A plethora of companies began introducing water guns to the toy market before the 1980s. No name companies began creating water pistols in the shapes of sea-creatures and cartoon characters, while others introduced more intricate designs from movies like Star Trek and Rambo. One company, Entertech, even went so far as to produce battery-powered water weapons but the designs proved to be a little too life-like. The water guns began resembling real live machine guns like those used by G.I.'s and some even came equipped with a back pack and grenade devices. The water weaponry market continued evolving, and soon enough, perhaps the most important contributor, Lonnie Johnson, came into the picture. A nuclear engineer, who, in 1982, thought …show more content…
He came up with the model for this "power drencher" which has various nozzles at different angles and a pressurized water system (this model was called the Super Soaker MDS - multidirectional soaker). Johnson connected this device to his bathroom sink at home and after the stream of water shot across the bathroom, he realized it would become a success. After approaching Larami Ltd.. with this creation, the deal was sealed. "Released in 1990 and still being produced today, the Super Soakers revolutionized water guns forever by using compressed air to shoot out powerful blasts of water"(RoG). These new models could hold more water and shoot farther than any other on the market. "In 1992, Larami sold many types of water guns based on the pressurized reservoir and separate pressurized firing chamber models" (Bergen). The shooter holds the gun, pumping the handle to create pressure and pulls the trigger to release a powerful stream of water that can squirt up to 30 feet and drench opponents. Super-Soakers have evolved over the years and some "look like they're more suited for battling invaders from Mars than getting your pals soaking wet." (RoG) The only downside of these toys is that fact that they've been remodeled plenty of times, to the point where the gun becomes to heavy for a child to carry and use, once filled with water. Regardless of how they've evolved in this past decade, though, these "insano-powerful water blasters" are still popular today and rule the squirt gun market (RoG). Lonnie Johnson and Larami Ltd. have over 2,000,000 in Super-Soaker sales.

The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown into a tank which probably looks something like this.
The amount of ammunition that is allowed by law to be loaded into a firearm criminalize many popular handguns, even those used by the military like the Beretta m9 9mm, which is the standard issue side arm of the United States military that has an ammo capacity of a whopping 15 bullets. 16 bullets if one is locked in the chamber. According to this new law only seven are allowed to be loaded at any given time except when in a competition on a range.
Johnson was put into office as the 36th president of the United States after the assassination of President John F. Kennedy in November of 1963, his first task was one close to his heart, which was to alleviate poverty and create what he called a “Great Society” for all Americans. This is where Medicare and the Head Start program came from which led to better healthcare, education, urban renewal, conservation and civil rights. Despite his amazing achievements at home in the US, he was also known very well for his failure to lead the nation out of the devastation of the Vietnam War which was travesty from 1954 to 1975. It was after this that he decided not to run for office again and he quietly retired to his ranch in Texas in January of 1969 (History.com Staff.
Well it's quite simple actually. Spudguns use some of the same principles as internal combustion engines. Just as burning gas forces a piston out of a cylinder it can also force out a potato. A spudgun is a device that uses some form of propellant to project a potato across the sky. Usually these devices are made of ABS plastic sewer pipe. There are several major parts of the spud gun that these pages will refer to. These parts are the firing chamber, the igniter, and the barrel.
Before 1860, the government of the United States provided little interest or encouragement in the inventions of various ordinance experts. The U.S. Ordinance Department generally thought that the United had many preceding wars and battles due to the smoothbore cannon, and thus, no further weapons were needed. Many inventors had spent of years of time and many on this experiments and would face financial crisis if the government did not use them.
Parmelee took the automatic sprinkler head and added to it a fusible link that broke at about 160oF. This allowed the system to control which heads broke so the whole system wouldn’t drown the whole structure in water, it would only release where there was sufficient heat to break a head. Grinnell invented a head that could withstand higher water pressures without breaking, as well as distribute water more evenly. Each of these inventions increased the efficiency of the systems greatly. Now in today’s modern fire protection era, automatic sprinkler systems are used to protect buildings around the world.
Firearms today use cartridges, and cartridges are made up of various parts that all work together to make sure that the
“Volley Guns” (Chivers, 2010, p.26) or also known as “Organ Guns” (Ellis, 1975, p.10) were first attempts at increasing firepower by adding several barrels at the firing itself, rather than simply attempting to increase the rate of fire. “Gunsmiths had long ago learned to place barrels side by side on frames to create firearms capable of discharging projectiles in rapid succession. These unwieldy devices, or volley guns, were capable in theory of blasting a hole in a line of advancing soldiers” (Chivers, 2010, p.26). An example of such weapons can be seen on July 28, 1835 when Giuseppe Fieshi unleashed terror on King Louis-Phillipe in Paris, France. He fired his 25 barrel “volley gun”, killing 18 of the king's entourage and grazing the King's skull. The weapon was ineffective however. Four of the barrels failed and another four ruptured. Two other barrels had exploded inside, grievously wounding Giuseppe. (Chivers, 2010, p. 27)
Hello, the topic we are talking about today in the featured video provided by SDI with the help of SDI Instructor Kip Carpenter is the evolution of firearms and their history. In this film they talked about where the firearms journey started in the 1500's. The first few different types of actions including the old snafus with the match lock system which used a match or a piece of cord but was very unreliable if it was raining. The wheel lock system was a interesting apparatus that worked like a clock mechanism and used a piece of pyrite for the ignition source. This system took 2 hands and wasn't very cumbersome. Soon after that the flint lock system was introduced which was really reliable. It was used for almost 100 years before something

M253 Cannon (barrel): The M253 cannon consists of the barrel, sealed at the lower end with a removable breech plug that houses a removable firing pin. At the muzzle end is a cone-shaped Blast Attenuator Device (BAD) that is fitted to reduce noise.
Supercritical fluids are involved in numerous industrial processes especially food industry and have a potentially wide field of new applications. The current applications of supercritical fluid include extraction processes, reaction chemistry and polymerization, food fractionation, waste recycling, soil remediation, cleaning of electronic and optical equipment parts, impregnation, dry powder coating, aerogels, nanotechnology, and crystallization and particle formation of pharmaceuticals and many other powdered products. In food industry, the most commonly use are in rapid analysis for fat content, rapid analysis for pesticides in foods, detection of food pollutants, encapsulation of liquids for engineering solid products, removal of alcohol
