Abstract: A brushless direct current motor is energized by a power stage. Switches of the power stage are selectively switched by an electronic control device. In order to determine the correct commutation pattern, without using rotor position indicators such as Hall effect devices, the control device is arranged to sample the power fed to the motor. The samples, each responsive to a test signal or normal energization pulses received by the motor, in a ordered sequence define an analogue function whose parameters can be determined by mathematical analysis. The analysis applied to the samples derives the necessary commutation information and the energization signals in a rapid manner by employing a vector or complex number addition based on functions dependent on variable inductance in the operation of the motor.

Abstract: What is disclosed is a method of encapsulating hydrocarbon systems with the combination of an emulsifier solution and a reactive silicate solution. The method comprises the addition of an emulsifier solution to a hydrocarbon, for example, crude oil, then adding the reactive silicate solution to the emulsifier solution and hydrocarbon mix. Upon adding the reactive silicate solution the mix changes to a thick gel consisting of agglomerates of microspheres having typical diameters of 2 to 4 micrometres and less. The agglomerates are only loosely bound and the microspheres are easily dispersable into individual entities. Upon drying the wet gel yields a free-flowing powder. The encapsulation does not chemically alter or degrade the oil in any way.
