- A documentary film which follows a mailman as he travels along the Birdsville Track in the Outback.
- The Mille Miglia, a thousand mile motor race around Italy, starts and finishes at Brescia and passes through Rome, Florence and Bologna. This video documents the twentieth Mille Miglia of 1953. In Italy, where the design and construction of competition cars is a significant industry, the most famous names are Ferrari and Alpha Romeo. Enzo Ferrari was responsible for building the winning cars of the previous five Mille Miglia. Enthusiastic supporters travel to Maranello to see the Ferraris testing for this year's race. At Alpha Romeo, in Milan, designers consider racing as part of a process for developing cars for conventional motorists. Over five hundred cars have been entered for this year's race, with one thousand drivers and co drivers. The competitors are numbered and start one at a time, with the smallest cars first. All vehicles are divided between four touring classes for standard production cars, and four sports car classes. As well as the main race, there is close competition for each class prize. As tension mounts at the start, where cars set off every half minute, the police struggle to contain an enthusiastic crowd. As most of the leading drivers possess the skill and experience to win the race, greatest interest focuses on them. Each car is issued with a card, which the driver must ensure is stamped at control points along the route. After the first 180 miles, the Ferraris have broken every record, with an average speed of over 100 mph. From a control point at L'Aquila, the route descends through the mountains and down to Rome. Special flags are used to warn drivers of hazards, which include unexpected corners, narrow bridges and level crossings that may be closed. Around the circuit, many cars have run into difficulties and some are already out of the race. As the race continues, hundreds of different types and sizes of car compete around the circuit. French cars are leading in both classes on the stretch to Bologna, the last control point before the finish at Brescia. The remaining 140 miles forms the fastest section of the course. On the last leg, Ferrari takes the lead to win, with Alpha Romeo in second, and Lancia third.
- In Search Of History documentary about the history of the indigenous peoples of the Americas. It won the 1975 BAFTA Award for Best Documentary.
- This documentary examines the evolution of gear technology and the uses of gears from their invention to modern day applications. The gear provides the best means for the efficient transfer of power from one direction to another. Today they are most widely used in the control of speed, which is determined by the respective number of teeth on each gear called the gear ratio. The earliest example was the Chain of Pots, first used 2000 years ago. The mechanism worked through crude spun gears raising a horizontal force of water vertically, resulting in the flowing water providing power. Then, from its beginnings in the first century, the vertical or Roman mill, became the major source of power for the next 1800 years. The gears used in the windmills and water mills that powered 13th century industry, were crudely constructed using wood. From the middle of the 14th century, mechanised clocks containing metal gear wheels appeared in Europe. It was established that continuous rolling contact could reduce friction between gear teeth increasing efficiency and reducing wear. Initially the cycloid shape was used, but the involute curve, first proposed in the 18th century, has since become universally accepted as the best profile for gear teeth. The Industrial Revolution brought the widespread use of steam engines. Belts, chains and gears were required to transfer their power. As more powerful engines were developed, gear wheels had to take greater loads. The use of cast iron, the correct tooth shape and adequate lubrication became vitally important. In many industrial machines spur, bevel and worm gears were used to transfer power, and the compact gear provided high gear ratios. Gear cutting machinery became more accurate and in the 1840s, the principle of gear generation was first applied in the USA. The differential gear appeared for the first time on the road in a tricycle and is now a standard feature of the motor car. Today, the internal combustion engine and steam turbines like the one used by Charles Parsons (1854-1931) in the first turbine powered ship in 1897, involve high gear ratios and use single or double helical gears. These are smoother, quieter running and suffer less wear. Motor vehicles and early industrial machines requiring a range of gears used the synchro mesh gearbox. Only the gear in use drives the shaft, while the rest rotate freely. James Watt (1736-1819) originally devised the sun and planet gear in 1871, in which gear wheels of varying size convert vertical piston movement into rotary motion. More recently, the principle has been used in the epicyclic gearbox, which can handle very high power loads.
- A fascinating look at air travel in 1956. From international passenger journeys to the moving of goods and services with a few behind the scenes glimpses of technical aspects of flight, this short film is still enjoyable and surprisingly relevant today.
