ASR Technology. 1  ControlMaster Elite VFD + A-motor = ASR. 2  Intelligent speed control - the right speed at the right time! 3  Extended speed range at light loads (<40 4 %) Adjustable speed range at heavier loads (> 40 %) Rated speed at full load is half the rated speed of equivalent 2-speed hoist.
The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal. Pyrite is the most common of the sulfide minerals. The name pyrite is derived from the Greek ÏÏÏÎ¯ÏÎ·Ï (pyritÄs), of fire or in fire, in turn from ÏÏÏ (pyr), fire.
Specific Gravity (1.002 â 1.035). 1  Specific gravity of urine is a measure of the amount of solutes dissolved in urine as compared to water (1.000). 2  Specific Gravity measures the ability of the kidney to concentrate or dilute the urine and is directly proportional to urine osmolality (solute concentration). Specific Gravity measures the ability of the kidney to concentrate or dilute the urine and is directly proportional to urine osmolality (solute concentration). 2  Specific gravity between 1.002 and 1.035 on a random sample is normal IF kidney function is normal.
