In cases where these groupings correspond with major groups, the major group heading is also in italics. The assembly of products from component parts is considered to be Manufacturing, except in cases where the activity is appropriately classified under Construction. The assembly and installation of machinery and equipment in mining, manufacturing, commercial and other business establishments is classified under the same group of Manufacturing as the manufacture of the item installed. Excluded is the assembly on site of prefabricated, integral parts of bridges, water tanks, storage and warehouse facilities, railway and elevated pedestrian bridges, and lift, escalator, plumbing, sprinkler, central heating, ventilating, air-conditioning, lighting and electrical wiring systems for buildings and mines and all kinds of structures which are construction activities if undertaken as a specialised activity. Establishments specialising in the installation of household appliances, such as stoves and ranges, refrigerators, washing machines and driers, are classified under the appropriate retail trade group. The manufacture of specialised components and parts of and accessories and attachments to machinery and equipment is, as a general rule, classified under the same group as the manufacture of the machinery and equipment for which the parts and accessories are intended.

More sophisticated than the Alouette spacecraft, ISIS is designed to make a comprehensive study of the upper section of the ionosphere, and to capture the first picture of the aurora borealis northern lights from space. EDT on this historic Sunday, U. Fifteen minutes later, Buzz Aldrin climbs down the ladder of the lunar module to join his commander. September 1, The federal government announces the creation of Telesat Canada to own and exploit Canadian communication satellites.
The government also sets up a Department of Communications that immediately takes over the Communications Research Centre formerly Defence Research Telecommunications Establishment and the Interdepartmental Committee on Space. In , years after all Canadian research needs have been fulfilled, the operation of the two ISIS spacecraft is transferred to Japan for additional research.
July 26, First Landsat-1 remote-sensing image is acquired in Canada, at the Prince Albert receiving station. The laboratory is named in honour of C. September 30, Alouette 1 ceases activity nine years after its planned termination. November 9, The Anik A1 communications satellite is launched. Canada is the first country with a domestic communications satellite in geostationary orbit.
April 20, Launch of Anik A2, Canada's second communications satellite. Anik A2 is launched to bring network radio, TV and improved telephone services to Canadians living in the North. The result is Canadarm , the metre robotic arm. May 7, Anik A3 is launched on a Delta rocket. Telesat Canada accomplishes another world first by teaming Anik A3 with A2 in the same orbital position to permit the still usable channels on each satellite to be operated as if they were onboard the same spacecraft.

Canada signs an agreement with European Space Agency to participate in the development and exploitation of Olympus, the largest hybrid communications satellite launched by Western countries. August 26, Anik D1 is launched atop a Delta rocket. The more capable D series will replace the A and B series, and form the backbone of Canada's domestic satellite communications system until the early s.
This is the beginning of the Canadian astronaut program. November 12, Anik C3 is deployed out of the cargo bay of Columbia during the first commercial mission of the space shuttle mission STS Anik C3 carries the equivalent of 32 colour television channels and 21, voice circuits. It is the world's first direct broadcast satellite for commercial use, and is more powerful than the previous Anik series, allowing the use of smaller, 1. June 23, With the help of a payload assist module, Anik C2 is deployed out of Challenger's cargo bay, five days into mission STS C2 followed C3 into orbit because satellites are numbered according to when they are built, not when they are launched.
Sally Ride is the first American female astronaut in space. Canadarm is used for the seventh time on a space shuttle mission to support spacewalking astronauts and to deploy the Long-Duration Exposure Facility LDEF. This is a platform the size of a school bus that contains 57 materials experiments; three trays are from Canada. On this mission, Canadarm is operated for the ninth time on a space shuttle flight. With sister satellite D1, launched in , it is one of the biggest communications satellites of the time.

Jump to navigation. Objectionable Programming. It provides a brief overview of the regulation of broadcast radio and television licensees, describing how the FCC authorizes broadcast stations, the various rules relating to broadcast programming and operations that stations must comply with, and the essential obligation of licensees that their stations serve their local communities.
Mechanical television or mechanical scan television is a television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with modern television technology, which uses electronic scanning methods, for example electron beams in cathode ray tube CRT televisions, and liquid-crystal displays LCD , to create and display the picture. Mechanical-scanning methods were used in the earliest experimental television systems in the s and s. One of the first experimental wireless television transmissions was by John Logie Baird on November 25, , in London.

How the Moon Landing Was Filmed
Detailed in his patent, No. Less than two decades later, during the First World War, the Germans employed a remote-controlled motorboat packed with explosives and attached to an unspooling wire. Radio-controlled and limited-range tanks, bombers, and guided missiles were deployed by the Russians, Germans, and Americans during the Second World War, with their use expanding as the war progressed. Drawing on the advances made by the military, commercial electronics companies began experimenting with more anodyne applications, ushering in the age when remote control became a handy device intended to make life easier for consumers.

A television studio , also called a television production studio , is an installation room in which video productions take place, either for the recording of live television to video tape , or for the acquisition of raw footage for post-production. The design of a studio is similar to, and derived from, movie studios, with a few amendments for the special requirements of television production. A professional television studio generally has several rooms, which are kept separate for noise and practicality reasons. These rooms are connected via ' talkback ' or an intercom , and personnel will be divided among these workplaces.
Luna 9 was the first soft landing mission on the moon. The Soviet spacecraft arrived three years before the first humans stepped out on the surface. It was part of a long-range Soviet Union program to photograph and learn more about the moon. In the s, the United States and the Soviet Union were engaged in a "space race" that ultimately saw the Americans land the first humans on the moon in The Soviets were unable to get their Zond rocket program going, even after a series of test flights. One blew up on the launch pad in and killed several people.

At the heart of any studio is the audio console sometimes called a radio panel, sound panel, or sound desk. The fader slider attenuates or amplifies the incoming signal. A microphone captures sounds from the studio and turn it into electrical impulses. Studio microphones are often mounted on a special arm that keeps the microphone at the correct height.
Он уходил корнями в давние времена. В эпоху Возрождения скульпторы, оставляя изъяны при обработке дорогого мрамора, заделывали их с помощью сеrа, то есть воска. Статуя без изъянов, которую не нужно было подправлять, называлась скульптурой sin cera, иными словами - без воска.
С течением времени это выражение стало означать нечто честное, правдивое. Английское слово sincere, означающее все правдивое и искреннее, произошло от испанского sin сега - без воска.
Джабба пристально посмотрел на директора и вдруг разразился смехом. - Вирус? - Его грубый хохот разнесся по подземелью. - Так вы считаете, что это вирус. Фонтейн оставался невозмутимым.
