New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Bungy
Bungee jumping (), also spelled bungy jumping, is an activity that involves a person jumping from a great height while connected to a large elastic cord. The launching pad is usually erected on a tall structure such as a building or crane, a bridge across a deep ravine, or on a natural geographic feature such as a cliff. It is also possible to jump from a type of aircraft that has the ability to hover above the ground, such as a hot-air-balloon or helicopter. The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the kinetic energy is dissipated. Early tethered jumping The land diving ( Sa: ') of Pentecost Island in Vanuatu is an ancient ritual in which young men jump from tall wooden platforms with vines tied to their ankles as a test of their courage and passage into manhood. Unlike in modern bungee-jumping, land-d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Topdressing
Aerial topdressing is the aerial application of fertilisers over farmland using agricultural aircraft. It was developed in New Zealand in the 1940s and rapidly adopted elsewhere in the 1950s. Origins Previous aerial applications The first known aerial application of agricultural materials was by John Chaytor, who spread seed over a swamped valley floor in Wairoa, New Zealand, in 1906 using a hot air balloon with mobile tethers. The first known use of a heavier-than-air machine in aerial application was on 3 August 1921 when, as a result of advocacy by Dr Coad, a USAAC Curtiss JN4 Jenny piloted by John A. Macready was used to spread lead arsenate to kill catalpa sphinx caterpillars near Troy, Ohio, United States. The first commercial operations were attempted in the US in 1924 and use of insecticide and fungicide for crop dusting slowly spread in the Americas and, to a lesser extent, other nations. Crop dusting poisons enjoyed a boom in the US and Europe after World War II ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alan Prichard
Alan Marcus Prichard (15 November 1907 – 2 November 1986) was a pilot for the New Zealand Public Works Department from the late 1930s to mid-1950s. Using a Miles Whitney Straight from 1939 on his own initiative and sometimes forging aircraft log books to conceal his work, Prichard conducted trials of aerial seed sowing and spreading fertilizer which ultimately led to the development of aerial topdressing Aerial topdressing is the aerial application of fertilisers over farmland using agricultural aircraft.

Bill Pickering (rocket Scientist)
William Hayward Pickering (24 December 1910 – 15 March 2004) was a New Zealand-born aerospace engineer who headed Pasadena, California's Jet Propulsion Laboratory (JPL) for 22 years, retiring in 1976. He was a senior NASA luminary and pioneered the exploration of space. Pickering was also a founding member of the United States National Academy of Engineering. Origins and education Born in Wellington, New Zealand, on 24 December 1910, Pickering attended Havelock School, Marlborough, and Wellington College. After spending a year at the Canterbury University College, he moved to the United States (where he subsequently naturalized), to complete a bachelor's degree at the California Institute of Technology ("Caltech"), and later, in 1936, a PhD in Physics. His speciality was in Electrical Engineering, and he majored in what is now commonly known in scientific vernacular as 'telemetry'.

Richard Pearse
Richard William Pearse (3 December 187729 July 1953) was a New Zealand farmer and inventor who performed pioneering aviation experiments. Witnesses interviewed many years afterward describe observing Pearse flying and landing a powered heavier-than-air machine on 31 March 1903, nine months before the Wright brothers flew. Ambiguous statements made by Pearse himself make it difficult to date the aviation experiments with certainty. In a newspaper interview in 1909, with respect to inventing a flying machine, he said "I did not attempt anything practical with the idea until 1904". Biographer Gordon Ogilvie credits Pearse with "several far-sighted concepts: a monoplane configuration, wing flaps and rear elevator, tricycle undercarriage with steerable nosewheel, and a propeller with variable-pitch blades." Pearse largely ended his early flying experiments about 1911 but pioneered on in novel aircraft and aero-engine invention from 1933 with the development of his "private plane ...

