in July on the Great Fire of London of 1666, which ripped through the heart of the capital destroying thousands of houses and leaving hundreds of thousands of people homeless.

The engine was built in the 1670s, part of the city authorities’ efforts to ensure that such a disaster never happened again. By the time it was acquired by the museum in 1928, only the giant water barrel and part of the metal mechanism of the pump remained. The accurate restoration was possible because a vintage photograph also survived showing the engine in the 19th century, when it was still complete with its undercarriage, towbar and wheels, and the long wooden arms to operate the pump.

It took Croford Coachbuilders in Kent three months to reconstruct the missing parts usingThis invention relates to antennas and more particularly, to slot antennas adapted for use on aircraft and other high speed vehicles.
Due to the high speed of modern aircraft and missiles, it is important that the size of protuberances from the surfaces of the craft be kept small, or possibly eliminated. As all such craft have electronic equipment which require antennas, considerable work has been done toward reduction of the size of such antennas and mounting such antennas flush with the surface of the craft. Antennas employing a slot radiator are particularly useful for flush mounting as the slot is located flush with the skin of the craft and is backed by a cavity within the craft. These slot antennas comprise a slot from which electromagnetic energy is radiated,
