Download or read book Influence of Quality of Gas and Other Factors Upon the Efficiency of Gas Mantle Lamps Classic Reprint written by R. S. Mcbride and published by Forgotten Books. This book was released on 2017-10-27 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Influence of Quality of Gas and Other Factors Upon the Efficiency of Gas-Mantle Lamps Btu, and of coal gas of 56 5 Btu, these were selected as the typical gases to be studied. For the sake of comparison and further study of certain variables, some specially enriched gases of higher heating value were also used in a few cases. Since typical commercial gases vary from time to time within certain limits, both as to com position and heating value, it was not considered necessary to maintain exactly the same quality of gases throughout the various series of tests; nor was it practicable to do so. An effort was made, however, to prevent as far as possible variations between sets of observations which were intended to be comparable.

Download or read book Photometry of the Gas Filled Lamp Classic Reprint written by G. W. Middlekauff and published by Forgotten Books. This book was released on 2018-02-11 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Photometry of the Gas-Filled Lamp As the filament has a positive temperature-resistance coefficient, the resistance decreases and consequently the current increases at constant voltage. At high values of voltage the mean temperature of the gas is higher than at low voltage, consequently the tempera ture of the filament is reduced in a lesser degree by rotation and the change in current, though positive, is less at high than at low voltage. On the other hand, when the lamp is rotated at high speeds the cooler gas at the bottom of the bulb is thrown out by centrifugal force, which varies as the square of the speed, and the hot gas tends to remain near the center, thus considerably retarding the convection currents which cool the filament. The result is an increase in the resistance of the filament as a whole and a decrease in the value of the current. At high voltages the mean tempera ture of the gas is higher than at low voltage and the retarding efiect due to centrifugal force is decreased; hence the change in current due to rotation is less than at low voltages. At low speeds, as seen above, the temperature of the filament is lowered and consequently the candlepower is decreased. At high speeds the temperature of the filament is raised, and hence there is an increase in the candlepower.

Download or read book The Pentane Lamp as a Working Standard Classic Reprint written by E. C. Crittenden and published by Forgotten Books. This book was released on 2018-02-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Pentane Lamp as a Working Standard Since all flames depend upon combustion it is to be expected that their intensity will vary with the proportion of oxygen and Of other constituents in the air supplied to the gaseous fuel of the flame. T O maintain a flame in a constant condition requires, therefore, not only uniform fuel, but also a uniform proportion Of oxygen in the air supplied to the flame. Good ventilation is con sequently desirable for all work with flames, and is indispensable where lamps Of other kinds are to be compared with a flame standard. The quantity Of air which must be supplied depends largely on the size and number Of flames in the room and also on the method of ventilating. The flames themselves set up currents of air, and if possible these currents should be utilized to remove immediately from the room all the vitiated air coming from the lamps. A hood placed above the photometer with a rising pipe to lead the warm air out of the room is most effective. If the gases from the flames are allowed to diffuse into the room and are simply diluted by the air entering, a much larger amount Of fresh air will be needed. In such a case it has been estimated 5 that to keep the carbon dioxide content of the air down to 6 parts in 10 000, 3000 cubic feet of fresh air per hour must be supplied for each person in a room. A committee Of the American Gas Institute 6 has on this basis estimated that 36 900 cubic feet Of air per hour should be supplied for a photometer room where two persons work with a pentane lamp and a 5-foot gas flame, since in the production Of carbon dioxide the gas flame is approximately equivalent to six persons and the pentane lamp to four. In a room where air enters at the bottom and escapes at or near the top the quantity estimated as above (about I 2 000 cubic feet per hour for a pentane lamp) is probably ample for any purpose, and if care is taken to allow direct escape Of the flame gases a much smaller amount is sufficient.

This book was released on 2012-12-15 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twelve chapters of this volume aim to provide a complete manual for using noble gases in terrestrial geochemistry, covering applications which range from high temperature processes deep in the Earth’s interior to tracing climatic variations using noble gases trapped in ice cores, groundwaters and modern sediments. Other chapters cover noble gases in crustal (aqueous, CO2 and hydrocarbon) fluids and laboratory techniques for determining noble gas solubilities and diffusivities under geologically relevant conditions. Each chapter deals with the fundamentals of the analysis and interpretation of the data, detailing sampling and sampling strategies, techniques for analysis, sources of error and their estimation, including data treatment and data interpretation using recent case studies.
Download or read book Advanced Strategies in Thin Film Engineering by Magnetron Sputtering written by Alberto Palmero and published by MDPI. This book was released on 2020-12-10 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed the flourishing of numerous novel strategies based on the magnetron sputtering technique aimed at the advanced engineering of thin films, such as HiPIMS, combined vacuum processes, the implementation of complex precursor gases or the inclusion of particle guns in the reactor, among others. At the forefront of these approaches, investigations focused on nanostructured coatings appear today as one of the priorities in many scientific and technological communities: The science behind them appears in most of the cases as a "terra incognita", fascinating both the fundamentalist, who imagines new concepts, and the experimenter, who is able to create and study new films with as of yet unprecedented performances. These scientific and technological challenges, along with the existence of numerous scientific issues that have yet to be clarified in classical magnetron sputtering depositions (e.g., process control and stability, nanostructuration mechanisms, connection between film morphology and properties or upscaling procedures from the laboratory to industrial scales) have motivated us to edit a specialized volume containing the state-of-the art that put together these innovative fundamental and applied research topics. These include, but are not limited to: • Nanostructure-related properties; • Atomistic processes during film growth; • Process control, process stability, and in situ diagnostics; • Fundamentals and applications of HiPIMS; • Thin film nanostructuration phenomena; • Tribological, anticorrosion, and mechanical properties; • Combined procedures based on the magnetron sputtering technique; • Industrial applications; • Devices.