Tranquilliser Gun
A dart gun is an air rifle that fires a dart. The dart is tipped with a hypodermic needle and filled with a tranquilizer, vaccine, or antibiotic. A dart gun containing a tranquillizer is called a tranquillizer gun ( also spelled tranquilizer, tranquilliser or tranquiliser). History The modern dart gun was invented in the 1950s by New Zealander Colin Murdoch. While working with colleagues to study populations of deer and wild goats introduced to New Zealand, he considered that the animals would be easier to catch, examine, and release if a dose of tranquillizer could be administered by projection from afar. To that end, Murdoch went on to develop a range of rifles, darts, and pistols. The first modern remote drug-delivery system was invented by scientists at the University of Georgia in the 1950s, and was the direct predecessor to the Cap-Chur equipment used worldwide for decades. In the early 1960s, a team in Kenya headed by Drs. Tony Pooley and Toni Harthoorn discovered that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disposable Syringe
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids. There are also prefilled syringes (disposable syringes marketed with liquid inside). The word "syringe" is derived from the Greek σύριγξ (''syrinx'', meaning "Pan flute", "tube"). Medical syringes Sectors in the syringe and needle market include disposable and safety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colin Murdoch
Colin Albert Murdoch (6 February 1929 – 4 May 2008) was a New Zealand pharmacist and veterinarian who made a number of significant inventions, in particular the tranquilliser gun, the disposable hypodermic syringe and the child-proof medicine container. He had a total of 46 patents registered in his name. Biographical background Born in Christchurch, New Zealand, in 1929, to parents Mary Kathleen and Frank William James, Murdoch displayed a talent for chemistry at a very early age. Although he struggled through his schooling years with dyslexia, Murdoch already displayed an interest in both mechanical and technical skills. At the age of ten he successfully made gunpowder and came to the realization that an ignition could be caused by the mixing of certain nitrates and sulphuric acid. This discovery led the young Murdoch to build a successful firearm using a wick and a small asbestos-filled hammer. At the age of 13 he was awarded the Royal Humane Society Medal ...

Portable Sawmill
Portable sawmills are sawmills small enough to be moved easily and set up in the field. They have existed for over 100 years but grew in popularity in the United States starting in the 1970s, when the 1973 oil crisis and the back-to-the-land movement had led to renewed interest in small woodlots and in self-sufficiency. Their popularity has grown exponentially since 1982, when the portable bandsaw mill was first commercialized. History Arguably, as once used in early Canadian forest logging, the donkey engine was one of the earliest portable sawmills. It was used to winch and haul log booms across lakes and water, then winch itself across land or water to its next site, and finally it would be reconfigured to run a saw to mill the timber. The first dedicated portable sawmills were typified by the "One Man Farmer's Sawmills" that featured large circular blades and were marketed during the early twentieth century by companies like Sears, Montgomery Ward and JC Penney.

Peter Lynn
Peter Lynn (born 1946) is a New Zealand kitemaker, engineer and inventor. He is notable for his construction of the world's largest kites (Guinness book of records holders), giant inflatable (sparless) display kites (the most widely known is the 27 m octopus kite), the popularisation of kite buggying and contributions to the development of power kiting and kitesurfing. He spends much of the year travelling worldwide and displaying his kites at International Kite Festivals. Lynn, together with his wife Elwyn, established a kite business at Ashburton, New Zealand, in 1971, producing single-line kites for children. In 1974 he developed the Peter Lynn Triangular box kite, a framed triangular form cellular single line kite. Beginning in 1984 with the Centipede design, he then developed large creature-themed display kites for the growing number of international kite festivals. These large-scale sparless kites include the manta ray, octopus, puffer-fish, gecko and trilobit In 1987 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chipseal
Chipseal (also chip seal or chip and seal) is a pavement surface treatment that combines one or more layer(s) of asphalt with one or more layer(s) of fine aggregate. In the United States, chipseals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as asphaltic surface treatment. This type of surface has a variety of other names including tar-seal or tarseal, tar and chip, sprayed seal or surface dressing. In Australia as well as New Zealand, chipseal roads are common, including usage on major highways Uses Chipsealing is cheaper than resurfacing an asphalt concrete or a Portland cement concrete pavement, but not as long-lasting. Installation Chipseals are constructed by evenly distributing a thin base of hot tar, bitumen or asphalt onto an existing pavement and then embedding finely graded aggregate into it. The aggregate is evenly distributed over the hot seal spray, then rolled into the bitumen using heavy rubber tired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
