in complexity as the number of discrete layers increases, particularly when separate deposition and firing steps are required for each increment in layer composition or structure. 

In summary, the main advantages of thick-film technology are the high-conductivity conductors and the relatively inexpensive process equipment, whereas the drawbacks are the limited number of layers, the multiple printing and firing steps, the low conductor line resolution, and the limited dielectric thickness. 

Manufacture.The following method is typical An oven is constructed with stones in the shape of a well. The inside diameter of the oven is determined so that the hemp caules can be easily inserted. At first some of the hemp caules are ignited and thrown into the oveii, and then the remainder of the caules are heaped on the fire step by step at intervals so that the material thrown in at first does not become ash. Finally, water is poured on the hemp to extinguish the fire. The hemp coal thus produced is dried by itself from the remaining heat. Finally it is crushed to a fine powder and sieved to remove coarse grains and foreign matter. 

This Light preferably makes use of the Air as a carrier, through which it maintains the Life of all Creatures. While the Air condenses itself into a rain or dew, the living Fire steps secretly with the Water into the Earth, where it takes on a Salt-Body, which is a physical Water or a fixed Fire that has with the living volatile Fire the greatest inclination, because it requires the same as nourishment.
