Fourth Rotor
This article contains technical details about the rotors of the Enigma machine. Understanding the way the machine encrypts requires taking into account the current position of each rotor, the ring setting and its internal wiring. Physical design of rotors Image:Enigma-rotor-pin-contacts.jpg, The right side of a rotor, showing the pin electrical contacts. The Roman numeral V identifies the wiring of the rotor. Image:Enigma-rotor-flat-contacts.jpg, The left side of an Enigma rotor, showing the flat (plate) electrical contacts. A single turnover notch is visible on the left edge of the rotor. Rotor electrical view No letter can map to itself, a cryptographic weakness caused by the same wires being used for forwards and backwards legs. Rotor offset The effect of rotation on the rotors can be demonstrated with some examples. As an example, let us take rotor type I of Enigma I (see table below) without any ring setting offset. It can be seen that an is encoded as an , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ratchet Teeth
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a ''pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the opposite ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bletchley Park Naval Enigma IMG 3604
Bletchley is a constituent town of Milton Keynes, Buckinghamshire, England. It is situated in the south-west of Milton Keynes, and is split between the civil parishes of Bletchley and Fenny Stratford and West Bletchley. Bletchley is best known for Bletchley Park, the headquarters of Britain's World War II codebreaking organisation, and now a major tourist attraction. The National Museum of Computing is also located on the Park. History Origins and early modern history The town name is Anglo-Saxon and means ''Blæcca's clearing''. It was first recorded in manorial rolls in the 12th century as ''Bicchelai'', then later as ''Blechelegh'' (13th century) and ''Blecheley'' (14th–16th centuries). Just to the south of Fenny Stratford, there was Romano-British town, '' M'' on either side of Watling Street, a Roman road. Bletchley was originally a minor village on the outskirts of Fenny Stratford, of lesser importance than Water Eaton. Fenny Stratford fell into decline from the Engl ...
