experimental approach to polarimetric density measurement on ft machine

an experimental study of plasma bi-refringence (cotton-mouton effect) in the ft plasma carried out by using an hcn laser (337 $mu$ m) is reported. the experiment is intended to test the feasibility of polarimetric plasma density measurements in high-toroidal-field tokamaks. the results show that for a plasma density of n//e $equals$ 10**1..

what to expect when logging the cotton valley trend

exploration within the low-porosity, low-permeability sections of the cotton valley sands and limestones of east texas, louisiana and arkansas has proven economic only within the last five to eight years due to improved gas prices and advanced reservoir analyzation and stimulation techniques. this report details those logging suites neces..

cotton dust particle size distribution in oil mills

analytical procedures have been developed for characterizing the size and shape of cotton dust particulates collected by the vertical elutriator (ve) sampler. data are reported for dust distributions on ve filters collected from different processing areas (cleaning, delintering, hulling, and baling) in cotton seed oil mills. results of pa..

status of efforts by oil mill machinery manufacturers to control fugitive dust emissions

this paper shows how delintering equipment has been successfully equipped with canvas drapes connecting the feeder to the top of the roll box front as well as hinged doors that connect the black seed chutes to the bottom of the roll box. dust and noise levels have been reduced, but not eliminated. rock and shale traps between the white se..

economics of occupational cotton dust control in cottonseed oil mills

in the reported study, an economic analysis of the total cost for various dust control systems for a 500 ton/day model cottonseed oil mill has been performed. all cost data have been adjusted to reflect may 1981 prices. cost data are presented for the dust collection system, cyclone(s), baghouse(s) and prime air mover(s) for each major pr..

evaluation of occupational dust control technology in cottonseed oil mills

occupational cotton dust control technology was evaluated in 10 oil mills throughout the cotton belt of the u. s. this evaluation was restricted to mechanical portions of each mill: seed cleaning, delintering, hulling and separating, and linter baling. based on the process machinery observed in these mills, a 500 ton/day model cottonseed ..

symposium on cottonseed oil mill dust, presented at the annual meeting of the american oil chemists' society, 72nd, 1981

in this magazine there are proceedings of 7 papers delivered at the meeting. the topics covered are related to dust control in cottonseed oil mills. the following subjects are discussed - osha standards as requirements for health protection of mill personnel; equipment used for dust separation (air fibers, baghouses, cyclones, etc); dust ..

qualitaetskontrolle von leiterplatten mit widerstandsmessungen $left bracket$ quality control of printed circuit boards by measurement of resistances $right bracket$

guidelines are offered for the measurement of essential parameters of p/c boards. these include: surface and volume resistance of the basic material, the isolation resistance between printed lines, and the volume resistance of printed conductors, particularly through connections. both dc and ac measurements are discussed. in german

optical properties of zinc sulphide thin films prepared by sublimation in ultrahigh vacuum and by r. f. sputtering in argon

thin films of zinc sulfide, in single-crystal and in polycrystalline form, were grown by vacuum deposition methods onto silicon and gallium arsenide substrates. the thin film optical constants are determined from a computer solution of the optical waveguide dispersion relationship for measured effective indices and loss of guided modes ex..

cotton: from seed to mill

this is a review paper which reports on recent r&&d in the field of cotton growth and coffee industry in pakistan. the discussion is presented in 6 parts - cotton growth $left double quote$ from field to factory $right double quote$ ; cotton research; education and training; carpet manufacture; achievement of nishat mills in production, s..
