... track that ran upwind of the target." "Air resistance acting... track that ran upwind of the target." "Air resistance acting ...Purpose built mechanical calculation machine for determining the drift of aircraft when operating in crosswind conditions. This device has an eyepiece and a prismatic periscope for viewing a distant feature being tracked. This device has calibrated rotary scales for height, speed (in KNOTS and MPH), and an adjustment to preset the 'crab angle' of the aircaft for cross wind compensation. The device can be opened for cleaning or maintenance purposes. Refer to the following extracts for information about bomb drift: "Crosswinds brought into the bombing problem a new factor, "drift" In order to fly a given ground track in a crosswind, an aircraft had to "crab" into the wind; the angle formed between the aircraft's true heading and its ground track was called the "drift angle" In a crosswind, the bomb would impact directly behind the aircraft and along its longitudinal axis at the moment of release. But this meant that the bomb would strike the ground at some point downwind of the aircraft's ground track. Thus, in order to score a hit, the bomber had to fly a ground track that ran upwind of the target." "Air resistance acting on a bomb after release caused it to lag behind the drop point and hit somewhere behind the bomber. The distance from a point beneath the aircraft at the instant of bomb impact to the point of bomb impact was called "trail." Trail increased as the bomber's airspeed increased or as its altitude increased. Furthermore, since different bombs encountered different resistance in the air, trail was also a factor of bomb shape."A. M. Drift Recorder MKII REF. No 6B/190 No 2668/41 X/ 3606 3E4H28 -

Equipment - Stevenson Screen, Thomas Stevenson, ca. 1910
Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

Plan - Ship Plan, Orient Steam Navigation Company, Orient Line, RMS Orion, ca. 1934
The Orient Steam Navigation Company Limited launched the Ocean Liner RMS Orion in 1934 and it remained in operation until 1963. The twin screw steamship was built to carry first class and tourist class passengers, over 1100 in all, plus almost 500 crew from Europe to Australia in comfort. The ship had a single funnel and a single mast. During WWII the vessel served as a troop carrier. The ventilation system noted on the plan, Punkah Louvre System, was designed for heating fresh air ventilation in buildings, ships and railroads. The system originated from Thermotank in Glasgow, Scotland. The ship plan for the RMS Orion is significant for its connection with the vessel. The ship was a leader, with several 'firsts'; the first Orient Line ship to be built with a single funnel since 1902, and the first to be painted in the Orient Line's livery, with a corn-coloured hull. It was the first liner to use chromium and bakelite materials for the surfaces throughout the ship, which provided greater resistance to the sea. It was also the first British ship to be fitted with air conditioning.Plan: printed provisional line drawing of the Orient line vessel "R.M.S. Orion". Inscriptions are printed on the plan. There are diagrams of six decks included in the plan. The ship is built for tourist "B" accommodation. The plan's Notices include details of the cabins including wardrobes, drawers, hinged seats, mattresses and bunk numbers. It also notes that there is a Punkah-Louvre System of Ventilation.Printed on the plan: "PROVISIONAL PLAN" "LOWER PROMENADE DECK" "UPPER CABIN DECK" "MAIN CABIN DECK" "LOWER CABIN DECK" "SUN DECK" "PROMENADE DECK" "ORIENT LINE / R.M.S.

Equipment - Protective metal dust mask associated with Dr Lorna Lloyd-Green
This style of mask was developed in Britain and began to appear from the 1930s, though original models may have been produced in the 1920s. Various patents for this style of mask were still being filed in the 1960s, so they were used for a considerable period of time. It is possible that the original filter pads for these masks contained asbestos, as they supposedly utilised 'fire proof' materials. Asbestos was already in use in other British respirator masks at this time. Original cataloguing information believed this item to be an eye shield, but further research has indicated that this is not the case.Mask consists of a metal plate designed to cover the lower half of the face. There is a recess along the top edge of the plate designed for the nose to sit in. There is a large oblong opening with rounded corners at the centre of the mask, which is a mouth opening to assist speech and is the main air intake. There are five round holes on either side of the mask, likely included to decrease the mask's breathing resistance for the wearer. Rounded slots at each edge of the mask are threaded through with an elastic strap, used for attaching the mask to the face. This mask would have been used with a filtering pad attached, but the pad is missing.
