James Thomas Engineering
James Thomas Engineering (JTE) is a British manufacturing company based in Worcester, Worcestershire. From 1990, the company also has offices in Knoxville, Tennessee. The company manufactures stage lighting equipment and stage rigging equipment, such as trusses, PAR lamp enclosures and more recently LED stage lighting equipment. History James Thomas Engineering was formed in February 1977 in a small garage in Bishampton, England by James Thomas and John Walters, manufacturing spun aluminium par lanterns. In 1978 it moved to Pershore and started manufacturing truss. It developed a pre-rigged truss system in 1983 and relocated to larger premises in Pershore in 1984. In 1990 JTE opened a USA office for manufacturing truss. In July 2000 the UK office relocated again to a larger 52,700 square foot facility in Worcester and in October 2001 the USA site relocated to a 30,000 square foot facility. In 2002 the company started manufacturing LED stage lighting fixtures as part o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entertainment Rigging
Rigging in entertainment can be broken down into two main subjects – theatrical rigging and arena-style rigging. All the same skills apply in both genres. The first takes place in a theatre, and typically involves the theatre's permanent fly system. The other in an arena or "exposed structure venue" such as a convention center, ballroom, warehouse etc. Circus rigging, comprising aerial acrobatic apparatuses that support human beings under dynamic loading conditions, and stabilization rigging for large scale fabric tension structures (big tops), is, perhaps, under appreciated in the general rigging field, and may be considered by some to be a separate field. However, the principles of physics and the standards of engineering that apply to theatrical and arena rigging still hold true in circus rigging, and much of the same equipment and many of the same devices are commonly used. All the same skills apply in this genre as well. Chain motors and trusses are not used as often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PAR Lamp
A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam. Usage includes theatrical lighting, locomotive headlamps, aircraft landing lights, and residential and commercial recessed lights ("cans" in the United States). Many PAR lamps are of the sealed beam variety, with a parabolic reflector, one or more filaments, and a glass or plastic lens sealed permanently together as a unit. Originally introduced for road vehicle headlamp service, sealed beams have since been applied elsewhere. Halogen sealed beam lamps incorporate a halogen lamp within a quartz or hard glass envelope. Construction A PAR lamp consists of a light source, with lens and a parabolic reflector with a smooth aluminium surface determining the spread of the beam. The most common sealed beam type combines these three elements into an integral unit. The light s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics Companies Of The United Kingdom
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small elect ...

Indiana State Fair Stage Collapse
The Indiana State Fair stage collapse was an incident during an August 13, 2011, outdoor concert by Sugarland as part of their Incredible Machine Tour at the Indiana State Fair in which a wind gust from an approaching severe thunderstorm hit the stage's temporary roof structure, causing it to collapse. The structure landed among a crowd of spectators, killing seven people and injuring 58 others. The members of Sugarland were in a tour bus preparing to come on stage when the collapse occurred at 8:46 p.m. Opening act Sara Bareilles had completed her performance prior to the incident. Events leading up to the collapse Discussions about delaying the show Throughout the day and evening of the concert, the National Weather Service issued notices and warnings predicting strong thunderstorms. Messages about the forecasts were relayed to various State Fair personnel via an automated text-messaging system.Witt Associates''An Independent Assessment of the August 13, 2011 Indiana ...

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments ( torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary f ...

Pershore
Pershore is a market town in the Wychavon district in Worcestershire, England, on the banks of the River Avon. The town is part of the West Worcestershire parliamentary constituency. At the 2011 census, the population was 7,125. The town is best known for Pershore Abbey, Pershore College (now a campus of Warwickshire College) and plums grown locally. Pershore is situated on the River Avon, west of Evesham and east of Upton-upon-Severn in the Vale of Evesham, a district rich in fruit and vegetable production. History The town contains much elegant Georgian architecture. In 1964 the Council for British Archaeology included Pershore in its list of 51 British "Gem Towns" worthy of special consideration for historic preservation, and it has been listed as an outstanding conservation area. Parts of the abbey, which stand in an expanse of public grassland close to the centre of the town, date from the 11th century. The current structure is far smaller than the original b ...

Aluminium
Aluminium (aluminum in AmE, American and CanE, Canadian English) is a chemical element with the Symbol (chemistry), symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and Passivation (chemistry), forms a protective layer of Aluminium oxide, oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, Magnetism, non-magnetic and ductility, ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of Aluminum-26, 26Al is used in Radiometric dating, radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LED Stage Lighting
LED stage lighting instruments are stage lighting instruments that use light-emitting diodes (LEDs) as a light source. LED instruments are an alternative to traditional stage lighting instruments which use halogen lamp or high-intensity discharge lamps. Like other LED instruments, they have high light output with lower power consumption. Types LED stage lights come in three main types. PAR cans, striplights and ' moving head' types. In LED PAR cans, a round printed circuit board with LEDs mounted on is used in place of a PAR lamp. Moving head types can either be a bank of LEDs mounted on a yoke or more conventional moving head lights with the bulb replaced with an LED bank. In fact, there is no such thing as an LED PAR can - it is a misnomer possibly attributed to Chinese manufacturers. As there is no Parabolic Aluminised Reflector in an LED 'PAR', they would be more accurately referred to as to as 'LED flood lights'. Many LED fixtures are now made using a small number of high- ...

Worcestershire
Worcestershire ( , ; written abbreviation: Worcs) is a county in the West Midlands of England. The area that is now Worcestershire was absorbed into the unified Kingdom of England in 927, at which time it was constituted as a county (see History of Worcestershire). Over the centuries the county borders have been modified, but it was not until 1844 that substantial changes were made. Worcestershire was abolished as part of local government reforms in 1974, with its northern area becoming part of the West Midlands and the rest part of the county of Hereford and Worcester. In 1998 the county of Hereford and Worcester was abolished and Worcestershire was reconstituted, again without the West Midlands area. Location The county borders Herefordshire to the west, Shropshire to the north-west, Staffordshire only just to the north, West Midlands to the north and north-east, Warwickshire to the east and Gloucestershire to the south.
