Communist and anti-communist struggles, centered on Cuba, circa 1960. Also some flashbacks to World War 2 and Cold War images.

A pro Betancourt rally in Venezuela. Crowds gathered with signage against Fidel Castro and in support of Romulo Betancourt. Betancourt addresses the crowds from a podium on a stage, outdoors. A man sitting looking at a radio tower. Images of radio control equipment and sign wave signatures on a scope. Scenes of protest and rioting in a Latin American or South American city. Police combating demonstrators. Vehicles overturned. Citizens running through the streets. Crowds being sprayed by fire hoses from moving fire trucks. Close up views of a newspaper "La Prensa" indicating Fidel Castro's support of the Communist party in Peru. Headline, "Fidel Castro Financia al partido comunista Peruano." An inside headline from the same paper reads, "La Embajada de Cuba Distribuye Propaganda Subversica en el Peru" indicating that an Ambassador from Cuba distributed anti-government, subversive propaganda en Peru. What follows are a series of images drawing parallels between Castro and other fascist historical leaders. Castro speaking forcefully, then a cut to historical excerpts from speeches by Hitler and Goebels in Germany during World War II. A scene with Hitler speaking and gesticulating wildly and forcefully, followed by a scene with Castro doing the same. A wooden sign with skull and crossbones and the words "HALT! STOJ!" on it. Prisoners in a German Nazi concentration camp, thin, weary, and huddled near a barb wire perimeter fence circa early 1945. Nikita Khrushchev on a review stand waving his hat to Soviet Army forces marching below him carrying guns with bayonets fixed. Chinese citizen-military forces (possibly early Red Guard) at a rally, with young women and young men raising rifles in the air . Soviet Russian leader Nikita Khrushchev shaking hands with Chinese leader Mao Zedong, Chairman of the Communist Party of China. A group of Chinese workers digging ditches, including men and women Chinese workers. Still image of Khrushchev and Castro embracing. An anti-communist rally in Cuba.

Technicians use various machines to measure properties of knitted fabric.

Domestic science research work by the Bureau of Human Nutrition and Home Economics Service (United States Department of Agriculture). Chief of the Bureau Dr. Hazel K Stiebeling talks about research in the field of textile and clothing. A man brings samples of knitted fabric to women working at a table. A woman lays the samples out. A technician uses a machine to test the fabric for elastic recovery, breaking strength, air permeability, moisture absorption. She tests stretch and comeback by applying tension with weights. A machine used to show how much rubbing a fabric can stand.

Dr. Kenneth Bowles and his team of scientists work at the Jicamarca Observatory near Lima, Peru.

Space research from the ground with a Scatter Radar. Completed construction at the Jicamarca Observatory near Lima, Peru. Hills in the background. Engineers and technicians inside the Observatory. Local Peruvians with technical skills are trained in class. A technician inspects the Observatory transformers. Men make final wiring check in the Condenser Bank. Two men work on an amplifier in the Amplifier Room. Technicians work at pumps and heat exchangers for the water purification and cooling system. Men work with blowers that circulate cool air throughout passage ways in tunnels. Cables and piping in the tunnels. Scientists direct transmitter energy into the antenna. They monitor every function of the operation. Coaxial aluminum piping conducts transmitted and received radio signals through a spark gap and mixer. A man operates the system outside. Energy for the radio signals flows through coaxial piping in trenches. Dipoles in a modular section of the antenna to probe the upper atmosphere in order to measure electron densities. Open wire lines connect two rows of elements. Dr. Kenneth Bowles conducts scientific observation in the Screen Room. He measures the electron density with a transmitter, holds a record of the trace of electron densities. Electron density observations on a monitor. Antenna at the Observatory, hills in the background. A globe rotates.

Communication waves and the relation between power transmitted and received in Space Communications

United States Air Force training film about Space Communications and the related problems and developments. Animation: Planets, remotely controlled unmanned space research vehicles in space. Space communication links between the vehicles and Earth. Radio waves are reflected, refracted and absorbed. An antenna radiates waves that are dispersed. Communication and light waves on the frequency spectrum. Groundwave and Skywave transmission explained. Skywave transmission reflected back to Earth by the ionized layers in the Earth's upper atmosphere. Bouncing of signal in optimal conditions. Spacewave travels from transmitting to receiving antenna, and travels unaffected through the ionosphere into outer planetary space. Depicts laws that govern Line of Sight transmission: Relation between power transmitted and power received, and ideal and regular conditions. Explains the factors involved in the relation between the power transmitted and received. Comparison of communication and light waves. Inverse Square Law explained. The law applied to Space Communication: Signal generated from point source, energy dispersed in shape of sphere, energy spreads over expanding spherical area. Outlines a practical approach to strengthen received power: Directing the radiating energy, and enlarging area of the receiving antenna.
