Highlights of the annual "Car and driver Showroom Stock Car Challenge." Scenes of Lime Rock Park, a road course auto racing track in Connecticut. A large crowd of spectators and racers gathered in the park. Competitors seen tightening wheel lug nuts and and cleaning car windows. Spectators watch as the racers drive through the race track. These races are partially funded by automobile manufacturers who use unmodified cars for racing and evaluate engineering, performances and safety features of the cars. Race drivers check power plants, transmissions, differentials in driving aspects, suspension system, tires and wheels, braking system, body safety measures, emission control system and bumpers of the cars they buy. Peter Gregg gives a demonstration of safety driving measures. Another famous race driver Bob Bonderant, shares his driving experience with driving safety education. Police, ambulance and fire department send their members to driving schools so that students can improve their driving skills and pursue public driving duties. Civilians attend an automobile show where they are made aware about the latest features like rear view mirror, stronger bumpers and improved suspension. Racing scenes of cars careening, throwing up dirt, spinning 180 degrees, coming up on two wheels, and similar events on the track. Police car demonstrates quick maneuver to avoid road hazard.
U.S. soldiers demonstrate decontamination of a combat tank at Aberdeen Proving Grounds in Maryland. A tank moves on. Two soldiers decontaminate the vehicle using a spray. One soldier stands on the tank and decontaminates it. Under carriages heavily encrusted with mud. Two soldiers spreading lime on the ground. A tanker passes through the lime mud slurry. Two soldiers spraying a tank with high pressure water to remove mud from the under carriages. Now they spray the tanks with lime. A water tanker arrives. An aircraft passes over at a low height. A heavy smoke screen in the background. Soldiers wearing cellophane cover.
A U.S. Army training film about decontamination procedures during a war. A thick coat of contaminated solution is swabbed off with kerosene or gasoline. Then a solution of a non corrosive substance is applied. After it evaporates, the vehicle is washed with soap and water and is left to dry. The vehicle is then covered with a layer of oil. Machine guns and artillery are cleaned in the same way. Clothes and rags used for cleaning are then burned or buried. The land is covered with chlorinate lime. Men shuffle their shoes in the lime mixture. They then remove their shoes and clothes with the help of each other. The clothes are spread in air. They remove their socks and underwear and wash themselves in a stream. Then they wear fresh uniforms.
A segment on manufacture of wire products, from a documentary titled ' The Story of Steel'. Shows the preparing of rod for drawing into wires. In the wire manufacturing factory, the wires are dipped into acid bath to remove scale, then a water bath in a giant wooden tub removes acid from the wires. The rod is carried slowly through a spray of water to deposit a fine oxide coating which is of benefit when wire is drawn. A lime bath neutralizes the acid and lubricates the wires. Lime coating is then baked. Workers working in a wire drawing room in a steel wire mill. End of a wire is sharpened on a grinder to point the end. Worker threads wire through die and onto large receiving spool, then cold rods are drawn through a hole in a solid die which reduces their diameter and increases their length. The spinning spools fill with wire rapidly. For safety of workers, the machine automatically stops after sensing a kink in the wire. The kink catches in a loop on a brake handle, and activates the brake.
A film titled 'Decontamination on Armored Vehicles' shows how to test for the presence of a war gas on an armored vehicle and then shows several decontamination procedures. An aircraft in flight sprays a war gas. A tank moves on a field. U.S. soldiers carry gas in a tank and attach it to the wing of the aircraft. The aircraft taxis and takes off. The aircraft sprays war gas over an armored vehicle. The tank covered with the war gas. A U.S. soldier wearing a gas mask puts a mustard chemical in a container and sprays it on specific parts of the tank. A soldier makes a blue mark on the mustard surface. A soldier puts a special chemical through a syringe. A soldier works on the syringe. Two soldiers wearing gas masks. A soldier stands on the tank. The soldier puts a vacuum bottle in the tank and stands holding the vacuum bottle. A soldier sprays DAMC, a non corrosive decontamination agent, on the tank. The tank moves. After two hours, a soldier wearing a gas mask sprays DAMC on the tank. Another soldier sprays the mustard chemical. The tank moves over a mud area. Mud stuck on the wheels is taken as a sample for a test. The soldiers on the tank spray chlorinated lime on the mud. The chlorinated lime in water. The tank moves into water to remove the mud. A soldier removes the mud from the tank. Several decontamination procedures being used. A soldier sprays hot steam all over the tank. Another soldier sprays DAMC . A soldier records the test result.
A documentary depicts the methods of decontamination after the usage of chemicals during a combat. A bridge with liquid agent . Men place a sign which reads 'Danger war Gas'. The men being given instructions about the procedure to be used. Men fill buckets with water. A concrete bridge is washed with water. The water changes into a white vesicant solid after it reacts with the chemical. Chlorinated lime being put in the water and is spread on the bridge. Men spray oil on the contaminated grass and then burnt. A man uses flame to burn the grass. Men use shovels during the burning. Lime paste being used to wash buildings. The troops march in decontaminated area.
