Air Lock Diving-bell Plant
Port of Gibraltar, Gibraltar Harbour's air lock diving-bell plant, or caisson diving bell barge, was a purpose-built barge for the laying, examination and repair of moorings for battleships. It was designed by Siebe Gorman, Siebe Gorman & Company of Lambeth and Forrestt & Co. Ltd of Wivenhoe in Essex, who built and supplied it in 1902 for the British Admiralty. Local conditions at Gibraltar dictated the need for such a craft. The heavy harbour moorings have three chains extending out radially along the seabed from a central ring, each terminating in a large anchor. Most harbours have a soft seabed, and it is usual to lay down moorings by settling anchors in the mud, clay or sand, but this could not be done in Gibraltar harbour where the seabed is hard rock. For Gibraltar the seabed needed to be dug out sufficiently for an anchor point to hold. The barge would be towed over the work site, moored in place with anchors, and the bell would be lowered to the seabed. Air pumped into th ...

The Times History Of The War (1914) (14577627960)
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'') ...

Jackhammer
A jackhammer (pneumatic drill or demolition hammer in British English) is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. It was invented by William McReavy, who then sold the patent to Charles Brady King. Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete. A jackhammer operates by driving an ''internal'' hammer up and down. The hammer is first driven down to strike the chisel and then back up to return the hammer to the original position to repeat the cycle. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. It is generally used like a hammer to break the hard surface or rock in construction works and it is not considered under earth-moving equipment, al ...

Davis breathing set was destined to allow British submarine crews to escape when their ship started to sink. While still directing Siebe Gorman Davis was the first British to buy a licence from the Cousteau- Gagnan Aqua-Lung (from the French company La Spirotechnique), starting commercialization of scuba sets in Britain as of 1948.

Lofting
Lofting is a Technical drawing, drafting technique to generate curved lines. It is used in plans for streamlined objects such as aircraft and boats. The lines may be drawn on wood and the wood then cut for advanced woodworking. The technique can be as simple as bending a flexible object, such as a long strip of thin wood or thin plastic, so that it passes over three non-linear points, and scribing the resultant curved line; or as elaborate as plotting the line using computers or mathematical tables. Lofting is particularly useful in boat building, when it is used to draw and cut pieces for hull (watercraft), hulls and keels. These are usually curved, often in three dimensions. Loftsmen at the mould lofts of shipyards were responsible for taking the dimensions and details from drawings and plans, and translating this information into templates, Batten, battens, Abscissa and ordinate, ordinates, cutting sketches, profiles, margins and other data. From the early 1970s onward compute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
