orphan date June 2010 The en US spelling ...analyzer redirects to this page. An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample typically fossil fuel flue gas for its oxygen , carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use. Construction The apparatus consists essentially of a calibrated water jacketed gas burette connected by glass capillary tubing to two or three absorption pipettes containing chemical solutions that absorb the gasses it is required to measure. For safety and portability, the apparatus is usually encased in a wooden box. The absorbents are Potassium Hydroxide Caustic Potash Alkaline pyrogallol ammoniacal Cuprous chloride The base of the gas burette is connected to a levelling bottle to enable readings to be taken at constant pressure and to transfer the gas to and from the absorption media. The burette contains slightly acidulated water with a trace of chemical indicator typically methyl orange for colouration. Method of analysis By means of a rubber tubing arrangement, the gas to be analyzed is drawn into the burette and flushed through several times. Typically, 100mls is withdrawn for ease of calculation. Using the stopcocks that isolate the absorption burettes, the level of gas in the leveling bottle and the burette is adjusted to the zero point of the burette. The gas is then passed into the caustic potash burette, left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements. The process is repeated to ensure full absorption. After leveling the liquid in the bottle and burette, the remaining volume of gas in the burette indicates the percentage of carbon dioxide absorbed. The same technique is repeated for oxygen, using the pyrogallol, and carbon monoxide using the ammoniacal cuprous chloride. References Boiler House and Power ... more details

Orphan date February 2009 Leon Warnerke W adys aw Ma achowski . Polish engineer and inventor in the field of photography, independence activist and revolutionary. Leon Warnerke have been a pseudonym . His real name is W adys aw Ma achowski. W adys aw Ma achowski was born on 26 May 1837 to an Polish Lithuanian Commonwealth Polish Lithuanian szlachta family in manor Macie, Grodno Governorate , Polish Lithuanian Commonwealth Lithuania , Russian Empire today Belarus . He graduated from the Petersburg State University of Means of Communication Corps of Railroad Engineers in 1859. In 1863 he joined the January Uprising , and then entered the National Government in Vilnius . After the uprising chased by police, fled with his wife on board the English ship to the UK. He settled in London , under the name Leon Warnerke. He died 7 October 1900 in Geneva , Switzerland . He made many inventions in the field of photography. Ma achowski, first developed in 1875 the camera system, which acted like modern cameras. His system was based on the photosensitive layer of collodion process dry collodion imposed on the paper covered with a layer of gum arabic . After exposure, the layer of collodion was through a complex process, transferred to a glass substrate. This material is also suitable for printing positive. Photosensitive material in a roll was placed in a special cartridge which allows to perform up to 100 photos. The design of this camera was based on entirely new solutions that allow for the first time to perform such a large number of images on a single cartridge is loaded. Unfortunately, high production costs have prevented the proliferation of these films and their disposal. Ma achowski in 1880 invented the first practical Sensitometry sensitometer , which allows measurement of the Film speed speed of photographic materials . He also discovered the phenomenon of tanning the exposed parts gelatin emulsion by Pyrogallol pyro developer , which later found its application in Bro ... more details
