Ballbarrow
The Ballbarrow was a variation of the wheelbarrow design, by James Dyson and was released in 1974 in the UK. It featured a moulded plastic hopper on a steel frame and a spherical plastic wheel, allowing increased manoeuvrability. Dyson said that the surface area of the ball, larger than that of a conventional design, made the wheelbarrow easier to use in soft soil and more laterally stable with heavy loads on uneven ground. The original design featured a galvanised steel or copper hopper, forming integral rear legs. Conventional barrows use a bend in the frame to form these legs. Later the design was changed to a plastic hopper, with an optional clip on height-extension piece. The Ballbarrow won the Building Design Innovation Award A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and funct .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wheelbarrow
A wheelbarrow is a small hand-propelled vehicle, usually with just one wheel, designed to be pushed and guided by a single person using two handles at the rear, or by a sail to push the ancient wheelbarrow by wind. The term "wheelbarrow" is made of two words: "wheel" and "barrow." "Barrow" is a derivation of the Old English "barew" which was a device used for carrying loads. The wheelbarrow is designed to distribute the weight of its load between the wheel and the operator, so enabling the convenient carriage of heavier and bulkier loads than would be possible were the weight carried entirely by the operator. As such it is a second-class lever. Traditional Chinese wheelbarrows, however, had a central wheel supporting the whole load. Use of wheelbarrows is common in the construction industry and in gardening. Typical capacity is approximately of material. A two-wheel type is more stable on level ground, while the almost universal one-wheel type has better maneuverability in s ...

James Dyson
Sir James Dyson (born 2 May 1947) is a British inventor, industrial designer, farmer, and billionaire entrepreneur who founded Dyson Ltd. He is best known as the inventor of the dual cyclone bagless vacuum cleaner, which works on the principle of cyclonic separation. According to the ''Sunday Times'' Rich List 2022, he is the second richest person in the UK with an estimated net worth of £23 billion. He served as the Provost of the Royal College of Art from August 2011 to July 2017, and opened a new university, the Dyson Institute of Engineering and Technology, on Dyson's Wiltshire campus in September 2017. Early life and education James Dyson was born 2 May 1947 in Cromer, Norfolk, one of three children, and named after his grandfather, James Dyson. He was educated at Gresham's School, an independent boarding school in Holt, Norfolk, from 1956 to 1965, when his father died of prostate cancer. He excelled at long-distance running: "I was quite good at it, not because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Dyson Products
Dyson is a Singapore-based company and manufacturer of bagless vacuum cleaners (using cyclonic separation and brushless electric motors), heatless hand dryers, bladeless fans/heaters, and robotic vacuum cleaners. Technologies Dyson has developed various basic technologies for use in their products, including designing and manufacturing its own specialized motors. Dyson Digital Motor The electric motor marketed as the Dyson Digital Motor (DDM) is a direct current motor, operating on the switched reluctance principle. These brushless motors rotate at up to 110,000 rpm. The motor used a two-pole brushless rotor with a digital controller. Dyson said its efficiency was 84%, which was less than the 96% efficiency that is achieved in some brushless designs. In order to deal with the high speed and centrifugal forces, the impeller is made of carbon fibre reinforced polymer; the shaft is steel. The first mass-produced version was named "X020" and used in the Airblade hand dryer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The journal became an outlet for writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Design Innovation Award
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English Inventions
English inventions and discoveries are objects, processes or techniques invented, innovated or discovered, partially or entirely, in England by a person from England. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two. Nonetheless, science and technology in England continued to develop rapidly in absolute terms. Furthermore, according to a Japanese research firm, over 40% of the world's inventions and discoveries were made in the UK, followed by France with 24% of the world's inventions and discoveries made in France and followed by the US with 20%. The following is a list of inventions, innovations or discoveries known or generally recognised to be English.
