Inventions Between 1900 and 1930

the prison term period between 1900 and 1930 power saw many a(prenominal) technological innovations, from the melodic line conditioner to the disposable shave blade. From the cooler to the cruise missile. Many of these inventions do our lives easier maculation others do them more deadly. the front of these inventions is the diffuse conditioner. While many inventers forrader had made crude means of chill the dividing line, alone all proved to be ineffective. the earliest method of cooling the air was putting bowls of ice in front of a fan and the resulting cool air cooled the room.On July 17th 1902 a new-fashioned college graduate, Willis Havilland Carrier drew the plans for his initiative frame-up for treating air which was granted its first glaring in 1906. this great leap forwarfared in valet de chambre comfort was very first made for a belief press where when it got humid it would cause the sign to smear. Carriers method of cooling the air problematic using coiled copper tube-shaped structure filled with liquid ammonia, which when air was winded over the coils would cause the moister to condensate boastful him cool dry air.Cooling for human comfort, sooner than industrial use, began in 1924, displayed by the triad Carrier air conditioners installed in the J. L. Hudson part Store in Michigan. in revise to escape the heat the shoppers of Detroit all went to the air conditioned store. The rise in human cooling spread from the department stores to the ikon theaters. It was a cool oasis in an other wise calorific world. single of the more deadly inventions of the early 1900s is the army tank.The tank got its name because early in WW1 duration it was under development the British didnt neediness the Germans to find out what they were making so they shipped them as water tanks. While no one person can be credited with the invention of the tank it was the British who first employ the tank in WW1. To come up with ideas for the tank , the Landship Committee was organise and their recommendations were that a vehicle firing a explosive shell should be made that could cross a standard German trench of 8 feet wide, and a 4 foot hill.Various designs were tried ranging from vehicles that walked to gigantic powered tires, but none were really successful, or strategically sound. then came the infinitesimal Willie. the little Willie was the first modern variance of a tank it was based on the tracks of do work equipment and earth moving machines. even though the little Willie was the first modern version of a tank it never saw combat as it was surpassed by an improve tank named big Willie. Big Willie was the first practical example of a tank as it was the first to be used on the battle field.With a fall speed of 3 mph and outfit up to 3 inches thick it was non the fastest nor best looking war machine out there but it did its job of providing cover for selliers storming enemy trenches. Although infinitesimal Wil lie never saw combat and was rid almost as soon as it was made, it represented a major whole tone forward in early 1900s technology. In contrast to the tank you have the mint Aid. Earle Dickson was employed as a batch buyer of cotton for Johnson &038 Johnson when he invented the stria-aid in 1921.The reason that Earle invented the band aid was that his married woman kept cutting her fingers in the kitchen while preparing food. The precursor to the band aid consisted of gauze bandage and coherent that the user applied themselves. Earle took a piece of gauze and stuck it to the middle of a piece of tape, and then covered the adhesive and gauze with a strip of crinoline, to move it sterile. His boss, James Johnson, saw Earle Dicksons invention and unflinching to manufacture band aids to the open and make Earle Dickson vice-president of Johnson &038 Johnson.However ingenious his invention was it was mute to start. Until Jonson and Johnson started to give them to the boy scou ts for free as a P. R. stunt and by 1924 band aids were machine made and sold in individually wrapped bandages, it wasnt until 1934 that they switched to the vinyl group tape we know today. The thirty long time that followed the turn of the century saw just about of the most technological advancements ever seen. From the air conditioner to the band aid, without the inventers of the early 1900s the world would unperturbed be stuck in a hot bloody band aid free world.
