The German brothers, Wilhelm and Carl Fein, in Stuttgart have invented the first portable drill several years later. The electric drill we recognize from our tool box today, is actually a later development, from , when Black and Decker have invented the trigger like mechanism which is used to these days in portable electric drills.
Paper used for writing notes was no new invention, but in a Tasmanian stationary company, owned by J. Birchall, and known as the Birchall's of Launceston was apparently the first to bind them together and sell them as the first notepad. For hundreds of years, paper was supplied in loose sheets, the innovativeness of the new invention was the decision to cut the sheets into smaller sizes, back them with a firm cardboard and glue them together at the top — to facilitate the writing and collating of ideas.
When Birchall approached his British supplier, asking them to provide paper bound in that way, they were very reluctant. However, he managed to convince them, and the rest is history. Known as the polymer banknotes, this invention came out of a request by the reserve bank of Australia, which in the late s presented government scientists with a challenge: to create a new banknote that could not be forged.
The request came after Australia introduced a new decimal currency system. The scientists came up with an invention which embedded in the note a transparent plastic panel and a hologram.
The first notes were released for use in , and were not only hard to counterfeit but also much more durable than plain paper notes. The ink and the polymer embedded in them, created a note that would last much longer than traditional banknotes. Some of the notes in usage today are also waterproof, and can be frozen etc, without being harmed. The dual flush toilet, now a staple in many places around the world, was invented in the early s by Bruce Thompson.
It has two separate buttons that allow the dispatch of different quantities of water, when flushing. Other well-known Australian inventions include the clothes drier known as the Hills clothes hoist, the kiwi show polish, and prepaid postage.