- This is the first in a series of three educational films entitled "High Speed Flight". This film produced in 1956 looks at the aerodynamics of flight at speeds approaching the speed of sound, using animated sequences to illustrate important physical principles. Sound travels through the air in a series of waves of compression and expansion. Sound waves spread out from their source in all directions and at the same speed, the speed of sound. The speed of sound varies according to the temperature of the air in which it travels. The higher the temperature, the faster sound travels. Since the temperature falls with increasing altitude, so the speed of sound falls with increasing altitude. At high speeds, the exact relationship between the speed of an aircraft and the speed of sound is very important. The ratio of the aircraft's true air speed to the speed of sound is called the aircraft's Mach Number (M). At high speeds it is essential for the pilot to know the Mach Number, so Mach meters are fitted to all high speed aircraft. The behaviour of the air flow around the aircraft during flight is extremely complex. During flight, the air flow slows down at the nose to form what is called the stagnation region. The air then speeds up as it passes round the curvature of the wing and slows down again towards the trailing edge of the wing section. These changes in speed cause changes in air pressure. All the variations in pressure together produce lift and drag. At speeds approaching the speed of sound, the air flow speeds up as it passes over the wing and reaches a maximum speed at a certain point on the wing. The Mach Number here will always be greater than that of the aircraft as a whole, called the flight Mach Number. An aircraft may be flying at less than the speed of sound, but the speed of the air flow at the point on the wing may be moving at the speed of sound. The flight Mach Number when this happens is called the Critical Mach Number of the aircraft. When the wing exceeds its Critical Mach Number, a sudden sharp region of increasing density forms on the wing. This is called a shock wave. It is a very narrow region where the pressure waves caused by the moving aircraft meet the air flow moving in the opposite direction, causing a pile up of air. At speeds approaching the speed of sound, the most important result of the shock wave is to cause the air flow to spread from the wing's surface. This is called shock induced separation. It produces a large turbulent wake that alters the pressure distribution. Violent buffeting may occur or there may be a sudden loss of stability and reduced effectiveness of the controls. Two main wing designs have been adopted to reduce the problems of extra drag and loss of control caused by shock waves. The first is to use relatively thin wings. The thinner the wing, the less the air accelerates, which delays the onset of the shock wave. The second is to incorporate sweep back in the wing design. A special kind of sweep back is the crescent wing. Another, the delta wing, combines a high degree of sweep back with great strength. Sweep back and thin wings bring problems at low speeds, so designers must compromise between high speed and low speed requirements.
- Filing is a way of smoothing and shaping material to exact dimensions. It is used in all branches of engineering, from the finishing of heavy castings to the precision work of the aircraft industry. This training film produced in 1941 demonstrates the basic filing techniques and some of the specialist files used for advanced jobs. It is essential to set up the job properly before starting to file. A vice should be used to hold in place the object to be filed, protecting the object from the jaws of the vice using soft metal clamps. To file correctly, the object must be set up square, with the marking line (showing the limits of filing) facing towards you. It is also important to stand properly before starting to file. Stand with the left foot forward and the right foot back, with the body balanced evenly on both feet. Press the handle of the file firmly into the palm of your right hand, with the thumb on top of the file. Like most other cutting tools, using a file with great force will not add to its cutting power. The teeth can cut away the metal only on the outward stroke, so there should be pressure from the left hand on the return stroke. Since pressure from the left hand clogs the teeth with scurf (surface irregularities or imperfections), the file will lose some of its cutting power. Even without applying pressure some scurf will be picked up, so the file should be cleaned using a wire brush after each job. Check the accuracy of the work frequently. A firm stroke in the direction opposite to the previous filing will reveal any high spots as shaded patches. At a more advanced stage of the job, you can test the surface with a straight edge. If the metal is rubbed in red lead or bluing on a surface plate, the high spots pick up the stain. A dead smooth file, for creating a fine cut made is used for the final stage, known as draw filing, which requires a different grip. When filing the rounded end of a metal fitting, known as a radius, you need to use a circular rolling action. For some jobs, a specially shaped file is needed. These include the thin tapered wearing file, the round rat tailed file, the safe-edge file, and the half round file. Prior to attempting advanced filing techniques individuals should master the three rules of basic filing: correct position, correct grip and correct stroke.

