When measuring GRG recovery, separate GRG from non-GRG to measure both total gold and GRG recovery. • For low unit recoveries or when size-by-size performance is sought, sample concentrate and tailing streams as well as measure yield. • For optimizing continuous units, a measure of recov...

Rotary compensating rotation-frequency converter The rotary compensating converter (RCC) developed by us [I] can be used as a universal converter for measuring and adjusting rotation frequencies of various objects in the range of 10-a-105 rpm. The RCC differs from existing converters b... VA Zi...
We measure an earthquake’s strength on the Richter Scale. The Richter Scale was introduced in 1935 in Southern California in the USA. It measures earthquakes on a scale of one to ten. Any earthquake measuring five or more is usually serious. ...

The coupled thickness-twist and face-shear vibrations of the lateral-field-excitation (LFE) two-unit resonator array are analyzed, and the frequency interference and shift of LFE resonator arrays are both studied. Different from most of the quartz resonator arrays based on thickness-field-excitation...
