1910 – "The Black & Decker Manufacturing Company" was founded by S. Duncan Black (1883–1951) and Alonzo G. Decker (1884–1956) as a small machine shop in Baltimore in September. Decker, who had only a seventh grade education, had met Black in 1906, when they were both 23-year-old workers at the Rowland Telegraph Company.
Black & Decker had trouble keeping up with demand for the Workmate in the UK, but was still unconvinced of how well the Workmate would be accepted in the United States. As a test of demand, the UK-manufactured Workmate WM325 was introduced to the United States market in 1974 as the Model 79-001 Type E ("E" for England).
In piston engines, water can accumulate in the cylinders and cause a hydraulic lock which will damage the engine; In thermal power stations, water droplets in high velocity steam coming from nozzles (or vanes) in a steam turbine can impinge on and erode turbine internals such as turbine blades.
In 2012, Hasbro announced the premiere of a version of the Easy-Bake Oven in black and silver after executives met with McKenna Pope, a girl from Garfield, New Jersey, who had started a Change.org petition asking the toy maker to offer the product in gender-neutral packaging. [26] [27] The prototype Easy-Bake Oven was also made available in ...
An American Dutch oven, 1896. A Dutch oven, Dutch pot (US English), or casserole dish (international) is a thick-walled cooking pot with a tight-fitting lid. Dutch ovens are usually made of seasoned cast iron; however, some Dutch ovens are instead made of cast aluminium, or ceramic.
The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
Direct reduction processes can be divided roughly into two categories: gas-based and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.) in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
Water removal is the primary means of weight and volume reduction, while pathogen destruction is frequently accomplished through heating during thermophilic digestion, composting, or incineration. The choice of a sludge treatment method depends on the volume of sludge generated, and comparison of treatment costs required for available disposal ...
