LORD KELVIN’S PATENTS ELECTRIC BALANCE
MADE IN:glasgow and London, (Lord Kelvin, 1824-1907)
The balance can measure current or voltage using electromagnetic attraction and repulsion coupled with a standard beam balance mechanism.
LORD KELVIN’S PATENTS ELECTRIC BALANCE
William Thomson (Lord Kelvin, 1824-1907)
patented the current balance in 1894. The balance can measure current or voltage using electromagnetic attraction and repulsion coupled with a standard beam balance mechanism.(1) The balance has with it a set of weights and a thermometer that is inserted through the hole in the top of the case and into the right coil. This instrument is an example of a centi-ampere balance. The high current terminals are at the back of the balance.
INDUCTION COIL
It is used to produce high-voltage pulses from a low-voltage direct current (DC) supply
BAGNOLD SUN COMPASS
Innovator
Bagnold also developed a way of conserving the precious water that was lost – usually from an overflow pipe – when vehicle radiators boiled over.
His innovation was to connect the overflow pipe to a can half full of water on the front of the vehicle so that the boiling water would condense in the can. When this water also began to boil over, the driver would turn his vehicle into the wind. After a short time, all the water would be sucked back into the radiator, filling it up again.

Navigation
In an era before satellite navigation a good compass was essential in the barren and featureless North African desert, most of which was unmapped. During his early travels, Bagnold had used a magnetic aero-compass, lent to him by the Royal Geographical Society.
The compass was mounted on his vehicle, but he could not compensate it properly due to the magnetic influence of the car’s metal. Bagnold was often forced to stop his car and take bearings away from the vehicle. He also found that the iron ore deposits sometimes found in desert regions affected this instrument.

Sun-compass
The LRDG also experimented with different sun-compasses. These were unaffected by magnetism, but had to be reset in line with the sun whenever they changed course to traverse rough terrain or avoid enemy troops. This again delayed the progress of their convoys.
Bagnold therefore invented a new sun-compass that could be used while still driving. This worked by turning its disc to match the approximate azimuth of the sun (taken from tables of different dates and latitudes) at regular times.
