Blue Circle Industries

Blue Circle Industries was a British public company manufacturing cement. It was founded in 1900 as the Associated Portland Cement Manufacturers Ltd through the fusion of 24 cement works, mostly located on the Thames and Medway estuaries, together having around a 70% market share of the British cement market. In 1911 the British Portland Cement Manufacturers Ltd. was formed by the addition of a further 35 companies, creating a company with an initial 80% of the British cement market.

Subsequently the company expanded overseas, predominately into commonwealth countries and South and Central America. The energy crisis of the 1970 caused the contraction of the company, and the sale of its overseas plants. In 1978 the company officially changed its name to Blue Circle.

In 2001 the company was bought by Lafarge.

History

Circle

A circle is a simple shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.

A circle is a simple closed curve which divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a disk.

A circle may also be defined as a special ellipse in which the two foci are coincident and the eccentricity is 0, or the two-dimensional shape enclosing the most area per unit perimeter squared, using calculus of variations.

Terminology

Red Circle

Red Circle may refer to:

Blue

Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while those with a lower frequency and a longer wavelength gradually appear more green. Pure blue, in the middle, has a wavelength of 470 nanometres. In painting and traditional colour theory, blue is one of the three primary colours of pigments, along with red and yellow, which can be mixed to form a wide gamut of colours. Red and blue mixed together form violet, blue and yellow together form green. Blue is also a primary colour in the RGB colour model, used to create all the colours on the screen of a television or computer monitor.

The modern English word blue comes from Middle English bleu or blewe, from the Old French bleu, a word of Germanic origin, related to the Old High German word blao. The clear sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes. Rayleigh scattering also explains blue eyes; there is no blue pigment in blue eyes. Distant objects appear more blue because of another optical effect called atmospheric perspective.

The Battlefield (1985 TV series)

The Battlefield is a Hong Kong television series loosely based on the events in the Chu–Han Contention, an interregnum between the fall of the Qin dynasty and the founding of the Han dynasty. It was first broadcast in 1985 in Hong Kong on TVB Jade.

Plot

Two heroes emerged in the final years of the Qin dynasty. They are Lau Bong and Hung Yu. Both of them were initially close friends, but later became rivals in a power struggle for supremacy over China historically known as the Chu–Han Contention.

Hon Sun meets Cheung Leung by coincidence and they strike up a friendship. Hon Sun remains on Hung Yu's side while Cheung Leung decides to serve Lau Bong. Not long later, Hon Sun leaves Hung Yu and is introduced to Lau Bong by Siu Ho. Hon Sun and Cheung Leung work together to help Lau Bong achieve his dream of ruling China.

Yuk Dip-yee is a former imperial spy who was sent to assassinate Hung Yu. However, she falls in love with Hung Yu and is unable to bring herself to kill him. She eventually dies at the hands of Hung Yu's uncle, Hung Leung. Subsequently, a beauty called Consort Yu appears and becomes the subject of a love rivalry between Hung Yu and Lau Bong. Hung Yu eventually wins Consort Yu's heart. In anger, Lau Bong marries Lui Chi, intending to use her father to help him deal with Hung Yu. This marks the beginning of the war between Lau Bong and Hung Yu.
