A wind sock or wind cone is a conical textile pipe that looks like a giant sock. Wind hoses can be used as a basic guide for wind direction and speed. In most cases, the ideal place to buy a wind sock or a complete installation is an international specialist. Holland Aviation, for example, is an expert in the manufacture and international supply of windhoses and installations. In this way, you can always count on a quality product manufactured according to the general rules and regulations. Check out our selection of wind socks to find a right wind sleeve for your own needs. New wind socks are produced in accordance with ICAO guidelines. This means that all current models are calibrated to fully inflate to wind speeds of 15 knots or more. But a green wind sleeve is very useful near a nature reserve where a red/white sock is not always allowed. Near such places, a green wind sleeve is a perfect solution. ICAO standards require a cone-shaped handle stump with a length of at least 3.6 m and a diameter of 0.9 m at the large end. It must be visible and understandable from a height of 300 m and ideally monochrome.
If it is necessary to use two colors, they should ideally be orange and white, arranged in five alternating stripes, the first and last being darker. At winds of 3 knots (5.6 km/h; 3.5 mph) or more, they must indicate the wind direction below ±5°.  By now, you should be a true wind sock expert! Do you have any questions?

The first source of instruction is an extract from the report of the labour inspector for 1836, three years after the adoption of the old Factories Act. The second source is an 1867 report. Students can use both to assess the effectiveness of the 1833 Act. Students look at two other visual sources. It is important to evaluate them based on their data and the content they represent. The 1903 photo is interesting evidence. What does this reveal about working conditions and safety in the factory? The picture mentioned at the beginning of the lesson of an «double room» from 1851 shows only female workers.
What for? Note that doubling meant that the wire was «doubled» after spinning to increase its thickness. The drawing is an artistic representation, how realistic is the scene? Overall, students should be encouraged to reflect on the reliability of this evidence in order to assess the success of such factory legislation. What other sources could help us understand its effectiveness? Finally, talk with students about other industries associated with child labour in the Victorian era. However, not all factory owners have kept their workers in poor conditions. Robert Owen, who owned a cotton mill in Lanark, Scotland, built the village of New Lanark for his workers. Here they had access to schools, doctors and there was a home for every family who worked in its factories. People began to realize how bad these conditions were in many factories and began to push for improvements. There was a lot of resistance from factory owners who felt that it would slow down the operation of their factories and make their products more expensive. Many people also didn`t like the government interfering in their lives. For example, some parents needed their children to go to work at an early age because they needed money to feed the family.
A wind sleeve as we know it today is a conical tube made of woven textile that measures both wind direction and speed. Possible activities: Use these sources to write a campaign letter against child factory labour in 1833; Create a poster for such a campaign. Highly visible alternating bands of orange and white were first used to estimate wind speed, with each band increasing the estimated speed by 3 knots. However, some circular frame supports keep the wind sleeves open at one end, indicating a speed of 3 knots even if it is not present. A fully extended wind sleeve indicates a wind speed of 15 knots (28 km/h; 17 mph) or more.  A wind sleeve (also called a wind cone) is a conical textile tube that looks like a giant sock. It can be used as a basic indicator of wind speed and direction, or as a decoration. They are typically used in airports to show pilots the direction and strength of the wind, and in chemical plants where there is a risk of gas leakage. They are also sometimes located along highways in windy places. The stripes of a wind sleeve are not only chosen to be visible from far away. If a tape is «swollen» by the wind, you can use it to read the current wind speed.
In many airports, the wind sleeves are illuminated outside or indoors at night.  www.parliament.uk/about/living-heritage/transformingsociety/livinglearning/19thcentury/overview/factoryact/ An overview of the 1833 Factories Act and 10 Hours of Movement In many airports, the wind sleeves are illuminated at night, either by spotlights that surround them or by a pole-mounted searchlight. They are mounted on a special installation. These usually consist of a metal mast made of aluminum or galvanized steel. The mast is placed on a metal foundation to withstand high wind speeds. On the mast there is a metal basket (or swivel frame), which can be rotated horizontally by 180 degrees. The wind sleeve is attached to it so that it can move freely depending on the origin of the wind. The red and white striped version is the most famous version you`ll often see along the road. Nevertheless, many different colors are used internationally, such as orange (striped), green, blue and completely orange. In general, the colors are chosen in such a way that the entire installation is clearly visible in relation to the background. In the maritime world, almost no blue wind sock is used. But at airports, where there`s a lot of grass around the runway, green socks are barely used.
