Starting in the fall of 1939. Bell Telephone Laboratories developed a series of lecture aids that could be used to to demonstrate scientific discoveries and inventions. Project Echo was NASA’s first experimental communications satellite project. With the launch of Echo 1A in August 1960, Project Echo marked America`s entrance in the Space Race. It involved designing, building and deploying passive communications satellites. It also proved that microwave transmission to and from satellites was feasible and demonstrated the potential of communications satellites. En 1939 Bell Telephone Laboratories a construit une série d'aide conférences qui était utilisé pour démonter des découvertes scientifiques ainsi que des inventions. Projet Écho était le premier projet incluant une expérience en communication pour les satellites conçu par NASA. En aout 1960 le Projet Écho 1A à commencer et a marqué le début de la course à l'espace pour l'Amérique. Il impliquait la conception, construction et le déploiement de communications passives avec des satellites. Il a fini par prouver le la transmission à des satellites et des satellites étaient possibles avec l'utilisation des micro-ondes. L'expérience démontrais l'enfance de la potentielle pour la communication avec l'utilisation des satellites.
Function
This artifact was used to house the antenna and its components for both protection as well as travel. Cet étui était utilisé pour une antenne et toutes ces composantes ainsi que pour la protection de ces composantes pendant le transport.
Technical
This horn-reflector receiver is part of the Bell Laboratories Project Echo Lecture Aid, also known as Lecture Aid 214. It was designed to receives microwave signals generated by the lecture aid’s parabolic-dish transmitter. The signals were bounced of a hemisphere affixed to a photo-mural depicting the nighttime sky, demonstrating space communications. Unlike conventional antennas, the horn-reflector design made it possible to receive radio energy from essentially one direction. This resulted in a greater concentration on the desired signal and less interference from other directions and the ground. Le receveur en forme de cornet fait partie des aides conférences pour le Projet Écho et est nommée Aide de Conférence 214. Il était conçu pour recevoir des signaux de micro-onde généré par le transmetteur en forme parabolique. Les signaux rebondissaient sur un hémisphère fixé. A un mural de photo qui démontait le ciel le soir et pouvait ainsi prouver les communications avec l'espace. Le cornet à réflexion était unique, car sa fabrication lui permettait de recevoir de l'énergie a radio essentiellement dans une direction. Ceci avait comme résultat une concentration supérieure du signal désirée et moins d'interférence du sol et toutes autres directions.

Finish
A black synthetic covered case with two metal latches and three metal hinges on its spine. A leather covered handle is attached to its lid with metal fasteners. A manufacturing plate is also visible on the top of the lid. Eight metal corner covers are visible on the object as well as white lettering on both its front and back. The inside of the case has a small leather handle that raises a synthetic divider that opens thanks to a set of metal hinges to reveal a box inside of it. Un étui synthétique de couleur noire qui a deux loquets en métal sur sont devant qui ouvre le couvercle de l'étui avec l'aide de trois charnières à l'arrière du couvercle. Une manche en cuir est attaché au couvercle avec des pièces de fixations en métal. Une plaque du fabricateur est aussi visible sur le dessus du couvercle. Huit couvre-coins en métal sont visibles sur l'objet ainsi que du lettrage blanc sur le devant et le dos de l'artefact. À l'intérieur de l'étui il y a une petite manche en cuir qui peut aider à lever un diviseur synthétique qui s'ouvre avec l'aide des charnières en métal pour rendre une boite à l'intérieur visible.