- Although absorbing waste is the river's natural role, discharging it has become an issue following the growth of industry and the modern city. This film explains the function of rivers and explores solutions to issues of river pollution. Water is a universal raw material required in high volumes for industries including steel production and oil refining. After use, it is discarded as waste and discharged to the nearest river to be diluted and absorbed. Transforming polluted water into a safe substance that is free from taste or smell is an elaborate and costly business. Towns and cities use millions of gallons of water a day, some of which travel from lakes and reservoirs that are often far from the centres of industry. Some water is distributed underground, although supplies are often extracted faster than rain can replenish them. Consequently, the same water must be used time and again in order to guarantee a consistent supply. It is essential to understand how a river absorbs waste and why it sometimes fails. In nature, water is never pure, since it collects traces of minerals and organic matter as it trickles over rocks and soil. The activity of micro-organisms, including fungi and bacteria, which feed on oxygen to multiply, keeps the water clean and healthy, providing rivers with the power to dispose of waste matter. As water use increases, more pollution is created, and when it becomes too much for the river to absorb, waste is simply passed on. The bacteria, which feed on waste, multiply at an excessive rate, and the level of oxygen falls dangerously low. If the load of pollution is too heavy, the growth of bacteria becomes overwhelming, exhausting the oxygen supply and devastating the river. Waste is unavoidable, but by treating it before disposing of it, the load on the river can be reduced. Chemical additives and natural methods can be utilised to make toxic waste harmless and remove organic matter, so that it can be safely discharged to the rivers. Although these processes do not provide pure water, they can reduce pollution so that the river can resume its natural role.

- Malaria is a destructive illness, which hinders social and economic progress in the least developed parts of the world and causes millions of fatalities each year. This video describes the characteristics of malaria and explains effective approaches to the prevention of the disease. Malaria is caused by single celled parasites called plasmodium, which live through several stages of development in the blood of humans. Penetrating red blood cells, they travel around the body, moving towards and into the liver cells. The victim, who is weakened with every attack, may feel cold and develop a fever every time the parasites find new red blood cells and multiply. The female mosquito, which feeds on blood to develop its eggs, is responsible for transmitting malaria from person to person. When the insects pierce human skin for access to blood vessels, plasmodium present in the victim passes into the mosquito¨s stomach. It multiplies inside the mosquito and a new generation of parasites travel to the salivary glands so that when the insect bites another victim, plasmodium passes into their bloodstream. Insects and plasmodium multiply rapidly and adapt to their environment, enabling them to survive and multiply. Although drugs can destroy plasmodium, it can only be prevented from being passed between infected people, if the individuals are treated at the same time, otherwise mosquitoes will continue to spread the disease. Mosquitoes can be eradicated using DDT, but in some areas, they have developed resistance to the chemical, causing malaria to spread again. In Africa, where malaria weakens the population and the economy, irrigation systems for crops also provide breeding grounds for mosquitos. Education enables knowledge and support for the local community to understand the nature of the disease. People are encouraged to protect themselves against mosquitoes, whilst hospitals provide drugs, and researchers monitor the mosquito population. The World Health Organisation Malaria Action Programme exists to coordinate knowledge and research, strengthen initiatives in every country and formulate strategies. To make use of this support and keep its people and their environments healthy, each country needs political support, well trained staff and significant economic resources.
- Cornwall, UK, is one of the oldest tin mining areas in the world. In their day, the Cornish pumping engines were the most powerful and economical steam pumps in the world. This documentary charts the history of these giant machines, which were designed and constructed by some of the most talented engineers in the UK. The development of the steam engine dates back to the early 16th century, when miners began to sink shafts into the ground. The first designs were based on the simple principles of the hand pump, but a more powerful engine was needed to pump water on a larger scale. The English engineer and inventor Thomas Savery (c.1650-1715) produced the world's first steam-powered water pump in 1689. His pump consisted of a boiler heated by an open fire. Steam from the boiler entered a condensing chamber. Water sprayed into the chamber condensed the steam, creating a vacuum that could be used to raise water from the mine. Twenty years later, the English blacksmith Thomas Newcomen (1663-1729) developed an improved version of Savery's "atmospheric engine". Newcomen's engine consisted of a cylinder mounted above a boiler. A piston inside the cylinder operated a rod attached to the water pump. The weight of the rod pulled the piston to the top of the cylinder, which then filled with steam from the boiler. When water was sprayed into the cylinder, the steam condensed, creating a vacuum that pulled the piston down to work the pump. In 1763, the experiments of the Scottish engineer James Watt (1736-1819) revealed some fundamental facts about heat energy. His discoveries led him to build a new steam engine, called "Old Bess", in 1776. Watt's engine was used to pump water to drive a water wheel. Watt later developed the first rotary steam engine. This was used for mine winding and mill driving and expanded the use of steam power throughout the world. The rotary steam engine was four times as efficient as the atmospheric engines of Newcomen and Savery. Richard Trevithick (1771-1833), an engineer from Cornwall, was the first person to develop a high pressure steam engine. Built in 1812, the cylindrical Cornish boiler consisted of riveted wrought iron plates and was strong enough to resist steam at extremely high pressures. The Cornish engine was four times as efficient as the Watt's most efficient steam engine. The Cornish engine was erected in London for pumping part of the city's water supply and its use has been adopted in countries as far apart as Australia and Russia.

