Slawa built the umbrella using existing and modified umbrella parts purchased from manufacturers and other sources with the idea to develop a more practical umbrella. At the time Slawa was a student studying sculpture at the Akademie der Bildenden Kunste Wien (Academy of Visual Arts). She spent many months developing the prototypes in secret before she applied for and received a patent on 19 September 1929. The patent documentation for Flirt noted that although foldable umbrellas with telescopic shafts were not new, the inventor's umbrella was a significant improvement as it was smaller and more practical as the folding mechanism had been considerably simplified. The umbrella was included in the Inventors’ pavilion at the Vienna Spring Fair in 1931. In a contemporary newspaper report it was described as ‘the magic umbrella of the sculptress’. After the design was granted a patent, it was contracted to the firm Basch and Braun, which authorized its manufacture under licence by the largest Austrian umbrella manufacturer in Austria Bruder Wuster and a German firm Kortenbrach und Rauh. It was called Flirt. In the first year of production sales reached 10,000. This number increased steadily each year as sales spread throughout Europe and the Flirt umbrella was still being produced in the post-war period. Slawa was paid royalties till 1938, the year that she left Vienna and fled to Switzerland. In 1939 with pressure from the Nazis she sold her rights to the company Bruder Wuster. Ann Carew 2016The umbrella prototypes have national and international aesthetic significance as examples of technological innovation in industrial design. The archive has national and international scientific and research potential – detailed records concerning the development of the design, patent and its manufacture are held in the studio. The archive demonstrates the links between the realms of fine art, industrial design and manufacturing in Vienna in the early twentieth century. The sale of Slawa Horowitz-Duldig’s rights to the umbrella under duress from the Nazis makes this archive historically significant. The provenance is excellent, and the prototypes and accompanying documentation have national and international interpretative potential. Ann Carew 2016Three handmade compact foldable umbrella prototypes. The prototypes have black silk covers, a metal shaft, handle, ribs and ferrule. The shaft has a telescopic mechanism. The top and the end of the handle are metal disks. The related documents, designs, patent documentation, a hand written record of her inspiration for the design, and other archival material are also held in the Studio’s Collection.

Taking castings from the larynx of cadaver's, Archie Brain studied the anatomy and physiology of the upper airway in minute detail. He devised the Laryngeal Airway Marsk (LMA) as an alternative to endotracheal intubation. Since first gaining a patent in 1982, he produced over 1000 prototypes over the next 30 years in a constant effort to improve the device and patient safety. The LMA is a recent innovation and provides an alternative to endotracheal intubation and has made a significant contribution to safe airway management.

Gustave Auguste Besson and his family manufactured brass musical instruments in France from 1837 and in England from 1857. In England the instruments were stamped "Besson & Co" between 1895 and 1904. The word ‘Prototype’ was stamped on all Besson instruments manufactured after 1885-86 and referred to the method of manufacture. This mouthpiece was found by Warren Bowen in 2017, in the vicinity of the former Linton Railway Station.Metal mouthpiece for a brass musical instrument, probably a cornet or trumpet. Consists of a "U"-shaped cup attached to a tapering shank. "BESSON & Co" and "Prototype" stamped on the shank.brass instruments, musical instruments, besson & co.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement

Worldwide, more than 100 million lambs are castrated, and their tails are docked each year. Numnuts is a technological innovation to improve animal welfare. It combines traditions with innovation. In the mid-1990s it was scientifically shown that the immense pain felt during castration and tail docking could be significantly reduced with the use of anaesthetic. For the next 15 years, the industry said the cost the welfare devices and development were too high. But todays ethical consumer has demanded that sheep have no more pain. Initiated in Glasgow in 2009, Numnuts took nearly a decade to develop. Here you can see five stages of development, from an early prototype to the Numnuts device farmers use today. Each phase of development took years of on-farm trails to achieve the final product. Today there is even NumOcaine, an approved local anaesthetic used by Numnuts. Using the simple elastrator ring and adding an anaesthetic injector, Numnuts delivers pain relief during tail docking and castration. In the world’s first rubber ring applicator with a pain relief delivery mechanism. Through innovation and consumer pressure the wool industry is going through a moment of rapid change.Four prototype numnuts tools made from white plastic and stainless steel, each in varying stages of production.
