Mills bomb rifle grenade by attaching a metallic rod to its base. This rod-type rifle-grenade had an effective range of about 150 yards. The operating procedure was to insert the Mills bomb rod down the barrel of a standard rifle, put a special blank cartridge in the rifle's chamber, place the rifle stock on the ground, then pull the Mills bomb's safety pin, releasing the safety spoon and immediately fire the rifle. If the soldier did not launch the grenade quickly, the grenade's fuse would time out and explode. The British soon developed a simple cradle attached to the rifle's bayonet lug
Science and invention in Birmingham Berners-Lee, a mathematician and computer scientist from Birmingham, works in the team that develops the Ferranti Mark 1, the world's first commercial stored program electronic computer. Berners-Lee is demobilized from the British Army in 1947 with the rank of Major. By the late 1960s Berners-Lee leads the Medical Development Team of ICT and then ICL and is involved in some of the earliest developments in the applications of computers in medicine, and his text compression ideas are taken up by an early electronic patient record system. Berners-Lee later marries Mary Lee Woods (also from Birmingham). Woods studies at Birmingham University