- Paint has responded to a changing world since its earliest beginnings and now plays a crucial role in protection as well as decoration. This documentary uses archive footage to illustrate the evolution of paint's fabrication and usage from stone age to modern day. 30,000 years ago the first painters used hot animal fat for binding simple earth colours. The paste dried to form a thin waterproof film of colour, which was both decorative and durable. Early civilisations of Mesopotamia used the protective properties of bitumen, a pigment and binding medium in one, to waterproof boats. The Egyptians originated paint technology, creating the first synthetic pigment by fusing together silica, malachite and calcium carbonate at a critical temperature. 12th century monks illustrated books, using linseed oil and varnish, but their sticky, slow-drying properties made fine decorative detail difficult. 15th century Flemish artists perfected the technique of fine painting in oils by using resin tapped from pine trees and distilling it to produce turpentine, a solvent, to thin paint for detailed work. Until the end of the 17th century apothecaries or pharmacists, supplied craftsman with paint making materials but as decoration became more elaborate and sophisticated the demand for paint increased and apothecary shops gave way to oil merchants and distillers. The influence of foreign trade brought new innovations such as gums and resins imported from Africa and India and turpentine derived from the pine forests of North America. The popularity of lacquered wares from China and Japan resulted in the building of factories to produce Far Eastern goods in quantity. Varnish making emerged as an enterprise in its own right, marking the beginnings of the modern paint industry. The industrial revolution saw paint used on a large scale as protection against rust on its great iron structures. Manufacturers experimented with new lead and zinc based paints to combat corrosion and with the onset of mass production, craftsmanship gave way to chemistry. Paint evolved from laboratories and was processed through chemical plants on an industrial scale. Paint is older than the wheel and serves a unique purpose in controlling corrosion and advancing the speeds of mass production. Its manufacture has helped establish a major industry based on science, though its existence is owed to art.
- This documentary follows the design, production and installation of the lantern stained glass in Liverpool Cathedral, and the use of epoxy resin to bond the glass. In the 1960s two new cathedrals were planned for construction in the centre of Liverpool, UK. The first, an Anglican cathedral, was designed in a traditional form. By contrast, the Roman Catholic Cathedral of Christ the King was a strikingly modern design. The architect, Frederick Gibberd, planned the Cathedral of Christ the King as a circular building with a tower made of concrete and stained glass. Two artists, John Piper and Patrick Reyntiens, were commissioned to make the glass. Reyntiens had many years' experience making stained glass following traditional methods. However, the design for the new cathedral called for a new method, using thick glass and reinforced concrete. Collaborating with Piper, Reyntiens decided on a simple design of three great areas of coloured light and a trinity of blue, yellow and red. To achieve their design, the amount of concrete used had to be reduced. The main challenge was to find a material capable of bonding glass to glass and making a joint strong enough to resist even hurricane force winds. After much research, a team of engineers and chemists developed an industrial epoxy resin mix. Strands of fibre glass, coated in epoxy, would be embedded in the bond as reinforcement, in the same way as steel is used to reinforce concrete. The artists then made a full-scale cartoon for each window. The panels, which were 12 feet wide and 1 inch (3.6 metres) thick, were then cast and glazed. The glass was positioned, and the first layer of epoxy resin was squeezed out between them. Finally, the panels were fixed into place. This was the largest commission for stained glass in the history of the Church. This achievement was only accomplished by the joint efforts of the architect, artists, engineers, technologists and craftspeople.
