2/7/1698, Thomas Savery patented an early steam engine. See also railways, 1699. This engine could be used to pump water out of mines, an increasing problem as miners went ever deeper. However Savery�s (1650-1715) engine was fairly primitive. It could not pump water up from more than 10 metres below it, meaning it had to be installed deep within mines. This was dangerous as Savery�s engine� was prone to explosions. In 1721 Thomas Newcomen (1664-1729), working with Savery, produced an improved atmospheric engine. The full potential of the steam engine was not realised until James Watt (1736-1819) added a condenser in 1769, with the backing of businessman Matthew Boulton.
60 AD, Hero of Alexandria invented the aeolopile (http://modelengines.info/aeolipile/), a rotating ball full of water with tangential vents that would spin when heated as the steam escaped. It was effectively an early steam engine, but was not put to any practical use.

Cayett�s paper, at 50 cents for 500 sheets, was not cheap; it was impregnated with aloe as a supposed cure for piles. Gradually the cost fell and it became universally used. The term �toilet paper� was first used by the New York Times in 1888.

It worked on the heterodyne principle, that a combination of two radio high frequency sound waves could combine to produce a lower frequency audible sound equal to the difference, As the high frequency waves varied, so did the audible sound. The presence of a human body altered the radio waves, which was how the machine could produce changing sounds as a hand was waved over it. The machine was later superseded by the Moog Synthesiser.

28/5/1951, RCA had sued the FCC in an effort to stop the commencement of colour TV broadcasts in CBS format (see 11/7/1949), but this day the US Supreme Court ruled in favour of CBS. However the delay in starting colour broadcasts had been crucial; as in that time many more black and white sets had been sold. When CBS did begin colour broadcasting on 25/6/1951, over 10 million black and white sets could not receive its broadcasts. Viewer numbers and advertising revenues were disappointing, and in October 1951 CBS halted colour transmissions.
29/9/1950, The first automatic telephone answering machine was tested by the US Bell Telephone |Company.
11/7/1949, In the USA, the Federal Communications Commission (FCC) began hearings regarding the possible introduction of a colour TV service. There were three possible systems, the Field Sequential Method of CBS, the Dot Sequential approach of RCA, and the Line Sequential proposed by Color Television Incorporated (CTI). The CBS Field System was the simplest, and produced better quality images than the other two methods, so in 1950 the FCC adopted the CBS method. However the CBS approach was incompatible with current black and white TV sets, whereas the other two methods were not, see 28/5/1951.
25/8/1949. The UK began experiments with colour TV transmission.

12/11/1927. The first automatic telephone exchange opened, in Holborn, London.
27/1/1926. Scottish inventor John Logie Baird, aged 38, demonstrated the principle of transmitting moving images by radio. The demonstration was to members of the Royal Institution, at his workshop in Soho, London. He called this �television�.

12/2/1924, Calvin Coolidge became the first US President to deliver a speech on radio.
30/11/1924, Radio photographs were first transmitted from Britain to the USA.
26/7/1923, John Logie Baird patented a system for transmitting pictures by �mechanical television�. The transmitter and receiver both had a spinning disc with 24 holes; pictures were sent by photoelectric cells. The principle was the same as making repeated static images �move� by rapidly flicking the pages of a book; the persistence of images in the human eye gives the illusion of motion. Unfortunately the picture quality was mediocre, the flickering gave viewers a headache, and the intense light needed to film anything was exhausting for the cast.
2/8/1922. Death of Alexander Graham Bell, aged 75, at his home near Baddock, Nova Scotia. He was born on 3/3/1847 and patented the telephone on 7/3/1876.

With his assistant Thomas Walsop, Bell began making improvements to the telegraph system, and formed the Bell Telephone Company in 1872. Bell also invented the photophone transmission of sound, precursor of fibre-optics, as well as techniques of teaching speech to the deaf.

10/3/1891, US undertaker Almon Brown Strowger patented the Strowger Switch, enabling automated dialling. He was motivated by the fact that the wife of a rival undertaker worked at the local phone exchange, and was diverting calls for his business to her husband.

6/12/1877. Thomas Alva Edison made the first recording of a human voice. He spoke Mary had a little lamb into his phonograph. Edison was working to improve the efficiency of the telegraph transmitter, and noticed that the machine gave off sounds resembling the spoken word when played at high speed. He wondered if he could record a telephone message. He attached the diaphragm of a telephone receiver to a needle, using the needle to prick paper to record a message. He then progressed to using a cylinder wrapped in tinfoil instead of paper, which succeeded in playing back the nursery rhyme he had recorded.
