Tideland Signal
Tideland Signal, sometimes referred to as Tidelands, was a privately held, Houston, Texas based manufacturer of marine navigational aids, with main offices in Lafayette, Louisiana, Vancouver, British Columbia, Canada, Burgess Hill, UK, Dubai, United Arab Emirates and Singapore. It was the manufacturer of the ML-300 lantern, widely used in lighthouses around the world for more than 50 years. In 2016, Tideland was acquired by Xylem. In 2020 it ceased operations. History Tideland Signal was founded by several salesmen of Automatic Power, a battery manufacturer which was then a primary player in the buoy market. The company originally sold directly to Automatic's market, but with limited success. During the 1960s, solar cells had started to become practical systems for recharging batteries in remote locations. Hoffman Electronics, a pioneer in solar power, had approached Automatic with the idea of placing panels on their buoys to reduce the number of battery replacements needed to k ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ''Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and service ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The '' catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturing Companies Established In 1954
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. ...

Buoy
A buoy () is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. Types Navigational buoys * Race course marker buoys are used for buoy racing, the most prevalent form of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are also used in underwater orienteering competitions. * Emergency wreck buoys provide a clear and unambiguous means of temporarily marking new wrecks, typically for the first 24–72 hours. They are coloured in an equal number of blue and yellow vertical stripes and fitted with an alternating blue and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the . * Ice marking buoys mark holes in frozen lakes and rivers so snowmobiles do not drive over the holes. * Large Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped wi ...

Dent Island Light
Dent Island Light is an active lighthouse on Dent Island (Queensland), Dent Island, a small island off the coast of Queensland, Australia, part of the Whitsunday Group of the Whitsunday Islands. Located on the southwest tip of the island, the light guides ships navigating the Whitsunday Passage, between Whitsunday Island and the islands to the west, and marks the Dent Island Passage. From its inception, the lighthouse was closely connected to Cape Cleveland Light. Both lighthouses were recommended, approved, tendered and finally, in December 1879, constructed together. The light had two upgrades in the 1920s, replacing both the oil lamp and fourth-order lens with an incandescent gas mantle and a new lens. In 1983, it was converted to solar power; and was demanned in 1987. The lighthouse is a typical for Queensland, made of a timber frame cladding (construction), clad with galvanized iron plates. It is topped by a Chance Brothers lantern room, and painted white with a red dome. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
