The early gas mask was made in 1915 by Cluny Macpherson. They were invented to provide protection to the allied soldiers, against the Germans who used poisonous gas to take the opposing team down. Although to their surprise they showed up with a gas mask that was quite weak due to the material they used to make it, yet, still effective to get them through the warfare of the poisonous gas. -
In 1916 the Nissen Huts were developed through WW1 by Peter Norman Nissen. They came in three sizes depending on the capacity of soldiers in each. They were low-priced and easy to put up, nothing too complicated. Typically a 16ft hut could be put up in 6 hours by 4 men. They were made from steel ribs on a concrete base with wooden frames along with sheets of iron nailed to them to be used as spacers. Some huts ended up as temporary housing after WW2. -
During WW1 when soldiers were wounded and would usually tend to lose a lot of blood, Dr. L. Bruce Robertson from the Canadian Army Medical Corps would perform a blood transfusion to revive someone from their many casualties. He would test the blood transfusions near the front line and such as a theory that saline was the rejuvenate choice of fluid in military medicine. -
The Sonar was an important invention designed and built by Reginald Fessenden. It was a crucial element for Canadian ships during wars at sea because it was a device that would detect underwater sound waves to find any sort of dispatches, such as boats, submarines, and mines. The systematization behind the sonar is that it will send out a subsurface sound wave and then listen back for any echoes: all of this data would then return back to the operators where it is displayed on the monitor. -
Wallace Turnbull was the one who designed one of the first outstanding variable pitch propellers. This invention was made to adjust the angle to which propeller blades cut the air. This device became a crucial part of flying any aircraft. It provides both safety and efficiency at all levels; for instance, maximum power on both takeoff and landings; along with traveling far distances. -
For the longest time scientists had always thought that the fundamental aspect to preventing diabetes and controlling a normal metabolism was pinpointed in the internal section of the pancreas. By 1921 Frederick Banting and his medical team from the University of Toronto, conducted many experiments to test their theories which then led to the discovery of insulin: this escorted the way to saving hundreds of millions of lives all around the world. -
In 1925, Arthur Sicard had been developing and finally finished his new up-and-coming device, ``Sicard Snow Remover Snow Blower.`` On the front of the truck was the snowblower feature, a scooper along with a fan that was capable of blowing the snow around 27m away. They became a hit in Montreal in 1927. From this point on, this invention made Canadians day to day life on a winter day easier to get by and remove the snow when needed. -
In 1925 Edward Samual Rogers invented the battery-less radio. The objective of his design was to create a radio that ran off household electricity. Due to the little electricity, it would obtain, the radio became a huge deal and began to sell all over Canada. Throughout WW1 the evolution of communication technology elevated quickly therefore they had to use radio operators with a portable transmitter to alert their soldiers to increase of attack.
