Johann Friedrich Dieffenbach was a German surgeon. He was born in 1792 at Konigsberg and died in 1847. After having studied at Bonn and Paris he settled in Berlin, where his talent as an operator soon attracted notice. Surgery is particularly indebted to him for new methods of forming artificial noses, eyelids, lips, etc, and curing squinting, stammering, etc. Research Johann Dieffenbach
Sir Richard Arkwright was an English inventor. He was born in 1732 at Preston, Lancashire and died in 1792. The youngest of thirteen children, he was a barber by trade, while travelling the country dealing in hair for wigs he became interested in the slow and clumsy processes used for spinning and weavingcotton, and when about thirty-five years of age he gave himself up exclusively to the subject of inventions for spinningcotton. The thread spun by Hargreaves' jenny could not be used except as weft, being destitute of the firmness or hardness required in the longitudinal threads or warp. But Richard Arkwright supplied this deficiency by the invention of the spinning-frame, which spins a vast number of threads of any degree of fineness and hardness, leaving the operator merely to feed the machine with cotton and to join the threads when they happen to break.
His invention introduced the system of spinning by rollers, the carding, or roving as it is technically termed (that is, the soft, loose strip of cotton), passing through one pair of rollers, and being received by a second pair, which are made to revolve with (as the case may be) three, four, or five times the velocity of the first pair. By this contrivance the roving is drawn out into a thread of the desired degree of tenuity and hardness. His inventions being brought into a pretty advanced state, Richard Arkwright removed to Nottingham in 1768 in order to avoid the attacks of the same lawless rabble that had driven Hargreaves out of Lancashire. Here his operations were at first greatly fettered by a want of capital; but two gentlemen of means having entered into partnership with him, the necessary funds were obtained, and Richard Arkwright erected his first mill, which was driven by horses, at Nottingham, and took out a patent for spinning by rollers in 1769. As the mode of working the machinery by horse-power was found too expensive he built a second factory on a much larger scale at Cromford, in Derbyshire, in 1771, the machinery of which was turned by a water-wheel. Having made several additional discoveries and improvements in the processes of carding, roving, and spinning, he took out a fresh patent for the whole in 1775, and thus completed a series of the most ingenious and complicated machinery. Notwithstanding a series of lawsuits in defence of his patent rights, and the destruction of his property by mobs, he amassed a large fortune. He was knighted by George III in 1786.

Thomas Alva Edison was an American businessman. He was born in 1847 and died in 1931. He was poorly educated, became a news-boy on the Grand Trunk Railway, and afterwards having obtained some type, issued a small-sheet newspaper of his own on the train. He then set himself to learn telegraph work, and in a short time became an expert operator. While at Indianopolis, he invented an automatic telegraph repeater. He later operated a firm of fifteen scientists who invented the carbon filament electric lamp and the phonograph, although he took full credit for their work. Research Thomas Edison
Dorothy Lamour (real name Mary Leta Dorothy Slaton) was an American beauty queen, singer and actress. She was born in 1914 at New Orleans, Louisiana and died in 1996. She was Miss New Orleans in 1931 and later a lift operator, band vocalist and radio performer before making her film debut in 1936. Research Dorothy Lamour
The Holgar Neilsen method is a method of artificial respiration introduced during the late 1950s by the Danish Red Cross Society and similar in principle to the Silvester method except that the patient lies face downwards. Inspiration (chestexpansion) is produced by lifting the arms upwards over the head, and expiration is produced by the operator compressing the chest with hands placed over the patient's scapulae.

The Bofors 40 Mk3 gun is a 40 mm Naval multipurpose gun with the capability to engage all types of targets. This extremely accurate gun is capable of firing any 40 mm L/70 ammunition, but the highest performance is achieved when using Bofors 40 mm 3P ammunition. The ready-to-use magazine holds a total of 101 rounds, enough for between ten and twenty engagements without reloading. The two magazine compartments can be loaded with different types of ammunition. The operator can, within a split second, switch from one compartment to the other. The Gun Main Computer (GMC) has a built-in event/activity recorder which continuously monitors all the gun-sensors, power supplies and other vital gun functions. The gun is designed for total remote control from the ship Fire Control System. Internal communication within the gun, as well as communication with other units outside the gun, is conducted via a data bus MIL-STD-1553 B. The gun features a sophisticated local control back-up mode using a low-light TV sight. Research Bofors 40 MK3
Cerbere is a French, twin, power-operated, single-operator towed anti-aircraft gun fitted with two 20 mm F2 cannons. Cerbere operates by delayed blowback and fires 900 rounds-per-minute from a dual disintegrating link belt to an effective range of 2000 metres with a muzzle velocity of 1050 meters-per-second. Cerbere is based upon the German Rh 202 AA Gun, but is fitted with F2 cannons in place of the German Rh 202 cannons. Research Cerbere AA Gun
In firearms, a clip is a method of loading some rifles, particularly the US Garand and Mannlicher series. A clip differs from a charger in that the entire unit, cartridges and metal frame, are inserted entirely into the gun's magazine and the metal frame is only discarded when all the cartridges have been fired. Clip-loading rifles suffer from two distinct drawbacks. Firstly, the magazines cannot be partially reloaded. The operator must wait until the magazine is empty before fully loading it. Secondly, the discarded clip provides an audible signal to the enemy that the operator's weapon is empty. Research Clip
Detecting set L4A1 was the British Army designation for the Plessey P6/2 Metal detector range.
The P6/2 equipment consisted of a waterproof electronic unit and a set of operator-interchangeable waterproof probes. The operating mode was pulsed induction. Target detection was indicated audibly by a loudspeaker or plug-in earphone(s). Switched sensitivity and response times were provided. Power was supplied from internal batteries or an external source via an adaptor. An in-built battery check was provided. The function switch, loudspeaker, probe and earphone sockets wee located on a control panel at-the top of the electronic unit. The electronic unit was carried in a slung webbing haversack for manpack operation.
Four types of probe were provided as standard, each for a specific purpose. A connection cable terminated in a quick release plug is integral with each probe.
P6A/2 was a tubular ferrite probe suitable for searches in bushes, streams and rugged urban and rural environments.
P6E/2 Open Loop Probe was a lightweight probe, for ground search applications.
P6F/2 was a short robust probe for general searches in restricted environments.
P6G/2 was a light easy-to-use probe designed for the searching of persons.
Plessey could also supply special probes that could be designed for particular applications e.g. the P6C/2 sledge probe.
The P6/2 equipment was designed to perform over the frequency range 50 to 500MHz. When fitted with a P6A/2 or P6F/2 probe and an MDA7/2 earpiece the P6/2 was capable of operating within four metres of a 1W, handheld radio transmitter or within six metres of a vehicle-mounted 10W radio transmitter without malfunctioning, blocking, or causing interference to the receiver in the radio station.
Typical detection range for the P6E/2 Probe was approximately 220mm with a 2p coin or 250mm2 copper, 18 G and approximately 400mm with a pistol Research Detecting Set L4A1
