Magnetization Control of Magnetic Liquids for Sink-Float Separations
The cut-density of sink-float separations with water-based magnetic liquids linearly depends on the magnetization of the process liquid. The control of the magnetization of the liquid, by means of measurement followed by extraction of water from the process liquid by membranes or mixing with water or concentrated magnetic liquid, is therefore a critical part of the technology. A potential probl...

15 صفحه اولA new apparatus for visual field testing with binocular fixation.
A new instrument for visual field examination with binocular fixation is described. The binocular vision was dissociated with polarizing plates. Only the point of fixation was visible to both eyes while the testing chart (Amsler chart) was visible to one eye in the use of this apparatus. The examination was done with both the patient's eyes open. With the use of this apparatus, not only was the...
متن کاملMicro Machining of AISI 440C Stainless Steel using Magnetic Field and Magnetic Abrasive Particles
Magnetic abrasive finishing (MAF) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. In this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of Al<...
متن کاملAccuracy of float testing for metered-dose inhaler canisters.
OBJECTIVE To characterize and evaluate canister floating patterns of three commercially available metered-dose inhalers (MDIs) with varying amounts of medication remaining. DESIGN Four canisters each of three asthma medications were studied. MDIs were actuated every 30 seconds to 60 seconds, and canisters were weighed and floated at 100%, 75%, 66%, 50%, 33%, 25%, 10%, and 0% of remaining labe...
