Answer 3

Davy Lamp
The lamp was invented by Sir Humphry Davy in 1816. It consisted of a glass cylinder, within which the flame was further encased in wire gauze so as to permit air to enter but prevent the flame escaping to ignite any inflammable gases which might be present in the mine air.
Davy’s invention has stood the test of time and has been the means of saving innumerable lives. The modern flame safety-lamp, although superior in illuminating power, still owes its safety to the basic principle discovered by him.
The Spinning Jenny
James Hargreaves was born in Oswaldtwistle, England in 1720, he received no formal education and was never taught how to read or write. James Hargreaves worked as a carpenter and a weaver. Legend has it that Hargreaves' daughter Jenny knocked over a spinning wheel and as Hargreaves watched the spindle roll across the floor the idea for the spinning jenny came to him. However, that story is just a legend. Jenny was rumored to have been the name of Hargreaves' wife and that he named his invention after her.
The Steam Hammer
James Nasmyth (born Aug. 19, 1808, Edinburgh, Scot. — died May 7, 1890, London, Eng.) Scottish engineer. Son of the artist Alexander Nasmyth (1758–1840), he is known mainly for his invention of the steam hammer (1839), an important metallurgical tool of the Industrial Revolution. He also devised tools such as a planing machine, a steam pile driver, and a hydraulic punching machine, and he manufactured more than 100 steam locomotives. He retired at 48 to devote himself to his hobby, astronomy.

Answer 7

Who invented spinning and weaving in ancient times?

Many experts agree that primitive gins and spinning
wheels originated in India. The earliest samples of
cotton fabric were found in the excavations of the
Indus Valley. Samples of the most ancient mordant
dyeing technique for cotton fabrics, Kalamkari, were
also found there. The Puranas describe spinning and
weaving that match the modern concept of an industry.
The fibers used for spinning and the fabrics produced
were of the most varied types, unparalleled in any
other country during that period. Pliny's Natural
History informs that India exported to Rome large
quantities of sheep wool, woolen fabrics, colored
carpets, silks, cotton clothes, and fabrics ranging
from coarse canvas to textiles of the finest texture.
Ancient Indians had the reputation of making the
thinnest saree that could pass through a finger ring.
During the reign of Julius Caesar, the Roman Emperor,
the British did not know weaving and lived naked.
