Gwaith Powdwr
Gwaith Powdwr, (English: ''Powder Works''), situated in Penrhyndeudraeth, Wales, is a decommissioned explosives works now managed as a Nature Reserve by the North Wales Wildlife Trust. The explosives factory was initially opened in 1865 and changed hands several times before being bought by Ralph Cooke in 1922. He renamed the site Cooke's Explosives and the factory became a noted explosives production plant. During the Second World War, it produced more than 17 million grenades. Cooke retired in 1955 and the site was taken over by a partner company, Imperial Chemical Industries, until its closure in 1995. Several accidents occurred at the site, including explosions in 1957 and 1988 which killed six workers in total. Explosives factory The site was opened as the Patent Safety Guncotton Company in 1865 an explosives making factory to provide charges for mining quarries. The factory was officially licensed in 1875 and became part of the New Explosives Company. In the early 20th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powder Works - Geograph
A powder is a dry, bulk solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms ''powder'' and '' granular'' are sometimes used to distinguish separate classes of material. In particular, ''powders'' refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. ''Granulars'' refers to the coarser granular materials that do not tend to form clumps except when wet. Types Many manufactured goods come in powder form, such as flour, sugar, ground coffee, powdered milk, copy machine toner, gunpowder, cosmetic powders, and some pharmaceuticals. In nature, dust, fine sand and snow, volcanic ash, and the top layer of the lunar regolith are also examples. Because of their importance to industry, medicine and earth science, powders have been studied in great detail by chemical engineers, mechanical eng ...

Penrhyndeudraeth
Penrhyndeudraeth (; ) is a small town and community in the Welsh county of Gwynedd. The town is close to the mouth of the River Dwyryd on the A487 nearly east of Porthmadog, and had a population of 2,150 at the 2011 census, increased from 2,031 in 2001. The community includes Minffordd and Portmeirion. History An older settlement of a few cottages at Upper Penrhyn was originally called ''Cefn Coch'' ('Red Ridge') and that name is perpetuated by the Penrhyndeudraeth primary school, which is known as Ysgol Cefn Coch; but the town proper is comparatively modern. The ground on which it stands was a malarial swamp encircling a huge stagnant pool. The present town owes its existence as a commercial centre to a local landowner, David Williams of Castell Deudraeth near Minffordd, who in the mid-19th century drained the swamp and dried the pool and constructed many streets. Adopting a scheme of town planning evolved by the builder of Tremadog and his Italian craftsmen, Williams gave P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperial Chemical Industries
Imperial Chemical Industries (ICI) was a British chemical company. It was, for much of its history, the largest manufacturer in Britain. It was formed by the merger of four leading British chemical companies in 1926. Its headquarters were at Millbank in London. ICI was a constituent of the FT 30 and later the FTSE 100 indices. ICI made general chemicals, plastics, paints, pharmaceuticals and speciality products, including food ingredients, speciality polymers, electronic materials, fragrances and flavourings. In 2008, it was acquired by AkzoNobel, which immediately sold parts of ICI to Henkel and integrated ICI's remaining operations within its existing organisation. History Development of the business (1926–1944) The company was founded in December 1926 from the merger of four companies: Brunner Mond, Nobel Explosives, the United Alkali Company, and British Dyestuffs Corporation. It established its head office at Millbank in London in 1928. Competing with DuPont a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porthmadog
Porthmadog (; ), originally Portmadoc until 1974 and locally as "Port", is a Welsh coastal town and community in the Eifionydd area of Gwynedd and the historic county of Caernarfonshire. It lies east of Criccieth, south-west of Blaenau Ffestiniog, north of Dolgellau and south of Caernarfon. The community population of 4,185 in the 2011 census was put at 4,134 in 2019. It grew in the 19th century as a port for local slate, but as the trade declined, it continued as a shopping and tourism centre, being close to Snowdonia National Park and the Ffestiniog Railway. The 1987 National Eisteddfod was held there. It includes nearby Borth-y-Gest, Morfa Bychan and Tremadog. History Porthmadog came about after William Madocks built a sea wall, the ''Cob'', in 1808–1811 to reclaim much of Traeth Mawr from the sea for farming use. Diversion of the Afon Glaslyn caused it to scour out a new natural harbour deep enough for small ocean-going sailing ships,John Dobson and Roy Woods, ''Ffe ...

Special Area Of Conservation
A Special Area of Conservation (SAC) is defined in the European Union's Habitats Directive (92/43/EEC), also known as the ''Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora''. They are to protect the 220 habitats and approximately 1,000 species listed in annex I and II of the directive which are considered to be of European interest following criteria given in the directive. They must be chosen from the Sites of Community Importance by the member states and designated SAC by an act assuring the conservation measures of the natural habitat. SACs complement Special Protection Areas and together form a network of protected sites across the European Union called Natura 2000. This, in turn, is part of the Emerald network of Areas of Special Conservation Interest (ASCIs) under the Berne Convention. Assessment methodology in the United Kingdom Prior to being designated as a Special Area of Conservation (SAC), sites have been assessed under a two-stage process ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...
