A bonded seal commonly seals between bolt head and body. In mechanical engineering, a bonded seal is a type of washer used to provide a seal around a screw or bolt. Originally made by Dowty Group, they are also known as Dowty seals or Dowty washers. [1] Now widely manufactured, they are available in a range of standard sizes and materials [2 ...
In 1945, Dowty Seals was founded; during 1950, another new entity, Dowty Hydraulic Units, was created, while Dowty Fuel Systems followed in 1953. Various businesses were also acquired by the growing company, including New Mendip Engineering in 1948 and Coventry Precision in 1951. [4]
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
The company can be traced to the establishment of a 50/50 joint venture in 1995 between France's Messier and the United Kingdom's Dowty Group, then owned by TI Group. Messier-Dowty was purchased outright from TI Group by the SNECMA group in 1998. The 2005 merger of SAGEM and SNECMA made Messier-Dowty part of the new Safran company.
One of four 6-bladed Dowty Rotol R391 composite controllable- and reversible-pitch propellers on the Lockheed Martin C-130J Super Hercules. The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, [1] the market being too small to support more than one company.
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
In 1931 he set up his own company in Cheltenham making aircraft equipment: for this purpose he leased a factory and bought Arle Court in Cheltenham. [1] Dowty invented the first internally sprung aircraft wheel (used on the Gloster Gladiator) [1] and by the time World War II had broken out the company was known as Dowty Aviation and was making the hydraulic systems in planes in Britain, Canada ...
