Hello, you can use mine as information, thank you
Nobel built a small pier extending into the sea in Sanremo to conduct explosives and firearms experiments ; He worked there for five years in a highly stressful manner. The basic work of several important inventions that Nobel did not complete during his lifetime was done there; later, these inventions were successfully tested by others and played a role in promoting some major events. Nobel's final discovery in the field of explosives, the so-called "improved smokeless explosive" (the first invention patent registered in Sweden is No. 7552 of 1896), is a hybrid smokeless explosive further developed to suit certain special purposes. Smoke explosives were created in this laboratory. If we want to thoroughly explain this invention, we need to involve the technical details of cannons and internal ballistics; so here we can only simply say that its purpose is to "increase the muzzle velocity of the projectile without increasing the maximum pressure inside the weapon." ; This is done by inducing a certain increased incremental force in the burning of the explosive, so that as the projectile advances within the gun chamber, the pressure is maintained and the overall ballistic action increases the consumption of explosive for this advance. From two aspects: mechanically, through the progressive increase of the surface layer of the explosive pellet during the combustion process; and chemically, through the individual explosive pellets, which are made into various layers. The various layers allow the inner layer to have a greater burning rate, thereby increasing the effect during the combustion process."
The manufacture and testing of improved explosives began in several factories of Nobel. It was carried out between 1895 and 1896 in the inventor's new Swedish laboratory in Bjerkborn, near Bofors. Nobel's interests as an inventor were by no means limited to dynamite. He had a high degree of imagination, which is an indispensable quality for those true inventive geniuses. Not only was he capable, but he was also eager to apply his brilliant ideas to the things around him. This includes a wide variety of subject and applied chemistry - electrochemistry, optics, mechanics and artillery, biology and physiology. These mentioned are only subjects in the fields of technology and natural sciences. Like his father Emmanuel, his creativity sometimes went as far as the whimsical. This is usually done in a split second, on purpose. According to his aides, he sometimes couldn't draw the line between fanciful ideas and epoch-making inventions. It is, of course, more difficult for him to draw this line when his knowledge of a subject is shallower, such as the construction methods of certain cannons, or certain biological and physiological problems. As the years went by, Alfred Nobel turned many of these diverse ideas into patented inventions. The total number of invention patent rights he applied for and obtained cannot be stated accurately; but the registration form with a similar number produced when liquidating his property included no less than 351 patents he had obtained in various countries. Invention patent rights, this is an amazing number coming from a mind.
