K-84 Trailer
The SCR-784 was a radar set used by the U.S. Army. It was a mobile version of the SCR-584, used to control the fire of anti-aircraft batteries, and mounted on a searchlight trailer called a K-84. The set was used to guide the flare plane over the target.

G-numbers
This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – ''one'' of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as part of the Ordnance Provision System, from about the mid-1920s to about 1958. In this, the ''Group G'' series numbers were designated to represent "tank / automotive materiel" – the various military vehicles and directly related materiel. These designations represent vehicles, modules, parts, and catalogs for supply and repair purposes. There can be numerous volumes, changes, and updates under each designation. The Group G list ''itself'' is also included, being numbered G-1. Generally, the G-series codes tended to group together "families" of vehicles that were similar in terms of their engine, tr ...

Military Radars Of The United States Marine Corps
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction, prot ...

Analog Computers
An analog computer or analogue computer is a type of computation machine (computer) that uses physical phenomena such as Electrical network, electrical, Mechanics, mechanical, or Hydraulics, hydraulic quantities behaving according to the mathematical principles in question (''analog signals'') to Scientific modelling, model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude (digital signals). Analog computers can have a very wide range of complexity. Slide rules and nomograms are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated. Complex mechanisms for process control and protective relays used analog computation to perform control and protective functions. Analog computers were widely used in scientific and industrial applications even after the advent of digital computers, because at the time they were ...

World War II American Electronics
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Gun Laying Radars
A gun is a device that propels a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns or cannons), or gas (e.g. light-gas gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Tasers, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. Guns were designed as weapons for military use, and then found use in hunting. Now, there are guns, e.g., toy guns, water guns, paintball guns, etc., for many purposes. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within a barrel tube (gun barrel), produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Signal Corps Radio
Signal Corps Radios were U.S. Army military communications components that comprised "sets". Under the Army Nomenclature System, the abbreviation SCR initially designated "Set, Complete Radio", but was later misinterpreted as "Signal Corps Radio." Nomenclature The term SCR was part of a nomenclature system developed for the U.S. Signal Corps, used at least as far back as World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to .... Three-letter designators beginning with "SC" were used to denote complete systems, while one and two-letter designators (such as "BC", for basic component, "FT" for mounting, etc.) were used for components. Only a few system designators were used: :::SCM Set, Complete, Meteorological :::SCR Set, Complete, Radio :::SCS Set, Complete, System S ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Fruehauf Trailer Corporation
Fruehauf Trailer Corporation, previously Fruehauf Trailer Company (1918–1963) and Fruehauf Corporation (1963–1989), was an American company engaged in the manufacture and sale of truck Semi-trailer, trailers, and other machinery and equipment, with headquarters located in Detroit, Michigan. It was founded in 1918 in Detroit, after August Fruehauf created the semi-trailer and launched a new industry. The Fruehauf trailer company introduced revolutionary inventions to trucking and transportation with hydraulic dump trailers, bulk tanker trailers, and automatic fifth-wheel couplings among their more than one thousand patents, including the shipping container in 1956. Expanding across the country, Fruehauf had 16 plants and more than 80 distributorships for parts and service. Globally, the company expanded into Europe, South America, and Asia. Following a proxy battle in the late 1980s the company filed for bankruptcy protection in 1997. International divisions became independent, ...
