She went about developing 1 herself. Her buddies have been fairly impressed and had her
make equipment for them as nicely. Soon phrase unfold, and she was acquiring orders for
the devices from lodges and eating places. She obtained a patent on her design and style
and went into creation. At the 1893 World's Columbian Exposition in Chicago she gained the
optimum award. Want to know more, please go to sam smith music.
Her buddies talked a good deal about their new machines and soon, Mrs. Cochrane was

Columbian Exposition in Chicago and won the highest award.
Ellen Ochoa, Astronaut and Feminine Inventor

science diploma in physics from San Diego Condition University, and a grasp of science
degree and doctorate in electrical engineering from Stanford University.
Ellen Ochoa created an optical program made to detect imperfections in repeating styles.
Patented in 1987, this program is used for high quality manage in manufacturing. Later on
she patented an optical program which can be used for robotic. To day, Ellen Ochoa has

NASA. Dr. Ellen Ochoa is a veteran of 3 place flights and has logged above 719 hrs in place.
Patsy Sherman Inventor of Scotchgard
In 1952 became 1 of a modest minority of ladies chemists doing work for a main company,
3M in this case.
Patsy Sherman regards the discovery of Scotchgard as a single of her most important
achievements given that many experts had concluded that these kinds of a item was
"thermodynamically impossible." Patsy Sherman said, "We had been making an attempt to

2. produce a new type of rubber for jet aircraft fuel strains, when a single of the lab assistants
accidentally dropped a glass bottle that contained a batch of synthetic latex I experienced
produced. Some of the latex mixture splashed on the assistant's canvas tennis footwear and
the outcome was impressive."
